Gas extraction hood modeling in a steel converter for energy recovery using phase change materials

The steel industry is characterized by its energy-intensive processes. The steel forming process stands out, where the oxidation of carbon, when reacting, generates incomplete combustion gases at high temperature through the process basic oxygen injection in the furnace (BOF). A model of intermittent process and high temperature gas collection system is proposed and validated through experimental measurements. Through it, energy improvement opportunities are analyzed, highlighting energy recovery from high temperature flue gases by incorporating a phase change material (PCM) method for temporary energy storage. It was estimated that the fumes inside the hood could provide 77 GJ of available energy during the 15 min of oxygen injection (blowdown). With the use of a PCM device, between 13% and 32% residual energy recovery is obtained, equivalent to 10–25 GJ. In this way, a continuous heat flow could be generated during the whole process for steam generation through a cooling system in the gas collection system, with an electricity generation potential with a Rankine cycle of 14.5 MW.

Assessing logging residues availability for energy production by using forest management plans data and geographic information system (GIS)

The aim of the work was to quantify the mass of logging residues (branches and tops; t yr−1 dry matter, DM) for energy generation starting from Forest Management Plans (FMP) data. The methodology was applied to public stands of an Italian district (area: 3.60 × 104 ha; period: 2009–2018). Compared to the previous preliminary analysis, the potentially available residues were computed considering forest accessibility and road traversability, by combining FMPs data with a geographic information system (GIS). New issues that were assessed here were: (i) representation of stands consisting of multiple disconnected parts; (ii) calculation of producible residues by using different values of biomass expansion factors (Scenario 1, S1; Scenario 2, S2). The potentially available residues computed for the analyzed period were used to quantify the current sustainable supply. Then, the potentially generated heat (thermal energy, TE; GJ yr−1) and electricity (EE; GJ yr−1), and the potentially avoided CO2 emissions into the atmosphere (EM; t yr−1 CO2) related to the final combustion process were computed by assuming that the current supply of residues was used as woodchips in a local centralized heating plant currently operating. For both S1 and S2, the large difference between the potentially producible and the potentially available residues demonstrated that geodata are essential for reliable estimations. Moreover, as the required information for the GIS analysis can be easily found in databases made available by forestry authorities, the proposed approach can be applied also to other areas; this could be helpful to support local decision-makers in defining sustainable practices for residues recovery.

New sustainable and robust catalytic supports for palladium nanoparticles generated from chitosan/cellulose film and corn stem biochar.

The production of sustainable catalytic supports for palladium nanoparticles is always desired, even more so through the recovery of biomass residues. In this sense, two different solids were investigated — chitosan/cellulose film and corn stem biochar — as catalytic supports of palladium nanoparticles. The solids were carefully characterized and tested in the Suzuki-Miyaura reaction, a typical cross-coupling reaction. The developed catalytic systems proved to be efficient and sustainable, promoted the formation of target products very well, and demanded green reactants under environmentally appropriate conditions. With the results shown in the manuscript, it is expected to contribute to the valorization of biomass and agro-industrial residues in the development of new catalysts for the chemical industry.Graphical abstract Supplementary InformationThe online version contains supplementary material available at 10.1007/s11356-022-22616-6.

Research progress on the influence of geopolymer grouting material properties

Grouting technology is to inject slurry with cementing ability into the cracks and voids of the formation to achieve the purpose of reinforcement and filling. At present, cement-based materials are mainly used for grouting, which has the advantages of mature technology, cheap price, high stone strength and wide application, but there are also defects such as high-water separation rate, poor stability and long setting time. Most importantly, the production of cement materials consumes a lot of energy and emits a lot of CO2, which aggravates the global greenhouse effect and is not in line with the concept of sustainable development. In recent years, geopolymer materials based on volcanic ash and industrial waste residue have attracted extensive attention of scholars because of their green and environmental characteristics, and have been gradually applied in the field of grouting. Geopolymer is a new inorganic cementitious material formed by leaching the active components (Si, Al, and other elements) from industrial wastes such as fly ash, slag, and steel slag using chemical alkali activation technology (AAT) and further recombination. Using geopolymer as grouting material has two advantages :(1) geopolymer has a wide source of raw materials and low cost, which can effectively reduce the cost of grouting engineering; (2) Compared with cement materials, geopolymer materials have the advantages of low energy consumption, green environmental protection and other advantages, which can realize the effective recovery and reuse of industrial waste residue, reduce a large amount of CO2 emissions, and have far-reaching environmental and social benefits. Among them, temperature is an important factor affecting the properties of geopolymer grouting cementitious materials. In this paper, the effects of the selection of aluminosilicate raw materials, the fineness of raw materials, the ratio of liquid to solid, the type and modulus of alkali activator, and the temperature conditions on the properties of geopolymer grouting cementitious materials are comprehensively combed.

Plastic-film-side seeding, as an alternative to traditional film mulching, improves yield stability and income in maize production in semi-arid regions

Planting under plastic-film mulches is widely used in spring maize production in arid-cold regions for water conservation and warming the soil. To ameliorate the associated issues such as plastic-film residues and additional labor during the “seedling release” in spring maize production, we have developed a plastic-film-side seeding (PSS) technology with the supporting machinery. In the semi-arid regions of Northwest China, a 7-year trial demonstrated that PSS increased plant number per hectare by 6 547 and maize yield by 1 686 kg ha–1 compared with the traditional method of seeding under plastic-film mulch (PM). Two-year experiments were conducted in two semi-arid regions to further understand the effects of PSS on three important aspects of production: (i) the moisture and temperature of soil, (ii) maize development, yield output, and water use efficiency (WUE), and (iii) the revenue and plastic-film residuals in comparison with that of flat planting (CK) and PM. Continuous monitoring of the soil status demonstrated that, compared with CK, the PSS treatment significantly increased the temperature and moisture of the 0–20 cm soil in the seeding row at the early stage of maize development, and it also promoted grain yield (at 884–1 089 kg ha–1) and WUE, achieving a similar effect as the PM treatment. Economically, the labor inputs of PSS were equal to CK, whereas the PM cost an additional 960 CNY ha–1 in labor for releasing the seedlings from below the film. Overall, the PSS system increased profits by 5.83% (547 CNY ha–1 yr–1) and 8.16% (748 CNY ha–1 yr–1) compared with CK and PM, respectively. Environmentally, PSS achieved a residual film recovery rate of nearly 100% and eliminated 96 to 130 kg ha–1 of residual plastic-film in PM in 3–5 years of maize production. Collectively, these results show that PSS is an eco-friendly technique for improving yield stability and incomes for the sustainable production of maize in semi-arid regions.

Organic waste recycling for carbon smart circular bioeconomy and sustainable development: A review

The development of sustainable and low carbon impact processes for a suitable management of waste and by-products coming from different factors of the industrial value chain like agricultural, forestry and food processing industries. Implementing this will helps to avoid the negative environmental impact and global warming. The application of the circular bioeconomy (CB) and the circular economic models have been shown to be a great opportunity for facing the waste and by-products issues by bringing sustainable processing systems which allow to the value chains be more responsible and resilient. In addition, biorefinery approach coupled to CB context could offer different solution and insights to conquer the current challenges related to decrease the fossil fuel dependency as well as increase efficiency of resource recovery and processing cost of the industrial residues. It is worth to remark the important role that the biotechnological processes such as fermentative, digestive and enzymatic conversions play for an effective waste management and carbon neutrality.

Evaluation of load-independent microhardness values in Plateau regions of Vanadium substituted Bi-2212 ceramics

This study reveals extensively effect of homovalent V/Bi partial replacement in Bi2.0−xVxSr2.0Ca1.1Cu2.0Oy ceramic matrix (0.00 ≤ x ≤ 0.30) on the key mechanical design performance parameters and load-independent Vickers microhardness parameters in plateau limit region by means of experimental microhardness tests and semi-empiric approaching models. It is found that the vanadium substitution level of x = 0.01 is observed to be optimum amount in the Bi-2212 crystal lattice for refinement of fundamental mechanical properties due to the enhancement in stabilization of durable tetragonal phase, surface residual compressive stress and elastic recovery mechanism. Conversely, from the replacement level of x = 0.01 onwards, the lattice strain field and stress concentration sites enhance significantly depending on the increase of microscopic structural problems, interaction problems between adjacent layers and crack-initiating flaws in Bi-2212 ceramic system. Correspondingly, stress-induced phase transformation begins to play predominant role, and excess vanadium substituted ceramic materials are easily broken at relatively smaller test load. Moreover, the models indicate that every ceramic compound shows standard indentation size effect (ISE) feature due to predominant behavior of elastic recovery in crystal structure. Hence, presence of optimum vanadium ions strengthens typical ISE characteristic behavior. Furthermore, among semi-empirical models the indentation-induced cracking (IIC) model exhibits the highest performance to inspect real microhardness values of Bi2.0−xVxSr2.0Ca1.1Cu2.0Oy ceramic compounds in the plateau limit region.

Effective and simultaneous removal of heavy metals and neutralization of acid mine drainage using an attapulgite-soda residue based adsorbent

Implementing an economical and effective measure for treating acid mine drainage (AMD) from abandoned mines using low-cost restoration reagents present a significant challenge. In this study, natural attapulgite (AT) and soda residue (SR) composite particles (AT-SR) were firstly prepared and utilized in AMD treatment. The efficiencies and mechanisms of AT-SR composites for regulating acidity and removing metals in AMD, the critical factors influencing the treatment efficiencies, and the regeneration performance and environmental risk were investigated. It is illustrated that AT and SR quality ratio of 5:5, dosage of 0.5 g L−1, particle size < 1.5 mm, concentrations of 150 mg L−1 for Fe, 75 mg L−1 for Mn and 100 mg L−1 for Cu, Zn, Cd and Pb, and adsorption time of 120 min were the optimized conditions. The maximum adsorption capacities of Fe, Mn, Cu, Zn, Cd and Pb under single metal scenarios were 51.61, 22.30, 37.05, 40.21, 37.39 and 49.53 mg g−1, respectively. Under the mixed metal scenarios, competitive adsorption was predominated with the rate constants in the reducing order of 3.169 for Fe > 0.841 for Cu > 0.657 for Pb > 0.083 for Zn > 0.024 for Cd > 0.006 for Mn. The experimental data was fitted well with the pseudo-second-order and the Freundlich isotherm models. AT-SR is an outstanding neutralizer for AMD due to its richness in calcium and magnesium oxides and the spent AT-SR composites could be easily regenerated while maintaining high metal removal efficiencies under the subsequent usages. It is determined under the aqua regia digestion and Toxicity Characteristic Leaching Procedure (TCLP) tests that AT-SR can be used safely without posing environmental risks, thus promoting the resource recovery and utilization of soda residue and providing a green and effective method for treating AMD.

Airside thermal-hydraulic and fouling performances of economizers with integrally-molded spiral finned tubes for residual heat recovery

Without defects inherent in conventional welded finned tubes, nonwelded integrally-molded spiral finned (IMSF) tubes proposed here have “zero” contact thermal resistance and high joint strength out of trapezoidal cross-section of the fin, and thus greatly improve thermal performances and service life of economizers for residual heat recovery. To guide the applications of this new economizer, a three-dimensional physical-numerical model is established to study airside thermal-hydraulic and fouling performances of the economizer with IMSF-tubes. We investigate the effects of longitudinal and transverse pitches of finned tube bundles on the airside thermal-hydraulic and fouling performances of IMSF-tubes at various Reynolds numbers. The results show that a longitudinal pitch more than 80 mm is suggested for economizer design to avoid working instability of boiler systems due to high pressure drop at small longitudinal pitch, and as compromised, a transverse pitch of an economizer may be more than 100 mm since a small transverse pitch improves thermal-hydraulic performance, but worsens fouling and raises pressure drop. We also put forward new correlations of the Colburn and Fanning friction factors for the IMSF-tube economizer. Compared with other finned tubes, IMSF-tubes improve not only mechanics but also thermal-hydraulic performances of heat exchangers. Our research work may contribute to applications of IMSF-tube economizers for residual heat recovery.

Experimental Study of Inductive Pulsed Power Supply Circuit With Residual Energy Recovery Branch

Inverse current commutation with semiconductor devices (ICCOS) has been proved to be able to shut off the high current of inductors. Inductive pulsed power supply (IPPS) is considered to have great potential in the field of Electromagnetic Launch (EML) due to its high energy density and fast discharge speed. A repetitive IPPS circuit with ICCOS technique has been proposed based on a high-temperature superconducting pulsed power transformer (HTSPPT) in our previous studies. This circuit can recover the remaining energy and generate continuous current pulses. However, due to the low voltage of the primary power supply, the circuit uses the primary power supply to recover the remaining energy, resulting in a slower process of recovering the remaining energy. For this issue, this article proposes a method to improve the original circuit by adding a residual energy recovery branch on the secondary side. The new circuit can recover most of the remaining energy on the secondary side through a designated capacitor. The working process of this circuit is illustrated detailed in this article, and the preliminary simulation verification is carried out. To further study the feasibility of this circuit, an experimental platform was built with a small HTSPPT. Experimental results and comparative analysis show that the new circuit has better characteristics in terms of remaining energy recovery and increasing pulse amplitude.

Effect of blade width on ultra-low specific speed axial turbines

ABSTRACT Ultra-low specific speed axial turbines for cooling tower have some issues, such as low head, low efficiency, and turbulent internal flow. According to the orthogonal experiment and CFD analysis, it was found that the blade width was the main factor affecting the head, while the numbers of stay vanes and blades were the main factors affecting the efficiency. To further optimize the hydraulic performance of ultra-low specific speed axial turbines, six models of ultra-low specific speed axial turbines with different blade widths were designed. CFD numerical simulations showed that at different flow rates, with increasing blade width, the head gradually decreases and the efficiency shows a trend of first increasing and then decreasing. For the ultra-low specific speed axial turbine designed in this paper, when the blade width is 35 mm, the water head is 6.75 m, which meets the requirements of cooling tower turbines on head. At this blade width, the turbine achieves the highest efficiency of 81.15%, its flows are uniform, performance is stable. The internal flow field and pressure distribution of the runner are in better agreement with the design indexes of an ultra-low specific speed axial turbine. Thus, a high-efficiency ultra-low specific speed axial turbine suitable for cooling tower residual energy recovery is preferably selected.

Investigation of biogas for enhancing oil recovery with indigenous microorganism in high salinity oil field

The feasibility of microbial enhancing oil recovery (MEOR) by biogas in Qinghai oil field with hypersalinity was studied. Different nutrient packages (molasses, coin milk, and starch) for biogas production were evaluated, respectively. The indigenous microorganisms preferentially use carbon source (molasses) to produce gas, and 0.9% molasses promoted the gas production effectively, the gas/liquid ratio came up to 0.775, the biogases was composed of CO2 (54.37%), N2 (45.03%), and H2 (0.60%), and pressure reached to 0.64 MPa. The effect of nitrate addition on microbial H2S production was also investigated. Addition of 0.2% nitrate led to complete elimination of sulfate-reducing bacteria. Because the microbial community significantly influences the results of the application of MEOR, so the microbial community structure dynamics was also analyzed by denaturing gradient gel electrophoresis (DGGE). Species were confirmed mainly to Halomonas sp. and some uncultured bacteria. In sand pack experiment, the acetate concentration in the experimental group achieved to 15.8 mM, and the residual oil recovery was 7.27% which exhibited a great potential to enhance oil recovery.

Experiment and Analysis of Film-Soil Separation Motion Characteristics of a Chain Drive Residual Film Recovery Mechanism for the Tillage Layer

The working principle and key components of a chain drive residual film recovery machine were studied. A kinematic analysis of the chain drive soil separation mechanism was completed by applying ADAMS software to obtain the trajectory, displacement, velocity and acceleration of the center of mass of the chain plate link_1 in the x- and y-directions within the effective shaking displacement. A field test of the chain drive separation mechanism was carried out. When the shaking roller was in contact with the chain, the change in speed of the chain in the x- and y-directions was not significant, but the force in the y-direction was conducive to breaking the soil pieces and improving the rate of collecting the residual film. The change in the speed of link_1 in the y-direction speed with x-direction speed explained the action of the separation mechanism on conveying and throwing of the film-soil mixture in the horizontal and vertical directions, which revealed the mechanism of the chain drive film-soil separation equipment. The field test showed that the film collection rate of the chain drive separation mechanism was 68%, and the surface residue was 6%. The test results meet the relevant national and industry standards and design requirements. The results of this study provide guidance for the design and optimization of chain drive film-soil separation equipment.

Enhancing N[formula omitted] and CO[formula omitted] foam stability by surfactants and nanoparticles at high temperature and various salinities

To keep up with the ever-growing global energy demand, the petroleum industry has shifted its attention to enhanced oil recovery (EOR) methods, which ensure 30%–60% of residual oil recovery following primary and secondary recovery processes. Foam injection is one of these methods. Due to their low sensitivity to gravity and permeability heterogeneities which improve sweep efficiency, foams are preferable injection fluids than water or gas. However, this recovery technique is not widely used due to the thermodynamic instability of foams. This work aims to take advantage of recent breakthroughs in nanoparticles engineering to build long-lasting nanoparticle-stabilized foams, as nanoparticles can withstand high temperatures and reservoir conditions for a prolonged time. Therefore, to achieve this goal, a comprehensive set of screening experiments was conducted, which included an investigation of the influence of ionic surfactants on foam stability with and without silica nanoparticles at room and elevated temperatures, as well as bulk foam tests with air, nitrogen, and CO2, characterization of foaming suspensions, and analysis of foam texture and morphology. The half-life duration, foam quality, and foam composite index were used to determine the stability of the generated foams. The findings demonstrated that the addition of 0.05% silica nanoparticles could improve the half-life of nitrogen and CO2 foam up to 13% and 40%, respectively. However, the extent of this depends on temperature, salinity and optimal concentration of nanoparticles. Furthermore, the results showed that optimal concentrations of nanoparticles and surfactants should be carefully determined in order to achieve a positive synergistic effect. Results illustrated that selected nanoparticles–surfactant formulations appear very promising for EOR as they show high stability at elevated temperatures and tolerance to different mineralization.

Enhanced Oil Recovery using a Combination of Biosurfactants.

Biosurfactants are surface-active compounds capable of reducing the surface tension between two phases of different polarities. Biosurfactants have been emerging as promising alternatives to chemical surfactants due to less toxicity, high biodegradability, environmental compatibility and tolerance to extreme environmental conditions. Here, we illustrate the methods used for screening of microbes capable of producing biosurfactants. The biosurfactant producing microbes were identified using drop collapse, oil spreading, and emulsion index assays. Biosurfactant production was validated by determining the reduction in surface tension of the media due to growth of the microbial members. We also describe the methods involved in characterization and identification of biosurfactants. Thin layer chromatography of the extracted biosurfactant followed by differential staining of the plates was performed to determine the nature of the biosurfactant. LCMS, 1H NMR, and FT-IR were used to chemically identify the biosurfactant. We further illustrate the methods to evaluate the application of the combination of produced biosurfactants for enhancing residual oil recovery in a simulated sand pack column.

Research and Experiment on the Removal Mechanism of Light Impurities of the Residual Mulch Film Recovery Machine

Aiming at the problem of high impurity rate in the recycled residual film, combined with the existing installation (4JMLE-210 agricultural residual film recycling machine), the removal mechanism of light impurities on the film surface was analyzed. The statics and kinematics analysis of light impurity particles in different spatial positions were carried out to determine the conditions for the movement of impurity particles. By analyzing critical conditions, such as ideal collision and throwing capacity, the structural dimensions of the straight pipe section and its outlet section were determined. Using Origin 2018 software, the movement track of the impurity particles left from the upper and lower limit positions and the ideal curve of the throwing arc were plotted, and the trapezoidal section was determined at the outlet of the throwing arc section. Finally, trial-produce prototype, and a field test was carried out on the performance of the machine by selecting the impurity rate in the recovered residual film as the test index. The results showed that when the forward speed of the machine and the rotating speed of the cutter roll were in the range of 5.4–5.8 km/h and 1440–1460 r·min−1, the light impurity rate and working efficiency could keep a good balance. The light impurity rate in the recovered residual film was between 10.9% and 31.4%, and the average light impurity rate was around 18.7%, which met the design and application requirements.

An ultra-thin silicon nitride membrane for label-free CTCs isolation from whole blood with low WBC residue

Microfiltration is the most straightforward and effective method to enrich circulating tumor cells (CTCs) from large numbers of background blood cells in the peripheral blood. It is still very challenging to achieve both high recovery of CTCs and low residue of white blood cells (WBCs) through one-time whole blood filtration. In this study, through a simulation, we revealed that reducing the thickness of the filter significantly reduces the WBC residue. A filter device was created using a 400-nm-thick Si3N4 membrane. The recovery rates of A549 and MCF-7 tumor cell lines were 82.04 ± 1.19% and 86.53 ± 3.27%, respectively, while the residual number of WBCs was largely reduced from 6.84 × 106 cells/mL cells to 604 ± 33.74 cells/mL. In addition, the assembled device could process whole blood without pretreatment at a high throughput of 1 mL/min. Utilizing as small volume of peripheral blood as 1 mL, CTCs were enriched by our device in four of six lung cancer patients and four of five breast cancer patients. The lower WBC residue is advantageous in CTC enumeration and subsequent proteomic or genomic characterization. Therefore, this technology enables label-free CTC isolation with a low WBC residue from whole blood, paving the way for a CTC analysis in clinical applications.

Residual image recovery method based on the dual-camera design of a compressive hyperspectral imaging system.

Compressive hyperspectral imaging technology can quickly detect the encoded two-dimensional measurements and reconstruct the three-dimensional hyperspectral images offline, which is of great significance for object detection and analysis. To provide more information for reconstruction and improve the reconstruction quality, some of the latest compressive hyperspectral imaging systems adopt a dual-camera design. To utilize the information from additional camera more efficiently, this paper proposes a residual image recovery method. The proposed method takes advantage of the structural similarity between the image captured by the additional camera and the hyperspectral image, combining the measurements from the additional camera and coded aperture snapshot spectral imaging (CASSI) sensor to construct an estimated hyperspectral image. Then, the component of the estimated hyperspectral image is subtracted from the measurement of the CASSI sensor to obtain the residual data. The residual data is used to reconstruct the residual hyperspectral image. Finally, the reconstructed hyperspectral image is the sum of the estimated and residual image. Compared with some state-of-the-art algorithms based on such systems, the proposed method can significantly improve the reconstruction quality of hyperspectral image.

Regulation of Paraquat for wheat crop contamination.

Paraquat is a highly toxic and persistent pesticide in soil but is still used for wheat crops in many countries. Paraquat can pose potential health hazards if it is translocated from soil into wheat grains, but no study is available for its possible translocation causing wheat grain contamination. The present study aimed at finding out Paraquat residue in wheat grains under field conditions for two crop seasons to explore the sustainability of this pesticide. The experiments were conducted scientifically under field conditions at agricultural fields Pusa, Delhi, India. The soil texture was classified as sandy loam. Paraquat dichloride 24% SL (herbicide) was applied on five fields except for control field. Paraquat in wheat grains was analyzed using HPLC equipped with a photodiode array (PDA) detector. The method of analysis was validated for the pesticide residue recovery. The results showed that there was an alarming concentration of Paraquat in wheat grains ranging between 21.6 and 49.02mgkg-1 against maximum residue level of 0.1mgkg-1. Paraquat was also found in control crop (3.1mgkg-1) due to background residue in soil even when no Paraquat was applied. Furthermore, wheat flour samples from market also gave alarming Paraquat residue (20.39, 25.88, and 27.68mgkg-1). Paraquat residue was primarily dependent on % clay in field soils. More the % clay lesser was Paraquat residue in wheat grain. Thus, Paraquat was translocated from soil into wheat grains and resulted in worrying concentration of Paraquat residue in wheat grains. Consequently, use of Paraquat for wheat crops needs to be regulated as it contaminated the soil and resulted in the wheat grain contamination posing severe health hazards for humans.

Parameters Optimization and Test of an Arc-Shaped Nail-Tooth Roller-Type Recovery Machine for Sowing Layer Residual Film

The aim of this paper is to optimize the working parameters of the arc-shaped nail-tooth roller-type recovery machine for sowing layer residual film. Firstly, the tooth roller device of the residual film recovery machine is designed, and the main working parameters affecting the operation of the machine and the value range of each parameter are determined through the analysis of the operation process. Secondly, virtual simulation technology is used to establish a virtual simulation model of the interaction process between the tooth roller device and soil. At the same time, taking the soil-hilling quantity as the index, we build a quadratic regression mathematical model with three factors—the forward speed, rotation speed, and working depth—using the Box–Behnken method. Consequently, the analysis of the simulation results show that the order of the most significant factors is working depth, rotation speed, and forward speed. The optimal combination of working parameters are as follows: a forward speed of 4.5 km/h, a rotation speed of 43.2 r/min, and a working depth of 100.0 mm. Meanwhile, the predicted value of the soil-hilling quantity is 23.1 kg. Finally, we carried out field tests using the optimal combination parameters; the results show that the normal residual film collection rate is 66.8%, the soil-hilling quantity is 24.2 kg, and the relative error between the test value and the predicted value is 4.8%. This indicates that the devised DEM simulation model can be used to predict the operational performance of the tooth roller device in the working process. This study provides a reference that can be used in the planning and boundary enhancement of agricultural machinery and equipment.
