Abstract
For the past decades, the flue gas emitted from municipal solid waste incinerator, power plant, and various industries is a permanent problem for the environment and has been affecting human life. Many flue gas filtration devices have been emerging out over the years. Although the electrostatic precipitator was an appropriate device due to high filtration efficiency and little pressure drop and energy efficiency, the cost and design of the electrostatic precipitator is a major restriction for manufacturers and end-users. With recent advances in technology, designing a cost-effective and less complex electrostatic precipitator has become mandatory. This article aims to design and develop a solar-powered cost-effective needle-plate type electrostatic precipitator which includes a static power converters and high-voltage transformer-rectifier (T-R) set with an input voltage as 230V AC, output voltage as 80-kV direct current (DC), and output current of 40mA for mitigation of flue gas emissions exhaust from municipal solid waste incinerator. The analysis of flue gas at ESP inlet and outlet has been performed using Ecotech stack sampler and flue gas analyzer. The obtained experimental results are validated with emission standards provided in the Solid Waste Management rules book, India, 2016.
Highlights
Municipal Solid Waste (MSW) Management, a decisive factor in the direction of sustainable urban growth, includes characterization, storage, treatment, segregation, collection, and disposal of solid waste to reduce its harmful impact on the atmosphere (Kumar et al, 2009)
MSW is treated in three ways, such as incineration, landfilling, and recycling (USEPA, 2012).The incinerationmethod of treatment is cost-effective and ash produced from this treatment method canproduce expensive materials (Huang et al, 2006).The Primary advantage of incineration is the reduction of waste quantity,thereby space required for landfills is decreasedandprovides additional energy sources from ignition (Ornebjerg et al, 2006).The Incineration of MSW produces flue gases such as Carbon Dioxide (CO2), CarbonMonoxide (CO), Particulate Matter (PM), HCl, SulphurDioxide (SO2), Nitrogen Oxide (NO), total organic carbon, Hg and its compounds (Alba et al, 1997; Quinaa et al, 2008)
Collection Efficiency of ESP has been analyzed based on the concentration of particles and found that high efficiency is achieved when inlet particle concentration ranges from 200mg/Nm3 to 3600mg/Nm3 (Arif et al, 2018).A wet dust removal system (WDRS) has been developed by using wet phase transition agglomerator (WPTA) and wet electrostatic precipitator (WESP)
Summary
Municipal Solid Waste (MSW) Management, a decisive factor in the direction of sustainable urban growth, includes characterization, storage, treatment, segregation, collection, and disposal of solid waste to reduce its harmful impact on the atmosphere (Kumar et al, 2009). There are two ways of increasing the collection efficiency of ESP are (i) increase the dust particle migration velocity by maximizing the electric field strength around the discharge electrode (ii) by decreasing the gas flow rate (Octavian Blejan et al, 2007).The corona discharge electrode ESP is suitable to remove diesel exhaust particles Still, it has low filtration efficiency for Nitrogen Oxide (NO). The results clearly indicate that 100% collection efficiency has been achieved with the particles larger than 400 nm (Intra et al, 2014). considering the above facts, the intention of this paper is to design a cost-effective Photo-Voltaic powered Needle-plate Electrostatic Precipitator with dimensions (900mm*250mm)to filter the fine dust particles and smoke from flue gases produced by incineration of MSW
