FEASIBILITY OF USING A HYDRO-CAVITATION MIXER IN AGRICULTURAL COMPLEXES

Abstract

At present, the issue of using water-fuel emulsions in order to improve the technical, economic and environmental characteristics of various objects is becoming increasingly relevant in agro-industrial complexes. This is especially true in relation to fuel oils, which are used to obtain thermal energy of medium and low power, which takes place in agro-industrial complexes. As a rule, fuel oil contains moisture, solid fractions, has an increased flash point and other deviations from the norms that violate the combustion regime, contaminate the heating surface, increase fuel underburning, and form deposits of unburned coke particles along the gas path.
 A complex solution to these problems can be the creation of a uniformly distributed fine fraction of the moisture present in fuel oil and the destruction of quasi-crystalline structures that are part of fuel oil using various types of statutory devices, which, in order to obtain cavitation bubbles of optimal size in terms of technological impact, generate a cavity with a certain nature of unsteady motion in its tail section, which unfortunately leads to the destructive effect of cavitation erosion of hydraulic system elements.
 The solution to the problem was based on the principle of using the hydrodynamic parameters of moving liquids to form fine emulsions of fuel oils of various grades using a special design developed based on a cavitation generator, which ensures the removal of collapsing cavitation bubbles to the center of the flow, which significantly minimizes cavitation erosion of hydraulic system elements, hydro cavitation mixer.
 The developed scheme of the hydro-cavitation mixer provides the principle of processing fuel oils with a four-stage technology, which leads to the full combustion of the water-oil emulsion and the reduction of emissions of carcinogenic substances into the atmosphere, an increase in the efficiency of boilers by 2,4% and provides 25% -30% fuel oil savings. As a dispersed phase, not only water can be used, but also liquid fuel waste, industrial water, or mixtures thereof, which reduces the cost of their disposal.
 The developed hydro cavitation mixer is of particular interest for agro-industrial complexes, since it can be used for pasteurization of food products using the “cold boiling” phenomena, provided that the cavitation generator is made from the appropriate material.
