TO THE THEORY OF STRENGTH OF DIESEL ENGINE EXHAUST GAS PURIFICATION OF SOOT PARTICLES
Description
The problem of environmental protection from the contamination by toxic products, contained in the exhaust gases, is one of the most topical in the modern world. Nitrogen oxides and soot particles are the most toxic. Getting into the environment and the human body, they cause heavy chronic disease and significantly impair the quality of animal and plant products. The developed gas purification system SCR, the technology of plasma purification of exhaust gases have not found wide practical applications because of their high value. The study of papers dedicated to reducing exhaust gas toxicity shows that the use of combined means of purification, which usually include mechanical, thermal and catalytic methods of purification, is the most effective. Our work deals with the issue of purifying the diesel engine exhaust from fine particulate matter resulting in the combustion of fuel and oil motor partly. The article notes that the carbon is not magnetic, so the use of a magnetic field acting as an agent for the purification of exhaust gas from the carbon soot particles is impossible. The purification in a centrifugal field requires the creation of structurally complex centrifuges, so it is ineffective. We consider the possibility of purifying the exhaust gases from the soot particles in the electrostatic field. The device presents the collecting electrode, which is shaped as a cylinder, and an axial central electrode, which is mounted on an insulated spacer within the cylindrical body. The study deals with the physical and mathematical simulation of processes occurring in the proposed device of the purification of exhaust gases. The equality of the Coulomb force and the Stoks force determines the magnitude of the electrostatic field strength that is necessary for the purification of exhaust gas from the soot particles. We have identified the desired length of the collecting electrode
