THE USE OF A VORTEX TUBE TO CONTROL RECIRCULATION AND ELECTRICAL CLEANING OF SOLID FRACTIONS AND TOXIC GASES FROM EXHAUST GASES OF INTERNAL COMBUSTION ENGINES

Abstract


This article presents a technical solution to the problem of cleaning the exhaust gases of a car. The composition of the main toxic gases in the exhaust gases of a diesel engine of an average car is given and the disadvantages of known methods for reducing the toxicity of exhaust gases of modern cars are indicated. The operation of a device for purifying automobile exhaust gases from particulate matter and toxic gases using a vortex tube (Ranque-Hilsch tube), in the energy chamber of which an electric filter is installed, is described. The article presents the calculation results: vortex tube design; exhaust gas flow rates in a vortex tube; the rate of drift of solid particles from a hot stream to a cold stream in a vortex tube energy separation chamber. A calculation was also made of the amount of heat for heating the air used to burn soot in a permeable particulate filter. The expected efficiency of the exhaust gas cleaning of the proposed device is based on the calculation and partially on the results of studies of other authors.
