FIELD: mechanical engineering, diesel engines; cleaning exhaust gases from harmful components and soot. SUBSTANCE: proposed catalytic converter has housing with double walls and thermal insulation in between, inner and outer cross partitions, end face covers, inlet and outlet branch pipes, flanges, catalytic filters, temperature compensators, and reactor. Reactor inner space is divided by partitions into several spaces one of which is designed for distribution of gas flow, the other, for cleaning gases by filters and the third one, for uniting flow of cleaned gases. Tube is fitted in partition between gas distribution spaces which is extension of intake branch pipe. Spring-loaded valve opening into pass-trough branch pipe is installed in end face portion of tube. Pass-through branch pipe is arranged in longitudinal partition between spaces of where gases are cleaned by filters, between cross partitions dividing gas flow distribution spaces, gas cleaning spaces and gas flow uniting spaces. Moreover, catalytic converter has houses on which cermet filters are secured. One part of filters contains high temperature catalysts, and other part, low temperature catalysts. Cermet filters can be made also in form of hollow cups with segment-shaped bottoms in cross section. Rotary tubular sector with port, measuring 0.48-0.50 of tube cross section and port, measuring 0.70-0.75 of tube cross section are located over entire length of tube installed in partition between gas flow distribution spaces. EFFECT: increased service life of catalytic converter, improved quality of exhaust gas cleaning from nitrogen oxides and decreased smoking and toxicity. |
