Combustion device for fine particles in exhaust gas

Abstract

Abstract PURPOSE: To renew a filter for collection of fine particles in exhaust gas while using only one burner without difficulty by turning the flame switching valve for regenerating burner into operation in linkage with the exnaust route switching valve under regeneration of the filter. CONSTITUTION: Exhaust gas from a Diesel engine is led through a passage 6 and into the open side of parallelly arranged filter selector valves 5, 5' to be got rid of fine particles. When the filter 2 is in stoppage on its either side, a pin 20 on a lever 19 is operated and a shaft 10 is rotated to invert the open-closed positions of the selector valves 5, 5'. Thus the route of exhaust flow is chanbed over. Because a flame selector valve 17 is fixed to the shaft 10, the valve 17 also operates while the valve 5 is in operation to introduce the flame at a regenerating burner 15 installed at the end of the filter to that filter situated on the side with no exhaust gas flowing into. The burner 15 is mounted separably at the end of the filter. COPYRIGHT: (C)1982,JPO&Japio
