Flow-through particulate incineration system coupled to an aerodynamically regenerated particulate trap for diesel engine exhaust gas

A diesel engine exhaust gas filtration and incineration system for reducing total particulate emissions in diesel exhaust from a diesel engine comprising:

• a diesel engine exhaust gas conduit having a diesel exhaust inlet port couplable to a diesel engine and a diesel exhaust outlet port couplable to ambient;
• a regenerable particulate trap having pores sized to capture particles therewithin that are contained in the diesel exhaust, said filter disposed in said diesel engine exhaust conduit between said diesel exhaust inlet port and said diesel exhaust outlet port;
• a source of compressed air controllably coupled to said diesel engine exhaust gas conduit between said particulate trap and said diesel exhaust outlet port;
• a particulate incineration unit coupled to said diesel engine exhaust gas conduit between said particulate trap and said inlet port, said incineration unit comprising a burner and a filter, said filter comprising a generally cylindrical wall having pores sized to prevent passage of the particulates therethrough and permit passage of air therethrough, said wall further having a surface area sized to maintain a flow rate of air from said source of compressed air;
• and
• a controller, operatively coupled to said source of compressed air and operable in a filtration mode for coupling diesel exhaust in said diesel exhaust gas conduit through said particulate trap and directing filtered exhaust gas out said diesel exhaust output port, and further operable in a regeneration mode to provide at least one pulse of high pressure Air from said source of compressed air that flows through said particulate trap in a direction that dislodges soot (laden with PAH) and ash particles that are lodged within the pores thereof and that moves the soot (laden with PAH) and ash particles into said incineration unit.
