Abstract：
 This invention discloses a converse regenerating wall flow type metal net plate apparatus for collecting microparticle discharged by diesel vehicle. The composite metal plate masking filter layer inclined certain angles in outer shell, 'WW' type is formed through baffle. Extension room is set between air intake and the filter layer, the room is connected to scavenging valve and carbon smoke second collecting device. Pneumatic disc valve, blowback cavity and air compress air tank at one side of the gas outlet are connected to the shell. Waste gas discharged by the engine enters from collector intake, and particles in the waste gas are entrapped when it flows through 'WW' type composite metal shadow masking. Discharging back pressure ascends when the particles deposit to certain quantity, and the regenerating equipment starts to blow out the accumulative particles from filter, and the particles are second collected and burned in collector. The structure is simple, cost is low, purification effect and regeneration effect is good, life is long and a good product for generalization.
