Back-flushing regeneration swirling flow catcher

一种反吹再生旋流捕集器

Abstract

本实用新型公开了一种反吹再生旋流捕集器,主要由外壳,三通电磁阀、T型进气口、二次捕集器电磁阀、二次静电捕集器、壁流式陶瓷过滤体、上游压力传感器,温度传感器、下游压力传感器、储气罐、气源、储气罐单向阀、电磁阀、车载电控单元ECU组成;其特征是三通电磁阀、二次捕集器电磁阀、储气罐单向阀、电磁阀等在车载电控单元ECU的控制下,在需要对捕集器进行反吹再生时,捕集器下游腔内形成均匀的旋流压力场,反吹再生气流将捕集的柴油机尾气颗粒物与壁流式捕集器进行分离,在逆向的反吹气流压力和车震作用下,壁流式捕集器中的颗粒物被吹往二次静电捕集器中,实现颗粒捕集器的再生。
The utility model discloses a back-flushing regeneration swirling flow catcher which mainly comprises a shell, a three-way electromagnetic valve, a T-type air inlet, a secondary catcher electromagnetic valve, a second electrostatic catcher, a wall flow type ceramic filter, an upstream pressure sensor, a temperature sensor, a downstream pressure sensor, an air storage tank, an air source, an air storage one-way valve, an electromagnetic calve and a vehicle-mounted electric control unit (ECU). The back-flushing regeneration swirling flow catcher is characterized in that when the three-way electromagnetic valve, the second catcher electromagnetic valve, the air storage tank one-way valve, the electromagnetic valve and the like need to carry out back-flushing regeneration on the catcher under the control of the vehicle-mounted electric control unit (ECU), a swirling flow pressure field is evenly formed in a downstream cavity of the catcher, back-flushing regeneration air flow separates caught diesel engine tail gas particles from the wall flow type catcher, particles in the wall flow type catcher are blown into the second electrostatic catcher under the action of reversing back-flushing air flow pressure and vehicle vibration, and regeneration of a particle catcher is achieved.
