一种车用颗粒捕集器的辅助再生装置

Auxiliary regenerator for vehicular particulate filters

Abstract

An auxiliary regenerator for vehicular particulate filters comprises a tail gas incoming pipe and a tail gas outgoing pipe; a particulate filter is provided; the inlet end of the particulate filter is communicated with the tail gas incoming pipe; the outlet end of the particulate filter is communicated with the tail gas outgoing pipe; two exhaust brake valves are disposed in the tail gas incoming pipe and the tail gas outgoing pipe, respectively; the side, close to the tail gas outgoing pipe, the top of the particulate filter is provided with a purging air pipe; the top of the particulate filter is communicated with an air reservoir through the purging air pipe; the side, close to the tail gas incoming pipe, of the bottom of the particulate filter is provided with a purging exhaust pipe; the bottom of the particulate filter is communicated with the bottom of a filter water tank through the purging exhaust pipe; the top of the filter water tank is communicated with the air through an inverted U shaped exhaust pipe. The auxiliary regenerator is simple in structure and low in manufacturing cost and is applicable to modifying the existing particulate filters and prolonging their service lives.
