Particulate matter collecting device

Abstract

The invention relates to the technical field of engine tail gas treatment, and discloses a particle collecting device which comprises a shell. An inlet and an outlet are formed in the shell; a filtering assembly is arranged in the shell and is configured to filter gas entering the shell from the inlet; the filtering assembly comprises a first end cover, a second end cover and multiple parallel filtering channels; openings are formed in the two ends of each filtering channel; every two adjacent filtering channels share one side wall and are communicated through multiple filtering through holes in the side walls; the first end cover and the second end cover are located at the two ends of the multiple filtering channels respectively; the first end cover and / or the second end cover can respectively adjust the opening degree of the openings corresponding to the multiple filtering channels so as to adjust the flow direction of gas in a filtering assembly, so that the gas blows off particulate matters blocked on the filtering channels, and the problem that the particulate matters block the filtering assembly after the filtering assembly is used for a period of time is solved; and the filtering assembly does not need to be disassembled and cleaned, so that operation is convenient, and the cleaning effect is good.

Description

technical field [0001] The invention relates to the technical field of engine exhaust gas treatment, in particular to a particulate matter collection device. Background technique [0002] During the driving process of traditional vehicles, more particles will be produced. These particles will affect human health on the one hand and pollute the environment on the other hand. For this reason, in the prior art, a particle collection device is often installed at the exhaust end of the engine To collect particulate matter in the exhaust gas. like figure 1 As shown, a common particle collection device mainly includes a plurality of filter channels 1', each filter channel 1' is open at one end and closed at one end, and two adjacent filter channels 1' share a side wall and pass through multiple filter channels 1' on the side wall. Two filter through-holes 11' are connected, so that the exhaust gas enters through the opening of one filter channel 1', is filtered through the filter...

AI Technical Summary

Problems solved by technology

Considering that most vehicles drive in congested urban areas all year round, it is difficult to meet the requirements of driving speed, so it is difficult to effectively solve the problem of blockage of the filter through hole 11'
