Problems solved by technology

[0003] Although there are some filters that can filter particulate matter at present, the filter itself has no regeneration function. After the filter is used for a long time, a large amount of filtered particulate matter will adhere to the filter screen of the filter, causing the filter holes on the filter screen to be blocked. This in turn causes the engine to degrade or not function properly and other methods must be used for filter regeneration

Abstract

The invention relates to the field of filtrating equipment, and provides a filter which can filter particulate matters and has a regeneration function, so as to purify air and improve the air quality. The employed technical solution is that the filter comprises a housing, a metal fiber felt filter element and an electrode connecting part, wherein a flow through hole penetrating both ends is formed in the housing; at least one part of the metal fiber felt filter element is disposed in the flow through hole; the metal fiber felt filter element is matched with the hole wall of the flow through hole in a circumferential sealing manner; the part of the metal fiber felt filter element disposed in the flow through hole is taken as a first part; at least part of the first part is bent along a trajectory in the first direction to form a layered bending structure; a groove is formed between two adjacent layers of the layered bending structure; an opening of the groove is opposite to the opening in one end of the flow through hole; the electrode connecting part comprises at least one positive electrode connecting part and at least one negative electrode connecting part; the positive electrode connecting part and the negative electrode connecting part are electrically connected with the metal fiber felt filter element.

Description

technical field [0001] The invention relates to the technical field of filter equipment, in particular to a filter. Background technique [0002] With the rapid development of the economy and the remarkable improvement of people's living standards, the sales of motor vehicles in our country have increased rapidly, and the pollutants emitted by motor vehicle exhaust have increased significantly, causing serious pollution to the air in cities. Among them, the exhaust gas emitted by motor vehicles contains a large amount of particulate matter. How to effectively filter out these exhaust particulate matter is an important link in the process of vehicle exhaust gas treatment. [0003] Although there are some filters that can filter particulate matter at present, the filter itself has no regeneration function. After the filter is used for a long time, a large amount of filtered particulate matter will adhere to the filter screen of the filter, causing the filter holes on the filte...
