[0002] With the continuous improvement of the industrial level of various industries, engine exhaust has become the main source of air pollution. At the same time, the exhaust will generate noise during the exhaust process, affecting the living experience of surrounding residents. Therefore, the engine exhaust needs to be purified before discharge. In recent years, the market has gradually begun to use dry purifiers to replace traditional water spray. Dry purifiers are also called particulate collectors. They are divided into ceramic filter elements and metal filter elements. The metal filter element is mainly surrounded by a folding fan-shaped metal filter. The exhaust flows from the outside to the inside of the filter element, and the by-products remain on the metal filter outside the filter element.

[0003] According to the patent CN220360898U, a laminated air purification filter element includes a filter element cylinder, a blind plate, a large sealing ring, a small sealing ring, a pressing piece and several metal filter sheets.

By stacking the metal filter discs on the outer surface of the filter element cylinder in a stacking manner, the filtration area can be increased. At the same time, the support of the side of the filter element can be improved. It is not easy to deform during use, and the metal filter discs are easy to replace, which has good practicality. The added large sealing ring and small sealing ring can further increase the sealing effect of the filter element when it is used. During use, the traditional method of letting the exhaust gas enter from the side of the metal filter disc has a poor filtering effect on the exhaust gas, and can only install metal filter discs of fixed size, which has poor applicability. Therefore, it is necessary to design a new technical solution to solve this problem. Utility Model Content
