Problems solved by technology

[0004] In the prior art, there is also a triboelectric particle trap that uses electrostatic interaction to absorb pollutant particles, which also has a good trapping effect on small particles, but the regeneration technology has yet to be perfected. When it is directly used in high-emission scenarios, the trap shorter lifespan

Abstract

An embodiment of the invention provides a particulate matter catching device and a tail gas purification system and belongs to the field of environmental governance. The particulate matter catching device comprises at least one first catcher module for physically filtering particulate matter and at least one second catcher module, and each second catcher module comprises a cavity and a plurality of vibration units, wherein the vibration units are located in the cavity and are used for generating static electricity through friction so as to adsorb particulate matter, which is not filtered out by the at least one catcher module, in gas passing through the cavity. Through the particulate matter catching device and the tail gas purification system, the particulate matter is caught more thoroughly, and the service life and the regeneration period are prolonged.

Description

technical field [0001] The invention relates to environmental treatment, in particular to a particle trapping device and a tail gas purification system. Background technique [0002] With the increasing number of motor vehicles, the pollution caused by the exhaust emissions of many equipment including motor vehicles is also becoming more and more serious, especially the smog weather produced under unfavorable weather conditions after being superimposed with other industrial waste gas pollution, It has seriously affected people's daily life and health. Pollution particles in smog, such as PM2.5 (particles with a diameter less than 2.5 microns), can have adverse effects on human health because they can enter the human respiratory tract and even enter the human blood. [0003] Therefore, environmental governance, especially the prevention and control of particulate matter in the atmosphere, is very important. As one of the main sources of air pollution, the trapping of pollut...
