They have the advantages of high efficiency, flexibility, and simplicity, and are widely used in air purification in various fields.

[0003] For example, the bag filter disclosed in the utility model patent with application number 202321243694.2 represents a type of prior art whose main structure includes a dust collection port, a sealing gasket, a snap-fit ​​block, a baffle, and a three-way ball, etc. The dust collection is achieved by the cooperation of the dust collection port, sealing gasket, snap-fit ​​block, baffle, and three-way ball.

[0004] During the incineration of waste, the temperature of the flue gas is relatively high, and the flue gas may contain water vapor, which affects the dust removal effect of the filter bags. Utility Model Content
