Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a multi-stage combined new bag filter. Background Art

[0002] A bag filter is a device that can effectively filter dust in the air, so it is widely used in environments with a lot of dust such as factories. Its filtering principle is to blow the dusty air into the interior of the dust collector at high speed through devices such as a fan, and then filter the dusty air through multiple filter bags.

[0003] When too much dust accumulates on the surface of the filter bag, the filtering effect will deteriorate. In the existing technology, when cleaning the filter bag, the common method is to spray high-pressure air into the filter bag, and use the impact of the high-pressure air and the vibration of the filter bag to make the dust attached to the surface of the filter bag fall off. This method can effectively remove the dust, but it will also accelerate the consumption of the service life of the filter bag. Content of the Utility Model
