[0002] In the fields of petroleum, chemical industry, medicine, etc., dust and smoke are inevitably generated during the production process. Dust removal is to separate the dust generated during production from the smoke. The working principle of the bag filter dust collector is as follows: the dust-containing gas enters the filter chamber from the lower open flange, and the coarser particles fall directly into the ash bin. The dust-containing gas is filtered by the filter element, and the dust is retained on the surface of the filter element. The clean gas goes to the clean air chamber through the bag mouth and is discharged into the atmosphere. The existing bag filter bag cleaning device (Announcement No.: CN217526744U) has the following disadvantages in use:

[0003] During use, dust is filtered through the limiting grille and the filter bag. After filtration, the dust remaining on the surface of the filter belt is cleaned by blowing air through the pulse nozzle. However, the position of the pulse nozzle is fixed during cleaning, which makes it difficult to clean the filter belt away from the pulse nozzle. For this reason, this patent proposes a bag dust collector with a high-efficiency cleaning structure to solve the above problem. Utility Model Content
