Description

Technical Field

[0001] The utility model relates to the technical field of industrial dust removal, in particular to a pulse dust collector which is convenient for replacing filter bags. Background Art

[0002] In industrial production, in order to achieve green production, the waste gas generated in the production usually needs to be filtered and purified through a pulse dust collector, and the dust in the waste gas is filtered through filter bags before being discharged; commonly used pulse dust collectors include tube-spray pulse dust collectors and box-spray pulse dust collectors.

[0003] For example, Chinese patent CN219111090U discloses a box-type flat bag pulse jet dust collector cleaning device, which uses filter bags to block dust in the air flow on the outer wall of the filter bags, while the clean air passes through the filter bags, moves upward from the inside of the filter bags to the upper side of the perforated plate and is discharged from the air outlet; after a period of use, all filter bags are pulse-backblown through the nozzles on the box wall to clean up the dust attached to the outer wall of the filter bags.

[0004] However, when installing the filter bag, the top edge needs to be stuck on the inner wall of the circular hole on the perforated plate. During this process, the filter bag may fall off, and the outer wall of the filter bag will become hardened after a period of use, making it difficult to remove from the circular hole and difficult to replace the filter bag.

[0005] Based on this, the utility model designs a pulse dust collector which is convenient for replacing filter bags to solve the above problems. Utility Model Content
