Description

Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a pulse dust removal device. Background Art

[0002] In a pulse dust collector, dust-laden gas enters the dust collector through the air inlet and first encounters the inclined plate and baffle between the inlet and outlet. This causes the airflow to turn and flow into the ash hopper, where it slows down. Due to inertia, the coarse dust particles in the gas flow directly into the ash hopper, acting as a pre-dust collector. The airflow entering the ash hopper then turns upward and passes through the metal-framed filter bags, where dust is captured on the outer surfaces of the bags. The purified gas then enters the clean room above the bag chamber and is discharged through the air outlet.

[0003] After the existing pulse bag dust removal equipment is used, a large amount of dust is still attached to the inner wall of the shell, which is difficult to clean. The dust accumulation affects the next use of the device. In addition, the filter bag needs to be replaced after a period of use, but the disassembly process of the device is cumbersome, resulting in a large workload for the staff. Utility Model Content
