Description

Technical Field

[0001] The utility model relates to the technical field of pulse dust filters, in particular to a pulse dust filter with a filter screen that can be quickly replaced. Background Art

[0002] Pulse dust filters are highly efficient dust removal devices that utilize pulsed airflow for dust removal and are widely used in various industrial gas purification systems. Pulse dust collectors generally consist of filter bags, chamber walls, a blower system, and a dust cleaning system. Their operating principle is as follows: Gas enters the dust collector through an intake duct, where attached dust is intercepted and deposited on the filter bags. Clean gas then passes through the bags and is discharged. When a certain amount of dust accumulates on the filter bags, the blower system releases a high-speed airflow, flushing as much of the dust from the bags as possible onto the chamber walls or chutes. The dust is then removed by the dust cleaning system, restoring the filter bags to their original filtering effectiveness.

[0003] When replacing the filter of a pulse dust filter, the filter cartridges containing the filter need to be removed one by one. The installation and removal of the filter cartridges of some pulse dust filters are more troublesome, which results in a lot of time being spent in removing the filter cartridges one by one, resulting in low efficiency in removing and replacing the filter.
