Description

Technical Field

[0001] The utility model relates to the technical field of bag filters, and more particularly to an anti-corrosion bag filter. Background Art

[0002] A bag filter is a device used to filter solid particles from gases or liquids. It typically consists of a housing, filter bags, and a cleaning system. Dust-laden gas or liquid enters the bag filter from the inlet. As it passes through the filter bags, solid particles are trapped on the outer surface of the bags, while clean gas or liquid passes through the bags and is discharged from the outlet. As filtration progresses, dust accumulates on the bags, increasing the resistance. When the resistance reaches a certain value, the cleaning system activates, removing the dust from the bags through blowing, vibrating, and other methods, allowing the bag filter to resume normal operation.

[0003] For example, the bag filter with the prior art announcement number CN215233049U has the advantages of long service life, high solid gas filtration efficiency, small size, and small footprint.

[0004] However, the above-mentioned prior art still has the following problems when in use: when the gas with high humidity enters the bag filter for filtration, moisture will remain inside the bag filter, causing corrosion of the filter bag and the inner wall of the bag filter, resulting in a shortened service life of the bag filter. Based on this, the utility model provides an anti-corrosion bag filter. Utility Model Content
