Description

Technical Field

[0001] The utility model relates to the technical field of filter bag cleaning, in particular to a split filter bag pulse dust collector. Background Art

[0002] The pulse bag dust collector is a dry dust collector suitable for capturing fine, dry, non-fibrous dust. The dust bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of the fiber fabric to filter the dust-containing gas. After the dust-containing gas enters the dust collector, large particles with high specific gravity will settle into the dust hopper below under the action of gravity, while the fine dust will be filtered out by the dust bag. When it is necessary to clean the dust on the bag, gas is sprayed into the bag to peel off the dust adhering to the bag and settle it into the dust hopper to complete the cleaning work. However, since fine dust often passes through the filter bag when it adheres, it adheres to both sides of the filter bag at the same time, and traditional equipment can only clean one side during cleaning, and the cleaning is not thorough. Therefore, those skilled in the art provide a split filter bag pulse dust collector to solve the problems raised in the above background technology. Utility Model Content
