Description

Technical Field

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

[0002] The filter cartridge dust collector is used in locations where dusty gases are generated during operation. The dusty gases enter from the air inlet of the dust collector and flow into the ash hopper under the action of the baffle. Under the action of inertia and the weight of the dust, coarser particles of dust fall directly into the ash hopper, and other lighter and finer dust is adsorbed on the outer surface of the filter cartridge with the air flow. The clean gas after filtration passes through the filter cartridge into the upper box and is discharged through the fan.

[0003] Cartridge dust collectors are widely used in dust control. The key technology for the renewal and recycling of filter cartridges lies in pulse back-blowing dust removal. Good dust cleaning can ensure the long-term stable operation of the machine, reduce the consumption of filter cartridges, improve the filtration efficiency, and extend the life of the filter cartridges; poor dust cleaning will cause excessive accumulation of dust on the surface of the filter cartridge, increase system resistance, increase energy consumption, and even cause damage to the filter cartridge material.

[0004] Traditional filter cartridge dust collectors have two cleaning and dust removal methods, one is high-pressure airflow backwashing, and the other is pulse airflow blowing. Practice shows that the former has the advantage of uniform airflow and the disadvantage of high air consumption; the latter has the advantage of low air consumption and the disadvantage of weak airflow. Therefore, when the filter cartridge is blown with pulse airflow, some dust may still remain on the filter cartridge. Utility Model Content
