Bag dust collectors are a type of dry dust removal device. After a period of use, due to effects like screening, collision, retention, diffusion, and electrostatic forces, a layer of dust accumulates on the surface of the filter bags. This layer is called the initial layer. In subsequent operations, the initial layer becomes the main filtering layer of the filter material, enabling filter materials with larger pores to achieve high filtration efficiency. As dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase correspondingly. When the pressure difference between the two sides of the filter material is significant, it can squeeze some fine dust particles that have already adhered to the filter material, causing the dust collector's efficiency to decline. Additionally, an excessively high resistance in the dust collector can significantly reduce the airflow in the dust removal system. Therefore, it is necessary to clean the dust collector in a timely manner once the resistance reaches a certain level. The cleaning process should not damage the initial layer to prevent a decrease in efficiency.

As the powder repeatedly adheres to the outer surface of the filter bag, the powder layer continues to thicken, and the resistance value of the fabric dust collector increases accordingly; the pulse valve diaphragm issues a command, and the pulse valve opens when submerged from both sides. The compressed air in the high-pressure air bag is released. If there is no dust or it is reduced to a certain extent, the mechanical cleaning process will stop.
Baghouse Dust Collector Product Structure:
The structure of the bag dust collector mainly consists of the upper housing, middle housing, lower housing (ash hopper), cleaning system, and ash discharge mechanism, etc.
The performance of a bag dust collector depends not only on the correct selection of filter bag material but also on the cleaning system, which plays a decisive role. For this reason, the cleaning method distinguishes the characteristics of bag dust collectors and is a crucial aspect of their operation.
