A bag dust collector is a dry dust removal device. After a period of use, due to effects like sieve filtration, collision, retention, diffusion, and static electricity, a layer of dust accumulates on the surface of the filter bag, which is called the initial layer. In the subsequent movement process, the initial layer becomes the main filtration layer of the filter material. Relying on the initial layer's function, filter materials with larger pores can achieve high filtration efficiency. As the dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase accordingly. When the pressure difference between the two sides of the filter material is too great, some fine dust particles attached to the filter material will be squeezed through, reducing the efficiency of the dust collector. Additionally, an excessively high resistance in the dust collector can significantly decrease 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. When cleaning, the initial layer should not be damaged to avoid 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 bag dust collector also increases; the pulse valve diaphragm issues a command, and the pulse valve opens when it is submerged from both sides. The compressed air in the high-pressure air tank 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 materials but also on the cleaning system, which plays a decisive role. Therefore, the cleaning method distinguishes the characteristics of the bag dust collector and is an important aspect of its operation.
