A bag dust collector is a dry dust filtration device. After a period of use, due to effects such as sieve filtration, collision, retention, diffusion, and electrostatic forces, a layer of dust accumulates on the surface of the filter bags, which is called the initial layer. In the subsequent operation 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 also achieve high filtration efficiency. As dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase accordingly. When the pressure difference between both sides of the filter material is significant, some fine dust particles that have already adhered to the filter material will be extruded through, causing a decrease in the dust collector's efficiency. Additionally, an excessively high resistance in the dust collector can significantly reduce the air volume of the dust removal system. Therefore, it is necessary to clean the dust collector promptly once the resistance reaches a certain level. During cleaning, the initial layer must 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 continually thickens, and the resistance value of the bag dust collector increases accordingly; the pulse valve diaphragm issues a command, and the pulse valve opens when submerged from both sides. The compressed air inside the high-pressure air bladder is released. If there is no dust or it is reduced to a certain extent, the mechanical cleaning operation will cease.
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 is determined not only by the correct selection of filter bag material but also by the cleaning system, which plays a decisive role. Therefore, the cleaning method distinguishes the characteristics of the bag dust collector and is a crucial aspect of its operation.
