A bag dust collector is a dry dust filtration device. After a period of use, due to effects such as screening, collision, adhesion, diffusion, and static electricity, a layer of dust accumulates on the surface of the filter bag, which is known as the initial layer. In subsequent operation, the initial layer becomes the main filtering layer of the filter material, allowing for high filtration efficiency even with larger mesh sizes. As dust accumulates on the filter material surface, both the efficiency and resistance of the dust collector increase correspondingly. When the pressure difference across the filter material is significant, some fine dust particles attached to the material may be forced through, reducing the efficiency of the dust collector. Additionally, an excessively high resistance in the dust collector can significantly decrease the air volume of the dust removal system. Therefore, it is necessary to clean the dust collector when the resistance reaches a certain level. The cleaning process should not damage the initial layer to prevent a drop in efficiency.

As the powder repeatedly adheres to the outer surface of the filter bag, the powder layer thickens continuously, and the resistance value of the bag dust collector also increases; the pulse valve diaphragm sends a command, the pulse valve opens when it is submerged from both sides, the compressed air in the high-pressure air cylinder is released, and 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 bag dust collector consists mainly of the upper housing, middle housing, lower housing (ash hopper), cleaning system, and ash discharge mechanism.
The performance of a bag dust collector is largely determined by the selection of the filter bag material, with the cleaning system playing a decisive role. For this reason, the cleaning method distinguishes the characteristics of bag dust collectors and is an important aspect of their operation.
