Bag dust collectors are a type of dry dust filtration device. After a period of use, the filter material accumulates a layer of dust on its surface due to effects such as screening, collision, retention, diffusion, and static electricity. This layer of dust is known as the initial layer. During subsequent operations, the initial layer becomes the primary filtering layer of the material, allowing larger-pored filter materials 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, some fine dust particles attached to the material may be pushed 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 promptly when the resistance reaches a certain level. The cleaning process should not damage the initial layer to avoid a decrease in efficiency.
Baghouse Dust Collector:
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 filter dust collector increases accordingly; the pulse valve diaphragm issues a command, and when submerged from both sides, the pulse valve opens, allowing compressed air from the high-pressure air bag to flow. 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, among other components.
The performance of a bag dust collector is largely determined by the choice of filter bag material, but the cleaning system plays a decisive role as well. Therefore, the cleaning method distinguishes the characteristics of bag dust collectors and is a crucial aspect of their operation.
