Baghouse dust collectors are a type of dry dust removal device. After a period of use, due to effects such as screening, collision, retention, diffusion, and static electricity, a layer of dust accumulates on the surface of the filter bags, which is known as the initial layer. In the subsequent operation, the initial layer becomes the main filtering layer of the filter material. Relying on the initial layer's action, 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 correspondingly. When the pressure difference between the two sides of the filter material is very large, 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 when the resistance reaches a certain level. The initial layer should not be damaged during cleaning 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, causing the resistance value of the bag dust collector to increase. 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 bladder to flow through. If there is no more dust or it has 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 (dust hopper), cleaning system, and 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.
