A bag dust collector is a dry dust removal device. After a period of use, due to effects such as screening, collision, retention, diffusion, and electrostatic forces, a layer of dust accumulates on the surface of the filter bag, which is known as 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 still 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 there is a significant pressure difference between the two sides of the filter material, some fine dust particles that have already attached to the filter material may 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 promptly once the resistance reaches a certain level. During 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 continuously thickens, causing the resistance value of the bag dust collector to increase. Upon receiving the command, the diaphragm of the pulse valve opens when it is submerged on both sides, allowing compressed air from the high-pressure air chamber 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 (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 bag dust collectors and is an important aspect of their operation.
