Baghouse dust collectors are a type of dry dust removal device. After a period of use, due to effects such as sieve filtration, 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 subsequent operation, the initial layer becomes the main filtering layer of the filter material. Relying on the initial layer's function, filter materials with larger pores can 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 the two sides of the filter material is significant, some fine dust particles that have already adhered 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 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 thickens continuously, and the resistance value of the fabric dust collector also increases; upon the pulse valve diaphragm issuing a command, the pulse valve opens when it is submerged from both sides, the compressed air inside the high-pressure air bag is released. If there is no dust left or it is reduced to a certain degree, 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 (dust bin), cleaning system, and dust 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.
