Baghouse dust collectors are a dry dust removal device. They are suitable for capturing fine, dry, non-fibrous dust. The filter bags are made of woven fabric or non-woven felt, utilizing the filtering effect of the fiber fabric to filter dusty gases. When dusty gases enter the baghouse dust collector, particles with large size and high density settle down due to gravity, falling into the ash hopper. The gas containing finer dust is retained by the filter material during passage, resulting in the purification of the gas.
Baghouse dust collectors are a type of dry dust removal device. After a period of use, the filter material accumulates a layer of dust on its surface due to effects like screening, collision, retention, diffusion, and static electricity. This layer of dust 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, filter materials with larger pore sizes 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 too great, some fine dust particles attached to the filter material will be forced 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. When cleaning, the initial layer must be preserved to avoid a decrease in efficiency.
