Bag filter is a widely used and early developed dust removal equipment with mature technology, suitable for capturing small, dry, and non fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and uses the filtering effect of fiber fabric to filter the dusty gas. When the dusty gas enters the bag filter, the large and heavy particles of dust settle down due to gravity and fall into the ash hopper. When the gas containing fine and small dust passes through the filter material, the dust is blocked and the gas is purified.

Advantage:

⑴ High dust removal efficiency, generally above 99%, with high classification efficiency for fine particle dust.

⑵ The range of air volume processing is wide.

⑶ Simple structure and convenient maintenance and operation.

On the premise of ensuring the same high dust removal efficiency, the cost is lower than that of electrostatic precipitators.

Safety precautions:

Special attention should be paid to taking measures to prevent combustion, explosion, and fire accidents in bag filters.
