Filter bag is the key part for bag filter operation process, normally the cylinder shaped bags are vertically hanging inside of bag filter. For impulse bag filter, dust is attached to outside surface of bag, when the dusty gas go through bag filter, dust is collected and gathered on the outer surface of bag, and clean air goes through bag and exhaust open air. The bag cage is inside bag for supporting. It can preventing bag fall down. And it also can use to clean dust cake and re-distribution.
Structure
Filter material use fiber, which has cotton fiber, wool fiber, synthetic fiber and glass fiber etc.
Application: Bag filter
Features
1. Normal filter material is 208 and 901 dacron, its operation temperature does not exceed 120℃, however, operation temperature of glass fiber bag is not more than 250℃.
2. Cotton fabric normally used for dusty gas without corrosivity and temperature below 80-90℃.
