Fabric Filters - How it works

1, Dust flows through filter/bags
2. Fabric does some filtering
3. As more dust accumulates it becomes more efficient because porosity decreases - responsible for high efficiency removal rates

2

Pros

1. High efficiency for small particles
2. Require low pressure drops
3. Can collect acidic acids & mercury
4. Operate at a wide variety of dust types

3

Cons

1. Require large floor areas
2. Potential for fire or explosion
3. Fabrics can be harmed by high temps
4.Require a lot of maintenance

4

Utilization

Power generation industries - power plants

5

Pore space

50-75um

6

Thread length

100-150um
