Bag Filter House

Bag House or Bag Filter House is equipment which houses filter bags. It has two compartments separated by filter bags in such a manner that any of air stream passes through one compartment to another, that has to pass through Fabric Bag. One compartment is connected to in stream of flue gases and another to the inlet of Blower. Energy on the particles is exerted by pressure difference of both the compartments and flow of gases is created by Blower. Pressure drop in Bag House will depend upon Dust particle accumulated on the surface of bag fabric and no. of we have Bag House in cyclonic shape as well Rectangular Shape. Cyclonic Shape gives added advantage of filtration through fabric filters as well cyclonic separation. It reduces loading on Fabric Filter Bags.
a cType of fabric depends upon particle and temperature. The filters retain particles larger than the mesh size. Air and most of the smaller particles flow through. Some of the smaller particles are retained due to interception and diffusion. The retained particles cause a reduction in the mesh size. The primary collection is on the layer of previously deposited particles. Pressure drop will depends upon no. of bags. Higher no. of bags higher the filtration area, so lesser pressure drop is exerted.
