Bag filter is an air pollution control device that removes particulates out of air or gas released from commercial processes or combustion for electricity generation where high collection efficiency required . Bag filter is used in bag house. Most baghouses use long, cylindrical bags (or tubes) made of woven or felted fabric as a filter medium. Dust-laden gas or air enters the baghouse through hoppers (large funnel-shaped containers used for storing and dispensing particulate) and is directed into the baghouse compartment. The gas is drawn through the bags, either on the inside or the outside depending on cleaning method, and a layer of dust accumulates on the filter media surface until air can no longer move through it. When sufficient pressure drop (delta P) occurs, the cleaning process begins. Cleaning can take place while the baghouse is online (filtering) or is offline (in isolation). When the compartment is clean, normal filtering resumes.
