It is an air pollution control equipment comprising of dust collector that removes particulates or gas released from industrial processes out of the air. Power plants, cement factories, steel mills, pharmaceutical producers, food manufacturers, chemical producers and other industrial companies often use baghouses to control emission of air pollutants.
Dust-laden gas or air enters the baghouse through hoppers and is directed into the dust-collection chamber. 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. Finer particles entrained in the exhaust gas stream are collected in the filters for subsequent treatment / disposal.
When a sufficient pressure drop (ΔP) 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.
