Dust-laden gas enters the baghouse via an inlet entry. Clean air exits through the inside of the filter bags while the dust particles are collected on the outside of the filter bag surface. In a pulse jet baghouse, filter bags are cleaned by using high pressure compressed air. A support cage prevents filter bag collapse during filtration, and aids in the filter bag cleaning.
The greatest advantage of pulse jet baghouses is that the filter bags can be cleaned on-line without stopping or interrupting the air flow entering the baghouse.
