Baghouse Pulse Jet FIlter

The most common type of dust collector system is called baghouse cleaning which is known as pressure-jet cleaning. In this mechanism dust is removed by high pressure blast of air. The blast that  enters the top of the bag tube, causes ceasing the flow of dirty air temporarily . The shock of air causes a wave of expansion to travel down the fabric. The flexing of the bag shatters and discharges the dust cake. The air burst is about 0.1 second and it takes about 0.5 seconds for the shock wave to travel down the length of the bag. Due to its rapid release, the blast of air does not interfere with contaminated gas flow. Therefore, pulse-jet baghouses can operate continuously and are not usually compartmentalized
