- Recovery of particulate matter from exhaust gas is vital for any industry from two aspects.
- To avoid pollution problems.
- Recovery of finished product increasing the plant yield.
Working Principle of Bag Filter
- The dust-laden air enters the bag filter bustle.
- The air is uniformly distributed avoiding channeling.
- Initially a coat of material forms on the bags. Subsequently, the coat acts as the filtering medium.
- The dust is accumulated on filter elements while the air passes through the filter bags from outside to inside.
- The accumulated powder is dislodged from the bags by reverse pulse-jet air or by mechanical shaking intermittently. n The dislodged powder falls on bottom cone and is discharged through powder discharge valves.
- The dust free air is sucked by induced draft fan and is exhausted to atmosphere.
- Knockers are provided on conical portion especially for sticky/hygroscopic materials.
