CONSTRUCTION:
The Pulse Jet Bag Filter consists of a bag house comprising of filter bags with the supporting cages, venturies, hopper for the collection of the dust, header, air distribution pipes, pulse valves and centrifugal fan.
WORKING PRINCIPLE:
The dust laden air enters the PulseJet Filter at the dirty air plenum where it expands and the air velocity drops. This results in optimum air and dust distribution. Heavy particles are collected in the hopper of the dirty air plenum
The dust laden air then passes through the filter media arranged parallelly, depositing the fine dust on the outside of the bags.
Each bag is regularly cleaned by a reverse jet of compressed air thereby enhancing the filtration efficiency and reducing pressure drop on account of dust accumulation on the bag surface. A timer activates the valves at pre determined intervals on a continuous cycle. A short burst of compressed air is released and injected by the jet tube into the filter pad. This causes a brief controlled inflation of the pad to dislodge the accumulated dust cake into the collection facility.
