REVERSE PULSE BAG FILTERS
The Reverse Pulse Bag Filter is a dust collector of simplistic design that combines high dust collection efficiency and low maintenance under the most arduous operating conditions. The bag filter operation is fully automatic, has no moving parts and all the controls are situated on the outside of the unit.
REVERSE PULSE BAG FILTER THEORY
Dust-laden air enters the bottom hopper section, directly onto an inlet air diffuser plate. This diffuser plate changes the direction of flow and reduces the velocity of the particles.
Lower velocities ensure primary drop-out of the heavier particles. The lighter particles move upward in the air stream and onto the external surfaces of the filter bags.
As the dust accumulates on the outside of the filter bags, periodic cleaning is accomplished by introducing a short burst of compressed air delivered through specially designed venturi mounted directly above each filter bag.
The clean air flows through the bag media to the clean air chamber and out to atmosphere.
Dust from the bags after a cleaning cycle falls in a “dust cake” form into the hopper from where it is discharged via a dust disposal system.
Only a fraction of the filter bags are cleaned at one time, under continuous flow through the collector at rated capacities.
The dust collector bags can be readily inspected, checked, maintained or replaced from the clean air plenum.
REVERSE PULSE BAG FILTER PRODUCTS
Reverse Pulse Bag Filters handle flow rates from 0,5 to 100 m³/sec. and enable economical collection of dust at high filter rates with collection efficiencies > 99,99 %.
Reverse Pulse Bag Filters have high collection efficiencies, maintained under variable operating conditions by the reverse pulse action, and can operate 24 h/day under arduous conditions.
