Reverse Pulse Bag Filters Optimal solutions for Air Environmental Control TENOVA is a worldwide supplier of advanced technologies, products and engineering services for the iron & steel and mining industries.
REVERSE PULSE BAG FILTER Reverse Pulse Bag Filters handle flow rates from 0.5 to 100 m 3 /s 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. The Reverse Pulse Bag Filter is fully-automated and selfcleaning, with no internal moving parts. The system ensures that all dust stays in the system, thus optimising recovery and ensuring that the operation is non-polluting to the environment. The bag filter units are equipped with filter bags to suit the application and epoxy coated bag retainers. Filter bag inspection is easy and replacement of the bags is done from the clean-air side, minimising any risk to the maintenance staff. TRACK RECORD Tenova TAKRAF has a track record of some 2,000 Reverse Pulse Bag Filter installations in southern Africa on a variety of applications and in many different industries.

HOW THE REVERSE PULSE BAG FILTER WORKS The 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 a 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.
