Reverse Pulse Bag FiltersOptimal solutions for Air Environmental Control
REVERSE PULSE BAG FILTER
Reverse Pulse Bag Filters handle flow rates from 0.5 to100 m3/s and enable economical collection of dust athigh filter rates with collection efficiencies >99.99 %.Reverse Pulse Bag Filters have high collection efficien-cies, maintained under variable operating conditions bythe reverse pulse action, and can operate 24 h/day underarduous conditions.The Reverse Pulse Bag Filter is fully-automated and self-cleaning, with no internal moving parts.The system ensures that all dust stays in the system, thusoptimising recovery and ensuring that the operation isnon-polluting to the environment.
The bag filter units are equipped with filter bags to suitthe application and epoxy coated bag retainers. Filter bag inspection is easy and replacement of the bagsis done from the clean-air side, minimising any risk to themaintenance staff.

HOW THE REVERSE PULSE BAG FILTERWORKS
The dust-laden air enters the bottom hopper section,directly onto an inlet air diffuser plate. This diffuser platechanges the direction of flow and reduces the velocity ofthe particles.Lower velocities ensure primary drop-out of the heavierparticles.The lighter particles move upward in the air stream andonto 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 speciallydesigned venturi mounted directly above each filter bag. The clean air flows through the bag media to the clean airchamber and out to atmosphere. Dust from the bags aftera cleaning cycle falls in a “dust cake” form into the hopperfrom 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 ratedcapacities.The dust collector bags can be readily inspected, checked,maintained or replaced from the clean air plenum.
