Why Ecokleen  Bag Filters?

Conventionally in a typical Dryer ,cyclone is installed as primary separating device followed by a bag filter. Ecokleens Cyclone cum bag Filters do away with two separate installations by combining actions of both .

A conventional installation of a cyclone followed by a rectangular bag filter has following disadvantages

o         Pressure drop is more ...... thus fan power and hence energy cost is increased.  
o         Space required is more – increasing civil and structural cost.  
o         Two point collection system – needs two separate packaging areas (more manpower), 
           or additional equipments (screw conveyor) to make it single point collection (more energy bill).

Realizing the above, Ecokleen has designed Cyclone cum Bag Filter that has very less pressure drop, requires less space, and has single point collection.

Working Principle of Bag Filter and Cyclone cum Bag Filter

1.  The dust-laden air enters the cyclone chamber.

2.  The dust /powder separates due to cyclonic action and then enters the bag filter chamber.

3.  The air is uniformly distributed avoiding channelling while the powder separated by cyclone slides down from sides.

4.  Initially a coat of material forms on the bags. Subsequently, the coat acts as the filtering medium.

5.  The dust is accumulated on filter elements while the air passes through the filter bags from outside to inside.

6.  The accumulated powder is dislodged from the bags by reverse pulsejet air intermittently.

7.  The dislodged powder falls on bottom cone and is discharged through powder discharge valves.

8.  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 powders/dust.
