BAG FILTER - DEDUSTING PLANT OPERATING

Many industrial manufacturing processes generate waste dust which is harmful for the operators.
Before being released into the atmosphere, the dust must be filtered through special systems commonly called air filters.
The drawing on the left shows a bag filter as an example.
The dusty air coming from processing is suctioned from entrance 1.
After filtration, the clean air is expelled through fan 6 into atmosphere 7.
During the system operation, on the filtering surfaces 4 settles the filtered material.
Such material is removed using special shots of compressed air.
The shots cause the shaking of surfaces 5 causing the fall by gravity of the filtered materials, discharged from the cochlea 8.
The jets of compressed air are generated in a cyclic manner from the control device A by impulses that open the solenoid valves E. The opening of each solenoid valve (cleaning cycle) determines the passage of compressed air from the tank 3 towards the inner part of the filtering surfaces.
It is possible to activate the cleaning cycle automatically using the differential pressure control between points P1, P2 which varies depending on the degree of clogging of the filtering surfaces.
By TC you can control both the broken bags or the increase of dust emissions.
