Air Pollution Control Systems

Wet Scrubber

Wet scrubber is used for air pollution control. The principle of wet scrubbers is that the dust laden air or gas is brought in contact with fine droplets of scrubbing liquid which is usually water, in a high turbulent zone which is created in a ventury. Due to high velocity and high turbulence the fine dust in the air or gas gets mixed with the scrubber liquid and the air or gas becomes dust free.


Bag Filter

Bag filter is used as an efficient air pollution control system. Bag filter consists of a housing with multiple filter bags Bag Filter Air Pollution Control Systems Direct Fired Hot Air Generators (HAG) Indirect fired hot air generators are used to heat the air for processes where clean air is a necessity and the temperature of air is below 350oC. Indirect Fired Wet Scrubber or cartridges mounted in it. The filter bags or cartridges are made of material suitable for operating temperatures and products being handled.

The dust laden air or gas passes through the filter media and gets filtered. The mechanism to dislodge the dust adhering to the filters is either reverse pulse jet using compressed air/nitrogen or mechanical shaking using pneumatic cylinders. Fine particles having size as low as 0.1 microns can be filtered thus making it possible to achieve emission levels as low as below 10ppm.
