Air Pollution Control Scrubbers

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. The scrubber liquid is then separated from the air or gas in a droplet separator which has a tangential entry and uses the centrifugal force for separation. The secondary separation is done by passing the air or gas through demister pads. Provision for automatic flushing of demister pads is made using multiple spray nozzles above it. There a different variations available in scrubber design depending upon the concentration of dust in the air or gas and the permitted emission level. Technodry scrubbers are specially designed to handle the most critical emission norms with high efficiency and low operating cost.
