Wet scrubbers are air pollution control systems designed to clean industrial exhaust streams of solid, liquid, and gas particles before they are released into the air. A fan draws or pushes a polluted exhaust stream through ductwork and into the wet scrubber system, where the exhaust stream encounters a water spray designed to trap larger pollutants and saturate the air current. The exhaust stream then passes through a packing medium, which traps pollutants absorbed in the water, and a mist eliminator, which separate the moist droplets from the exhaust stream through inertial impaction and mechanical impingement.
Wet Scrubber features:
- Shipped complete with an integral coated steel base. No special mounting is required – just connect the duct, the water and power supply, and the air scrubber unit is ready for operation. Includes installation and operating instructions.
- Strategically designed components help to make our units low-maintenance (i.e. quick opening access doors for easy inspection).
- Wet scrubbers may be supplied with water either directly from your supply or from an integral or remote recirculation system supplied with the scrubber.
- Parihar wet scrubber units come complete with fittings for the addition of chemical neutralizers, if required.
- A complete metering and pumping system is also available upon request.
Wet Scrubber Applications:
- Hyrochloric Acid Air Scrubbing
- Sulfuric Acid Air Scrubbing
- Acid Air Scrubbing
Wet Scrubbing Process:
After slowing the velocity of the process air, our fume scrubbers employ a series of stages to thoroughly filter impurities out of the contaminated air stream:
- Stage 1. Fumes are passed through a water spray, which removes larger particulate matter while also saturating the remaining air.
- Stage 2. Next, a non-clogging, polypropylene mass packing impinges the fumes, absorbing the contaminants which are carried away by wash water.
- Stage 3. Any remaining entrained water is eliminated through a series of PVC eliminator blades that provide four 30 degree changes in direction.
- Stage 4. (OPTIONAL) Some fumes, such as HCL, can form an aerosol or “acid fog” inside the wet scrubber vessel. A high efficiency composite mesh pad mist eliminator is installed on the outlet of the Fume Scrubber to eliminate this problem.
