In paint spray fume scrubbers, the fume is sucked through the ducts connected from paint spray room to the scrubber fume inlet. It flows upward through single stage scrubbing filters.
The contaminated air gets washed by spraying water from spray nozzles and separates the paint dust or fume. The air flows upward through multiple sections tangential set of vanes and flows out through the exhaust fan. Thus, it keeps the environment clean. The scrubbing liquor is fed by gravity from an inlet water pipe and avoids the need for blockage prone spray nozzles.
The water flows down to the distribution cone, which forms the lower face of the vane scrubbing assembly. The particulate laden gases enter the body of the scrubber tangentially allowing large particles to be collected in the lower section submersed in the water tank. The paint sludge floating on the water is cleaned through the inspection doors at least once daily. The paint sludge that is settled at the bottom of the water tank is cleaned by opening the drain plug at least once in a week (the time for removing the sludge may vary as per its usage).
