ABSTRACT:
An apparatus for the wet separation of foreign particles from contaminated air includes a closed vessel containing a predetermined level of liquid. A supply duct supplies contaminated air containing foreign particles into the vessel at a position above the predetermined level of liquid. A plurality of air pipes have upper ends directly connected to the supply duct and have lower ends that terminate in the liquid at positions below the predetermined level, such that the air pipes directly supply contaminated air from the supply duct into the liquid. The liquid removes the foreign particles from the air to form purified air. An air outlet discharges the purified air from the vessel at a position above the predetermined level of liquid. The bottom of the vessel is trough-shaped and inclines downwardly to a liquid outlet from which liquid having entrained therein foreign particles is removed from the vessel. At least one of the air pipes is positioned to terminate adjacent the liquid outlet and to emit air which agitates any foreign particles tending to settle on the bottom of the vessel adjacent the liquid outlet.
