ABSTRACT:
Apparatus is disclosed for achieving separation of particulate matter from a gas flow by interacting the gas flow with a water curtain within a contacting chamber. The gas flow enters the contacting chamber tangentially near the bottom thereof whereby it tends to spiral upwardly toward an exhaust opening at the top of the chamber. Means are provided to form a water curtain across the passage through which the gas flow enters the chamber whereby particulate matter such as dust carried in the gas flow is entrained by water droplets thereof. Above the area of the gas flow inlet passage, spaced-apart ring-like members are provided for disrupting the upwardly spiraling gas flow and forcing the flow away from the chamber's side wall. A chamber rinsing means is provided adjacent the upper end of the chamber for directing a rinsing water flow downwardly against the chamber side wall in a spiral flow countercurrent to the gas flow. Still another water inlet means may be provided at a central location in the chamber above the level of the gas inlet passage to direct a downward axial water spray in the direction of the lower end of the chamber. The chamber has a discharge opening at its lower end for discharging water with the collected particulate matter separated from the gas flow.
