Abstract:
A wet scrubber for scrubbing from an airflow particles contained therein, comprising:a) an acceleration cone through which a discharge airflow passes and is accelerated, the acceleration cone having an inlet and an outlet and a curved inner peripheral wall surrounding a passage of decreasing cross-section from the inlet to the outlet, the inner peripheral wall having a surface on which liquid for capturing particles can run down from the edge of the inlet to the edge of the outlet;b) a mixing chamber, in communication with the acceleration cone, provided with an impingement pool for holding liquid, and having a surface below the outlet of the acceleration cone such that the discharge airflow is directed upon and impacts the liquid in the pool and mixes with this liquid in the pool and the liquid falling from the edge of the outlet;c) a vortex chamber, connected to and in communication with the mixing chamber, for causing the airflow and liquid mixture to circulate, the vortex chamber having a cylindrical shape with an inner wall surface connecting with the surface of the mixing chamber and on which liquid flows when the airflow and liquid mixture circulate; andd) a discharge volute in communication with the vortex chamber for discharging the airflow and liquid after deceleration thereof, and having an inner wall surface that communicates with the inner wall surface of the vortex chamber, and an enlarged discharge port.
