SCRUBBER WITH MOVING NOZZLE Russian patent published in 2014 - IPC B01D47/06 

FIELD: process engineering.

SUBSTANCE: invention relates to dust separation equipment. Proposed scrubber comprises casing with dusty and purified gas pipes, sprayer composed by manifold with nozzles, bottom bearing-distributing tray and top limiting tray. Packed-bed layer, liquid trap and slime discharge device are arranged there between. Vibrator is arranged on top and bottom plates. Every nozzle comprises hollow and axially symmetric case. Straightener is arranged in the nozzle on manifold pipe through hole side. Said straightener is composed of ring with central sleeve and three vanes secured thereto and connected with the case. Conical orifice communicated with mixing chamber is made at nozzle case bottom. Mixing chamber is arranged between said orifice and straightener. Mixing chamber inner surface has screw-like grooves. Two hemispherical surfaces are secured in opposition to side surface of said ring to make hemisphere centre plane comply with top and bottom bases of cylindrical ring. Peaks of said hemispherical surfaces are located at ring axis and directed toward each other.

EFFECT: higher efficiency and reliability of dust separation.
