Abstract: FIELD: machine engineering. 
     SUBSTANCE: bubbling-vortex device with the parabolic swirler nozzle for wet gas cleaning contains the cylindrical chamber with the inlet pipe, the slurry overflow pipe into the slurry tank, the axial sprinkler, perforated along its entire length by the small diameter holes and blinded from the outlet end. The cylindrical chamber is equipped with the pair of swirlers, installed in series, the first swirler along the gas flow is rigidly fixed to the axial sprinkler, and the second swirler along the gas flow is made with the central hole and connected to the cylindrical chamber walls, forming the gap for the gas flow passing to the central zone of the device. The swirlers are made in the form of the elliptical paraboloid, the guide blades of which are curved along the helical surface and form the curvilinear converging ducts. At the same time, the cylindrical chamber is connected to the cyclone with the slope by means of flanges and the branch pipe of tangential entry into the cyclone. The rejection of dispersed particles is carried out by means of the slurry overflow pipe into the device slurry tank. The cyclone is made in the form of the wet dust collection device, and in the tangential inlet into the cyclone the liquid inlet with the nozzle for flushing of the mobile foam is installed, formed from the rotating gas-liquid flow. The annular sprinkler with at least three nozzles is installed in the upper part of the housing, in the cyclone, connected through the pipeline to the liquid inlet for flushing out of the formed mobile foam. The purified gas flows through the exhaust pipe of the cyclone, and the slurry - is from the cyclone into the hopper to collect therein, and then into the slurry tank. At that the annular sprinkler jet in the cyclone contains the hollow casing with the nozzle and central core, the casing is made with the channel for liquid supply and contains the coaxial rigidly connected with it the sleeve with nozzle fixed in its bottom part, the nozzle is made in the form of cylindrical two-step sleeve, the top cylindrical step is connected by means of the thread joint with the coaxial with it the central core, having the central hole and installed with annular clearance, relatively to the internal surface of the cylindrical sleeve. The annular clearance is connected to at least three radial channels, formed in the cylindrical two-step sleeve, connecting it to the annular cavity, formed by the inner surface of the sleeve and the outer surface of the upper cylindrical step. The annular cavity is connected to the casing channel to supply the liquid. The spraying gun is rigidly attached to the central core, at its lower part, and it is made in the form of the truncated cone coaxial to the central hole of the core and attached by its upper base to the central core cylinder base, and the splitter is attached to the lower base of the truncated cone by means of at least three spokes, which is made in the form of the end circular plate, the edges of which are bent toward the annular clearance. There are the spiral grooves on the outer lateral surface of the truncated cone. In the splitter, which is attached to the bottom base of the truncated cone by at least three spokes and is made as the round end plate, the edges of which are bent towards the annular clearance, the throttle opening is made axially symmetric to the central hole of the central core. 
     EFFECT: increase of the dust and gas cleaning efficiency due to the organization of the rotational motion of the dust and gas flow, more efficient use of centrifugal force and use as the second, the dust and gas cleaning wet phase of the wet dust collector at the outlet of the device, which generally makes it possible to improve the device efficiency and to improve the environmental protection.
