SCRUBBER WITH MOVABLE NOZZLE Russian patent published in 2018 - IPC B01D47/06 

FIELD: water and air purification technology; instrument making.

SUBSTANCE: invention relates to wet dust collecting equipment. Scrubber with a movable nozzle, comprising a housing with nozzles for dusty and purified gas, irrigation nozzle device, a lower support distributor tray and an upper restricting plate made of resilient materials with vibrators mounted thereon, nozzle layer, a liquid trap and a slime discharge device are arranged therebetween, wherein the nozzle is made in the form of hollow spheres, on the spherical surface of which a screw groove is cut, or in the form of a screw line formed on a spherical surface and having in the section perpendicular to the screw line, profile like a circle, polygon, "Berl saddle" or "Itallox" saddle, or in the form of cylindrical rings, on the side surface of which a screw groove is cut, or in the form of a screw line formed on the cylindrical surface and having in the section perpendicular to the screw line, profile like a circle, polygon, "Berl saddle" or "Itallox" saddle,the irrigation device is made in the form of an acoustic nozzle for spraying liquids, each of which comprises a hollow body with a nozzle and a central core, body is provided with a channel for supplying liquid and comprises a coaxial, rigidly connected bushing with a nozzle fixed in its lower part and made in the form of a cylindrical two-stage bushing, which upper cylindrical stage is connected coaxial with it central cylindrical core by means of threaded connection, having a central hole and installed with annular gap relative to cylindrical bushing inner surface, wherein the annular gap is connected to at least three radial channels formed in a two-stage bushing connecting it to an annular cavity formed by the bushing inner surface and the upper cylindrical stage outer surface, wherein annular cavity is connected to the body fluid supply channel, to a central core, in its lower part, diffuser is rigidly connected, made in the form of truncated cone coaxial with the central hole of the core, and attached by its upper base to the base of the cylinder of the central core, and splitter is attached to truncated cone lower base by means of at least three pins and made in form of round end plate which edges are bent towards annular gap, and on the outer lateral surface of the truncated cone there are screw grooves, characterized in that in the nozzle divider that is attached to the lower base of the truncated cone by at least three pins and is made in the form of a round end plate whose edges are bent towards the annular gap, throttle opening is provided axisymmetrically to the central hole of the central core, and to a central core rigidly connected to the upper cylindrical stage of the two-stage nozzle bushing, outer solid diffuser is coaxially attached so that the exit section of the annular gap connected to at least three radial channels made in the two-stage nozzle bushing is not overlapped.

EFFECT: increased dust collection process efficiency and reliability.
