SCRUBBER WITH MOVABLE NOZZLE Russian patent published in 2018 - IPC B01D47/14 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to wet dust collecting equipment. Scrubber with a movable nozzle, containing a housing with branches for dusty and clean gas, an irrigation nozzle device, the lower support and distribution plate and the upper limiting plate made of resilient materials with vibrators mounted on them, nozzle layer, a liquid trap and a slime discharge device are arranged therebetween, the nozzle is made in the form of hollow balls, 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 a section in the section perpendicular to the helix, such as a circle, a polygon, a Berl saddle or an 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 a cylindrical surface and having a profile of the type of a circle, a polygon, in a section perpendicular to the screw line, Berl saddle or itallox saddle, the irrigation device is made in the form of an injector with a screw conical swirl containing a body, and coaxially located and rigidly connected to it in the upper part of the fitting with an inlet cylindrical hole connected to the diffuser, which is axially symmetric in the housing, on the cut-out of which is located a perforated disk, and in the lower part of the housing is located axially symmetrical to housing a nozzle with at least three projections centering it in axial cylindrical chamber, the nozzle is made with a central hole on inner surface of which a screw thread is made, and between the perforated disk and the nozzle is placed a hollow screw-shaped coniform swirl nozzle with a screw thread, and the nozzle is pressed against the nozzle housing by a threading bead with a central confuser.

EFFECT: increase the efficiency and reliability of the dust collection process by increasing the degree of spraying of the irrigation device.
