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

FIELD: manufacturing technology.

SUBSTANCE: invention relates to wet dust collecting equipment. Scrubber with a movable nozzle, comprising a housing with nozzles for dusty and clean gas, an irrigation device, a lower support plate and an upper restricting plate, between which is located the layer of the nozzle, the spraying water collector and the device for removing the slurry, the lower support and distribution and upper limiting plates and the nozzle are made of elastic materials, and on the lower support-distributive and upper limiting plates there are mounted vibrators, the nozzle is made in the form of hollow balls, on the spherical surface of which a screw groove is cut, or the nozzle is made in the form of a screw line formed on a spherical surface and having a section of a circle perpendicular to the helix, a type of a circle, a polygon, or the nozzle is made of resilient polymeric materials, composites and is produced by molding or sintering methods, characterized in that the irrigation device is in the form of an injector comprising a hollow body with a nozzle and a central core, the housing is provided with a channel for liquid supplying and contains a coaxial, rigidly coupled with housing bushing with a nozzle fixed in its lower part and made in the form of a cylindrical two-stage, 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 with housing fluid supply channel to the 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 by its upper base is attached to the central core cylinder base, and to the lower base of the truncated cone, by means of at least three spokes a splitter is attached, which is made in the form of an end circular plate whose edges are bent towards the annular gap, and on the outer side surface of the truncated cone there are screw grooves, the axial-symmetrical center hole of the central core is provided with a throttle opening, In this case, an external diffuser is coaxially attached to the hub rigidly connected to the body in its lower part, an internal perforated diffuser is coaxially attached in such a way that the outlet sections of the external and internal diffusers lie in the same plane.

EFFECT: increased dust collection process efficiency and reliability.
