KOCHETOV`S SCRUBBER Russian patent published in 2017 - IPC B01D47/06 B05B1/26 

FIELD: machine engineering.

SUBSTANCE: scrubber comprises of a body, consisting of a conical, cylindrical portions and a sludge tank, dusty gas inlet branch pipe, cleaned gas outlet branch pipe, spraying device including an external line with bottom and top atomizers in it. The atomizers are designed as nozzles. Each nozzle contains a hollow body with an atomizer and central core. The body is provided with a channel for supplying liquid and includes a coaxial bushing rigidly connected to it and an atomizer, fixed in its lower part, designed as a cylindrical two-stage bushing. The upper cylindrical stage of the bushing is connected to the coaxial central core via a threaded connection. The central core has a central hole and provided with an annular clearance to the inner surface of the cylindrical bushing. The annular clearance is connected to at least three radial channels formed in a two-stage bushing connecting it to an annular cavity formed by the inner surface of the bushing and the outer surface of the upper cylindrical stage. The annular cavity is connected to the channel of the body for supplying liquid. A spraying device in the form of a truncated cone is rigidly attached to the lower part of the central core and coaxial to the central hole of the core and attached by its upper base to the base of the central core cylinder. A splitter is attached to the lower base of the truncated cone by means of at least three spokes and is made in the form of an end circular plate the edges of which are bent toward the annular clearance. There are spiral grooves on the outer lateral surface of the truncated cone. A throttle opening is provided in the splitter axisymmetrically to the central hole of the central core. An external diffuser is coaxially attached to the lower part of the bushing, which is rigidly connected to the body. An inner perforated diffuser is coaxially attached to the lower base of the truncated cone of the spraying device in such a way that the outlet cross-sections of the external and internal diffusers lie in one plane.

EFFECT: higher efficiency and reliability of dust separation by increasing the liquid atomization level of nozzles.
