VENTURI SCRUBBER Russian patent published in 2015 - IPC B01D47/00 

FIELD: machine building.

SUBSTANCE: Venturi scrubber contains a confusor, manhole, diffuser, sprinkling system, knockout drum, in the confusor the spraying device is installed containing water pipeline made in form of two mutually perpendicular sections, one section is located axisymmetrically to the confusor, and at its end at manhole side the spraying system nozzle is installed, at that input hole with diameter d1 of the confusor and output hole with diameter d3 of the diffuser are connected respectively with supply and outflow pipelines, and diffuser output connected with the outflow pipeline is tangentially connected with the bottom part of the cylindrical casing of the straight-flow cyclone acting as knockout drum, at that axes of the diffuser and cyclone casing are mutually perpendicular, at that the bottom part of the cyclone casing is connected with the cone bunker for sludge drainage, and top part is connected with the cone chamber to remove the cleaned gas; spraying system nozzle contains casing with union rigidly connected with the casing coaxially located in the top part of the casing and having cylindrical hole for liquid supply connected with the diffuser axisymmetric to the casing and union, and sprayer is connected to the casing in its bottom part by means of three spokes; the sprayer is at right angle to the casing axis and is made in form of the perforated disk.

EFFECT: improved efficiency of gas purification from dust and chemical impurities.
