SCRUBBER Russian patent published in 2012 - IPC B01D47/06 

FIELD: process engineering.

SUBSTANCE: invention relates to wet dust separation and may be used in chemical, textile, light industries, etc, for dusty gas cleaning. Scrubber comprises housing with dusty and cleaned gas branch pipes, sprinkler, support grids with nozzle arranged there between, and sludge removing device. Nozzle is made up of cylindrical rings with their side surfaces provided with two cutouts directed parallel with cylindrical surface generatrix and one cutout directed perpendicular to ring axis. Note that said cutouts close to form "П"-shape cutout. Lobes that result are bent toward ring axis, Said lobes are provided with flange-like bends in made direction perpendicular to ring axis. Similar lobes are arranged spaced 90 degrees apart. Casing of every nozzle is made up of confuser-like outlet and restricting orifice aligned therewith. Swirling chamber is made up of cylindrical barrel. Inlet and restricting orifice are located perpendicular and tangentially to said swirling chamber. Nozzle insert is arranged aligned with said swirling chamber to house three restricting orifices located sequentially and coaxially, one with another and with swirling chamber cylindrical surface: tapered, cylindrical central and outlet orifices.

EFFECT: higher efficiency and reliability of dust separation.
