KOCHETOV'S NOZZLE ELEMENT FOR SCRUBBER Russian patent published in 2013 - IPC B01D47/14 B01J19/30 

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. Note here that said cutouts close up to form "П"-like cutout. Lobes that result are bent toward ring axis. Note here that lobes are provided with bent flanges in direction perpendicular to ring axis. Similar lobes are spaced through 90 degrees from previous lobes. Said elements differ from known designs in that ring cylindrical surfaces with two cutouts made in direction parallel with generating lines of said surfaces and cutout in direction perpendicular to ring axis are perforated.

EFFECT: higher efficiency and reliability of dust separation.
