SCRUBBER WITH MOVABLE ATTACHMENT Russian patent published in 2014 - IPC B01D47/06 

FIELD: machine building.

SUBSTANCE: scrubber with a movable attachment, comprising a body with nozzles for dusty and cleaned gas, an sprinkling nozzle device, a lower support-distributing plate and an upper limiting plate, made of elastic materials with vibrators installed on them, between which an attachment layer is placed, a liquid trap and a device for sludge discharge, at the same time the nozzle comprises a cylindrical hollow body with a channel for supply of liquid and a coaxial bushing rigidly connected to the body with a nozzle fixed in its lower part, made in the form of a cylindrical double-stage bushing, the upper cylindrical stage of which is connected by means of a threaded connection with a central core, comprising a cylindrical part and a coaxial hollow cone, installed with a circular gap relative to the inner surface of the cylindrical bushing, the circular gap is connected with three radial channels made in the double-stage bushing, connecting it with the circular cavity formed by the inner surface of the bushing and the outer surface of the upper cylindrical stage, besides, the circular cavity is connected with the channel of the body for supply of liquid. On inner surfaces of cylindrical throttling holes made on the side surface of the cone with axes lying in planes perpendicular to the axis of the cone, there are helical grooves.

EFFECT: efficiency and reliability of a process of dust catching by increased extent of sprinkling device spraying.
