DEVICE FOR CLEANING AND RECOVERY OF OFF-GASES Russian patent published in 2013 - IPC B01D47/02 B05B1/34 

FIELD: process engineering.

SUBSTANCE: invention relates to ash collectors and may be used at thermal electric power stations. Proposed device comprises inlet and outlet pipes, casing and settling chamber with separation baffle. Inlet gas duct is equipped with water sprayer composed of a manifold with vortex nozzles. Heat exchanger composed of tubular coil is arranged at chamber bottom. Device incorporates moisture separator with tangential inlet. Every nozzle comprises case with swirling chamber and atomiser. Said case is composed of feed union with inlet for fluid from main line and cylindrical sleeve connected coaxially therewith, while atomiser composed of blind cylindrical insert with, at least, three tangential cylindrical orifices. Swirler face surface has axial conical and cylindrical throttling orifices. Radial-flow swirler is arranged in case cylindrical chamber to form annular cylindrical chamber to feed fluid to radial-flow swirler tangential fluid inlets and communicated with three chambers: conical, cylindrical and diffuser outlet chambers.

EFFECT: higher efficiency.
