DEVICE FOR CLEANING AND RECOVERY OF OFF-GASES Russian patent published in 2014 - IPC B01D47/02 

FIELD: process engineering.

SUBSTANCE: invention relates to ash catchers. Proposed device case with inlet and outlet pipes and settling chamber with separation baffle. Lower part of said baffle has lengthwise slots arranged at constant spacing. Device inlet gas duct is equipped with water sprayer composed of manifold with atomisers connected with screw pump communicated with tank for collection of water from settling chamber. It includes also heat exchanger composed of pipe coil and moisture separator with tangential inlet. Atomiser comprises cylindrical hollow case with fluid feed channel and coaxial sleeve rigidly coupled with said case and having nozzle secured at its bottom. Said nozzle is composed by cylindrical two-step sleeve, its top cylindrical step being thread-jointed to central core. Said central core is arranged with clearance relative to cylindrical sleeve central surface and is composed of cylindrical part with ball segment secured coaxially at its bottom part. Said ball segment has orifices their axes being parallel with atomiser case axis.

EFFECT: higher efficiency and reliability of dust separation.
