DEVICE TO CLEAN INCOMBUSTIBLE GASES Russian patent published in 2015 - IPC B03C3/16 B04C9/00 

FIELD: process engineering.

SUBSTANCE: invention relates to removal of dust or other disperse particles from gases and can be used in metallurgy, chemical industry, construction, etc. Proposed device comprises cyclone consisting of cylindrical case with conical bottom equipped with sludge discharge pipe, dusty gas flow feed pipe arranged tangentially to said case and cover with cleaned gas discharge pipe. Electrical filter consists of corona-forming electrodes arranged inside dusty gas flow feed pipe, corona-forming electrodes and/or electrodes/nozzles fitted at cyclone cylindrical case conical bottom. Conical gauze filter is arranged at cleaned gas flow pipe to make corona-forming electrode which is equipped with corona-forming needles. HV source negative pole is connected to corona-forming electrode inside dusty gas flow pipe and to conical gauze filter. HV source positive pole is connected to corona-forming electrodes, electrodes-nozzles arranged at cyclone conical bottom or cylindrical case.

EFFECT: higher quality of gas cleaning.
