AIR CLEANING PLANT Russian patent published in 2019 - IPC B01D47/05 B01D45/06 B01D45/16 B01D45/18 B01D5/00 

FIELD: food industry.

SUBSTANCE: invention relates to equipment for dust trapping and can be used in any branch of national economy where it is required to trap fine aerosols from air duct, in particular in food industry. Air cleaning plant contains compressor 1, compressed air humidifier 2, heater 3, different-temperature condensation chamber 4 and moisture separator 5 connected in series. Different-temperature condensation chamber consists of a housing, of the lower and upper bottoms with cleaned gas supply and discharge nipples arranged on the housing, wherein cold and hot walls with devices to provide temperature difference of their external surfaces forming gas channel for cleaned air are installed in the housing. Hot wall is made in the form of turns of cylindrical spiral, at that one part of cold wall is made in form of cooled wall of chamber housing, and other part of cold wall is made in form of cooled cylinder installed in central part of said spiral.

EFFECT: spiral organization of the cleaned flow increases its contact zone with the different-temperature chamber and creates vortex flows due to centrifugal forces and friction against walls of the different-temperature channel, which create additional conditions for contact and increase of condensing particles, which affects efficiency of the whole plant.
