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 comprises compressor 1, compressed air humidifier 2, heater 3, different-temperature condensation chamber 4 and moisture separator 5 connected in series. Multi-temperature condensation chamber consists of a housing, a lower and upper bottoms with pipes for supply and discharge of cleaned air, arranged on the housing, wherein in housing there are cold and hot walls with devices for providing temperature difference of their outer surfaces, forming gas duct for cleaned air, which is made in form of turns of cylindrical spiral, wherein cold wall is made in form of cooled wall of housing of chamber, and hot wall is made in form of heated 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.
