DIFFERENT-TEMPERATURE CONDENSATION CHAMBER 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. Proposed chamber comprises housing 1, bottom 13 and top 12 bottoms with feed pipes 10 and cleaned gas discharge pipes 11 arranged on housing 1. In housing 1 there installed are cold and hot walls with devices for providing temperature difference of their external surfaces, which form gas channel 2 for cleaned gas, which is made in the form of coils of cylindrical spiral 3, wherein cold wall is made in form of cooled wall 5 of housing 1 of chamber, and hot wall is made in form of heated cylinder 4 installed in central part of said spiral 3.

EFFECT: spiral arrangement of the cleaned flow facilitates increasing its contact zone with the temperature chamber and creation of vortex flows due to centrifugal forces and friction against the walls of the different-temperature channel, which create additional conditions for contact and increase of condensing particles.
