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. Different-temperature condensation chamber includes housing 1, lower 15 and top 14 bottoms with branch pipes 12 and cleaned gas discharge branch pipes 13 installed on housing 1. In housing 1 there are cold and hot walls with devices to provide temperature difference of their external surfaces, which form gas channel 2 for cleaned gas. Hot wall is made in the form of turns of cylindrical spiral 3, at that one part of cold wall is made in form of cooled wall 5 of housing 1 of chamber, and other part of cold wall is made in form of cooled 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.
