DIFFERENT-TEMPERATURE CONDENSATION CHAMBER Russian patent published in 2019 - IPC B01D47/05 B01D45/06 B01D45/16 B01D45/18 B01D5/00 

FIELD: machine building.

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 and top bottoms with feed pipes 7, 13 and cleaned gas outlet 8, 14 arranged on housing 1. Note here that cold and hot walls with devices to provide temperature difference of their outer surfaces forming gas channel for cleaned gas are installed in housing 1. Cold and hot walls are made in the form of coils 5, 10 of double-threaded cylindrical spiral, at that on turns of one approach there installed are devices for its cooling, and on coils of the other approach there installed are devices for its heating. Spiral arrangement of cleaned flows increases their contact zone with different-temperature chamber and creation of vortex flows due to centrifugal forces and friction against walls of different-temperature channel, creating additional conditions for contact and increase of condensing particles, which provides more complete separation of condensate and mechanical impurities from the stream of gas to be cleaned.

EFFECT: proposed is different-temperature condensation chamber.
