DEVICE FOR GAS HEAT EXCHANGING, DRYING AND CLEANING PURPOSES Russian patent published in 2012 - IPC F24F3/14 

FIELD: heating.

SUBSTANCE: device for gas heat exchanging, drying and cleaning purposes refers to air ventilation and conditioning and can be used in air treatment devices installed in buildings and facilities of various purposes, and namely in domestic and public buildings, in stock buildings. Device includes housing with inlet and outlet connection pipes for treated gas, rotor with pack of discs with a central hollow channel for heat exchange, which passes through the whole pack of discs and is connected to atmosphere by means of inlet and outlet connection pipes. According to the invention, central heat exchange channel is formed with internal axisymmetrical outlines of discs, which are rigidly attached to each other and form a pack and annular inserts tightly mounted between them; at that, internal outlines of discs are shaped and have regularly variable configuration so that heat release surface area of each disc and channel as a whole is enlarged.

EFFECT: increasing heat exchange efficiency of discs using atmospheric air.
