DEVICE FOR DRYING, CLEANING AND HEAT EXCHANGING PURPOSES Russian patent published in 2008 - IPC F24F3/14 F28D11/02 

FIELD: heating.

SUBSTANCE: invention is intended for gas drying, cleaning and heat exchanging and may be used for air ventilation and conditioning. Device is provided with shell, rotor with set of disks fixed to hollow shaft and a set of heat exchanging tubes arranged circumferentially along set of disks but at some distance from shaft, inlet and outlet nozzles. At full circle, rotor disk edges are represented in the form of blades directed either in parallel to disk radius or at ϕ - angle to disk radius and deflected to inter-disk space at tilting angle 0<α<180°. Blades are flat or deflected lengthwise and edgewise with permanent thickness or profiled shape in cross section. Distance b between disks is selected based on the following condition λ>1, λ=b (ω/ν)^0.5, where b - distance between dicks; ν - cinematic viscosity of gas; ω -cyclic rotation frequency of rotor. Rotor in shell is installed with clearance d, defined by condition 0<d/R<0.5, where d - clearance between shell and rotor disks; R - disk radius.

EFFECT: increase of device productivity by mass flow rate and heat exchange especially at low gas pressure and improvement of gas cleaning quality.
