VORTEX EVAPORATOR-CONDENSER Russian patent published in 2016 - IPC B01D1/22 

FIELD: machine building.

SUBSTANCE: invention relates to heat and mass transfer devices. Vortex evaporator-condenser, consisting of vertical cylindrical housing with cover and bottom, process unions, heat carrier feed and discharge chambers, cylindrical pipes equipped with fluid distributors and internal tubes, on whose surface there are through channels to side edges of which is tightly attached shaped plate installed in guides washers that form swirlers to provide rotary translation vapor (gas) arranged along height of cylindrical tubes, characterised by that under each swirler support washers are provided with channels for coolant draining, ratio of inner diameter of bearing disc d to cylindrical tube inner diameter D is equal to d/d=0.6-0.9, and in guide washers are made through shaped holes for gas (vapour) movement in axial direction, ratio of distance between two adjacent support washers L to rotary column height for gas-liquid layer H is equal to L/H  1 Η value is equal to H is height of gas-liquid layer, m, h is height of channels in swirler, m; φ-gas content (fraction of gas in liquid), D_st is diameter of cylindrical tube, m, R_zav is swirler radius, m, u_g is speed of gas in channels of swirler, m/s, m is weight of rotating water (liquid), kg.

EFFECT: technical result is high efficiency.
