MASS-TRANSFER HEAT EXCHANGER Russian patent published in 2003 - IPC

FIELD: direct-contact mass-transfer heat exchangers, applicable in the heat-power industry. SUBSTANCE: in the mass-transfer heat exchanger with operating nozzles, of which the liquid-jet nozzle relative to the steam-jet nozzle is shifter opposite the flow with formation of a dispersion chamber, the steam path in the area of the liquid-jet nozzle is provided with a additional dispersal nozzle, and the dispersion chamber is formed to shape a contraction with a subsequent cylindrical section connected to the mixing chamber. The steam path may be made in the form of two cylindrical cowlings introduced in one other with formation of an annular gap, the exit section of the outer cowling is oriented in the area of the liquid-jet nozzle with formation of a dispersal nozzle, and the exit section of the inner cowling is brought out to the mixing chamber with formation of an operating steam-jet nozzle. EFFECT: provided contact of liquid with steam in the optimum relation for the whole length of their companion movement, enhanced specific heat rating, enhanced efficiency of heat exchange mass transfer processes. 2 cl, 1 dwg
