FIELD: cooling of circulating water. ^ SUBSTANCE: the vertical eddy-type nozzle-draft cooling tower has an axial-flow fan with profiled blades twisting the air flow, housing in the form of a tube, water drops separator, tray for collection of water, filter, circulating pump, comb and nozzles for spraying of water inside the tube bulk. The tube is made vertical with a diameter equal to 400-1200 mm, and the air flow twisted by the fan at an angle equal to 30-60 deg to the tube generating line is fed to it from the bottom upwards, and water is injected to the counter-flow through the nozzles. The cooling tower is provided with a trap for collection of water film draining over the tube inner surface, in the bottom of the tube the fan body is positioned with a clearance in the trap. ^ EFFECT: enhanced heat exchange and mass transfer, improved compactness. ^ 2 cl, 4 dwg |
