The utility model principle is as follows

From thermodynamic (al) angle, it is cold that parallel-counter flow jet flow duplex cooling tower and traditional adverse current filling cooling tower belong to wet type But tower, caloic when being mainly in direct contact by water and air, which exchanges, carries out heat transfer, and heat is transmitted to unsaturated air by water, Water temperature drop, air themperature is set to increase, water capacity increases, and is discharged into air.

By thermodynamic argument it is found that the temperature difference is the motive force of transmittance process, and the partial pressure force difference of vapor is then mass transter Motive force, evaporation and cooling, mass transter plays a leading role；Parallel-counter flow jet flow duplex cooling tower projects flow by ejector While, so that the cracking of water beam is refined into numerous small water droplets and increase with unsaturated air contact area, is penetrated in addition projecting water droplet It is set adequately to contact and perturb with air-flow to the kinetic energy of tower chamber, the caloic for being conducive to aqueous vapor exchanges, and accelerates water droplet cooling velocity, After water droplet fair current to the multidimensional shape water collection device of injection, adverse current to honeycomb, carries out secondary cold under gravity But collecting-tank is fallen into afterwards, so entire caloic exchange process not instead of conventional filler tower simple reverse-flow, fair current and adverse current Combination, tower intracavitary air-flow constantly perturb, increase the relative velocity of gas liquid interfacial area, the factor of these features is strong The heat exchange efficiency of parallel-counter flow jet flow duplex tower is changed.

When cooling tower is run, the saturated moist air in tower is mingled with numerous small water droplets, under the action of wind turbine, tiny water Drop is easy drift outside tower, quantity of circulating water is not only lost, but also influence ambient enviroment；The characteristics of multidimensional shape water collection device：Its composition of leading the way Unique hyperspace, ventilation resistance is small, is uniformly placed in below tower top fan platform, effectively controls wind turbine rotation and causes Vortex phenomenon, improve the destabilizing factor of tower intracavitary fluidised form, water rem oval is further enhanced.

The honeycomb is bonded hexagonal honeycomb shape structure by multiple knee-pieces, and air-flow is made to uniformly enter To tower chamber without generating vortex, the relative velocity of gas liquid interfacial area is increased, the water droplet that ejector sprays does not generate assembly, water Drop is uniformly distributed, and sufficient heat exchange is obtained with air.

The scroll casing type ejector includes upper volute, lower spiral case, nozzle, air inducing mouth, air-vent, water inlet composition, nozzle With water inlet position not on same vertical center line, water inlet offset nozzle center line, the aquatic products sprayed hence into nozzle Raw eddy flow makes the cracking of water beam be refined into numerous small water droplets；Nozzle is double-layer structure, and internal layer is water spout, and outer layer is air inducing mouth, Be provided with several air-vents on air inducing mouth peripheral wall, nozzle in course of injection around generate negative pressure, have the function of air inducing；Water is set to spray Heat exchange is fully carried out with unsaturated air during penetrating, to improve heat exchanger effectiveness；Due to the negative pressure that jet stream generates, auxiliary It is pumped into extraneous unsaturated air, so parallel-counter flow jet flow duplex cooling tower is compared with conventional counter-current filling cooling tower, identical work Under condition, the cold effect effect colder than adverse current filling cooling tower of parallel-counter flow jet flow duplex cooling tower is high.
