Description
Technical field
The utility model relates to a kind of cooling tower, especially relates to a kind of energy saving and environment friendly spray filled cooling tower of Blower-free.
Background technology
At present, the domestic and international major equipment for circulating water is cooling tower, driving draught fan impeller to rotate the mode getting wind radiating and cooling is adopt mechanical transmission, and its mechanical drive has: electric motor, water turbine, speed reduction unit, blower fan (impeller) form. mainly can being divided into reverse-flow and cross flow cooling tower from the direction of water and air current flow, can be divided into square, rectangle profile, square be mainly used in adverse currentcooling tower, rectangle is mainly in cross flow cooling tower. tubular type water distribution, disc type (pool) water distribution, groove formula water distribution etc. can be divided into several from water distribution manner. cooling tower carries out work according to water and air contact heat exchange and transpiration cooling principle, its ultimate principle is that hot water enters the water-distributing device on cooling tower top by upper water pipe, then, hot water passes through the even splash of water-distributing device on water-sprayed filler sheet, hot water flows downward along filler sheet surface, the surface that water-sprayed filler sheet is concavo-convex is formed uniform water film, under the effect that freezing air rotates at draught fan impeller, being sucked from blast inlet enters in tower, space through filler sheet, heat exchange is carried out with the water film on filler sheet, absorb the heat in water film, simultaneously, due to the suction function in tower, part water is evaporated, thus the heat in water is taken away, finally discharge outside tower, it is melt in air, the hot water being pulled away heat is cooled, the bottom being finally pooled to cooling tower is catchmented in basin (pond), enter the equipment needing cooling, prepare circulation next time.
In adverse currentcooling tower, current and air-flow are countercurrent flow, namely air-flow enters then to turn to from cooling tower bottom blast inlet and flows vertically upward, and hot water disperses downward splash from top water-distributing device, flowing to drench after water packing and cold air stream carry out heat exchange and fall into the basin that catchments (pond), square counter flow cooling tower generally adopts tubular type water distribution mode to carry out the water that distributes, and shower nozzle is distributed on water distributor, hot water goes out through the downward splash of shower nozzle, and spray is drenched and drenched on water packing. In cross flow cooling tower, current become vertical direction to flow with air-flow, namely air-flow enters from the blast inlet of cooling tower both sides, along horizontal direction through filler, and hot water flows out from the nozzle (or aperture) of the water distribution tray bottom of top of tower, vertical uniform spray is drenched and is being drenched on water packing, the cold air stream with level process that flows downward carries out heat exchange, the air-flow absorbing heat is aspirated by draught fan impeller and discharges outside tower, hot water has distributed heat and has cooled and become cold water and fall into the basin that catchments (pond), enters the equipment needing cooling; These two kinds of cooling towers are current domestic and international application cooling apparatuss the most widely.
At present for the cooling apparatus of circulating water cooling system, also Blower-free is had to use without the cooling tower of motor, existing problems have waft that water loss rate is bigger than normal, noise is bigger than normal, the water yield of nozzle ejection, water curtain, water smoke, water spray height unequal, it is less than normal that extraneous air-flow enters amount in tower, heat exchanger effectiveness is low, and same thermal performance is on the low side.
Along with society and economic development, the life of people and the requirement of Working environment quality are also along with lifting, and people are more and more higher to saving water resource, the protection of conservation of power resources and environment, cry that is quiet and life safety of living.
Practical novel content
The purpose of this utility model is to provide a kind of mechanical power-driven gear, without electrical equipment device, unpowered energy consumption, noise is extremely low, water loss rate of wafing is the extremely low energy saving and environment friendly spray filled cooling tower of Blower-free.
For solving the problem, technical solution adopted in the utility model is:
