Background technology
Cooling tower is to carry out cold and hot exchange using the counter current contacting of water and air, to realize the dress of circulating water cooling
It sets.Mechanical-draft cooling tower introduces extraneous air by tower top wind turbine, after the cold air of rising and the hot water contacts of whereabouts, passes through
Two processes of evaporative heat loss and heat loss through convection realize circulating cooling water cooling by the cold air of the heat exchange of hot water to rising
But.
However, hot steam has also taken away part water to be cooled simultaneously, the loss for recycling water to be cooled is caused, needs constantly to mend
Filling fresh water maintains water to stablize, and operating cost is increased, moreover, because water evaporation causes cooling tower ambient humidity, light and temperature excessively high, no
It is maintained conducive to cooling tower.
In addition, the recycling and repetition of cooling water are cooling so that cooling water is contaminated serious, ability after processing is needed
It is continuing with.

Vapor is recycled, it is cost-effective.
To achieve the goals above, the technical scheme adopted by the utility model is that:
A kind of cooling tower, including tower body, the air duct above tower body and the water tank set on tower body bottom, wherein described
Once water collection device, spraying layer, packing layer and air-supply layer are sequentially distributed in tower body from top to bottom, the water tank bottom center is worn
There is water inlet pipe, the water inlet pipe sequentially passes through the air-supply layer and packing layer enters the spraying layer, and the water inlet pipe is located at institute
The top for stating spraying layer leads in divergent shape and has several water distributors outward, several rotations are evenly distributed on the water distributor
Spraying device, is equipped with secondary collection device at the top of the air duct, and the secondary collection device includes taper top from top to bottom and U-shaped
It is connected at the top of collecting tank, the U-shaped collection trench bottom and the air duct, gas outlet, the outlet is provided at the top of the taper top
Wind turbine is equipped in mouthful, the water tank side wall is equipped with overflow port, and the overflow port exit is equipped with strainer.
Further technical solution is:
The plane that the water distributor is constituted is vertical with the tower body side wall.
The direction of the rotary atomization device is upward.
The air-supply layer circumferential side wall is equipped with filter.
The air-supply layer is additionally provided with unhurried current plate, and the unhurried current plate is obliquely installed, the higher one end of the unhurried current plate with it is described
Filter is connected, and the water tank is stretched into the lower one end of the unhurried current plate.
The unhurried current plate surface is in wavy.
The tower body housing diameter of the spraying layer is gradually reduced from bottom to up.
Compared with the prior art, the utility model has the advantages that:(1)The utility model uses spraying device simultaneously
It is cooled down twice with mechanical ventilation, accelerates cooling efficiency, while the two is superimposed use up and down, also improves space utilization
Rate;(2)The tower body shell of spraying layer gradually tapers up so that the quickening of the tower body interior air-flow rate of climb, has further speeded up cooling efficiency
;(3)Using rotary sprayer, make water atomization degree higher to be cooled, convenient for cooling;(4)Water collection device and secondary collection dress
The setting set enables vapor high efficiente callback, reduces moisture loss, wherein in secondary collection device, U-shaped collection channel opening by
Gradually so that air-flow rising slows down, taper top then plays the role of condensation for amplification;(5)Wavy unhurried current plate is set, cooling is slowed down
Water falls into the speed of sink, while cooling water being made to fall into the position of sink far from tower body side wall, to reduce sink as far as possible
The flowing of interior cooling water keeps the deposition of dirt effect that it is included more preferable, using the strainer filtering at overflow port, ensures that
The cleanliness factor of cooling water.

Specific implementation mode
To keep the purpose of this utility model, structure and advantage clearer, below in conjunction with attached drawing to the utility model reality
The mode of applying is described in further detail.
As Figure 1-Figure 2, a kind of cooling tower, tower body 1 are sequentially distributed once water collection device 17, spraying from top to bottom
Layer, packing layer 3 and air-supply layer.1 bottom of tower body is equipped with sink 7.7 bottom of sink is equipped with multiple pillars 16.7 bottom center of sink is worn
Equipped with water inlet pipe 4, water inlet pipe 4 sequentially passes through air-supply layer from tower body bottom and packing layer enters spraying layer.If its top, which is led to, to be had
Dry water distributor 5, these water distributors 5 are in approximately the same plane, and vertical with water inlet pipe.In the embodiment of fig. 2, six roots of sensation water distribution
The annular array on water inlet pipe circumference of pipe 5, meanwhile, it is uniformly distributed on every water distributor there are three rotary atomization device 6, these rotations
The spout for turning spraying device is arranged upward.In addition, air-supply layer is hollow structure, circumferential side wall is equipped with filter 11, extraneous
Cold air enters air-supply layer after filter filters, and then rises and sequentially passes through packing layer and spraying layer.Layer lower part blow equipped with one
Inclined unhurried current plate 12, the 12 higher one end of unhurried current plate are connected with filter 11, and water tank 7, and its surface are stretched into lower one end
In wavy.
The top of tower body 1 is additionally provided with air duct 2, and the first wind turbine 8 is equipped in air duct.2 top of air duct is connected with U-shaped collecting tank 10,
Collecting tank is wide at the top and narrow at the bottom, and top is connected with a taper top 9, and 9 top of taper top is provided with gas outlet, and the second wind is equipped in gas outlet
Machine.Taper top 9 and U-shaped collecting tank 10 collectively form secondary collection device.
