Description
Technical field
The present invention relates to counterflow cooling tower, especially counterflow cooling tower water distribution liquid distribution, specifically a kind of water distribution uniformity device of realizing under the counterflow cooling tower unsteady flow.
Background technology
Counterflow cooling tower is heat abstractor indispensable in the central air conditioner system, and its effect is evenly to spread on the filler of below advancing tower hot water, by the contact area of increase with air, reaches reduction water temperature purpose with the cold air sufficient heat exchange.
Its water-distributing device generally has following three kinds, as shown in Figure 1, a kind of is at water inlet pipe 1 horizontal water-locator to be installed, generally formed by three pipe 4 roads, horizontal water-locator side has aperture 3, when water flow jet goes out, utilize acting in opposition to promote water-locator rotation while current and evenly trickle down on filler 2, to realize the water distribution uniformity of cooling tower filler.But counterflow cooling tower is owing to be to utilize the reaction force of current to promote the water-locator rotation, and water-locator will stop the rotation when little or hydraulic pressure was not enough when current, caused cooling tower filler to only have the part water distribution, and cooling effectiveness descends.Cause easily simultaneously obstruction owing to water distributing pore is less.Such structure also can cause the loss of waterpower lift.Simultaneously such structure is owing to there is moving component to be easy to damage, and can cause also that in addition large the and far away current of hole current close to the trunk line are little, and the water distribution non-uniform phenomenon when countercurrent tower occurs less than metered flow is serious, causes the decrease in efficiency of cooling tower.
In order to solve the shortcoming of turning spurt water device meeting loss waterpower lift, people also have the water-distributing device of another method of employing, as shown in Figure 2, by pipeline 6, at each arm water-distribution nozzle is installed, from the current of water-distribution nozzle ejection by baffle device for water 10,, 11 break up.Realizing water distribution uniformity, but it is many from the water close to the trunk line and shower nozzle away from the trunk line does not have the phenomenon of water current hour also can to occur.Water distribution non-uniform phenomenon in the time of can causing low discharge equally.
Other has the method for utilizing the rotation water distributing shower nozzle that adopts, namely utilize pressure to promote the shower nozzle fast rotational and realize water distribution uniformity, but discharge be hour except shower nozzle can't rotate, and current also can occurring, water close to the trunk line hour to occur many and shower nozzle away from the trunk line does not have the phenomenon of water.Water distribution non-uniform phenomenon in the time of can causing low discharge equally.Simultaneously such structure is because the shower nozzle fast rotational causes shower nozzle to be easy to damage.

Summary of the invention
The objective of the invention is for the problems referred to above, propose a kind of water distribution uniformity device under can the realization counterflow cooling tower unsteady flow of water distribution uniformity.
Technical scheme of the present invention is:
A kind of water distribution uniformity device of realizing under the counterflow cooling tower unsteady flow, it comprises water inlet pipe and horizontal water-locator, in the cooling tower body, horizontal water-locator is installed on the delivery port of water inlet pipe, it is characterized in that described horizontal water-locator comprises a plurality of water distributors and water-distribution nozzle, the water inlet of each water distributor is connected with water inlet pipe, and a plurality of water-distribution nozzles are installed in respectively on the body of corresponding water distributor, a plurality of water-distribution nozzles on each water distributor are communicated with, and each water-distribution nozzle all is higher than water distributor.
Be equipped with several apopores on the vertical side face of each water-distribution nozzle of the present invention, apopore is vertical slot and/or vertical alternate hole or groove.
Apopore of the present invention is circular or square.
The height of apopore of the present invention all is higher than corresponding water distributor.
The different water distributor of a plurality of height is installed on the water inlet pipe of the present invention.
Beneficial effect of the present invention:
When the present invention changes in discharge, also can realize the water distribution uniformity of cooling tower.Solve simultaneously the shower nozzle that occurs because of moving component or turning spurt water device and rotary nozzle and held flimsy disadvantage.
Water-distribution nozzle low price of the present invention has effectively been saved production cost.

The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 3, a kind of water distribution uniformity device of realizing under the counterflow cooling tower unsteady flow, it comprises water inlet pipe 1 and horizontal water-locator, water inlet pipe 1 is installed in the cooling tower body, horizontal water-locator is installed on the water inlet pipe 1, described horizontal water-locator comprises a plurality of water distributors 14 and water-distribution nozzle 12, the water inlet of each water distributor 14 is connected with water inlet pipe 1, a plurality of water-distribution nozzles 12 are installed in respectively on the body of corresponding water distributor 14, a plurality of water-distribution nozzles 12 on each water distributor 14 are communicated with, and each water-distribution nozzle 12 all is higher than water distributor 14.
Be equipped with several apopores 13 on the vertical side face of each water-distribution nozzle 12 of the present invention, apopore 13 is vertical slot and/or vertical alternate hole or groove.
Apopore 13 circles or square of the present invention.
The height of apopore 13 of the present invention all is higher than corresponding water distributor 14.
The different water distributor 14 of a plurality of height is installed on the water inlet pipe 1 of the present invention.
Its operation principle is: after the water inlet of cooling tower water inlet pipe, flow to each horizontal water-locator, according to the communicating pipe equilibrium principle, when the water-distribution nozzle water yield close to trunk line is many, must overcome terrestrial gravitation, at this moment water-distribution nozzle will produce counter-pressure, this counter-pressure is applied on the trunk line, pass to the water level water-distribution nozzle less than low wash water, because trunk line is each water-distribution nozzle of UNICOM, at this moment since the balance pipe principle will each water-distribution nozzle of balance water level, make each water-distribution nozzle at same water level water distribution.No matter how the trunk line flow changes, the water yield that flows to each water-distribution nozzle is much the same like this, and the water distribution when changing with the realization water yield is even.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
