Abstract
The utility model provides a height adjustable target spray head, belonging to the field of cross-flow cooling tower circulating water. The height adjustable target spray head adopted by cross-flow cooling tower-pool type water distribution has a high requirement to the surface of the water distributing pool. Each part of the pool surface of the existing cement prefabricated plate water distributing pool differs a lot from other parts, leading to non-uniform water and air distribution of the cooling water, decline of the cooling efficiency, etc. The utility model has the advantages that the water level above the spray head under various levelness of the pool bottom is kept identical, the uniform water and air distribution for the tower is ensured, the cooling efficiency is enhanced, the force of the tower reaches 100%, and the service life of filling material is enhanced. The utility model is suitable to be applied to the cross-flow cooling towers of various pool type water distribution.
Description
The utility model belongs to crossflow cooling tower recirculated water field.
The fine or not key of crossflow cooling tower cooling effect is that recirculated cooling water will be sprayed on the interior filler of cooling tower equably, has only even water distribution, can accomplish that just air distribution is even, thereby guarantee the cooling effectiveness of tower.And even water distribution is that the water that is used for cooling water is sprayed onto on the filler chews or shower nozzle.The target formula shower nozzle of sluicing usefulness under the existing crossflow cooling tower distribution reservoir, see Fig. 1, it is to take over a business 5 target formula sprayer body 1 and place the adjustable ring that has of its inside to take over a business 7 Flow-rate adjustment ring 6 and constitute by having the floral disc 2 that dabbles, non-return fin 3, ribs 4 and sprayer body.Adjustable ring take over a business 7 and sprayer body take over a business between 5 two planes to be level and smooth tight fit, the Flow-rate adjustment effect of Flow-rate adjustment ring 6 mainly realizes by the size of Flow-rate adjustment ring 6 straight-tube shape section diameters, target formula shower nozzle by means of non-return fin 3 and sprayer body take over a business 5 with the cat head distribution reservoir on target formula shower nozzle closely fixing by the dress hole.This target formula shower nozzle, when being used for wooden cooling tower distribution reservoir abroad, since wooden distribution reservoir pond face machining accuracy height, the levelness height, and water distribution is even easily, so result of use is better.Yet, at present, numerous cooling tower distribution reservoir pond face cement pre-fabricated panel assembly unit, the pond face levelness of different parts differs bigger, generally at 50～80mm.Therefore cause the distribution reservoir pond face depth of water difference of different parts, the position that liquid level is low, water seal does not live shower nozzle, cause race wind, even water occurs and chew withered exposing, the high position of the liquid level then depth of water can reach 80mm, the shower nozzle at this position then discharge is excessive, water curtain is excessive in the tower, and this not only can smash filler, also causes cold wind can't pass, the water distribution inequality causes the air distribution inequality, operation can more worsen, and the cooling effectiveness of cooling tower is descended, and causes exerting oneself of tower can only reach 50～70%.For addressing this problem, there is the people once to attempt whole distribution reservoir is divided into several less distribution reservoirs with dividing plate, reducing the serious uneven problem of its trickle, but poor effect.
For thoroughly solving the problem that above-mentioned prior art exists, the utility model provides a kind of can both guarantee that the liquid level on the target formula shower nozzle is identical under the face levelness of various crossflow cooling tower distribution reservoirs pond, thereby can realize that cooling tower water distribution air distribution is even, stable operation makes cooling tower reach the target formula shower nozzle of EIAJ state---adjustable height target formula shower nozzle.
For reaching above-mentioned purpose, the technical scheme that the utility model adopted is, on the basis of former target formula nozzle structure, increased a device that is called flow regulator 8 again in the inside of its Flow-rate adjustment ring 6, flow regulator 8 is cylinder-like bodies that have pin thread, its top is the guide ring 9 of similar skylight structure, the end face of guide ring 9 can have opening, the side has grizzly bar shape opening to be referred to as guide ring inlet 10, flow regulator 8 and to have between the Flow-rate adjustment ring 6 of negative thread be that screw thread flexibly connects, flow regulator 8 exposures in sprayer body take over a business 5 or the adjustable ring height of taking over a business on 7 planes realize by screwing flow regulator 8, and take over a business on 7 to fix at adjustable ring by locking nut 11.This target formula shower nozzle is called adjustable height target formula shower nozzle.
In adjustable height target formula shower nozzle of the present utility model, no matter the levelness at each position of distribution reservoir is how, in use, as long as its guide ring porch is transferred to level, the above depth of water unanimity in guide ring porch just can guarantee all raisings of even cooling effect of full tower trickle everywhere like this.The vertical grizzly bar shape that similar skylight structure is made in the guide ring porch can also play impurity in the filtered water stream, prevent that it from entering the problem that results in blockage in Flow-rate adjustment ring device 8 or the target formula sprayer body 1.
In the utility model, adjustable thread depth on the flow regulator 8 depends on the maximum disparity of distribution reservoir pond face levelness, flow regulator 8 exposures in sprayer body take over a business 5 or the adjustable ring height of taking over a business 7 planar sections depend on the height of liquid level in the cooling tower distribution reservoir.If cooling tower distribution reservoir pond face is low, water level must be high relatively in this pond, position, trickle is even when wanting to reach the cooling tower operation, air distribution is even, turn-knob must make progress the flow regulator of the target formula shower nozzle on this position, its height that raises just can make the depth of water more than the target formula shower nozzle guide ring inlet at other position in the above depth of water of the guide ring inlet of this target formula shower nozzle and the distribution reservoir identical, and vice versa.
In addition, adjustable height target formula shower nozzle of the present utility model can adopt various corrosion-resistant, heatproofs, anti-aging, material manufacturing that certain toughness is arranged, is preferably and adopts nonmetallic materials engineering plastics or polypropylene manufacturing.
Compared with prior art, adjustable height target formula shower nozzle of the present utility model has the following advantages:
1. the levelness of cooling tower distribution reservoir pond face is not had specific (special) requirements,, can guarantee the cooling tower even water distribution no matter cooling tower distribution reservoir pond each position levelness of face has differed much.
2. because the cooling tower even water distribution, air distribution also easily evenly makes exerting oneself of tower bring up to 100% from 50～70%, has improved cooling effectiveness greatly.
3. can improve the service life of cooling tower filler greatly, because of even water distribution, the excessive problem that smashes filler of no water curtain takes place.
Adjustable height target formula shower nozzle of the present utility model is applicable to the various pond formula water distribution crossflow cooling towers application of circulation.
