Abstract
The invention discloses an aqueous dispersion filler-free cooling tower, comprising a tower body. A water receiver, a nozzle and a water distribution pipe are arranged inside the tower body; the water receiver is located at the shoulder of the top end of the tower body; the water distribution pipe is arranged at a 1/3 position in the tower body from the bottom; the nozzle is arranged at the upper end of the water distribution pipe; and a water collecting plate is arranged at the bottom of the tower body. When the cooling tower provided by the invention does cooling operation, a water supply pipe is mounted at the lower part of an air cylinder in the tower body, so that hot water tangentially enters through the bottom of the nozzle, is jetted in a fog state from the upper part of the nozzle after high-speed rotation, and falls down at a position which is close to the water receiver. The water is in sufficient contact with air in an entire process, so that the cooling effect is obviously improved. Furthermore, compared with the prior art, a filling layer is eliminated for the aqueous dispersion filler-free cooling tower provided by the invention, so that water and air do not carry out heat exchange in the filling layer. Therefore, poor cooling efficiency caused by scaling and blocking of the filling layer can be solved; the cost caused by replacing the filling layer is greatly saved; and the labor resource cost is further saved simultaneously.
Description
Technical field
The present invention relates to cooling tower equipment, particularly relate to a kind of aqueous dispersion cooling tower without filling material, mainly be applicable to chemical field.
Background technology
At present, in China nitrogen fertilizer production enterprise, extensively adopt the force ventilation filling cooling tower, as shown in Figure 1; Be the structure of prior art force ventilation filling cooling tower, this cooling tower tower body (10) comprises water collection device (20), shower nozzle (30); Packing layer (40) and water-collecting tray (50), said water collection device (20) is located in the cooling tower tower body (10), and is positioned at tower body (10) upper end shoulder; Said shower nozzle (30) is located in the tower body (10); Be positioned at water collection device (20) lower end, said packing layer (40) is located at shower nozzle (30) lower end, and said water-collecting tray (50) is located at tower body (10) bottom.When using this cooling tower (10) to carry out cooling operations, circulating hot water is by the shower nozzle (30) of water collection device (20) bottom spray downwards, and (40) contact with upstream cold air and reach the purpose of cooling in packing layer.Its cooling is by way of mainly containing two: the one, and the transmission of heat by contact process, through the direct contact of water and air, high-temperature water is with the air of heat transferred low temperature; The 2nd, the evaporation heat transfer process, part water is taken away a large amount of gasification latent heats owing to being evaporated, simultaneously also with other water-cooled but, reach cooling effect.
But, in the existing this filling cooling tower (10), owing to be provided with packing layer (40); And this packing layer (40) tends to produce the flowing resistance height, and the air duct height is corresponding to be increased, and makes the also corresponding raising of structures cost; And because the filler aperture little, in the water impurity fouling serious, make packing layer (40) easy blocking; Make maintenance workload increase, and this structure also can directly cause cooling effect unstable.
So, need a kind of new cooling tower to address the above problem.
Summary of the invention
The objective of the invention is the deficiency to prior art, provide that a kind of cooling performance is stable, the aqueous dispersion cooling tower without filling material of good energy-conserving effect.
For realizing the foregoing invention purpose, a kind of aqueous dispersion cooling tower without filling material of the present invention can adopt following technical scheme:
A kind of aqueous dispersion cooling tower without filling material comprises tower body, and said tower body inside is provided with water collection device, shower nozzle, water distributor; Said water collection device is positioned at tower body top shoulder; Water distributor is located in the tower body 1/3 place apart from the bottom, and shower nozzle is located at the water distributor upper end, and said tower body bottom is provided with water-collecting tray.
Be preferably said water-collecting tray bottom and be provided with overflow pipe.
Further cooling tower is provided with filter before said shower nozzle.
The present invention compares prior art; Cancelled traditional packing layer, made that water is gentle not to carry out heat exchange in packing layer, it is poor to have solved the cold efficiency that causes because of the fouling of packing layer, obstruction; Also save the cost of changing packing layer greatly, also practiced thrift cost of human resources simultaneously.Shower nozzle of the present invention is connected the water distributor upper end, and water and cold wind is up spray simultaneously, and water is fully contacted with cold air, has greatly improved the cooling effectiveness of cooling tower.
The present invention has changed the water (flow) direction of cooling tower in the past, and water is fully contacted with cold air, has reached better cooling effect, and than existing cooling tower technology, has cancelled original packing layer, has practiced thrift cost greatly.
Description of drawings
Fig. 1 is the structural representation of prior art cooling tower.
Fig. 2 is the structural representation of a kind of aqueous dispersion cooling tower without filling material of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
As shown in Figure 2; A kind of aqueous dispersion cooling tower without filling material of the present invention comprises tower body 1, and said tower body 1 inside is provided with water collection device 2, shower nozzle 3, water distributor 4; Said water collection device 2 is positioned at tower body 1 top shoulder; Water distributor 4 is located in the tower body 1 1/3 place apart from the bottom, and shower nozzle 3 is located at water distributor 4 upper ends, and said tower body bottom is provided with water-collecting tray 5.
Be preferably said water-collecting tray bottom and be provided with overflow pipe 6.
Further cooling tower is provided with filter 7 before said shower nozzle.
When cooling tower carries out cooling operations; Because filling pipe 4 is installed on air duct bottom in the tower body 1; Hot water gets into through tangential, shower nozzle 3 bottom, and the rotation back is vaporific ejection by shower nozzle 3 tops at a high speed, falls after rise near water collection device 2 places; In the whole process time of contact of water and air longer, cooling effect obviously increases.
In cooling procedure, because along with last water is invented reducing of aperture, leaving water temperature but raises gradually; Reason be spray water highly gradually descend, water due to atomization decreases; For addressing this problem, preferably on water-collecting tray 5, increase an overflow pipe 6, when the circulation water consumption reduces; Unnecessary cold water will flow back to the pond from overflow pipe 6, thereby has further strengthened the cooling-down effect to recirculated water.
Because circulating water quality is relatively poor; Graininess magazine content is high in the water, causes the blockage problem of shower nozzle 3 easily, for addressing this problem; Filter 7 preferably is installed before shower nozzle 3; When solving shower nozzle 3 blockage problem, also purify water quality, helped preventing the blockage problem of other pipelines of cooling tower etc.
