Abstract
The utility model relates to the technical field of a cooling tower, in particular to a hollow cooling tower without a filler part. The hollow cooling tower comprises a tower body, a fan, a reduction box, a spray nozzle and a water inlet pipe, wherein the fan is connected with the reduction box and is arranged on the upper part of the tower body; a water distribution system and a water collector are arranged in the tower body; the spray nozzle is arranged on the water distribution system which is communicated with the water inlet pipe; and the water collector is supported on the water distribution system. The hollow cooling tower causes the effluent direction of the spray nozzle with reverse effluent rotational flow direction to clash by two atomizing spray nozzles capable of inflowing along a tangent, the kinetic energy of a water drop is consumed, and the consumption of energy during collision further breaks the water drop, so the effluent grain diameter of the spray nozzle is small enough and uniform under low inflowing pressure. The utility model has good cooling effect and has small possibility of scaling and accumulating impurities.
Description
Technical field
The utility model relates to the technical field of cooling tower, especially a kind of hollow cooling tower that does not have the filler part.
Background technology
That generally uses at present has in the filling cooling tower, because the performance of filler own is limit, every kind of filler all has certain withstand temperature upper limit, when the processing water temperature is higher than this limit value, filler will flexural deformation, causes its performance sharply to descend, and can not satisfy designing requirement.When handling the recirculated water of high turbidity and easily fouling, the higher relatively film filling surface of cooling effectiveness is easy to adhere in the water impurity and fouling and builds up, cause the hydrophilic ability of filler to decline to a great extent, cooling effectiveness decreases, when gathering impurity and acquire a certain degree, filler itself can not bear this weight, filler fracture, collapse phenomenon occur.The hollow type cooling tower is owing to removed the filler part, thereby the decline and the destruction of the carrier performance of having avoided former thereby having caused owing to water quality, processing high temperature, high turbidity, easy fouling recirculated water are had great significance, use also more and more widely in the processing of middle temperature recirculated water.
The key that cooling tower carries out the recirculated water cooling is to make aqueous vapor carry out sufficient heat exchange, the different mechanisms of action (as drip, diaphragm type etc.) by filler in Packed cooling tower increase the surface area that following trickle drips greatly, thereby increased the area of water and air contact, make aqueous vapor carry out sufficient heat exchange, the temperature of recirculated water drops to designing requirement.In the hollow type cooling tower, owing to there is not filler, reach the purpose of heat exchange, just must make the drop particle diameter of trickle section enough little, thereby increase the contact area of water and air as far as possible, this just makes water distribution system become the key component of hollow cooling tower, adopts tangent line water inlet shower nozzle arranged in pairs to solve this problem, under this kind water distribution system situation, drop particle diameter is less than 1mm, water distribution is all right, and no hollow phenomenon can satisfy the requirement of normal aqueous vapor heat exchange fully.
In the hollow cooling tower because the atomizing of water droplet, the increase of water may cause wafing, therefore the quality of water collection device performance also becomes the key issue in the design of hollow cooling tower, adopt SJ type reinforcement arc water collection device, because its stable performance, the regimen condition of wafing of hollow cooling tower is controlled effectively, equipment is improved greatly to the influence of surrounding environment.The height of receiving water efficient in cooling tower equipment also directly has influence on the service life of fan blade.The fan blade long-term work is in the water vapor atmosphere of high humility, blade tip is with the linear velocity cutting damp-heat air of 60～70m/s, it is big more to the infringement of fan blade that water in air is dripped content big more (the receipts water efficient that is water collection device is low more), practical application shows: in the cooling tower equipment in order of magnitude of the every reduction of receipts water efficient of quantity of circulating water, then can improve 2～3 years (be about 10 years the normal service life of blade) service life of blade, obvious economic.
Thereby the hollow cooling tower removed the filler part make the resistance of whole tower descend significantly (actual measurement show the resistance of filler part account for the tower drag overall 2/3), the also corresponding decline of blower fan power consumption, though the spout of hollow cooling tower requires pressure to have the spout of filling cooling tower to require pressure high slightly, but comprehensively comparatively speaking, especially bigger to treatment scale tower, total power consumption of tower is more obvious than descending, remarkable in economical benefits.
The utility model content
The technical problems to be solved in the utility model is: a kind of filler part, less scaling hollow cooling tower of need not is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of hollow cooling tower, comprise tower body, blower fan, reduction box, shower nozzle and water inlet pipe, blower fan is connected with reduction box and is installed in the top of tower body, be provided with water distribution system and water collection device in the tower body, shower nozzle is arranged on the water distribution system, water distribution system is connected with water inlet pipe, and water collection device is supported on the water distribution system.
Water distribution system have the water inlet of paired layout and tangent line shower nozzle, connect the connector and the locking device of shower nozzle, shower nozzle arranges that in pairs water outlet forms spray, this arrangement form makes the water outlet water droplet enough little and water distribution is even, water distribution does not have the hollow phenomenon.
Shower nozzle has housing that adopts the ABS material and the deflection cone that is arranged on the housing inner chamber, make the movement locus of the current that enter shower nozzle more regular, flow direction is more reasonable, the flow velocity of current each point in the shower nozzle die cavity and dynamic pressure, static pressure variation have more designability, thereby reached under low intake pressure condition atomizing effect has preferably been arranged, be the purpose of less water outlet drop particle diameter, changing the shower nozzle service pressure is 5～6mH
2O.
In order to strengthen its stability, water collection device is shaped as SJ type reinforcement arc, and the drift ice situation of hollow cooling tower is controlled effectively, and equipment is improved greatly to the influence of surrounding environment.
Check tower body internal work situation for convenience, also be fixed with down the tower steel ladder on the sidewall of tower body.
The beneficial effects of the utility model are, hollow cooling tower of the present utility model, atomizer by two tangent line water inlets, the opposite shower nozzle water outlet of water outlet eddy flow direction is clashed, the kinetic energy of water droplet is consumed, and the consumption of energy makes water droplet further broken during collision, has realized at lower intake pressure lower nozzle water outlet particle diameter enough little and even like this, thereby reached good cooling results, less scaling and be difficult for gathering impurity.
