The packless natural ventilation cooling tower is simple in structure, convenient to install, repair and maintain and stable to run, the construction and running cost can be reduced by 20 percent compared with that of a conventional natural ventilation cooling tower, and the packless natural ventilation cooling tower can be widely popularized to use in the water cooling field.
Description
Technical field
The utility model relates to the but cooling tower equipment in the field of water-cooled, particularly a kind of cooling stack.
Background technology
The circulation in thermal power plant adopts the secondary circulation cooling system of band cooling stack more, and the core structures of native system are cooling stack.Cooling stack is main with filling cooling tower mainly, the cooling principle of such cooling tower be make the water that flows down from top to down with from down and on air the process that fully contacts, carry out exchange heat, thereby reach cooling purpose.Cooling stack is made up of tower body, filler, central vertical shaft, water distribution system, water collection device, collecting-tank etc., and wherein filler is to accomplish the most important parts of cooling task, and the temperature drop that filler produced reaches about 65% of whole tower temperature drop.The material of filler is varied, and wooden filler, asbestos cement filler, plastic filler are arranged, no matter but be that which kind of filler all can produce certain resistance to the air-flow in the tower, cold air can't be contacted with water fully.
Therefore packless cooling tower just uses and gives birth to, and cooling tower without filling material in the market is mechanical-draft cooling tower, and the running of tower inner blower has increased power consumption greatly, though construction cost is lower than cooling stack, but operating cost is high.And the cooling stack that generally adopts in the industry at present is the cooling stack of band filler; The packing layer flowing resistance is big; And the surface area of filler is limited; Heat recirculated water and cold air contact area receive the long-pending restriction of filling surface, make and can not fully carry out heat exchange between heat recirculated water and the cold air.
The utility model content
The utility model technical issues that need to address provide a kind of simple in structure, economical and practical, install and safeguard all convenient, and high, the stable cooling stack of cooling effectiveness.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is following.
No filler cooling stack comprises tower body and is arranged on the atomizer on the distributing pipe line of tower body bottom that said distributing pipe line becomes concentric annular to be arranged on the tower body bottom, and the even cloth of atomizer is on the annular water distribution pipeline; The top of said annular water distribution pipeline is provided with the water collection device that supports through central vertical shaft in tower body and the tower body.
The improvement of the utility model is: said water collection device is positioned at the top of tower body, and the delivery port of water collection device is communicated with central vertical shaft; Be provided with the hydraulic turbine that utilizes high-order water gravitional force to generate electricity in the said central vertical shaft.
Because the technological progress of having adopted technique scheme, the utility model to obtain is following.
The utility model adopts atomizer to replace filler, and is with the high-order setting of water collection device, simple in structure; Installation and maintenance are easy to maintenance; Stable, more conventional cooling stack construction and operating cost can reduce about 20%, can be in but wide popularization and application in the field of water-cooled.Water collection device is arranged on the tower body top, can high-orderly collect fine droplet, and utilize the gravitional force of high-order water to generate electricity through the hydraulic turbine that is arranged in the central vertical shaft, has improved the utilization rate of the utility model cooling water.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of the utility model.
Wherein, 1. tower body, 2. atomizer, 3. water collection device, 4. annular water distribution pipeline, 5. central vertical shaft.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is explained further details.
A kind of no filler cooling stack, as shown in Figure 1, specifically comprise tower body 1, annular water distribution pipeline 4, atomizer 2, central vertical shaft 5 and water collection device 3.Said annular water distribution pipeline is concentric with tower body, is arranged on the bottom of tower body, for atomizer provides heat recirculated water to be cooled.The even cloth of atomizer supports with reinforced concrete column above herringbone column in cooling tower works on the annular water distribution pipeline, is used for the ducted heat recirculated water atomizing of annular water distribution, and sprays to tower body top.Water collection device is positioned at the top of annular water distribution pipeline and atomizer, the top of tower body, supports through the central vertical shaft in tower body and the tower body, and the delivery port of water collection device is communicated with central vertical shaft, is used to collect the droplet that has been cooled.
The utility model is in running; The ducted heat recirculated water of annular water distribution leans on the draft of cooling tower to move upward be atomized into tens microns fine droplet through atomizer after, and hot mist fully contacts with cold air in motion process; And move upward, guaranteed sufficient time of contact. alwaysThe injection direction of water smoke is consistent with the flow direction of cold air, promptly upwards sprays.In the process that moves upward; Because the coalescence and the cooling of water smoke; Heavier droplet is to the whereabouts, and lighter droplet then can upwards waft, and lighter droplet arrives the water collection device place and is collected in the central vertical shaft of back inflow; Discharge gravitional force through the hydraulic turbine in the central vertical shaft then and drive hydraulic turbine generating, be back at last in the cooling tower collecting-tank.In heat exchanging process, fine droplet has the rising and two processes that descend simultaneously, and cooling procedure has also comprised following current cooling and two processes of adverse current cooling.
The utility model is owing to cancelled filler, and the resistance of air-flow reduces greatly, and air capacity increases in the tower, because the droplet and the air contact area of atomizing have reached maximum, the more conventional cooling stack of cooling effect improves greatly simultaneously.Top at cooling tower is provided with water collection device, can prevent effectively that because the water loss that causes of wind, the high-order simultaneously droplet of collecting utilizes the gravitional force of water to generate electricity, and improves the utilization rate of the utility model cooling water.
