Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
Fig. 1 is that the utility model has the high temperature closed cooling tower front of pre-cooler along main pipeline and coil pipe cross-sectional view; Fig. 2 is the high temperature closed cooling tower side structure schematic diagram that the utility model has pre-cooler.
Refer to Fig. 1 and Fig. 2, the high temperature closed cooling tower of what the utility model provided have pre-cooler, comprise cooling column body 1, spray arm 7 is provided with in described cooling column body 1, described spray arm 7 is connected with feeding spraying pump 2 by the first main pipeline 3, first group of serpentine coil 11 and heat radiation filler screen pack 4 is provided with below described spray arm 7, wherein, the bottom of described cooling column body 1 is water tank 5, be provided with second group of serpentine coil 12 in described water tank 5, described second group of serpentine coil 12 is connected with first group of serpentine coil 11 by the second main pipeline 9.
The high temperature closed cooling tower of what the utility model provided have pre-cooler, wherein, the water inlet end of described second group of serpentine coil 12 is high temperature inlet 15, and water side is middle temperature liquid outlet 16; The water inlet end of described first group of serpentine coil 11 is middle temperature inlet 17, and water side is low temperature liquid outlet 18; The fluid temperature (F.T.) of described high temperature inlet 15 can up to 80 DEG C ~ 90 DEG C, the fluid temperature (F.T.) of described middle temperature liquid outlet 16 and middle temperature inlet 17 is about 60 DEG C, and the fluid temperature (F.T.) of described low temperature liquid outlet 18 can control to 35 DEG C and following.Described spray arm 7 is evenly distributed with multiple nozzle 8; The top of described cooling column body 1 is provided with blower fan 6 and forms damp-heat air outlet 20; Top and the side of described cooling column body 1 are provided with fresh inlet 19; Described cooling column body 1 is also provided with access door 10.
The high temperature closed cooling tower of what the utility model provided have pre-cooler, operation principle is as follows: by arranging first group of serpentine coil 11 and second group of serpentine coil 12, first consider to avoid overheated high-temperature water to make shower water at copper pipe surface flash evapn, therefore make two cover coil pipes as shown in the figure, the high temperature fluid entering cooling tower by before first group of serpentine coil 11 first through second group of serpentine coil 12.According to the operation principle of heat exchanger, because second group of serpentine coil 12 is immersed in water tank 5 completely, there is not water evaporation in the outer surface of its coil pipe, is fluid and water logging heat exchange completely, utilizes the circulation of shower water in cooling tower to be cooled and carry out heat exchange at closed conduit inner fluid.High temperature fluid enters first group of serpentine coil 11 by the second main pipeline 9 again after the precooling of second group of serpentine coil 12, thus solves the problem that airtight cooling tower high temperature fluid can not cool in the easy fouling of first group of serpentine coil 11 outer surface.
The utility model can realize in not too large space high temperature fluid fast cooling be because shower water be cooled after temperature and high temperature fluid Temperature Difference Ratio comparatively greatly, thus heat exchange is rapid.Be set as 60 DEG C by the fluid after lowering the temperature, shower water water leg is by reaching less than 35 DEG C after cooling.By calculating the hot property of different fluids, the heat exchange area of setting heat exchanger, reaches the effect of precooling.The high-energy hot water sucking-off that feeding spraying pump 2 will swap out, falls into water tank 5 as pre-cooled water source through heat radiation filler screen pack 4 after sprinkling, and drives air flowing that hot water is down to desirable temperature through blower fan 6.
Hot water after preliminary cooling enters first group, cooling tower top serpentine coil 11 through piping again, now shower water drops on first group of serpentine coil 11 surface, coil pipe major part area is wrapped, the heat of fluid passes to shower water by tube wall, now dry air is drawn in cooling tower by blower fan 6, when spraying water droplet and contacting with air, on the one hand owing to there is pressure differential between water vapour surface and air, produce Evaporation Phenomenon under the effect of the pressure, heat most in water is taken away i.e. evaporation heat transfer; On the other hand by the transmission of heat by contact of air and water, thus to the medium cooling in coil pipe.
The shower water absorbing heat is dropped in heat radiation filler screen pack 4, hot water forms moisture film when flowing through filling surface and air carries out heat exchange, in tower static pressure effect under, hydrone is constantly to air evaporation, become water vapour molecule, the mean kinetic energy of remaining hydrone just can reduce, thus the temperature of shower water is declined.
The high temperature closed cooling tower of what the utility model provided have pre-cooler, wherein, described first group of serpentine coil 11 comprises many serpentine coils, the water inlet end of described many serpentine coils is all connected by collecting pipe 14 with water side, be provided with dividing plate 13 in described collecting pipe 14, many serpentine coils are divided into some groups and are together in series by described dividing plate 13.Similarly, described second group of serpentine coil 12 also comprises many serpentine coils, the water inlet end of described many serpentine coils is all connected by collecting pipe 14 with water side, is provided with dividing plate 13 in described collecting pipe 14, and many serpentine coils are divided into some groups and are together in series by described dividing plate 13; Again that the serpentine coil group after series connection is in parallel by collecting pipe, thus tube pass length is set flexibly, be easy to installation and maintenance, meet various cooling requirement.
In sum, the utility model has filled up the space record that closed cooling tower cools at high-temperature water, can effectively cool the high-temperature water of more than 80 DEG C, lower the temperature, and is significantly promoted by the highest chilling temperature that closed cooling tower can cool.And solve the phenomenon that shower water evaporates because coil surface temperature is overheated simultaneously, ensure that the rate of water make-up of shower water is close with common closed cooling tower.Make that coil surface can not exist moisture evaporation and fast fouling cannot the situation of normal heat exchange.Relative in former closed cooling tower, increase only one group of serpentine coil and just reach the object cooled high-temperature water, the cost of increase is very low, and use procedure and operation maintenance are also about the same with former closed cooling tower, only need carry out insulation process at the pipeline of cooling tower outside, prevent from scalding; Just can realize the lifting of at least 20 DEG C of coolant water temperatures.
Although the utility model discloses as above with preferred embodiment; so itself and be not used to limit the utility model; any those skilled in the art; not departing from spirit and scope of the present utility model; when doing a little amendment and perfect, therefore protection domain of the present utility model is when being as the criterion of defining with claims.
