The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
Combined type high temperature cold water unit of the present invention is composited by water jet aerial cooler and reverse-flow no-padding and spraying cooling tower.Fig. 1 is arranged in the embodiment in the same cabinet with water jet aerial cooler and reverse-flow no-padding and spraying cooling tower, has showed the relative position of water jet aerial cooler and reverse-flow no-padding and spraying cooling tower.
Water jet aerial cooler 20 is made up of high temperature cold water aerial cooler 14 and recirculated water spray equipment 22; Recirculated water spray equipment 22 comprises the nozzle 2 and water tank a13 that is arranged at high temperature cold water aerial cooler 14 above and belows respectively; Pipeline is set in the water tank a13 is connected with nozzle 2 through water pump a12, the top of high temperature cold water aerial cooler 14 is provided with air inlet a1.
In the reverse-flow no-padding and spraying cooling tower 21, comprise blower fan 4, the water collection device 5 that drives by motor 3, the diaphragm 9 that is arranged side by side the swirling flow atomizer 6 on water inlet pipe 7 and air intake is moved upward from top to bottom; Between swirling flow atomizer 6 and the diaphragm 9 secondary-atomizing device 8 is set; Bottom in the reverse-flow no-padding and spraying cooling tower 21 is provided with water tank b10; The sidewall of the reverse-flow no-padding and spraying cooling tower 21 between water tank b10 and the diaphragm 9 is provided with air inlet 11, and the position that is provided with of reverse-flow no-padding and spraying cooling tower 21 makes its air intake come from the air draft of water jet aerial cooler 20.
Water tank b10 is connected with water collector 17 through pipeline; Valve a15 and water pump b16 are set on the pipeline; Water collector 17 is connected with user side through pipeline, and user side also is connected with water knockout drum 19 through pipeline, is used for the backwater input water knockout drum 19 with user side; Water knockout drum 19 is connected with water inlet pipe 7 through one road pipeline; Water knockout drum 19 also is connected with the water inlet pipe of high temperature cold water aerial cooler 14 through another road pipeline, is respectively arranged with valve b18 on the two-way pipeline that water knockout drum 19 is told, and the outlet conduit of high temperature cold water aerial cooler 14 is connected with water inlet pipe 7.
Combined type high temperature cold water unit of the present invention; Make high temperature cold water aerial cooler top spray recirculated water; The precooling treatment that the outdoor air that is inhaled into is carried out no longer is simple sensible heat exchange process; But promptly have the sensible heat exchange that the processing procedure of latent heat exchange is arranged again in the recirculated water of outdoor air, spray and the pipe between the high temperature cold water three, compare with the heat exchanger effectiveness that does not have the dry-type air cooler of water spray and greatly improve.Reverse-flow in addition cooling tower without filling material has been removed the filler part of cooling tower, on the one hand, has avoided in the circulation that filler is prone to stop up, aging, distortion, embrittlement, scaling and grow defective such as bacterium; On the other hand, make whole tower almost become one " void tower ", greatly reduced SR in the tower, increased the cold air amount, the also corresponding increase of gas-water ratio.Also have reverse-flow no-padding and spraying cooling tower to arrange the secondary-atomizing device in addition, make water droplets littler, thereby increased the gas-liquid contacted specific surface area, improved the heat exchange efficiency and the heat of water and cold air.
The course of work of combined high temperature handpiece Water Chilling Units of the present invention:
1, during summer operation outdoor air in the flow process of this unit:
Outdoor air passes through air inlet a1, nozzle 2, high temperature cold water aerial cooler 14, air inlet b11, diaphragm 9, secondary-atomizing device 8, swirling flow atomizer 6, water inlet pipe 7, water collection device 5 successively, finally discharges via blower fan 4.During outdoor air process high temperature cold water aerial cooler 14; Promptly there is the sensible heat exchange that the process of latent heat exchange is arranged again between the high temperature cold water three in the recirculated water of outdoor air, spray and high temperature cold water aerial cooler 14 pipes; On the one hand the heat-exchange capacity of aerial cooler is increased greatly; Make outdoor air obtain effective precooling, cleaned aerial cooler on the other hand again and purified outdoor air; Outdoor air after process precooling and the purified treatment gets in the reverse-flow no filler spray tower 21 again and carries out the higher hot wet process of efficient with water droplets, thereby makes the cold water of supplying with user side, and water quality has also obtained guarantee.
2, the flow process of water system during summer operation:
The high temperature cold water that combined type high temperature cold water unit is produced is led to water collector 17 by water tank b10; Be transported to user side by water collector 17 through pipeline; Get back to water knockout drum 19 by user side then, backwater is transported to high temperature cold water aerial cooler 14 is transported to reverse-flow no-padding and spraying cooling tower 21 then jointly through pipeline with another backwater water inlet pipe 7 continuation sprays by water knockout drum 19 parts through pipeline.Backwater is to get into swirling flow atomizer 6 via water inlet pipe 7 tentatively to atomize in reverse-flow no-padding and spraying cooling tower 21 flow processs; The water droplet of preliminary atomizing further atomizes through secondary-atomizing device 8 and makes water droplets littler; Thereby increased the specific area of gas-liquid contact; Improve the heat exchange efficiency of water and cold air, then with precooling, purified treatment after outdoor air carry out hot wet process and get back to water tank b10 at last.
