The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment 1: as Fig. 2, shown in; The special-purpose closed cooling tower of a kind of middle frequency furnace; Comprise cyclic water tank 15, closed cooling tower body 1 and be used to control the Main Control Tank that closed cooling tower turns round, the middle part of closed cooling tower body 1 is equipped with the coil radiator of being made by copper pipe 2.Coil radiator 2 has water inlet 21 and water return outlet 22, has 10 degree angles between two horizontal straight tubes 23 that link to each other in the coil radiator 2.The water return outlet 22 of coil radiator 2 directly links to each other with the intermediate frequency power supply 17 on closed cooling tower body 1 next door and the distributive pipe 182 of body of heater 18.The water inlet 21 of coil radiator 2 links to each other with the bottom of cyclic water tank 15 through circulating pump 3.The top of cyclic water tank 15 links to each other with the return pipe 181 of intermediate frequency power supply 17 and body of heater 18 respectively, constitutes the closed circuit of a working fluid.Spray equipment and air cooling recirculation system are installed in closed cooling tower body 1; Water return outlet 22 places at coil radiator 2 are equipped with temperature sensor 4; Temperature sensor 4 links to each other with Main Control Tank, through Main Control Tank control spray equipment and air cooling recirculation system coil radiator 2 is cooled off.
Spray equipment comprises tank 5, water pump 6 and the shower 7 that is positioned at closed cooling tower body 1 bottom.Tank 5 links to each other with an end of water pump 6, and the other end of water pump 6 links to each other with shower 7.Shower 7 is positioned at the top of coil radiator 2, and shower 7 equal intervals are arranged with three shower nozzles 8.Tank ball-float valve 11 is installed in tank 5, is guaranteed to have sufficient cooling water in the tank 5.Dehydrater 12 is installed above shower 7, the tank 5 of dehydrater 12, shower nozzle 8 equal corresponding closed cooling tower bodies 1 bottom, and constitute a closed circuit with water pump 6.Water pump 6 links to each other with Main Control Tank, through the running of Main Control Tank control water pump 6.
The air cooling recirculation system comprises the louver(-vre) 9 and two blower fans 10 that are positioned at closed cooling tower body 1 top between tank 5 and coil radiator 2, and blower fan 10 links to each other with Main Control Tank.
Two temperature threshold value are set on Main Control Tank, are respectively first temperature value and second temperature value, spray equipment and air cooling recirculation system are controlled through first temperature value and second temperature value.Working fluid branches in intermediate frequency power supply 17 and the body of heater 18 through water return outlet 22 through in the coil radiator 2 in the circulating pump 3 suction closed cooling tower bodies 1 again, and working fluid is again by flowing back to cyclic water tank 15 in intermediate frequency power supply 17 and the body of heater 18.When working fluid flowed out from the water return outlet of coil radiator 2 22, the temperature sensor 4 that is positioned at water return outlet 22 places monitored the temperature of the working fluid here of flowing through, and signal is passed to Main Control Tank.
When the temperature that monitors the working fluid here of flowing through when temperature sensor 4 was lower than first temperature value, Main Control Tank control spray equipment and air cooling recirculation system were not all worked.
The temperature that monitors the working fluid here of flowing through when temperature sensor 4 is between first temperature value and second temperature value time, blower fan 10 runnings of a Main Control Tank control air cooling recirculation system.At this moment, closed cooling tower body 1 outer cold air gets in the closed cooling tower body 1 through louver(-vre) 9, and cold air is discharged to outside the closed cooling tower body 1 through blower fan 10, and takes away the heat that coil radiator 2 is distributed, and constitutes the air cool cycles.
When the temperature that monitors the working fluid here of flowing through when temperature sensor 4 was higher than second temperature value, the blower fan 10 of Main Control Tank control air cooling recirculation system and the water pump 6 of spray equipment were worked simultaneously.Water pump 6 is pumped into the water of the cooling usefulness in the tank 5 in the shower 7, and the water that will cool off usefulness through three shower nozzles 8 on the shower 7 again is sprayed on the coil radiator 2 of shower 7 belows coil radiator 2 is cooled off.In this course, a water part that is sprayed at the cooling usefulness on the coil radiator 2 splashes in the tank 5 and recycles, and another part becomes steam, and steam cools off liquefy water again and splashes in the tank 5 through the effect of dehydrater 12.
Linking to each other of coil radiator 2 has the angle of 10 degree between two horizontal straight tubes 23; When closed cooling tower need not use; Working fluid in the coil radiator 2 can flow back in the cyclic water tank 15 smoothly; When temperature is low, can avoid still having in the coil radiator 2 working fluid that does not reflux to cause coil radiator 2 explosions.Adopt closed cooling tower that working fluid is cooled off, need not to set up circulatory pool, reduce floor space, save maintenance cost; And can make whole cooling procedure intelligence and energy-conservation more.
Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
