[0002] Compressed air energy storage power station is a new type of energy storage mode, and its main system is a compression system and an expansion system, the compression system compresses normal air to air of a certain pressure through a compressor and stores it in a gas storage library, etc., to achieve the purpose of energy storage. The expansion system enters the turbine of the air of a certain pressure, and realizes the process of energy release through the work of the air. The air after work is discharged to the atmosphere, and the whole system is an open system.

[0003] In the construction process and the debugging stage of the compressed air energy storage power station, the blow pipe process occupies a very key position. The existing cooling method generally exists the difficulty that the cooling efficiency is difficult to reach the standard, and the heat cannot be discharged in time and effectively, so that the pipeline system is in high temperature working condition for a long time. This not only seriously threatens the durability of the pipeline material, but also may cause the pipeline deformation or even rupture due to local overheating, greatly weakening the safety and stability of the system operation. At the same time, a large amount of water resources are consumed in a extensive way, but the cooling effect optimization matching with it cannot be realized. The inefficient water use mode not only leads to the serious waste of water resources, but also increases the burden of the power station operation cost in the face of the increasing scarcity of water resources. Therefore, we provide a compressed air energy storage power station blow pipe closed water circulation cooling device to solve the above problems. Utility model content

[0022] Please see Figures 1-4In this utility model, a closed-loop water circulation cooling device for a compressed air energy storage power station includes a blower body 1. A base 2 is fixedly connected to the bottom surface of the blower body 1. An exhaust port 10 is fixedly connected to the upper surface of the blower body 1. A temperature sensor 15 is fixedly connected to the inner wall of the exhaust port 10. A cooling groove 18 is formed on the inner wall of the blower body 1. A set of cooling pipes 19 is fixedly connected to the inner wall of the cooling groove 18. A coolant storage tank 7 is fixedly connected to the right side of the blower body 1. A heat exchanger 8 is fixedly connected to the right side of the coolant storage tank 7. A mounting base 11 is fixedly connected to the back of the main body 1. A circulating pump 12 is fixedly connected to the back of the mounting base 11. A filter 13 is fixedly connected to the back of the heat exchanger 8. The filter 13 is connected to the circulating pump 12 through a conduit. An output pipe 14 is fixedly connected to the output end of the circulating pump 12. One end of the output pipe 14 away from the circulating pump 12 passes through the blowpipe body 1 and extends into the interior of the cooling tank 18. The other end of the output pipe 14 away from the circulating pump 12 is connected to a cooling pipe 19. The other end of the cooling pipe 19 passes through the blowpipe body 1 and extends into the blowpipe through a conduit. The other end of the cooling pipe 19 on the outside of the main body 1 is connected to the coolant storage tank 7 through a conduit. The bottom surface of the base 2 is fixedly connected to the controller 5. The temperature sensor 15 monitors the gas temperature at the exhaust port 10 in real time and transmits the data to the controller 5. The circulation pump 12 is started under the control of the controller 5 to draw out the coolant from the coolant storage tank 7 and deliver it to the cooling pipe 19 through the output pipe 14. The heat of the high-temperature gas is transferred to the coolant in the cooling pipe 19 through the pipe wall of the blowpipe body 1. After absorbing the heat, the temperature of the coolant rises. The coolant that has absorbed the heat flows out from the cooling pipe 19 and enters the heat exchanger 8 through the conduit. Heat exchange takes place in the heat exchanger 8. After being cooled by the heat exchanger 8, the coolant passes through the filter 13. The filter 13 removes impurities from the coolant. The filtered coolant is then drawn back by the circulation pump 12 to enter the next cooling cycle. This cycle continues, continuously removing the heat of the gas in the blowpipe body 1, thus cooling the blowpipe. This effectively prevents deformation and damage to the blowpipe and related equipment caused by high temperature, and greatly extends the service life of the equipment.

[0023] A touch panel 6 is fixedly connected to the front of the blowpipe body 1. The touch panel 6 makes it easy for staff to operate the equipment. Two mounting feet 3 are fixedly connected to the bottom surface of the base 2. Two positioning holes 4 are opened on the upper surface of each mounting foot 3. The mounting feet 3 make it easy for staff to connect this device to external equipment. A parameter label 9 is provided on the right side of the heat exchanger 8. The left side of the parameter label 9 is fixedly connected to the right side of the heat exchanger 8. The parameter label 9 improves the identification of the equipment.

[0024] Two support blocks 20 are fixedly connected to the bottom surface of the heat exchanger 8. The left side of each support block 20 is fixedly connected to the right side of the blowpipe body 1. The support blocks 20 can fix and support the heat exchanger 8. The inside of the blowpipe body 1 is provided with an installation groove 16. The inner wall of the installation groove 16 is fixedly connected with an insulation layer 17. The insulation layer 17 can reduce heat loss and improve cooling efficiency.

[0025] The working principle of this utility model is as follows:

[0026] In use, first connect the blowpipe body 1 to the external equipment through the mounting feet 3 and positioning holes 4. During operation, as the blowpipe moves, the temperature sensor 15 monitors the gas temperature at the exhaust port 10 in real time and transmits the data to the controller 5. The circulation pump 12 starts under the control of the controller 5, drawing out the coolant from the coolant storage tank 7 and delivering it to the cooling pipe 19 through the output pipe 14. The heat of the high-temperature gas is transferred to the coolant in the cooling pipe 19 through the pipe wall of the blowpipe body 1. After absorbing the heat, the coolant temperature rises. The coolant that has absorbed the heat flows out from the cooling pipe 19 and enters the heat exchanger 8 through the conduit. Heat exchange takes place in the heat exchanger 8. After being cooled by the heat exchanger 8, the coolant passes through the filter 13. The filter 13 removes impurities from the coolant. The filtered coolant is then drawn back by the circulation pump 12 to enter the next cooling cycle. This cycle continues, continuously removing the heat of the gas in the blowpipe body 1, thus cooling the blowpipe.
