Description

Technical Field

[0001] This application relates to the field of cooling equipment technology, and in particular to a power circulation device for a cooling system. Background Technology

[0002] Reactive power compensation devices are increasingly widely used, and synchronous condensers are one type of reactive power compensation device. A synchronous condenser is a synchronous motor that provides or absorbs reactive power to the power system. However, reactive power compensation devices generate a large amount of heat during operation, especially under high load conditions, where the heat dissipation is even more significant. This excessive heat can not only seriously affect the service life of the device but may even directly cause damage. Therefore, to ensure the normal operation of reactive power compensation devices and extend their service life, the cooling function of the power circulation device in the cooling system is particularly important. During the cooling process of the reactive power compensation device, the vibration of the main pump and the high-speed scouring flow of the cooling medium in the pipeline can cause rigid particles in the pipeline to detach and form impurities. When the cooling medium flows directly to the main pump after cooling, these impurities may damage the main pump, adversely affecting the normal operation of the power circulation device in the cooling system.

[0037] The following reference Figures 1 to 2 This application describes a cooling system power circulation device in an embodiment.

[0038] according to Figure 1 and Figure 2As shown, an embodiment of the cooling system power circulation device of this application includes a main pump module 10, a cooling device connection module 20, and a cooled device connection module 30. The main pump module 10 provides power for the flow of cooling medium in the pipeline. The cooling device connection module 20 connects the cooling system power circulation device to the cooling device, and the cooled device connection module 30 connects the cooling system power circulation device to the cooled device. The main pump module 10, the cooling device connection module 20, and the cooled device connection module 30 are connected sequentially to form the main circulation loop. The cooling system power circulation device adopts a modular design. The modular cooling device connection module 20 and the cooled device connection module 30 are connected to the main pump inlet pipeline 12 and the main pump outlet pipeline 13. The cooling system power circulation device is connected to the cooling device through the modular cooling device connection module 20, and to the cooled device through the modular cooled device connection module 30. This modular design facilitates easier and faster connection of the cooling system power circulation device to different cooling devices and cooled devices. In addition, the cooling system power circulation device can add new functional modules to the main pump inlet pipe 12 and the main pump outlet pipe 13 as needed, and can also add new functional modules between the main pump module 10, the cooling device connection module 20 and the cooled device connection module 30 to achieve standardization and universality of the device, while also facilitating maintenance and upgrades.

[0039] The main pump module 10 includes a main pump 11, a main pump inlet pipe 12, and a main pump outlet pipe 13; the cooling device connection module 20 includes a cooling device inlet pipe 21 and a cooling device outlet pipe 22, one end of the cooling device inlet pipe 21 is connected to the main pump outlet pipe 13, the other end of the cooling device inlet pipe 21 is connected to the inlet of the cooling device, and one end of the cooling device outlet pipe 22 is connected to the outlet of the cooling device; the cooled device connection module 30 includes a cooled device liquid supply pipe 31 and a cooled device liquid return pipe 32, one end of the cooled device liquid supply pipe 31 is connected to the other end of the cooling device outlet pipe 22, the other end of the cooled device liquid supply pipe 31 is connected to the inlet of the cooled device, one end of the cooled device liquid return pipe 32 is connected to the outlet of the cooled device, and the other end of the cooled device liquid return pipe 32 is connected to the main pump outlet pipe 13. The main pump 11 provides power for the flow of cooling medium in the main circulation pipeline. The return pipeline 32 of the cooled device is equipped with a first filter 15 to prevent impurities from entering the main pump 11. Both the main pump inlet pipeline 12 and the main pump outlet pipeline 13 are equipped with corrugated compensators 14 for vibration damping. When the cooling system power circulation device starts, the corrugated compensators 14 reduce the impact of the main pump 11 vibration on the cooling system power circulation device. Vibration damping reduces impurities formed by the shedding of rigid particles in the pipeline. The first filter 15 further filters impurities in the cooling medium, effectively preventing impurities from entering the main pump 11 and avoiding damage to the main pump 11 due to impurities. This improves the operational stability and reliability of the cooling system power circulation device.

[0040] The main pump outlet pipe 13, cooling device inlet pipe 21, cooling device outlet pipe 22, cooled device supply pipe 31, cooled device return pipe 32, main pump inlet pipe 12, and main pump outlet pipe 13 are connected in sequence to form the main circulation pipeline. The main pump 11 provides power for the flow of cooling medium in the main circulation pipeline. When the main pump 11 starts, the cooling medium flows in from the main pump inlet pipe 12, is pressurized by the main pump 11, and flows to the inlet of the cooling device through the main pump outlet pipe 13 and the cooling device inlet pipe 21. In the cooling device, after the cooling medium is cooled, it flows out from the outlet of the cooling device and into the cooling device outlet pipe 22. One end of the cooled device supply pipe 31 is connected to the cooling device outlet pipe 22, and the other end is connected to the inlet of the cooled device. The cooling medium flows out from the cooling device outlet pipe 22 and into the cooled device supply pipe 31, and then flows to the inlet of the cooled device through the cooled device supply pipe 31. When the cooling medium flows through the device being cooled, it cools the device and then flows out from the outlet of the device being cooled. The cooling medium flows into the return liquid line 32 of the device being cooled, where the first filter 15 filters the cooling medium to prevent impurities from entering the main pump 11. The main pump inlet line 12 is connected to the return liquid line 32 of the device being cooled. The filtered cooling medium flows out from the return liquid line 32 of the device being cooled and re-enters the main pump 11 through the main pump inlet line 12, forming a closed cooling system power cycle. The modular cooling device connection module 20 and the device being cooled connection module 30 are installed on the main pump inlet line 12 and the main pump outlet line (not shown in the figure). The cooling system power cycle device is connected to the cooling device through the cooling device connection module 20 and to the device being cooled through the device being cooled connection module 30. The modular design allows the cooling system power circulation device to be connected to the cooling device and the device being cooled more easily and quickly, which not only shortens the installation time, but also enhances the system's adaptability and flexibility, ensuring that the cooling system power circulation device can be put into operation more efficiently and reliably.

[0041] In some embodiments, the device to be cooled can be a synchronous condenser. During operation, the synchronous condenser generates a significant amount of heat, and its cooling significantly impacts the device's performance and reliability. Therefore, an effective heat dissipation method is essential. The cooling system power circulation device of this application provides excellent heat dissipation conditions for the synchronous condenser's operation. It not only effectively solves the heating problem of the synchronous condenser through temperature reduction but also reduces its energy consumption, providing a reliable guarantee for the safe and stable operation of the synchronous condenser.

[0042] In some embodiments, the first filter 15 is configured as a Y-type filter. The filter element of the Y-type filter is installed in a filter chamber that is easy to disassemble. Operators can easily clean the impurities in the filter element by simply opening the drain bolt or end cap at the bottom, without disassembling the entire device, greatly improving the convenience of maintenance. Due to its ease of cleaning and the fact that it does not require frequent filter element replacement, the Y-type filter has relatively low operating and maintenance costs, reducing operating and maintenance expenses and making it suitable for long-term use. The Y-type filter configuration also optimizes the flow path of the cooling medium, reducing the resistance of the cooling medium as it passes through the filter, thereby reducing pressure loss, improving efficiency, and ensuring the stability and reliability of the cooling system's power circulation device.

[0043] In some embodiments, the filter cartridge accuracy of the first filter 15 is set to 400 μm.

[0044] In some embodiments, the diameters of the main pump inlet pipe 12 and the main pump outlet pipe 13 are DN150.

[0045] In some embodiments, the diameter of the cooling device inlet pipe 21 and the cooling device outlet pipe 22 is DN150.

[0046] In some embodiments, the diameter of the cooling device supply line 31 and the cooling device return line 32 is DN150.

[0047] In some embodiments, both the main pump inlet pipe 12 and the main pump outlet pipe 13 are equipped with valves, which are butterfly valves, so that the main pump 11 can be repaired without stopping the system.

[0048] In some embodiments, the cooling device inlet pipe 21, the cooling device outlet pipe 22, the cooled device liquid supply pipe 31, and the cooled device liquid return pipe 32 are all equipped with valves, which are butterfly valves.

[0049] In some embodiments, the cooling system power circulation device further includes a base support module, which includes a base, main pump inlet and outlet supports, and pipe supports. All supports are bolted to the base. The main pump module 10 is bolted to the base. The cooling device inlet pipe 21 is mounted on the main pump inlet and outlet supports via pipe clamps and pipe seats. The cooling device outlet pipe 22 and the cooled device liquid supply pipe 31 are mounted on the pipe supports via pipe clamps and pipe seats. A first filter 15 is mounted on the cooled device return liquid pipe 32 near the periphery of the base for easy maintenance by operators.

[0050] according to Figure 1 and Figure 2As shown, in one embodiment of this application, the cooling system power circulation device further includes a buffer and pressure stabilizing module 40. The buffer and pressure stabilizing module 40 includes a buffer tank 41, a nitrogen cylinder 42, and a nitrogen pipeline 43. One end of the nitrogen pipeline 43 is connected to the buffer tank 41, and the other end of the nitrogen pipeline 43 is connected to the nitrogen cylinder 42. The buffer tank 41 and the nitrogen cylinder 42 are connected through the nitrogen pipeline 43. The buffer tank 41 is connected to the main pump inlet pipeline 12. The buffer and pressure stabilizing module 40 is used to provide pressure stabilization and buffering and to ensure that the main circulation pipeline is filled with cooling medium.

[0051] The top of the buffer tank 41 is filled with high-purity nitrogen gas at a stable pressure. The buffer tank 41 has an additional volume space. When the temperature changes, the cooling medium will expand and contract. The buffer tank 41 is connected to the main pump inlet pipe 12. The cooling medium enters the buffer tank 41 through the main pump inlet pipe 12. The buffer tank 41 will absorb or replenish the volume change of the cooling medium caused by the temperature change. Thus, the buffer tank 41 can buffer the volume change of the cooling medium caused by the temperature change.

[0052] When the cooling medium in the main circulation pipeline is lost due to a small amount of leakage or electrolysis, nitrogen cylinder 42 releases nitrogen gas. The nitrogen gas flows through nitrogen pipeline 43 to buffer tank 41, increasing the pressure at the top of buffer tank 41. This forces additional cooling medium into the main circulation pipeline, thereby maintaining the pressure in the main circulation pipeline and ensuring it is full of cooling medium.

[0053] In some embodiments, the cooling system power circulation device further includes a base support module, which includes a base, a nitrogen cylinder support, a main pump inlet / outlet support, and a pipeline support. All supports are bolted to the base. The main pump module 10 is bolted to the base. The cooling device inlet pipeline 21 is mounted on the main pump inlet / outlet support via pipe clamps and pipe seats. The cooling device outlet pipeline 22 and the cooled device liquid supply pipeline 31 are mounted on the pipeline support via pipe clamps and pipe seats. The buffer tank 41 is bolted to the base. The nitrogen cylinder 42 is fixed to the nitrogen cylinder support via a clamp. The nitrogen pipeline 43 is fixed to the nitrogen cylinder support via pipe clamps and pipe seats. The nitrogen cylinder support is located on the periphery of the base, facilitating operator replacement of the nitrogen cylinder 42 and equipment maintenance.

[0054] In some embodiments, the cooling system power circulation device further includes an instrumentation module 91, which is used to control or monitor the status of the buffer voltage regulator module 40.

[0055] according to Figure 1As shown, in one embodiment of this application, the cooling system power circulation device further includes a filter module 50. The filter module 50 includes a second filter 51 and a filter pipe 52. The filter pipe 52 is disposed between the cooling device outlet pipe 22 and the cooling device liquid supply pipe 31. One end of the filter pipe 52 is connected to the cooling device outlet pipe 22, and the other end of the filter pipe 52 is connected to the cooling device liquid supply pipe 31. The second filter 51 is disposed in the filter pipe 52 and is used to isolate impurities in the cooling medium to prevent impurities from entering the cooling device.

[0056] In some embodiments, the filter element of the second filter 51 is set to a filter element precision of 100 μm, and the filter element is a stainless steel filter element with standard mesh size and low water resistance.

[0057] In some embodiments, the cooling system power circulation device further includes an instrumentation module 91 for monitoring the status of the filter module 50.

[0058] according to Figure 1 As shown, in one embodiment of this application, the filter module 50 further includes a differential pressure gauge, which is installed on the second filter 51. The differential pressure gauge is used to detect the pressure difference on both sides of the second filter 51. When the absolute value of the differential pressure gauge is too large, that is, when there is too much dirt in the second filter 51, the operator can determine whether the second filter 51 needs to be replaced or cleaned based on the data of the differential pressure gauge.

[0059] according to Figure 1 and Figure 2 As shown, in one embodiment of this application, the cooling system power circulation device further includes a degassing module 60. The degassing module 60 includes a degassing tank 61 and a degassing tank pipeline 62. The degassing tank 61 is equipped with an automatic exhaust valve 63. One end of the degassing tank pipeline 62 is connected to the main pump inlet pipeline 12, and the other end of the degassing tank pipeline 62 is connected to the degassing tank 61. The cooling medium enters the degassing tank 61 through the degassing tank pipeline 62, and the degassing tank 61 discharges the gas in the cooling medium. The automatic exhaust valve 63 is used to discharge the gas in the degassing tank 61, thereby completely removing the gas from the cooling medium.

[0060] according to Figure 1 and Figure 2As shown, in one embodiment of this application, the degassing module 60 further includes a heater 64, which is disposed on the degassing tank 61. The heater 64 is used to heat the cooling medium. When the cooling system's power circulation device is started and the ambient temperature is too low, the cooling medium may be at risk of condensation. At this time, the heater 64 is activated to heat the cooling medium, ensuring the continuous flow of the cooling medium in the main circulation pipeline. In addition, when the temperature of the cooling medium is lower than the dew point temperature of the cooled device, condensation may occur on the surface of the pipeline and equipment. The heater 64 also needs to be activated to heat the cooling medium and prevent condensation. During the activation of the heater 64, the main pump 11 remains running to ensure the continuous flow of the cooling medium in the main circulation pipeline.

[0061] In some embodiments, heater 64 is configured as an electric heater. In some embodiments, there are two heaters 64.

[0062] according to Figure 1 As shown, in one embodiment of this application, the cooling system power circulation device further includes a check module 70. The check module 70 includes a check valve 71 and a check pipe 72. The check pipe 72 is disposed between the main pump outlet pipe 13 and the cooling device inlet pipe 21. One end of the check pipe 72 is connected to the main pump outlet pipe 13, and the other end of the check pipe 72 is connected to the cooling device inlet pipe 21. The check valve 71 is disposed in the check pipe 72 and is used to prevent the cooling medium in the cooling device inlet pipe 21 from flowing back, thereby ensuring the normal operation of the cooling system power circulation device.

[0063] according to Figure 1 and Figure 2 As shown, in one embodiment of this application, the cooling system power circulation device further includes a main pump standby module, which is connected in parallel with the main pump module 10. The main pump module 10 is used for daily operation, and the main pump standby module serves as a backup module to ensure the reliability and continuity of the cooling system power circulation device. When the main pump module 10 fails or requires maintenance, the main pump standby module can be quickly switched on to prevent the cooling system power circulation device from being interrupted due to the main pump 11 stopping.

[0064] In daily use, the main pump module 10 and the main pump standby module can be switched periodically according to the operating time or status of the main pump 11 to achieve load balancing and avoid excessive wear caused by prolonged operation of a single main pump 11. When an abnormality is detected in the operating module, the standby module can automatically start operation to ensure the stability of the cooling system's power circulation device.

[0065] The parallel configuration also allows the main pump module 10 and the main pump standby module to operate simultaneously under increased load conditions, providing greater flow and power to meet the demands of high-load operating conditions. This not only improves the reliability of the cooling system's power circulation device but also enhances its ability to adapt to various operating conditions, providing higher stability and maintainability.

[0066] according to Figure 1 and Figure 2 As shown, in one embodiment of this application, the cooling system power circulation device further includes a pipe sealing module 80, which is installed on the cooling device inlet pipe 21, the cooling device outlet pipe 22, the cooled device liquid supply pipe 31, and the cooled device liquid return pipe 32. When the cooling system power circulation device is not in use, the pipe sealing module 80 installed on the cooling device inlet pipe 21, the cooling device outlet pipe 22, the cooled device liquid supply pipe 31, and the cooled device liquid return pipe 32 can effectively prevent external impurities or foreign objects from entering the pipes, ensuring the cleanliness of the cooling system power circulation device and the integrity of the pipes.

[0067] according to Figure 1 and Figure 2 As shown, in one embodiment of this application, the cooling system power circulation device further includes an instrument module 91, an electrical box module 92, and a safety switch box module 93. The instrument module 91 is used to monitor the status of the main pump module 10 in real time. The electrical box module 92 is used to provide stable power to the cooling system power circulation device. The safety switch box module 93 is used to control the switching of the entire cooling system power circulation device. In case of danger, the operator can quickly cut off the power supply and shut down the entire cooling system power circulation device through the safety switch box module 93 to ensure the operator's personal safety.

[0068] In some embodiments, the cooling system power circulation device further includes a base support module, which includes a base, an electrical box support, a main pump inlet / outlet support, and a pipeline support. All supports are bolted to the base. The main pump module 10 is bolted to the base. The cooling device inlet pipeline 21 is mounted on the main pump inlet / outlet support via pipe clamps and pipe seats. The cooling device outlet pipeline 22 and the cooled device liquid supply pipeline 31 are mounted on the pipeline support via pipe clamps and pipe seats. The electrical box module 92 is bolted to the electrical box support, and the safety switch box module 93 is bolted to the main pump inlet / outlet support.
