Those skilled in the art can understand the specific meaning of the above terms in this application depending on the specific circumstances.

[0023] like Figure 1-4 As shown, a generator cooling water intelligent purification system includes a cooling water control cabinet 100, a cooling water tank 200, and an intermediate water tank 300. The cooling water control cabinet 100 has an ammonia-added inlet pipe 1 and an ammonia-added pre-inlet pipe 2. The cooling water tank 200 is connected to the outlet of the cooling water control cabinet 100 through a water replenishment pipe 3. The inlet of the intermediate water tank 300 is connected to the overflow outlet of the cooling water tank 200 through an overflow pipe 4.

[0024] refer to Figure 2 The constant cooling water control cabinet 100 includes a cabinet body 5, a conductivity meter 6 mounted on the cabinet body 5, an electric regulating valve 7 mounted on the ammonia-adding inlet water line 1, an ammonia-adding pre-adjusting valve 8 mounted on the ammonia-adding pre-water line 2, a mixer 9 connected to the outlet of the ammonia-adding inlet water line 1 and the outlet of the ammonia-adding pre-water line 2, a makeup water line 3 connected to the outlet of the mixer 9, a sampling line 10 connected to the mixer 9, and an electrode flow cell 11 mounted on the sampling line 10 and electrically connected to the conductivity meter 6. It can be understood that the ammonia-adding inlet water line 1 is used to flow condensate after ammonia addition, and the ammonia-adding pre-water line 2 is used to flow condensate or demineralized water.

[0025] The control unit 12 is electrically connected to the conductivity meter 6, the electric regulating valve 7, and the ammonia pre-addition adjustment valve 8. The control unit 12 controls the opening degree of the electric regulating valve 7 and the ammonia pre-addition adjustment valve 8 based on the comparison between the actual conductivity value detected by the conductivity meter 6 and the preset conductivity value.

[0026] In this invention, by monitoring the conductivity in real time and automatically adjusting the opening of the electric regulating valve 7 and the ammonia-adding regulating valve 8 based on the comparison between the actual measured value and the preset value, the water quality of the constant cooling water (i.e., controlling the pH value of the water) can be precisely controlled, ensuring that the conductivity of the cooling water inside the generator is always kept within the optimal range, thereby effectively inhibiting copper corrosion and extending the service life of the equipment.

[0027] Furthermore, the system's automated control unit 12 can automatically adjust based on the data from the conductivity table 6, reducing the need for manual intervention, improving operational efficiency and system response speed, and also reducing the risk of operational errors due to human error. The design of the intermediate water tank 300 and its connection method with the overflow pipe 4 between it and the fixed cooling water tank 200 ensure that water waste can be effectively avoided even under abnormal conditions, and that the entire system can maintain stable operation.

[0028] Referring to 2 or 3, in some embodiments, the constant cooling water control cabinet 100 further includes a sampling flow meter 13, which is disposed in the sampling pipeline 10 and electrically connected to the control unit 12, and is arranged upstream of the electrode flow cell 11.

[0029] In this invention, the sampling flow meter 13 is positioned upstream of the electrode flow cell 11, ensuring that the water sample flowing through the electrode flow cell 11 has a stable and known flow velocity, which helps improve the accuracy of conductivity measurement. By monitoring and adjusting the water flow velocity in the sampling pipeline 10, the control system can adjust the sampling rate according to actual needs, thereby optimizing the response time of the entire system.

[0030] In some embodiments, the constant cooling water control cabinet 100 further includes a sampling inlet valve 25, which is disposed in the sampling pipeline 10 and electrically connected to the control unit 12, and is arranged upstream of the sampling flow meter 13.

[0031] In some embodiments, the constant cooling water control cabinet 100 further includes a sampling outlet valve 14, which is disposed in the sampling pipeline 10 and electrically connected to the control unit 12, and is arranged downstream of the electrode flow cell 11.

[0032] In this invention, the sampling outlet valve 14 is located downstream of the electrode flow cell 11, allowing the system to discharge or circulate the measured water sample back into the system when needed, providing greater flexibility for operators. By controlling the on / off state of the sampling outlet valve 14, the water flow path and flow rate through the electrode flow cell 11 can be effectively managed, thereby ensuring the stability of the water flow during water quality monitoring and helping to obtain accurate and reliable conductivity measurement data.

[0033] In some embodiments, the constant cooling water control cabinet 100 further includes a front shut-off valve 15, which is disposed in the ammonia-adding water inlet pipe 1 and electrically connected to the control unit 12, and the front shut-off valve 15 is arranged upstream of the electric regulating valve 7.

[0034] In this invention, the upstream shut-off valve 15 can quickly cut off the water flow in the ammonia inlet pipe 1 in emergency situations or during maintenance, ensuring system safety. By setting the upstream shut-off valve 15 upstream of the electric regulating valve 7, the electric regulating valve 7 can be maintained or replaced independently without affecting the normal operation of other components, which not only reduces downtime but also improves the efficiency and safety of maintenance work.

[0035] In some embodiments, the constant cooling water control cabinet 100 also includes a rear shut-off valve 16, which is disposed in the ammonia-adding inlet water pipeline 1 and electrically connected to the control unit 12, and is arranged downstream of the electric regulating valve 7.

[0036] In this invention, the downstream shut-off valve 16 can cut off the water flow from the electric regulating valve 7 to the mixer 9 when necessary, providing an additional layer of safety. By installing the downstream shut-off valve 16 downstream of the electric regulating valve 7, maintenance or replacement of the electric regulating valve 7 and its downstream components can be performed without interrupting the operation of the entire system, which not only reduces downtime but also improves the flexibility and efficiency of maintenance work.

[0037] In some embodiments, the constant cooling water control cabinet 100 further includes a bypass 17 connecting the inlet of the front shut-off valve 15 and the outlet of the rear shut-off valve 16, and a bypass valve 24 disposed in the bypass 17.

[0038] In this invention, by setting a bypass 17 and a bypass valve 24, when a component (such as an electric regulating valve 7) between the front shut-off valve 15 and the rear shut-off valve 16 needs maintenance or malfunctions, the system can be switched to the bypass 17 to continue operating, ensuring that the system will not completely shut down due to a problem with a single component, thereby improving the reliability and stability of the system.

[0039] In some embodiments, the constant cooling water control cabinet 100 also includes a check valve 18, which is disposed in the ammonia inlet water pipeline 2 and arranged upstream of the ammonia inlet regulating valve 8.

[0040] In this invention, the main function of the check valve 18 is to prevent water from flowing in the opposite direction. By placing it upstream of the regulating valve 8 before ammonia addition, it can effectively prevent water from flowing back from the part after ammonia addition to the part before ammonia addition when the system pressure drops or other abnormal conditions occur. This ensures that the chemical agent (such as ammonia) can only flow in one direction, prevents possible contamination and mutual interference within the system, and protects the equipment related to ammonia addition from potential damage.

[0041] In some embodiments, the constant cooling water control cabinet 100 further includes a water supply bypass 19 connected to the water supply pipeline 3, a water supply flow meter 20 installed in the water supply pipeline 3, and an electric valve 21 installed in the water supply pipeline 3, located downstream of the water supply flow meter 20 and electrically connected to the control unit 12.

[0042] In this invention, by setting up a water supply bypass 19, when the main water supply pipeline 3 needs maintenance or malfunctions, water supply can be continued by switching to the water supply bypass 19, ensuring that the system will not be interrupted due to a problem with a single component, and greatly improving the reliability and redundancy of the system.

[0043] The addition of the water supply flow meter 20 enables the system to monitor the water supply flow into the constant cooling water tank 200 in real time, providing accurate data support. Combined with the use of the electric valve 21, the control system can precisely adjust the water supply according to actual needs to maintain the best water level and water quality conditions.

[0044] In some embodiments, the constant cooling water control cabinet 100 also includes a water supply flow bypass valve 26, which is disposed in the water supply bypass 19.

[0045] In some embodiments, the constant cooling water control cabinet 100 further includes a flow meter shut-off valve 22 disposed on the water supply pipeline 3 and located upstream of the water supply flow meter 20 and electrically connected to the control unit 12, and a valve downstream shut-off valve 23 disposed on the water supply pipeline 3 and located downstream of the electric valve 21 and electrically connected to the control unit 12.

[0046] In this invention, by setting a flow meter shut-off valve 22 upstream of the water supply flow meter 20, the shut-off valve can be closed when the water supply flow meter 20 needs to be maintained, calibrated or replaced without stopping the operation of the entire system, which improves the convenience and efficiency of maintenance work and reduces system downtime.

[0047] The downstream shut-off valve 23 is located downstream of the electric valve 21 and can cut off the water flow from the electric valve 21 to the subsequent pipeline section when necessary, providing an additional safety protection layer and ensuring the safe and stable operation of the system.

[0048] refer to Figure 3In some embodiments, the intermediate water tank 300 includes a tank body 30, a float riser 31 disposed in the tank body 30, a float 32 disposed in the float riser 31, a limiting beam 34 disposed corresponding to the float 32, an overflow pipe 35 connected to the overflow pipe 4, and a drain pipe 33 for connecting to the condenser.

[0049] In this invention, the design of the float 32 and float riser 31 enables automatic adjustment of the water level in the intermediate water tank 300. The float 32 floats up and down with changes in the water level, adjusting the amount of water entering or leaving the tank as needed to ensure a stable water level without manual intervention. The overflow pipe 35, connected to the overflow pipe 4, effectively handles excess water when the water level is too high, preventing tank overflow due to unforeseen circumstances. This not only protects the safe operation of the system but also avoids water waste and helps save costs.

[0050] The limiting beam 34 is correspondingly set with the float 32, which can limit the maximum range of movement of the float 32 and prevent equipment damage or other safety hazards caused by excessive rising or falling of the float 32. This design increases the physical safety of the system and ensures long-term stable operation. The drain pipe 33 is used to connect with the condenser, which can flexibly discharge excess water or perform necessary water circulation according to actual needs, improving the flexibility of the entire system and making water quality management and water quantity control more convenient and efficient.

[0051] In summary, through the effective coordination of the above components, the intermediate water tank 300 can maintain good operating condition under different working conditions, enhancing the reliability and stability of the entire generator cooling water intelligent purification system.

[0052] In some embodiments, the purification system further includes a water flushing pipe 40, which is connected to the water supply pipe 3, and a water flushing valve 41 is provided on the water flushing pipe 40.

[0053] In some embodiments, the purification system further includes a drain pipe 50, which is connected to the overflow pipe 4, and a drain valve 51 is provided on the drain pipe 50.

[0054] In some embodiments, an overflow valve 60 is provided on the overflow pipe 4, and a drain valve 70 is provided on the drain pipe 33.

[0055] This invention provides a specific example, see reference. Figure 2The control unit includes a PLC or DCS. The PLC or DCS system automatically adjusts the flow rate of the condensate polishing main pipe after ammonia addition and replenishes the water (or demineralized water) before ammonia addition into the stator cooling water tank 2 in a certain ratio and adjusts the conductivity of the water so that the pH of the generator stator cooling water reaches the optimal anti-corrosion range. This can minimize the copper corrosion of the generator. The pH value is controlled at 8.0-9.0, which can effectively inhibit copper corrosion and prevent copper wire rod deposition and blockage from the source.

[0056] This invention provides another specific example, see reference. Figure 3 Unlike the previous embodiment, the control unit is located at a remote end (control unit 12 is not shown in the figure). The control unit includes a PLC or DCS. The PLC or DCS system automatically adjusts the flow rate of the condensate polishing main pipe after ammonia addition and replenishes the water (or demineralized water) before ammonia addition into the stator cooling water tank 2 in a certain ratio and adjusts the conductivity of the water so that the pH of the generator stator cooling water reaches the optimal anti-corrosion range. This can minimize the copper corrosion of the generator. The pH value is controlled at 8.0-9.0, which can effectively inhibit copper corrosion and prevent copper wire rod deposition and blockage from the source.

[0057] In summary, the beneficial effects of the present invention include: 1) It has an automatic or manual water replenishment function for generator constant cooling water; 2) Overflow water and makeup water samples are automatically recycled back to the condenser, achieving zero discharge; 3) It has an interlocking shutdown protection function when the water replenishment conductivity exceeds the limit; 4) It has a constant liquid level function in the cooling water tank, eliminating the need for manual water replenishment; 5) It has a communication interface with a remote host computer to enable remote monitoring; 6) Real-time monitoring of water supply conductivity and flow rate, with alarms for both conductivity and flow rate exceeding limits; 7) It has remote control function, enabling remote manual and automatic operation.
