Description

Technical Field

[0001] The present invention relates to the technical field of fusion devices, and in particular to a vacuum chamber rupture jet experimental system in a fusion device. Background Art

[0002] During high-parameter, long-pulse experiments in fusion devices, the interaction between plasma and the device's inner walls generates a significant amount of heat, causing component temperatures to rise sharply, leading to melting and cracking. Once these internal components begin to melt and crack, they can trigger internal vacuum dehydration, leading to increased vacuum pressure and serious impacts on the device's operational safety. The primary factor influencing vacuum pressure changes is the heat and mass transfer characteristics of the cooling water in the internal vacuum. Exploring effective suppression measures is crucial to ensuring the safe operation of high-parameter plasmas in fusion devices.

[0035] like Figures 1 to 4 As shown, the present invention proposes a fusion device vacuum chamber rupture jet experimental system, which includes a circulating water system, a jet water system, a vacuum tank system, and a control and data acquisition system 30. Each system is described in detail below.

[0036] Among them, the circulating water system is used to provide circulating water, including a centrifugal pump 1, a simulated internal rupture branch and a simulated circulating water branch. The input end of the centrifugal pump 1 is connected to a water tank 2, which is used to store water. The output end of the water tank 2 is connected to a pipeline filter (not shown) for removing impurities. The output end of the centrifugal pump 1 is fixedly connected to a first check valve 3, and the simulated internal rupture branch is fixedly connected to a first manual regulating valve 6. The simulated internal rupture branch is also connected to a first pressure transmitter 5 and a first electromagnetic flowmeter 4. The simulated circulating water branch is fixedly connected to a second pressure transmitter 8, a third pressure transmitter 9 and a second electromagnetic flowmeter 7. A second check valve 10 is provided between the second pressure transmitter 8 and the third pressure transmitter 9.

[0037] A second manual regulating valve 11 and a third manual regulating valve 12 are located on the side of the second electromagnetic flowmeter 7 remote from the second pressure transmitter 8. A pneumatic shut-off valve 13 is located on the side of the third manual regulating valve 12. This pneumatic shut-off valve 13 is DN40, has a nominal pressure of 4.0 MPa, and an allowable operating temperature range of -20-200°C. It is connected via a flange and has an actuation pressure of 0.5 MPa. A first high-pressure gas tank 15 is connected to the side of the pneumatic shut-off valve 13 remote from the third manual regulating valve 12. A third electromagnetic flowmeter 14 is located on the side of the pneumatic shut-off valve 13 remote from the third manual regulating valve 12. The circulating water system simulates the flow conditions of normal circulating water within a fusion device and those under internal breach conditions, enabling effective regulation and monitoring of water pressure and flow, providing diverse experimental conditions for studying the heat and mass transfer characteristics of cooling water in an internal vacuum.

[0038] Secondly, the jet water system is used to generate a cooling water jet, including a stainless steel pipeline and a pneumatic bellows-sealed valve 19 connected thereto. The pneumatic bellows-sealed valve 19 has a nominal pressure of 3.0 MPa, an allowable operating temperature of 80°C, an opening time of ≤2s, and a driving air pressure of 0.8 MPa. It is connected using a threaded joint. One end of the pneumatic bellows-sealed valve 19 is connected to a second high-pressure gas tank 18. The stainless steel pipeline is connected between the second manual regulating valve 11 and the third manual regulating valve 12. The stainless steel pipeline is provided with a fourth electromagnetic flowmeter 16 and a fourth pressure transmitter 17.

[0039] In this embodiment, the fourth electromagnetic flowmeter 16 and the fourth pressure transmitter 17 are both located on the side of the pneumatic bellows-sealed valve 19 away from the vacuum tank 25. The stainless steel pipe has an inner diameter of 13-14 mm. The downstream end of the stainless steel pipe is connected to the vacuum tank 25 via a nozzle 33. The inner diameter of the stainless steel branch pipe is preferably 14 mm. The valve dynamic pressure of the pneumatic bellows-sealed valve 19 is 0.5 MPa. The jet water system generates a stable cooling water jet, which enters the vacuum tank 25 through the stainless steel pipe and nozzle 33. This facilitates the study of related phenomena under different jet parameters and contributes to the research on the physical mechanisms of the vacuum dehydration process.

[0040] In addition, the vacuum tank system is used to create a vacuum environment, including a vacuum tank 25, which is connected to a vacuum pump 28. The vacuum pump 28 has a pumping speed of 25l / s at 50Hz and a limit pressure of 2.0Pa. The vacuum tank 25 is connected to a vacuum gauge 20, a fifth pressure transmitter 21, and a temperature transmitter 22. A pressure relief tank 24 is connected to one side of the vacuum tank 25, and a first manual baffle valve 23 is connected between the vacuum tank 25 and the pressure relief tank 24. A collection tank 27 is connected to one side of the vacuum tank 25, a second manual baffle valve 26 is connected between the vacuum tank 25 and the collection tank 27, and a third manual baffle valve 29 is connected between the vacuum tank 25 and the vacuum pump 28.

[0041] The vacuum tank 25 is equipped with a pressure relief port 32 connected to the pressure relief tank 24, a vacuum gauge interface 32, a vacuum pump interface 34, a drain port 35 at the bottom of the vacuum tank 25, and two sets of organic glass observation windows 36. The vacuum tank system is used to create a vacuum environment that meets experimental requirements and can monitor environmental parameters within the vacuum tank in real time, ensuring experimental safety while meeting the requirements of material collection and pressure regulation during the experiment.

[0042] Finally, the control and data acquisition system 30 is used to collect, monitor and store experimental data in real time. It includes multiple sets of temperature transmitters, pressure transmitters and electromagnetic flow meters installed in the circulating water system, jet water system and vacuum tank system. It also includes a computer for remote control and real-time monitoring. The control core of the computer adopts Siemens S7 series PLC, and the software is preferably Wincc configuration human-machine interface.

[0043] In order to verify the technical effect of the present invention, an experiment was conducted on a vacuum chamber breach jet experimental system in a fusion device.

[0044] Preparation before the experiment

[0045] Test bench test: monitor the pressure and temperature of the circulating water system, monitor the water flow of the jet water system, and monitor the vacuum pressure of the vacuum tank system. The test results are as follows: Figure 5 shown.

[0046] Among them, when monitoring the pressure and temperature of the circulating water system, the outlet pressure of centrifugal pump 1 was tested and checked to ensure that it could start and operate normally. The rated head of centrifugal pump 1 was 300 meters and the rated flow rate was 100 m³ / h. The pump outlet pressure of centrifugal pump 1 was tested and the inverter frequency was measured to be 47 Hz and the pump outlet pressure was 3.0 MPa. When monitoring the temperature of the circulating water system, the outlet temperature of centrifugal pump 1 was tested and measured to be 70°C. At the same time, the connected water tank 2 was cleaned and filled with water, and the water level was maintained at an appropriate height to avoid cavitation in the water pump. At the same time, the pipeline filter at the outlet of water tank 2 was checked to ensure that it was not blocked.

[0047] In addition, the water flow monitoring of the jet water system includes the following steps: checking the stainless steel branch pipe and the pneumatic bellows sealing valve 19 in the jet water system to ensure that the inside of the stainless steel branch pipe is smooth and free of foreign matter, the pneumatic bellows sealing valve 19 is flexible, and its connection with the second high-pressure gas tank 18 is tight and leak-free, the valve dynamic pressure of the pneumatic bellows sealing valve 19 is set to 0.5MPa, and the opening time does not exceed 2 seconds. The flow rate of the jet water system is tested and the measured flow rate of the jet water system is 3.78 , and prepare nozzles 33 of different diameters so that they can be replaced as needed in subsequent experiments;

[0048] Finally, when monitoring the vacuum pressure of the vacuum tank system, the pressure inside the vacuum tank 25 is detected, the vacuum pump 28 is turned on, and the changes in the readings of the vacuum gauge 20 are observed. The average experimental pressure is measured to be 1000 Pa, and the first manual baffle valve 23, the second manual baffle valve 26 and the third manual baffle valve 29 are checked to ensure that their switches are normal.

[0049] 2. Experimental Procedure

[0050] Establishing a vacuum environment: Open the third manual flapper valve 29 , and keep the pneumatic bellows sealing valve 19 , the first manual flapper valve 23 , and the second manual flapper valve 26 closed.

[0051] Start the vacuum pump 28 and reduce the pressure in the vacuum tank 25 to the target pressure of 1000 Pa. During the pressure reduction process, the pressure change is monitored in real time through the vacuum gauge 20 and the fifth pressure transmitter 21. When the target pressure is reached, close the vacuum pump 28 and the third manual baffle valve 29, and maintain the vacuum pressure for 5 minutes. If the pressure rises significantly during this period, it indicates that there is a leak in the system. It is necessary to carefully check the sealing conditions of each connection part and valve, and repeat the vacuum operation after repair.

[0052] Circulating water system adjustment: open the first manual regulating valve 6, the second manual regulating valve 11, and the third manual regulating valve 12, and start the centrifugal pump 1. At this time, the first check valve 3 at the output end of the centrifugal pump 1 is used to prevent water backflow. By adjusting the opening of the first manual regulating valve 6 and the third manual regulating valve 12 and the water pump frequency, while observing the readings of the first pressure transmitter 5, the first electromagnetic flowmeter 4, the second electromagnetic flowmeter 7, and the third electromagnetic flowmeter 14, until the water spray system pressure reaches the target pressure.

[0053] Jet experiment process: open the pneumatic shut-off valve 13, so that the air supply channel of the first high-pressure gas tank 15 connected to the pneumatic shut-off valve 13 is opened, and the high-pressure gas drives the pneumatic bellows sealing valve 19 to open quickly, and the cooling water jet flows from the stainless steel branch pipe through the nozzle 33 into the vacuum tank 25. At this time, a camera is used to record the water jet process. At the same time, the temperature transmitter 22, the fifth pressure transmitter 21 installed on the vacuum tank 25, and the fourth pressure transmitter 17 and the fourth electromagnetic flowmeter 16 in the jet water system are used to collect the temperature, pressure and flow data in the vacuum tank and during the jet process in real time, and the data are stored and analyzed by the computer in the data acquisition and storage system. After a period of jet experiment, the pneumatic shut-off valve 13 is closed, the air supply is cut off, and the pneumatic bellows sealing valve 19 is returned to its seat, the water jet is ended, and the single jet experiment is completed. The system parameter response in the vacuum jet experiment is as follows Figure 6 shown.

[0054] Post-experimental processing: After the jet experiment is completed, first open the first manual damper valve 23 to balance the pressure in the vacuum tank 25 with the ambient pressure to prevent danger caused by pressure difference in subsequent operations; then open the second manual damper valve 26 to drain the accumulated water in the vacuum tank into the collection tank 27, and finally open the rear flange of the vacuum tank 25 to clean the inner wall and remove any remaining impurities and moisture to prepare for the next round of experiments.

[0055] 3. Data Collection and Analysis

[0056] During the entire experimental process, the control and data acquisition system 30 continues to work, and the computer in the control and data acquisition system 30 records the data from various sensors in real time, including the pressure, flow and temperature data of different branches of the circulating water system, the jet pressure and flow data of the jet water system, and the vacuum pressure and temperature data in the vacuum tank system. After the experiment, the collected data is analyzed.

[0057] The above specific embodiments are merely several optional embodiments of the present invention.
