DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] The embodiment of the present application provides a test device for a secondary-side passive residual heat removal system, which can solve the problem in the related art that the working capacity of the secondary-side passive residual heat removal system cannot be accurately measured.

[0032] See also Figure 1 In order to solve the above problems, the present application provides a test device for a secondary side passive waste heat removal system, which includes a swing platform 1, a steam generator simulation body 2, a main heat dissipation circuit 3, a backup heat dissipation circuit 4 and a water tank simulation body 5, the steam generator simulation body 2 is arranged on the swing platform 1; the two ends of the main heat dissipation circuit 3 are respectively connected to the steam outlet and the condensate inlet of the steam generator simulation body 2, and are used to dissipate the heat of the steam generator simulation body 2; the two ends of the backup heat dissipation circuit 4 are respectively connected to the steam outlet and the condensate inlet of the steam generator simulation body 2, and are used to dissipate the heat of the steam generator simulation body 2 when the main heat dissipation circuit 3 stops working; the water tank simulation body 5 simulates the cooling water tank of the ship, and is used to dissipate the heat of the backup heat dissipation circuit 4.

[0033] The swing platform 1 is a swinging working platform, and its specific principle can refer to a seesaw. Its main function is to simulate the swinging motion of a marine vessel, which will not be explained in detail here.

[0034] When a nuclear-powered ship is sailing and the steam generator loses water supply, the secondary side passive residual heat removal system automatically starts to operate, using the natural circulation formed by the density difference between the cold section and the hot section in the system to remove heat from the secondary side of the steam generator for a long time. Unlike land-based reactors, ships are subject to typical marine conditions such as wind, waves, and surges when sailing. Marine conditions acting on the ship will cause additional acceleration in the reactor unit, causing periodic fluctuations in pressure, flow, and temperature in the secondary side passive residual heat removal system, affecting the working capacity of the secondary side passive residual heat removal system. In order to verify whether the secondary side passive residual heat removal system can meet its design requirements and operate normally under marine conditions, the present application proposes a test device that can simulate the secondary side passive residual heat removal system.

[0035] Among them, the main heat dissipation circuit 3 simulates the secondary side operation circuit, and the backup heat dissipation circuit 4 simulates the passive waste heat discharge circuit, that is, the present application provides a test device for the secondary side passive waste heat discharge system, which includes a swing platform 1, a steam generator simulation body 2, a secondary side operation circuit, a passive waste heat discharge circuit and a water tank simulation body 5. The steam generator simulation body 2 is arranged on the swing platform 1; the two ends of the secondary side operation circuit are respectively connected to the steam outlet and the condensate inlet of the steam generator simulation body 2 to simulate the operation process of the secondary circuit side; the two ends of the passive waste heat discharge circuit are respectively connected to the steam outlet and the condensate inlet of the steam generator simulation body 2, and are used to discharge the heat generated by the steam generator simulation body 2 when the secondary side operation circuit stops working; the water tank simulation body 5 is used to cool the passive waste heat discharge circuit. The test device for the secondary side passive waste heat discharge system in the present application can simulate ocean conditions and detect the heat discharge capacity of the secondary side passive waste heat discharge system during the swinging of the swing platform.

[0036] When the ship is operating normally in the ocean, the steam generator simulation body 2 is cooled through the main heat dissipation circuit 3. When the ship fails in the ocean, the secondary side water supply of the ship is lost. In order to discharge the core waste heat in time, it is necessary to start the secondary side passive waste heat discharge system to reduce the temperature and pressure in the steam generator. That is, in this application, the main heat dissipation circuit 3 does not work, and the heat is dissipated through the backup heat dissipation circuit 4. At this time, the steam generator simulation body 2 is always generating heat, and the heat is exchanged through the backup heat dissipation circuit 4 and the water tank simulation body 5, so that the water temperature in the water tank simulation body 5 increases.

[0037] In the present application, the main purpose of setting up the main heat dissipation circuit 3 is mainly because, when a problem occurs in an actual ship, the steam is directly switched from the main heat dissipation circuit 3 to the backup heat dissipation circuit 3. Therefore, the main heat dissipation circuit 3 is designed to simulate the instantaneous changes when a ship fails as much as possible in order to obtain more prepared test data.

[0038] In the specific test process, the steps are as follows:

[0039] a) Establish a test device for the secondary side passive residual heat removal system under marine conditions;

[0040] b) Complete the high-voltage and low-voltage commissioning of the test simulation device;

[0041] c) According to the test conditions, the initial conditions of the system loop are established, including the water level of the water tank simulation body 5, the water temperature of the water tank simulation body 5, the pressure in the steam generator simulation body 2, and the steam temperature in the steam generator simulation body 2 (the water temperature and the steam temperature can be heated by a heater, the water level can be measured by a water level gauge, and the pressure can also be obtained by a pressure sensor. This is a prior art, so no further explanation is given here);

[0042] d) When the steam temperature and pressure of the simulated body of the steam generator reach the predetermined values, the backup heat dissipation circuit 4 is opened and the main heat dissipation circuit 3 is closed at the same time to establish the secondary side natural circulation;

[0043] e) causing the swing platform to rotate;

[0044] f) When the water tank simulates the boiling of water in the body for five minutes, the heating is stopped so that the swing table no longer rotates, and the main heat dissipation circuit 3 is opened so that the main heat dissipation circuit 3 cools the steam;

[0045] g) During the test, the measurement system will automatically record the pressure, temperature, flow, water level and other data of each measuring point, which will be used as test data for analysis and processing;

[0046] h) Analyze the data obtained from the experiment and draw conclusions from the experimental research.

[0047] In this process, after the water boils, if the measured pressure, degree, flow, water level and other data remain constant, it means that the heat dissipation effect of the backup heat dissipation circuit 4 can meet the heat dissipation of the reactor when a failure occurs in the actual ship. If not, it means that the backup heat dissipation circuit 4 is relatively poor and does not meet the actual use of the ship. Therefore, the test device of the secondary side passive residual heat removal system of this application has good practical guiding significance.

[0048] It should be understood that the steam generator simulation body 2 in the embodiment of the present invention includes a lower head fixed to the swing table 1, and the upper part of the lower head is fixed with the second lower cylinder and the first lower cylinder in sequence from bottom to top, the first lower cylinder is nested in the inner wall of the second lower cylinder, and the second lower cylinder is connected to the first lower cylinder. The upper cylinder is fixed to the upper part of the first lower cylinder, and the upper cylinder and the first lower cylinder are sealed by a sealing plate; the upper part of the upper cylinder is connected to the upper head, and the outer wall of the upper head is provided with a steam outlet pipe and a safety valve pipe connected to the interior of the upper head, and the bottom of the lower head [specifically the side opening of the bottom] is provided with a drain pipe [for drainage].

[0049] The cylinder wall of the upper cylinder is evenly provided with at least one water supply pipe for water injection, and each water supply pipe is connected to the interior of the upper cylinder. A heating assembly for heating water to produce steam and water is provided in the first lower cylinder; a steam riser is provided in the upper cylinder, and a perforated plate for steam-water separation is provided in the steam riser, and the size of the perforated plate corresponds to the internal resistance coefficient of the steam generator when in use. The lower opening of the steam riser is connected to the first lower cylinder. The test simulation body also includes at least one condensate return pipe evenly provided along the outer wall of the upper cylinder; the inlet of the condensate return pipe is connected to the upper cylinder, and the outlet is connected to the second lower cylinder.

[0050] The working mode of the above-mentioned test simulation body is: when the steam generator simulation body 2 is in use, water is injected through the water supply pipe and flows to the heating component through the condensate return pipe for heating to form a steam-water mixture. The steam-water mixture is separated into steam and water through the steam rising channel and the orifice plate inside it. The steam is discharged through the steam outlet pipe, and the condensate is returned through the condensate return pipe for reheating.

[0051] It is understandable that the steam generator simulation body 2 may also adopt other simulation bodies in the prior art, as long as it can play the same role, so no further explanation is given.

[0052] Furthermore, the main heat dissipation circuit 3 includes a main heat dissipation pipeline and a first steam pipeline solenoid valve 31, a first heat exchanger simulation body 32 and a first condensate pipeline stop valve 33 arranged on the main heat dissipation pipeline according to the steam flow direction. When the first steam pipeline solenoid valve 31 and the first condensate pipeline stop valve 33 are closed, the main heat dissipation circuit 3 stops working.

[0053] When a fault occurs during the actual sailing of the ship, all power is cut off, so the entire main heat dissipation circuit 3 does not work. In the present application, the main heat dissipation circuit 3 is made to stop working by turning off the first steam pipe solenoid valve 31 and the first condensate pipe stop valve 33.

[0054] When the steam generator simulation body 2 is cooled, it is also achieved through the heat exchange effect of the first heat exchanger simulation body 32. After the steam is condensed by heat exchange, it enters the steam generator simulation body 2 again through the first condensate pipe stop valve 33.

[0055] Specifically, the backup heat dissipation circuit 4 includes a backup heat dissipation pipeline and a second steam pipeline solenoid valve 41, a second heat exchanger simulation body 42 and a second condensate pipeline solenoid valve 43 arranged on the backup heat dissipation pipeline according to the steam flow direction, wherein the second heat exchanger simulation body 42 is located in the water tank simulation body 5. When the second steam pipeline solenoid valve 41 and the second condensate pipeline solenoid valve 43 are closed, the backup heat dissipation circuit 4 stops working.

[0056] The second heat exchanger simulation body 42 is located in the water tank simulation body 5. Through the heat exchange effect of the water tank simulation body 5, the steam flowing through the second heat exchanger simulation body 42 is cooled and condensed into water. When the main heat dissipation circuit 3 is in normal use, the second steam pipe solenoid valve 41 and the second condensate pipe solenoid valve 43 are closed. When the main heat dissipation circuit 3 is not working, the second steam pipe solenoid valve 41 and the second condensate pipe solenoid valve 43 are quickly opened to ensure that the backup heat dissipation circuit 4 is in working condition in time.

[0057] In the present application, water for realizing the heat dissipation function of the second heat exchanger simulation body 42 and the water tank simulation body 5 can be supplied by an external water source or by a water tank on a simulated ship. In order to simulate the ship environment as much as possible and to facilitate the test setting, a water supply tank 6 is provided in the present application, and the water supply tank 6 has a water outlet pipeline and a water return pipeline;

[0058] The first heat exchanger simulation body 32 has a cooling water inlet and a cooling water outlet, the cooling water inlet is connected to the water outlet pipeline, and the cooling water outlet is connected to the water return pipeline;

[0059] and / or,

[0060] The water outlet pipeline has a third branch 7 , the other end of the third branch 7 is communicated with the water tank simulation body 5 , and a third water supply pipeline stop valve 8 is provided on the third branch 7 .

[0061] It should be understood that a water replenishment pump should be provided in the water outlet pipeline to achieve a rapid water replenishment function.

[0062] On the basis of the previous embodiment, the water outlet pipeline has a first branch 9 , the first branch 9 is connected to the cooling water inlet, and a first water supply pipeline stop valve 10 is provided on the first branch 9 .

[0063] In the previous embodiment, the water outlet pipeline has a second branch 20 , and the second branch 20 is used to transport water to the steam generator simulation body 2 . The second water supply pipeline stop valve 30 is provided on the second branch 20 .

[0064] It should be understood that in the present application, the water supply tank 6 is an external device. Therefore, when the swing platform 1 rotates, the water supply tank 6 does not move. Therefore, there needs to be a hose section on the water outlet pipe and the return pipe connected to the water supply tank 6 to prevent the pipe from being damaged during the rotation of the swing platform 1, thereby reducing the service life of the test device.

[0065] In the present application, in order to conveniently control the amplitude and frequency of the rocking platform 1 to achieve experimental data under different marine environments, the test device also includes a driving device 40, which is connected to the rocking platform 1 and is used to drive the rocking platform 1 to rotate.

[0066] On the basis of the previous embodiment, the driving device 40 adopts a hydraulic device;

[0067] The test device further includes a hydraulic oil tank 50, and the hydraulic oil tank 50 is used to supply oil to the hydraulic device and receive return oil from the hydraulic device.

[0068] The driving device 40 is connected to one end of the swing platform 1 and realizes the swing function by driving the end to rise or fall.

[0069] In the present application, the driving device 40 adopts a hydraulic device, which drives the rocking platform 1 to rotate by extending and retracting the piston rod.

[0070] Furthermore, a third heat exchanger simulation body 60 is disposed in the hydraulic oil tank 50;

[0071] The water outlet pipeline has a fourth branch 70 , the other end of the fourth branch 70 is connected to the water replenishment tank 6 , and the third heat exchanger simulation body 60 is also located on the fourth branch 70 .

[0072] During the actual operation, since the hydraulic oil tank 50 will also sway with the waves, a large amount of heat will accumulate inside it. Therefore, in the test device in the present application, a third heat exchanger simulation body 60 is also provided. When the water in the water supply tank 6 flows through the third heat exchanger simulation body 60, the temperature of the hydraulic oil tank 50 is transferred to the water through the principle of heat exchange, thereby reducing the temperature of the hydraulic oil tank 50 itself.

[0073] Furthermore, an exhaust valve 80 is provided at the highest point of both the main heat dissipation circuit 3 and the backup heat dissipation circuit 4 .

[0074] See also Figure 1 In the actual ship driving process, the reactor heat dissipation pipeline is always in a steam environment. Therefore, in order to simulate the actual heat dissipation process as much as possible, it is necessary to exhaust the air in the main heat dissipation loop 3 and the backup heat dissipation loop 4.

[0075] In the present application, a test device for a secondary side passive residual heat removal system is provided, which specifically includes the following steps:

[0076] a) Establish a test and research device for the secondary side passive residual heat removal system under marine conditions;

[0077] b) Complete the high-voltage and low-voltage commissioning of the test simulation device;

[0078] c) According to the test conditions, establish the initial conditions of the system loop, including the water level of the water tank simulation body 5, the water temperature of the water tank simulation body 5, the pressure in the steam generator simulation body 1, and the steam temperature in the steam generator simulation body 1;

[0079] d) When the steam temperature and pressure of the steam generator simulation body 1 reach the predetermined values, the second steam pipeline solenoid valve 41 and the second condensate pipeline solenoid valve 43 are opened at the same time, and the first steam pipeline solenoid valve 31 and the first condensate pipeline solenoid valve 33 are closed to establish the secondary side natural circulation;

[0080] e) Open the stop valve 8 of the third water supply pipeline, set the swing cycle and swing amplitude by setting the output of the hydraulic oil, and start the swing platform 1;

[0081] f) When the water in the water tank simulation body 5 boils for five minutes, the heating is stopped, the swing platform 1 is closed, and in order to achieve rapid cooling, the first steam pipeline solenoid valve 31 and the first condensate pipeline solenoid valve 33 are opened to allow the circuit to cool through the first heat exchanger simulation body 32;

[0082] g) During the test, the measurement system will automatically record the pressure, temperature, flow, water level and other data of each measuring point, which will be used as test data for analysis and processing;

[0083] h) Analyze the data obtained from the experiment and draw conclusions from the experimental research.

[0084] After the test device is debugged, verification tests of various factors can be carried out according to the selection of test conditions.
