Description

Technical Field

[0001] This invention relates to the technical field of thermal-fluid-structure interaction testing equipment for air valves, specifically to a synchronous testing device and method for heat exchange temperature field and structural deformation. Background Technology

[0002] Sodium-cooled fast reactors have been widely promoted and constructed as the mainstream reactor type in the current development of nuclear power fast reactors. Among them, the sodium-air heat exchanger damper is used to control the amount of heat exchange between sodium flow and air in the heat exchanger. It is the core component of the heat exchanger in sodium-cooled fast reactors. Its main function is to ensure that when the normal active residual heat removal loop cannot work properly due to external factors, the opening of the sodium-air heat exchanger damper can be manually controlled to ensure that the sodium-air heat exchanger works normally and safely removes the residual heat from the reactor core decay.

[0003] However, the actual operation of the air valves in sodium-air heat exchangers of sodium-cooled fast reactors involves multi-field coupling of flow field, temperature field, and solid structure field. Traditional air valves are mostly single-blade structures with poor valve body structural strength. Due to the high-temperature flow field, the valve body will experience significant deformation and stress, which may cause blade jamming and valve body strength failure, affecting its opening and closing performance and operational safety. Therefore, it is necessary to use a multi-field coupling method of fluid-thermal-solid structure to test the flow and heat transfer characteristics of the air valve, the valve body temperature distribution, valve body structural deformation, and stress according to the actual design conditions, thereby providing a reference for the design and operation characteristic research of sodium-air heat exchanger air valves. Summary of the Invention

Detailed Implementation

[0049] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please refer to this as well. Figures 1-6 The synchronous testing device for heat exchange temperature field and structural deformation disclosed in this invention is mainly used for testing air valves and simulating the thermal-fluid-structure coupling process of air valves in sodium-air heat exchangers, thereby verifying whether the air valves can work stably for a long time in sodium-cooled fast reactors. The technical solution disclosed in this invention will be described below by way of specific embodiments.

[0051] In one specific embodiment disclosed in this invention, such as Figure 1 and Figure 2The testing device mainly includes a temperature rise section 1, a test chamber 2, a temperature drop section 3, and a tracer delivery device 5. The tracer delivery device 5 contains tracer particles, which disperse within the device during operation and can also be used to recover the tracer particles. In this embodiment, the front end of the temperature rise section 1 is connected to the test chamber 2, which contains a test air valve. A laser scanner 7 is installed on the top of the test chamber 2, emitting a sheet-like laser beam that irradiates the tracer particles within the test chamber 2, causing the laser to scatter on the particles. An observation recorder is arranged outside the test chamber 2 to effectively record the scattered light from the tracer particles, preserving their trajectory by extending the exposure time. This displays the changes in thermo-fluid-structure interaction within the test chamber 2, allowing analysis of the flow field acting on the air valve. In this embodiment, the temperature rise section 1 is used to increase the temperature of the flow field within the device, which then flows through the test chamber 2, thereby simulating the actual operating conditions of the air valve. After passing through test chamber 2, the flow field enters the temperature drop section 3, which is equipped with an axial flow fan 4. The activation of the axial flow fan 4 generates a pressure difference within the device, allowing the airflow to circulate. The heat transfer fluid is located within the temperature drop section 3, and the axial flow fan 3 is immersed in it. The heat transfer fluid absorbs heat from the temperature rise section 1, increasing its temperature. Furthermore, the axial flow fan 3 can convert heat into electricity through the thermoelectric effect to drive its operation. In this embodiment, the tracer particles are micron-sized titanium dioxide particles. The first end of the tracer delivery device 5 is connected to the speed-increasing pipe 6 to improve the tracer particle recovery efficiency. Specifically, the speed-increasing pipe 6 is connected to the axial flow fan 4, and the pressure regulator 8 is connected to the temperature rise section 1. The tracer particles flow with the pressure difference generated by the axial flow fan 4, are heated in the temperature rise section 1, and then flow through the heat exchanger valve in test chamber 2. The last end of the tracer delivery device 5 is connected to the pressure regulator 8 to stabilize the airflow.

[0052] In some embodiments, the axial flow fan 4 includes a spiral fan blade 41 and a differential pressure flange sleeve 43, wherein the differential pressure flange sleeve 43 is immersed in a heat transfer fluid, and two motors 42 are installed inside the differential pressure flange sleeve 43, driving the spiral fan blade 41 to rotate. Simultaneously, a thermoelectric battery 44 is disposed outside the differential pressure flange sleeve 43, which contacts the heat transfer fluid and generates a thermoelectric electromotive force to drive the motors 42 to rotate, thereby causing the spiral fan blade 41 to rotate, resulting in airflow and tracer particles flowing within the device.

[0053] In this embodiment, the test chamber 2 includes a quartz glass tube 21, a chamber body 22, and an inner clamp 23. A pair of quartz glass tubes 21 are arranged on the front and rear sides of the chamber body 22, and an inner clamp 23 is arranged on the side of the chamber body 22. A heat exchanger damper is installed in the inner clamp 23. When the spiral fan blade 41 rotates, the airflow can pass through the temperature rise section 1 to transfer heat and tracer particles to the inner clamp 23, thereby simulating the working conditions of the heat exchanger damper in a nuclear power plant. At the bottom of the test chamber 2, a laser scanner 7 is arranged to generate sheet-like laser light that shines through the quartz glass tube 21 onto the tracer particles, and the light is scattered by the tracer particles.

[0054] Based on the previous embodiment, the laser scanner 7 includes a rotating support 71, a scanning motor 72, a laser scattering tube 73, and laser slits 74. The laser scattering tube 73 has multiple laser slits 74 on its exterior, emitting sheet-like laser beams. The laser scattering tube 73 is connected to the scanning motor 72 via a drive mechanism. The laser scattering tube 73 is rotatably mounted on the top of the rotating support 71, and is driven by the scanning motor 72 to rotate along its axis. While the laser scattering tube 73 rotates, the tracer particles in the quartz glass tube 21 can be continuously scanned through the laser slits 74 to observe the overall direction and changes in the flow field. Furthermore, the rotating support 71 is rotatably mounted on the top of the test chamber 2, thereby allowing adjustment of the horizontal angle of the laser scattering tube 73. In this embodiment, the laser scattering tube 73 is circular or square, and an encoder is installed on the scanning motor 72 to record the position and speed of the scanning motor 72 for quantitative analysis of the flow field.

[0055] In a specific embodiment of the present invention, the temperature rise section 1 includes a transformer base 11, an insulation shell 12, and a spiral heating coil 13. The insulation shell 12 is fixedly mounted on the transformer base 11, and the spiral heating coil 13 is disposed inside the insulation shell 12. The spiral heating coil 13 passes through the insulation shell 12 and is connected to the transformer base 11. The transformer base 11 supplies power to the spiral heating coil 13, and by applying a high-temperature current, the spiral heating coil 13 generates a large amount of Joule heat to simulate the thermal environment of a reactor.

[0056] In some embodiments, the voltage regulator 8 includes a compressor 81 and a voltage regulator cylinder 82 connected together, and a pressure gauge is mounted on the voltage regulator cylinder 82. The tracer delivery device 5 is connected to the temperature rise section 1 through the voltage regulator cylinder 82. The voltage regulator cylinder 82 is used to stabilize the airflow in the device, while the compressor 81 regulates the pressure inside the device by charging the voltage regulator cylinder 82.

[0057] In some embodiments, the Joule heat generated by the spiral heating coil 13 is released through the temperature drop section 3 and converted into electrical energy to drive the axial flow fan 4. The temperature drop section 3 includes a heat-conducting groove 31 and a heat exchanger 34. Specifically, the heat-conducting groove 31 is filled with heat-conducting liquid, and a displacement pump is installed on the heat-conducting groove 31 to replenish the heat-conducting liquid in real time. A first connecting joint 32 is provided at the front end of the heat-conducting groove 31, and a second connecting joint 35 is provided at the rear end of the heat-conducting groove 31. The first connecting joint 32 is sealed and connected to one end of the heat exchanger 34, the other end of the heat exchanger 34 is sealed and connected to the front end of the axial flow fan 4, and the rear end of the axial flow fan 4 is connected to the second connecting joint 35, thereby forming a closed loop in the equipment. On the other hand, the heat exchanger 34 is immersed in the heat transfer fluid, thereby storing heat in the heat transfer fluid. The heat exchanger 34 is provided with heat dissipation fins 33 on its exterior. The heat dissipation fins 33 extend into the interior of the heat exchanger 34 and are spirally arranged on the heat exchanger 34 along its length, thereby blocking the airflow and improving the heat conduction effect.

[0058] In one specific embodiment of the present invention, the tracer delivery device 5 includes a vortex tube 51, an exhaust port 53, and a three-way valve 56. The three-way valve 56 has a first port, a second port, and a third port. The third port is connected to the speed-increasing tube 6 and is adapted to communicate with one of the first and second ports. The first port is connected to the storage chamber 54, and the second port of the three-way valve 56 is connected to the vortex tube 51. The second port of the three-way valve 56 is arranged tangentially to the vortex tube 51. When the second and third ports of the three-way valve 56 are connected, airflow and tracer particles enter through the inner wall of the vortex tube 51, forming a vortex. This causes the tracer particles to fall into the storage chamber 54 along the inner wall of the vortex tube 51 under the action of centrifugal force. Clean airflow exits from the exhaust port 53 located at the top of the vortex tube 51. Correspondingly, the storage chamber 54 is connected to the bottom of the cyclone tube 51, and the bottom of the storage chamber 54 is provided with a discharge valve 55, through which the separated tracer particles or titanium dioxide powder can be discharged. In addition, a tracer inlet 52 is provided in the inclined direction of the cyclone tube 51 for introducing tracer particles of different materials for flow field analysis. When the second port and the first port of the three-way valve 56 are connected, the airflow flows out of the exhaust port 53 through the storage chamber 54, thereby driving the tracer particles to circulate within the device so that the laser scanner 7 can perform scanning observation.

[0059] Based on the same inventive concept, this invention also discloses a method for simultaneous testing of heat exchange temperature field and structural deformation, such as... Figure 7 It includes the following steps:

[0060] S1. Install the air valve into the test chamber, start the preheating of the temperature rise section, and at the same time increase the temperature of the heat transfer liquid in the temperature drop section, so that the temperature difference battery generates a voltage difference to drive the axial flow fan to run, so that the air in the device that has been dehumidified and dusted circulates.

[0061] S2. When the temperature in the temperature rise section reaches the threshold, tracer particles are introduced into the tracer delivery device, and the tracer particles pass through the test chamber under the action of the axial flow fan.

[0062] S3. Activate the laser scanner to illuminate the test chamber, causing the tracer particles to scatter, and the scattered light passes through the test chamber and enters the observation recorder;

[0063] S4. The observation recorder simultaneously records the scattered light, the trajectory and dynamic density of the tracer particles, and uses an infrared sensor to detect the intensity of infrared radiation emitted by the observed tracer particles.

[0064] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
