Description

Technical Field

[0001] The present invention belongs to, but is not limited to, the technical field of temperature monitoring experiments, and particularly relates to an efficient heating and temperature monitoring experimental system applicable to multiple scenarios. Background Art

[0002] Core melting is a complex system process, and a large number of experimental studies have been conducted internationally to simulate the melting process. In a core melting accident, as decay heat continues to be generated, some core materials begin to melt to form a molten pool. During the development of the molten pool, it is surrounded by high-temperature steam or cooling debris, and a relatively thick solidified shell will form outside the molten pool to keep the molten pool in its original state. Under the action of its own gravity, the high-temperature molten pool solidified shell will squeeze and melt with the reactor internals (such as support plates, fuel elements, etc.). This kind of melting is a typical contact melting process, and the existing melting models cannot well simulate this process. Currently, most contact melting experimental platforms focus on the energy storage field for the contact melting problem in the heating container. Due to different heating methods and melting processes, the contact melting experiments in the energy storage field have little reference value for the research on the contact melting phenomenon that occurs during the severe accident process of the reactor. Currently, among the experimental devices for severe accidents of reactor core melting, there are mainly fuel rod bundle melting experimental platforms, but they cannot well experimentally simulate the contact melting process. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the present invention provides an efficient heating and temperature monitoring experimental system applicable to multiple scenarios.

[0004] The present invention is implemented as follows. An efficient heating and temperature monitoring experimental system applicable to multiple scenarios, the system includes:

[0005] A visualization experimental box for conducting visualization experiments;

[0006] A power regulation and monitoring module configured with a non-contact solid-state relay SSR to achieve constant temperature regulation and power protection; the power regulation accuracy is 0.1 W, and the real-time output power is displayed through a touch screen;

[0007] An exhaust and safety module configured with a one-way intake valve and an automatic pressure relief and exhaust valve to ensure that the gas pressure inside the box is always within a safe range; a temperature warning light is set on the top of the box, and when the outer surface temperature exceeds the set value, it will automatically light up and power off.

[0008] Furthermore, the maximum external dimensions of the visualization experimental box are: 104 cm × 83 cm × 200 cm; the internal cavity dimensions are: 60 cm × 60 cm × 70 cm.

[0009] Further, 2 windows are added to the front, back, left, and right of the visualization experiment box body, with a window diameter of 300 mm. Each side of the window uses 2 high-temperature resistant glasses, and both sides are fixed in a flange type to enhance its sealing and heat insulation performance.

[0010] Further, the glass used for the sealing of the visualization experiment box body is installed and sealed in the standard form of a flange, and the flange seal adopts national standards;

[0011] The sealing of the wire passing hole of the box body mainly adopts the form of high-temperature resistant sealant. Since the inside of the box body bears high pressure, the solidification and sealing characteristics of the colloid are sufficient to seal the wire passing hole, so that the gas inside the box cannot be discharged from the wire passing hole, achieving the sealing effect of the box body;

[0012] The sealing at the door seam of the box body is installed with an M-shaped high-temperature resistant sealing strip at the door seam, and the door seam is sealed by relying on the extrusion deformation when closing the door. It can withstand high temperatures without deformation. The periphery of the door frame and the inner liner of the door edge adopt a double-layer sealing form to enhance the sealing effect.

[0013] Further, the power regulation and monitoring module uses 220V, 50HZ AC incoming line, with a total power of 3KW; it is divided into 48 K-type contact thermocouple temperature sensors according to the hardware layout position, and 1 is arranged in the control box connected to the lower part of the temperature experiment box; the K-type contact thermocouple temperature sensor measures and collects the positions of the heater and the heated parts; the data acquisition module of the temperature inspection instrument in the control box receives the sensor data and displays the real-time data; the PLC end control software processes and displays the thermocouple temperature data on the heater in real time, so as to complete functions such as data acquisition and maintenance of the target temperature; the PC can communicate with the inspection instrument and the PLC control system by wire, and the communication distance is greater than 10 meters.

[0014] Further, the specific implementation plan of the power regulation and monitoring module is as follows:

[0015] (1) Automatic constant temperature: The temperature controller can automatically calculate and output the power according to the temperature value set by the user. When it is closer to the temperature set value, the output power is smaller, so as to achieve the purpose of constant temperature control and save energy and electricity;

[0016] (2) Over-temperature protection temperature controller: The PID microcomputer intelligent built-in temperature controller automatically adjusts and calculates the output, with precise control. When the temperature exceeds the set value of the over-temperature protection temperature controller, the heating power supply is automatically cut off;

[0017] (3) Heating tube control: Each heating tube adopts a non-contact SSR (solid state relay);

[0018] (4) The power adjustment range of the power supply is 0 - 3KW; the programming resolution of the power supply is 0.1W; the display resolution is 1W; users can program the output voltage and current of the power supply through the analog quantity of the REMOTE interface (DB26) on the rear panel of the power supply. At the same time, the REMOTE interface (DB26) on the rear panel also provides monitoring signals for the output voltage and current of the user; the ranges of the programming signal and the monitoring signal can be set to 0 - 5V or 0 - 10V through local control or remote communication;

[0019] (5) The analog output module of the PLC is connected to the REMOTE interface, and the output power of the power supply is controlled by controlling the change of voltage or current through the output analog quantity. The change curve of the analog quantity is the change curve of the power. Through the buttons on the HMI, the changed power and the time of power change are input; at the same time, the power and time can be displayed on the HMI for monitoring, and the power can be adjusted in gears and steplessly; the two adjustment methods can be connected in series for application;

[0020] (6) The output power is adjustable, and the adjustment formula is shown in the formula P(t) = P0 + k * t; P(t) is the output power, P0 is the initial power, k is the slope value, and t is the time. The P(t) power output value changing with time can be obtained.

[0021] Furthermore, the control method and characteristics of the power adjustment and monitoring module are as follows:

[0022] (1) Adopt a 5-inch touch screen programmable PLC controller;

[0023] (2) Can record temperature data in real time, store up to 1000 days of data, support U disk to export documents, and can be directly opened on the computer side;

[0024] (3) The controller intelligently controls the temperature change data, dynamically adjusts the output power for energy saving, and ensures stable temperature and energy saving;

[0025] (4) 99 temperature operation programs can be edited and set, and each program can run at 99 different temperatures and times;

[0026] (5) Control with a middle relay;

[0027] (6) The heating method set by the power curve is switched through a conversion knob, and it is switched to the adjustable power supply for self-heating, and the power can be automatically decreased according to a certain slope.

[0028] Furthermore, the exhaust and safety module is provided with an air inlet and an air outlet. The intake valve and the exhaust valve are both one-way valves. Gas is filled from the air inlet. When the pressure in the box is once higher than the set differential valve threshold, it will automatically relieve pressure through the exhaust valve. Therefore, too much high-pressure gas will not accumulate in the box.

[0029] Furthermore, the exhaust and safety module is designed with a high-temperature warning control switch. When the temperature outside the box exceeds the set temperature, the red warning light on the upper part of the box will light up, preventing people from being scalded by high temperature when touching the outer wall or handle of the box. A local temperature display instrument is also equipped on the upper part of the box, and the temperature indicated by the thermometer can be observed in real time when opening the door or operating, so as to avoid scalding.

[0030] Another object of the present invention is to provide an information data processing terminal, which is used to implement the multi-scenario applicable high-efficiency heating and temperature monitoring experimental system.

[0031] Combined with the above technical solutions and the solved technical problems, the advantages and positive effects of the technical solution to be protected by the present invention are as follows:

[0032] First, the experimental equipment in the prior art generally has problems such as low heating control accuracy and large temperature fluctuations, making it difficult to meet the requirements of high-precision experiments. The present invention realizes high-precision power adjustment by introducing a non-contact solid-state relay (SSR), with a power adjustment accuracy of up to 0.1W, capable of dynamically adjusting the heating power to ensure the temperature stability inside the experimental box. The temperature monitoring module combined with the real-time feedback mechanism can not only accurately monitor the temperature of the experimental environment, but also automatically cut off the power when the limit is exceeded through the warning light and alarm, greatly improving the safety and reliability of the experiment.

[0033] In many experimental scenarios, the gas pressure and circulation management inside the experimental box directly affect the accuracy and safety of the experimental results. Existing equipment usually lacks effective pressure control devices, easily leading to uneven gas or excessive pressure inside the experimental box. The present invention realizes the efficient circulation and stable pressure control of the gas inside the experimental box by configuring a one-way intake valve and an automatic pressure relief exhaust valve, combined with the guide tube design. This technology not only solves the problem of uneven gas distribution in the experimental environment, but also improves the repeatability and safety of the experiment, and is especially suitable for closed heating and high-temperature experimental scenarios.

[0034] Existing experimental equipment often performs poorly in terms of operation convenience and adapting to different experimental requirements, resulting in low efficiency. The present invention improves the operation convenience by integrating an observation side window, a movable door design, and modular power boxes and power cabinets, supporting rapid sample replacement and maintenance. At the same time, the system supports flexible setting and real-time adjustment of different experimental parameters, enabling it to be widely applicable to various scenarios, including high-precision material experiments, chemical reaction research, and gas dynamic monitoring, etc. Its remarkable technological progress lies in improving the experimental efficiency, data reliability, and flexibility of equipment operation, providing strong support for the scientific research and industrial fields.

[0035] Combined with the adjustable power output and the intelligent temperature control module, it realizes precise control from rapid heating to constant temperature maintenance.

[0036] The multi-window design facilitates experimental observation and high-speed camera recording.

[0037] It is applicable to a variety of experimental scenarios, including high-temperature environmental material testing, reactor accident analysis, etc.

[0038] Performance advantages:

[0039] High control precision: The temperature fluctuation range ≤ ±0.5°C.

[0040] It provides efficient data recording and export functions, and supports USB export of experimental results.

[0041] The present invention analyzes the contact melting effect of different-shaped heating components on the melting test piece by simulating different power levels and decay heat conditions.

[0042] Second, the expected benefits and commercial value after the transformation of the technical solution of the present invention are:

[0043] After the transformation of the technical solution of the present invention, it can be used for experimental research on the reactor melting process and contact melting experiments. It can simulate the contact melting process of various heating methods and heating parts with various shapes. The experiments conducted can further analyze and study the relevant mechanisms of contact melting.

[0044] The technical solution of the present invention fills the technical gaps in the industry at home and abroad:

[0045] At present, most of the heating melting experiments for severe reactor accidents at home and abroad are fixed constant-power heating. This technology can, through self-programming, achieve multiple heating methods such as constant temperature, constant power, and linear power. The heating component will migrate downward as the material melts, which can well reflect the complex heating process of reactor core melting. In addition, it can also be used for experimental research on the relevant mechanisms of contact melting. Description of the Drawings

Detailed implementation manners

[0057] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0058] As shown in Figure 1 、 2 、5, the embodiment of the present invention provides an efficient heating and temperature monitoring experimental system applicable to multiple scenarios. The system includes:

[0059] Pressure gauge 1, thermometer 2, over-limit alarm 3, experimental bench 4, movable side door 5, observation movable door 6, power supply box 7, observation side window 8, air inlet 9, experimental box 10, exhaust hole 11, guide pipe 12, power supply cabinet 13.

[0060] A visual experimental box 10 for conducting visual experiments;

[0061] A power adjustment and monitoring module, configured with a non-contact solid-state relay SSR to achieve constant temperature adjustment and power protection; the power adjustment accuracy is 0.1W, and the real-time output power is displayed through a touch screen;

[0062] An exhaust and safety module, configured with a one-way intake valve and an automatic pressure relief exhaust valve to ensure that the gas pressure inside the box is always within a safe range; a temperature warning light is set on the top of the box, which automatically lights up and cuts off the power when the outer surface temperature exceeds the set value.

[0063] The experimental system of the present invention realizes efficient heating and constant temperature control through the power regulation and monitoring module. The heating device inside the experimental chamber 10 is controlled by a non-contact solid-state relay (SSR), and its power regulation accuracy is as high as 0.1W. The user sets the required heating power through the touch screen and the output power is displayed in real time to ensure the accuracy of the experimental conditions. The SSR can dynamically adjust the heating power according to the real-time temperature feedback signal, avoid excessive temperature fluctuations, and monitor the power output at the same time to prevent overload or abnormal conditions.

[0064] The experimental chamber 10 is equipped with a multi-layer temperature monitoring device, and the internal and outer surface temperatures of the chamber are monitored in real time through the built-in thermometer 2. When the outer surface temperature exceeds the set safety value, the temperature warning light on the top of the chamber will automatically turn on, and at the same time, the overlimit alarm 3 will be triggered to remind the operator to deal with it immediately. At the same time, the system interrupts the power supply of the heating device through the power-off protection function to further ensure the safety of the equipment and experimental personnel.

[0065] The system designs an efficient gas circulation and pressure relief scheme. The experimental chamber 10 is provided with an exhaust hole 11 at the top and an air inlet hole 9 at the bottom, which are connected to a one-way air inlet valve and an automatic pressure relief and exhaust valve. When the gas pressure inside the chamber rises during the experiment, the automatic pressure relief and exhaust valve will discharge the excess gas in time to ensure that the internal pressure is always within the safe range. The guide pipe 12 is connected to the experimental chamber to guide the gas to circulate evenly inside, avoiding problems such as local high pressure or uneven temperature, and improving the experimental accuracy and safety.

[0066] The experimental system is convenient for real-time monitoring of the experimental process through the observation side window 8 and the observation activity door 6. The movable side door 5 is designed to facilitate the operator to replace samples or maintain equipment. The power supply box 7 and the power cabinet 13 are independently configured to avoid electrical interference during the experiment. After the heating or experiment is completed, the cooling mode can be manually or automatically started through the touch screen, and combined with the exhaust hole 11 to quickly cool down, preparing for the next experiment. In addition, the box body material has been specially treated, with good high-temperature resistance and insulation effects, providing a reliable safety guarantee for multi-scenario experiments.

[0067] The exhaust and safety module is designed with a high-temperature and high-pressure warning control system. When the external temperature of the chamber is too high and exceeds the set temperature, the overlimit alarm 3 on the upper part of the chamber will light up; to prevent the human body from being scalded by high temperature when touching the outer wall or handle of the chamber; the upper part of the chamber is also equipped with a local temperature display instrument, and the temperature indicated by the thermometer 2 can be observed in real time when opening the door or operating to avoid scalding.

[0068] The maximum overall dimensions of the visual experimental chamber 10 are: 104 cm × 83 cm × 200 cm; the internal cavity dimensions are: 60 cm × 60 cm × 70 cm. A double-door structure with different sizes is provided at the front of the chamber. The large door is used for replacement after experimental melting, and the small door is used to be opened during the experiment, which can not only not affect the infrared camera shooting but also prevent the heat dissipation inside the chamber as soon as possible.

[0069] As Figure 2 shown, two windows are added to the left and right of the visual experimental chamber 10. The window diameter is: 300 mm. Each side of the window uses two pieces of high-temperature resistant glass, and both sides are fixed in a flange form to enhance its sealing and heat insulation performance.

[0070] The glass used for the seal of the visual experimental chamber 10 is installed and sealed in the standard form of a flange, and the flange seal adopts the national standard;

[0071] The seal of the wire passing hole of the chamber mainly adopts the form of high-temperature resistant sealant for sealing. Because the inside of the chamber bears high pressure, the solidification and sealing characteristics of the colloid are sufficient to seal the wire passing hole, so that the gas inside the chamber cannot be discharged from the wire passing hole, achieving the sealing effect of the chamber;

[0072] The seal at the door gap of the chamber is installed with an M-shaped high-temperature resistant sealing strip at the door gap. The door gap is sealed by relying on the extrusion deformation when the door is closed. It can withstand high temperatures without deformation. The periphery of the door frame and the inner liner of the door edge adopt a double-layer sealing form to strengthen the sealing effect.

[0073] The visual experimental chamber 10 is the core component of the system, supporting multi-scenario experiments with efficient heating and temperature monitoring.

[0074] The overall dimensions of the chamber are 104×83×200 cm, and the internal cavity dimensions are 60×60×70 cm, providing a suitable sealed space for the experiment.

[0075] Windows with a diameter of 300 mm are added to the front, back, left, and right. Double-layer high-temperature resistant glass is used and fixed in a flange form to enhance the sealing and heat insulation performance, and at the same time, the experimental process can be visually observed.

[0076] To ensure the safety and precision of the experimental environment, the chamber adopts a multi-layer sealing design:

[0077] Flange seal: The double-layer glass of the window is fixed in the standard form of a flange to ensure airtightness and pressure resistance, meeting the national standard.

[0078] Seal of wire passing hole: The wire passing hole is sealed with high-temperature resistant sealant, and its solidification characteristics are used to resist high pressure and prevent gas leakage inside the chamber.

[0079] Seal of door gap: Install an M-shaped high-temperature resistant sealing strip at the door gap of the chamber. A tight seal is formed through the extrusion deformation of the door to further strengthen the airtight effect of the chamber.

[0080] This module realizes constant temperature regulation and power protection by configuring a contactless solid-state relay (SSR):

[0081] The power regulation accuracy reaches 0.1W, ensuring precise control during the heating process.

[0082] The real-time output power is displayed on the touch screen, facilitating users to monitor the experimental process.

[0083] In high-temperature experimental scenarios, the contactless feature of the SSR avoids the arc risk of traditional relays, improving the reliability and safety of the system.

[0084] To control the gas pressure and temperature inside the chamber, this module provides the following functions:

[0085] Configure a one-way intake valve and an automatic pressure relief exhaust valve to ensure that the gas pressure inside the chamber is always within a safe range.

[0086] When the temperature of the outer surface of the chamber exceeds the set value, the top temperature warning light automatically lights up, and at the same time, the power supply is cut off to protect the safety of the equipment and operators.

[0087] The chamber provides excellent heat insulation performance through double-layer glass and flange fixing methods.

[0088] Adopt high-temperature-resistant materials and a double-sealed door frame design to ensure the internal stability of the chamber under high-temperature and high-pressure conditions.

[0089] The design of each sealing component has been optimized to resist thermal deformation and chemical corrosion in the long-term experimental environment.

[0090] The system is applicable to a variety of experimental scenarios, including chemical reactions, high-temperature material testing, pressure vessel experiments, etc.

[0091] Flexibly adjust the heating power and temperature to meet different experimental requirements.

[0092] The visualization window and real-time monitoring module provide clear experimental feedback, improving the experimental efficiency and accuracy.

[0093] The versatility and high safety of this system make it an ideal choice in scientific research and industrial applications.

[0094] Such as Figure 3 、 4As shown in the figure, the power regulation and monitoring module uses a 220V, 50HZ AC input line, with a total power of 3KW. It is divided into 48 K-type contact thermocouple temperature sensors according to the hardware layout position, and 1 is arranged in the control box connected to the lower part of the temperature test chamber. The K-type contact thermocouple temperature sensors measure and collect the positions of the heater and the heated parts. The data acquisition module of the temperature inspection instrument in the control box receives the sensor data for real-time data display. The PLC-side control software processes and displays the thermocouple temperature data on the heater in real time, thus completing functions such as data acquisition and maintenance of the target temperature. The PC can communicate with the inspection instrument and the PLC control system by wire, and the communication distance is greater than 10 meters.

[0095] The specific implementation plan of the power regulation and monitoring module is as follows:

[0096] (1) Automatic constant temperature: The temperature controller can automatically calculate and output the power according to the temperature value set by the user. When it is closer to the temperature set value, the output power is smaller, so as to achieve the purpose of constant temperature control and save energy and electricity.

[0097] (2) Over-temperature protection temperature controller: The PID microcomputer intelligent built-in temperature controller automatically adjusts and calculates the output, with precise control. When the temperature exceeds the set value of the over-temperature protection temperature controller, the heating power supply is automatically cut off.

[0098] (3) Heating tube control: Each heating tube adopts a non-contact SSR (solid state relay).

[0099] (4) The power adjustment range of the power supply is 0 - 3KW; the programming resolution of the power supply is 0.1W; the display resolution is 1W. Users can program the output voltage and current of the power supply through the REMOTE interface (DB26) analog quantity on the rear panel of the power supply. At the same time, the REMOTE interface (DB26) on the rear panel also provides monitoring signals for the output voltage and current for users. The ranges of the programming signal and the monitoring signal can be set to 0 - 5V or 0 - 10V through local control or remote communication.

[0100] (5) The analog output module of the PLC is connected to the REMOTE interface. By outputting analog quantities to control the changes in voltage or current, the output power of the power supply is controlled. The change curve of the analog quantity is the change curve of the power. Through the buttons on the HMI, the changed power and the time of power change are input. At the same time, the power and time can be displayed on the HMI for monitoring, and the power can be adjusted in gears and steplessly. The two adjustment methods can be connected in series for application.

[0101] (6) The output power can be adjusted, and the adjustment formula is shown in the formula P(t) = P0 + k * t; P(t) is the output power, P0 is the initial power, k is the slope value, and t is the time. The P(t) power output value changing with time can be obtained.

[0102] The control methods and characteristics of the power regulation and monitoring module are as follows:

[0103] (1) Adopt a 5-inch touch screen programmable PLC controller;

[0104] (2) Can record temperature data in real time, store up to 1000 days of data, support U disk export of documents, and can be directly opened on the computer side;

[0105] (3) The controller's AI intelligent control temperature change data, energy-saving dynamic adjustment of output power to ensure stable and energy-saving temperature;

[0106] (4) Can edit and set 99 temperature operation programs, and each program can run 99 segments of different temperatures and times;

[0107] (5) Control with an intermediate relay;

[0108] (6) The heating method set by the power curve is through the switching of the conversion knob, switching to an adjustable power supply for self-heating, and the power can be automatically decreased according to a certain slope.

[0109] As Figure 5 shown, the exhaust and safety module is provided with an air inlet and an air outlet. Both the air inlet valve and the air outlet valve are one-way valves. The inert gas filled in the experiment is helium. Therefore, the air inlet valve is arranged above the box body, and the air outlet valve is arranged on the lower side of the box body. When inflating, the helium gas is used to discharge the air downward by gravity. To avoid the damage of the high-temperature gas discharged directly downward during heating to the high-temperature power supply, a guide pipe 12 is connected to the air outlet valve to discharge the high-temperature gas from the side. When the pressure in the box body is once higher than the set differential pressure threshold, it will automatically relieve pressure through the air outlet valve, so that too much high-pressure gas will not accumulate in the box body.

[0110] As Figure 6 shown is the layout schematic diagram of the melting part 16 and the heating part 15 in the experiment. The melting part is fixed in the workbench 18 through a plug, and the temperature measuring thermocouple 16 is inserted according to the experimental needs. A through hole is opened in the middle of the heating part 15, and a guide rod 14 is inserted along the hole. The guide rod 14 is installed and fixed to the workbench through a plug. The insertion of the guide rod can ensure the vertical melting movement of the heating part, prevent the heating part from slipping during the melting process, and enhance the stability of the experiment.

[0111] The embodiment of the present invention provides an information data processing terminal, and the information data processing terminal is used to implement the multi-scenario applicable high-efficiency heating and temperature monitoring experimental system.

[0112] As Figure 7 、 8 shown, it is the actual experimental process provided by the embodiment of the present invention, which can better complete the relevant melting process and record temperature data.

[0113] The temperature control box can select the constant temperature value and the heating power during constant temperature heating through the control panel, and set the alarm temperature and pressure in the alarm interface. When the temperature and pressure exceed the preset values, the alarm on the upper part of the box will sound. During the experiment, the temperature values of 48 thermocouples can be observed in real time through the control panel of the box. After the experiment, the operation data can be exported to a USB flash drive for processing. The resulting effect diagram of the temperature change over time is as follows. According to the temperature values of each cross-section, the change of the average heat flux density of each plane over time can be obtained using Fourier's law of heat conduction, as follows Figure 9 、 10 shown. This experimental bench can better reflect the influence of the migration and solidification of the melt on the melting process during contact melting.

[0114] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention shall be covered by the protection scope of the present invention.
