[0068] In one embodiment of the present invention, the hydrogen storage module reactor test platform fills the gap that the reactor 11 cannot be tested by a single device before integration, and can perform basic function tests and is easy to operate;

[0069] Among them, the power supply and electrical integrated control module 1 integrates control logic and relay protection mechanism, aiming to ensure the stability and safety of the power output of the test platform. When the reactor 11 is accurately installed and fixed on the installation and fixing platform 7, the power supply and electrical integrated control module 1 can provide stable and reliable power supply and precise electrical regulation control for the comprehensive test of the test platform, and ensure the smooth progress of the test process.

[0070] The fluid pipeline module 2 is used for raw material transportation and recovery, connecting the test platform and the reactor 11, and realizing the efficient transportation, cooling and circulation of organic liquid, temperature-controlled cooling water and key gases (nitrogen and hydrogen). The organic liquid pipeline is specially designed to efficiently realize the input and recovery functions of new organic liquid and circulating organic liquid.

At the same time, it is equipped with advanced acquisition modules, which can detect and record the temperature and pressure changes experienced by the gas at each key stage of the transmission process in real time and accurately, ensuring the safety and efficiency of the operation;

[0071] The display instrument module 3 is equipped with a series of precision instruments, which can accurately display and measure the pressure and flow of liquid and gas in the operation of the hydrogen storage module in real time, provide intuitive and reliable data support, and help accurate analysis and optimization;

[0072] The control valve module 4 integrates valve control technology, which can accurately control the input and output of organic liquid, nitrogen purge process and hydrogen input and output in the test platform, especially the flow and liquid level control of circulating hydrogen, circulating organic liquid, circulating temperature-controlled cooling water and hydrogen-containing organic liquid buffer tank to achieve highly automated and refined control of the test process. Through the collected flow, pressure and liquid level transformation, the valve opening is intelligently adjusted through data processing and calculation to achieve refined control, thereby improving test efficiency and safety;

[0073] The integrated control panel 5 is the core control center of the test platform. The control panel integrates the operating system and supports users to automatically or manually adjust various technical parameters of the test platform through an intuitive interface. At the same time, it monitors the overall safety of the platform and integrates multiple safety protection measures, such as overheat protection, overvoltage protection, leakage detection and emergency shutdown functions to ensure the safety of the test process. The integrated control panel 5 also has powerful data management capabilities and can automatically record and store key data throughout the entire experimental process, providing a solid data foundation for subsequent data analysis, report writing and system optimization.

[0074] The frame 1 6 is constructed of high-strength materials and has a stable structure. It is designed to integrate and fix the power supply and electrical integrated control modules 1, 2, 3, 4, and the integrated control panel 5.

[0075] The purpose of installing the fixed platform 7 is to securely and firmly fix the reactor 11 to be tested in the test environment. At the same time, it is also equipped with an efficient liquid leakage collection and treatment system to effectively prevent liquid leakage that may occur during the test process, ensure the cleanliness and safety of the test environment, and meet the strict requirements of modern laboratories for environmental protection and safety;

[0076] The hydrogen circulation and pressurization module 8 plays a vital role in the hydrogen storage process. Through an efficient circulation mechanism, hydrogen is continuously transmitted and pressurized in a specific closed loop to ensure that hydrogen can be supplied to the required reactor 11 at a stable pressure and flow rate. The hydrogen circulation and pressurization module 8 is composed of a circulation pump, a pressure sensor, a regulating valve and other components. The circulation pump is responsible for promoting the flow of hydrogen in the system, and the pressure sensor monitors the pressure of hydrogen in real time so that the regulating valve can accurately adjust the pressure value of hydrogen according to actual needs, improve the utilization efficiency of hydrogen, and ensure the safe and stable operation of the reactor 11, providing reliable technical support;

[0077] The reactor circulation cooling temperature control module 9 is crucial to maintaining the stable operation of the reactor 11. It is mainly composed of a built-in cooling circulation pump, a cooling medium, a temperature sensor, a controller, etc. The cooling medium is continuously pushed by the built-in cooling circulation pump, and then the cooling medium is provided to the shell side circulation of the reactor 11 through the temperature control cooling water pipeline of the fluid pipeline module 2 to take away the excess heat generated during the operation of the reactor 11. The temperature sensor in the fluid pipeline module 2 monitors the inlet and outlet temperature changes of the reactor 11 in real time, and transmits the data to the PLC. After data processing, the PLC sends instructions to the controller to accurately adjust the flow rate of the cooling circulation pump and the flow rate of the cooling medium and other parameters according to the preset temperature range to ensure that the reactor 11 is always within the appropriate temperature range. The reactor circulation cooling temperature control module 9 can effectively prevent the reactor 11 from being damaged due to excessive temperature, extend the service life of the reactor 11, ensure the efficient and safe progress of the reaction process, and provide reliable temperature control guarantee for various test items;

At the same time, the frame 2 10 also has excellent thermal isolation performance, reducing the interference of heat transfer between different modules, ensuring the high efficiency of hydrogen circulation boosting and the accuracy of reactor cooling temperature control, and providing solid support for the smooth progress of the entire process;

[0079] Among them, the power supply and electrical integrated control module 1 is equipped with an explosion-proof electrical control box system, such as Figure 3 As shown in the figure, the system cleverly divides the internal space into two completely isolated and functionally specific areas: the weak current area (control cabin) and the strong current area (wiring cabin), which not only ensures the safety of the operating environment, but also greatly improves the stability and reliability of the system operation. The weak current area (control cabin) is the nerve center of the system, mainly responsible for precise signal processing and data transmission tasks. It integrates an advanced system control unit (PLC) to achieve automatic control and remote monitoring; it is equipped with an efficient data acquisition module that can collect equipment operating parameters in real time and accurately; at the same time, a stable equipment communication network is built to ensure unimpeded information exchange between components. The design of this area fully considers electromagnetic compatibility. Capacitance effectively avoids the influence of external interference on weak current signals, and ensures the accuracy and security of data transmission; the strong current area (wiring compartment) is the power source and undertakes the important task of providing stable and reliable power supply for all strong current equipment in the test platform. It is equipped with a high-performance power distribution system, which can flexibly adjust the output voltage and current to meet the power requirements of different equipment. In addition, the area also integrates power collection devices, which can monitor power consumption in real time and provide data support for energy management. More importantly, the strong current area also incorporates advanced relay protection technology, which can quickly cut off the power supply when abnormal conditions are detected, effectively preventing the occurrence of safety accidents such as electrical fires, and escorting the safe operation of the system;

[0080] The control principle of the power supply and electrical integrated control module 1 of the test platform is as follows Figure 4 As shown, the description is as follows:

[0081] In the power supply and electrical integrated control module 1, the manual operation mode is realized through an advanced user interface (host computer operation interface), which allows the operator to directly send instructions to the programmable logic controller (PLC), which then interprets these instructions and sends control signals to the frequency converter or contactor in the electrical control box to accurately adjust the power or start and stop status of the liquid inlet pump, hydrogen booster, circulating cooler, etc., the opening of the pneumatic and electric regulating valves, and the start and stop and heating temperature of the start preheater;

[0082] In the automatic control mode, the system first presets key process parameters in the host computer, including but not limited to setting the start and stop temperature of the preheater, the temperature control range of the circulating cooler, the circulating hydrogen flow rate, the circulating organic liquid flow rate, the liquid level range of the hydrogen-containing organic liquid buffer tank, the system pressure range, etc. Then, the acquisition module composed of temperature, flow and pressure sensors monitors and feeds back the system status information in real time. Once the system status reaches the preset automatic adjustment condition, the PLC will automatically intervene and send precise control instructions to the frequency converter or contactor in the electrical control box according to the feedback data to dynamically adjust the power of the liquid inlet pump, the temperature difference and flow rate of the circulating cooler, the opening and closing degree of the circulating organic liquid and circulating hydrogen flow regulating valves, and the opening and closing of the hydrogen booster and the hydrogen-containing organic liquid buffer tank discharge regulating valve, so as to realize closed-loop automatic control;

[0083] After the test cycle is over, the operator can set the corresponding data processing parameters through the host computer, and the system will automatically summarize and analyze the data collected during this test cycle. Through comparative analysis, the system can generate a detailed test report, providing a scientific basis for subsequent process optimization, equipment maintenance or troubleshooting. This process not only improves the test efficiency and accuracy, but also ensures the intelligence and efficiency of the control system.

[0084] The test platform can perform the following related tests on hydrogen storage reactions with organic liquid hydrogen storage efficiency of 0-6.5kg / h and liquid inlet and outlet flow of 0-100kg / h:

[0092] Reactor inlet and outlet temperature test: During the hydrogen storage process, monitor and record the reactor inlet and outlet temperature data, which helps to understand the heat exchange efficiency and temperature distribution inside the reactor and ensure that the reactor has good performance in temperature control.

[0093] Maximum flow rate test of the reactor: Test the maximum flow rate that the reactor can withstand under specific conditions to evaluate the processing capacity of the reactor. By gradually increasing the flow rate, observe the performance changes and stability of the reactor, find its maximum processing capacity, and ensure that this limit will not be exceeded in actual applications to ensure the normal operation and life of the equipment;

[0094] Corrosion resistance test: Since different chemicals may be involved in the hydrogen storage process, the reactor needs to have good corrosion resistance. The corrosion resistance of the reactor is evaluated by placing it in a simulated corrosion environment and observing its corrosion over a certain period of time.

[0095] Seismic performance test: In actual applications, the equipment may be affected by vibration. The reactor is tested for seismic performance to simulate vibration conditions of different intensities and check the structural integrity and performance stability of the reactor.

[0099] Comprehensive performance evaluation of the equipment: After completing the above tests, the comprehensive performance of the equipment is evaluated through the built-in system program to confirm whether the equipment meets the design requirements and technical specifications.

[0100] like Figure 5 FIG. 1 is a schematic diagram of an operation method of a hydrogen storage module reactor test platform provided by an embodiment of the present invention, comprising the following steps:

[0101] S1. The reactor 11 is fixed on the installation and fixing platform 7, and the inlet and outlet water, gas and liquid circuits of the test platform are connected to build a simple test stand to meet the normal inlet and outlet, exhaust, circulating cooling water temperature flow control and other functions of the reactor 11;

[0102] S2. The operator powers on and starts the test platform to observe whether the temperature, pressure, inlet and outlet flow and other communication equipment between the control communication unit, reactor 11 and the platform are normal;

[0103] S3. During the test, the integrated control panel 5, circulating cooling thermostat, reactor start-up preheater, control valve module 4, and display instrument module 3 are used to control and monitor whether the communication of each electrical equipment is normal, and the data such as pressure, temperature, gas and liquid flow of the fluid pipeline system meet the test conditions. DBT (organic liquid) is smoothly transported from a special liquid storage tank to the test platform by starting the liquid inlet pump. At the same time, in order to ensure the smooth progress of the experimental process, the hydrogen valve is accurately opened to introduce fresh hydrogen into the system. The hydrogen and organic liquid temperature, pipeline pressure, flow and other data in the liquid inlet stage are collected through the fluid pipeline module 2, and the hydrogen is pressurized to the set value through the built-in hydrogen booster and start-up preheater. The pressure and DBT (organic liquid) are heated to the set temperature. The pressurized hydrogen and the heated organic liquid are collected into the mixer built into the test platform through the fluid pipeline module 2 for mixing. The organic liquid supply port is connected to the liquid inlet and purge inlet of the reactor 11 to enter the reactor 11 for catalytic reaction with the catalyst for hydrogen storage. DBT (organic liquid) and hydrogen are catalytically reacted in the reactor to synthesize H-DBT (hydrogen-containing organic liquid). According to the limitations of the current hydrogen storage process, the hydrogen storage capacity of the primary reactor does not meet the design requirements. Through the circulating hydrogen storage system, which includes a circulating organic liquid system and a circulating hydrogen system; unsaturated DBT (organic liquid) and surplus hydrogen are connected through pipelines through their respective return liquid ports and circulating hydrogen ports. Return to the fluid pipeline module 2 and go back to the new organic liquid pipeline and the new hydrogen pipeline to converge into the built-in mixer for circulating hydrogen storage. The fluid pipeline module 2 collects the temperature, pipeline pressure, flow rate and other data of the liquid gas in the circulating hydrogen storage stage; because the hydrogen storage reaction is an exothermic reaction and will continuously release a large amount of heat, it is necessary to start the preheater in the startup stage to heat the organic liquid to the set reaction temperature. When the reactor 11 reaches the reaction temperature and stabilizes for a period of time, the preheater can be started and shut down manually, or the automatic shutdown temperature can be set to achieve automatic shutdown; during the test, pressure safety is achieved through the pressure monitoring of the platform, and the drain valve is automatically opened when the system pressure exceeds the set value; the temperature control of the reactor 11 requires the test platform The circulating cooling thermostat automatically adjusts the inlet and outlet temperature difference and flow rate of the circulating cooling thermostat through the temperature collected by the fluid pipeline module 2, and removes excess heat from the shell side of the reactor 11, thereby controlling the temperature; DBT that has been stored in hydrogen for multiple cycles becomes high-purity H-DBT and is stored in the hydrogen-containing organic liquid hydrogen storage tank built into the test platform; the drain valve is automatically opened and closed according to the hydrogen-containing organic liquid level set by the user interface; H-DBT (hydrogen-containing organic liquid) returns to the fluid pipeline module 2 through the liquid supply return port, and the pressure, temperature, gas and liquid flow rate and other data of the H-DBT (hydrogen-containing organic liquid) fluid pipeline system at the hydrogen storage completion stage are collected, and the H-DBT (hydrogen-containing organic liquid) is connected to the liquid storage tank from the drain port for recovery;During the test, the integrated control panel 5, adjusting the liquid inlet amount, circulating hydrogen valve, circulating organic liquid valve and circulating cooling thermostat inlet and outlet temperature difference and flow rate, and controlling the valve module 4 can manually and automatically adjust the opening of the flow valves of the liquid inlet and outlet and the circulating hydrogen and organic liquid to test the data under different working conditions;

[0104] S4. After the test, cut off the new DBT liquid inlet and the new hydrogen inlet. When the temperature drops below the reaction temperature, the operator can manually increase the circulating cooling thermostat flow and open the system pressure drain valve. When the system temperature drops ≤50℃ and the system pressure ≤0.05MPa, the hydrogen storage equipment reactor test platform can be closed.
