Description

Technical Field

[0001] The invention relates to the technical field of hydrogen storage, and in particular to a hydrogen storage system with a monitoring function. Background Art

[0002] As the global demand for clean energy continues to increase, hydrogen energy has attracted more and more attention due to its high energy density and clean combustion products. In order to promote the use of hydrogen energy in transportation, industrial production and energy storage, the industry continues to develop various hydrogen storage technologies and supporting safety protection and monitoring methods.

[0003] At present, most common hydrogen storage systems adopt simple gas cylinders or storage tanks, and are equipped with corresponding valves and monitoring instruments on the outside to maintain the appropriate hydrogen storage temperature and pressure to a certain extent. At the same time, some systems have also begun to try to use inert gases such as argon to form a low-oxygen or inert environment to reduce the risk of combustion and explosion, and to monitor the safety of hydrogen storage systems.

[0004] With regard to the existing technology, traditional hydrogen storage devices often find it difficult to balance temperature uniformity, hydrogen purity management and safety protection when facing various extreme or complex working conditions such as high temperature, low temperature, and cyclic pressurization. On the one hand, if the bottom or the sides cannot be fully and evenly heated or cooled, it is easy to cause the temperature in the local area to be too high or too low, thereby causing material stress concentration or low hydrogen storage efficiency. On the other hand, the existing technology is still insufficient in the recovery of inert gases and the purification of hydrogen. In addition, most traditional systems are relatively simple in protecting against backflow shock and explosion hazards, lack recoil anti-backflow components, and integrated solid-state hydrogen storage buffer solutions. Therefore, those skilled in the art provide a hydrogen storage system with a monitoring function to solve the problems raised in the above background. Summary of the invention

[0005] The purpose of the present invention is to provide a hydrogen storage system with a monitoring function to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The hydrogen storage system includes a hydrogen storage tank, a mounting frame, a temperature control mechanism, a control mechanism, a protection mechanism and a detection mechanism. The protection mechanism, the hydrogen storage tank and the temperature control mechanism are all tightly connected to the mounting frame. The hydrogen storage tank is placed vertically, the temperature control mechanism and the hydrogen storage tank are tightly connected, the control mechanism and the hydrogen storage tank are tightly connected, and the detection mechanism and the hydrogen storage tank are tightly connected.

[0008] By adopting the above technical solution, the hydrogen storage tank is used to contain and store hydrogen; its vertical placement can better utilize space and facilitate the stratification and flow control of internal hydrogen. The mounting frame plays a role in firmly supporting the hydrogen storage tank, temperature control mechanism, and protection mechanism to ensure the stability of the system. After the temperature control mechanism is tightly connected to the hydrogen storage tank, the internal temperature of the hydrogen storage tank can be accurately adjusted. The control mechanism is used to control the inlet and outlet of hydrogen and flow regulation, and is tightly connected to the hydrogen storage tank to prevent vibration or leakage. After the protection mechanism is tightly connected to the mounting frame, safety measures can be implemented in abnormal situations. The detection mechanism monitors the system status in real time, and the tight connection with the hydrogen storage tank helps to accurately obtain key parameters such as temperature, pressure, and concentration, realizing the stability and functional complementarity of the hydrogen storage system, and improving safety and operability.

[0009] Furthermore, the hydrogen storage tank includes a tank body, an air inlet pipe and an air outlet pipe, the air inlet pipe is connected to the tank body, the air outlet pipe is connected to the tank body, and the air inlet pipe and the air outlet pipe are both located at the upper end of the tank body.

[0010] By adopting the above technical solution, the tank body is the core container of the entire hydrogen storage system, which is used to store hydrogen or its mixed gas. Placing both the inlet pipe and the outlet pipe at the upper end of the tank body can simplify the pipeline layout and reduce the space occupied by the bottom pipeline. After the hydrogen enters from the inlet pipe, it is stored in the tank body. When hydrogen needs to be discharged or transported, it is exported through the outlet pipe, which is convenient for centralized management and control. Since the inlet and outlet are adjacent and located at the upper end, it is conducive to improving the efficiency of hydrogen use and reducing the safety hazards caused by low-level pipelines to a certain extent.

[0011] Furthermore, the temperature control mechanism includes a heating box, a cooling box, a first circulating pump, a second circulating pump, a heating pipe and a cooling pipe. The heating box is connected to the first circulating pump, the first circulating pump is connected to the heating pipe, the heating pipe is connected to the heating box, the cooling box is connected to the second circulating pump, the second circulating pump is connected to the cooling pipe, and the cooling pipe is connected to the cooling box.

[0012] By adopting the above technical solution, when the hydrogen storage system is running, the heating box is used to provide a heat source to heat the hydrogen storage tank in a low temperature environment; the cooling box cools the hydrogen storage tank in a high temperature environment or under overheating conditions. The two are connected to the corresponding heating pipe and cooling pipe through the first circulation pump and the second circulation pump respectively to form a circulation loop of hot and cold media: when heating is required, the first circulation pump transports the hot medium from the heating box to the heating pipe, and then flows back to the heating box; when cooling is required, the second circulation pump transports the cooling medium from the cooling box to the cooling pipe, and then flows back to the cooling box. This circulation system achieves the goal of controllable and adjustable temperature, ensuring that the hydrogen in the hydrogen storage tank is in a stable thermodynamic environment to improve hydrogen storage efficiency and system safety.

[0013] Furthermore, the heating tube and the cooling tube are arranged in a spiral at the bottom of the hydrogen storage tank, and the heating tube and the cooling tube are arranged in a serpentine and staggered manner around the hydrogen storage tank.

[0014] By adopting the above technical solution, the heating tubes and cooling tubes are spirally arranged at the bottom of the hydrogen storage tank, and arranged in a serpentine staggered manner around the tank body, which can increase the contact area with the bottom and sides of the hydrogen storage tank, making the heat transfer at the bottom and sides more sufficient and uniform. The spiral and serpentine structures can effectively avoid the problem of uneven temperature in local areas and reduce thermal stress concentration. In this way, the internal environment of the hydrogen storage tank can be quickly heated up or cooled down during work, which improves the temperature control efficiency and overall stability, thereby ensuring that hydrogen can be safely stored and released under different working conditions.

[0015] Furthermore, the control mechanism includes a control component, an anti-recoil component and a connecting pipe, the connecting pipe is connected to the control component, the control component is firmly connected to the tank body, the anti-recoil component is connected to the protection mechanism, the anti-recoil component is firmly connected to the tank body, an air inlet is provided on the connecting pipe, an air outlet is provided on the connecting pipe, the air inlet is connected to the air inlet pipe, the air inlet and the air outlet are both located at the upper end of the tank body, the air outlet is connected to the tank body, the entrance end of the connecting pipe is spiral, and the bottom of the connecting pipe is meshed.

[0016] By adopting the above technical solution, the control mechanism uses the connecting pipe as the main channel to control the flow of hydrogen. One end of the connecting pipe is connected to the control component, and the other end is tightly connected to the tank body, and the bottom adopts a mesh design to achieve the purpose of heat exchange; the entry end is designed to be spiral, which can form eddies or disturbances during the flow process, which helps to mitigate the impact and evenly distribute the airflow. The air inlet and outlet on the connecting pipe are respectively connected to the air inlet pipe, the air outlet pipe and the upper end area of ​​the tank body, so that hydrogen can be introduced or discharged when needed. The anti-recoil component is connected to the protection mechanism and the tank body, which can effectively prevent reverse impact or sudden backflow of the airflow and improve safety performance.

[0017] Furthermore, the control component includes a control block, a rotating block, a control motor and a control elastic member. The control block is provided with a connecting hole, the connecting hole is connected to the protection mechanism, the connecting hole is connected to the tank body, the control block and the tank body are fastened together, the rotating block and the control block are slidingly connected, the control motor and the control block are fastened together, the control motor and the rotating block are transmission-connected, the control elastic member and the rotating block are fastened together, and the control elastic member and the control block are fastened together.

[0018] By adopting the above technical solution, the connecting hole set on the control block allows the protective mechanism to maintain gas communication with the tank body, so as to guide or discharge the gas in an emergency or normal operation. The rotating block and the control block are connected by sliding, which is convenient for rotation adjustment. After the control motor and the control block are tightened, they are connected to the rotating block through transmission, and can drive the rotating block to rotate when receiving a control command. The control elastic member is respectively tightened to the rotating block and the control block, which is used to provide a certain reset or buffer force after the rotating block is actuated to avoid overshoot or jamming. This structure enables the system to quickly and smoothly adjust or switch the gas path, enhancing the precise control and safety of the hydrogen flow.

[0019] Furthermore, the anti-recoil assembly includes a recoil block, a recoil elastic member and a fixed block. The recoil block is provided with an opening portion, the recoil block is provided with a closed portion, the inclination of the open portion is greater than the inclination of the closed portion, the recoil block and the recoil elastic member are fastened together, the recoil elastic member and the fixed block are fastened together, and the recoil block and the fixed block are slidably connected.

[0020] By adopting the above technical solution, the recoil block can move or change its angle under external force (such as gas impact). The opening and closing parts set thereon have different slopes, wherein the opening part has a larger slope, so it can be quickly opened when the gas impact is large to avoid excessive pressure accumulation; the closing part has a smaller slope, which is used to stably support the recoil block under normal working conditions. After the recoil elastic part is fastened to the recoil block and the fixed block, it provides an elastic reset force to ensure that the recoil block is in the initial position under normal circumstances. Once airflow recoil or sudden impact occurs, the recoil block moves smoothly to the opening, releases pressure or gas, and then returns to the closed position under the action of the elastic part. This design can effectively prevent backflow or shock waves from entering the hydrogen storage system in reverse, thereby improving the overall safety of the system.

[0021] Furthermore, the protection mechanism includes a separation component, a solid hydrogen storage block, a control valve, a protection tube and an inert gas tank, the connecting hole is connected to the solid hydrogen storage block, the solid hydrogen storage block is tightly connected to the tank body, the separation component is tightly connected to the mounting frame, the separation component is connected to the air outlet pipe, the control valve is connected to the protection tube, the control valve is connected to the tank body, the protection tube is connected to the inert gas tank, and the separation component is connected to the inert gas tank.

[0022] By adopting the above technical solutions, the solid hydrogen storage block in the protection mechanism can be used to absorb or release hydrogen, avoiding excessive pressure accumulation. After being firmly connected to the tank body, the solid hydrogen storage block can form an integrated safety buffer separation assembly that is firmly connected to the mounting bracket and is connected to the inert gas tank through the air outlet pipe, for filtering, separating or further purifying the gas. The control valve is connected to the protection pipe and the tank body and can be automatically opened or closed according to the monitoring signal. The protection pipe is connected to the inert gas tank and is used to inject or release inert gas to avoid the risk of hydrogen leakage or explosion. The cooperation of the entire protection mechanism can quickly handle abnormal situations, prevent the expansion of accidents, and improve the stability and safety of the hydrogen storage system operation.

[0023] Furthermore, the separation assembly includes a filtration motor, blades, a palladium alloy membrane and a filtration box. The filtration motor is firmly connected to the filtration box, the filtration motor is drivingly connected to the blades, the palladium alloy membrane is firmly connected to the filtration box, and the filtration box is connected to the inert gas tank.

[0024] By adopting the above technical solutions, the filtration motor drives the blades to rotate, causing the air flow to form a certain eddy current or swirl in the filtration box, so that the inert gas and hydrogen are separated. The palladium alloy membrane is fixed on the filtration box and can selectively allow hydrogen to pass through while blocking other gases or impurities, realizing the purification or recovery of hydrogen. The inert gas and impurities preliminarily separated by the filtration box can enter the inert gas tank for recovery or treatment. This process can not only effectively remove impurities and improve the purity of hydrogen, but also help reduce potential safety hazards and protect the subsequent hydrogen-using equipment.

[0025] Furthermore, the detection mechanism includes an intake valve, an outlet valve, a temperature sensor, a pressure sensor and a concentration sensor. The intake valve is connected to the intake pipe, the outlet valve is connected to the outlet pipe, the temperature sensor is firmly connected to the solid hydrogen storage block, the pressure sensor is firmly connected to the tank body, and the concentration sensor is firmly connected to the tank body.

[0026] By adopting the above technical solutions, the intake valve and the outlet valve are respectively connected to the intake pipe and the outlet pipe to control the opening or closing of the inlet and outlet air flows of the system. The temperature sensor is firmly connected to the solid hydrogen storage block and can monitor the temperature change of the solid hydrogen storage module in real time, facilitating the judgment of the hydrogenation or dehydrogenation process. The pressure sensor is installed on the tank body to detect the gas pressure in the tank and avoid overpressure or underpressure operation. The concentration sensor is firmly fixed on the tank body and can monitor the hydrogen concentration or the content of other components, and can issue an early warning when the concentration is abnormal. Through the cooperation of these monitoring devices, the detection mechanism can collect core parameters such as temperature, pressure, and concentration in real time, and cooperate with other mechanisms to adjust or trigger an alarm when needed, thus significantly improving the safety and maintainability of the hydrogen storage system.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] The spiral shape of the inlet end of the connecting pipe can form eddies or disturbances during the flow, which helps to mitigate impact and evenly distribute the airflow. After that, the heating pipe and the cooling pipe are spirally arranged at the bottom of the hydrogen storage tank, and serpentinely arranged around the tank body, which can increase the contact area with the bottom and sides of the hydrogen storage tank, making the heat transfer at the bottom and sides more sufficient and uniform. The spiral and serpentine structures can effectively avoid the problem of uneven temperature in local areas and reduce thermal stress concentration. The temperature-controlled solid hydrogen storage block is preheated through the connecting pipe and then discharged from the upper end of the tank body. When the solid hydrogen storage block stores hydrogen in a specific metal or alloy (such as LaNi5, TiFe, Mg-based alloy, etc.), hydrogen will combine with the metal lattice to form a hydride, which is released by increasing the temperature and controlled by reducing the temperature. The inert gas of argon is filled in the protective tube, thereby forming a A relatively closed or negative pressure "low oxygen" environment is formed, so that hydrogen is not easy to reach the flammable or explosion limit. At the same time, because the density of argon is greater than that of hydrogen, the unreacted hydrogen will be concentrated on the upper end of the tank with the injection of argon. At the same time, the rotating block and the control block are in an open state, and the argon squeezes the hydrogen through the connecting hole into the solid hydrogen storage block. Due to the increase in pressure, it reacts with the solid hydrogen storage block, and the recoil block in the anti-recoil assembly closes with the internal pressure. The hydrogen in the sealed tube is in the solid hydrogen storage block. When it needs to be discharged or excessive pressure is detected, it is transferred to another tank through the tank body or separated from hydrogen and argon through the palladium alloy membrane in the separation assembly. Hydrogen is discharged and argon is recovered. A very small amount can re-enter the tank with the argon to achieve the purpose of improving the purity of hydrogen, fully discharging the internal hydrogen and completely recovering and reusing it, which helps to reduce safety hazards and protect subsequent hydrogen equipment.

[0057] By adopting the above technical solution, the filter motor 511 drives the blade 512 to rotate, so that the airflow forms a certain vortex or swirl in the filter box 514, so that the inert gas and hydrogen are separated. The palladium alloy membrane 513 is fixed on the filter box 514, which can selectively allow hydrogen to pass through while blocking other gases or impurities to achieve hydrogen purification or recovery. The inert gas and impurities initially separated by the filter box 514 can enter the inert gas tank 55 for recovery or treatment. This process can not only effectively remove impurities and improve the purity of hydrogen, but also help reduce safety hazards and protect subsequent hydrogen equipment.

[0058] Furthermore, the detection mechanism includes an inlet valve 61, an outlet valve 62, a temperature sensor 63, a pressure sensor 64 and a concentration sensor 65. The inlet valve 61 is connected to the inlet pipe 12, the outlet valve 62 is connected to the outlet pipe 13, the temperature sensor 63 is firmly connected to the solid hydrogen storage block 52, the pressure sensor 64 is firmly connected to the tank body 11, and the concentration sensor 65 is firmly connected to the tank body 11.

[0059] By adopting the above technical solution, the air inlet valve 61 and the air outlet valve 62 are respectively connected to the air inlet pipe 12 and the air outlet pipe 13 to control the opening or closing of the inlet and outlet air flows of the system. The temperature sensor 63 is tightly connected to the solid-state hydrogen storage block 52, and can monitor the temperature changes of the solid-state hydrogen storage module in real time, so as to facilitate the judgment of the hydrogenation or dehydrogenation process. The pressure sensor 64 is installed on the tank body 11 to detect the gas pressure in the tank to avoid overpressure or underpressure operation. The concentration sensor 65 is fastened to the tank body 11, which can monitor the hydrogen concentration or other component content, and can issue an early warning when the concentration is abnormal. Through the coordination of these monitoring devices, the detection mechanism 6 can collect core parameters such as temperature, pressure, and concentration in real time, and cooperate with other mechanisms to make adjustments or alarm triggers when necessary, thereby significantly improving the safety and maintainability of the hydrogen storage system.

[0060] Working principle of the present invention: the spiral shape of the inlet end of the connecting pipe 43 can form eddies or disturbances in the flow process, which helps to mitigate impact and evenly distribute the airflow. Then, the heating pipe 35 and the cooling pipe 36 are spirally arranged at the bottom of the hydrogen storage tank 1, and are serpentinely arranged around the tank body 11, which can increase the contact area with the bottom and the surrounding side of the hydrogen storage tank 1, so that the heat transfer at the bottom and the surrounding side is more sufficient and uniform. The spiral and serpentine structures can effectively avoid the problem of uneven temperature in local areas and reduce thermal stress concentration. The solid hydrogen storage block 52 that is temperature-controlled is preheated through the connecting pipe 43 and then discharged from the upper end of the tank body 11. When the solid hydrogen storage block 52 stores hydrogen in a specific metal or alloy (such as LaNi5, TiFe, Mg-based alloy, etc.), hydrogen will combine with the metal lattice to form a hydride, which is released by increasing the temperature and controlled by reducing the temperature. The inert gas of argon is filled into the protective tube 54, thereby forming The relatively closed or negative pressure "low oxygen" environment makes it difficult for hydrogen to reach the flammable or explosive limit. At the same time, because the density of argon is greater than that of hydrogen, the unreacted hydrogen will be concentrated at the upper end of the tank body 11 as the argon is injected. At the same time, the rotating block 412 and the control block 411 are rotated in an open state, and the argon squeezes the hydrogen through the connecting hole 4111 to enter the solid hydrogen storage block 52. Due to the increase in pressure, the argon reacts with the solid hydrogen storage block 52, and the recoil block 421 in the anti-recoil component 42 is closed with the internal pressure. The hydrogen in the sealed tube is in the solid hydrogen storage block 52. When it needs to be discharged or when excessive pressure is detected, it is transferred to another tank body 11 through the tank body 11 or separated from hydrogen and argon through the palladium alloy membrane 513 in the separation component 51. The hydrogen is discharged and the argon is recovered. A very small amount can re-enter the tank with the argon to achieve the purpose of improving the purity of the hydrogen, fully discharging the internal hydrogen, and completely recycling and reusing it, which helps to reduce safety hazards and protect subsequent hydrogen-using equipment.
