Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen storage equipment, and in particular to a solid-state hydrogen pool unit, module, operating system and heat exchange system. Background Art

[0002] As a renewable secondary energy source, hydrogen energy has attracted widespread attention due to its pollution-free and environmentally friendly characteristics during the conversion and utilization process. Especially in the automotive field, hydrogen energy is regarded as a potential energy source to replace traditional fossil fuels and is widely used in hydrogen fuel cell power systems. In a hydrogen fuel cell engine system, hydrogen and oxygen react under the action of an electrochemical catalyst to generate electrical energy and heat energy. However, the low density of hydrogen leads to its low storage density. In order to meet the long-range requirements of hydrogen fuel cell vehicles, the hydrogen storage system needs to work at a higher pressure, which also raises the issue of energy consumption during the hydrogen storage process. Even if hydrogen is compressed to 35MPa or 70MPa, the hydrogen storage density is still difficult to meet the long-range requirements of commercial heavy trucks.

[0003] In the current hydrogen energy storage technology, in order to improve the hydrogen storage density, metal hydrogen storage materials have become an important choice. Usually, these metal hydrogen storage materials are made into solid hydrogen storage units in the form of powder, cube and other regular shapes or spheres, irregular polyhedrons and other forms. However, when metal hydrogen storage materials store hydrogen in the form of loose powder, it is difficult to accurately control the reaction rate during the hydrogen hydrolysis release process, and the hydrogen storage cylinder is easily damaged under high-pressure operation; while the hydrogen storage monomers in the shape of spheres or other irregular polyhedrons have a large change in the area in contact with the liquid, so it is difficult to control the hydrogen release rate; and in both implementation methods, after the solid hydrogen storage material contacts the liquid, the heat conduction efficiency in the hydrogen release process is low, and the heat generated by the reaction cannot be conducted and dissipated, resulting in high temperatures in local areas, which can easily cause safety hazards.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Solid-state hydrogen storage materials are one of the key materials for achieving high hydrogen storage density and are widely used in the field of hydrogen energy storage. According to different characteristics, solid-state hydrogen storage materials can be divided into two categories: reversible hydrogen storage materials and irreversible hydrogen storage materials. Reversible hydrogen storage materials can restore their original state during repeated hydrogenation and discharge, and are suitable for large-scale hydrogen energy storage and recycling; while irreversible hydrogen storage materials can only store hydrogen in one hydrogenation process, and cannot be recharged after hydrogenation, and are usually used for one-time hydrogen storage applications.

[0048] From the perspective of chemical composition, solid-state hydrogen storage materials can also be divided into two categories: metal hydrogen storage materials and non-metallic hydrogen storage materials. Metal hydrogen storage materials generally include metal hydrides and hydrogen storage alloys, which show good performance in the process of hydrogen absorption and release and are widely used in high-density hydrogen storage systems. Common metal hydrogen storage materials include metals such as magnesium (Mg), calcium (Ca), and aluminum (Al), which react with hydrogen to form hydrides and can store hydrogen at relatively high densities. Specifically, hydrogen storage alloys are an important category of metal hydrogen storage materials, which store hydrogen by combining with hydrogen to form hydrides. Hydrogen storage alloys can be divided into binary, ternary, and multi-element alloys according to the complexity of their components. For example, binary hydride alloys such as magnesium hydride (MgH2), calcium hydride (CaH2), and aluminum hydride (AlH3) have a high theoretical hydrogen storage density in hydrogen storage. With the continuous development of alloying technology, the emergence of multi-element hydrogen storage alloys has further improved the hydrogen storage capacity and hydrogen release performance of hydrogen storage alloys. Materials such as sodium hydride (NaH) and potassium hydride (KH) are also being explored as potential high hydrogen storage density materials at a certain stage of research. Inorganic ionic compound hydrogen storage materials are another type of high-efficiency hydrogen storage materials, mainly including coordination hydrides and amino compounds. Coordination hydrides, such as sodium aluminum hydride (NaAlH4) and lithium borohydride (LiBH4), are compounds with very high hydrogen storage density, which store hydrogen through coordination reactions. Sodium aluminum hydride, in particular, has been proven to be a candidate material with high hydrogen storage density and good cycle performance. Amino compounds, such as ammonia borane (NH2BH3), have a higher theoretical hydrogen storage density and good chemical stability at room temperature.

[0049] Lithium batteries store and release electricity as a secondary energy source, while solid-state hydrogen pools use hydrogen energy as a secondary energy source for storage. The energy storage density of solid-state hydrogen pools is usually more than 10 times that of lithium batteries. If hydrogen is converted into electricity through a fuel cell, assuming that the efficiency of the fuel cell is 50%, then the energy density of the solid-state hydrogen pool after conversion into electricity is still close to 10 times that of a lithium battery. At present, the selection of hydrogen storage materials must meet a high degree of reversibility requirements, that is, the ability to repeatedly absorb, store and release hydrogen, and its cycle life (the number of reversible cycles) must also meet certain standards, such as at least more than 5,000 times. Although many high-density hydrogen storage materials have been discovered, high-density hydrogen storage materials with strong stability often require high temperatures to release hydrogen, while unstable high-density hydrogen storage materials are difficult to control due to their fast reaction speed.

[0050] The embodiment of the present application provides a solid-state hydrogen pool unit, an operating system and a heat exchange system, which solves the problem that when the metal hydrogen storage material in the prior art stores hydrogen in the form of loose powder, it is difficult to accurately control the reaction rate during the hydrogen hydrolysis and release process, and the hydrogen storage cylinder is easily damaged under high-pressure operation; and the hydrogen storage monomer using a spherical or other irregular polyhedral shape has a large change in the area of ​​contact with the liquid, so it is difficult to control the hydrogen release rate; and in both implementation methods, after the solid hydrogen storage material contacts the liquid, the heat conduction efficiency in the hydrogen release process is low, and the heat generated by the reaction cannot be conducted and dissipated, resulting in a high temperature in the local area, which is easy to cause safety hazards. In the present application, multiple groups of solid-state hydrogen pool units are installed inside the hydrogen release reaction tank after being vertically inserted side by side through a quick-release frame, which effectively improves the storage density of solid-state hydrogen storage materials and supports modular expansion; by adjusting the height of the hydrolyzed liquid level in the reaction chamber to ensure the consistency of the reaction and the consistency of the liquid distribution, the hydrogen release rate of the solid hydrogen storage material is accurately controlled; the solid-state hydrogen pool unit cooperates with the hydrogen release subsystem and the heat exchange system to achieve functions such as rapid external replacement, system-level signal interaction, provision of heat exchange energy, and rapid discharge of tail liquid.

[0051] Please refer to the following examples for details:

[0052] Reference Figure 1-Figure 2 , the present invention provides an embodiment of a solid-state hydrogen pool unit, the specific structure includes: a solid-state hydrogen storage material 12, in order to ensure the structural stability of the solid-state hydrogen storage material 12 during use, a columnar solid-state hydrogen storage material 12 is adopted, and a highly corrosion-resistant metal support frame 11 is evenly nested and filled inside. This metal support frame 11 not only enhances the mechanical strength of the hydrogen storage material, but also effectively prevents deformation or damage of the material due to hydrogen release or environmental changes during long-term use. The support frame 11 and the peripheral frame 13 are designed to be detachably connected, which is convenient for rapid disassembly during maintenance or replacement. By controlling the flow rate of the hydrolyzed liquid entering the hydrogen pool, the contact area between the solid-state hydrogen storage material 12 and the hydrolyzed liquid can be indirectly controlled, and then the release rate of hydrogen can be accurately controlled, ensuring the stability and adjustability of hydrogen release, and meeting the safety and efficiency requirements under different working conditions.

[0053] Furthermore, the design of the support frame 11 pays more attention to modularity and maintainability. The support frame 11 is equipped with a quick disassembly module, including a quick-release frame 14 and a corrosion-resistant quick-screw threaded column 15: the quick-release frame 14 is located at the top of the support frame 11, and can be quickly disassembled or assembled with the support frame 11, which simplifies the operation process and reduces maintenance time. The threaded column 15 is connected by a rotation, so that the support frame 11 and the peripheral frame 13 can be easily and quickly connected or disassembled, ensuring the modular assembly of the overall system.

[0054] Please continue to refer to Figure 1-Figure 2 In this embodiment, a hydrogen release port 131 is provided at the top of the peripheral frame 13 for safely and efficiently releasing hydrogen. During use, hydrogen flows out smoothly through the release port, avoiding hydrogen accumulation in the system, thereby ensuring the safety and stability of the hydrogen storage system. Among them, the position and size of the hydrogen release port 131 can be calculated according to the operating requirements and design schemes of different vehicles to ensure that the hydrogen release rate can be effectively adjusted under different working conditions, while minimizing possible gas leakage or pressure fluctuations.

[0055] Exemplarily, the bottom sides of the peripheral frame 13 are respectively provided with a hydrolyzate inlet 132 and a hydrolyzate outlet 133. The hydrolyzate inlet 132 is used to transport the hydrolyzate to the inside to react with the solid hydrogen storage material 12 to release hydrogen, and the hydrolyzate outlet 133 is used to discharge the hydrolyzate after the reaction to ensure the circulation of the liquid in the system. In addition, in order to accurately monitor important parameters such as the liquid, pressure and temperature inside the system, multiple groups of liquid level detection points 134 are set at different heights on one side of the peripheral frame 13 to monitor the liquid level of the internal hydrolyzate in real time, and feed back data information to the control system through sensors and automation systems to achieve real-time regulation of the liquid level, so as to control the contact area between the hydrolyzate and the solid hydrogen storage material 12, and then accurately control the release rate of hydrogen. In addition, the other side of the peripheral frame 13 is also provided with a pressure detection point 135 and a temperature detection point 136, which are also distributed at different heights so that the changes in pressure and temperature can be fully and accurately monitored during the operation of the entire system. The pressure detection point 135 is used to monitor the gas pressure inside the frame to ensure that the internal pressure is at a safe value; the temperature detection point 136 is used to measure the temperature change in the system in real time to avoid affecting the hydrogen release efficiency or internal stability due to excessively high or low temperature.

[0056] Reference Figure 3-Figure 4 The present invention also provides a solid hydrogen pool module 2, including: a hydrogen release reaction tank 21, a liquid flow port 211 and a reactant discharge port 212 are arranged on both sides of the hydrogen release reaction tank 21, and a liquid flow port 211 and a reactant discharge port 212 are arranged on both sides of the hydrogen release reaction tank 21, respectively. The liquid flow port 211 is used to introduce the required hydrolyzate, and the discharge port is used to discharge the reacted substance, so as to ensure smooth liquid circulation during the reaction process and avoid liquid accumulation or retention.

[0057] In order to optimize the hydrogen release efficiency, the reaction area in the hydrogen release reaction tank 21 is divided into a plurality of reaction chambers 214 by chamber partitions 213. These reaction chambers 214 can accommodate multiple groups of solid hydrogen pool units 1, and can be quickly and conveniently installed through the quick-release frame 14. After the solid hydrogen pool unit 1 is vertically inserted, it is firmly installed inside each reaction chamber 214, thereby effectively improving the storage density of the solid hydrogen storage material 12, which not only improves the space utilization, but also ensures the high efficiency of hydrogen release.

[0058] Specifically, two or more adjacent reaction chambers 214 are divided into a plurality of confluence chambers 215 at the top of the reaction chambers 214 by the upward extension of the chamber partition 213. The confluence chamber 215 helps to evenly distribute the gas and liquid, ensuring that the gas and liquid flow more smoothly during the reaction process, avoiding local accumulation or uneven flow, and ensuring that hydrogen continuously and stably enters the fuel cell system to provide electrical energy for the vehicle, so that the electrical energy generated by the fuel cell passes through the electric drive and transmission device of the entire vehicle.

[0059] Furthermore, a heat exchange plate 22 is provided at the bottom of the reaction chamber 214, and a heat exchange cavity 221 is formed inside the heat exchange plate 22. A coolant inlet 222 and a coolant outlet 223 are respectively provided on both sides of the heat exchange plate 22. The heat released by the reaction is exchanged with the coolant flowing in the serpentine plate-fin flow channel inside the heat exchange cavity 221 (this part of the technical solution belongs to the prior art and is therefore not drawn and marked in the figure), thereby achieving rapid conduction and dissipation of the heat generated during the reaction to the outside, effectively avoiding changes in the performance of the solid hydrogen pool material or incomplete reaction caused by excessively high temperature during the reaction, and ensuring the stability of the reaction process and the efficiency of hydrogen release.

[0060] In order to further improve the flexibility and expandability of the hydrogen release reaction tank 21, the tank body supports modular expansion, and the scale of the reaction tank can be adjusted according to the actual hydrogen demand and hydrogen storage capacity. The modular design enables the solid-state hydrogen pool unit 1 to achieve a high degree of interchangeability. Users can quickly replace or adjust the hydrogen storage material according to actual needs, greatly enhancing the adaptability and flexibility of the system.

[0061] Specifically, the solid hydrogen pool unit 1 in each reaction chamber 214 can quickly install the solid hydrogen storage material 12 in place by quick plugging or hanging as needed. The partition design between the chambers ensures the uniformity of liquid distribution, and the height of the hydrolyzed liquid level can be accurately controlled during the reaction, thereby ensuring the consistency of the hydrolysis reaction. In this way, the speed of hydrogen release can be accurately controlled, thereby maintaining a stable hydrogen flow rate and good dispersion of the fluid, ensuring the high efficiency of the reaction.

[0062] Reference Figure 5The present invention also provides an embodiment of a solid-state hydrogen pool operation system, the solid-state hydrogen pool operation system includes the solid-state hydrogen pool module 2 as in the above embodiment, and also includes:

[0063] The hydrogen pool composite plate unit is used to replace the solid hydrogen pool unit 1. The composite plate contains gas distribution channels and liquid distribution channels to ensure sufficient contact and reaction between hydrogen and hydrolyzed liquid. By adjusting the volume ratio of the hydrolyzed liquid, the release rate of hydrogen can be accurately controlled to ensure stable hydrogen supply of the fuel cell system under different working conditions;

[0064] The hydrogen pool heat exchange manifold unit is used to conduct heat inside the solid hydrogen pool unit 1 to maintain the system temperature within a reasonable range. It is composed of a heat exchange pipe and a distribution manifold, and ensures the system temperature control effect through heat exchange between the coolant and the reaction chamber 214;

[0065] The pressure signal acquisition unit and the temperature signal acquisition unit are used to collect the operating parameters inside the solid-state hydrogen pool unit 1. They are composed of high-precision sensors and signal processing modules. The pressure sensors are usually installed at key positions of the hydrogen pool (such as gas inlet, outlet, etc.) to monitor changes in internal pressure. The temperature sensors are distributed in multiple areas of the hydrogen pool to collect temperature data in real time. These data can provide key operating information for the subsequent control system to ensure the stable operation of the hydrogen pool.

[0066] The hydrogen cell system control unit is used to control the operation of the entire subsystem. It can use a high-performance microprocessor and embedded software system, monitor various sensor data in real time, and ensure the stability of the hydrogen cell system under different working conditions through a closed-loop control mechanism. The unit can process and control the operation of various electrical components, use a unified CAN signal for data transmission, simplify signal interaction, and improve transmission efficiency and reliability, thereby ensuring coordination with the upstream control system.

[0067] The hydrogen pool tail liquid storage unit is used to process the tail liquid after the reaction, including a sealed container and a liquid delivery pipeline connected to it. The tail liquid storage container is designed with corrosion-resistant and highly sealed materials to effectively prevent tail liquid leakage or environmental pollution. During the tail liquid treatment process, through cooperation with other system modules, the safe treatment and reuse of the tail liquid is guaranteed to avoid potential impact on the hydrogen pool system;

[0068] The hydrogen storage buffer device of the hydrogen pool is used to buffer the hydrogen generated by the solid-state hydrogen pool unit 1 to cope with the instantaneous demand for hydrogen by the fuel cell system. The buffer device is composed of a high-strength airtight container and a gas flow regulating device. The flow is controlled by a regulating valve, so that excess hydrogen can be stored when the demand for hydrogen is low, and hydrogen can be supplied in time during peak demand to ensure the stability of the hydrogen pool system.

[0069] The hydrogen pool cooling and heat exchange device is used to recycle the heat inside the solid hydrogen pool unit 1. Through the design of the circulating coolant flow channel and the multi-layer heat exchange plate 22, the heat generated during the hydrogen release process is effectively taken away to prevent the system from overheating;

[0070] The hydrogen cell electrical control device is used to transmit control signals of different electrical units. It integrates various electrical components (such as relays, switches, sensors, actuators, etc.) and transmits control signals through circuit boards. Its design has explosion-proof and anti-interference functions to deal with potential safety hazards in hydrogen environments.

[0071] Specifically, the hydrogen cell electrical control device is electrically connected to the pressure signal acquisition unit, the temperature signal acquisition unit, the hydrogen cell system control unit, the hydrogen cell tail liquid storage unit and the hydrogen cell system control unit.

[0072] Reference Figure 6 The present invention also provides an embodiment of a solid-state hydrogen pool heat exchange system 4, which is used to circulate heat exchange for the solid-state hydrogen pool module 2 in the above embodiment, and the solid-state hydrogen pool heat exchange system 4 includes:

[0073] The temperature detection sensor and the pressure detection sensor are used to detect the operating parameters inside the solid-state hydrogen pool unit 1. The temperature sensor can measure the temperature change inside the solid-state hydrogen pool unit 1, and the pressure sensor can monitor the pressure condition of the system, and then adjust the running speed of the water pump and the flow rate of the coolant in real time, so as to effectively adjust the heat emission and hydrogen release rate of the system, and ensure that the system can operate stably under different workloads;

[0074] The circulating water pump is used to circulate the coolant into the solid hydrogen pool unit 1 to take away the heat released by the internal reaction. The coolant first enters the solid hydrogen pool unit 1 and takes away the excess heat through heat exchange with the inside of the hydrogen pool to keep the temperature of the system stable. The coolant after heat exchange is then processed through the filter and radiator;

[0075] The radiator is used to circulate and dissipate the heat released by the reaction in the solid-state hydrogen pool unit 1, and effectively dissipate the heat released by the solid-state hydrogen pool unit 1 to the environment through the cooperation of the external heat dissipation core and the heat dissipation fan;

[0076] The filter is connected to the water pump and radiator, and is mainly used to filter impurities in the coolant to ensure that the coolant flows smoothly and avoid the deposition of impurities that may affect the efficient operation of the cooling system;

[0077] The replenishing tank is used to replenish the lost coolant to ensure stable and sufficient liquid circulation in the system.

[0078] Temperature and pressure sensors monitor the system's operating status in real time, and automatically adjust the water pump speed and coolant flow rate based on real-time data to ensure the stability of the system under different load conditions. By intelligently adjusting the coolant flow rate and temperature according to changes in temperature and pressure, the system is able to optimize heat release and hydrogen adsorption and release efficiency. This efficient thermal management and control strategy ensures the safe, stable and efficient operation of the solid-state hydrogen pool unit 1 in various working environments, thereby improving the overall performance of hydrogen storage and release.

[0079] Through the above technical scheme, the solid-state hydrogen pool unit 1 of the present application realizes functions such as rapid external replacement, system-level signal interaction, provision of heat exchange energy, and rapid discharge of tail liquid by cooperating with the hydrogen release subsystem 3 and the heat exchange system. This design can not only utilize the heat in the hydrogen release process to support the low-temperature start of the vehicle, but also recover the reaction products, thereby ensuring that the solid-state hydrogen pool unit 1 and its related systems can maintain safe, reliable and efficient operation under various operating conditions.
