Technical Field
[0001] The present application relates to the technical field of solid hydrogen storage, and in particular to a hydrogen storage and transportation system. Background Art
[0002] Hydrogen energy, known as the cleanest energy with the greatest development potential in the 21st century, is clean and environmentally friendly, has high energy density per unit mass, is renewable, has a wide range of sources, has high energy conversion efficiency when used in fuel cells, has low noise, and has zero emissions. It is a secondary energy source with great development prospects and is of great significance to alleviating environmental pollution and energy crises. Hydrogen refueling stations, as the infrastructure for refueling fuel cell vehicles, play an important role in the hydrogen energy industry.
[0003] The technologies for hydrogen storage and transportation are mainly divided into the following three categories: gaseous storage and transportation, liquid storage and transportation, and solid storage and transportation. There are mainly high-pressure hydrogen storage and transportation, pipeline hydrogen transportation, low-temperature liquefied storage and transportation, organic liquid storage and transportation, ammonia as a carrier storage and transportation, metal hydride storage and transportation, adsorption storage and transportation, and other hydrogen storage and transportation technologies. In the storage and filling technology of hydrogen refueling stations, currently international and domestic hydrogen refueling stations mainly use high-pressure storage and transportation technology. Although high-pressure hydrogen storage equipment has the advantages of simple structure, low energy consumption for preparation, and rapid charging and discharging, due to the low density of hydrogen, the high-pressure hydrogen storage density is low, the equipment is bulky, and the storage and transportation efficiency is low. Because the pressure is very high, there are safety risks such as easy leakage and explosion during the storage and transportation process.
[0004] Hydrogen solid storage and transportation technology, such as metal hydride hydrogen storage, has high mass hydrogen storage density and volume hydrogen storage density. For example, the mass hydrogen storage density of magnesium-based hydrogen storage material is 7.6%, and the volume hydrogen storage density is 110kg / m 3 , hydrogenation and dehydrogenation speeds are fast, it can be stored at room temperature and pressure, it is easy to transport, it can be recycled and recovered, and there is basically no three wastes during the preparation process.
[0005] At present, the solid storage and transportation system integrates or skids the tanks for storing hydrogen storage materials, the heating and heat extraction modules, and the control system. The whole system has the functions of absorbing, releasing, and storing hydrogen, and the transportation and storage of hydrogen is achieved through overall transportation. This hydrogen storage method is easy to use, but as a whole hydrogen storage and transportation system, the entire system or skid needs to be transported during the transportation process, which has the problems of low hydrogen storage and transportation efficiency and inflexible operation. At the same time, the long-term transportation and handling of the hydrogen storage system will affect its service life.
[0006] Therefore, in response to the above technical problems, how to design a hydrogen storage and transportation system with high storage and transportation efficiency, flexible operation, and reduced damage to the hydrogen storage and release system caused by transportation and handling that affects its service life is a technical problem that technical personnel in this field need to solve.

DETAILED DESCRIPTION
[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0043] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0044] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper", "lower", "front", "back", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0045] In this embodiment, a hydrogen storage and transportation system is provided, which includes a hydrogen storage module, a hydrogenation module and a hydrogenation release module. The present application separates the functions of the hydrogen storage system through modular design, and the core module of hydrogen storage, namely the hydrogen storage module, is skid-mounted for transportation, thereby improving the efficiency of hydrogen storage and transportation, and making transportation, storage and distribution more flexible; the complex, bulky, easily damaged, moving equipment, and parts requiring public works support are designed as hydrogenation modules and hydrogenation release modules, which are placed at the hydrogenation source and hydrogen use site respectively, and do not participate in the transportation of hydrogen, which not only reduces transportation and handling and increases its service life, but also can be fixed for use in nearby public works conditions.
[0046] like Figure 1 As shown, the hydrogen storage module includes at least one hydrogen storage tank, each hydrogen storage tank includes a hydrogen storage material 9, a heater 16 and a temperature sensor 10 spaced apart from the hydrogen storage material 9, and a connection port 7 located at the end of the hydrogen storage tank and connected to the hydrogen storage material 9; Figure 2As shown, the hydrogenation module includes a distribution tube bundle 4 connected to the connection port 7 and providing hydrogen to the hydrogen storage tank, a fixed heat extraction cavity 5 for inserting and fixing all hydrogen storage tanks, and a hydrogenation temperature control system 18 for displaying the temperature of the temperature sensor 10. The fixed heat extraction cavity 5 is also used to cool the hydrogen storage tank. The hydrogenation temperature control system 18 adjusts the cooling degree of the fixed heat extraction cavity 5 according to the temperature of the temperature sensor 10; Figure 4 As shown, the hydrogen desorption module includes a collecting tube bundle 13 which is connected to the connecting port 7 and collects the hydrogen in the hydrogen storage tank, an insulation chamber 14 for inserting and fixing all the hydrogen storage tanks, and a hydrogen desorption temperature control system 17 for displaying the temperature of the temperature sensor 10. The hydrogen desorption temperature control system 17 adjusts the heating temperature of the heater 16 according to the temperature of the temperature sensor 10.
[0047] A locking device is provided in the above-mentioned connecting port 7. When the hydrogen storage tank is connected to the distribution tube bundle 4 or the collecting tube bundle 13, the front end of the distribution tube bundle 4 or the collecting tube bundle 13 will push open the locking device, so that the hydrogen storage tank is connected to the distribution tube bundle 4 or the collecting tube bundle 13; when the hydrogen storage tank is removed from the distribution tube bundle 4 or the collecting tube bundle 13, the connecting port 7 is separated from the distribution tube bundle 4 or the collecting tube bundle 13, the locking device is automatically closed, and the hydrogen storage tank is sealed to ensure that the residual hydrogen in the hydrogen storage tank does not leak.
[0048] In addition, a heater sleeve 8 in contact with the hydrogen storage material 9 is provided in the hydrogen storage tank, where the sleeve 8 may be a metal sleeve and has a heat conduction function; one end of the heater sleeve 8 is fixedly connected to the bottom of the hydrogen storage tank, and may be connected by welding or other means, but the heater sleeve 8 itself is open, ensuring that the heater 16 can be inserted into the heater sleeve 8; the other end of the heater sleeve 8 extends into the hydrogen storage tank and is closed, ensuring that the inserted heater 16 can be completely isolated from the hydrogen storage material 9 and can withstand the temperature and pressure during the hydrogenation and dehydrogenation process.
[0049] A temperature sensor sleeve different from the heater sleeve 8 is also provided in the hydrogen storage tank. The temperature sensor sleeve is in contact with the hydrogen storage material. One end of the temperature sensor sleeve is fixedly connected to the bottom of the hydrogen storage tank and is open; the other end extends into the hydrogen storage tank and is closed; the temperature sensor sleeve forms a sealed connection with the hydrogen storage tank; and the temperature sensor sleeve is used to insert the temperature sensor 10.
[0050] Of course, the temperature sensor 10 can be set in the temperature sensor sleeve, or fixed to the temperature remote signal 22 in the hydrogenation module and the dehydrogenation module, and inserted into the temperature sensor sleeve of the hydrogen storage tank when in use.
[0051] In order to effectively reduce the shaking and volume expansion of the hydrogen storage material 9 in the hydrogen storage tank, in this embodiment, an internal part for dividing the hydrogen storage material 9 into multiple independent spaces is provided in the hydrogen storage material 9. The internal part can be a metal mesh or a sintered alloy, and of course other parts can also be used, including but not limited to the two methods given above.
[0052] It should be noted that the heat transfer efficiency between the hydrogen storage material 9 and the hydrogen storage tank wall can be enhanced by setting a heat conducting sheet in the hydrogen storage tank. According to the calculation results of the Fluent software, the shape, thickness, distribution position and other parameters of the heat conducting sheet are optimized. At the same time, it is necessary to consider adding a small amount of auxiliary materials to increase the thermal conductivity of the hydrogen storage material 9 during molding. This will not be described in detail here and can be set according to actual conditions.
[0053] Based on the above embodiments, Figure 2 As shown, the hydrogenation module also includes a hydrogen compressor 1, a hydrogen heat exchanger 2 and an inlet filter 3 which are connected in sequence, and the three are connected, and the inlet filter 3 is also connected to the distribution tube bundle 4 to ensure that hydrogen can be added to the hydrogen storage tank. It should be noted that safety relief measures need to be set up on the pipeline from the back of the hydrogen compressor 1 to the distribution tube bundle 4 to ensure a safe working environment; before the hydrogen enters the hydrogen storage tank, it needs to pass through the inlet filter 3 to protect the hydrogen storage material 9 inside it; after the hydrogen passes through the hydrogen compressor 1, a hydrogen heater or a hydrogen heat exchanger 2 needs to be set up to meet the temperature or pressure requirements of the hydrogen.
[0054] If the hydrogen source is high-pressure hydrogen and meets the pressure requirement of hydrogenation, the hydrogen compressor 1 may not be provided. The raw hydrogen may be high-pressure hydrogen with complex conditions. If the raw hydrogen pressure does not reach the design value, the hydrogen pressure setting value may be reached by providing the hydrogen compressor 1. In addition, a hydrogen recovery pipeline and valve may be provided on the pipeline from the back of the hydrogen compressor 1 to the distribution tube bundle 4, so that the residual hydrogen in the system may be recovered after the hydrogenation is completed.
[0055] For the above-mentioned fixed heat extraction cavity 5, as Figure 3 As shown, a plurality of first openings are provided at both ends thereof, the first opening on one side is used for inserting the hydrogen storage tank, and the first opening on the other end is used for inserting the connecting port 7, and corresponds to the interface on the distribution tube bundle 4; the hydrogen storage tank can be connected to the distribution tube bundle 4 through the fixed heat extraction cavity 5.
[0056] In addition, the hydrogen storage tank needs to remain stable during the hydrogen refueling process, so a sealing lock buckle 6 for locking the hydrogen storage tank is set at the first opening. Of course, the sealing lock buckle 6 does not affect the normal insertion and removal of the hydrogen storage tank, and is only for fixing the hydrogen storage tank after insertion; the sealing lock buckle 6 is also used to seal the hydrogen storage tank and the fixed heat extraction cavity 5. Of course, the connection port 7 should also be sealed.
[0057] The fixed heat extraction cavity 5 is provided with a cooling water inlet 19 and a cooling water outlet 20. The cooling water enters the fixed heat extraction cavity 5 through the cooling water inlet 19, cools the hydrogen storage tank, and is discharged through the cooling water outlet 20. In combination with the above embodiment, after the hydrogen storage tank is inserted, the first openings on both sides can seal the heat extraction cavity 5 through the sealing lock 6 to prevent the cooling water in the cavity from leaking out. During the hydrogenation process, the cavity is a closed system and can withstand the internal pressure caused by the cooling water.
[0058] An anti-collision plate is set in the fixed heat extraction cavity 5 and at the position corresponding to the cooling water inlet 19 to prevent the cooling water from directly flushing the cavity and the hydrogen storage tank when entering the equipment; a baffle is installed in the fixed heat extraction cavity 5, and the cooling water flows along the baffle and forms a cross flow with the hydrogen in the hydrogen storage tank; a certain number of baffles perpendicular to the hydrogen storage tank are set in the cavity, so that the fluid can follow the prescribed path and flow horizontally through the hydrogen storage tank multiple times, increase the degree of turbulence, and improve the convective heat transfer coefficient between the hydrogen storage tanks. At the same time, the baffle bears part of the support and limiting role for the hydrogen storage tank. Of course, there are no more restrictions on the specific setting methods of the anti-collision plate and the baffle, which can be set according to actual conditions and fall within the protection scope of this application.
[0059] On the basis of the above-mentioned embodiment, the hydrogenation temperature control system 18 can display the temperature of each hydrogen storage tank according to the temperature of the temperature sensor 10 or the temperature remote transmission signal 22 in each hydrogen storage tank, and automatically or manually adjust the amount of cooling water entering according to the specific temperature. Of course, a temperature alarm device can also be set. When the hydrogenation temperature control system 18 displays that the temperature exceeds the set value, the corresponding temperature alarm device will sound an alarm to remind the staff.
[0060] like Figure 4 As shown, the hydrogen discharge module also includes an outlet control valve 11 and an outlet filter 12 connected in sequence. The outlet filter 12 is connected to the collecting tube bundle 13, and the hydrogen in the hydrogen storage tank is discharged by the outlet control valve 11; the hydrogen discharge temperature control system 17 can receive the remote pressure signal 21 of the hydrogen discharged by the outlet control valve 11, and adjust the pressure of the hydrogen sent out by the outlet control valve 11 according to the size of the remote pressure. In addition, during the hydrogen discharge process, the temperature remote signal 22 in each hydrogen storage tank is transmitted to the hydrogen discharge temperature control system 17, which can display the temperature in each hydrogen storage tank, and can control the power of the heater 16 in each hydrogen storage tank according to the temperature in each hydrogen storage tank. It should be noted that the heater 16 here can be an electric heater, and the electric heater is operated by setting a power supply.
[0061] Similarly, when the temperature displayed by the hydrogen discharge temperature control system 17 exceeds the set value, the corresponding temperature alarm device will sound an alarm. The remote pressure is displayed on the controller, and an alarm will also sound when the hydrogen pressure exceeds the set value.
[0062] For the pipeline between the outlet control valve 11 and the collecting pipe bundle 13, safety relief measures are also required to ensure that the staff is in a safe working environment. The outlet filter 12 can prevent dust from contaminating downstream equipment and pipeline instruments.
[0063] like Figure 5 As shown, the two ends of the heat preservation bin 14 are also provided with a plurality of second openings opened opposite to each other, a metal tube matching the outer wall of the hydrogen storage tank is provided between the two second openings opened opposite to each other, the hydrogen storage tank is inserted into the metal tube from one end, and the other end is connected to the collecting tube bundle 13. In order to achieve the heat preservation effect, a heat preservation material can be filled between the heat preservation bin 14 and the metal tube, and the heat preservation material can be selected from non-toxic, harmless, non-flammable inorganic or organic heat preservation materials, which will not be described in detail here.
[0064] Similar to the fixed heat extraction cavity 5 , a fixing buckle 15 for locking the hydrogen storage tank is provided at the second opening to ensure that the hydrogen storage tank can stably release hydrogen in the heat preservation chamber 14 .
[0065] In addition, a guide rail may be provided in the fixed heat extraction cavity 5 and at a position corresponding to the first opening. Similarly, a guide rail may also be provided in the metal tube, and the hydrogen storage tank may be inserted along the guide rail and smoothly communicate with the collecting tube bundle 13 or the distribution tube bundle 4 under the action of the guide rail. Of course, the guide rail needs to be fixedly provided and only plays the role of limiting, supporting and guiding.
[0066] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
[0067] Specific examples are used herein to illustrate the principles and implementation methods of the present application, and the description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
