Description

Technical Field

[0001] The invention belongs to the technical field of hydrogen storage equipment, and in particular relates to an aluminum-made modular titanium-based solid-state hydrogen storage equipment that can be replaced by a single tube. Background Art

[0002] Solid-state hydrogen storage equipment is generally composed of solid-state hydrogen storage materials, stainless steel shells, air pipe channels, filters, cooling fins, valves and heating / heat dissipation pipes. By introducing heat exchange media of different temperatures (the commonly used medium is water), the solid-state hydrogen storage materials are heated or cooled to achieve the purpose of hydrogen release and absorption.

[0003] According to the principle of heat exchange, hydrogen storage equipment is generally designed according to the design method of shell and tube heat exchanger, and baffles, tube sheets, sealing plates, etc. are set. The equipment is generally manufactured by welding. Finally, the single hydrogen storage tube (the smallest unit for loading hydrogen storage materials) is passed through the baffle in turn and fixed on the tube sheet to complete the assembly of the whole set of equipment.

[0004] In order to overcome the disadvantage of heavy weight of solid-state hydrogen storage equipment, the newly emerging vehicle-mounted solid-state hydrogen storage equipment such as bicycles and electric vehicles on the market also use aluminum shells, but they are small in size and have limited hydrogen storage capacity.

[0005] Defects and shortcomings of the existing technology:

[0006] Equipment made of stainless steel: The shell is connected by welding, which is easy to deform, making it difficult to assemble a single hydrogen storage tube and taking a long time to manufacture the shell. It also requires a lot of cost to control the quality of the weld, and there is a risk of cracking in the weld during long-term use.

[0007] After the single tube is installed in the shell, it is sealed as a whole by a sealing plate to form a complete set of hydrogen storage equipment. Therefore, it is impossible to replace a single tube. When the hydrogen is released, the whole set of equipment can only be filled with hydrogen. Solid-state hydrogen storage equipment is generally heavy, and it is difficult to replace the entire equipment with hydrogen. If there is no hydrogen filling station near the terminal, the vehicle will need to consume some hydrogen during the filling process, which increases the cost of use and also increases the difficulty of promoting solid-state hydrogen storage.

[0008] When inspecting a single tube, the sealing plate needs to be opened to inspect the single tube in the equipment, and the circulating water needs to be discharged for each inspection. In addition, considering that the single tube may need to be extracted during inspection, the seal between the single tube and the tube sheet generally uses a rubber soft seal, which is not fixed by welding, so there is a risk of leakage at the soft seal. Overall, the operation and maintenance cost of the equipment after commissioning will be very high.

[0009] It is difficult to replace the entire set of integrated hydrogen storage equipment, which is not conducive to setting up backup equipment.

[0010] Newly emerged aluminum equipment on the market: Aluminum shells formed by aluminum alloy casting that have emerged on the market are generally used for on-board solid-state hydrogen storage equipment. The current application scope is mostly concentrated on hydrogen bicycles and hydrogen electric vehicles. A single hydrogen storage tube generally uses a 0.39L gas cylinder, and the internal space of the aluminum shell can accommodate 1 or 2 bottles. This type of hydrogen storage equipment can realize single-bottle plug-in and replacement of hydrogen filling, but the gap between the gas cylinder and the internal storage space of the hydrogen storage equipment is large, the thermal resistance is large, and the heat exchange efficiency is low. Moreover, most of this type of equipment is cast as a whole, and the upper limit of the hydrogen storage capacity of each device has been set at the beginning of the design. When the hydrogen storage capacity needs to be increased, the devices cannot be assembled and can only be re-cast;

[0011] In view of this, an aluminum modular titanium-based solid-state hydrogen storage device with single-tube replaceability is proposed. Summary of the invention

[0012] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0013] In view of the following technical problems in the prior art: Equipment made of stainless steel: The shell is connected by welding, which is easy to deform, resulting in difficulty in assembling a single hydrogen storage tube and a long shell manufacturing cycle. It is also necessary to invest a lot of cost to control the quality of the weld, and there is a risk of cracking in the weld during long-term use. After the single tube is loaded into the shell, it is sealed as a whole by the sealing plate to form a complete set of hydrogen storage equipment. Therefore, it is impossible to replace the single tube. When the hydrogen is released, the whole set of equipment can only be filled with hydrogen. Solid-state hydrogen storage equipment is generally heavy, and it is difficult to replace the entire equipment with hydrogen. If there is no hydrogen filling station near the terminal, the vehicle needs to consume part of the hydrogen during the hydrogen filling process, which increases the cost of use and the difficulty of promoting solid-state hydrogen storage. When a single tube is overhauled, the sealing plate needs to be opened to realize the inspection of the single tube in the equipment, and the circulating water must be discharged for each inspection. In addition, considering the situation that the single tube may need to be extracted during maintenance, the seal between the single tube and the tube sheet generally adopts rubber soft seal, which is not fixed by welding, so there is a risk of leakage at the soft seal. Overall, the operation and maintenance cost of the equipment after it is put into use will be very high. It is difficult to replace the entire set of hydrogen storage equipment, which is not conducive to setting up backup equipment. New aluminum equipment on the market: The aluminum shell formed by aluminum alloy casting that has emerged on the market is generally used for on-board solid-state hydrogen storage equipment. The current application scope is mostly concentrated on hydrogen bicycles and hydrogen electric vehicles. The single hydrogen storage tube generally uses a 0.39L gas cylinder, and the internal space of the aluminum shell can accommodate 1 or 2 bottles. This type of hydrogen storage equipment can realize the plug-in and unplug of a single bottle, and replace and refill hydrogen, but the gap between the gas cylinder and the internal storage space of the hydrogen storage equipment is large, the thermal resistance is large, and the heat exchange efficiency is low. Moreover, most of this type of equipment is cast as a whole, and the upper limit of the hydrogen storage capacity of each device has been set at the beginning of the design. When the hydrogen storage capacity needs to be increased, the various devices cannot be assembled and can only be re-cast.

[0014] In order to solve the above technical problems, the present invention provides the following technical solutions: an aluminum modular titanium solid-state hydrogen storage device capable of single-tube replacement, comprising a lower shell, an intermediate shell and an upper shell;

[0015] The middle parts of the lower shell, the middle shell and the upper shell are all provided with a circulating water storage chamber, the front part of the lower shell is connected with a water inlet pipe, and the front part of the upper shell is connected with a water outlet pipe;

[0016] The upper surface of the lower shell, the upper and lower surfaces of the intermediate shell, and the lower surface of the upper shell are all provided with gas cylinder storage grooves, and the upper surface edge of the lower shell and the upper surface edge of the intermediate shell are both provided with spring storage grooves;

[0017] A single hydrogen storage tube is placed in the gas cylinder storage tank, and the single hydrogen storage tube is filled with a hydrogen storage alloy.

[0018] As an optimal technical solution for an aluminum modular titanium-based solid-state hydrogen storage device that can be replaced by a single tube, the back positions of the lower shell, the middle shell and the upper shell are all connected to circulating water pipe joints, the water inlet pipe, the circulating water storage chamber and the circulating water pipe joint on the lower shell are interconnected, the circulating water storage chamber and the circulating water pipe joint on the middle shell are interconnected, and the water outlet pipe, the circulating water storage chamber and the circulating water pipe joint on the upper shell are interconnected.

[0019] As a preferred technical solution for an aluminum modular titanium-based solid-state hydrogen storage device that can be replaced by a single tube, a circulating water telescopic pipe is connected to the two circulating water pipe joints with two openings facing each other.

[0020] As an optimal technical solution for an aluminum modular titanium-based solid-state hydrogen storage device that can be replaced by a single tube, spring compression columns are installed on the lower surface edge of the intermediate shell and the lower surface of the upper shell edge, and the size of the spring storage groove matches the size of the spring compression column.

[0021] As an optimal technical solution for a single-tube replaceable aluminum modular titanium-based solid-state hydrogen storage device, the outlet of the single hydrogen storage tube is threadedly connected with an integrated filtering and explosion-relief bottle mouth valve, and a collector is assembled on the upper shell, and the collector is connected to the upper shell through collector fasteners.

[0022] As an optimal technical solution for a single-tube replaceable aluminum modular titanium-based solid-state hydrogen storage device, the integrated filtering and explosion-venting bottle mouth valve and the collector are both connected with PU air pipes, and multiple PU air pipes are connected by quick-plug connectors.

[0023] As an optimal technical solution for a single-tube replaceable aluminum modular titanium-based solid-state hydrogen storage device, the side positions of the lower shell, the middle shell and the upper shell are all connected by locking buckles, and a spring is installed in the spring storage groove.

[0024] Beneficial effects of the present invention:

[0025] Compared with equipment made of stainless steel:

[0026] 1. The aluminum shell used in this aluminum modular titanium solid-state hydrogen storage device has high thermal conductivity, fast heat transfer, shortened response time of hydrogen release by the device, and light overall weight.

[0027] 2. The risk of shell leakage is low. The aluminum shell is made by casting. It only needs to set the casting process holes and seal them later. There is no sealing requirement for the contact between the aluminum seamless gas cylinder and the shell.

[0028] 3. It is conducive to long-distance hydrogen filling. Compared with the overall equipment, the weight of a single gas cylinder is greatly reduced, and transportation is easier.

[0029] 4. A spare gas cylinder can be set up. When the hydrogen in the gas cylinder on the equipment is exhausted, the spare gas cylinder can be replaced.

[0030] 5. It is convenient to carry out regular inspection and maintenance of gas cylinders.

[0031] Compared with the new aluminum equipment on the market:

[0032] 1. High thermal efficiency. When the locking buckle is closed, the gas cylinder and the shell are directly fitted together without any gap, and heat is directly transferred between the metals.

[0033] 2. Strong versatility. The intermediate shell is a universal module, and the intermediate shell can be increased, reduced or cancelled according to the different hydrogen amounts required by users.

[0034] In addition to the advantages of stainless steel and aluminum equipment alone, the present invention also has the following advantages:

[0035] 1. The mold is simple, and there is no special deflection structure inside the shell. Each shell is only provided with a water inlet and a water outlet. When the circulating water passes through the shell from bottom to top, the circulating water can be deflected, thereby improving the heat transfer efficiency.

[0036] 2. The number of molds is small, and the intermediate shell is a universal module. When the user needs different amounts of hydrogen, it can be achieved by simply adjusting the number of intermediate modules without the need to re-open the mold. The collector, upper shell and lower shell are fixed sizes, and the water inlet, outlet and circulating water interface can be processed separately later. The shell of the entire set of equipment only requires four sets of molds.

[0037] 3. Each gas cylinder is equipped with a bottle valve, which can realize the control of a single gas cylinder. Take the attached figure of the present invention as an example: when only the upper shell and the lower shell are combined, the number of gas cylinders is four. When the user's hydrogen demand is lower than the hydrogen storage capacity of the four gas cylinders, the user can choose to close the excess gas cylinder mouth valves. Similarly, when the intermediate shell is installed, the number of gas cylinders in the equipment is eight. When the hydrogen demand is lower than the hydrogen storage capacity of the eight gas cylinders, the user can choose to close the excess gas cylinder mouth valves. In addition to the measure of closing the bottle mouth valve, the required number of gas cylinders can also be directly filled, and other similar usage situations will not be listed one by one.

[0038] 4. The production cycle is short. The shell and collector described in the present invention can be mass-produced in advance as standard parts and can be kept in stock. The gas cylinder is a conventional aluminum seamless gas cylinder with a threaded outlet. The hydrogen storage material can be loaded at any time, so the gas cylinder can also be kept in stock. The remaining auxiliary accessories are all conventional parts and can be purchased temporarily or kept in stock. Therefore, it can be said that the main components of this equipment can be produced in a modular manner and kept in stock. When there is an order, it is only necessary to select the appropriate number of modules for assembly according to the amount of hydrogen required by the customer.

[0039] 5. The application scenarios are wider. The equipment described in the present invention can be freely combined, and the equipment can also be connected in parallel by setting pipelines at the outlet of the collector, so as to realize occasions with different hydrogen consumption amounts.

[0040] 6. Low investment cost. For suppliers, the mold is simple and the number of molds is small, the initial mold cost investment is small, and modular production is more conducive to reducing production costs. For users, the supplier's investment cost is low, and the user's procurement cost will also be reduced. In addition, the equipment has a simple structure and is easy to use. The aluminum shell is cast and formed, with fewer parts prone to defects and a low risk of leakage. The gas cylinder can be taken out separately for regular inspection, which reduces the user's operation and maintenance burden.

[0041] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the description and the drawings.

[0056] Example

[0057] Reference Figure 1 , 2 , 3 and 5, an aluminum modular titanium solid-state hydrogen storage device capable of single-tube replacement comprises a lower shell 1, an intermediate shell 2 and an upper shell 3;

[0058] A circulating water storage chamber 20 is provided in the middle of the lower shell 1, the middle shell 2 and the upper shell 3;

[0059] The front position of the lower shell 1 is connected to a water inlet pipe 5, the front position of the upper shell 3 is connected to a water outlet pipe 6, and the back positions of the lower shell 1, the intermediate shell 2 and the upper shell 3 are all connected to circulating water pipe joints 8. The water inlet pipe 5, the circulating water storage chamber 20 and the circulating water pipe joint 8 on the lower shell 1 are interconnected, the circulating water storage chamber 20 and the circulating water pipe joint 8 on the intermediate shell 2 are interconnected, the water outlet pipe 6, the circulating water storage chamber 20 and the circulating water pipe joint 8 on the upper shell 3 are interconnected, and a circulating water telescopic pipe 7 is connected between two circulating water pipe joints 8 with openings facing each other, and each circulating water pipe joint 8 and the circulating water telescopic pipe 7 together constitute a circulating water channel.

[0060] Reference Figure 3 , 6 , 7 and 8, the upper surface of the lower shell 1, the upper and lower surfaces of the intermediate shell 2 and the lower surface of the upper shell 3 are all provided with a gas cylinder storage groove 17, the upper surface edge of the lower shell 1 and the upper surface edge of the intermediate shell 2 are all provided with a spring storage groove 18, the lower surface edge of the intermediate shell 2 and the lower surface of the upper shell 3 are all provided with a spring compression column 19, and the size of the spring storage groove 18 matches the size of the spring compression column 19;

[0061] Reference Figure 3 A hydrogen storage single tube 10 is placed in the gas cylinder storage tank 17, and a hydrogen storage alloy 11 is filled in the hydrogen storage single tube 10. A filtering and explosion-proof integrated bottle mouth valve 12 is threadedly connected at the outlet of the hydrogen storage single tube 10. A collector 15 is assembled on the upper shell 3, and the collector 15 is connected to the upper shell 3 through a collector fastener 16. PU air pipes 13 are connected to the filtering and explosion-proof integrated bottle mouth valve 12 and the collector 15, and multiple PU air pipes 13 are connected by quick-plug connectors 14, wherein the filtering and explosion-proof integrated bottle mouth valve 12, the PU air pipe 13, the quick-plug connector 14 and the collector 15 together constitute a hydrogen release channel.

[0062] Reference Figure 3 and 4 The side positions of the lower shell 1, the middle shell 2 and the upper shell 3 are all connected by a locking buckle 4, and a spring 9 is installed in the spring storage groove 18.

[0063] Working principle: when the hydrogen is used up, close the integrated filtering and explosion-proofing bottle mouth valve 12, open the locking buckle 4, and the spring 9 plays a lifting role, so that the various shells are separated from each other. In this process, the force of the spring 9 distributed from top to bottom is increasing, which is convenient for the middle shell 2 and the upper shell 3 to lift up part of the space, and disconnect the PU air pipe 13 connecting the integrated filtering and explosion-proofing bottle mouth valve 12 and the quick-plug connector 14 from the quick-plug connector 14, so that the hydrogen storage single tube 10 can be smoothly taken out; when the hydrogen storage single tube 10 is filled with hydrogen, it is inserted into the original position, the locking buckle 4 is closed, and the PU air pipe 13 is reconnected to complete the single tube replacement work.

[0064] When releasing hydrogen, hot water is introduced through the water inlet pipe 5. The hot water first reaches the circulating water storage chamber 20 of the lower shell 1 through the water inlet pipe 5, and enters the circulating water storage chamber 20 of the intermediate shell 2 with the cooperation of the circulating water telescopic pipe 7 and the circulating water pipe joint 8, and finally enters the circulating water storage chamber 20 of the upper shell 3 and is discharged through the water outlet pipe 6. The water flows from the lower shell 1 to the intermediate shell 2 and the upper shell 3 through the circulating water telescopic pipe 7, and the hydrogen storage alloy 11 in the hydrogen storage single tube 10 releases hydrogen after absorbing heat; after the hydrogen is released, it flows into the PU air pipe 13 through the integrated filtering and explosion-proof bottle mouth valve 12, and finally converges to the collector 15, and the collector 15 releases hydrogen to the outside in a unified manner, wherein the outlet of the collector 15 can be equipped with a pressure reducing valve and various connecting joints according to the requirements of the user terminal.

[0065] When this device is used in a vehicle-mounted scenario, the hydrogen release temperature of the titanium solid-state hydrogen storage material is 20-65°C, and the water discharged from the fuel cell can be used as heating circulating water. The main material of this device is aluminum alloy, considering that the lighter the weight of the vehicle-mounted equipment, the better, and the disadvantage of solid-state hydrogen storage is its heavy weight, so using aluminum as the main material of the device can reduce the overall weight of the vehicle.

[0066] When this equipment is used in non-vehicle-mounted fixed hydrogen source scenarios, it is mostly used in large quantities in parallel. In order to facilitate lifting and replacement, aluminum is used as the main material, and the effect of reducing weight is particularly obvious; aluminum alloy has high thermal conductivity, and titanium-based solid hydrogen storage materials have low heat requirements when releasing hydrogen, and only conventional hot water units are required to achieve hydrogen release.

[0067] Regarding material selection, comprehensive consideration is required. Aluminum alloy materials are easier to form than stainless steel materials, which is conducive to mass production and reduces costs. At the same time, the strength and other mechanical properties of aluminum alloy materials can also meet the pressure and temperature requirements of equipment design, and have good corrosion resistance.

[0068] It should be understood that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but for those of ordinary skill having the benefit of this disclosure, the development effort will be a routine task of design, fabrication, and production without undue experimentation.

[0069] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
