Description

Technical Field

[0001] The present application relates to the technical field of aluminum molten hydrogen production, and in particular to an aluminum molten hydrogen production chamber. Background Art

[0002] An underwater unmanned submersible (UUV) is an unmanned submersible that is independent of a mother ship's power supply, can be remotely controlled or autonomously controlled, is recyclable and reusable, and can self-propel or glide underwater for extended periods. Hydrogen fuel cells utilize hydrogen, a clean secondary energy source, as fuel, directly converting chemical energy into electrical energy through a chemical reaction. They offer zero emissions, high energy density, low noise, and high efficiency. This technological advantage enables UUVs to operate longer and deeper underwater, making them a key development direction for future underwater power systems.

[0003] Hydrogen fuel cells used in underwater unmanned submersibles offer a variety of hydrogen supply methods, including liquid hydrogen storage, high-pressure hydrogen storage, metal hydrogen storage, methanol reforming, and the reaction of aluminum-based composite materials or compounds (such as sodium borohydride) with water. The production of hydrogen from aluminum-based composite materials by reacting with water integrates the production and storage processes, enabling immediate hydrogen production and use. The hydrogen pressure only needs to meet the fuel cell's medium pressure (approximately 0.5-0.7 MPa), significantly simplifying the technical steps involved in hydrogen energy utilization. Furthermore, the produced gas contains no side-effect impurities other than water vapor, making it a superior gas supply method.

[0004] In related technologies, the hydrogen production rate often fluctuates significantly due to factors such as the thermodynamics, kinetics, and reactant state of the aluminum-water reaction. To ensure a good match between the aluminum-water hydrogen production rate and the fuel cell's hydrogen consumption rate, water is typically sprayed onto the aluminum-based composite material powder pile to control the water flow and, in turn, the reaction progress. However, when the reactor is scaled up and positioned horizontally, the overall control of the water inflow to the reaction is greatly reduced, and the hydrogen production rate will continue to fluctuate significantly. Utility Model Content

[0005] Based on this, it is necessary to provide an aluminum-water hydrogen production chamber, which can control the segmented water inlet to make the aluminum-based materials in the chamber react in segments, effectively reduce the fluctuation of the hydrogen production rate, and achieve stable hydrogen production.

[0011] In one embodiment, the plurality of nozzles are evenly distributed above the corresponding reaction areas.

[0012] In one embodiment, the plurality of reaction areas are arranged along the length direction of the reaction chamber shell.

[0013] In one embodiment, the aluminum-water hydrogen production cabin further includes:

[0017] A hydrogen pipe, one end of which is connected to the other end of the gas collecting channel, and the other end of which passes through the reaction chamber shell to guide the hydrogen in the gas collecting channel out.

[0018] In one embodiment, a thermal insulation layer is provided on the inner wall of the reaction chamber shell avoiding the gas collecting groove and on the outer wall of the gas collecting groove.

[0019] In one embodiment, the reaction chamber housing comprises:

[0024] A through-tank pipe is provided, wherein the through-tank pipe passes through the closed end plate assembly and the loading end plate assembly, and a heat insulation layer is attached to the inner wall of the through-tank pipe.

[0025] The aforementioned aluminum-liquid hydrogen production chamber utilizes an improved water spray system, enabling multiple nozzle assemblies to operate independently, spraying water at different reaction zones within the aluminum-based material.

[0045] Referring to Figures 1 to 3, the aluminum liquid hydrogen production chamber includes a reaction chamber shell 1 and a water spray system 2. A reaction space is set in the reaction chamber shell 1, and the reaction space is used to accommodate aluminum-based materials. The water spray system 2 includes a water supply pipeline and multiple nozzle assemblies 22. The water supply pipeline is used to supply water to the multiple nozzle assemblies 22 respectively, and can individually control the opening and closing of the water supply to each nozzle assembly 22. The multiple nozzle assemblies 22 are set in the reaction space and can spray water to the aluminum-based material, and the multiple nozzle assemblies 22 are respectively aimed at different reaction areas 10 of the aluminum-based material.

[0046] By improving the water spray system 2, multiple nozzle assemblies 22 operate independently, spraying water at different reaction zones 10 of the aluminum-based material. This facilitates control of the water spray volume and achieves a more uniform spray. By rotating the water spray from multiple nozzle assemblies 22, the aluminum-based material within the reaction shell undergoes a staged reaction, significantly improving the controllability of the hydrogen production process, effectively reducing fluctuations in the hydrogen production rate, and achieving a stable hydrogen production rate.

[0047] In some embodiments, as shown in Figures 1 and 4 , the reaction chamber housing 1 includes a housing body 11, a closed end plate assembly 12, and a loading end plate assembly 13. Ports are provided at both ends of the lengthwise direction of the housing body 11. The closed end plate assembly 12 covers the port at the left end of the housing body 11, and the loading end plate assembly 13 covers the port at the right end of the housing body 11. The loading end plate assembly 13 includes a loading port 1311, through which aluminum-based materials are loaded and unloaded from the reaction space.

[0048] The aluminum-liquid hydrogen production chamber can be used as the hydrogen supply system for the power compartment of an underwater unmanned submersible. The underwater unmanned submersible also includes other functional compartments, and each end of the aluminum-liquid hydrogen production chamber needs to be connected to the other functional compartments, generally using bolts. Furthermore, depending on the design requirements of the underwater unmanned submersible, the aluminum-liquid hydrogen production chamber and other functional compartments can typically adopt a cylindrical structure.

[0049] As shown in Figures 1 and 5 , the closed end plate assembly 12 includes a closed end plate 121 and a first compartment connector 122. The closed end plate 121 covers the port at the left end of the sealed shell body 11. The closed end plate 121 and the first compartment connector 122 can be configured as an integrated structure. The first compartment connector 122 is provided with threaded holes for bolts to connect. The first compartment connector 122 can be welded to the shell body 11 for a secure, sealed connection without the need for additional seals.

[0050] As shown in Figures 1 and 4 , the loading end plate assembly 13 includes a loading end plate 131 and a second compartment connector 132. The loading end plate 131 covers the port at the right end of the hull body 11. The loading end plate 131 and the second compartment connector 132 can be configured as an integrated structure. The first compartment connector 122 is provided with threaded holes for bolts to connect. The second compartment connector 132 can be welded to the hull body 11 for a secure, sealed connection without the need for additional seals.

[0051] Furthermore, as shown in Figures 1 and 4 , a charging port 1311 is provided on the charging end plate 131. To seal the charging port 1311 during the hydrogen production reaction, the charging end plate assembly 13 also includes a flange cover 133 and a flange connector 134. The flange connector 134 is connected around the charging port 1311 and extends outward from the shell body 11. The flange cover 133 covers the opening of the flange connector 134. Specifically, the flange cover 133 is detachably connected to the flange connector 134 via a circle of bolts.

[0052] The aluminum-liquid hydrogen production chamber requires material transportation, power supply, and communication with other functional layers. To this end, as shown in Figures 1 and 2 , the chamber also includes a through-hole 5, which passes through the closed end plate assembly 12 and the loading end plate assembly 13. A thermal insulation layer is applied to the inner wall of the through-hole 5. As shown in Figure 4 , the loading end plate 131 is provided with a through-hole 1312 for the through-hole 5 to pass through.

[0053] By setting up a through-cabin pipe 5 that passes through the closed end plate 121 and the loading end plate 131, the through-cabin pipe 5 forms a through-cabin structure that is completely isolated from the reaction space. The through-cabin pipes 5, communication harnesses, power harnesses, etc. used in other functional compartments of the unmanned submersible are passed through the through-cabin pipe 5 to ensure material transportation, power supply, and communication between the compartments of the unmanned submersible.

[0054] Optionally, the through-tank pipe 5 is provided on the upper portion of the shell body 11, substantially at the same height as the nozzle assembly 22. The through-tank pipe 5 effectively utilizes the upper water distribution space in the reaction chamber shell 1 without damaging the overall pressure-bearing structure of the reaction chamber shell 1, resulting in a compact structure and high integration.

[0055] Referring to Figure 3 , the water supply pipeline includes multiple water supply branches 21, each nozzle assembly 22 being connected to a water supply branch 21. These water supply branches 21 penetrate the reaction chamber shell 1 and are equipped with valves for controlling the opening and closing of these branches. Assigning a separate water supply branch 21 to each nozzle assembly 22 facilitates control over the start and stop of water supply and the amount of water flowing to each nozzle assembly 22.

[0056] Specifically, the nozzle assembly 22 includes a nozzle connecting pipe 221 and multiple nozzles. One end of the nozzle connecting pipe 221 is connected to the water supply branch pipe 21, and the other end is provided with multiple branches, each branch connected to a nozzle, so that multiple nozzles can spray water on the aluminum-based material in the same reaction area 10. As shown in Figure 4, the loading end plate 131 is provided with a water inlet pipe hole 1313 for the water supply branch pipe 21 to pass through. The water supply branch pipe 21 is connected to the water inlet end of the nozzle connecting pipe 221. The water supply branch pipe 21 branches out the spray water through the nozzle connecting pipe 221 and then sprays it from multiple nozzles. This increases the spray range through multiple nozzles to ensure that all aluminum-based materials in the corresponding reaction area 10 are sprayed.

[0057] Optionally, a plurality of nozzles are evenly distributed above the corresponding reaction area 10 so that the aluminum-based material in the corresponding reaction area 10 is sprayed more evenly, which is beneficial to improving the reaction stability.

[0058] In some embodiments, as shown in FIG2 , a plurality of reaction regions 10 are arranged along the length of the reaction chamber shell 1. No clear dividing line is required between the plurality of reaction regions 10; the aluminum-based material can be placed in the middle and lower portion of the reaction chamber shell 1, leaving space for the upper water spray system 2. Multiple reaction regions 10 are naturally separated according to the spray range of each nozzle assembly 22. In this embodiment, three reaction regions 10 are provided. Of course, three or fewer reaction regions 10 can also be provided based on parameters such as the length and diameter of the aluminum-liquid hydrogen production chamber, and this is not limited here.

[0059] 2 and 3 , the present embodiment is provided with three nozzle assemblies 22, and each nozzle connecting pipe 221 includes a first water distribution pipe 2211, a second water distribution pipe 2212 and a water distribution pipe 2213. The first water distribution pipe 2211 is connected to the corresponding water supply branch pipe 21, and the water supply branch pipe 21 passes through the loading end plate 131 and enters the interior of the reaction chamber shell 1 and is connected to the middle part of the first water distribution pipe 2211; the two ends of the first water distribution pipe 2211 are respectively connected to the middle part of the second water distribution pipe 2212; the second water distribution pipe 2212 is arranged parallel to the inner surface of the reaction chamber shell 1; the ends of the second water distribution pipe 2212 are respectively connected to the middle part of the water distribution pipe 2213; the water distribution pipe 2213 is arranged horizontally with both ends blocked, and the lower part of the water distribution pipe 2213 is provided with a plurality of evenly distributed vertically downward water distribution holes, and the plurality of water distribution holes form nozzles to spray water on the aluminum-based material. The water distribution process of the multiple water distribution holes is uniform, and uniform water dripping can be achieved in each water distribution pipe 2213. Of course, in other embodiments, more water distribution pipes can be set as needed to separate more water distribution pipes 2213 to cover a larger area of ​​the reaction area 10.

[0060] Optionally, the aluminum liquid hydrogen production chamber further includes a hydrogen collection system 3, which is used to cool and collect the hydrogen generated in the reaction space.

[0061] Specifically, the hydrogen collection system 3 includes a gas collecting tank 31 and a hydrogen pipe 32. The gas collecting tank 31 is connected to the inner wall of the reaction chamber shell 1 and, together with the reaction chamber shell 1, forms a gas collecting channel. One end of the gas collecting channel is provided with an opening. One end of the hydrogen pipe 32 is connected to the other end of the gas collecting channel. The other end of the hydrogen pipe 32 passes through the reaction chamber shell 1 to discharge the hydrogen in the gas collecting channel and supply it to other hydrogen-consuming units. As shown in Figure 4, the loading end plate 131 is provided with a hydrogen pipe hole 1314 for the hydrogen pipe 32 to pass through.

[0062] 2 and 6 , the gas collecting tank 31 is a square trough-shaped structure. The top of the gas collecting tank 31 is sealed and welded to the inner surface of the reaction chamber shell 1 to form a gas collecting channel therebetween as a hydrogen heat dissipation channel. The left end of the gas collecting tank 31 is open and the right end is closed. Since the left end of the gas collecting tank 31 is away from the hydrogen pipe 32, the residence time of the hydrogen during discharge can be extended, thereby achieving a better heat exchange effect.

[0063] Furthermore, as shown in Figure 6, an insulation layer 4 is provided on the inner wall of the reaction chamber shell 1, away from the gas collecting groove 31, and on the outer wall of the gas collecting groove 31. This prevents excessive heat dissipation from the aluminum-liquid hydrogen production chamber due to the UUV's excessive speed, ensuring that the aluminum-liquid hydrogen production reaction proceeds at an appropriate reaction temperature. The insulation layer 4 is preferably made of breathable, low-heat-transfer aerogel fiberglass. The thickness of the insulation layer 4 is designed and adjusted based on the ambient water temperature and speed of the UUV.

[0064] Optionally, as shown in FIG1 , the aluminum liquid hydrogen production chamber further includes a displacement tube 6, which passes through the loading end plate 131 and communicates with the reaction space inside the reaction chamber shell 1. As shown in FIG4 , a displacement tube hole 1315 is provided at the lower portion of the loading end plate 13 for the displacement tube 6 to pass through.

[0065] The working process of the aluminum water hydrogen production cabin is as follows:

[0066] First, nitrogen gas is introduced through displacement pipe 6 to create a nitrogen atmosphere inside reaction chamber shell 1. Then, aluminum-based composite material is added to reaction chamber shell 1 through loading port 1311. After loading, the nitrogen gas flow is stopped, and flange cover 133 is bolted to flange connector 134, sealing the interior of reaction chamber shell 1.

[0067] Then, the aluminum liquid hydrogen production cabin is connected to other functional cabins of the underwater unmanned submersible by bolts through the first cabin section connector 122 and the second cabin section connector 132, and then the aluminum liquid hydrogen production cabin and other functional cabins are connected to form an integral structure.

[0068] Then, the multiple water supply branches 21 of the water spray system 2 are connected to the water supply system of the underwater unmanned submersible, the displacement pipe 6 is connected to the displacement system of the underwater unmanned submersible, and the hydrogen pipe 32 is connected to the hydrogen purification system of the underwater unmanned submersible.

[0069] After the above operations are completed, the replacement gas source is changed, hydrogen is introduced from the replacement pipe 6, and exhaust is carried out from the hydrogen pipe 32 and the subsequent purification system outlet to replace the gas inside the reaction chamber shell 1 to form a higher-purity hydrogen environment, so as to directly provide higher-purity hydrogen for the fuel cell. After the replacement is completed, the introduction of hydrogen is stopped.

[0070] Afterwards, the reaction water is supplied to the first water supply branch 21 of the water spray system 2. When the reaction water reaches the middle of the first water branch 2211 along the water supply branch 21, the reaction water is divided into two flow directions, flowing to the two ends of the first water branch 2211 respectively; when the reaction water reaches the middle water of the second water branch 2212, the reaction water is divided into two flow directions again, flowing to the two ends of the second water branch 2212 respectively; when the backwater reaches the middle of the water distribution pipe 2213, the reaction water is divided into two flow directions for the third time, flowing to the two ends of the water distribution pipe 2213 respectively; dripped into the first reaction area 10 of the corresponding aluminum-based composite material through the water distribution hole, thereby realizing a staged reaction. When the aluminum-based composite material in the first reaction area 10 is reacted, the reaction of the second reaction area 10 can be started, and the water inlet and water distribution method are the same as the first reaction area 10, and this is repeated until the last reaction area 10 reacts. By controlling the segmented water inlet, thereby realizing the segmented reaction, the fluctuation of the hydrogen production rate can be effectively reduced, and the hydrogen production amount can be stabilized.

[0071] Afterwards, when the reaction produces hydrogen, a certain hydrogen pressure is formed in the reaction chamber shell 1. Driven by the pressure, the hydrogen passes through the insulation layer 4 to reach the hydrogen collection system 3 and flows in the gas collecting channel formed by the gas collecting tank 31 and the reaction chamber shell 1. During the flow of hydrogen, the heat in the hydrogen will be transferred to the ambient water through the reaction chamber shell 1 in contact with the external water body, thereby realizing the cooling of the hydrogen; the cooled hydrogen is transported to the subsequent hydrogen purification system through the hydrogen pipe 32.

[0072] A large amount of heat generated during the aluminum-water reaction is conducted from the inside of the aluminum-based material to the reaction chamber shell 1. The reaction chamber shell 1 is in direct contact with the ambient water body. The heat is steadily dissipated into the ambient water body through heat conduction and heat convection, thereby achieving heat dissipation of the reaction chamber shell 1.

[0073] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
