However, the safety and reliability of high-pressure gas cylinders under current technology are difficult to guarantee.

[0003] Regarding real-time hydrogen production, considering the different application scenarios of hydrogen generation reaction devices compared to factory hydrogen production, factors such as the ease of replacement of consumables and the ease of maintenance of the device structure need to be considered.

[0017] Figure 1 This is a simplified cross-sectional view of the top-feed hydrogen generation reaction device according to an embodiment of the present invention. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Figure 1 This is a simplified cross-sectional view of the top-feed hydrogen generation reactor according to an embodiment of the present invention, wherein the structures involving common components are illustrated using common symbols.

[0020] This utility model discloses a top-feed hydrogen generation reaction device, including a reaction chamber 19 and a solid material support 12.

[0021] Specifically, the reaction chamber 19 has an internal reaction chamber that is divided into a liquid chamber 22 and a gas chamber 20 by a vertically arranged partition. The liquid chamber 22 and the gas chamber 20 are connected by a communication port 21 located at the bottom of the partition.

[0022] Specifically, the reaction chamber 19 is provided with a liquid injection port 9 communicating with the liquid chamber 22, a hydrogen exhaust port 10 communicating with the gas chamber 20, and an extension port 13 located directly above the gas chamber 20; the liquid injection port 9 is used to replenish the liquid reactants required for hydrogen generation.

[0023] The solid material support 12 has a hollow box structure and a storage chamber 17 located inside. Multiple micropores 15 communicating with the storage chamber 17 are provided on the surface of the solid material support 12.

[0024] The solid material support 12 extends into the reaction chamber 19 through the inlet 13. After the solid material support 12 is installed in place, the upper end of the solid material support 12 seals the inlet 13. The micropore 15 located at the bottom of the solid material support 12 is higher than the connecting port 21 to prevent hydrogen generated during the reaction from entering the liquid chamber 22.

[0025] Specifically, the solid material support 12 is used to store the solid reactants participating in the hydrogen production reaction, and the liquid reactants participating in the hydrogen production reaction are injected through the liquid injection port 9. In practical applications, when the hydrogen outlet 10 is closed, the distribution of the liquid reactants is shown in the attached figure. Figure 1 As shown, the liquid reactants fill the liquid chamber 22 and are partially injected into the bottom of the gas chamber 20. When the hydrogen outlet 10 is opened, the liquid reactant level in the gas chamber 20 rises and reacts with the solid reactants in the solid material support 12 through the micropores 15 to generate hydrogen. The generated hydrogen is discharged from the hydrogen outlet 10. When the hydrogen discharge rate is greater than the hydrogen generation rate, the liquid reactant level continues to rise, and more and more solid reactants come into contact with the liquid reactants to generate hydrogen, increasing the hydrogen generation rate. When the hydrogen discharge rate is equal to the hydrogen generation rate, the liquid reactant level remains stable. When the hydrogen outlet 10 is closed, hydrogen accumulates in the gas chamber 20. As the hydrogen pressure increases, the liquid reactants are discharged through the liquid inlet 9. When the solid reactants or solid reactant residues soaked in the liquid reactants no longer generate hydrogen, the hydrogen and liquid reactants reach pressure equilibrium.

[0026] Correspondingly, the closure or opening of the hydrogen outlet 10 can be controlled by an exhaust on / off valve 11.

[0027] In an optional embodiment, the partition and the reaction chamber 19 are an integral structure to ensure the structural strength of the partition.

[0028] Specifically, in order to store the liquid reactants discharged from the liquid inlet 9 and to replenish the required liquid reactants in the reaction chamber in a timely manner, the hydrogen generation reaction device during top feeding in this embodiment of the present invention further includes a liquid storage tank 3, wherein the liquid storage tank 3 has an internal liquid storage chamber 4, and the liquid storage chamber 4 is connected to the liquid inlet 9 of the liquid chamber 22 through a liquid storage outlet 6 located at the bottom.

[0029] Generally, the liquid level of the liquid reactants in the storage tank 4 needs to be kept higher than the liquid inlet 9, so that when liquid reactants need to be replenished in the reaction chamber, the liquid reactants can be spontaneously transported from the storage tank 4 to the reaction chamber by utilizing the pressure difference.

[0030] Furthermore, a pressure pump 7 is provided in the connection channel between the liquid storage tank 4 and the liquid tank 22, which can be used to actively increase the delivery pressure of the liquid reactants.

[0031] In addition, a liquid storage on / off valve 8 can be installed in the connection channel between the liquid storage tank 4 and the liquid tank 22. In practical applications, the liquid storage tank 3 and the reaction tank 19 can be physically isolated so that operations such as replenishing liquid reactants, cleaning the liquid storage tank 4, and replacing the liquid storage tank 4 can be safely performed on the side of the liquid storage tank 3.

[0032] In addition, in order to add liquid reactants and adjust the gas pressure balance in the liquid storage tank 4, a liquid filling port 5 can be provided on the top surface of the liquid storage tank 3.

[0033] Furthermore, a liquid recovery port 23 communicating with the liquid tank 22 is also provided on the reaction chamber 19; the liquid recovery port 23 is positioned lower than the liquid injection port 9 and higher than the communication port 21. To ensure the purity and cleanliness of the liquid reactants and avoid affecting hydrogen generation, the liquid recovery port 23 can be used to collect the liquid material in the reaction chamber, addressing any potential waste materials after the reaction.

[0034] Furthermore, the top-feed hydrogen generation reactor also includes a filtration module 1; the liquid recovery port 23 is connected to the input end of the filtration module 1. The liquid collected through the liquid recovery port 23 can be filtered through the filtration module 1. The physical structure of the filtration module 1 needs to be determined according to the form or type of waste; for example, if the hydrogen generation reaction formula is a reaction formula, the waste is generally in the form of particles, which can be filtered out of the liquid by a filter screen.

[0035] Generally, the output of the filter module 1 can be connected to the liquid storage tank 4 through a filter check valve 2 to recover the filtered pure liquid reactants in real time.

[0036] Similarly, the maintenance of the filter module 1 can be achieved by adding a recovery on / off valve 24 between the input end of the filter module 1 and the liquid recovery port 23.

[0037] Furthermore, regarding the installation method of the solid material support 12, an end cap is provided at the upper end of the solid material support 12, the periphery of the end cap is provided with threads, and a sealing ring 14 is provided below the end cap; The extension port 13 has a stepped structure, with a large end countersunk on the outside of the reaction chamber 19 and a small end step on the inside of the reaction chamber 19. The inner wall of the large end countersunk is machined with mating threads. When the solid material support 12 is installed into the reaction chamber 19 from the inlet 13, the end cap is threaded onto the mating thread of the countersunk end, and the sealing ring 14 is pressed against the step at the small end. In practice, since the internal pressure of the gas chamber 20 is not high, the number of turns of the mating thread does not need to be too many; it is sufficient to provide a certain locking ability for the sealing ring 14.

[0038] In addition, to facilitate the replacement of solid reactants in the solid material support 12, an end cap with a threaded fit can be installed on the solid material support 12 to facilitate the replacement of solid reactants. Furthermore, to prevent the hydrogen gas involved in the gas chamber 20 from overflowing when the solid reactants are replaced, a fixed cylinder 18 is provided in the reaction chamber. The upper end of the fixed cylinder 18 is open and connected to the reaction chamber body 19 and communicates with the extension port 13. The fixed cylinder 18 has a through groove 16 at a preset position on its outer edge. The micropores 15 on the solid material support 12 are formed at preset positions; When the solid material support 12 extends from the inlet 13 into the reaction chamber 19 and is not fully threaded onto the countersunk thread at the large end, the micro-hole 15 is not connected to the through groove 16, and the storage chamber 17 and the gas chamber 20 are not connected; when the solid material support 12 extends from the inlet 13 into the reaction chamber 19 and is threaded onto the countersunk thread at the large end, the micro-hole 15 is connected to the through groove 16, and the storage chamber 17 and the gas chamber 20 are connected.

[0039] For example, in Figure 1 In the schematic structure, when the solid material support 12 extends from the inlet 13 into the reaction chamber 19 and is threaded onto the countersunk thread of the large end, the micro-hole 15 communicates with the through groove 16, and the storage chamber 17 communicates with the gas chamber 20. When the solid material support 12 rotates 90°, the micro-hole 15 is no longer connected to the through groove, and the storage chamber 17 and the gas chamber 20 are temporarily isolated. At this time, opening the end cap to replace the solid reactant will not cause hydrogen leakage.

[0040] Furthermore, the reaction chamber can be equipped with multiple inlets 13 and multiple sets of solid material supports 12 to achieve uninterrupted continuous hydrogen production.

[0041] It should be noted that the top-feed hydrogen generation reactor provided in this embodiment generates a large amount of heat in some types of hydrogen production reactions. However, since the amount of liquid reactant in this embodiment can be replenished at any time, the heat can be discharged by circulating the liquid reactant, or the heat of reaction can be utilized for additional purposes to reduce energy loss. Regarding the quality of the generated hydrogen, if higher requirements are required for the produced hydrogen, it can be connected to a downstream hydrogen treatment device after the hydrogen outlet 10. This embodiment will not provide further details.

[0042] In summary, this utility model discloses a top-feed hydrogen generation reactor. This reactor uses a top-feed method to add solid reactants, and the hydrogen reaction process is automatically controlled by the pressure at the hydrogen outlet. The overall structure is simple, maintenance is easy, and reactant replenishment is simple. The solid reactants are designed and stored as consumables, which improves the convenience and safety of consumable transportation. By setting up multiple sets of solid material supports, uninterrupted hydrogen production can be achieved, ensuring the continuous operation of downstream equipment.
