Description

A multifunctional water-splitting hydrogen boiler Technical Field

[0001] This invention relates to the field of water splitting for hydrogen production technology, and specifically to a multifunctional water splitting hydrogen boiler. Background Technology

[0002] Hydrogen production has wide applications in industry, laboratories, energy, and the environment. Currently, hydrogen production can be categorized into several types: electrolytic hydrogen production, which uses an electric current to decompose water into hydrogen and oxygen; high-temperature steam hydrogen production, which produces hydrogen by reacting natural gas or other hydrocarbon compounds with steam; and chemical hydrogen production, among others.

[0003] According to patent number CN211255243U, published on August 14, 2020, a water-splitting hydrogen boiler is disclosed. A two-stage annular steam filter connected to the boiler steam is installed in the upper part of the boiler furnace. A high-temperature combustion reactor is installed in the lower part of the furnace. A disc-shaped steam-splitting hydrogen generator is partially buried in the upper part of the combustion reactor. A connecting pipe with varying sizes and widths is installed in the upper middle of the hydrogen generator. One end of the connecting pipe passes through the inner structure in the middle of the furnace and connects to the upper part of the steam filter in the upper part of the furnace. A hydrogen output pipe extends out of the lower part of the furnace body from the middle of the hydrogen generator. A gas distribution pipe is installed at the outlet of the output pipe. One end of the gas distribution pipe rotates back into the furnace and enters the lower middle of the combustion reactor.

[0004] In existing technologies, including the aforementioned patents, hydrogen is produced by decomposing high-temperature steam at temperatures above 950°C, and a portion of the produced hydrogen is recycled, thus saving energy. Currently, high-temperature steam is often generated by heating water, and then the gas pressure of the high-temperature steam is increased before it is released into a boiler to decompose water into hydrogen. However, in methods that use externally heated water systems to extract steam and pipe it into the boiler, heat is lost as the high-temperature steam passes through the pipes. Furthermore, because the steam is under high pressure within the pipes, its pressure decreases as it is released into the boiler. It is known that when high-pressure gas transforms into low-pressure gas, this process is usually accompanied by gas volume expansion. During this expansion, the gas does work, resulting in a decrease in its internal energy and a drop in temperature. Due to the decrease in temperature of the high-temperature steam entering the boiler, it is necessary to increase the temperature of the high-pressure steam entering the boiler and to insulate the pipes. However, increasing the temperature of the high-temperature steam also increases the cost of hydrogen production.

[0005] Summary of the Invention

[0006] The purpose of this invention is to provide a multifunctional water-splitting hydrogen boiler to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional water-splitting hydrogen boiler, comprising a furnace body and a heating platform located at the bottom of the furnace body, wherein an insulated water tank group consisting of an outer water tank and an inner water tank connected to each other is fixedly installed on the inner wall of the furnace body, and a steam chamber connected to the inner water tank is fixedly installed on the inner wall of the furnace body.

[0008] It also includes a partition tube fixedly installed inside the furnace, and a flow channel located on the heating table baking path is provided between the outer wall of the partition tube and the outer wall of the inner water tank and the steam chamber.

[0011] Preferably, the top of the furnace body is provided with an air outlet that connects to the partition pipe, and the inner diameter of the air outlet is smaller than the inner diameter of the partition pipe. The furnace body is provided with multiple gas inlet pipes, and the two ends of the gas inlet pipes are located below the air outlet and the partition pipe, respectively.

[0012] Preferably, a circular control frame is fixedly installed inside the furnace body between the partition tube and the heating table. The top of the circular control frame is provided with control slots arranged in a circular array, and a set of shielding plates arranged in a linear array are movably arranged in the control slots to make the exposed size of the control slot opening adjustable.

[0013] Preferably, the shielding plate assembly includes an exhaust box and first air passages symmetrically arranged on both sides of the exhaust box. The exhaust box is connected to an air inlet pipe, and the exhaust nozzle at the top of the exhaust box faces the first blade hinged in the first air passage.

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] As shown in Figures 1-12, a multifunctional water-splitting hydrogen boiler includes a furnace body 1 and a heating platform 31 located at the bottom of the furnace body 1. The inner wall of the furnace body 1 is fixedly installed with an insulated water tank group consisting of an outer water tank 14 and an inner water tank 15 that are interconnected. The inner wall of the furnace body 1 is also fixedly installed with a steam chamber 16 that is connected to the inner water tank 15.

[0035] It also includes a partition tube 2 fixedly installed inside the furnace body 1, and a flow channel 19 located on the baking path of the heating table 31 is provided between the outer wall of the partition tube 2 and the inner water tank 15 and the outer wall of the steam chamber 16. The partition tube 2 is provided with air ducts 21 arranged in a circular array and connected to the steam chamber 16 respectively, and the bottom end of the air ducts 21 is located above the heating table 31.

[0036] Specifically, multiple safety valves 17 are fixedly installed on the partition between the inner water tank 15 and the steam chamber 16. A first notch 22 is provided on the inner wall of the air duct 21, and a second notch 18 is provided on the inner wall of the steam chamber 16, which is connected to and matches the first notch 22. A water source pipe 11 is provided on the outer wall of the furnace body 1, which is connected to the outer water tank 14. Water is supplied to the outer water tank 14 through the water source pipe 11 connected to the external water source.

[0037] The heating platform 31 is equipped with a natural gas pipeline for injecting natural gas to react with high-temperature steam and ignite liquid alkanes or liquid aromatics. The combustion of the liquid alkanes or liquid aromatics generates heat, which in turn heats the outer wall of the partition pipe 2, the steam chamber 16, and one side of the outer wall of the inner water tank 15. This heat transfers heat from the outer wall of the inner water tank 15 to the water within it, causing steam to evaporate. When the steam pressure in the inner water tank 15 reaches the pressure value of the safety valve 17, steam is released from the inner water tank 15. Steam is injected into the steam chamber 16 along the safety valve 17. At this time, the outer wall of the steam chamber 16 is heated by the heating platform 31, thereby raising the temperature of the steam injected into the steam chamber 16. Then, the steam in the steam chamber 16 enters the gas duct 21 through the second notch 18 and the first notch 22. The heat of the outer wall of the partition tube 2 is transferred to the steam in the gas duct 21 by the heating platform 31, thereby further heating the steam in the gas duct 21. Then, the high-temperature steam reacts with the natural gas injected from the natural gas pipeline on the heating platform 31 to produce hydrogen.

[0038] By connecting and separating the outer water tank 14 and the inner water tank 15, when the heating platform 31 heats the inner water tank 15, the water in the inner water tank 15 can absorb heat first and then evaporate, so that it is not necessary to make the outer water tank 14 and the inner water tank 15 reach the boiling point at the same time, thereby quickly generating steam.

[0039] The outer water tank 14 and the inner water tank 15 are both made of stainless steel.

[0040] In the above technical solution, by using the outer water tank 14 and the inner water tank 15 to provide a water source, the furnace body 1 can be kept warm. When the heating platform 31 heats the outer wall of one side of the inner water tank 15, the water in the inner water tank 15 evaporates to generate steam. The steam then enters the steam chamber 16 and is sprayed upwards along multiple air intake channels 21. The steam is heated through the convection channel 19 of the heating platform 31, thereby raising the temperature of the steam in the steam chamber 16 and the air intake channel 21. The heat from heating the water in the inner water tank 15 by the heating platform 31 is used to reheat the high-temperature steam, so that the heat energy is utilized more fully. Compared with the traditional method of transporting high-temperature steam from outside the furnace body 1 to inside the furnace body 1, by using the water heated inside the furnace body 1 and using the heat energy of the heated water to reheat the steam, the steam temperature is increased while the water can also be used to keep the furnace body 1 warm.

[0041] As a further embodiment of the present invention, a vacuum insulation layer 8 is provided between the outer water tank 14 and the inner water tank 15.

[0042] Specifically, by utilizing the vacuum insulation layer 8 between the outer water tank 14 and the inner water tank 15, the contact area between the inner water tank 15 and the outer water tank 14 is reduced, and the inner water tank 15 can be kept warm. Thus, when the heat from the combustion on the heating platform 31 is used to heat the convection channel 19, the heat from the combustion is transferred to the outer wall of the inner water tank 15 and finally to the water in the inner water tank 15, so that the water is heated and evaporated to produce high-temperature steam. By utilizing the vacuum insulation layer 8 and the separation arrangement between the outer water tank 14 and the inner water tank 15, more of the heat received by the inner water tank 15 is applied to the water in the inner water tank 15, so that the water is heated rapidly in a short time to evaporate.

[0043] As another embodiment of the present invention, the inner wall of the partition tube 2 is located on the path of the flame generated by the combustion of the heating platform 31, and the partition tube 2 is provided with a plurality of through grooves 23 for communicating with each other between the flow channel 19 and the inner wall of the partition tube 2.

[0044] Specifically, as shown in Figures 2 and 7, through multiple slots 23 opened on the partition tube 2, when the liquid alkanes or liquid aromatics on the heating platform 31 are burned for heating, the flame and heat from the combustion flow to the flow channel 19 and the inner wall of the partition tube 2, respectively. Thus, the heat in the flow channel 19 heats the outer wall of the partition tube 2, as well as the outer wall of the steam chamber 16 and the inner water tank 15. This heating transfers the heat from the outer wall of the inner water tank 15 to the water inside the inner water tank 15. The heat in the flow channel 19 acts on the outer wall of the steam chamber 16, thus heating the steam in the steam chamber 16 in the first step. Simultaneously, the heat in the flow channel 19 acts on the outer wall of the partition tube 2, thus heating the steam in the air intake channel 21 in the second step. The heat absorbed by the inner wall of the partition tube 2 heats the steam in the air intake channel 21 in the third step. Through multiple heating steps, the steam can be heated to better facilitate the water-hydrogen decomposition reaction.

[0045] As another embodiment of the present invention, the top of the furnace body 1 is provided with an air outlet 13 connected to the partition pipe 2, and the inner diameter of the air outlet 13 is smaller than the inner diameter of the partition pipe 2. The furnace body 1 is provided with a plurality of gas inlet pipes 33, and the two ends of the gas inlet pipes 33 are respectively located below the air outlet 13 and the partition pipe 2.

[0046] Specifically, as shown in Figures 2 and 8, a gas transfer neck 12 is fixedly connected to the top of the partition tube 2 inside the furnace body 1, and the gas transfer neck 12 and the gas outlet 13 are interconnected. Since the inner diameter of the gas outlet 13 is smaller than the inner diameter of the partition tube 2, according to the Venturi effect, when the fluid passes through the narrowed flow cross section, the flow velocity will increase and the pressure will decrease. Since a baffle ring plate 7 is fixedly installed on the inner wall of the gas outlet 13, and the first end of the gas inlet pipe 33 is located on one side of the baffle ring plate 7, when expanding gas is generated in the furnace body 1, the gas flows faster along the gas outlet 13. At the same time, the baffle ring plate 7 partially intercepts the gas outlet 13, causing the rapidly flowing gas to flow into the gas inlet pipe 33. Then, guided by the gas inlet pipe 33, some of the hydrogen produced by water decomposition is transmitted through the first end of the gas inlet pipe 33 to the bottom of the partition pipe 2, so that the hydrogen can be used to burn again to release heat to participate in the reaction of water decomposition of hydrogen, thereby realizing the recycling of part of the energy.

[0047] As another embodiment of the present invention, a circular control frame 3 is fixedly installed inside the furnace body 1 between the partition tube 2 and the heating table 31. The top of the circular control frame 3 is provided with a control groove 32 arranged in a circular array, and a set of shielding plates arranged in a linear array is movably arranged in the control groove 32 to make the size of the exposed groove opening of the control groove 32 adjustable.

[0048] Specifically, it is known that hydrogen and oxygen are produced through high-temperature steam decomposition. The oxygen produced by high-temperature steam decomposition comes into contact with the liquid alkanes or liquid aromatics used for heating to maintain the combustion of the liquid alkanes or liquid aromatics. Since the circular control rack 3 is located above the heating platform 31, when the furnace body 1 first starts to react, the opening of the control tank 32 is exposed to the maximum extent, so that the heating platform 31 can burn more vigorously to heat the inner water tank 15. After the inner water tank 15 is heated and generates high-temperature steam, the high-temperature steam undergoes a water decomposition reaction to produce hydrogen. Then, the gas inlet pipe 33 is used to allow some of the hydrogen to flow back to the bottom of the partition pipe 2 for combustion. At this time, the baffle plate assembly can be used to reduce the exposed area of ​​the opening of the control tank 32, thereby reducing the contact between oxygen and the liquid alkanes or liquid aromatics on the heating platform 31, thus reducing the use of liquid alkanes or liquid aromatics and saving energy.

[0049] The shielding plate assembly can adjust the exposed area of ​​the opening of the control groove 32 by using multiple louvers in conjunction with connecting rods and electric push rods to rotate multiple louvers and adjust the exposed area of ​​the opening of the control groove 32; it can also be done by using multiple louvers in conjunction with connecting rods and manual adjustment; or any method known to those skilled in the art for adjusting the exposed surface of the opening of the control groove 32.

[0050] As the preferred embodiment provided by the present invention, the shielding plate assembly includes an exhaust box 4 and a first air passage 43 symmetrically arranged on both sides of the exhaust box 4. The exhaust box 4 is connected to the air inlet pipe 33, and the exhaust nozzle 41 opened on the top of the exhaust box 4 faces the first blade 6 hinged in the first air passage 43. The two first blades 6 flip their first ends to respectively shield the first air passage 43.

[0051] Specifically, an annular air pipe 34 is fixedly installed on the circular control frame 3, and the second end of the air inlet pipe 33 is fixedly connected to the annular air pipe 34. A support 35 is fixedly installed on the bottom of the circular control frame 3, located on one side of the control groove 32, and guide rods 36 are symmetrically arranged on the support 35. The two guide rods 36 are located below the control groove 32. Multiple exhaust boxes 4 are fixedly installed on the top of the two guide rods 36 and on the inner wall of the control groove 32, arranged in a linear array. The exhaust nozzles 41 opened on the top of the exhaust boxes 4 are connected to the annular air pipe 34 through the air passages in the guide rods 36 and the support 35. Vertical plates 37 are symmetrically fixedly installed on the top of the guide rods 36 on both sides of the exhaust boxes 4, and a first air passage 43 is formed between the two vertical plates 37 and the outer wall of the exhaust boxes 4. A first blade 6 is hinged to the inner wall of the control groove 32 and moves within the first air passage 43.

[0052] Furthermore, as shown in Figure 10, in the default state, the first ends of the two first blades 6 in the baffle assembly are attached to the vertical plate 37. At this time, the flame of the liquid alkane or liquid aromatic hydrocarbon burning on the heating platform 31 burns between the two first blades 6 and between the multiple baffle assemblies. Then, after heating the inner water tank 15 to generate steam, the steam decomposes water to produce hydrogen gas, which flows into the outlet pipe 13. Then, through the gas inlet pipe 33, the annular gas pipe 34, the support 35 and the guide rod 36, the hydrogen gas is ejected through the exhaust nozzle 41 opened on the top of the exhaust box 4. Due to the intense combustion of hydrogen gas, a strong impact force is generated, which impacts the two first blades 6, causing the two first blades 6 to flip. When the two first blades 6 flip, the first ends of the two first blades 6 detach from the vertical plate 37 and adhere to the outer wall of the exhaust box 4, thereby shielding the first gas passage 43. At this time, the first gas passage 43 is blocked, thereby reducing the contact between oxygen and the liquid alkanes or liquid aromatics burning on the heating platform 31, thus saving the use of combustion energy.

[0053] As another embodiment of the present invention, a second air passage 42 is provided between every two baffle plate groups, and the first blade 6 is flipped so that its second end covers the second air passage 42.

[0054] Specifically, as shown in Figures 6 and 9, a second air passage 42 is provided between two adjacent baffle groups, and the second ends of the two first blades 6 near the second air passage 42 are respectively movable above the second air passage 42.

[0055] Furthermore, when the inner water tank 15 is heated to generate steam, the steam decomposes water to produce hydrogen gas, which then flows into the outlet pipe 13. The hydrogen gas is then ejected through the exhaust nozzle 41 at the top of the exhaust box 4 via the inlet pipe 33, the annular pipe 34, the support 35, and the guide rod 36. At this time, the intense combustion of hydrogen gas generates a strong impact force, which impacts the two first blades 6, causing them to flip. When the two first blades 6 flip, their first ends detach from the vertical plate 37 and adhere to the outer wall of the exhaust box 4, thereby shielding the first air passage 43. At the same time, the second ends of the first blades 6 flip over and are positioned above the second air passage 42, thus shielding the area above the second air passage 42. Therefore, by using the first end of the first blade 6 to shield the first air passage 43, and the second end of the first blade 6 to shield the upper part of the second air passage 42, the contact between the oxygen produced by water vapor decomposition and the liquid alkanes or liquid aromatics burning on the heating platform 31 is reduced, thereby further saving the use of combustion energy.

[0056] As another embodiment of the present invention, a plurality of guide plates 5 are rotatably arranged above the opening of the regulating groove 32, and the top of the guide plate 5 is tilted towards the flow channel 19 in the default state, and the guide plate 5 swings so that its top is towards the inner wall of the partition tube 2.

[0057] Specifically, as shown in Figures 3 and 5, the top of the circular control frame 3 is symmetrically provided with fixed plates 38 on both sides of the opening of the control groove 32, and multiple guide plates 5 are arranged in a linear array between the two fixed plates 38 and hinged on the two fixed plates 38.

[0058] Furthermore, when the water-hydrogen decomposition reaction begins in the furnace body 1, the guide plate 5 is in the default state, with its top tip tilted towards the flow channel 19. At this time, the liquid alkanes or liquid aromatics burning on the heating platform 31, under the guidance of the tilted state of the guide plate 5, have more heat flowing into the flow channel 19. When the heat in the flow channel 19 heats the outer wall of the inner water tank 15, the water in the inner water tank 15 evaporates to produce steam. The steam then enters the steam chamber 16 and is sprayed upwards along multiple air intake channels 21 onto the heating platform 31. The heating platform 31 heats the flow channel 19, thereby raising the temperature of the steam in the steam chamber 16 and the air intake channels 21. At the same time, some of the heat from the combustion on the heating platform 31 flows into the partition tube 2, thereby heating the inner wall of the partition tube 2, further raising the temperature of the steam in the air intake channels 21. By using multiple guide plates 5 tilted towards the flow channel 19 in the default state, more of the heat from the liquid alkanes or liquid aromatics heated on the heating platform 31 can be used to heat the water in the inner water tank 15, thereby rapidly raising the temperature to generate steam for the water-hydrogen decomposition reaction, thus making reasonable use of the heat.

[0059] Then, after high-temperature steam begins to be ejected from the air intake channel 21, multiple guide plates 5 are driven to swing so that their tops face the inner wall of the partition tube 2. At this time, more of the combustion heat on the heating platform 31 enters the partition tube 2 to participate in the reaction of water decomposition of hydrogen, thereby accelerating the reaction of water decomposition of hydrogen and making reasonable use of the combustion heat on the heating platform 31.

[0060] The multiple guide plates 5 can swing in any way, such as by using an electric push rod in conjunction with a connecting rod; or by using a motor in conjunction with gears, racks and pinions; or by any method known to those skilled in the art to drive the multiple guide plates 5 to swing.

[0061] As another embodiment of the present invention, the bottom end of the guide plate 5 is located on the swing path of the second end of the first leaf plate 6, and the torsion spring 51 provided on the guide plate 5 is deformed and stores force when the guide plate 5 swings.

[0062] Specifically, as shown in Figure 10, the two ends of the torsion spring 51 sleeved on the hinge shaft of the guide plate 5 are fixedly installed on the guide plate 5 and the fixed plate 38 respectively. In the default state, the torsion spring 51 drives the bottom end of the guide plate 5 to push the second end of the first blade 6, thereby making the first end of the first blade 6 fit against the vertical plate 37. At the same time, the top end of the guide plate 5 is kept tilted towards the flow channel 19 to be in the default state.

[0063] Therefore, when the water-hydrogen decomposition reaction begins inside the furnace body 1, the guide plate 5 is in its default state, with its top tip tilted towards the flow channel 19. At this time, the heat from the liquid alkanes or liquid aromatics burning on the heating platform 31 flows out through the second air passage 42, and under the guidance of the tilted guide plate 5, more heat flows into the flow channel 19. Simultaneously, because the first end of the first blade 6 is attached to the vertical plate 37, the first air passage 43 is opened. This allows external air to come into contact with the liquid alkanes or liquid aromatics burning on the heating platform 31, enhancing the combustion effect. Heat can also be discharged through the first air passage 43. When the heat from the flow channel 19 heats the outer wall of the inner water tank 15, the water in the inner water tank 15 evaporates to produce steam. This steam then enters the steam chamber 16 and is sprayed upwards onto the heating platform 31 along multiple air intake channels 21. The heating platform 31 heats the flow channel 19, thereby raising the temperature of the steam in the steam chamber 16 and the air intake channels 21. Simultaneously, some of the heat from the combustion on the heating platform 31 flows into the partition tube 2, further heating the inner wall of the partition tube 2 and thus further raising the temperature of the steam in the air intake channels 21. By using multiple guide plates 5 tilted towards the flow channel 19 in their default state, more of the heat from the liquid alkanes or liquid aromatics heated on the heating platform 31 can be used to heat the water in the inner water tank 15, rapidly raising the temperature to produce steam for the water-hydrogen decomposition reaction, thus making efficient use of heat.

[0064] Then, after high-temperature steam begins to be ejected from multiple air intake channels 21, the high-temperature steam begins to decompose water into hydrogen. The hydrogen produced then flows into the outlet 13, and then through the inlet pipe 33, the annular pipe 34, the support 35 and the guide rod 36, the hydrogen is ejected through the exhaust nozzle 41 opened at the top of the exhaust box 4. At this time, due to the intense combustion of hydrogen, a strong impact force is generated, which impacts the two first blades 6, causing the two first blades 6 to flip. When the two first blades 6 flip, the first ends of the two first blades 6 detach from the vertical plate 37 and adhere to the outer wall of the exhaust box 4, thereby shielding the first air passage 43. At the same time, the second ends of the first blades 6 flip over above the second air passage 42, thereby shielding the upper part of the second air passage 42 to a certain extent. Therefore, by using the first end of the first blade 6 to shield the first air passage 43, and the second end of the first blade 6 to shield the upper part of the second air passage 42, the contact between the oxygen produced by water vapor decomposition and the liquid alkanes or liquid aromatics burning on the heating platform 31 is reduced, thereby further saving the use of combustion energy.

[0065] Furthermore, as shown in Figure 9, with the first blade 6 of the baffle plate assembly flipped, the second end of one of the first blades 6 pushes against the bottom end of the guide plate 5, thereby driving the top end of the guide plate 5 to flip towards the inner wall of the partition tube 2. Simultaneously, the torsion spring 51 deforms and stores energy due to the flipping of the guide plate 5. As shown in Figure 9, with the second end of the first blade 6 and the guide plate 5 tilted, the heat flowing through the second air passage 42 is guided into the partition tube 2. Simultaneously, the heat generated after the hydrogen gas from the exhaust nozzle 41 burns is partially guided by the guide plate 5 to flow into the partition tube 2. This allows more heat to enter the partition tube 2 for a more concentrated and thorough reaction of water splitting into hydrogen. Therefore, during the production and recycling of hydrogen, the strong impact force generated by the intense combustion of hydrogen drives the first blade 6 to flip, thereby adjusting the direction of heat flow. This improves the start-up efficiency of steam generation from water evaporation and the heat required for subsequent water splitting into hydrogen, thus rationally utilizing heat within a relatively low energy and heat constraints.

[0066] As a further preferred embodiment of the present invention, when the top of the guide plate 5 faces the inner wall of the partition tube 2, the high-temperature steam ejected from the air duct 21 is located on the path of the airflow on the guide plate 5.

[0067] Specifically, when the water-to-hydrogen reaction begins inside the furnace body 1, the guide plate 5 is in its default state, with its top tip tilted towards the flow channel 19. At this time, the heat from the liquid alkanes or aromatics burning on the heating platform 31 flows out through the second gas passage 42, and guided by the tilted state of the guide plate 5, more heat flows into the flow channel 19. Simultaneously, because the first end of the first blade 6 is attached to the vertical plate 37, the first gas passage 43 is opened. This open passage allows external air to come into contact with the liquid alkanes or aromatics burning on the heating platform 31, enhancing the combustion effect. Heat can also be discharged through the first gas passage 43. When the heat from the flow channel 19 heats the outer wall of the inner water tank 15, the water in the inner water tank 15 evaporates to produce steam. This steam then enters the steam chamber 16 and is sprayed upwards onto the heating platform 31 along multiple air intake channels 21. The heating platform 31 heats the flow channel 19, thereby raising the temperature of the steam in the steam chamber 16 and the air intake channels 21. Simultaneously, some of the heat from the combustion on the heating platform 31 flows into the partition tube 2, further heating the inner wall of the partition tube 2 and thus further raising the temperature of the steam in the air intake channels 21. By using multiple guide plates 5 tilted towards the flow channel 19 in their default state, more of the heat from the liquid alkanes or liquid aromatics heated on the heating platform 31 can be used to heat the water in the inner water tank 15, rapidly raising the temperature to produce steam for the water-hydrogen decomposition reaction, thus making efficient use of heat.

[0068] Then, after high-temperature steam begins to be ejected from multiple air intake channels 21, the high-temperature steam begins to decompose water into hydrogen. The hydrogen produced then flows into the outlet 13, and then through the inlet pipe 33, the annular pipe 34, the support 35 and the guide rod 36, the hydrogen is ejected through the exhaust nozzle 41 opened at the top of the exhaust box 4. At this time, due to the intense combustion of hydrogen, a strong impact force is generated, which impacts the two first blades 6, causing the two first blades 6 to flip. When the two first blades 6 flip, the first ends of the two first blades 6 detach from the vertical plate 37 and adhere to the outer wall of the exhaust box 4, thereby shielding the first air passage 43. At the same time, the second ends of the first blades 6 flip over above the second air passage 42, thereby shielding the upper part of the second air passage 42 to a certain extent. Therefore, by using the first end of the first blade 6 to shield the first air passage 43, and the second end of the first blade 6 to shield the upper part of the second air passage 42, the contact between the oxygen produced by water vapor decomposition and the liquid alkanes or liquid aromatics burning on the heating platform 31 is reduced, thereby further saving the use of combustion energy.

[0069] Furthermore, as shown in Figure 9, with the first blade 6 of the baffle plate assembly flipped, the second end of one of the first blades 6 pushes against the bottom end of the guide plate 5, thereby driving the top end of the guide plate 5 to flip towards the inner wall of the partition tube 2. Simultaneously, the torsion spring 51 deforms and stores energy due to the flipping of the guide plate 5. As shown in Figure 9, with the second end of the first blade 6 and the guide plate 5 tilted, the heat flowing through the second air passage 42 is guided into the partition tube 2. Simultaneously, the heat generated after the hydrogen gas emitted from the exhaust nozzle 41 is partially guided by the guide plate 5 to flow into the partition tube 2. This allows more heat to enter the partition tube 2 for a more concentrated and thorough reaction of water splitting into hydrogen. Therefore, during the production and recycling of hydrogen, the strong impact force generated by the intense combustion of hydrogen drives the first blade 6 to flip, thereby adjusting the direction of heat flow and making rational use of heat.

[0070] Furthermore, as shown by the arrows in Figure 12, the heat flowing through the second gas passage 42 is guided into the partition tube 2 along the second end of the first blade 6 and the inclined state of the guide plate 5. Simultaneously, the heat generated by the combustion of hydrogen from the exhaust nozzle 41 flows into the partition tube 2 under the partial guidance of the guide plate 5. The exhaust port at the bottom of the intake duct 21 is located above the circular control frame 3. At this time, the heat flowing from the second gas passage 42 and the exhaust nozzle 41 is guided towards the partition tube 2 by the guide plate 5 and the first blade 6. According to Bernoulli's principle, the greater the flow velocity, the lower the pressure. The high-temperature steam discharged at the bottom of the intake duct 21 flows along with the heat towards the partition tube 2, thus guiding the high-temperature steam into the partition tube 2 for better water splitting of hydrogen.

[0071] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
