Description

Technical Field

[0001] The invention relates to the technical field of water decomposition hydrogen production, and in particular to a multifunctional water decomposition hydrogen boiler. Background Art

[0002] The production of hydrogen is widely used in the fields of industry, laboratory, energy and environment. At present, the production of hydrogen can be divided into several types: electrolysis, which decomposes water into hydrogen and oxygen through the action of electric current; high-temperature steam hydrogen production, which produces hydrogen by reacting natural gas or other hydrocarbon compounds with water vapor; chemical hydrogen production, etc.

[0003] According to patent No. CN211255243U, the publication (announcement) date: 2020-08-14 discloses a water decomposition hydrogen boiler, wherein a cylindrical two-stage steam filter connected to the boiler steam is arranged at the upper part of the boiler furnace, a high-temperature combustion-supporting reaction combustion pile is arranged at the lower part of the furnace, and a coil-shaped steam decomposition hydrogen generator is half buried on the inner middle and upper surface of the combustion pile, and a steam connecting pipe with a loose bottom and a tight top is arranged in the upper middle of the hydrogen generator, and one end of the steam connecting pipe passes through the internal structure in the middle of the furnace from bottom to top and rises to the upper part and is connected and docked with the upper part of the steam filter arranged at the upper part of the furnace, and a hydrogen output pipe is arranged in the lower middle of the hydrogen generator to pass through the outside of the lower part of the furnace, and a gas distribution pipe is arranged at the outlet of the output pipe, and one end of the gas distribution pipe returns to the furnace and enters the lower middle of the combustion pile.

[0004] In the prior art including the above patents, it uses high-temperature steam at a high temperature of more than 950 ° C to decompose and produce hydrogen, and it uses part of the produced hydrogen to realize circulation, thereby saving energy. At present, high-temperature steam needs to be heated by water to produce steam, and then the gas pressure of high-temperature steam is increased and discharged into the boiler to decompose hydrogen by water. In the method of using external heating water to make steam and pass the pipeline to the boiler, the heat of high-temperature steam will be lost when passing through the pipeline. At the same time, because the steam is in a high-pressure state in the pipeline, the pressure of steam is reduced when it is released into the boiler along the pipeline. It is known that when the high-pressure gas is converted into a low-pressure gas, this process is usually accompanied by the volume expansion of the gas, and the gas does work externally during the expansion process, resulting in a decrease in its internal energy and a decrease in temperature. Due to the decrease in the 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 pipeline. However, increasing the temperature of the high-temperature steam also increases the cost of producing hydrogen. Summary of the invention

[0020] In order 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.

[0021] like Figure 1-12 As shown, a multifunctional water decomposition hydrogen boiler comprises a furnace body 1 and a heating platform 31 located at the inner bottom thereof, a heat preservation water tank group consisting of an outer water tank 14 and an inner water tank 15 connected to each other is fixedly installed on the inner wall of the furnace body 1, and a steam chamber 16 connected to the inner water tank 15 is fixedly installed on the inner wall of the furnace body 1; It also includes a barrier tube 2 fixedly installed in the furnace body 1, and a flow channel 19 located on the baking path of the heating platform 31 is arranged between the outer wall of the barrier tube 2 and the outer wall of one side of the inner water tank 15 and the steam chamber 16, and air ducts 21 arranged in a circular array and respectively connected to the steam chamber 16 are arranged in the barrier tube 2, and the bottom ends of the air ducts 21 are located above the heating platform 31.

[0022] Specifically, a plurality of safety valves 17 are fixedly installed on the adjacent partitions 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 which is interconnected with and matched with the first notch 22 is provided on the inner wall of the steam chamber 16, and a water source pipe 11 which is connected to the outer water tank 14 is provided on the outer wall of the furnace body 1, and water is supplied to the outer water tank 14 by connecting the water source pipe 11 through an external water source.

[0023] The heating table 31 is provided with a natural gas pipeline for burning and heating liquid alkanes or liquid aromatic hydrocarbons and reacting with high-temperature steam to inject natural gas. By burning the liquid alkanes or liquid aromatic hydrocarbons to generate heat, the flame and the heat of the flame heat the outer wall of the interlayer tube 2 and the outer wall of the steam chamber 16 and one side of the inner water tank 15, so that the heat of the outer wall of the inner water tank 15 is transferred to the water in the inner water tank 15 by heating, so that steam is generated by evaporation of the water in the inner water tank 15. Then, when the steam pressure in the inner water tank 15 reaches the pressure value of the safety valve 17, the inner water tank 15 is The steam is sprayed into the steam chamber 16 along the safety valve 17. At this time, the outer wall of one side of the steam chamber 16 is heated by the heating platform 31, so that the steam sprayed into the steam chamber 16 is heated to a certain extent, and then the steam in the steam chamber 16 enters the air duct 21 along the second notch 18 and the first notch 22, so that the outer wall of the interlayer tube 2 is heated by the heating platform 31 so that the heat of the interlayer tube 2 is transferred to the steam in the air duct 21, thereby further heating the steam in the air duct 21, and then the high-temperature steam reacts with the natural gas sprayed from the natural gas pipeline on the heating platform 31 to generate hydrogen.

[0024] By connecting and separating the outer water tank 14 and the inner water tank 15, when the heating table 31 heats the inner water tank 15, the water in the inner water tank 15 can first absorb heat and then evaporate, so there is no need to make the outer water tank 14 and the inner water tank 15 reach boiling point at the same time, thereby quickly generating steam.

[0025] The outer water tank 14 and the inner water tank 15 are respectively stainless steel boxes.

[0026] In the above technical scheme, the outer water tank 14 and the inner water tank 15 are used to provide a water source, and 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, and then the steam enters the steam chamber 16 and is sprayed to the top of the heating platform 31 along multiple air ducts 21. The convection channel 19 is heated by the heating platform 31, so that the steam in the steam chamber 16 and the air duct 21 is heated, and the heat of the water in the inner water tank 15 heated by the heating platform 31 is used to heat the high-temperature steam for a second time, so that the thermal energy is more fully utilized. Compared with the traditional high-temperature steam transported from the outside of the furnace body 1 to the furnace body 1, the water is heated in the furnace body 1, and the heat energy of the heated water is used to heat the steam for a second time, so as to increase the steam temperature and keep the furnace body 1 warm by using the water.

[0027] As an embodiment further provided by the present invention, a vacuum insulation layer 8 is provided between the outer water tank 14 and the inner water tank 15 .

[0028] 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 a certain insulation effect can be achieved for the inner water tank 15, so that when the heat from the combustion on the heating table 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 body in the inner water tank 15, so that the water body is heated and evaporated to produce high-temperature steam. By utilizing the vacuum insulation layer 8 and the separation between the outer water tank 14 and the inner water tank 15, the heat received by the inner water tank 15 acts more on the water body in the inner water tank 15, so that the water body is quickly heated and evaporated in a short time.

[0029] As another embodiment provided by the present invention, the inner wall of the barrier tube 2 is located on the path of the flame generated by the combustion of the heating platform 31, and the barrier tube 2 is provided with a plurality of through grooves 23 for interconnecting the flow channel 19 and the inner wall of the barrier tube 2.

[0030] Specifically, Figure 2 and Figure 7As shown, through the multiple grooves 23 opened on the interlayer tube 2, when the liquid alkane or liquid aromatic hydrocarbon on the heating platform 31 is burned and heated, the burning flame and heat flow to the flow channel 19 and the inner wall of the interlayer tube 2 respectively, so that the heat in the flow channel 19 is used to heat the outer wall of the interlayer tube 2 and the outer wall of the steam chamber 16 and one side of the inner water tank 15, so that the heat of the outer wall of the inner water tank 15 is transferred to the water in the inner water tank 15 through heating, and the heat in the flow channel 19 acts on the outer wall of the steam chamber 16, so that the steam in the steam chamber 16 is heated in the first step, and at the same time, the heat in the flow channel 19 acts on the outer wall of the interlayer tube 2, and then the steam in the air duct 21 is heated in the second step, and the heat absorbed by the inner wall of the interlayer tube 2 is used to heat the steam in the air duct 21 in the third step, and then the steam is heated through multiple steps, so as to better carry out the reaction of water decomposition and hydrogen.

[0031] As another embodiment provided by the present invention, a gas outlet port 13 connected to the barrier tube 2 is provided on the top of the furnace body 1, and the inner diameter of the gas outlet port 13 is smaller than the inner diameter of the barrier tube 2, and a plurality of gas connecting pipes 33 are provided on the furnace body 1, and the two ends of the gas connecting pipes 33 are respectively located below the gas outlet port 13 and the barrier tube 2.

[0032] Specifically, Figure 2 and Figure 8 As shown, a gas-turning neck 12 is fixedly connected to the top of the interlayer tube 2 in the furnace body 1, and the gas-turning neck 12 and the gas outlet 13 are connected to each other. Since the inner diameter of the gas outlet 13 is smaller than the inner diameter of the interlayer tube 2, it can be seen from the Venturi effect that when the fluid passes through the reduced flow section, the flow rate will increase, and the pressure will decrease. Since a shielding ring plate 7 is fixedly installed on the inner wall of the gas outlet 13, and the first end of the gas connection pipe 33 is located on one side of the shielding ring plate 7, when the expanded gas is generated in the furnace body 1, the gas flows along the gas outlet 13 faster, and at the same time, the shielding ring plate 7 partially intercepts the gas outlet 13 so that part of the fast-flowing air flows into the gas connection pipe 33 respectively, and then the part of the hydrogen generated by water decomposition is guided by the gas connection pipe 33 so that part of the hydrogen is transmitted to the bottom of the interlayer tube 2 through the first end of the gas connection pipe 33, so that the hydrogen is used to burn again to release heat to participate in the reaction of water decomposition and hydrogen, thereby realizing the recycling of part of the energy.

[0033] As another embodiment provided by the present invention, a circular regulating frame 3 is fixedly installed in the furnace body 1 and is located between the interlayer tube 2 and the heating platform 31. The top of the circular regulating frame 3 is provided with regulating grooves 32 arranged in a circular array, and a baffle plate group arranged in a linear array is movably provided in the regulating groove 32 and is used to make the exposed size of the notch of the regulating groove 32 adjustable.

[0034] Specifically, it is known that hydrogen and oxygen are generated by decomposition of high-temperature steam, and the oxygen generated by decomposition of high-temperature steam contacts the liquid alkane or liquid aromatic hydrocarbon used for heating to maintain the combustion of the liquid alkane or liquid aromatic hydrocarbon. Since the circular regulating frame 3 is located above the heating platform 31, when the furnace body 1 just starts to react, the notch of the regulating groove 32 is exposed to the maximum, so that the heating platform 31 can burn more violently to heat the inner water tank 15, and then when the inner water tank 15 is heated to generate high-temperature steam, the high-temperature steam performs a water decomposition reaction to generate hydrogen, and then the gas connection pipe 33 is used to make part of the hydrogen flow back to the bottom of the interlayer tube 2 for combustion. At this time, the shielding plate group can be used to reduce the exposed area of ​​the notch of the regulating groove 32, thereby reducing the contact between oxygen and the liquid alkane or liquid aromatic hydrocarbon on the heating platform 31, thereby reducing the use of liquid alkane or liquid aromatic hydrocarbon to save energy.

[0035] The shielding plate group may adjust the exposed area of ​​the notch of the regulating groove 32 by using a plurality of louvers in cooperation with a connecting rod and an electric push rod to flip the plurality of louvers to adjust the exposed area of ​​the notch of the regulating groove 32; or it may be manually adjusted by using a plurality of louvers in cooperation with a connecting rod; or it may be any method known to those skilled in the art to adjust the exposed surface of the notch of the regulating groove 32.

[0036] As the optimal embodiment provided by the present invention, the baffle plate group includes an exhaust box 4 and a first air duct 43 symmetrically arranged on both sides of the exhaust box 4, the exhaust box 4 is connected to the air connecting pipe 33, and the exhaust nozzle 41 opened on the top of the exhaust box 4 faces the first blade 6 hingedly arranged in the first air duct 43, and the two first blades 6 flip their first ends to respectively shield the first air duct 43.

[0037] Specifically, an annular air pipe 34 is fixedly mounted on the circular regulating frame 3, and the second ends of the air pipes 33 are respectively fixedly connected to the annular air pipe 34. A bracket 35 is fixedly mounted on the bottom of the circular regulating frame 3 on one side of the regulating groove 32, and an air guide rod 36 is symmetrically arranged on the bracket 35. The two air guide rods 36 are respectively located below the regulating groove 32. A plurality of exhaust boxes 4 are respectively fixedly mounted on the tops of the two air guide rods 36 and on the inner wall of the regulating groove 32 and arranged in a linear array. The exhaust nozzles 41 opened on the tops of the exhaust boxes 4 are connected to the annular air pipe 34 through the air guide rods 36 and the air passages in the brackets 35. Vertical plates 37 are symmetrically fixedly mounted on the tops of the air guide rods 36 on both sides of the exhaust box 4, and a first air passage 43 is formed between the two vertical plates 37 and the outer wall of the exhaust box 4. The first blade 6 is hingedly arranged on the inner wall of the regulating groove 32 and moves in the first air passage 43.

[0038] Further, such as Fig.10As shown, in the default state, the first ends of the two first blades 6 in the shielding plate group 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 shielding plate groups. Then, after the inner water tank 15 is heated to generate steam, the steam decomposes water to generate hydrogen and flows into the air outlet 13, and then passes through the air connecting pipe 33, the annular air pipe 34, the support 35 and the air guide rod 36 to allow the hydrogen to be ejected through the exhaust nozzle 41 opened on the top of the exhaust box 4. Since the hydrogen burns violently, a strong impact force will be generated through its impact force to impact the two first blades 6, thereby causing the two first blades 6 to flip over. When the two first blades 6 flip over, the first ends of the two first blades 6 detach from the vertical plate 37 and fit against the outer wall of the exhaust box 4, thereby shielding the first air duct 43. At this time, the first air duct 43 is blocked, thereby reducing the contact between oxygen and the liquid alkanes or liquid aromatic hydrocarbons burning on the heating table 31, thereby saving the use of combustion energy.

[0039] As another embodiment provided by the present invention, a second air passage 42 is provided between every two shielding plate groups, and the first blade 6 is turned over so that the second end thereof shields the second air passage 42 .

[0040] Specifically, Figure 6 and Fig. 9 As shown, a second air passage 42 is disposed between two adjacent shielding plate groups, and the second ends of the two first blades 6 close to the second air passage 42 are respectively movable above the second air passage 42 .

[0041] Furthermore, when the inner water tank 15 is heated to generate steam, the steam decomposes water to generate hydrogen and then flows into the air outlet 13, and then passes through the air connecting pipe 33, the annular air pipe 34, the support 35 and the air guide rod 36 to allow the hydrogen to be ejected through the exhaust nozzle 41 opened on the top of the exhaust box 4. At this time, due to the fierce combustion of hydrogen, a strong impact force will be generated, which will impact the two first blades 6 through its impact force, thereby causing the two first blades 6 to flip over. When the two first blades 6 flip over, the first ends of the two first blades 6 detach from the vertical plate 37 and fit onto the outer wall of the exhaust box 4, thereby shielding the first air duct 43. At the same time, the second ends of the first blades 6 are respectively flipped over the second air duct 42, thereby shielding the top of the second air duct 42 to a certain extent. Therefore, the first end of the first blade 6 is used to shield the first air passage 43; the second end of the first blade 6 blocks the upper part of the second air passage 42 to a certain extent, thereby reducing the contact between the oxygen generated by the decomposition of water vapor and the liquid alkanes or liquid aromatic hydrocarbons burning on the heating table 31, thereby further saving the use of combustion energy.

[0042] As another embodiment provided by the present invention, a plurality of guide plates 5 are rotatably arranged above the slot of the regulating slot 32 , and the top of the guide plate 5 is tilted toward the flow channel 19 in the default state, and the guide plate 5 swings so that its top is toward the inner wall of the interlayer tube 2 .

[0043] Specifically, Figure 3 and Figure 5 As shown, the top of the circular regulating frame 3 is symmetrically provided with fixing plates 38 on both sides of the regulating slot 32 , and a plurality of guide plates 5 are respectively arranged in a linear array between the two fixing plates 38 and hingedly provided on the two fixing plates 38 .

[0044] Furthermore, when the water decomposition hydrogen reaction begins in the furnace body 1, the guide plate 5 is in a default state, and the top of the guide plate 5 is inclined toward the side of the flow channel 19. At this time, the liquid alkane or liquid aromatic hydrocarbon burned on the heating table 31 for heating is guided by the inclined state of the guide plate 5, and more heat flows into the flow channel 19. At this time, when the heat in the flow channel 19 is used to heat the outer wall of the inner water tank 15, the water in the inner water tank 15 evaporates to produce steam, and then the steam enters the steam chamber 16 and is sprayed toward the top of the heating table 31 along multiple air ducts 21. The heating table 31 heats the flow channel 19, thereby heating the steam in the steam chamber 16 and the air duct 21. At the same time, part of the heat burned on the heating table 31 flows into the interlayer tube 2, and then heats the inner wall of the interlayer tube 2, thereby further heating the steam in the air duct 21. By utilizing multiple guide plates 5 to tilt toward one side of the flow channel 19 in the default state, the heat of the liquid alkane or liquid aromatic hydrocarbon heated on the heating table 31 can be more used to heat the water in the inner water tank 15, thereby quickly heating up to generate steam for water decomposition and hydrogen reaction, so that the heat is reasonably utilized.

[0045] After the air duct 21 starts to spray high-temperature steam, the multiple guide plates 5 are driven to swing so that their top ends are directed toward the inner wall of the interlayer tube 2. At this time, more heat from the combustion on the heating table 31 enters the interlayer tube 2 to participate in the reaction of water decomposition into hydrogen, thereby accelerating the reaction of water decomposition into hydrogen and reasonably utilizing the heat from the combustion on the heating table 31.

[0046] The multiple guide plates 5 may be swung by an electric push rod in conjunction with a connecting rod; or by a motor in conjunction with a gear, a rack and a connecting rod; or by any other method known to those skilled in the art to drive the multiple guide plates 5 to swing.

[0047] As another embodiment further provided by the present invention, the bottom end of the guide plate 5 is located on the swinging path of the second end of the first blade 6, and the torsion spring 51 provided on the guide plate 5 is deformed to store force when the guide plate 5 swings.

[0048] Specifically, Fig.10 As shown, the two ends of the torsion spring member 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 member 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 on the vertical plate 37. At the same time, the top end of the guide plate 5 remains inclined toward the side of the flow channel 19 to be in the default state.

[0049] Therefore, when the water decomposition hydrogen reaction starts in the furnace body 1, the guide plate 5 is in the default state, and the top of the guide plate 5 is inclined toward the flow channel 19. At this time, the heat of the liquid alkane or liquid aromatic hydrocarbon burned on the heating table 31 for heating flows out through the second air passage 42, and under the guidance of the inclined state of the guide plate 5, more heat flows into the flow channel 19. At the same time, because the first end of the first blade 6 is attached to the vertical plate 37, the first air passage 43 is opened at this time, so that the opened first air passage 43 is used to make the external air contact with the liquid alkane or liquid aromatic hydrocarbon burned on the heating table 31 along the first air passage 43 to enhance its combustion effect. At the same time, the heat can also be discharged through the first air passage 43. At this time, when the heat in the flow channel 19 is used to heat the outer wall of the inner water tank 15, the water in the inner water tank 15 evaporates to generate steam, and then the steam enters the steam chamber 16, and is sprayed along the multiple air inlet channels 21 to the top of the heating platform 31, and the heating platform 31 heats the flow channel 19, thereby heating the steam in the steam chamber 16 and the air inlet channel 21, and at the same time, part of the heat burned on the heating platform 31 flows into the interlayer tube 2, and then heats the inner wall of the interlayer tube 2, thereby further heating the steam in the air inlet channel 21. By using multiple guide plates 5 to tilt toward one side of the flow channel 19 in the default state, the heat of the liquid alkane or liquid aromatic hydrocarbon used for heating on the heating platform 31 can be used more for heating the water in the inner water tank 15, so as to quickly heat up and generate steam for water decomposition hydrogen reaction, so that the heat is reasonably used.

[0050] Then, after the multiple air ducts 21 begin to spray high-temperature steam, the high-temperature steam begins to undergo a water-hydrogen decomposition reaction, and the produced hydrogen flows into the air outlet 13, and then passes through the air connecting pipe 33, the annular air pipe 34, the support 35 and the air guide rod 36 to allow the hydrogen to be sprayed out through the exhaust nozzle 41 opened on the top of the exhaust box 4. At this time, due to the fierce combustion of hydrogen, a strong impact force will be generated, which will impact the two first blades 6 through its impact force, thereby causing the two first blades 6 to flip over. When the two first blades 6 flip over, the first ends of the two first blades 6 detach from the vertical plate 37 and fit onto 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 are respectively flipped over the second air passage 42, thereby shielding the top of the second air passage 42 to a certain extent. Therefore, the first end of the first blade 6 is used to shield the first air passage 43; the second end of the first blade 6 blocks the upper part of the second air passage 42 to a certain extent, thereby reducing the contact between the oxygen generated by the decomposition of water vapor and the liquid alkanes or liquid aromatic hydrocarbons burning on the heating table 31, thereby further saving the use of combustion energy.

[0051] Furthermore, when one of the first blades 6 of the shielding plate group is turned over, Fig. 9 As shown, at this time, the second end of one of the first blades 6 pushes the bottom end of the guide plate 5, thereby driving the top end of the guide plate 5 to flip toward the inner wall of the interlayer tube 2. At the same time, the torsion spring 51 is deformed and stores force due to the flipping of the guide plate 5. Fig. 9 As shown, the second end of the first blade 6 and the guide plate 5 are tilted to guide the heat flowing through the second air passage 42 to flow into the interlayer tube 2, and at the same time, the heat generated by the combustion of the hydrogen ejected from the exhaust nozzle 41 flows into the interlayer tube 2 under the partial guidance of the guide plate 5, so that more heat enters the interlayer tube 2 to more concentratedly and fully carry out the reaction of water decomposition and hydrogen. Therefore, during the production and recycling of hydrogen, the strong impact force generated by the violent combustion of hydrogen is used to drive the first blade 6 to flip, so as to adjust the flow direction of heat, so as to improve the start-up efficiency of water evaporation to generate steam and the heat required for the subsequent water decomposition and hydrogen according to needs, so as to reasonably use heat in the case of relative energy and heat.

[0052] As a further optimal embodiment of the present invention, when the top end of the guide plate 5 faces the inner wall of the barrier tube 2 , the high-temperature steam ejected from the air duct 21 is located on the path of the air flow on the guide plate 5 .

[0053] Specifically, when the water decomposition hydrogen reaction begins in the furnace body 1, the guide plate 5 is in the default state, and the top of the guide plate 5 is tilted toward the flow channel 19. At this time, the heat of the liquid alkane or liquid aromatic hydrocarbon burned on the heating table 31 for heating flows out through the second air passage 42, and under the guidance of the inclined state of the guide plate 5, more heat flows into the flow channel 19. At the same time, because the first end of the first blade 6 is attached to the vertical plate 37, the first air passage 43 is opened at this time, so that the opened first air passage 43 is used to make the external air contact with the liquid alkane or liquid aromatic hydrocarbon burned on the heating table 31 along the first air passage 43 to enhance its combustion effect. At the same time, the heat can also be discharged through the first air passage 43. At this time, when the heat in the flow channel 19 is used to heat the outer wall of the inner water tank 15, the water in the inner water tank 15 evaporates to generate steam, and then the steam enters the steam chamber 16, and is sprayed along the multiple air inlet channels 21 to the top of the heating platform 31, and the heating platform 31 heats the flow channel 19, thereby heating the steam in the steam chamber 16 and the air inlet channel 21, and at the same time, part of the heat burned on the heating platform 31 flows into the interlayer tube 2, and then heats the inner wall of the interlayer tube 2, thereby further heating the steam in the air inlet channel 21. By using multiple guide plates 5 to tilt toward one side of the flow channel 19 in the default state, the heat of the liquid alkane or liquid aromatic hydrocarbon used for heating on the heating platform 31 can be used more for heating the water in the inner water tank 15, so as to quickly heat up and generate steam for water decomposition hydrogen reaction, so that the heat is reasonably used.

[0054] Then, after the multiple air ducts 21 begin to spray high-temperature steam, the high-temperature steam begins to undergo a water-hydrogen decomposition reaction, and the produced hydrogen flows into the air outlet 13, and then passes through the air connecting pipe 33, the annular air pipe 34, the support 35 and the air guide rod 36 to allow the hydrogen to be sprayed out through the exhaust nozzle 41 opened on the top of the exhaust box 4. At this time, due to the fierce combustion of hydrogen, a strong impact force will be generated, which will impact the two first blades 6 through its impact force, thereby causing the two first blades 6 to flip over. When the two first blades 6 flip over, the first ends of the two first blades 6 detach from the vertical plate 37 and fit onto 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 are respectively flipped over the second air passage 42, thereby shielding the top of the second air passage 42 to a certain extent. Therefore, the first end of the first blade 6 is used to shield the first air passage 43; the second end of the first blade 6 blocks the upper part of the second air passage 42 to a certain extent, thereby reducing the contact between the oxygen generated by the decomposition of water vapor and the liquid alkanes or liquid aromatic hydrocarbons burning on the heating table 31, thereby further saving the use of combustion energy.

[0055] Furthermore, when one of the first blades 6 of the shielding plate group is turned over, Fig. 9As shown, at this time, the second end of one of the first blades 6 pushes the bottom end of the guide plate 5, thereby driving the top end of the guide plate 5 to flip toward the inner wall of the interlayer tube 2. At the same time, the torsion spring 51 is deformed and stores force due to the flipping of the guide plate 5. Fig. 9 As shown, the second end of the first blade 6 and the guide plate 5 are tilted to guide the heat flowing through the second air passage 42 to flow into the interlayer tube 2, and at the same time, the heat generated by the combustion of hydrogen ejected from the exhaust nozzle 41 flows into the interlayer tube 2 under the partial guidance of the guide plate 5, so that more heat enters the interlayer tube 2 to more concentratedly and fully carry out the reaction of water decomposition and hydrogen. Therefore, during the production and recycling of hydrogen, the strong impact force generated by the violent combustion of hydrogen is used to drive the first blade 6 to flip, thereby adjusting the flow direction of heat, so as to reasonably use the heat.

[0056] Furthermore, Fig.12 As shown by the middle arrow, the heat flowing through the second air passage 42 is guided to flow into the interlayer tube 2 along the second end of the first blade 6 and the guide plate 5 in an inclined state, and at the same time, the heat generated by the combustion of the hydrogen ejected from the exhaust nozzle 41 flows into the interlayer tube 2 under the partial guidance of the guide plate 5. The exhaust port at the bottom end of the air duct 21 is located above the circular control frame 3. At this time, the heat flowing out of the second air passage 42 and the exhaust nozzle 41 is guided by the guide plate 5 and the first blade 6 to flow into the interlayer tube 2. According to the Bernoulli principle, the greater the flow rate, the lower the pressure. The high-temperature steam discharged at the bottom end of the air duct 21 will flow along with the heat toward the interlayer tube 2, so that the high-temperature steam is guided into the interlayer tube 2 to better carry out the reaction of water decomposition and hydrogen.
