[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Please also read Figures 1 to 6 Now, the catalytic heating device provided in the embodiment of the present application is described. The catalytic heating device comprises an outer shell 10, a hydrogen production device 30 and a heat supply device.

[0033] A heat supply chamber 101 is provided in the outer shell 10; a first air inlet 14 and an air outlet 15 respectively connected to the heat supply chamber 101 are provided on the outer shell 10; a hydrogen production device 30 is arranged in the heat supply chamber 101; a heat supply device is arranged in the heat supply chamber 101; the heat supply device comprises a reaction body 20 and a catalyst body 23, a first reaction chamber 201 is provided in the reaction body 20, a second air inlet 21, a heat exhaust port 22 and a feed port 253 respectively connected to the first reaction chamber 201 are provided on the reaction body 20, the second air inlet 21 is connected to the first air inlet 14 correspondingly, the heat exhaust port 22 is arranged correspondingly to the hydrogen production device 30, external methanol can enter the first reaction chamber 201 through the feed port 253, and the catalyst body 23 is arranged in the first reaction chamber 201 to catalyze a chemical reaction between methanol and oxygen in the first reaction chamber 201.

[0034] For example, Figures 1 to 6 As shown, the outer shell 10 is a columnar structure, and a heating chamber 101 for providing heat to other reaction devices is formed inside the outer shell 10 . A first air inlet 14 and an air outlet 15 respectively connected to the heating chamber 101 are provided on the outer shell 10 . The heating device is arranged in the heating chamber 101, and the heating device can generate heat. The heating device includes a reaction body 20 and a catalyst body 23. A first reaction chamber 201 for chemical reaction is formed in the reaction body 20. The reaction body 20 is provided with a second air inlet 21, a heat exhaust port 22 and a feed port 253 which are respectively connected to the first reaction chamber 201, wherein the second air inlet 21 is connected to the first air inlet 14, and the heat exhaust port 22 is opposite to the hydrogen production device 30. Methanol from the outside can enter the first reaction chamber 201 through the feed port 253. In order to improve the reaction efficiency, the methanol and the air are fully mixed, and the discharged methanol is in a gasified state or an atomized state. The catalyst body 23 is arranged in the first reaction chamber 201, and is used to catalyze the chemical reaction of the methanol and oxygen mixed with each other in the first reaction chamber 201.

[0035] Specifically, methanol (CH3OH) and oxygen (O2) are mixed and then contacted with the catalyst to undergo a chemical reaction and generate a large amount of heat. At the same time, since air is continuously supplied to the first reaction chamber 201 through the second air inlet 21, the original gas in the first reaction chamber 201 will be discharged from the heat exhaust port 22. The discharged gas carries a large amount of heat, thereby providing heat for other reaction devices. At the same time, the reaction body 20 is also arranged in the heating chamber 101, and the heat generated in the reaction body 20 can also provide heat for itself, thereby making the reaction inside the reaction body 20 more sufficient.

[0036] Compared with the prior art, the catalytic heating device provided in the present application is as follows: when the hydrogen production equipment of the present application is working, outside air enters the first reaction chamber 201 through the first air inlet 14 and the second air inlet 21 in turn, and methanol enters the first reaction chamber 201 through the feed port 253 and mixes with the air. Formaldehyde and oxygen in the air react rapidly under the catalytic action of the catalyst in the catalyst body 23, and generate a large amount of heat. The heat is discharged into the heating chamber 101 along with the air flow through the heat exhaust port 22 to heat the hydrogen production device 30, and then the air flow is discharged through the air outlet 15. By arranging the hydrogen production device 30 and the heating device together in the heating chamber 101 of the outer shell 10, the heat generated by the heating device can fully heat the hydrogen production device 30, effectively improving the utilization rate of heat, that is, it is beneficial to reduce the loss of heat. At the same time, the heat generated by the heating device is discharged into the heating chamber 101 and can also heat itself, so as to accelerate the reaction rate of formaldehyde and oxygen in the first reaction chamber 201, and further improve the utilization rate of heat.

[0037] In one embodiment of the present application, please refer to Figure 2 , Figure 4 and Figure 5 The heating device further includes a spoiler 24 , which is disposed in the first reaction chamber 201 and directly opposite to the second air inlet 21 , and a plurality of first ventilation holes 241 are formed on the spoiler 24 .

[0038] Specifically, the spoiler 24 is mainly used to disturb the gas entering the first reaction chamber 201 from the second air inlet 21. In the present embodiment, the spoiler 24 is provided with a plurality of first ventilation holes 241, and the first ventilation holes 241 are circumferentially and evenly distributed on the spoiler 24. When the external gas is blown into the first reaction chamber 201 from the second air inlet 21, it is first blown onto the spoiler 24, and then the airflow is dispersed and passes through the spoiler 24 from the plurality of first ventilation holes 241 respectively, so that the gas cannot pass directly through the first reaction chamber 201, and the airflow is dispersed, so that methanol can be fully mixed with the air, thereby improving the reaction efficiency of the entire catalytic reaction.

[0039] In one embodiment of the present application, please refer to Figure 2 , Figure 4 and Figure 5 A guide block 242 is provided on one side of the spoiler 24 close to the second air inlet 21 .

[0040] Specifically, the guide block 242 is protruding from the side of the spoiler 24 close to the second air inlet 21, and the guide block 242 is located in the middle position of the spoiler 24, and multiple first ventilation holes 241 are circumferentially distributed on the periphery of the guide block 242. At the same time, the second air inlet 21 is directly opposite to the guide block 242, and the diameter of the second air inlet 21 is similar to the diameter of the guide block 242, so that after the external gas enters the first reaction chamber 201 from the second air inlet 21, it must be guided by the guide block 242 before it can pass through the first ventilation holes 241 respectively, wherein the guide block 242 has a guide surface, which is inclined and facing the first ventilation hole 241, so the direction of the airflow passing through the first ventilation hole after being guided by the guide surface is toward the inner wall of the first reaction chamber 201, thereby further dispersing the airflow and making the air and methanol more fully mixed.

[0041] In one embodiment of the present application, please refer to Figure 2 , Figure 4 and Figure 6 The heating device also includes a heating component 25, which is disposed in the first reaction chamber 201 and between the spoiler 24 and the catalyst body 23, and can heat the methanol in the first reaction chamber 201 to gasify the methanol.

[0042] Specifically, the heating component 25 has a heating function, and the heating component 25 is arranged in the first reaction chamber 201. When the heating component 25 starts the heating function, the temperature of the entire heating component 25 increases, thereby causing the temperature of the methanol liquid to increase. Finally, the high-temperature methanol is discharged from the feed port 253 into the first reaction chamber 201 in a vaporized state.

[0043] In one embodiment of the present application, please refer to Figure 2 , Figure 4 and Figure 6 The heat conducting plate 251 is disposed on a side of the spoiler plate 24 away from the second air inlet 21 , and a second ventilation hole 255 is disposed on the heat conducting plate 251 , and the second ventilation hole 255 is disposed opposite to the spoiler plate 24 .

[0044] Specifically, the external gas passes through the second air inlet 21, the spoiler 24, and the heat conducting plate 251 in sequence. After being spoiled by the spoiler 24, the airflow passes through the second ventilation holes 255 on the heat conducting plate 251. The second ventilation holes 255 on the heat conducting plate 251 can further disrupt the airflow entering the first reaction chamber 201. At the same time, since the heat conducting plate 251 is in a high temperature state after being heated by the heating rod 252, the temperature of the airflow increases after passing through the second ventilation holes 255, so that the airflow can react more fully with methanol during the subsequent catalytic reaction.

[0045] In one embodiment of the present application, please refer to Figure 2 , Figure 4 and Figure 6 The heating component 25 includes a heat conducting plate 251 and a heating rod 252. A liquid supply channel is provided in the heat conducting plate 251. The liquid supply channel is connected to the feed port 253 and the first reaction chamber 201. The heating rod 252 is arranged on the heat conducting plate 251. The heat in the heating rod 252 can pass through the heat conducting plate 251.

[0046] Specifically, the heating rod 252 and the heat conducting plate 251 are in contact with each other, and the heat of the heating rod 252 can be transferred to the heat conducting plate 251 by heat transfer. The heat conducting plate 251 is made of heat conducting material, and the heat in the heat conducting rod can be more efficiently transferred to the heat conducting plate 251. At the same time, a liquid supply channel is formed in the heating component 25, and the liquid supply channel is mainly used to transmit methanol liquid. One end of the liquid supply channel is a liquid inlet 254 and the other end is a feed port 253. External methanol liquid enters from the liquid inlet 254, and then passes through the liquid conducting channel and is discharged from the feed port 253 to the first reaction chamber 201. When the heating component 25 starts the heating function, the temperature of the entire heating component 25 increases, thereby causing the temperature of the methanol liquid in the liquid supply channel to increase. Finally, the high-temperature methanol is discharged from the feed port 253 to the first reaction chamber 201 in a vaporized state.

[0047] In one embodiment of the present application, please refer to Figure 2 , Figure 4 and Figure 6 , the heating rod 252 is embedded in the heat conducting plate 251 .

[0048] Specifically, by embedding the heating rod 252 inside the heat conductive plate 251, the heat of the heating rod 252 is prevented from being dissipated into the surrounding air during the heat transfer process to the heat conductive plate 251. At the same time, the heating rod 252 is embedded inside the heat conductive plate 251 so that the heat conductive plate 251 is in full contact with the outer surface of the heating rod 252, thereby improving the efficiency of the heating rod 252 in heating the heat conductive plate 251.

[0049] In one embodiment of the present application, please refer to Figure 2 and Figure 4 The catalyst body 23 is in a honeycomb shape.

[0050] Specifically, a catalyst for catalyzing a chemical reaction between oxygen and gasified methanol is provided in the catalyst body 23. After the air and methanol are mixed, they contact the catalyst in the catalyst body 23, which can make the catalytic reaction more effective. The first reaction chamber 201 includes a mixing chamber and a catalytic chamber. The inner side of the first reaction chamber 201 is provided with an annular limiting convex portion, which is arranged between the mixing chamber and the catalytic chamber. The mixing chamber is located on the side of the first reaction chamber 201 close to the second air inlet 21, and the catalytic chamber is located on the side of the first reaction chamber 201 close to the heat exhaust port 22. On one side, the spoiler 24 and the heat conducting plate 251 are both arranged in the mixing chamber, and the catalyst body 23 is arranged in the catalytic chamber. The catalyst body 23 abuts against the side of the annular limiting protrusion close to the heat exhaust port 22 to prevent the catalyst body 23 from entering the mixing chamber. In this embodiment, the catalyst body 23 has a honeycomb structure, and a plurality of air holes are provided on the catalyst body 23. One end of the plurality of air holes faces the second air inlet 21, and the other end faces the heat exhaust port 22, so that the airflow can pass through the plurality of air holes in a dispersed manner, thereby reacting more fully with the catalyst body 23.

[0051] In one embodiment of the present application, please refer to Figure 2 The outer shell 10 includes an outer layer 11 , an inner layer 12 and a heat-insulating layer 13 , and the heat-insulating layer 13 is sandwiched between the outer layer 11 and the inner layer 12 .

[0052] Specifically, the insulation layer 13 is an insulation material. By sandwiching the insulation material between the outer layer 11 and the inner layer 12, it can effectively delay the heat loss in the heating cavity 101, further reduce the energy consumption in the heating process, and improve the heat utilization rate of the entire catalytic heating device.

[0053] In one embodiment of the present application, please refer to Figure 2 The outer shell 10 is provided with a first air inlet 14 and an air outlet 15 . The first air inlet 14 is connected to the second air inlet 21 . The air outlet 15 is connected to the heating chamber 101 . The air outlet 15 is arranged on a side of the outer shell 10 away from the heat exhaust port 22 .

[0054] Specifically, Figure 2 As shown in the air flow route diagram in the figure, the airflow discharged from the heat exhaust port 22 after the catalytic reaction will move in the direction away from the first air inlet 14 without hitting any external objects, and the direction of the airflow will not be changed until it touches the inner wall surface of the outer shell 10. By setting the air outlet 15 on the side of the outer shell 10 away from the heat exhaust port 22, the airflow discharged from the heat exhaust port 22 can move in the opposite direction and be discharged in the direction of the heat exhaust port 22 after reaching the inner wall of the outer shell 10, so that the high-temperature gas discharged from the heat exhaust port 22 can fill the entire heating chamber 101 as much as possible, so that the heat distribution in the heating chamber 101 is more uniform.

[0055] In one embodiment of the present application, please refer to Figures 1 to 6 The hydrogen production device 30 includes a recombinant body 31 and a purification body 32. The recombinant body 31 forms a heating chamber and a second reaction chamber 311 which are isolated from each other. The heating chamber is connected with the heat supply chamber 101 and the heat exhaust port 22. A catalyst is stored in the second reaction chamber 311, and the second reaction chamber 311 is surrounded by the outer peripheral side of the heating chamber. The purification body 32 is arranged in the heating chamber.

[0056] Specifically, the catalyst in the second reaction chamber 311 is the same as the catalyst in the aforementioned catalyst body 23. The recombining body 31 is an annular structure with openings at both ends. The second reaction chamber 311 is surrounded by the periphery of the heating chamber. The reaction body 20 is arranged at the opening on the side of the recombining body 31 close to the second air inlet 21. The hot gas discharged from the heat exhaust port 22 directly enters the heating chamber, and the heat in the heating chamber can be transferred to the second reaction chamber 311. At the same time, the purification body 32 is arranged in the heating chamber, so the hot gas can directly heat the purification body 32.

[0057] Specifically, Figure 2 As shown in the air flow route diagram, the gas in the heating chamber is discharged from the opening at the end of the heavy body 31 away from the reaction body 20, and then flows along the inner wall surface of the outer shell 10 to the air outlet 15. In this process, the high-temperature airflow will pass through the outer side surface of the heavy body 31 for the second time, thereby further heating the heating chamber and the second reaction chamber 311, further improving the efficiency of heating and improving the utilization rate of heat.

[0058] Specifically, a control valve is provided between the second reaction chamber 311 and the purification body 32. When the catalyst in the second reaction chamber 311 reaches the reaction temperature, methanol water is introduced into the second reaction chamber 311, so that the methanol water and the catalyst generate secondary hydrogen gas in the second reaction chamber 311. Then, the control valve is opened to pass the secondary hydrogen gas into the purification body 32 to purify pure hydrogen gas.

[0059] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for explaining the principles of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementations of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
