[0024] Implementation Method 1 Reference Figures 1 to 6 This embodiment is an optional embodiment of the present application, which discloses a catalytic reaction module for producing hydrogen from methanol, including a support frame 1, wherein the support frame 1 includes a plurality of support rods 101, preferably, three support rods 101 are preferably used, and each support rod 101 is arranged in a triangular structure, and a connecting frame 102 is also provided at the top and bottom of the support rod 101, and each support rod 101 is connected by the connecting frame 102 to ensure the stability of the structure; The support frame 1 further includes a plurality of support plates 2, which are distributed in sequence along the height direction of the support frame 1 and are respectively connected to the frame body; It should be noted that the number of support plates 2 can be flexibly adjusted as needed to more fully utilize the internal space of the tank; In the above structure, each reaction box 3 is arranged in sequence in the height direction, which not only makes higher use of the space in the tank body, but also can effectively control the length of the airflow path, thereby avoiding the occurrence of long-distance invalid paths, ensuring that the hydrogen produced by catalysis can be discharged at the fastest speed, thereby improving the hydrogen production efficiency of the equipment.

[0025] An adjustment seat is provided on at least one support rod 101, and a slide seat 17 is slidably provided on the other support rods 101, wherein the adjustment seat includes a lifting sleeve 18 and a support seat 19, and the lifting sleeve 18 is threadedly connected to the support rod 101; the lifting sleeve 18 is rotatably connected to the support seat 19 through a thrust ball bearing 20; a mounting hole is provided on the support plate 2, and the support seat 19 is inserted into the mounting hole, and a limiting rod 21 is provided on the support plate 2, and a limiting hole 22 is provided on the support seat 19, and the limiting rod 21 is inserted into the limiting hole 22; The slide 17 is a round structure, and the slide 17 is slidably sleeved on the support rod 101. A fixing assembly is also provided between the slide 17 and the support rod 101, and the fixing assembly includes a fixing screw 23, and the fixing screw 23 is threadedly connected to the slide 17. A fixing groove 24 adapted to the fixing screw 23 is provided on the support rod 101; When in use, loosen the fastening screw, and then rotate the lifting sleeve 18 to control the height of the entire adjustment seat, and the change in the height position of the adjustment seat will drive the support plate 2 to rise or fall. After adjusting to the right position, the support plate 2 can be fixed by the fixing screw 23; The above structure can facilitate the staff to adjust the position of the support plate 2 according to the needs, especially when assembling the equipment, the position of the support plate 2 can be quickly adjusted through the above device, thereby improving the assembly accuracy and reducing the requirements for the equipment production accuracy; Secondly, through the above arrangement, the arrangement of the support plate 2 can be made more compact, and during the disassembly and assembly process, the gap between two adjacent support plates 2 can be effectively expanded, which facilitates the removal and installation of the reaction box 3 to accommodate more reaction boxes 3; Finally, since the position of the support plate 2 can be adjusted, in actual use, the reaction boxes 3 of different specifications can be replaced according to needs, thereby providing reaction boxes 3 with different catalytic capabilities to meet different usage requirements.

[0026] A reaction box 3 is disposed on each of the support plates 2. The reaction box 3 includes a box body 301 and a cover plate 309. An air inlet 302 and an air outlet 303 are also disposed on the box body 301. The reaction box 3 is an annular structure as a whole, and the central cavity is a heating chamber. The setting of the heating chamber can, on the one hand, expand the contact surface between the reaction box 3 and the heat exchange medium such as heating oil, thereby improving the heat transfer efficiency; on the other hand, the heating chamber can guide the heat exchange medium such as heating oil to enter the middle area of ​​the reaction box 3, thereby heating the heating box of the annular structure in both the inner and outer directions, which can effectively avoid the heating blind area, improve the uniformity of the temperature in the reaction box 3, and ensure the efficiency of catalytic hydrogen production; A plurality of guide plates 304 are also arranged in the box body 301. The guide plates 304 are arranged in an arc-shaped structure. The arc of each guide plate 304 is preferably 250°-270°. The radius of each guide plate 304 increases successively. With the center of the box body 301 as the center point, each guide ring is arranged in a concentric circle structure. Between two adjacent guide plates 304 is a filling area, which is filled with a catalyst. The arc of 250°-270° can ensure that an empty area is formed in the box body 301. A partition is arranged in the above-mentioned empty area. The two ends of the partition are respectively connected to the inner walls of the two sides of the box body 301. The box body 301 is also provided with an air inlet 302 and an air outlet 303. The air inlet 302 and the air outlet 303 are both connected to the air pipe. At the same time, the air inlet pipe 4 and the air outlet pipe are respectively arranged on both sides of the partition; The above-mentioned vacant area is divided into two parts separated from each other by a partition, and the two areas are respectively connected to the inlet and outlet of each filling area; at the same time, the air inlet 302 is isolated from the air outlet 303 by the setting of the partition, so that the gas can only be discharged after rotating around the axis of the box body 301 for one circle, thereby ensuring that the methanol vapor and water vapor can only flow along the prescribed path in the box body 301, ensuring their retention time, and preventing a large amount of methanol vapor and water vapor from mixing into the tail gas, thereby ensuring the recovery rate of hydrogen; In the above structure, the guide plates 304 arranged in a concentric circle structure can be used to set up several airflow channels in parallel in the box 301. On the one hand, the contact area between the catalyst and the methanol vapor is increased, which is beneficial to improving the catalytic reaction efficiency; on the other hand, the airflow can be more reasonably distributed to ensure that the catalysts in different areas have high-concentration methanol vapor passing through, thereby avoiding the accumulation of methanol vapor at the inlet end. Finally, the above structural arrangement can more reasonably utilize the space in the reaction box 3 and improve the efficiency of catalytic hydrogen production.

[0027] It should be noted that in the above technical solution, one or two filling areas can be combined by setting a closed outlet and setting a new opening, so as to form a maze-like airflow path in the box 301, thereby ensuring the retention time of the airflow in the box 301 and ensuring the recovery rate of hydrogen; The cover plate 309 is provided with a plug-in slot 310 on one side that is in contact with the box body 301. The top surface of the box body 301 is provided with a plug-in ring 311 that matches the plug-in slot 310. The plug-in ring 311 is inserted into the plug-in slot 310. A filling rubber sealing ring is also provided in the plug-in slot 310 to achieve sealing of small gaps. A matching flange plate is also provided between the cover plate 309 and the box body 301, and the flange plates are connected by connecting bolts; At the same time, a sealing gasket is also arranged inside the plug-in slot 310. The shape of the sealing gasket is exactly the same as the distribution of the guide plate 304. After installation, the sealing gasket is located between the cover plate 309 and the guide plate 304, thereby sealing the gap between the cover plate 309 and the guide plate 304 to prevent gas from flowing from the top of the guide plate 304, ensuring that gases such as methanol vapor can only move along a specified route; Furthermore, in the filling area located on the inner side, since it is close to the center of the box body 301, its radius is smaller and its path is shorter. Therefore, in order to ensure the catalytic conversion efficiency, baffles can be further provided in the above-mentioned filling area. The baffles are staggered to form an S-shaped airflow path, thereby ensuring that the airflow paths in different channels are basically equal and the hydrogen recovery rate is ensured. The above-mentioned arrangement has a simple structure and low cost.

[0028] Two mutually parallel slide rails 9 are arranged on each of the support plates 2, and a slide groove 10 is arranged on each of the two slide rails 9. A roller 11 is arranged at the bottom of the box body 301 of the reaction box 3, and the roller 11 is inserted into the slide groove 10. At the same time, a guide block is also arranged at the outlet end of the slide groove 10, and the top surface of the guide block is arranged obliquely; A locking assembly is also provided between the reaction box 3 and the support plate 2, and the locking assembly includes a locking rod 12 and a locking sleeve 13. Along the sliding direction of the reaction box 3, both sides of the reaction box 3 are provided with a limiting frame 14, and the locking rod 12 is threadedly connected to the limiting frame 14; the locking sleeve 13 is provided on the reaction box 3; The above-mentioned structural setting enables the reaction box 3 to have a certain sliding ability. When removing the reaction box 3 or reinstalling the reaction box 3, the reaction box 3 can be pulled or pushed, which makes the installation easier and labor-saving, and is conducive to improving work efficiency.

[0029] Furthermore, the catalytic reaction module further includes an air inlet pipe 4 and an air outlet pipe, one end of the air inlet pipe 4 is connected to an external gas source, and the other end of the air inlet pipe 4 is respectively connected in parallel with the inlet end of each of the reaction boxes 3; one end of the exhaust pipe 5 is connected to a hydrogen storage device, and the other end thereof is respectively connected in parallel with the outlet end of each of the reactors; A hydrogen sensor 6 and a flow sensor 7 are provided at the outlet end of the reaction box 3 . The catalytic reaction module further comprises a controller 8 . The controller 8 is electrically connected to each of the hydrogen sensors 6 and each of the flow sensors 7 .

[0030] At the same time, an insulation pipe 15 is sleeved on the air inlet pipe 4 and the air outlet pipe, and a spiral guide plate 16 is arranged between the insulation pipe 15 and the air inlet pipe 4, and between the insulation pipe 15 and the exhaust pipe 5; With the above-mentioned structural arrangement, the air inlet pipe 4 and the air outlet pipe can be arranged outside the tank body, and the hydrogen sensor 6 and the flow sensor 7 can also be arranged outside the tank body, thereby avoiding the adverse effect of the heat exchange medium on the sensor; At the same time, the above arrangement can also avoid too many pipelines inside the tank, reducing the difficulty of equipment maintenance and disassembly; At the same time, the heat preservation pipe 15 can be used to insulate the external air inlet pipe 4 and the air outlet pipe and recover heat, which is not only beneficial to ensure the temperature of the mixed gas, but also beneficial to reduce the energy consumption of the equipment; The parameters of the hydrogen sensor 6 and the flow sensor 7 can accurately monitor the hydrogen recovery rate at the outlet, which is not only conducive to improving the monitoring capability of the working state of the equipment; at the same time, under the condition of uninterrupted mixed gas at the inlet, if the hydrogen recovery rate at the outlet is significantly reduced, it can be determined that the catalyst in the reaction box 3 is invalid and needs to be replaced; At this time, the controller 8 will issue an instruction to replace the catalyst, and quickly determine the specific reaction box 3 according to the position of the hydrogen sensor 6, helping the staff to quickly locate the failed reaction box 3 and improve the maintenance efficiency; Secondly, while issuing an alarm, the controller 8 can also shut down the reaction box 3, on the one hand to avoid the waste of reaction raw gases such as methanol vapor and water vapor, and on the other hand to avoid a large amount of methanol vapor and water vapor being directly discharged into the tail gas without conversion, thereby ensuring the stability of the hydrogen recovery rate.

[0031] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
