Description

Technical Field

[0001] This utility model relates to the field of natural gas hydrogen production technology, specifically a natural gas hydrogen production reactor. Background Technology

[0002] Hydrogen production refers to a series of technologies that use industrial methods to produce hydrogen. Most hydrogen is produced by the reforming of natural gas steam. Other major sources include the reforming of naphtha or oil from refineries or other industrial waste gases, as well as the partial oxidation of coal and other hydrocarbons. A small portion is obtained through water electrolysis and other sources. Traditional natural gas hydrogen production processes are usually accompanied by the generation of carbon dioxide. If this carbon dioxide is directly released into the atmosphere, it will exacerbate the greenhouse effect.

[0003] Natural gas is mainly composed of methane, which can be converted into hydrogen through hydrocarbon steam reforming. It has the advantages of high purity and high efficiency. However, the process of producing hydrogen from natural gas will produce tail gas containing a large amount of carbon dioxide. By capturing this carbon dioxide that would otherwise be emitted and permanently storing or effectively utilizing it, the carbon footprint of the hydrogen production process can be significantly reduced. Therefore, this utility model proposes a natural gas hydrogen production reactor. Utility Model Content

The first fixing plate and the second fixing plate abut against each other. Both the first fixing plate and the second fixing plate have through holes. A screw is movably connected to the inner wall of the through hole, and a nut is threaded onto the surface of the screw.

A first support block 303 is fixedly connected to one side of the fixed disk 301. A rotating disk 304 is slidably connected to the side of the first support block 303. One side of the rotating disk 304 is slidably connected to one side of the fixed disk 301. A second opening 305 is provided on the rotating disk 304. The first opening 302 and the second opening 305 cooperate with each other. A second support block 306 is fixedly connected to one side of 04. By rotating the rotating disk 304, the position of the second port 305 can be adjusted to match the first port 302, thereby controlling the communication state inside the connecting pipe 4. When the positions of the first port 302 and the second port 305 overlap, the flow rate inside the connecting pipe 4 is the maximum. When the positions of the first port 302 and the second port 305 do not intersect at all, the connecting pipe 4 is in a closed state. The first support block 303 is set to support the rotation of the rotating disk 304.

[0018] Reference Figure 1 and Figure 2 A first fixing plate 5 is fixedly connected to the outer side of the carbon outlet 2, and a second fixing plate 6 is fixedly connected to the outer side of the connecting pipe 4.

A screw 8 is movably connected to the inner wall of the through hole 7. A nut 9 is threaded onto the surface of the screw 8. By setting the first fixing plate 18 and the second fixing plate 18, the screw 8 is passed through the through hole 7, and then the nut 9 is tightened on the screw 8, so that the connecting pipe 4 can be assembled to the carbon outlet 2.

[0019] Reference Figure 4 A roller 10 is fitted onto the second support block 306, and a guide plate 11 is provided below the rotating disk 304. A guide groove 12 is provided on the guide plate 11, and the roller 10 rolls in the guide groove 12. The guide groove 12 on the guide plate 11 is used to guide the movement of the second support block 306 in conjunction with the roller 10. The roller 10 is used to lubricate the guiding process. The second support block 306 is moved horizontally in the opposite direction to drive the rotating disk 304 to rotate.

[0020] Reference Figure 4 and Figure 5A guide block 13 is fixedly connected to one side of the guide plate 11. A threaded rod 14 is threadedly connected to the inner wall of the guide block 13. A bearing 15 is fixedly connected to one end of the threaded rod 14. By rotating the threaded rod 14, the guide block 13 threadedly connected to it can be moved, thereby driving the guide plate 11 fixedly connected to the guide block 13.

[0021] Reference Figure 4 and Figure 5 A first baffle 16 is movably connected to the side of the threaded rod 14, and a second baffle 17 is movably connected to the surface of the threaded rod 14. A fixing plate 18 is fixedly connected to the side of the second baffle 17. The side of the guide block 13 is slidably connected to the inner wall of the fixing plate 18, and the inner wall of the fixing plate 18 is fixedly connected to the side of the first baffle 16. By setting the first baffle 16 and the second baffle 17, the rotation arc of the rotating disk 304 is limited. When the guide block 13 abuts against the first baffle 16, the connecting pipe 4 is closed. When the guide block 13 abuts against the second baffle 17, the connecting pipe 4 is connected and in the maximum flow state, which facilitates the determination of the connection state of the connecting pipe 4. The fixing plate 18 is set to assemble the first baffle 16 and the second baffle 17. By setting the fixing plate 18, the guide block 13 can remain stable during the movement. The bearing 15 is fixedly connected to the assembly box 20, which can maintain the stable rotation of the threaded rod 14.

[0022] Reference Figure 4 and Figure 5 A motor 19 is fixedly connected to one side of the first baffle 16. The output end of the motor 19 is fixedly connected to one end of the threaded rod 14. The output end of the motor 19 rotates inside the first baffle 16. An assembly box 20 is fixedly connected to one side of the fixed plate 18. The inner wall of the assembly box 20 is fixedly connected to the outer side of the connecting pipe 4. The inner wall of the assembly box 20 is fixedly connected to the bearing 15. The motor 19 is used to drive the threaded rod 14 to rotate. The assembly box 20 is used to support the fixed plate 18 and the components connected to the fixed plate 18.

[0023] Reference Figure 1 One end of the connecting pipe 4 is connected to the guide pipe 21. The natural gas hydrogen production reactor body 1 is connected to the feed port 22 and the natural gas hydrogen production reactor body 1 is connected to the discharge port 23. After the material enters the natural gas hydrogen production reactor body 1 through the feed port 22, hydrogen production begins. The generated hydrogen is discharged through the discharge port 23, and the generated carbon dioxide enters the connecting pipe 4 through the carbon outlet 2. Finally, it enters the guide pipe 21 and is introduced into the carbon dioxide capture device to reduce the carbon footprint of the hydrogen production process.

[0024] Working principle: During operation, the material is fed into the natural gas hydrogen production reactor body 1 through the feed inlet 22 for hydrogen production. The generated hydrogen is discharged through the discharge outlet 23, and the generated carbon dioxide enters the connecting pipe 4 through the carbon outlet 2. The carbon dioxide then enters the guide pipe 21 through the first port 302 and the second port 305, and then enters the guide pipe 21. The gas containing carbon dioxide is then introduced into the carbon dioxide capture device through the guide pipe 21 to reduce the carbon dioxide emissions from the natural gas hydrogen production. When it is necessary to stop carbon dioxide discharge due to maintenance or replacement of the carbon dioxide capture device, the motor 19 is started to drive the threaded... The rod 14 rotates, causing the guide block 13 to gradually move from the first baffle 16 towards the second baffle 17. During this process, the guide plate 11 drives the second support block 306 to move horizontally, and the second support block 306 drives the rotating disk 304 to rotate. When the guide block 13 abuts against the second baffle 17, the first port 302 and the second port 305 do not intersect at all, and the connecting pipe 4 is closed. When carbon discharge needs to be restored, the motor 19 is started in reverse, and the threaded rod 14 drives the guide block 13 to gradually move from the second baffle 17 towards the first baffle 16. When the guide block 13 abuts against the first baffle 16, the connecting pipe 4 is restored to communication.
