Description

Technical Field

[0001] This utility model relates to the field of methanol-to-hydrogen technology, specifically to a methanol-to-hydrogen device with a catalyst layered placement structure. Background Technology

[0002] A methanol-to-hydrogen (MTO) unit is a complete set of equipment that uses methanol and water as raw materials to produce hydrogen through a chemical reaction (mainly methanol steam reforming). Its core function is to convert the chemical energy of methanol into hydrogen, providing high-purity hydrogen for fuel cells, chemical synthesis, metal processing, and other fields.

[0003] In existing technologies, the traditional method of hydrogen production is through electrolysis. Compared to methanol cracking, electrolysis has significant drawbacks. Firstly, it has higher energy consumption, requiring a large amount of electricity during production, making its overall energy consumption far higher than methanol-to-hydrogen. Secondly, it is less economical, with electricity accounting for a large proportion of the cost, while methanol-to-hydrogen is much cheaper. Furthermore, electrolysis is highly dependent on a stable power supply; if relying on renewable energy, it is subject to natural conditions and often requires energy storage equipment; methanol-to-hydrogen, on the other hand, can flexibly control production by adjusting the feed rate. In addition, the initial investment for an electrolyzer is significantly higher than that of a methanol-to-hydrogen plant of the same scale, and the system integration is more complex, involving power rectification, temperature control, etc., making operation and maintenance more difficult. These factors make electrolysis face more challenges in practical applications. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. It uses a medium inlet to feed a mixture of methanol and water. A heating base heats the mixture to vaporize it.

By placing the catalyst tank 3 on the methanol-to-hydrogen tank 1, the methanol-to-hydrogen tank 1 comes into contact with the second temperature sensor 808 on the catalyst tank 3. The methanol-to-hydrogen tank 1 is connected to the heating base 2 by a first fixing bolt 802. A mixture of methanol and water is fed into the methanol-to-hydrogen tank 1 through a medium inlet 4 on the heating base 2. The heating base 2 heats the methanol-to-hydrogen tank 1, causing the mixed liquid inside to vaporize under high temperature. Inside the methanol-to-hydrogen tank 1, several evenly distributed isolation plates 807 are provided. These isolation plates 807 are fixed by the connecting support plate 806 and the second fixing bolt 805, dividing the internal space of the tank into multiple independent areas. Each area can hold different catalysts, achieving layered placement of the catalysts.

[0024] Please see Figure 2-3 A further solution based on this embodiment is as follows: a plurality of isolation plates 807 are provided, and the plurality of isolation plates 807 are uniformly fixedly connected inside the methanol-to-hydrogen tank 1. By uniformly distributing and connecting a plurality of first fixing bolts 802, and in conjunction with the installation fixing ring 801, the methanol-to-hydrogen tank 1 and the catalyst tank 3 can be fixed from multiple points, which greatly enhances the stability and firmness of the connection between the two and effectively prevents the connection from loosening due to vibration and other factors during the operation of the device.

[0025] Please see Figure 2-3 A further solution based on this embodiment is as follows: a plurality of first fixing bolts 802 are provided, and the plurality of first fixing bolts 802 are evenly threadedly connected to the interior of the fixing ring 801 between the methanol hydrogen production tank 1 and the catalyst tank 3. By evenly distributing and connecting the plurality of first fixing bolts 802, the methanol hydrogen production tank 1 and the catalyst tank 3 can be fixed from multiple points in conjunction with the fixing ring 801, which greatly enhances the stability and firmness of the connection between the two.

[0026] Please see Figure 2-3 A further solution based on this embodiment is as follows: a plurality of second fixing bolts 805 are provided, and the plurality of second fixing bolts 805 are evenly threadedly connected between the isolation plate 807 and the connecting support plate 806.

[0027] Please see Figure 4-5 A further embodiment of this solution is as follows: the airflow guiding component includes a first motor 901 fixedly connected to the bottom of the heating base 2, a first rotating rod 902 fixedly connected to the output end of the first motor 901, a stirring paddle 903 fixedly connected to the first rotating rod 902, a mounting support plate 909 fixedly connected inside the methanol-to-hydrogen tank 1, a fixed connecting pipe 904 fixedly connected to the mounting support plate 909, a support connecting frame 905 fixedly connected inside the fixed connecting pipe 904, a second motor 906 fixedly connected to the bottom of the support connecting frame 905, a second rotating rod 907 fixedly connected to the output end of the second motor 906, and a fan 908 fixedly connected to the second rotating rod 907. The second rotating rod 907 is rotatably connected inside the fixed connecting pipe 904. By setting up the airflow guiding component, the first motor 901 drives the stirring paddle 903 to rotate, which can fully stir the material at the bottom of the methanol-to-hydrogen tank 1, making the material more uniformly mixed and improving the completeness of the reaction. The second motor 906 drives the fan 908 to rotate, which can form a directional airflow inside the fixed connecting pipe 904.

[0028] Please see Figure 4-5 A further solution based on this embodiment is as follows: two support connecting frames 905 are provided, and the two support connecting frames 905 are symmetrically fixedly connected inside the fixed connecting pipe 904. By setting two symmetrical support connecting frames 905, stable support can be provided for the second motor 906 and the second rotating rod 907, ensuring that they will not shake or deviate during high-speed rotation, and ensuring that the fan 908 can stably guide the airflow. At the same time, the symmetrical structural design also makes the force inside the fixed connecting pipe 904 more balanced.

[0029] Please see Figure 4-5A further solution based on this embodiment is as follows: a funnel-shaped guide port is provided above the fixed connecting pipe 904. The vaporized gas flows out through the guide port. By designing the funnel-shaped guide port, the vaporized gas can be effectively gathered and guided, increasing the outflow area of ​​the gas and reducing the resistance of the gas during the flow process. This allows the gas to enter the subsequent catalytic tank 3 more smoothly from the fixed connecting pipe 904, avoiding the stagnation and congestion of the gas at the outlet of the fixed connecting pipe 904.

[0030] Please see Figure 4-5 A further solution based on this embodiment is as follows: a plurality of stirring paddles 903 are provided on the first rotating rod 902, and two stirring paddles 903 are evenly fixedly connected to the first rotating rod 902. By setting a plurality of evenly distributed stirring paddles 903, the material at the bottom of the methanol-to-hydrogen tank 1 can be stirred in all directions and at multiple angles when the first rotating rod 902 rotates, so that the material is heated more evenly, the gasification and reaction speed of the material are accelerated, and the situation of incomplete reaction due to insufficient stirring of local materials is avoided.

[0031] Working Principle: A mixture of methanol and water is fed into the methanol-to-hydrogen tank 1 through the medium inlet 4 located on the heating base 2. The heating base 2 heats the methanol-to-hydrogen tank 1, causing the mixed liquid inside to vaporize under high temperature. Inside the methanol-to-hydrogen tank 1, several evenly distributed partition plates 807 are installed. These partition plates 807 are fixed by connecting support plates 806 and second fixing bolts 805, dividing the tank space into multiple independent areas. Each area can hold different catalysts, achieving layered placement of catalysts. The vaporized mixed gas flows orderly under the action of the airflow guiding component. The first motor 901 in the airflow guiding component drives the first rotating rod 902 and the stirring paddle 903 above it to rotate, further stirring the material and making it more uniformly mixed. At the same time, the second motor 906 drives the fan 908 on the second rotating rod 907 to rotate, forming a directional airflow in the fixed connecting pipe 904, guiding the vaporized gas to the catalyst tank 3. When the gas enters the catalyst tank 3, it comes into contact with the catalyst inside the tank. Because the catalysts are layered, different layers can specifically decompose the gas into products such as carbon dioxide, carbon monoxide, hydrogen, and methane. Throughout the process, the first temperature sensor 803 and the second temperature sensor 808 monitor the temperature inside the catalytic converter 3 and the methanol-to-hydrogen tank 1 in real time, facilitating timely adjustments to the reaction conditions. The mounting ring 801 and the first fixing bolt 802 ensure the stability of the connection between the methanol-to-hydrogen tank 1 and the catalytic converter 3 and the heating base 2. The safety valve 804 automatically releases pressure when the internal pressure of the device is too high, ensuring the safe conduct of the reaction. Finally, the mixed gas produced by the reaction is discharged through the medium outlet 5 on the catalytic converter 3.
