[0002] Hydrogen is usually generated by the reaction of methanol and water in a converter. The hydrogen production reaction needs to be carried out at a temperature of 200-300 °C. There is heat-conducting oil in the tank body of the converter, which can transfer heat to the materials in the converter, so that the mixture of methanol and water can reach and maintain within a suitable reaction temperature range to ensure the smooth progress of the reaction. The existing hydrogen production converters are usually selected according to the gas consumption of hydrogen required by kilns and boilers. For different hydrogen gas consumption, converters of different capacities need to be made. Basically, each type of converter needs to be redesigned and processed, which greatly increases the production cost. Summary of the Utility Model

[0016] Referring to Figure 1 , the modular hydrogen production device includes a heat transfer oil tank body 1 and reaction units. A circular installation port 101 is provided on the upper side of the heat transfer oil tank body 1, and the reaction units are correspondingly installed on each installation port 101. The number of reaction units is selected according to the hydrogen consumption required by the kiln or boiler, which is much easier than formulating converters with different capacities, saving time and effort.

[0017] Specifically, the reaction units are arranged on the heat transfer oil tank body 1. The reaction units include an upper head, reaction tubes 2, a hydrogen outlet pipeline 3 and a lower head. The upper head covers the heat transfer oil tank body 1, and the reaction tubes 2 and the hydrogen outlet pipeline 3 are arranged between the upper head and the lower head, and the reaction tubes 2, the hydrogen outlet pipeline 3 and the lower head are arranged inside the heat transfer oil tank body 1.

[0018] The upper head includes an upper sealing cover 4, an upper tank body 5 and an upper porous flange 6. The upper porous flange 6 covers the circular installation opening 101 and is fixed to the heat-conducting oil tank body 1 by bolts. A gasket 9 is arranged between the upper porous flange 6 and the heat-conducting oil tank body 1 for sealing. The number of circular holes in the middle of the upper porous flange 6 is the same as that in the middle of the lower porous flange 8. The reaction tubes 2 and the hydrogen outlet pipeline 3 are installed between the two flanges. The upper tank body 5 and the upper sealing cover 4 are sequentially arranged on the upper side of the upper porous flange 6 from bottom to top. The lower side of the cylindrical upper tank body 5 is welded to the upper porous flange 6, and the upper side is fixedly connected to the single-hole flange by bolts. The upper sealing cover 4 is welded to the single-hole flange. It is arranged between the upper sealing cover 4 and the upper porous flange 6, and the reaction tubes 2 and the hydrogen outlet pipeline 3 pass through the upper porous flange 6 to communicate with the upper tank body 5. The upper head composed of the upper sealing cover 4, the upper tank body 5 and the upper porous flange 6 is arranged on the upper side of the heat-conducting oil tank body 1, and the reaction tubes 2 and the hydrogen outlet pipeline 3 and the lower head are arranged in the heat-conducting oil tank body 1 and are in full contact with the heat-conducting oil.

[0019] A hydrogen outlet 501 is arranged on the upper tank body 5 of the present utility model. There is one hydrogen outlet pipeline 3, which passes through the upper porous flange 6 to communicate with the hydrogen outlet 501.

[0020] The lower head includes a lower sealing cover 7 and a lower porous flange 8. The lower sealing cover 7 is welded to the lower side of the lower porous flange 8, and a hydrogen storage chamber is formed between them. The reaction tubes 2 and the hydrogen outlet pipeline 3 pass through the lower porous flange 8 to communicate with the hydrogen storage chamber. A catalyst bed is arranged in the reaction tubes 2. The generated hydrogen flows into the hydrogen storage chamber, then flows out through the hydrogen outlet pipeline 3, and finally enters the kiln or boiler through the hydrogen outlet 501 for combustion use.

[0021] Working process:

[0022] For the production module of the present utility model, according to the hydrogen consumption required by the kiln or boiler, the number of reaction units is increased or decreased. After determining the number of reaction units, by designing the volume of the heat-conducting oil tank body 1, or directly increasing or decreasing the reaction units on the original heat-conducting oil tank body 1, the installation opening 101 is installed on the heat-conducting oil tank body 1. Compared with redesigning the converter, it is simple, fast, time-saving and labor-saving.
