[0010] Preferably, the tank body is connected to an oil replenishing pipeline, and the oil replenishing pipeline is connected to the expansion tank.

[0011] Preferably, a supporting leg is fixedly provided on the bottom of the tank body.

[0012] Compared with the prior art, the above technical solution has the following beneficial effects:

[0013] 1. The heating component of the utility model is installed on the upper side of the tank body, and the conveying coil is wound around the heating component. The hydrogen-producing medium enters the tank body through the conveying coil. The heating component heats the oil in the tank body, and the hydrogen-producing medium in the conveying coil is heated by the high-temperature oil in the tank body. The hydrogen-producing medium after evaporation and heating is then transported to the converter to produce hydrogen. The heating component in the device is installed on the upper side of the tank body, which is convenient for installation and maintenance, improves work efficiency, and the heating component is more convenient to install and seal from the upper side and has a better seal.

[0014] 2. The temperature inside the heating tank is relatively high, but the oil temperature close to the heating component is higher than the oil temperature far away from the heating component. Therefore, the heating tank is connected to a circulation pipeline, and a circulation pump is arranged on the circulation pipeline.

[0016] 4. The tank body is connected to an oil replenishing pipeline, which is connected to an expansion tank. The oil expands when heated. Therefore, if the oil in the tank body is filled up in a cooling environment, the oil will expand when heated. However, if the oil is not filled up directly, there will still be a certain dry burning problem. Therefore, the expansion tank is connected. When the oil level in the tank body expands, it enters the expansion tank through the oil replenishing pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] Figures 1 to 3 It is the best embodiment of the utility model, and the following Figures 1 to 3 The utility model is further described.

[0022] like Figure 1As shown, a hydrogen production heating device of the utility model includes a tank body, a heating component 4 and a conveying coil 11. A tank mouth is arranged on the top of the tank body. The heating component 4 is installed from the tank mouth on the upper side of the tank body to the inside of the tank body, and the connection between the heating component 4 and the tank body is sealed and connected. The conveying coil 11 is installed in the tank body, and the conveying coil 11 is wound around the outside of the heating component. The input port and the output port of the conveying coil 11 are respectively arranged on the tank body. The hydrogen production raw material enters the conveying coil 11 from the input port of the conveying coil 11. The tank body is filled with oil. The heating component 4 heats the oil in the tank body, and the oil then heats and vaporizes the hydrogen production raw material in the conveying coil 11. The vaporized hydrogen production raw material is transported from the output port of the conveying coil 11 to the converter for hydrogen production. The heating component 4 in the device is installed from the upper side of the tank body, which is convenient for installation and maintenance, and improves work efficiency. In addition, the heating component 4 is more convenient to install and seal from the upper side and has better sealing.

[0023] like Figure 2 As shown, in this embodiment, the tank body includes an evaporator 1 and a heating tank 2, and the evaporator 1 and the heating tank 2 are respectively installed with a group of heating components 4, and the heating components 4 of the evaporator 1 and the heating tank 2 are both installed from the tank opening on the upper side, and the output port of the conveying coil 11 in the evaporator 1 is connected with the input port of the conveying coil 11 in the heating tank 2 through a connecting pipe 5, and the hydrogen production raw material enters the conveying coil 11 of the evaporator 1 from the input port of the conveying coil 11, and the hydrogen production raw material is gasified in the evaporator 1, and then enters the conveying coil 11 in the heating tank 2, and is heated again in the heating tank 2, and finally enters the converter from the heating tank 2.

[0024] In this embodiment, the evaporation tank 1 and the heating tank 2 are arranged side by side, and the outer sides of the evaporation tank 1 and the heating tank 2 are tightly connected. The evaporation tank 1 and the heating tank 2 are fixedly welded by a connecting block. The evaporation tank 1 and the heating tank 2 are arranged side by side, which can reduce the heat loss in the evaporation tank 1 and the heating tank 2. Support legs 6 are fixedly provided at the bottom of the evaporation tank 1 and the heating tank 2.

[0025] The temperature of the heating tank 2 will be a little higher, but the oil temperature close to the heating component 4 is higher than the oil temperature far away from the heating component 4, which will make the oil temperature in the heating tank 2 uneven. Therefore, the heating tank 2 in this embodiment is connected to a circulation pipeline 7, and both ends of the circulation pipeline 7 are connected to the heating tank 2. A circulation pump 8 is arranged on the circulation pipeline 7. The upper side of the circulation pipeline 7 is an oil outlet, and the lower side is an oil inlet. The circulation pump 8 draws out the oil in the heating tank 2 from the upper oil outlet, and then transports the oil back to the heating tank 2 from the lower oil inlet, so as to realize the circulation of the oil in the heating tank 2 and make the oil temperature in the heating tank 2 uniform.

[0026] like Figure 3As shown, the heating assembly 4 in the evaporation tank 1 includes an upper mounting assembly and an evaporation electric heating tube 9 in the tank, and the heating assembly 4 in the heating tank 2 includes an upper mounting assembly and a heating electric heating tube 10 in the tank, and a tank cover 3 is provided on the upper side of the mounting assembly. In the prior art, electric heating tubes are provided in the vaporizer and the superheater, but the electric heating tubes in the prior art are generally installed from the bottom, which makes the inspection, installation and sealing of the electric heating tubes very inconvenient, while the heating assembly 4 of the present application is installed from the upper side, but there is a problem of dry burning when installed from the upper side. Once the oil level in the tank drops, the uppermost side of the electric heating tube will dry burn. Therefore, the uppermost side of the evaporation electric heating tube 9 in the present embodiment is provided with a non-heating portion 901. Even if the oil level drops, there will be no problem of dry burning. At the same time, the oil expands due to heat. Therefore, if the oil in the tank body is filled up in a cooling environment, the oil will expand during heating. However, if the oil is not filled up directly, there will still be a certain problem of dry burning. Therefore, the tank body is connected to an oil replenishing pipeline, and the oil replenishing pipeline is connected to the expansion tank 12. When the oil in the tank body expands, it enters the expansion tank 12 through the oil replenishing pipeline.

[0027] The evaporation tank 1 and the heating tank 2 in the utility model are arranged side by side, and the evaporation tank 1 and the heating tank 2 are fixedly welded by a connecting block. The heating component 4 is installed from the tank mouth on the upper side of the tank body to the inside of the tank body, and the connection between the heating component 4 and the tank body is sealed, which is convenient for installation and maintenance, and improves work efficiency. The heating component 4 is more convenient to install and seal from the upper side and has a better seal. A non-heating portion 901 is provided on the upper side of the evaporation electric heating tube 9, so there will be no problem of dry burning even if the oil level drops.

[0028] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
