Description

Technical Field

[0001] This utility model relates to a methanol-to-hydrogen reactor, specifically a water-based fuel hydrogen generator. Background Technology

[0002] Hydrogen energy is a green and clean energy source with wide applications in various fields. Hydrogen gas can be produced from hydrogen compounds. Methanol-to-hydrogen is one such method, and methanol steam reforming is a commonly used method due to its high hydrogen content. The methanol steam reforming method involves mixing methanol and deionized water to form a water-based fuel, which is then introduced into a reactor to react and produce hydrogen and other substances. This reaction is strongly endothermic and requires external heat. Currently, a catalyst is typically added to the reforming reactor. The catalyst promotes the hydrogen production reaction, allowing it to proceed efficiently at relatively low temperatures (typically 200-300℃).

[0003] However, existing catalysts used in methanol steam reforming for hydrogen production are expensive and prone to poisoning, resulting in high operating costs for reforming reactors. Therefore, there is an urgent need for a catalyst-free water-based fuel hydrogen generator. Utility Model Content

[0004] The purpose of this invention is to provide a water-based fuel hydrogen generator to solve the problem of high operating costs of reforming reactors in existing methanol steam reforming hydrogen production methods.

[0005] This utility model is implemented as follows: A water-based fuel hydrogen generator includes a frame, a generator, a feed pump, a feed pipe, and a discharge pipe; the frame is used to support and install the generator; the feed pump is connected to the generator through the feed pipe and is used to pump a mixture of methanol and deionized water to the generator; the generator includes a double-layer coil, an insulation layer, and an electromagnetic induction coil; the inlet of the double-layer coil is connected to the feed pipe, the outlet of the double-layer coil is connected to the discharge pipe, the insulation layer covers the outside of the double-layer coil, and the electromagnetic induction coil is wound around the outside of the insulation layer, and the electromagnetic induction coil is used to heat the double-layer coil.

[0006] As a further improvement to the water-based fuel hydrogen generator of this utility model, the double-layer coil includes an inner spiral coil and an outer spiral coil. The inner spiral coil is located inside the outer spiral coil and the inner spiral coil and the outer spiral coil are coaxially arranged. A coil inlet is provided at the top of the inner spiral coil and the coil inlet is connected to the feed pipe. The bottom of the inner spiral coil is connected to the bottom of the outer spiral coil. A coil outlet is provided at the top of the outer spiral coil and the coil outlet is connected to the discharge pipe.

[0007] As a further improvement to the water-based fuel hydrogen generator of this utility model, the coil inlet and the feed pipe are connected by a flange, and a flange is provided at the port of the discharge pipe.

[0008] As a further improvement to the water-based fuel hydrogen generator of this utility model, the total height and pitch of the inner spiral coil and the outer spiral coil are the same.

[0009] As a further improvement to the water-based fuel hydrogen generator of this utility model, baffles are respectively provided at the upper and lower ends of the double-layer coil.

[0010] As a further improvement to the water-based fuel hydrogen generator of this utility model, the frame is a frame structure, a box is provided on the outside of the frame, and a box door is provided on the front side of the frame.

[0011] As a further improvement to the water-based fuel hydrogen generator of this utility model, an electromagnetic heating controller is provided on the frame, and the electromagnetic heating controller is electrically connected to the electromagnetic induction coil.

[0012] The generator of this invention employs a double-layer coil structure and uses an electromagnetic induction coil to heat the double-layer coil structure. The electromagnetic heating controller rectifies the AC mains power into DC power, and then converts the DC power into high-frequency AC power. When the rapidly changing high-frequency current flows through the electromagnetic induction coil, it generates a rapidly changing alternating magnetic field. The metal double-layer coil cuts through the alternating magnetic field lines, thereby heating the double-layer coil. The electromagnetic induction coil can heat the double-layer coil to a high temperature (above 800℃), and when a mixture of methanol and water enters the double-layer coil, it vaporizes and undergoes a high-temperature methanol-water vapor reforming reaction to produce hydrogen.

[0013] This invention uses electromagnetic induction coil heating to raise the temperature of the double-layer coil, enabling the methanol-water vapor reforming hydrogen production reaction without the need for a catalyst. Since the mixture of methanol and water first passes through the inner spiral coil and then through the outer spiral coil, the reactants travel a long distance within the coil, allowing the methanol-water vapor reforming hydrogen production reaction to be fully and completely carried out under continuous high temperature.

[0014] The double-layer coil structure fully utilizes the alternating magnetic field generated by the electromagnetic induction coil, enabling rapid heating to reach the required temperature. Furthermore, the insulation layer protects the generator, reducing heat loss and resulting in low energy consumption during continuous operation. Since this generator does not require a catalyst and eliminates the need for subsequent replacement of poisoned catalysts, its production and operating costs are low. Attached Figure Description

[0021] Example 1 The water-based fuel hydrogen generator 2 in this embodiment mainly includes a frame 1, a generator 2, a feed pump 3, a feed pipe 4, and a discharge pipe 5.

[0022] The frame 1 is a frame structure, which is assembled from square tubes. Side plates are provided on the outside of the frame 1 to form a box. A box door is installed on the front side of the frame 1. The generator 2 and the feed pump 3 are installed inside the frame 1.

[0023] The frame 1 is divided into upper and lower parts. The generator 2 is fixedly installed on the upper part of the frame 1, while the electromagnetic heating controller is fixedly installed on the lower part of the frame 1. The position of the feed pump 3 is determined as needed. In this embodiment, the feed pump 3 is installed on the lower part of the frame 1.

[0024] Feed pump 3 is connected to the inlet of generator 2 via feed pipe 4. The inlet of feed pump 3 extends outside the tank via a pipeline for connection to an external container. The external container supplies feed pump 3 with a certain proportion of methanol and water mixture, i.e., methanol-water-based fuel. After feed pump 3 starts, it delivers the methanol and water mixture to generator 2 through feed pipe 4.

[0025] The outlet of generator 2 is connected to a discharge pipe 5, which extends outside the housing and is used to output a mixture of hydrogen and other gases.

[0026] The generator 2 includes a double-layer coil 21, an insulation layer 22, and an electromagnetic induction coil 23. The inlet of the double-layer coil 21 is connected to the feed pipe 4, and the outlet of the double-layer coil 21 is connected to the discharge pipe 5. The insulation layer 22 covers the outside of the double-layer coil 21, and the electromagnetic induction coil 23 is wound around the outside of the insulation layer 22.

[0027] The electromagnetic induction coil 23 is electrically connected to the electromagnetic heating controller, which rectifies the AC mains power into DC power and then converts the DC power into high-frequency AC power. When a rapidly changing high-frequency current flows through the electromagnetic induction coil 23, it generates a rapidly changing alternating magnetic field. The double-layered metal coil 21 cuts through the alternating magnetic field lines, thereby heating the double-layered coil 21. Electromagnetic induction can quickly heat the double-layered coil 21 to a high temperature and has a higher heat conversion efficiency compared to other heating methods.

[0028] Baffles 24 are provided at the upper and lower ends of the double-layer coil 21, and the insulation layer 22 is wrapped between the baffles 24 and on the upper and lower sides of the baffles 24. The insulation layer 22 wraps the entire double-layer coil 21, which can reduce the heat loss of the double-layer coil 21 after heating.

[0029] The electromagnetic induction coil 23 is wound around the outside of the insulation layer 22 in one direction from bottom to top or from top to bottom. The electromagnetic induction coil 23 can be fixed to the outside of the insulation layer 22 with high-temperature resistant adhesive. The two ends of the electromagnetic induction coil 23 are electrically connected to the electromagnetic heating controller through wires. The electromagnetic heating controller is existing technology and will not be described in detail here.

[0030] The double-layer coil 21 includes an inner spiral coil 211 and an outer spiral coil 212 nested together. The inner spiral coil 211 is located inside the outer spiral coil 212 and the inner spiral coil 211 and the outer spiral coil 212 are coaxially arranged.

[0031] A coil inlet 213 is provided at the top of the inner spiral coil 211, which is connected to the feed pipe 4. The bottom of the inner spiral coil 211 is connected to the bottom of the outer spiral coil 212. A coil outlet 214 is provided at the top of the outer spiral coil 212, which is connected to the discharge pipe 5.

[0032] The mixture of methanol and water enters through the coil inlet 213 and flows downwards through the inner spiral coil 211. After reaching the bottom of the inner spiral coil 211, it enters the bottom of the outer spiral coil 212, then flows through the outer spiral coil 212 again. Finally, the reaction product exits from the top coil outlet 214. The entire double-layer coil 21 has a compact structure and a long tube length, allowing the mixture to react fully within the coil.

[0033] A flange is provided at the end of the coil inlet 213. The coil outlet 214 and the discharge pipe 5 are an integral structure. A flange is also provided at the port of the discharge pipe 5. After the double-layer coil 21 is manufactured, it can be installed as a whole on the frame 1.

[0034] The inner spiral coil 211 and the outer spiral coil 212 have the same total height and pitch, while the total height, pitch, and diameter of the double-layer coil 21 are determined as needed.

[0035] Baffles 24 are provided at the upper and lower ends of the double-layer coil 21 so that the insulation layer 22 wrapped around both sides of the double-layer coil 21 can form a sealed insulation structure on the outside of the double-layer coil 21.

[0036] Example 2 In this embodiment, a temperature sensor is added based on the first embodiment. The temperature sensor passes through the baffle 24 and is inserted into the generator 2. The temperature sensor can detect the temperature inside the generator 2. The temperature sensor is connected to the electromagnetic heating controller through a wire. The electromagnetic heating controller controls the change of high-frequency current through the temperature signal detected by the temperature sensor to maintain the stability of the temperature inside the generator 2.

[0037] The frame 1 is also equipped with a power connection port, control panel, gear switch, etc., for setting temperature, feeding speed, etc.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
