Hydrogen production device for producing pure hydrogen from organic fuel

A hydrogen production device related to producing pure hydrogen from organic fuel, which can generate heat energy required for producing hydrogen-containing gas in a flameless manner, and purify and methanize the hydrogen-containing gas to obtain pure hydrogen gas.

A generator is a device that converts kinetic energy or other forms of energy into electrical energy. A general generator converts the energy contained in various primary energy sources (such as water power, coal, fuel oil, wind energy, atomic energy, geothermal energy, tides) into mechanical energy, and then converts it into electrical energy through the generator and sends it through the transmission and distribution network. Go to various places where electricity is used.

Generators are used as backup power sources in general places. Among them, internal combustion generators are the most commonly used generators. When the internal combustion generator is working, it will produce noise and emit incomplete combustion exhaust gas, polluting the air quality of the working environment.

A fuel cell is a power generation device that mainly uses oxygen or other oxidants to perform redox reactions to convert chemical energy in fuel into electrical energy. The most common fuel is hydrogen. Hydrogen can come from any hydrocarbon that can decompose into hydrogen gas, such as natural gas, alcohol, and methane. Fuel cells are different from primary batteries. Their advantage lies in the stable supply of oxygen and fuel sources, that is, they can continuously provide stable power until the fuel is exhausted. Unlike ordinary non-rechargeable batteries, They are thrown away after use, and unlike rechargeable batteries, they must be recharged after use. Therefore, after being connected in series through battery stacks, they can even become a power generation device with a power generation capacity of one million watts (MW). Therefore, as long as pure hydrogen can be produced and supplied to the fuel cell power generation device to generate electrical energy, and then undergo voltage stabilization, power storage, and power supply, the required power can be provided to the site without interruption of power supply.

Please refer to Picture 1 ~ Picture 2. The hydrogen production device disclosed in this invention for producing pure hydrogen from organic fuel includes: a reactor 10, an air input device 20, a fuel input device 30, a fuel water input device 40, and a hydrogen purification device 50. A first hydrogen transport pipeline 51, a second hydrogen transport pipeline 52, a third hydrogen transport pipeline 53, and a hydrogen storage barrel 60. The reactor 10 includes a heating zone 11 , a preheating zone 12 , a reforming zone 13 , and a methanation zone 14 . A heating catalyst is provided in the heating zone 11 . The heating catalyst may be a platinum catalyst. The preheating zone 12 and the reforming zone 13 are connected. A reforming catalyst is provided in the reforming area 13 . A methanation catalyst is provided in the methanation zone 14 .

This invention mainly sends organic fuel (such as methanol) into the heating zone 11 in the reactor 10 to generate heat energy and increase the overall temperature of the reactor 10 . Organic fuel water (e.g. For example: methanol aqueous solution) is sent into the preheating zone 12 and the reforming zone 13 of the reactor, and hydrogen-containing gas is generated through molecular recombination. The hydrogen purification device 50 can screen out hydrogen and carbon monoxide from the hydrogen-containing gas, and send them into the methanation zone 14 of the reactor 10 through the second hydrogen transport pipeline 52 to obtain pure hydrogen through methanation, and into the hydrogen storage barrel 60 .

The air input device 20 includes an air pump 22 and an air input pipeline 21 . The air input pipeline 21 is connected with the heating zone 11 in the reactor 10 . When the air pump 22 is activated, oxygen-containing air can be sent into the heating zone 11 . The fuel input device 30 includes: a fuel storage tank 31 and a fuel input pipeline 32 . Organic fuel (for example, methanol) can be stored in the fuel storage barrel 31 . The fuel input line 32 is provided with a first liquid pump 33, a first electric valve 34, and a first check valve 35. The end of the fuel input pipeline 32 is connected with the air input pipeline 21 . When the first liquid pump 33 is activated, the organic fuel can be injected into the air input pipe 21 , so that the organic fuel and air can be sent into the heating zone 11 at the same time. An exhaust pipe 101 is provided at the top of the heating zone 11 to discharge exhaust gas containing carbon dioxide. The first check valve 35 can prevent the oxygen-containing gas from flowing backward.

In the above, the liquid organic fuel injected into the air input pipe 21 is formed into fine droplets due to high-pressure injection, and then is crushed into finer droplets due to impact on the inner wall of the air input pipe 21. It will attach to the oxygen-containing gas, causing the oxygen-containing gas to mix with the liquid organic fuel to form oxygen-containing gas. The oxygen-containing gas is fed into the heating zone 11 of the reactor 10 via the air input pipe 21 . The oxygen-containing gas produces exothermic oxidation under the action of the heating catalyst, which is a flameless heating effect, thereby increasing the overall temperature of the reactor 10 and producing waste gas containing carbon dioxide.

The reactor 10 is provided with a temperature sensor 102 and an electric heater 103. The outside of the reactor is covered with a thermal insulation layer (not shown in the figure). When the temperature sensor 102 detects When the temperature of the reactor 10 is too low for the heating catalyst to take effect, the microprocessor 70 of an electrical device (not shown in the figure) will signal the electric heater 103 to operate to heat the reactor 10 . When the temperature of the reactor 10 rises enough to allow the heating catalyst to take effect, the microprocessor 70 will signal the first liquid pump 33, the first electric valve 34, and the air pump 22 to operate simultaneously; at the same time, it will signal the electric heater. 103 stops moving.

The fuel water input device 40 includes: a fuel water storage tank 41 and a fuel water input pipe 42 . Organic fuel water can be stored in the fuel water storage barrel 41 .

The end of the fuel water input pipeline 42 is connected to the preheating zone 12 of the reactor 10 so that the organic fuel water can be sent into the preheating zone 12 for preheating. The preheated and vaporized organic fuel water in the preheating zone 12 can be sent to the reforming zone 13 for molecular recombination to generate hydrogen-containing gas. The fuel water input line 42 flows through a first heat exchanger 45 and a second heat exchanger 46 . The second check valve 44 can prevent reverse flow of the organic fuel water.

The working temperature of the reforming catalyst in the reforming zone 13 is 220°C. The reforming catalyst may be a copper-zinc catalyst. When the temperature sensor 102 detects that the temperature of the reactor 10 is lower than 220° C., the microprocessor 70 will not signal the second liquid pump 43 to operate. During this process, the reactor 10 can preheat the organic fuel water staying in the preheating zone 12 while being continuously heated. When the temperature sensor 102 detects that the temperature of the reactor 10 reaches or exceeds 220°C, the microprocessor 70 signals the second liquid pump 43 to operate to deliver organic fuel water to the preheating chamber of the reactor 10 Within zone 12. At the same time, the gaseous organic fuel water that has been preheated to a temperature higher than 220°C and vaporized in the preheating zone 12 is pushed to the reforming zone 13 .

The hydrogen-containing gas must be cooled after being sent out of the reactor 10 . The hydrogen-containing gas will first pass through the first heat exchanger 45 and perform heat exchange with the low-temperature organic fuel water to lower the temperature and simultaneously increase the temperature of the organic fuel water. The heat dissipation device 511 of the first hydrogen gas delivery pipeline 51 can further reduce the temperature of the hydrogen-containing gas.
