Description
Technical Field
The utility model relates to a hydrogen manufacturing technical field, concretely relates to high performance reforming reactor.
Background
Hydrogen energy is a clean secondary energy source. In recent years, with the gradual maturity of the development of hydrogen energy application technology and the continuous increase of global pressure to cope with climate change, the development of the hydrogen energy industry is receiving attention in countries around the world, and developed countries such as the united states, germany and japan successively promote the development of the hydrogen energy industry to the high degree of the national energy strategy. And the innovation of hydrogen energy and fuel cell technology is listed in the innovation action plan of energy technology revolution in China, the hydrogen energy production is marked to be incorporated into the energy strategy of China, the hydrogen fuel cell can efficiently and cleanly convert chemical energy into electric energy, the technology is a more advanced conversion technology than a conventional heat engine, the rapid development of the fuel cell technology brings a great opportunity for the revolution of energy power.
Furthermore, with the development of science and technology, the requirements for energy sources and backup batteries are becoming more and more strict, and for example, in many fields such as mobile communication base stations, micro-stations, emergency vehicles, airport tractors, logistics vehicles, hospital backup, data center backup, military and the like, a clean, noiseless and interference-free energy source or backup battery is urgently needed. However, if hydrogen is directly used for power generation, safety technical bottlenecks such as 'manufacturing, storage and transportation' exist, and under the background, a technical route of power generation after hydrogen production by methanol water is more and more emphasized, so that an industry which produces power after hydrogen production by methanol water is produced.
The hydrogen production process of methanol-water needs high-temperature reforming, so the reforming reactor is a core component of the hydrogen production process of methanol-water. The principle of the hydrogen production process by methanol water is as follows: after being pressurized and gasified by absorbing heat, the methanol-water fuel enters a reforming chamber and enters with a catalystReforming reaction is carried out to obtain hydrogen rich in impurities (hydrogen rich), and the hydrogen passes through a purifier to generate high-purity hydrogen (up to 99.99 percent of high-purity hydrogen (H)2) And the CO content is less than or equal to 1 ppm). The hydrogen is changed into normal temperature through heat exchange, enters the electric pile through decompression to generate electrochemical reaction, and generates electric energy. The hydrogen production reaction mechanism is as follows:
CH3OH(g)→CO+2H2，Δ＝-90.64KJ/mol，
CO+H2O(g)→CO2+H2，Δ＝-41.00KJ/mol。
wherein, the hydrogen production reaction is a strong endothermic reaction, and heat needs to be continuously supplied to maintain the reaction. One of the design ideas of the traditional reforming reactor is to utilize electric heating to enable the temperature to reach the temperature of reforming reaction, and then purified shunt gas is used for introducing combustion, the design has the defects of consuming a large amount of electric energy, being influenced by incapable high-power electric heating (generating electricity under the condition of power shortage) and cost limitation, so that the temperature of reforming hydrogen production device reaching the reforming reaction by utilizing the electric heating mode at the conventional temperature belongs to cold start, the cold start time generally exceeds 10 hours, and a hydrogen purifier used in the existing reforming hydrogen production device has the limitation of the service life of cold start service times, further influences the service life of the whole device, and in order to avoid cold start equipment, the reforming hydrogen production device has to be always under the hot standby condition under the general condition, and a large amount of electric energy can be consumed for a long time. The second design concept of the conventional reforming reactor is to use a cylindrical reforming chamber, place the palladium tube in the cylindrical reforming chamber, and directly heat the reforming chamber and the palladium tube by using flame, which has the disadvantages of uneven heating, uncontrollable heat balance, low catalyst efficiency, reduced performance of the palladium tube, short service life, and rapid cold start (30-60 minutes), but the palladium tube has a cold start life of only 10 times and cannot be used as a real-time backup battery. The third design idea of the traditional reactor is to ensure that the reforming chamber and the reforming reaction coil are heated uniformly by adopting an aluminum casting process, and the traditional reactor has the defects of complex working, high labor cost and one-off property. The fourth design idea of the traditional reactor adopts a palladium membrane purification mode, and has the defects of extremely high cost which accounts for 80 percent of the cost of the whole reactor, no breakthrough exists in the purity and efficiency of purification compared with a palladium tube type, and the heating of the purifier depends on the heat conduction and electric heating of the whole reactor, particularly the electric heating must be continuous, so that the internal consumption is overhigh.
