Description
Technical Field
The invention relates to the technical field of hydrogen production, in particular to a high-performance reforming reactor.
Background
Hydrogen energy is a clean secondary energy source. In recent years, as the development of hydrogen energy application technology has matured and the global pressure to cope with climate change has increased continuously, the development of hydrogen energy industry has been attracting attention in countries around the world, and developed countries such as the united states, germany, japan, etc. have successively increased the development of hydrogen energy industry to a national energy strategy. In addition, the state of innovation of the hydrogen energy and the fuel cell technology is in the innovation action plan of the energy technical revolution, which marks that the hydrogen energy industry is brought into the national energy strategy of China, and the hydrogen fuel cell can efficiently and cleanly convert chemical energy into electric energy directly, is a more advanced conversion technology than a conventional heat engine, and brings great opportunity for the innovation of energy power due to the rapid development of the fuel cell technology.
Along with the development of technology, requirements on energy and standby batteries are more and more strict, and the clean, noise-free and interference-free energy or standby batteries are urgently needed in various fields such as mobile communication base stations, micro stations, emergency vehicles, airport tractors, logistics vehicles, hospital power supply, data center power supply, military and the like. 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 for generating power after hydrogen production by using methanol water is more and more emphasized, so that an industry for generating power after hydrogen production by using methanol water is created.
The methanol-water hydrogen production process needs high-temperature reforming, so that the reforming reactor is a core component of the methanol-water hydrogen production process. The principle of the hydrogen production process by methanol water is as follows: the methanol water fuel is pressurized and gasified by heat absorption, then enters a reforming chamber to carry out reforming reaction together with a catalyst, so as to obtain hydrogen (hydrogen rich) rich in impurities, and the hydrogen passes through a purifier to generate high-purity hydrogen (H) reaching 99.99 percent 2 ) And the CO content is less than or equal to 1 ppm). The hydrogen is converted into normal temperature through heat exchange, and enters a galvanic pile through decompression to generate electrochemical reaction, so as to generate electric energy. The hydrogen production reaction mechanism is as follows:
CH 3 OH(g)→CO+2H 2 ，Δ＝-90.64KJ/mol，
CO+H 2 O(g)→CO 2 +H 2 ，Δ＝-41.00KJ/mol。
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 conventional reforming reactor is that the temperature reaches the reforming reaction temperature by using electric heating, and the purified split gas is introduced into combustion, so that the design has the defects of consuming a large amount of electric energy, being influenced by the fact that the electric heating cannot be performed at a high power (the electric power generation is performed under the condition of lack of electricity), and being limited in cost, so that the reforming hydrogen production device reaches the reforming reaction temperature by using the electric heating mode under the conventional temperature, the cold start time is generally more than 10 hours, and the hydrogen purifier used in the conventional reforming hydrogen production device has the limit of the service life of the cold start times, thereby influencing the service life of the whole equipment. The second design idea of the traditional reforming reactor adopts a cylindrical reforming chamber, and a palladium pipe is arranged in the cylindrical reforming chamber, and the flame is utilized to directly heat the reforming chamber and the palladium pipe, so that the defects are uneven heating, the heat balance cannot be controlled, the performance of the palladium pipe is reduced and the service life is short under the condition that the catalyst efficiency is low, and the palladium pipe can be rapidly cold started (30-60 minutes), but the palladium pipe has more than 10 cold start service lives and cannot be used as an instant standby 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 defects of complex work, high labor cost and disposability are overcome. The four design ideas of the traditional reactor adopt a palladium membrane purification mode, and the defects are that the cost is extremely high, the cost is 80 percent of the cost of the whole reactor, the purification purity and efficiency of the traditional reactor are not broken through compared with the palladium tube type, the heating of the purifier is carried out by the heat conduction and electric heating of the whole reactor, especially the electric heating is required to be continuous, and the internal consumption is extremely high.
