Embodiment 1

[0043] Embodiment 1: Utilize solar energy to produce hydrogen

[0044] First, the basic principle of hydrogen production: the reaction of decomposing water into hydrogen and oxygen cannot proceed spontaneously, but mainly through the following four processes to chemically convert water into a compound that is easy to be photolyzed, and decompose it with light Among them, the compounds that are difficult to pyrolyze complete a hydrogen production cycle, and finally realize the forward reaction.

[0045] 1) Manufacture of salt: 6I 2 +6Ca(OH) 2 =5CaI 2 +Ca(IO 3 ) 2 ↓+6H 2 o

[0046] 2) Splitting of water:

[0047] 3) Release hydrogen:

[0048] 4) Release oxygen:

[0049] Second. The main production process of hydrogen production:

[0050] The main process of producing hydrogen includes: ① solar energy to produce water vapor; ② preparation and separation of salt; ③ moderate temperature hydrolysis of calcium iodide solution and preparation of hydroiodic acid; ④ prepara...

Embodiment 2

[0119] Utilize solar energy to produce the photolysis device that hydrogen methanol is useful, i.e. photolysis pool (7), combine with solar heat collector (12), promptly photolysis pool (7) is on, heat collector (12) is below, light The bottom plate of solution pond (7) is light-transmitting glass, is parallel with heat collector (12) upper panel light-transmitting glass and has heat insulation interval. The two are combined to make the sunlight that cannot be photolyzed enter the absorber of the heat collector (12) and become heat energy, thereby improving the utilization rate.

Embodiment 3

[0121] In the method of utilizing solar energy to produce hydrogen methanol, the water vapor produced by the solar heat collector (12) is first input into the steam turbine generator set to generate electricity, and then enters the evaporator (5). The electric energy produced by the generating set passes through the electric furnace to provide heat for the calciner (2) to calcinate the calcium iodate. Moreover, when there is no sunlight, the electric light source composed of high-brightness light-emitting diodes is powered to maintain the photolysis reaction, so that the whole process continues uninterrupted.

Description

Technical field [0001] The invention relates to the field of solar energy utilization and chemical industry, in particular to a method for utilizing solar energy to produce hydrogen methanol by converting solar energy into chemical energy and realizing the industrialized production of hydrogen methanol. It also includes the solar photolysis device used in this method. Background technique [0002] As we all know, the energy crisis in the world today. Conventional energy sources—coal, oil, and natural gas are non-renewable energy sources that are increasingly depleted. Utilizing petroleum and natural gas as raw materials to produce motor oil is far from meeting the needs of the growing motor vehicles. Now people are looking for substitutes for motor oil, the simplest of which is methanol. Methanol is a liquid fuel, which is easy to use and store, and can replace gasoline. At the same time, it is a basic chemical raw material with huge social value. Hydrogen is a gaseous fu...
