Domain.It is the general chemical hydrogen manufacturing mode of meteorological field that ferrosilicon, which reacts hydrogen manufacturing with sodium hydroxide solution, by ferrosilicon powder, piece alkali when use
It mixes and is put into a big hydrogen manufacturing cylinder with water, react after shaking and generate hydrogen.The reaction of the hydrogen production process is short several
It is completed in minute, releases a large amount of heat, for bottle body temperature up to hundreds of degree, internal pressure reaches more than ten megapascal, exists very big
Security risk and it is necessary to place a few hours make hydrogen_cooling after could use.In view of hydrogen production process can discharge a large amount of heat
Amount, Authorization Notice No. are a kind of portable hydrogen-hydrogen-feeding system disclosed in the patent document of CN204022465U in addition to device for producing hydrogen,
It is also provided with the cooling back installation of coolant liquid heat dissipation, due to higher containing more impurity and temperature in hydrogen obtained, this is
System is equipped with cooled filtrate, removes impurity and steam in gas.
To eliminate reformation hydrogen production, structure is complicated for water electrolysis hydrogen production etc., cannot it is portable, energy consumption is high, hydrogen manufacturing starts that speed is slow etc. to be lacked
It falling into, technology of the invention provides a kind of portable chemical hydrogen manufacturing tank, and such portable chemical hydrogen manufacturing tank volume is smaller, it is easy to portable,
Now-making-now-using can be met when hydrogen manufacturing, while such portable chemical hydrogen manufacturing tank is not only suitable for producing a small amount of hydrogen, while can incite somebody to action
Multiple portable chemical hydrogen manufacturing tanks are connected by gas piping, larger amount of hydrogen are produced, due to each hydrogen manufacturing in the hydrogen production process
The heat that tank generates can disperse in time, and without the concern for heat dissipation problem, overall structure is simple, and easy to use, hydrogen manufacturing can show
It makes current.
