It is the metal powder that question response is first added into reaction solution mostly during existing hydrogen gas production measurement experiment
End, then again seals reaction vessel, and being so easily caused before sealed reaction vessel just has gas effusion.The present embodiment
Metal/water reaction hydrogen manufacturing experimental provision and collection method, the metal dust of question response added after reaction vessel, and sealing reaction is held
Device, is then turned on magnetic valve 7 and adds reaction solution, the addition of reaction solution is controlled by control cabinet 12, and its principle is by 1#
The liquid level change of the monitoring solution storage of pressure transmitter 13 case 9, it is artificial that reaction solution addition is set, when 1# pressure transmitters 13
Detect when pressure value just reaches setting value equal to reaction solution addition remaining reaction solution liquid level institute in solution storage case 9
Corresponding critical pressure, then trigger the closing motion of magnetic valve 7, and then stops the addition of reaction solution, realizes determining for reaction solution
Amount addition.When the process further aspect avoids addition metal simultaneously and reaction solution, due to not timely sealed reaction vessel
Caused gas escapes problem, on the other hand can accurately measure when reaction to decomposition induction time when having gas generation
Between, it is easy to further investigate course of reaction.
The amount of the metal of question response and reaction solution can not accomplish quantitative control and reaction temperature in existing course of reaction
It is uncontrollable, it is unfavorable for carrying out reaction the intensity of quantitative study and control reaction；The metal of the present embodiment/water reaction hydrogen manufacturing experiment
