Water filling, operation are cumbersome.The metal of the present embodiment/water reaction hydrogen manufacturing experimental provision and collection method, water is passed through on gauge line 1
In portion opening injection gauge line 1 and storage tank 2, it can be seen from law of connected vessels, the now water level of gauge line 1 and storage tank 2 one
Cause, can according to be actually needed determine experiment needed for height of water level.In experimentation, hydrogen caused by reaction can enter storage tank 2,
And the water of equal volume is drained into gauge line 1, now the water level of gauge line 1 is higher than storage tank 2；After one group of experiment terminates, open
Metal dust opening on three mouthfuls of conical flasks 5, storage tank 2 communicate with air, the rising of groundwater level of storage tank 2 and with gauge line 1
Water level is consistent again, can proceed with next group of experiment test, without repeating water filling.By the present invention improvement, in experiment only
Need a water filling just can realize multiple test, avoiding gas collection measuring cylinder in current hydrogen gas production measurement experiment needs water filling repeatedly
Troublesome operation process.
It is the metal powder that question response is first added into reaction solution mostly during existing hydrogen gas production measurement experiment
End, then reaction vessel is sealed again, so doing easily causes just have gas effusion before sealed reaction vessel.The present embodiment
Metal/water reaction hydrogen manufacturing experimental provision and collection method, after the metal dust of question response adds reaction vessel, sealing reaction is held
Device, it 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 to pass through 1#
Pressure transmitter 13 monitors the liquid level change of solution storage case 9, artificial to set reaction solution addition, 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 the closing motion of magnetic valve 7 is triggered, and then stop the addition of reaction solution, realize determining for reaction solution
Amount addition.When the process further aspect avoids while adds metal with reaction solution, due to not timely sealed reaction vessel
Caused gas escapes problem, when on the other hand can accurately measure since 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
Device and collection method, the addition of reaction solution can realize quantitative control by control cabinet 12, and reaction temperature can pass through temperature
Controller 11 and constant water bath box 14 realize control, so as to be advantageous to that the intensity of quantitative study and control reaction is carried out to reaction.
