The principle of work that the utility model is implemented is as follows:
Pull down inflator 2, make the supply opening of feed flow bottle cap 11 open, in supplying bottle 1, the water of proper ratio, medicine is dropped into (as sheet alkali again by feed flow bottle cap 11, main component NaOH), be stirred to after dissolving completely and again inflator 2 loaded onto again, and open reaction bottle cap 31, reaction raw materials particle (as aluminium, silicon) is dropped in reaction flask 3, make it to fall on dividing plate 4, again reaction bottle cap 31 is covered subsequently, air outlet valve 32 is remained on open mode, then in liquid collecting cooling bottle 5, pours water coolant into, cover liquid collecting bottle cap subsequently;
Then piston rod 21 is twitched up and down, when piston rod 21 moves up, piston 22 is close to the jacking block 24 with through hole, now the through hole of outside air in piston on annular distance and jacking block 24 enters piston lower portion, and the air in supplying bottle is blocked by check valve 25 and can not be entered the external world, when piston rod 21 moves down, pushing block 23 is close to piston 22, thus annular distance in piston is blocked, the air of piston lower portion is made to be pushed into supplying bottle 1 by check valve 25, and so forth, until the liquid in supplying bottle 1 all flows into reaction flask 3 through feed pipe 12 under gas pressure, in this process after the liquid flowing into reaction flask 3 times sub-chambeies covers dividing plate 4, just with the reaction raw materials particle generation chemical reaction on dividing plate 4, generate hydrogen,
The chemical equation of sheet alkali solvent and aluminum particulate hydrogen making is utilized to be:
2Al+2NaOH+2H
2O=2NaAlO
2+3H
2↑；
The chemical equation of sheet alkali solvent and silicon grain hydrogen making is utilized to be:
Si+2NaOH+ H
2O=Na2SiO
3+2 H
2↑；
The hydrogen being mingled with large quantity of moisture that reaction produces enters spiral coil cooling tube 6 by inlet pipe 9, owing to there is the water coolant (such as mixture of ice and water) of low temperature in liquid collecting cooling bottle 5, after the cooling water temperature condensation that the liquid taken out of by hydrogen by the violent chemical reaction of reaction flask inside and part water vapour are cooled around coil pipe 6, be collected in liquid collecting cooling bottle 5, being entered into from liquid collecting cooling bottle 5 hydrogen being still mingled with water vapour out by pipe connecting 8 is equipped with in the drying bottle 7 of siccative, through the drying of drying bottle 7, the purity of hydrogen, degree of drying gets a promotion again, finally export 71 by the dry gas on drying bottle 7 to discharge,
The air outlet valve 32 at off-response bottle 3 top, the i.e. output of interruptible price hydrogen, again open the air outlet valve 32 at reaction flask 3 top, can recover the output of hydrogen;
When interrupting the time of hydrogen output than when continuing longer, chemical reaction in reaction flask is also carrying out, hydrogen also produces in continuation, pressure in reaction flask 3 on liquid level is constantly increased, when after the pressure that the pressure on reaction flask liquid level is greater than on supplying bottle liquid level, liquid in reaction flask 3 then can be pushed back supplying bottle 1, when the liquid level in reaction flask 3 is close to dividing plate 4 upper surface, due to reacting material liquid (sheet alkali solvent) and reaction raw materials particle (aluminium, silicon) no longer contact, chemical reaction also stops immediately voluntarily, if cause supplying bottle 1 internal pressure excessive in this process, then the safety valve 13 on supplying bottle 1 top is opened automatically, partial air in release supplying bottle, until all pushed back supplying bottle 1 higher than the liquid on dividing plate 4 in reaction flask 3.
When needing to give vent to anger again after the time that interruption hydrogen exports is longer, open the air outlet valve 32 at reaction flask top, because the pressure in reaction flask 3 is lower than the pressure in supplying bottle 1, liquid in supplying bottle 1 reenters in reaction flask 3, when the liquid in reaction flask 3 covers dividing plate 4 upper surface, because reacting material liquid (sheet alkali solvent) contacts again with reaction raw materials particle, chemical reaction is restarted, and hydrogen regenerates;
When needs are shut down; first the air outlet valve 32 at off-response bottle 3 top interrupts hydrogen output; and by safety valve 13 manual unlocking on supplying bottle 3 top; air in release supplying bottle 1; by the time after the chemical reaction in reaction flask 3 stops (namely reacting material liquid no longer contacts with reaction raw materials particle); whole device internal pressure is tending towards barometric point, is back to the liquid in supplying bottle 1 and the reaction raw materials particle that remains unreacted complete on dividing plate 4 can utilize again.
