Embodiment 1
As shown in figure 1, providing a kind of hydrogen production process the invention provides the present invention, the method is comprised the following steps：
Liquid metal and sealing fluid are sequentially loaded into reaction unit, sealing fluid lid is located on liquid metal, make liquid
The liquid level of metal is located at below aqueous solution pipeline, the liquid level of sealing fluid is located between Hydrogen Line and aqueous solution pipeline；
After aqueous solution pipeline in reaction unit to the aqueous solution is passed through, there is hydrolysis in the aqueous solution with liquid metal；
The hydrogen produced after hydrolysis in Hydrogen Line collects reaction unit.
Thus, when manufacture hydrogen is needed, the aqueous solution can be passed through in reaction unit by aqueous solution pipeline.Due to water-soluble
, more than the density of sealing fluid, therefore the aqueous solution can be directly through sealing fluid and liquid metal contacts and that hydrolysis occurs is anti-for the density of liquid
Hydrogen should be produced.Due to, the density very little of hydrogen, hydrogen can sequentially pass through the mixed of liquid metal and the aqueous solution under buoyancy
Liquid and sealing fluid are closed, and collection device is entered by Hydrogen Line.Wherein, the outlet of aqueous solution pipeline is immersed in sealing fluid
In, can both avoid liquid metal from being oxidized, hydrogen can be avoided compromised again.If this is because, the outlet of aqueous solution pipeline is set
Put more than the liquid level of sealing fluid, when the thinner thickness of sealing fluid, the aqueous solution under gravity, is fallen with certain speed
On sealing fluid, sealing fluid may be broken up and cause operative liquid metal to be oxidized；In addition, the hydrogen partial for producing can directly lead to
Cross aqueous solution pipeline and enter device for storing liquid, so as to cause the waste of hydrogen.If the outlet of aqueous solution pipeline is immersed in into liquid gold
In category, operative liquid metal and the hydrogen of aqueous solution generation into aqueous solution pipeline can be directly entered storage along aqueous solution pipeline
Liquid device, causes the waste of hydrogen.If in addition, be attached with the tube wall of aqueous solution pipeline can with the impurity of liquid reactant metal,
The purity of hydrogen will be influenceed.
Preferably, liquid metal is aluminum gallium alloy, aluminium mercury alloy or alkali metal.For example, can select the mass ratio of sodium and potassium

Preferably, sealing fluid is atoleine or anhydrous kerosene.
Preferably, the aqueous solution is water, acid solution or alkaline solution.
In addition, in hydrolysis reaction, agitating device stirring liquid metal and the aqueous solution.By agitating device specifying
Speed rotate, liquid metal can be made to be fully contacted with the aqueous solution, so improve the unit interval generation hydrogen amount.
Embodiment 2
As shown in Fig. 2 present invention also offers a kind of hydrogen manufacturing mechanism, the mechanism include the first valve 7, the second valve 10,
Hydrogen Line 8, aqueous solution pipeline 9, collection device 6, reaction unit 1 and device for storing liquid 4, the outlet of Hydrogen Line 8 is by the
One valve 7 is connected with collection device 6, import is plugged in reaction unit 1, and the import of aqueous solution pipeline 9 passes through the second valve 10
Connected with device for storing liquid 4, export and be plugged in reaction unit 1, the height of the import of Hydrogen Line 8 is higher than aqueous solution pipeline 9
The height of outlet.
Thus, when manufacture hydrogen is needed, the second valve 10 and the first valve 7 are opened successively, pass through the aqueous solution 5 water-soluble
Liquid pipe road 9 is passed through in reaction unit 1 there is hydrolysis with liquid metal 3.The hydrogen that hydrolysis is produced is under buoyancy
Collection device 6 is entered by Hydrogen Line 8.When the amounts of hydrogen in collection device 6 reaches demand, the second valve can be successively closed
10 and first valve 7.Further, since height of the height of the import of Hydrogen Line 8 higher than the outlet of aqueous solution pipeline 9.When

The liquid level of sealing fluid 2 is located between Hydrogen Line 8 and aqueous solution pipeline 9, and the import for being equivalent to Hydrogen Line 8 is located at sealing fluid
More than 2 liquid level, the outlet of aqueous solution pipeline 9 is immersed in sealing fluid 2.
In addition, the import of aqueous solution pipeline 9 can be plugged in the bottom of device for storing liquid 4.So set and be advantageous in that：One side
Face, due to bigger apart from the top of device for storing liquid 4 more far water pressure, so as to promote the aqueous solution 5 to pass through aqueous solution pipeline 9 using hydraulic pressure
In inflow reaction unit 1；On the other hand, can avoid the aqueous solution 5 of the bottom deposit of device for storing liquid 4 can not be discharged and cause wave
Take.
Wherein, also including liquid pump, liquid pump is serially connected on aqueous solution pipeline 9, thinks that the aqueous solution 5 flows into reaction unit 1
Power is provided.
Further, it is provided with dried filter screen in Hydrogen Line 8.Because the hydrogen produced in reaction unit 1 need to be worn successively
The mixed liquor and sealing fluid 2 for crossing liquid metal 3 and the aqueous solution 5 could enter collection device 6, therefore hydrogen is entering collection dress
Vapor may be carried before putting 6.Therefore vapor is absorbed by setting dried filter screen in Hydrogen Line 8, receipts can be improved
The purity of hydrogen in acquisition means 6.
Wherein, also including detection means, detection means on collection device 6, for detecting hydrogen in collection device 6
Concentration or pressure.Because hydrogen is colourless, whether collected full hydrogen in collection device 6 therefore, it is difficult to the naked eye distinguish, and lead to
The size of the pressure or concentration and setting value of crossing comparing detection means achieves that the monitoring of amounts of hydrogen.
Wherein, also including the agitating device 11 located at the bottom of reaction unit 1, for stirring in reaction unit 1
Reactant is liquid metal 3 and the aqueous solution 5.
Finally it should be noted that：Above example is only used to illustrate the technical scheme of invention, rather than its limitations；Although ginseng
Invention has been described in detail according to previous embodiment, it will be understood by those within the art that：It still can be right
Technical scheme described in foregoing embodiments is modified, or carries out equivalent to which part technical characteristic；And this
A little modifications are replaced, and do not make the spirit and scope of essence disengaging each embodiment technical scheme of invention of appropriate technical solution.
