Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
The embodiment of invention, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, belongs to protection scope of the present invention.
The embodiment of the present invention is described in further detail below in conjunction with attached drawing, is implemented as shown in Figure 1 for the present invention
The method flow schematic diagram using sun photoinduction water power from hydrogen manufacturing that example provides, which comprises
Step 1 places electrode at the water vapor bubbles both ends of region of discharge first and adds voltage, forms inhomogeneous field, water
Individual gas atoms in bubble generate fast electronics (high energy electron) under electric field action；
Step 2 makes the heavy particle in the water vapor bubbles obtain certain energy under the action of electric field, makes at water vapor bubbles
In the critical state of electric discharge；
Here, the heavy particle in water vapor bubbles includes molecule, neutral particle.
Then step 3 punctures the water vapor bubbles under the induction of sunlight and discharges, formed discharge channel generate etc. from
Daughter realizes that continual and steady electric discharge generates plasma hydrogen preparing.
Specifically, under the continuous action of sunlight, it on the one hand can prevent or delay the compound and suction of electronics and ion
Attached, the time-to-live of extending channel, is on the other hand the consumption and electron diffusion losses for supplementing electronics in channel, and realization is held
Continue stable electric discharge and generates plasma hydrogen preparing, specifically:
On the one hand, the contradiction that sunlight is directly punctured that liquid water ionization is difficult to realize by the present embodiment is transferred to sun photo-induction
In water guide breakdown.When sunlight and aqueous medium, which directly act on, generates plasma, initiating electron is usually by multiphoton ionization
It provides, or is provided by the thermal excitation of impurity.Since pure aqueous medium is only possible to provide initiating electron by multiphoton ionization,
Energy needed for thus sunlight acts on generation plasma with pure aqueous medium is very high.It, can be abundant under electric field preionization
There is provided energy using the sunlight of wide spectrum makes water attack wear ionization, is conducive to make the particle of high level excitation state in water further to inhale
Solar energy is received, with the collision between accelerated particle, punctures water and forms plasma channel.
On the other hand, the present embodiment additionally provides a kind of effective ways of electric field preionization water, theoretical according to bubble breakdown,
It, can when using gas as region of discharge since gas breakdown electric field ratio liquid is much lower when there is bubble in a liquid
Electric field strength needed for preionization is effectively reduced, to make full use of solar energy induction water vapor bubbles breakdown.And the gas in water
Bubble mechanism greatly reduces applied voltage duration very long situation.And the method that bubble is generated in liquid, substantially have three
Kind: (1) liquid itself gassiness, including the method by additional bubble；(2) electrode emission electric current heats liquid nearby and is allowed to gas
Change；(3) the high energy electron impinging fluid molecule in liquid is allowed to ionization and generates gas.When there is bubble in a liquid, due to gas
The breakdown field strength of body is more much lower than liquid, and electric field strength is again higher than liquid in bubble, so electricity will occur first for bubble
From the high energy electron for ionizing generation ionizes fluid molecule, and generating more gases expands bubble.On this basis, gas
The presence of bubble makes the electric field in electric field and bubble in water change, and can change interelectrode field distribution, bubble it
Between mutually merge, can greatly reduce breakdown delay time.
Secondly, the bubble channel in liquid water will generate a large amount of initiating electron, and have a large amount of grain under electric field action
Son is from ground state transition to upper state, and the particle in water vapor bubbles is easy the amount of absorbing solar energy to obtain more high level excitation state at this time
Energy, when this energy is sufficiently large, collision between accelerated particle can be such that atom excitation is ionized.The light of highly excited level atom
Ionization and the direct collision of electronics and atom, can further ejected electron.Solar energy can prevent or delay electronics
With the compound of ion and absorption, under the lasting focusing illumination of sunlight, so that the electronics being adsorbed on neutral molecule is by again
Releasing becomes free electron, with the electron density for maintaining channel to reach certain, so that the time-to-live of extending channel, realizes
Continuous discharge generates plasma.
In addition, the water vapor bubbles of above-mentioned region of discharge are persistently generated by air pump；Or it is gentle by local fast heating in water
Change and is formed.
Based on above-mentioned method, the embodiment of the invention also provides a kind of dresses using sun photoinduction water power from hydrogen manufacturing
It sets, is illustrated in figure 2 the apparatus structure schematic diagram provided in an embodiment of the present invention using sun photoinduction water power from hydrogen manufacturing, it is described
Device mainly includes cathode electrode 1, plasma discharge region 2 (also as solar radiation area and Bubble Region), air pump 3, anode
Electrode 5 and condenser lens 6, in which:
The plasma discharge region 2 is set between the cathode electrode 1 and anode electrode 5, and lower part is connected with gas
Pump 3；
The condenser lens 6 is located at the top of the plasma discharge region 2；
Water vapor bubbles 4 are constantly constantly generated in the plasma discharge region 2 by the air pump 3, become region of discharge
For gaseous state, condition is provided for realization continuous discharge；
Then it records voltage on the cathode electrode 1 and anode electrode 5, forms inhomogeneous field, in the water vapor bubbles 4
Individual gas atoms free electron and ion will be formed under electric field action；Make the water vapor bubbles 4 under the action of electric field
Interior heavy particle obtains certain energy, and preionization occurs；Sunlight 7 is introduced by the condenser lens 6 again, makes the aqueous vapor
4 disruptive discharges under the induction of sunlight are steeped, discharge channel is formed and generates plasma, realize that continual and steady electric discharge generates
Gas ions hydrogen manufacturing.
In the specific implementation, after lighting electric discharge under sun photoinduction on the one hand sunlight is used to supplement plasma channel
On the other hand the consumption and electron diffusion losses of middle electronics are used to prevent or delay the compound and desorption of electronics and ion attached,
Under the lasting focusing illumination of sunlight, so that the electronics being adsorbed on neutral molecule is released again as free electron,
With the electron density for maintaining channel to reach certain, so that the time-to-live of extending channel, realizes that continuous discharge generates plasma
