Utilize the reaction unit of the direct hydrogen production by water decomposition of sunshine
Technical field
The invention belongs to renewable energy source efficient production field, specifically is a kind of reaction unit that utilizes the direct hydrogen production by water decomposition of sunshine.
Background technology
On the earth, occurred since the life, just all living things depend on the sun.Photosynthesis is green plants and phycophyta change into carbonic acid gas and water glucide under the visible light effect process.The energy that the mankind depend on for existence and material are all directly with indirectly from photosynthesis.Fossil oils such as oil, coal, Sweet natural gas are exactly the photosynthetic product that nature is left us for.Because the develop rapidly in the world; The Nature is left our more and more shortage of the energy for; This scientist who has just excited various countries can only consider that to photosynthesis and mimic research thereof it is the preferred approach of solar energy chemical conversion and storage that photodissociation water is made hydrogen from the energy.Because only generate water behind the hydrogen burning, free from environmental pollution, be to be convenient to the renewable energy source that stores and transport; Moreover sun power is inexhaustible, is the desirable replacer of fossil energy.
Decomposing water with solar energy hydrogen manufacturing can be carried out through three kinds of approach:
One, photoelectrochemistrpool pool: promptly absorb sun power and luminous energy is converted into electric energy through light sun plate.Light sun plate is generally the photosemiconductor material; Receive optical excitation can produce that electronics---the hole is right; Light anode and the utmost point (negative electrode) formed photoelectrochemistrpool pool; The electronics that behind light anode extinction in the presence of the ionogen, on semiconductor tape, produces flows to the utmost point through external circuit, and the proton in the water is to extremely accepting electron production hydrogen;
Two, light helps complex catalysis: i.e. the process of manual simulation's photosynthesis water of decomposition.In green plants, extinction material is that a kind of structure is the photosensitive complex compound of magnesium porphyrin, transmits electronics and passes through quinones.Chlorophyll molecule with magnesium porphyrin structure brings out chargeseparated through absorbing the 680mm visible light, makes the water oxygenolysis and oxygen release, meanwhile, and plastoquinone generation photoreduction.From the angle of water of decomposition, in green plants photosynthesis, at first be put the oxygen energy storage through photoxidation water, be only the anabolic reaction of carbonic acid gas then.Because oxidation is put oxygen and stored luminous energy through charge transfer, in the carton dioxide assimilation process, forming the glucide midbody with proton can only be a dark reaction.Only consider that with the storage angle photosynthesis process is very good undoubtedly from the photochemical transformation of sun power.Because it has not only stored hydrogen through photochemical reaction, also stored carbon simultaneously.But for decomposing water with solar energy hydrogen manufacturing; Needed is hydrogen rather than oxygen, then needn't be on the structure and the function whole process of mimic photosynthesis effect that gets on, and only need from the get on extinction of mimic photosynthesis effect of principle; Charge transfer, basic physical and chemical process such as energy storage and redox reaction;
Three, semi-conductor catalysis: be about to TiO
2Or photosemiconductor particulate such as cds directly is suspended in and carries out the reaction of photodissociation water in the water.Conductor photocatalysis is similar to photoelectrochemistrpool pool on principle; Tiny photosemiconductor particle can be regarded as microelectrode is suspended in the water one by one; They as the sun extremely in action; Different is as photoelectrochemistrpool pool, not to be spaced between them, even level also is conceived to is on same particle.On semiconductive particles, can support platinum, have the people to treat platinum as negative electrode, but see more similarly be catalyzer from the mechanism of action of platinum.Because do not have " external circuit " have only water as electrolytical situation under; The electronics that optical excitation produced can't as in the conductor outside system in an orderly manner from " light anode " flow direction " negative electrode ", the major function of platinum is to assemble and transmit electronics to promote photoreduction water hydrogen discharge reaction.With photoelectrochemistrpool pool relatively, the reaction that the conductor photocatalysis water of decomposition is put hydrogen is simplified greatly, but through optical excitation on same semiconductive particles, produce electronics---hole is compound to very easily.Although conductor photocatalysis circulation water of decomposition is put hydrogen simultaneously and is put oxygen and fail to realize; Must in reaction system, add electron donor(ED) or acceptor as complex catalysis photodissociation water and put hydrogen respectively and put oxygen, but some new fields have been opened in the photochemical catalysis research that develops into of conductor photocatalysis.

Embodiment 3
Embodiment 3 is the variant of embodiment 2.
The difference part of present embodiment and embodiment 2 is that tubular reactor 7 ' is the tabular reactor drum.
Above-mentioned three embodiment are specially:
As depicted in figs. 1 and 2, base 4 is provided with revolute pair 10, can regulate the rotation of whole device; On revolute pair 10, connect vertical pivot 14, on the vertical pivot 14 scale is arranged, be used to regulate the height of bottom surface mirror 9; Rack beam 13 is connected with vertical pivot 14 through the first one dimension moving sets 8.On rack beam 13, pass through the second one dimension moving sets, 11 connection bottom surface mirrors 9; Vertical pivot 14 tops are through cross frame 6 fixed reactors 7; Summit 17 1 ends of reactor drum 7 are the thinnest; The thickest with summit 17 corresponding 1: 24 1 ends of reactor drum 7; When using tubular generator 7 '; Producer pneumatic outlet 5 is positioned at 1: 24 1 end of reactor drum 7, with both sides that 1: 24 1 end links to each other on, perpendicular to reactor drum 7 placement right angle mirrors 1; Fluorescent calibration plate 2 is stretched out at cross frame 6 two ends respectively; On bottom surface mirror 9, be fixed with the calibration speculum 3 that is used for adjusting position, calibration speculum 3 is identical apart from the distance on the summit 17 of reactor drum 7 with fluorescent calibration plate 2 apart from the position on the summit 18 of bottom surface mirror 9.

Reaction unit is the reaction solution container of two-sided high transparent glass, and there is corner cube mirror two sides of container, and corner cube mirror upwards extends downwards simultaneously.Below reactor drum, be cross frame, cross frame is used for fixing reactor drum, is raised to certain altitude to reactor drum simultaneously, so that from following reflected sunlight.Cross frame is connected with following vertical pivot, and vertical pivot can rotate on base, so that reaction unit receives sunshine, through calculating, when the diagonal lines of the container of containing reaction solution was vertical with solar ray, reactor drum received sunshine and reaches maximum.A rack beam is arranged on the vertical pivot, and rack beam is connected through a moving sets with vertical pivot, promptly moves up and down only, can not rotate.On rack beam, there is individual bottom reflection mirror to be connected with rack beam equally through the one dimension moving sets.Scale is all arranged on vertical pivot and rack beam, and the maximum optical that can write down every day in each moment through scale is shone the position, after the record, need not use all at every turn and proofread.At the cross frame two ends, two silver-colored optical alignment plates are arranged, and the bottom reflection mirror there are two speculums accordingly.The distance of speculum mirror forward end apex apart from the bottom surface communicates with the distance of container front end with fluorescence check and correction plate, and therefore when the light of mirror reflects just in time impinged upon on the check and correction plate, the light of bottom reflection mirror can fully be radiated at the bottom surface of reactor drum.The bottom reflection mirror is bigger slightly than reactor drum, so some light is through finding the bottom surface of reactor drum after the mirror reflects that extends below.The eliminating of hydrogen for ease, reactor drum bottom surface glass level, the top upper glass tilts, and reaching the thickest near two speculum crevice place container thickness, establishes venting port herein.Because the hydrogen that reaction generates can feed fuel cell, therefore establish TP at gas outlet, pilot-gas (hydrogen+oxygen+moist steam) temperature is about 75 ℃, to improve the efficient of fuel cell.
About enlarging the theoretical proof of irradiated area:
Shown in left figure (vertical view),,, can expand as original three times (S2=2*S1) to the illuminating area of single face through the reflection of speculum when the level amount of light during perpendicular to the diagonal lines DE of reactor drum.Computation process is: suppose that Ray Of Light is through reflection; The edge point A place of the final reactor drum that is provided with; The distance of two sections reflections is respectively a and b, must have so, under the situation that does not add speculum; This bundle light will shine the B point a+b place that stretches out, so the edge of S2 area is through the light that reflexes to container edge at the track that does not have under the speculum situation.Therefore can release,, then must drop on the reactor drum through reflection if Ray Of Light can drop in the S2 scope.Through corner cube mirror and bottom reflection mirror on every side, maximumly in theory can promote six times to illuminating area for reactor areas.Certainly this also with the length of mirror, the adjusting of bottom reflection mirror position, whether the light level amount vertical relevant with diagonal lines DE.
Catalyst system therefor of the present invention can carry out under normal pressure, need not make vacuum.In addition, because reactor drum is a double-sided glass device that the big thickness of area is little, catalyst levels is little again; Even catalyst precipitation also is to form very thin which floor at reactor bottom, the upper strata catalyzer can touch illumination; Produce hydrogen, lower floor's catalyzer also can touch illumination through reflected light in this device, produces hydrogen; Drop to deposition to the influence of hydrogen minimum, the equipment that therefore need not stir too.This reactor drum can be made tubulose equally, and should prevent deposition this moment, adds the pulse gas disturbance equipment.The gas disturbance equipment that this invention is used, energy does not need consumed power equally from sun power, has realized zero energy consumption.Simultaneously, the strict sealing of this reaction unit is the plastics reactor frame around the device, and levels is a glass, and reactor frame and glass seal with seal strip.The also available reflectance coating of speculum replaces to reduce cost.At gas outlet TP control hydrogen temperature is set, 75 ℃ saturated wet hydrogen feeds the fuel cell best results.Present device is simple, practicality and strong innovation, a lot of deficiencies of invention of the same type before having improved simultaneously; As increasing sunshine direct projection area, the amount of augmenting response liquid receives illuminating area through the reflection increase; Upper and lower surfaces receives illumination simultaneously, rotates convenience etc. according to sun irradiation angle.
