Description

Integrated form Hydrogen Energy produces storage and recycling device
Technical field
The utility model relates to renewable energy utilization technology, refers to that a kind of integrated form Hydrogen Energy being applicable to hydrogen fuel cell system produces storage and recycling device particularly.
Background technology
Grow continuously and fast along with socioeconomic; increasing to the demand of the energy; the conventional mineral fossil fuel as main energy sources is caused to consume minimizing rapidly; all there is long-term and huge energy demand and supply pressure in China and even the world; consequent worldwide energy crisis is constantly sounded the alarm to the mankind, and increasing scientific research personnel has to make great efforts to excavate the new forms of energy of reproducible utilization.
In addition, conventional mineral fossil fuel brings the dominant of environment for human survival and recessive threat also should not be underestimated, wherein atmospheric warming effect is the topmost problem of environmental pollution that the mankind face, and is also that countries in the world scientific research personnel needs the difficult problem that jointly overcomes in recent ten years always.On the one hand, the carbon dioxide produced as industries such as coal fired power plant, metallurgy, iron and steel, cement in large scale industry is main greenhouse gas, and the effective way solving atmospheric warming effect reduces the discharge of these industrial carbon dioxide.On the other hand, along with the fast development in city, automobile quantity is in continuous increase, particularly in the country of the fast developments such as China, the vehicle exhaust discharge quantity that gasoline, diesel combustion produce also exponentially ascendant trend, its emission mainly contains carbon monoxide, hydrocarbon compound, oxygen sulfur compound and oxynitrides, and these compounds are very harmful to environment and the mankind's.
In order to solve an above-mentioned difficult problem, scientific research personnel contemplates and adopts hydrogen energy source as fuel-cell device.Hydrogen fuel cell device is owing to having following significant advantage, be subject to the extensive attention of many developed countries: first, the fuel of this cell apparatus is hydrogen and oxygen, its product is clean water, do not produce carbon monoxide and carbon dioxide during itself work, do not have sulphur and other particulates emissions to discharge yet; The second, compared with the automobile using gasoline or diesel oil with tradition, adopt the automobile energy transformation efficiency of hydrogen fuel cell device up to 60 ~ 80%, be 2 ~ 3 times of regular gasoline or diesel engine; 3rd, this cell apparatus pollutes few, and noise is little, and battery assembling is changeable, flexible and convenient to use.But its inferior position is also apparent, Cost Problems remains the key point of restriction hydrogen fuel cell device development, except Hydrogen Energy produce electric quantity consumption itself very high except, more restricted is that Hydrogen Energy storage and release conditions are comparatively harsh, also there is more potential safety hazard in Hydrogen Energy simultaneously in trans-utilization process, and the above defect is that hydrogen fuel cell device realizes business-like yoke all the time.
At present, the mode of hydrogen energy storage is roughly divided into physics storage hydrogen and chemistry storage hydrogen two class.Physics storage hydrogen mainly contains high pressure tank storage hydrogen, liquefaction hydrogen storage, hydrogen physisorption etc.The advantage of high pressure tank storage hydrogen be cost low, can be high pressure resistant, shortcoming there is inflammable and explosive potential hazard.Liquefaction hydrogen storage adopts cryogenic vacuum basin, and its storage capacity reaches pressure pan hydrogen storage content more than 5 times, and energy density is high, but due to the cost of liquefaction of hydrogen very high, service condition is very harsh, therefore is only applied to aerospace field.Hydrogen physisorption mainly utilizes the superhigh specific surface area materials adsorption hydrogen molecules such as activated carbon, fluorite, sepiolite, although it has safe and reliable, that reservoir vessel deadweight is low, storage hydrogen efficiency is high feature, but mostly also under test, difficulty has substantial breakthrough in a short time.
Chemistry storage hydrogen mainly contains hydride hydrogen-storing, complex hydrides storage hydrogen, metal or compound and water and reacts and store up hydrogen and organic substance Chu Qing etc.Hydride hydrogen-storing refers to that some transition metal, alloy, intermetallic compound are due to reasons such as its special lattice structures, hydrogen atom is than in the tetrahedron being easier to enter metal lattice or octahedral interstice under certain condition, form metal hydride, its storage volumetric hydrogen density is large, can reach 100kg/m 3, but its quality comparation is large, and condition when putting hydrogen is harsh, and thus its cost is higher, and utilance is lower, which also limits its utilization in hydrogen fuel cell system.Complex hydrides storage hydrogen refers to the compound that two or three light metals are formed with hydrogen as Mg, Al, B or Li etc., its hydrogen storage content is very high, and have price advantage, but be still in R&D process present stage, the cycle-index improving its absorption and release hydrogen is further the core of research at present.Metal or compound and water react and store up hydrogen, such as comparatively active metal and water react can releasing hydrogen gas, constantly supplying hydrogen when needs hydrogen by chemical reaction like this, stopping reaction when not needing hydrogen, but its reaction rate controls very not easily.And the limitation that torpescence metal and water react is comparatively large, releasing hydrogen gas amount is less than normal, and reaction efficiency is too low, is not enough to practical application.Organic hydrogen storage realizes by the reversible reaction of unsaturated liquid catalytic organism hydrogenation dehydrogenation.Although the method hydrogen storage content is higher, be also convenient to transport, the condition that hydrogen is inhaled in its dehydrogenation is comparatively harsh, and catalyst very easily poisoning and deactivation.
Therefore, those skilled in the art attempt for hydrogen fuel cell system finds a kind of storage to Hydrogen Energy and the few and auxiliary equipment of hydrogen utilization quickness and high efficiency safety of release restrictive condition always, but not yet obtain desirable result up to now.
