Description
Technical field
The present invention relates to the efficient technique of rainwater utilization field of Hydrogen Energy, especially a kind of Hydrogen Energy based on sun power and gasifying biomass produces the defeated integral system of storage.
Background technology
The energy is one of mankind's critical elements of depending on for existence and development, is also the important substance basis of national economy and social development.But existing energy supply system depends on the fossil oil such as coal and oil, excessively use fossil oil to create severe contamination to environment, and exacerbate global warming.On the Chinese side, the energy structure of taking as the leading factor with coal seriously restricts the high speed development of current economic and society, simultaneously too high dependence on foreign countries for oil serious threat to national energy security.Meanwhile, the contradiction between the non-renewable and growing energy demand of fossil oil also just sharply highlights, and the reproducible substitute energy seeking to clean has become a current difficult problem urgently to be resolved hurrily.
In recent years, the researchist of various countries has turned one's attention to Hydrogen Energy, and hydrogen is the most general element of occurring in nature, and it accounts for 75% of universe total mass according to estimates.The efficiency of combustion of hydrogen and calorific value are all very high, and under equal in quality, the calorific value of pure hydrogen is almost equivalent to 2.8 times of current automobile power fuel (gasoline, diesel oil etc.) combustion heat value.The products of combustion of hydrogen is only water simultaneously, can not to environment.
Mainly utilize the mode hydrogen producings in next life such as water decomposition hydrogen manufacturing, hydrogen making by natural gas reformation, hydrogen production from coal gasification at present, although hydrogen belongs to clean energy as end product, the production process of hydrogen needs the electric energy consuming a large amount of fossil oils or high-quality.In gas renormalizing reaction, existing technology is that direct gas-firing is to provide the heat required for reaction, but the highest theoretical combustion temperature of Sweet natural gas can reach 2300 DEG C, and the temperature of reaction of hydrogen making by natural gas reformation is only 800 ~ 1000 DEG C, not mating between temperature, will cause serious energy grade loss, and hydrogen production from coal gasification technology exists problems equally.Existing fossil oil hydrogen producing technology all adopts the mode of direct combustion material to provide reaction heat, although can simple flow structure, the environmental pollution caused and energy grade loss also be can not ignore.
On the other hand, according to the preciousness of distribution of resource characteristic and urban land resource, make the production facility of hydrogen often build away from remote districts such as customer centers, long-distance sand transport hydrogen becomes inevitable thus, and existing transfer ways mainly comprises gaseous hydrogen conveying and liquid hydrogen is carried.Hydrogen is normally carried by instruments such as long-tube trailers by gaseous state mode of movement after being forced into certain pressure, the tube bank that the steel cylinder that general is about 0.5m by 9 diameters, is about 10m, design effort pressure is 20MPa forms, but the hydrogen weight in high-pressure aerated steel cylinder only accounts for about 1.6%, namely transport process has done a large amount of idle work, also need to consume a large amount of hydrogen compression work, and also there is many potential safety hazards in storage hydrogen pressure container.And liquid supplying way is to 21K post liquefaction by hydrogen deep cooling, recycling groove tank car or pipeline transport, although its volume energy density is respectively 845 times and 6.5 times that hydrogen and 15MPa under normal pressure transport hydrogen under pressure, but consume in liquefaction of hydrogen process that a large amount of cooling energies accounts for its storage power 30%, and liquid hydrogen easily leaks and can not preserve for a long time, also need to adopt all kinds of technique means to keep the thermal insulation of liquefied pot to reduce vaporization losses.
Relative fossil oil, the solar energy resources of China is very abundant, annual day solar radiation quantity be 180W/m
2, and showing the low sun power areal distribution feature of Xi Gaodong, the sunshine durations in west area year such as Xinjiang such as Tibet, Qinghai of China, especially more than 3000 hours, belong to one of abundant area of world's solar energy resources.Meanwhile, the biomass straw annual production of China is 8.42 hundred million tons, and Collection utilization amount can reach 6.86 hundred million tons, Utilization prospects is boundless.Therefore, can make full use of these clean renewable energy sources to produce hydrogen, this not only by contributing to the consumption reducing fossil oil, also can realize low-quality renewable energy source to the conversion of energy of high-quality hydrogen simultaneously.
Although existing hydrogen transport system directly pure hydrogen is sent to the users such as hydrogen station, the efficiency transported is very low, and transport with storage process in also there is many safety issues.Should find and a kind ofly easily synthesized by hydrogen and easily resolve into the intermediate carrier of hydrogen, to improve the stability in storage of hydrogen, safe transport can not only be realized by the existing system that transports, also can reduce the technical requirements to user side.
The energy development direction had an eye on the future, not only requires to possess clean and Hydrogen Energy transformation technology efficiently, simultaneously Hydrogen Energy production, store and transport side and also should pursue pollution-free, low cost.While by production of renewable energy resources hydrogen such as abundant sun power and biomass, the propagation and employment storing up defeated integral system and contribute to Hydrogen Energy is produced, for the contradiction effectively alleviated between growing energy demand and limited fossil energy reserves provides approach by building scientific and reasonable Hydrogen Energy.
