Description
Technical field
New energy technology of the present invention neck and power-generating heat-absorption technical field of material, be specifically related to a kind of novel solar
Absorber matrix material is used in generating.
Background technology
The energy of shortage has had a strong impact on life and the development of restriction society of people.Abundant solar energy is important clear
The clean energy, is the energy that can freely utilize of inexhaustible, nexhaustible, pollution-free, cheap, the mankind.The first oil crisis
Afterwards, various countries competitively carry out cleaning and the applied researcies of regenerative resource, especially solar energy such as solar energy, water energy, wind energy
Applied research is the most extensive.
Solar energy does not has any nonstaining property as a kind of green energy resource to environment, and its source is simple, it may be said that
It is that it is inexhaustible in the existence time limit of the mankind.Solar energy is not only the disposable energy, or cleaning energy
Source, its aboundresources, generally exist, without transporting, also can freely use, the most important thing is environment is not had any pollution.Too
Sun also can have the advantage not available for other generation modes many because of the particularity of solar energy by battery: without geographical restrictions, no
Consume fuel, scale is changeable, motility is big, pollution-free, noiselessness, safe and reliable, the construction period is short, safeguard simply,
There is the probability of large-scale application.So a lot of experts go solar energy to exploitation as the alternative energy, it is desirable to too
Sun can be brought benefit to the mankind.Nowadays the solar energy used have greatly by solar cell conversion get.Because
Solaode has sensing to light, it is possible to the luminous energy being radiated at its surface is converted to electric energy.At present, in the effort of relevant expert
Under, solaode is own through having moved towards commercialization and industrialization.
Solar electrical energy generation kind is a lot, and at present, more ripe has solar energy power generating and solar energy thermal-power-generating.Crowd
In many solar utilization techniques, solar energy thermal-power-generating technology is described as most having prospect, utilizes solar energy the most on a large scale
Technology.Solar energy thermal-power-generating is to utilize condenser to assemble solar energy, after absorber absorbs, changes into heat energy, produces high temperature
Steam or gas enter turbine LP rotors or Gas Turbine Generating Units produces electric energy.Different by optically focused form, solar energy
Heat generating can be divided into tower type solar energy thermal power generation, trough type solar power generation and the generating of disc type solar energy heat.Tower-type solar thermal
It is each that the feature that electricity generation system is high due to focusing ratio, thermodynamic cycle temperature is high, thermal losses is little, system is simple and efficiency is high obtains the world
The attention of state, is that current each state is all at the advanced hot generation technology of large solar studied energetically.And as the tower sun
The air heat-absorbing device of the core that can hot generate electricity, high temperature endothermic body material therein is responsible for and receives sun optically focused energy, and heat absorption,
The important function of heat exchange, affects the stability of whole heat generating system and the height of efficiency.
Tower-type solar thermal power generating system includes: optically focused subsystem, collection thermal sub-system, power generation sub-system, heat accumulation subsystem
With supplementary energy subsystem, have that scale is big, heat transfer distance is short, thermal losses is few, focusing ratio and a temperature relatively high, the suitableeest
Generate electricity together in large-scale grid connection.Tower type solar heat extractor is broadly divided into indirect irradiation heat extractor and direct irradiation heat extractor two is big
Class, the requirement to heat extractor is mainly: can bear solar energy metric density and the gradient of certain numerical value, it is to avoid hot-spot is sent out
Raw, the flow distribution of fluid matches with energy density distribution, and efficiency is high, the most easily makes, cost economy.Inhale at tower type solar
In hot device, absorber material is the core component of heat extractor.Due to Salar light-gathering energy-flux density inhomogeneities and unstability
The absorber local hot spot formed causes that material thermal stress damage, air flow stability be poor, in the case of system complex, Large Copacity
System reliability and durability are the most high, therefore, and feature based on solar energy thermal-power-generating heat-absorption device and absorber material is wanted
Ask, need to design the heat-absorbing material of a kind of heat extractor for tower-type solar thermal power generating system.
