Description
Technical field
The invention belongs to solar energy utilization technique fields, more particularly to one kind being used for dish-style or tower type solar speculum
The technology of the Accumulated Heat Units of heat build-up.
Background technology
One side mankind's energy-consuming level is continuously improved, on the other hand conventional fossil energy increasingly depleted, and conventional
The adjoint pollutant emission problem of fossil energy cannot increasingly meet the needs of people are for future source of energy.Solar energy is as a kind of
Inexhaustible new cleaning fuel just increasingly obtains the attention of people, for solar energy development just
Increasingly making progress.
Solar power generation popular at present is broadly divided into two kinds of forms of photovoltaic generation and solar energy thermal-power-generating.Wherein light
Volt power generation receives sunlight using solar panel or battery thin film, and luminous energy is directly converted to electric energy, but is generating electricity
There is very big deficiency in terms of efficiency and battery life.Solar energy thermal-power-generating can be divided into trough type solar power generation, tower type solar
Thermal-arrest generates electricity and butterfly solar power generation.For trough type solar power generation since focusing ratio is not high, the vapor (steam) temperature of generation is relatively low, because
This generating efficiency is restricted.Butterfly solar power generation is then made of the small-sized concentrating generation device of multiple dispersions, single-machine capacity
It is small, equally it is unfavorable for the raising of whole generating efficiency.And the power generation of tower type solar thermal-arrest is then to use numerous reflectors, it will be big
The sunray of area is gathered on a heat dump, therefore can obtain very high temperature, and electricity generation system steam initial temperature is made to carry
Height obtains higher generating efficiency still, still, for tower-type electricity generation system, limits thermal-arrest generating efficiency at present and improves
A key factor be collecting efficiency problem.In order to obtain more high-power and higher temperature field, this is just needed using more
Condenser more sunlights are gathered on the heat dump of thermal-arrest tower top, at the same time, in order to receive more multimirror
Reflection light, it is necessary to the very high of thermal tower construction will be collected, this is all extremely disadvantageous for engineering construction and equipment operation.And
And due to the influence of cosine effect, tower thermal-arrest cannot the fully effective solar energy using in heat collecting field.
The Accumulated Heat Units of novel efficient and efficient collecting system are developed, for reducing photo-thermal power generation cost and raising
Power plant's reliability is of great significance.
Solar light-heat power-generation is realized into extensive industrialization, most critical is still in the breakthrough of technical aspect, in heat build-up
There are technological innovation, technological break-through in mode, the technology of the once property changed be needed, to push energy technology true to remove from office
Life.
