Description
Technical field
What the present invention relates to a kind of energy efficiently utilizes system, particularly a kind of energy-storage type solar energy system.
Background technology
In the century in the past, the prelude of big industrial age has been opened in the development and utilization of fossil energies such as coal, oil, natural gas, and the human total year energy supply amount in century-old front and back has increased nearly 10 times.Yet, the using energy source of immoderate development of resources and poor efficiency has caused a large amount of wastings of resources, serious day by day ecological environmental pollution and the shortage of energy resources, the human existence space has been subjected to very big threat, in new century, energy science is had to simultaneously in the face of the triple burden of the wasting of resources, shortage of resources and environmental pollution, therefore, people turn to sight in the storage of the efficient utilization of renewable resource and energy gradually.
What the world energy sources reserves were maximum is solar energy, account for about 99% of the renewable energy resources, because of it is inexhaustible, nexhaustible, pollution-free, cost is low feature is subjected to extensive concern, the numerous and confused research work that launches the solar energy utilization in countries in the world, but existing solar energy utilization system mainly is to adopt photovoltaic generating system to provide electric energy to other devices, as solar cell.And the disadvantage of solar energy system is exactly to be subjected to the influence of weather bigger, owing to unsteadiness electrical network is had bigger impact when being incorporated into the power networks.
Summary of the invention
The object of the present invention is to provide a kind of have " peak load shifting " effect, good stability, a kind of energy-storage type device of solar generating that energy utilization ratio is high.
The object of the present invention is achieved like this:
Comprise photovoltaic generating module, power storage module and electric control system, described power storage module comprises solar collector, regenerative apparatus and electrical storage device electrical storage device, the part solar energy that solar collector is collected is stored in the regenerative apparatus, regenerative apparatus provides heat for electrical storage device, photovoltaic generating module links to each other with electrical storage device with electric control system, and electrical storage device is connected with electric control system.
Described electrical storage device is the Na-S battery.
In order to overcome the problem that prior art exists, the invention provides a kind of novel energy-storage type solar energy system.As the huge new and renewable sources of energy development technique of a kind of potentiality to be exploited, adopt accumulation of heat, electric power storage skill to realize the efficient utilization of energy.
The present invention compares its advance with existing solar energy system and is, on the solar energy power generating basis, increased the solar energy power accumulating module, when the energy consumption ebb with under the photovoltaic generation part electrical power storage, when the energy consumption peak, again electric energy is discharged, thereby make this system have the effect of " peak load shifting ", strengthened the stability of system.
Select the electric power storage of Na-S battery in the power storage module of the present invention for use, with respect to other storage battery, Na-S battery specific energy height, electric current, high power discharge greatly, can reach 10～15 years useful life.But the Na-S battery also has weak point, its working temperature is at 300-350 ℃, so, need certain heat tracing when battery operated, so be equipped with regenerative apparatus again in this power storage module, the part solar energy of collecting is stored the working temperature that also can normally keep the Na-S battery when solar irradiation is not enough.
The present invention is owing to adopt the modularized design mode, and other modules that can be coupled are as wind power generation module, biological energy source module etc.
The present invention utilizes solar energy to advance power supply, has reduced the dependence to fossil energy, thereby has saved non-renewable energy resources.
Description of drawings
Fig. 1 is a simple and easy flow chart of the present invention.
Fig. 2 is a fundamental diagram of the present invention.
Embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1, the composition of energy-storage type device of solar generating of the present invention comprises photovoltaic generating module, power storage module and electric control system, described power storage module comprises solar collector, regenerative apparatus and electrical storage device electrical storage device, the part solar energy that solar collector is collected is stored in the regenerative apparatus, regenerative apparatus provides heat for electrical storage device, photovoltaic generating module links to each other with electrical storage device with electric control system, and electrical storage device is connected with electric control system.Described electrical storage device is the Na-S battery.
During sunshine, on the one hand solar energy sends electric energy by photovoltaic generating module, be sent to electric-control system after, infeed electrical network, unnecessary electric energy is deposited in the electrical storage device (Na-S battery).On the other hand, the part solar energy that is absorbed by solar collector passes through regenerative apparatus, and this part thermal energy storage is got off, and guarantees for Na-S battery operate as normal provides heat.
In conjunction with Fig. 2, the course of work of the present invention is:
During sunshine, open valve a, d earlier, valve-off b, c, a part of solar energy are absorbed by solar collector heat are passed to heat-transfer working medium in the heat collector, and working medium is carried the heat energy regenerative apparatus 1 of flowing through, with this part thermal energy storage in regenerative apparatus 1.The working medium that flows through regenerative apparatus flows back to the solar collector module under the driving of pump 1 finishes the accumulation of heat circulation.Valve-off a, b, c afterwards, open valve d, after treating enough working medium (cold working medium) regenerative apparatus that refluxes back under the driving of pump 2, valve-off a, d, beat valve and open b, c, the regenerative apparatus heat release with heat transferred heated at constant temperature chamber 2, is filled heat-storing material by heat-transfer working medium in the heating chamber, the periphery is equipped with insulation material, and heated at constant temperature chamber 2 guarantees for electrical storage device (Na-S battery) provides heat.
Solar energy sends electric energy by photovoltaic generating module on the other hand, be sent to electric-control system after, infeed electrical network, unnecessary electric energy is deposited in the power storage module (Na-S battery).
