The invention relates to solar power, in particular a highly concentrating solar energy installations. The solar combined concentrating power plant comprising a primary and a secondary mirror concentrator, tracking sensor, a receiver located in the top of the primary hub perpendicularly to its optical axis with the cooling device according to the invention in the central portion of the primary tapered hub having a through hole coaxially to its optical axis positioned tracking sensor, located within the secondary poluparaboloidnogo hub deployed at 360 ° around the optical axis of the conical hub, while on the outer side of the secondary poluparaboloidnogo concentrator placed thermocouples, and solar cells placed on the surface of the hollow tubular coolant in the form of a circle with an inlet and an outlet, wherein the primary conical hub base tracking sensor, secondary poluparaboloidnogo hub and a hollow tubular heat transfer medium in the form of a circle fixed on the insulator connecting flat circular disc. The invention must provide expansion species conversion of solar radiation energy in the form of electric current, and in the form of thermal energy for heating water.
DESCRIPTION OF THE INVENTION
The invention relates to solar power, in particular a highly concentrating solar energy installations.
The cost of energy produced can be reduced in proportion to the multiplicity of concentrating solar radiation.
In the practical implementation of the different methods of conversion of highly concentrated solar radiation is a problem of development and creation of combined solar power generating simultaneously different kinds of energy, such as heat and electricity.
The need for this is particularly relevant for use in solar energy scarce and very expensive semiconductor materials.
Known concentrating solar power plant (Alferov. Photoelectric conversion of concentrated solar radiation. Leningrad. Science. 1989 p.301).
The disadvantage of the known limitations of the power plant is of the form converting concentrated solar radiation into electrical energy only.
The closest to the technical nature of the present invention is a project concentrating solar power plant Cassegrain (DSC), developed by TRW's (USA) according to the construction scheme and design scheme DSC DSC (ed. Alferov. Photoelectric conversion of concentrated solar radiation. Leningrad. Science. 1989. p.299, s.281, s.233).
Known two-mirror system concentrating Kassergena (DSC) comprises a primary and a secondary mirror concentrator, tracking sensor, a receiver located in the top of the primary hub perpendicularly to its optical axis with the cooling device.
A major shortcoming of the known solar concentrating power plant with DSC is the limited type of solar conversion into electric energy only.
The object of the invention is to empower species concentrating solar radiation conversion power plant in the form of electrical current energy, and in the form of thermal energy for heating water.
The use of the present invention is able to construct a highly efficient concentrating solar power plant of the combined, simultaneously reconstitutive solar energy into heat energy for heating the water and electrical energy consumer.
The above technical result is achieved by the fact that the proposed solar combined concentrating power plant comprising a primary and a secondary mirror concentrator, tracking sensor, a receiver located in the top of the primary hub perpendicularly to its optical axis with a cooling device, in the central portion of the primary tapered hub having a through hole coaxially with it the optical axis is placed tracking sensor disposed within the secondary poluparaboloidnogo hub deployed at 360 ° around the optical axis of the conical hub, while on the outer side of the secondary poluparaboloidnogo concentrator placed thermocouples, and solar cells placed on the surface of the hollow tubular coolant in the form of a circle with inlet and outlet openings, and the base of the primary conical hub, tracking sensor, secondary poluparaboloidnogo hub and a hollow tubular heat transfer medium in the form of a circle fixed on the insulator connecting flat circular disc.
When rotating around the semi-parabolic tapered line concentrator optical axis 360 ° to obtain the aforementioned surface in the form of secondary concentrator poluparaboloidnogo deployed 360 ° around the optical axis of the conical hub.
BRIEF DESCRIPTION Figures 1 and 2.
Figure 1 shows the general scheme of the proposed combination of solar concentrator power plants (front view)
Figure 2 is a diagram of a combined solar concentrating power plant (top view)
Solar combined concentrating power plant comprises a primary conical hub 1, insulating connecting flat circular washer 2, the central through-hole 3 of the primary conical concentrator 1, a tracking sensor 4, photocells 5 tracking sensor 4, the tracking sensor 4 partitions 6, hollow tubular heat transfer medium in the form of a circle 7, photocells 8 on the outer surface of the hollow tubular coolant in the shape of circle 7, the secondary poluparaboloidny deployed 360 ° concentrator 9, thermocouples 10 on the outer side of the secondary poluparaboloidnogo deployed 360 ° concentrator 9, an inlet 11 of a circular tubular hollow coolant 7, an outlet 12 7 circular tubular coolant.
Solar concentrating the combined power plant operates as follows.
Primary conical hub 1 collects the sun's rays through precise moving the tracking sensor 4 on the mirror surface of the secondary poluparaboloidnogo deployed a 360 ° hub 9, which reflected the sun's rays are concentrated in the space on the outer surface of a hollow tubular coolant in the form of a circle with photocells 7 8. The water flowing through the hollow tubular heat transfer medium in the form of a circle 7, time to get hot, selecting additional heat and cooling solar cells 8. on the outside of the heated concentrated luminous flux secondary poluparaboloidnogo deployed a 360 ° hub mounted thermocouples for more electricity.
