Definitions
- the invention relates to solar technology and can be used in solar power plants such as “follower plate”, “tray” and “solar tower” and other similar systems.
- the closest to the claimed device according to the set of essential features is a solar energy concentrator, disclosed in the copyright certificate SU 1347068, published on 10.23.1987, including the primary and secondary concentrators and an energy converter.
- the disadvantages of this technical solution are the technological and operational complexity, as well as insufficiently high efficiency.
- the problem to which this invention is directed is to simplify and cheapen the design, as well as to increase its effectiveness.
- the technical result achieved by using the present invention is to increase the availability of technology, simplify settings and remove strict restrictions on the size of the mirror system.
- the device for energy concentration containing the main concentrator and the energy converter includes an additional concentrator installed in the focal zone of the main concentrator, and the energy converter is installed in the focal zone of the additional concentrator, while the additional concentrator is made in the form of a segment concave cylindrical or spherical surface.
- the main the concentrator can be made in the form of a set of flat mirrors oriented so that the axis of the reflected beam passes through the center of the sphere or the axis of the cylinder of the additional concentrator, and the energy converter in the form of a heat exchanger or in the form of a distributed system of active or passive elements.
- Flat mirrors can be installed at an angle to the horizon equal to half the geographical latitude of the location of the device.
- the surface of the main concentrator on which the flat mirrors are mounted can be made spherical or cylindrical with a radius equal to two distances from its surface to the center of the sphere or cylinder axis of the additional concentrator.
- the heat exchanger can consist of at least two parts and can be made in the form of a spherical ring or annular spherical platform.
- a mirror in the form of a truncated segment of a sphere or a truncated cylinder is used as an energy concentrator located on the mast.
- Flat mirrors are oriented so that the axis of the reflected beam passes through the center of the sphere of the concentrator or through the axis of the cylinder of the additional concentrator.
- the formation of the focal zone of an additional spherical or cylindrical hub does not depend on the accuracy of the location of the planar mirrors of the system by distance and horizontal location. Precise adjustment of flat mirrors only in angles is required.
- figure 1 presents a General view of the device power plant type "follower plate"
- FIG. 2 is a general view of a servo-plate type device with an annular arrangement of flat mirrors and with a heat exchanger in the form of a spherical ring;
- FIG. 3 is a schematic illustration of a device, side view
- FIG. 4 is a view A of FIG. 3;
- FIG. 5 is a General view of the device type "tray"
- FIG. 6 is a general view of a device of the "tray" type with mirrors rotated by an angle equal to half the geographical latitude of the location of the device;
- Fig.7 is a General view of a device of the type "tray" with the location of the flat mirrors along the edges of the tray and with a heat exchanger in the form of two parts, each of which is in the form of a part of a volumetric cylinder;
- FIG. 8 is a general view of a solar tower device with an additional spherical concentrator and a compact heat exchanger located on the tower; in FIG. 9 is a drawing explaining the calculation of the focal length.
- Fig.9 is a drawing explaining the calculation of the focal length FP of a concave spherical or cylindrical concentrator of radius R for a beam incident on the concentrator parallel to the main optical axis at a distance "a" from it.
- the geometric configuration of the problem is clear from the figure.
- This equation is the equation of the focal zone of a spherical or cylindrical concentrator.
- the focus shift will be 3.0 cm
- at a 1.0 m
- the focus shift will be 25.4 cm.
- the maximum distance from the axis to the extreme parallel beam “a” will be 1.0 m, since the size of the planar mirror is 2x2 m
- the above calculations are performed for one main optical axis. Since we are talking about a sphere or cylinder, there can be many main optical axes from the center of a sphere or cylinder to the surface within the angular aperture of the concentrator.
- the emission of all flat mirrors 2x2 m in size to a portion of an additional spherical or cylindrical concentrator of the same size through its center within its angular aperture allows the formation of a volumetric spherical or cylindrical focal zone with a beginning at a distance of R / 2 from the additional concentrator and a depth of 25.4 cm towards the hub.
- the radiation concentration will be greatest in the R / 2 region from the side of the additional concentrator. From the center side, at a distance from the additional concentrator there will be no more concentrated radiation than R / 2. From the side of the additional concentrator, at a distance closer to it than 25.4 cm there will also be no concentrated radiation.
- the dimensions of the sites for installing flat mirrors with a diameter of 10 and up to 40 and more meters are considered.
- AT existing power plants such as "Follower plate” the diameter of the mirrors, as a rule, does not exceed 12 meters.
- the optical axes will also be from 20 to 300.
- the device operates as follows. Conventional flat mirrors 1 mounted opposite an additional spherical concentrator 2 on the working antenna field of the main concentrator 3 with a radius equal to two distances from the sphere surface to the center of the additional concentrator and oriented so that the axis of the reflected beam of each mirror passed through the center of the sphere of the additional concentrator reflect solar shine. Given that there are many flat mirrors of the main concentrator, all energy is concentrated in the focal zone of the additional spherical concentrator 4, where the heat exchanger is located.
- the heat exchanger volume will be up to 140 liters. Given that from 80 to 1200 m of effective reflective surface can work on this volume, the volumetric nature of the focal zone becomes an advantage, compared with the point in the case of a parabola. Part of the energy from flat mirrors from 18 to 25% will concentrate directly on this volume located in the focal zone, and the remaining part of the energy will be concentrated on the same volume by an additional spherical concentrator, but on the other hand.
- the claimed device can be used in power plants with mirrors in the form of a cylindrical parabolic tray.
- the main concentrator is installed in the form of a cylinder 3 with a radius of curvature equal to two distances from the surface of the cylinder to the center of the additional concentrator.
- flat mirrors 1 are installed, for example, 2x2 m in size, which are oriented so that the axis of the reflected beam passes through the cylinder axis of the additional concentrator 2.
- the additional concentrator has a cylindrical shape with a radius of 1.5 m.
- the heat exchanger 4 has also a cylindrical shape with an inner radius of 0.75 m and a thickness of up to 25.4 cm.
- the volume of liquid in the heat exchanger can be up to 150 l in 1 running meter.
- the dimensions of the additional concentrator and heat exchanger can be reduced by 2 times. Then, with the same dimensions of the general mirror system of the main concentrator, the volume of liquid in 1 linear meter of the heat exchanger will be up to 40 liters.
- the width of the main hub in the form of a cylindrical tray, consisting of flat mirrors, can be from 10 to 40 m or more. In existing projects, the width of the trays, as a rule, is no more than 6-8 m.
- the location of the flat mirrors 1 does not depend on the distance to the additional hub, all individual mirrors of the main hub can be placed in the tray not parallel to the surface of the earth, but at an angle to the horizontal equal to half the geographical latitude of the device location. In this case, solar radiation will fall perpendicular to the heat exchanger plus or minus 23 °, which will increase the efficiency of the entire system, especially in winter, and when the device is located in latitudes above 30 °.
- the heat exchanger is made in the form of a volumetric cylinder, consisting of two separate parts.
- the spherical additional concentrator will be able to collect sunlight from many mirrors of a large area in the sector up to 120 °.
