  • 2 B : a plan view according to 1a
  • 2d : a cross section of the parabolic mirror body
  • The The invention will be described below with reference to two different embodiments represented with different parabolic levels:
  • Embodiment 1
  • According to 1a the device consists of three U-shaped steel columns 1 between which two or more parabolic mirrors 2 passing each other through mirror connectors 7 connected, on ball to store 6 are pivotally mounted. About the parabolic mirrors 2 is by means of several absorber holders 4 an absorber tube 5 arranged. Next to the central steel column 1 the parabolic mirror 2 is a drive unit 3 intended for tracking with system control.
  • The mirror connectors 7 are with Spiegelendplatten the parabolic mirror 2 connected so that the parabolic mirror 2 form a rigid unit with each other, which is held self-supporting.
  • The mirror base of the parabolic mirror 2 consists of composite plastic (GRP). The surface is covered with an aluminum sheet, which reflects the radiation. The parabolic mirror row is dependent on the angle of irradiation of the sun via a motorized control unit 10 by means of an alignment sensor 11 followed by the sun.
  • The absorber tube 4 is constructed as follows: The absorber (water) flows through a black steel tube, which is located in the vacuum of a glass tube.
  • Embodiment 2:
  • The 2a . 2 B and 2c show the device according to embodiment 1 with parabolic mirrors 2 * in longitudinal view, top view and side view.
  • According to embodiment 2 are at the beginning and end on the underside of the outer parabolic mirror 2 * Mirror end plates ( 8th ), the parabolic mirror row over the outer absorber holder ( 4 ) with the ball bearings 6 connect. In the middle of the parabolic mirror row (between the 11 mirrors) the mirror end plates ( 8th ) the parabolic mirrors 2 * via the absorber holder ( 4 ) with the drive unit 3 ,
  • The parabolic mirror row is dependent on the angle of irradiation of the sun via a motorized control unit 10 and an alignment sensor 11 Sensor tracking the sun.
  • 2d shows a cross section of the Parabolspiegelgrundkörpers 2 * with covered aluminum sheet, for the inclusion in the mirror end plate 8th notches on the back 9 has. The parabolic mirrors 2 * have parabolic shapes, which can be adjusted depending on the desired span.
  • The mirror base of the parabolic mirror 2 * is made of reinforced composite plastic (GRP).
  • A parabolic mirror can be up to 22 parabolic mirrors 2 or 2 * consist.
  • The operation of the device for obtaining thermal energy is described below:
    The parabolic mirror / solar trough produces thermal energy by focusing the solar radiation on an absorber tube. The liquid in the tube is heated and converted into steam, which can then be used for various applications in industry, for heating or for power generation.
  • For power generation, a connection of the parabolic mirror row (solar trough) with power plant components consisting of the following components is possible:
    A high and a low temperature storage
    An expansion machine with generator and electric converter
  • The Components are coordinated so that when there is solar radiation of about 10 h / d, the electrical supply also guaranteed for the night is. At lower solar powers can be a hybrid afterheating through a biomass firing system. The energy management becomes on the high temperature side by means of a classical steam drum in the form of hot water carried out. After the conversion by the converter is the most energy in Form of hot Water with a temperature of about 100-105 ° available. This can be a thermal refrigeration or a heat consumer supplied become. Next features the system over one Software interface for remote control, remote diagnostics and maintenance.
  • As a collector, a concentrating solar channel made of plastic is used. The absorber of the system can be evacuated. A selective medium absorbs the sun's rays and guarantees sufficient efficiency even at higher temperatures. The collector heats a working fluid to 250 ° C at atmospheric pressure. After this medium is heated, it flows in a closed circuit through the HT storage in which the heat is buffered in the form of hot water. By heating the water, vapor pressure is generated. As soon as enough energy is available, the energy in the form of water vapor is fed to the machine, in this relaxed and thereby cooled. The recovered electricity is transmitted in the usual way via power lines to the consumers. After the steam has been released, it is stored temporarily in another tank. Heat consumers are in turn supplied from this low-temperature storage either directly or via heat exchangers. By these consumers the residual energy (condensate energy) is removed from the steam and this condenses to liquid water. This water is returned to the HT tank by means of a pump. The water cycle is closed.
