Abstract

The invention relates, in particular, to the efficient generation of high temperatures in the working medium by concentrating the energy available from the sun onto an absorber, in such a way that said absorber is fixed and a reflecting system which has the form of an internally mirrored hollow conical system rotates about said fixed absorber about a fixed axis in accordance with the parallactic mounting known from astronomy. Swivelling said reflecting system about said fixed axis is performed in accordance with the annual declination. In order to ensure that the entire concentrated solar energy flux impinges on the absorber surface, the surface surrounds the spatial envelope of the focal line (Fig. 2), which rotates diurnally about the fixed axis - which has a polar alignment - and is swivelled seasonally owing to the declination with respect to the fixed axis (Fig. 2). This solution avoids expensive rotary sleeve connections, with which additional problems would be expected concerning tightness and reliability. The principal possibility of application is in the generation of high temperatures, including in conjunction with high pressures, so that process heat can be generated directly or indirectly, for example for seawater desalination, or for the acceleration of fermentation gas cycles, steam power cycles or gas turbine cycles. <IMAGE>

Description

Vorrichtung zur Umsetzung von Solarstrahlung in technisch mutzbare Energie ür sehr große Reflexions/Konzentrationssysteme bei Parallel-bzw. Hintereinanderschaltung mehrerer solcher Systeme, bei denen hohe Exergie und entsprechend hohe Temperaturen erzeugt werden, ist es von Vorteil, das Reflexionssystem um einen feststehenden Absorber zu drehen. Dabei muß die trennlinie stets innerhalb des Absorbers liegen, damit der konzentrierte Energiestrom immer auf die Oberfläche des Absorbers trifft. Dies wird dadurch erreicht, daß der Absorber die orm eines Kreiszylinders besitzt, dessen Durchmesser der Brennlinie und dessen Verhältnis von Dicke d zu Durchmesser D dem Tangens der Schiefe der Ekliptik # entspricht (d/D = tan E ). Die feststehende Rotationsachse des Zylinders ist parallel zur Polachse ausgerichtet und sein geometrischer Schwerpunkt ist immer identisch mit dem Mittelpunkt der brennlinie (Fig. 1). UmUm die Rotationsachse des Kreiszylinders wird entsprechend der parallaktischen Montage das Reflexions/Konzentrationssystem dem Stundenwinkel (Rektaszension) der Sonne nachgeführt. Damit rotiert die Brennlinie täglich um die feststehende, polar ausgerichtete Achse des zylindrischen Absorbers.Device for converting solar radiation into technically usable ones Energy for very large reflection / concentration systems with parallel or Cascading several such systems, in which high exergy and correspondingly high temperatures are generated, it is advantageous to have the reflection system around a fixed one Rotate absorber. The dividing line must always lie within the absorber, so that the concentrated energy flow always hits the surface of the absorber. This is achieved in that the absorber has the shape of a circular cylinder, its diameter of the focal line and its ratio of thickness d to diameter D corresponds to the tangent of the skew of the ecliptic # (d / D = tan E). The fixed one The axis of rotation of the cylinder is aligned parallel to the polar axis and its geometric The center of gravity is always identical to the center of the focal line (Fig. 1). Um um the axis of rotation of the circular cylinder is corresponding to the equatorial assembly the reflection / concentration system corresponds to the hour angle (right ascension) of the sun tracked. This means that the focal line rotates daily around the fixed, polar one Axis of the cylindrical absorber.

Die Verschwenkung des Reflexions/Konzentrationssystems gegen seine Achse geschieht entsprechend der jährlichen Deklination (max. T 23,50 entsprechend der nordl. bzw. südl. Ekliptik) Durch die geometrische Form des Absorbers mit definierter Dicke zu Durchmesser und seiner Anordnung ist gewahrle@-stet, daß die um seine Achse rotierende Trennlinie trotz Verschwenkung infolge der Deklination zu jeder Tages-und Jahreszeit innerhalb des des Absorbers liegt, d. h. die Oberfläche umschließt die räumliche Einhüllende der rotierenden und infolge der Deklination verschwenkten Brennlinie.The pivoting of the reflection / concentration system against his Axis happens according to the annual declination (max. T 23.50 accordingly the north or southern ecliptic) Due to the geometric shape of the absorber with a defined Thickness to diameter and its arrangement is always assured that it is around its axis rotating dividing line despite pivoting as a result of the declination at every day and Season is within that of the absorber, d. H. the surface encloses the spatial envelope of the rotating and due to the declination pivoted focal line.

Damit ergibt sich zwangaläufig, daß der gesamte konzentrierte solare Energiestrom die Absorberoberfläche trifft (Fig.2). L e e r s e i t eThis inevitably results in the entire concentrated solar Energy flow hits the absorber surface (Fig. 2). R e r s e i t e
