Abstract

It is shown in this invention how a steam generating plant can be constructed by means of the roof tiles. For this purpose a liquid must flow through pipes which bear against the roof tiles in order to take up heat, and has a boiling point so low that it evaporates before it has reached the roof ridge, or before it has reached the upper openings of the pipes. The vapour must however pass through a coil situated in the pipe, so that it has a high density at the upper pipe openings when coming out of these. Here it impinges on vanes which are attached to a shaft transverse to the flow direction of the evaporator liquid (located on the shaft) and pushes the vanes backwards, thus turning the shaft. This rotation is transmitted, for current production, to a generator outside the closed circulation of the evaporator liquid. A coolant flows underneath the shaft through pipes provided with cooling fins, in order to condense this steam again so that the circulation can begin anew.

Description

Die Erfindung zeigt, wie man Solar-Dachpfannen als Energiefänger für ein Dampfkraftwerk nutzen kann. Dampfkraftwerke werden bisher beschickt mit Wasser, obwohl es Flüssigkeiten gibt, welche bei erheblich niedrigeren Temperaturen zu sieden vermögen. Die Temperatur von Dachpfannen ist etwa dreimal so hoch als die Lufttemperatur bei Sonnenschein, nicht bei Bewölkung. Bei + 10°C sind Dachpfannen an lauen Märztagen schon + 30°C warm, dies reicht aus, um eine niedrigsiedende Flüssigkeit zum Sieden zu bringen. Es wird darum erfindungsgemäß vorgeschlagen, dass durch Rohre, welche an die Solar-Dachpfannen anliegen, eine so niedrig siedende Flüssigkeit geschickt wird, dass diese mit Hilfe der von den Solar-Dachpfannen gespeicherten Sonnenwärme verdampft. Um diese Verdampfungsenergie zu nutzen, muß die niedrigsiedende Flüssigkeit mit der Dachneigung erfindungsgemäß aufwärts steigen können statt quer zur Dachneigung zu strömen, mit Druckventil gesichert. Quer zur Strömungsrichtung der aufwärts strömenden verdampften Substanz ist erfindungsgemäß eine drehbare Achse mit Schaufeln zu lagern, auf welche der Dampf einwirken kann zur Erzeugung der Drehung der Achse, welche nach außerhalb des geschlossenen Kreislaufs der Verdampfersubstanz auf einen Generator zur Stromerzeugung einwirken soll. Ein Stück weit unterhalb der sich drehenden Achse mit den Schaufeln laufe erfindungsgemäß ein Kühlrohr mit Kühlrippen in gleicher Richtung wie die Achse, um die verdampfte Substanz wieder zu kondensieren. Die Rohre, welche von den Solar-Dachpfannen die Energie abnehmen, sollen erfindungsgemäß Gewinderohre sein mit derartig gestaltetem Gewinde, dass dadurch die Wärme übertragen, die Substanz verdampfen und sich nicht ausdehnen kann zur Druckerhöhung. Vorteil: Solar-Verstromung.The invention shows how you can use solar roof tiles as an energy catcher for a steam power plant. Steam power plants have so far been charged with water, although there are liquids that can boil at significantly lower temperatures. The temperature of roof tiles is about three times higher than the air temperature in sunshine, not when it is cloudy. At + 10 ° C, roof tiles are already + 30 ° C warm on mild March days, which is enough to bring a low-boiling liquid to the boil. It is therefore proposed according to the invention that a liquid with such a low boiling point is sent through pipes which are in contact with the solar roof tiles that it evaporates with the help of the solar heat stored by the solar roof tiles. In order to use this evaporation energy, according to the invention, the low-boiling liquid must be able to rise upwards with the roof slope instead of flowing across the roof slope, secured with a pressure valve. According to the invention, a rotatable shaft with blades is to be mounted transversely to the direction of flow of the upwardly flowing vaporized substance, on which the steam can act to generate the rotation of the shaft, which is to act on a generator to generate electricity outside the closed circuit of the vaporized substance. According to the invention a cooling tube with cooling fins runs a little way below the rotating axis with the blades in the same direction as the axis in order to condense the vaporized substance again. The pipes which take the energy from the solar roof tiles should, according to the invention, be threaded pipes with a thread designed in such a way that the heat can thereby be transferred, the substance can evaporate and not expand to increase the pressure. Advantage: solar power generation.
