Abstract
Anlage zur solarthermischen Stromerzeugung
Dadurch gekennzeichnet, dass sich in einem Druckbehälter (Flüssiggasbehälter) ein verflüssigtes Gas befindet. Der Druckbehälter (Flüssiggasbehälter) ist mittels einem Rohrleitungssystems an einer Pumpe angeschlossen. Diese Pumpe wiederum wird mittels eines Rohrleitungssystems an die Eintrittsseite des Primärkreislaufes eines Wärmetauschers (Verdampfer) angeschlossen. Der Wärmetauscher (Verdampfer) ist wiederum mit seinem Austritt auf der Primärseite mittels eines Rohrleitungssystems an einer Turbine angeschlossen. Die Turbine wird durch das Verdampfte Gas angetrieben und übergibt die Kraft mittels Welle an einen Generator, der ebenfalls auf der Welle des Generators befestigt ist, ab. Der Generator erzeugt elektrische Energie und gibt diese an das Stromnetz ab. Dies erfolgt bei Wechselstrom direkt oder per Transformator. Bei Gleichstromgeneratoren mittels eines Wechselrichters zwischen Generator und Stromnetz.

Characterized in that there is a liquefied gas in a pressure vessel (LPG tank). The pressure vessel (LPG tank) is connected to a pump by means of a piping system. This pump in turn is connected by means of a piping system to the inlet side of the primary circuit of a heat exchanger (evaporator). The heat exchanger (evaporator) is in turn connected to its outlet on the primary side by means of a piping system to a turbine. The turbine is driven by the vaporized gas and transfers the power by means of a shaft to a generator, which is also mounted on the shaft of the generator from. The generator generates electrical energy and delivers it to the power grid. This is done with AC directly or by transformer. For DC generators by means of an inverter between generator and power grid. The turbine, which can expand the gas is connected by piping to an expansion tank (pressure vessel). The expansion tank is connected by piping to the inlet side of the primary circuit of a heat exchanger (condenser). The condenser ...
Description
Die Erfindung betrifft den Baugruppenaufbau einer dezentralen solarthermischen Stromerzeugungsanlage mit R245fa. Das bis heute existierende Problem liegt darin, dass eine Stromerzeugung mit Solarthermie nur mit großem finanziellem und technischem Aufwand in Großanlagen zu verwirklichen war. Beispiele sind hierfür im Besonderem die Parabolspiegel-Systeme, wo ein Thermo-Öl durch gebündelte Sonnenstrahlen auf hohe Betriebstemperaturen von mehr als 400°C erwärmt wird. Mit dieser verfügbaren thermischen Energie wird meist eine Dampfturbine angetrieben.The The invention relates to the assembly structure of a decentralized solar thermal Power generation plant with R245fa. The problem that still exists today lies in the fact that a generation of solar thermal energy only with great financial and technical effort in large plants was to be realized. Examples are in particular the parabolic mirror systems, where a thermo-oil through bundled Sunbeams to high operating temperatures of more than 400 ° C is heated. With this available Thermal energy is usually driven by a steam turbine.
Dieses Verfahren ist zum einen sehr kostspielig und zum anderen mit hohem Platzbedarf verbunden. Der Betrieb solcher Kraftwerke kann ebenfalls nur rentabel in warmen Regionen erfolgen. Bereits betriebene Anlagen in Deutschland oder noch nördlicheren Regionen laufen meist mit geringer Rendite oder sogar defizitär.This Procedure is very expensive on the one hand and high on the other hand Space required. The operation of such power plants can also only profitable in warm regions. Already operated plants in Germany or even more northerly Regions usually run with low returns or even deficits.
Hier kommt unsere Entwicklung zu tragen, die bereits mit geringen Temperaturen von 65°C Strom erzeugen kann. Verwendet werden erfindungsgemäß zwei verschiedene Typen von Vakuumröhrenkollektoren. Diese sind erfindungsgemäß so konzipiert, dass eine flache Auflage ermöglicht wird. Jede einzelne Röhre selber ist entsprechend des Breitengrades vom Winkel Richtung Horizont und somit Sonne ausgerichtet. Die 1. Version der erfindungsgemäß eingesetzten Kollektoren verfügt über 20 Vakuumröhren mit einer Baulänge von ca. 2,80 m und einem Durchmesser von ca. 7 cm. Dieser Kollektor wird erfindungsgemäß hauptsächlich in den nördlichen Regionen eingesetzt. Die 2. Version der erfindungsgemäß eingesetzten Kollektoren bestehen aus 6 Vakuumröhren mit einer Baulänge von ca. 3,00 m und einem Durchmesser von ca. 12 cm. Dieser Kollektor wird erfindungsgemäß hauptsächlich in wärmeren Regionen Richtung Süden eingesetzt.Here Our development comes to bear, already with low temperatures of 65 ° C electricity can generate. According to the invention, two different types of Vacuum tube collectors. These are inventively designed that allows a flat support becomes. Every single tube itself is according to the latitude from the angle to the horizon and thus sun aligned. The 1st version of the invention used Collectors has 20 vacuum tubes with a construction length of about 2.80 m and a diameter of about 7 cm. This collector is inventively mainly in the northern one Regions used. The 2nd version of the invention used Collectors consist of 6 vacuum tubes with a length of about 3.00 m and a diameter of about 12 cm. This collector is inventively mainly in warmer Regions south used.
Die Kollektoren werden erfindungsgemäß mit einem Wasser-Glykol Gemisch durchströmt. Die erfindungsgemäße Anordnung der Kollektoren ist in einem Cluster zusammengefasst. Dieses erfindungsgemäße Cluster besteht aus 12 × 6 oder 6 × 6 oder 12 × 7 oder 6 × 7 oder 10 × 6 oder 24 × 6 oder 3 × 6 in Reihe geschalteter Kollektoren. Die Anbindung der Kollektoren erfolgt erfindungsgemäß über das sogenannte Tichelmann-Prinzip.The Collectors according to the invention with a Water-glycol mixture flows through. The inventive arrangement the collectors is grouped in a cluster. This cluster according to the invention consists of 12 × 6 or 6 × 6 or 12 × 7 or 6 × 7 or 10 × 6 or 24 × 6 or 3 × 6 in Row of connected collectors. The connection of the collectors takes place according to the invention over the so-called Tichelmann principle.
Die aufgenommene thermische Energie wird über ein Rohrleitungssystem an eine erfindungsgemäße Kaskadenspeicherbatterie mittels Wärmetauscher abgeführt. Die Kaskadenspeicherbatterie wird so angesteuert, so das auch bei niedrigen Temperaturen bereits die ankommende thermische Energie in die Wasserspeicher eingelagert werden können.The absorbed thermal energy is transmitted through a piping system to a cascade storage battery according to the invention by means of heat exchanger dissipated. The cascade storage battery is so controlled, so also at low temperatures already the incoming thermal energy can be stored in the water storage.
Die erfindungsgemäße Übernahme der thermischen Energie an den sogenannten ORC-Kreislauf erfolgt über Wärmetauscher in dem das flüssige Gas R245fa verdampft wird. Erfindungsgemäß wird dieses erhitzt und im Druck erhöht an die erfindungsgemäß verwendete Kleinturbine übergeben. Die bei Expansion nicht komplett verbrauchte thermische Energie wird mittel eines erfindungsgemäßen Economizer an das noch flüssige R245fa Gas abgegeben. Mit Hilfe eines erfindungsgemäßen Kühlsystems wird das R245fa Gas wieder komplett verflüssigt und dem Kreislauf mittel Flüssigkeitssammlers wieder zugeführt. Die angetriebene Kleinturbine treibt über ein entsprechendes Getriebe einen Generator an und speist diese so erzeugte elektrische Energie in das Stromnetz ein oder baut erfindungsgemäß im Inselbetrieb ein eigenes Stromnetz auf.The inventive acquisition The thermal energy to the so-called ORC cycle via heat exchangers in which the liquid Gas R245fa is vaporized. According to the invention this is heated and in the Pressure increased to the invention used Small turbine handed over. The thermal energy that is not completely consumed during expansion is medium by means of an economizer according to the invention the still liquid R245fa gas delivered. With the aid of a cooling system according to the invention The R245fa gas is completely liquefied again and the circuit medium liquid receiver fed again. The powered small turbine drives via a corresponding gear a generator and feeds this electrical energy generated in the power grid or builds according to the invention in island operation own Power on.
