Description
Die vorliegende Erfindung bezieht sich auf eine Einrichtung zum Umwandeln von Windenergie über dem offenen Wasser, insbesondere Ozean, in elektrische Energie gemäss dem einleitenden Teil des unabhängigen Sachpatentanspruches des Hauptpatentes ... Patentanmeldung 10 2007 019 027.3.The The present invention relates to a device for converting from wind energy over the open water, in particular ocean, into electrical energy according to the introductory one Part of the independent Patent claim of the main patent ... Patent Application 10 2007 019 027.3.
Auf vielen Teilen der Weltozeane, Weltmeere, grossen Binnenseen oder Flüssen herrschen starke bis sehr starke Winde. Diese Winde sind in ihrer Richtung und Stärke oftmals über einen längeren Zeitraum weitgehend konstant vorhanden.On many parts of the world ocean, oceans, large lakes or rivers strong to very strong winds prevail. These winds are in their direction and strength often over a longer period largely constant.
Die vorgeschlagene Einrichtung sieht eine Nutzung der Windenergie zum Antrieb von schwimmenden Wasserkraftturbinen vor und ist darüberhinaus als Verbesserung der Erfindung nach dem Hauptpatent zu verstehen. Diese Strömungsturbinen (Freistömungs-, Diffusor- oder Vortexströmungsturbinen) treiben vorzugsweise über ein mechanisches Getriebe einen oder mehrere elektrische Generatoren an. Die von diesen erzeugte elektrische Energie kann für Elektrolyseanlagen zur Erzeugung von Wasserstoff und Sauerstoff und/oder für eine Methanol- bzw. Ammoniaksyntheseanlage verwendet werden.The proposed device provides for the use of wind energy Drive from floating hydropower turbines and beyond to understand as an improvement of the invention after the main patent. These flow turbines (free-flow, Diffuser or vortex flow turbines) preferably float over a mechanical transmission one or more electric generators at. The electrical energy generated by these can be used for electrolysis systems for the production of hydrogen and oxygen and / or for a methanol or ammonia synthesis plant be used.
Die nachfolgend beschriebene erfindungsgemässe Einrichtung soll mittels gegenüber dem Hauptpatent deutlich verbesserter Nutzung von Meereswindenergie als Basisenergie in grossem Massstab zu einer erheblichen Reduzierung der CO2-Emissionen beitragen und bietet darüber hinaus die Möglichkeit zu einem Einstieg in die Erzeugung/Nutz- ung von regenerativ erzeugtem Wasserstoff respektive den Einstieg in einen CO2-Kreislaufprozess. Der vorgeschlagenen Einrichtung liegt somit die Aufgabe zugrunde, diese Windenergie verbessert zu nutzen, in elektrische Energie umzuwandeln und diese mittels Elektrolyse in chemischer Form (Wasserstoff) und/oder nach entsprechender Synthese als Methanol oder Ammoniak zu speichern. Die erfindungsgemäss vorgeschlagene Einrichtung sieht zur Lösung dieser Aufgabe eine Nutzung dieser Windenergie zum Antrieb von schwimmenden Wasserkraftturbinen vor. Diese Strömungsturbinen treiben vorzugsweise über je ein mechanisches Getriebe elektrische Generatoren an. Die erzeugte elektrische Energie wird für den Betrieb von Elektrolyseanlagen zur Wasserstoffgewinnung verwendet. Dieser regenerativ erzeugte Wasserstoff kann dann noch optional für eine Methanol- bzw. Ammoniaksynthese-anlage verwendet werden.The The device according to the invention described below is intended by means of across from the main patent significantly improved utilization of marine wind energy as a basic energy on a large scale to a considerable reduction contribute to CO2 emissions and also offers the opportunity an entry into the production / use of renewable hydrogen respectively the entry into a CO2 cycle process. The proposed Device is thus the object of this wind energy improved, convert into electrical energy and these by electrolysis in chemical form (hydrogen) and / or after corresponding synthesis as methanol or ammonia store. The inventively proposed device provides for the solution of this task use This wind energy for driving floating hydropower turbines. These flow turbines preferably float over depending on a mechanical transmission electric generators. The generated electrical energy is used for used the operation of electrolysis plants for hydrogen production. This regenerative hydrogen can then be optional for one Methanol or ammonia synthesis plant can be used.
Unter Ausnutzung der erwähnten Winde werden an einem speziell konstruierten Schwimmkörper (vereinfacht nachfolgend Energieschiff genannt) durch Segel, Schleppsegel, Drachenhöhensegel (z. B. Skysails) und/oder Flettner-Rotoren ein Vortrieb und somit eine Relativgeschwindigkeit gegenüber dem umgebenden Ozean-, Meer-, See- oder Flusswasser erzeugt. Diese Relativgeschwindigkeit zwischen dem Schwimmkörper und dem umgebenden Wasser wird dann zum Betrieb von Wasserströmungsturbinen, vorzugsweise Freistömungs-, Diffusor- oder Vortexströmungsturbinen, benutzt, welche unter dem Wasserspiegel an dem Schwimmkörper befestigt sind. Diese Wasserströmungsturbinen dienen als Antrieb für elektrische Generatoren. Bei den Diffusorströmungsturbinen handelt es sich um Turbinen, bei welchen die Turbinenräder/-flügel von einem äusseren Radialgehäuse ummantelt sind, an welches dann noch ein Diffusor analog dem Saugrohr der Turbine in einem Wasserkraftwerk nachgeschaltet ist.Under Exploitation of the mentioned Winds are made on a specially designed float (simplified hereinafter referred to as energy ship) by sail, tow, Drachenhöhensegel (eg Skysails) and / or Flettner rotors a propulsion and thus a relative speed to the surrounding ocean, Sea, lake or river water generated. This relative speed between the float and the surrounding water is then used to operate water flow turbines, preferably free-flow, Diffuser or vortex flow turbines, used, which attached to the float under the water level are. These water flow turbines serve as a drive for electric generators. The diffuser flow turbines are Turbines in which the turbine wheels / wings from an outer radial housing are sheathed, to which then a diffuser analogous to the suction pipe of the Turbine is downstream in a hydroelectric power plant.
In dem durch den Diffusor erzeugten erweiterten Bereich erfolgt dann eine verlustarme Verzögerung der Wasserströmung. Eine weitere Verbesserung der Strömungseigenschaften des Diffusors ergibt sich durch Anbringen von einem oder bis zu drei Ringspalten im Diffusorbereich bei der „Vortexströmungsturbine".In the expanded area created by the diffuser then occurs a low-loss delay the water flow. A further improvement of the flow characteristics of the diffuser results from attaching one or up to three annular gaps in the diffuser area at the "vortex flow turbine".
Durch Anbringung eines oder bis zu drei Ringspalten wird es ermöglicht, dass das das Radialgehäuse und den Diffusor aussen umströmende schnellere Wasser in den Diffusorbereich einströmt und sich durch dieses einströmende schnellere Wasser im Zusammenwirken mit der gekrümmten Mantellinie des Diffusors unter Vermeidung der Grenzschichtablösung und Wirbelbildung eine beschleunigte Randströmung ausbildet, welche die Diffusorströmung verstärkt nach aussen zieht und somit den nachgeschalteten Strömungswiderstand verringert.By Attachment of one or up to three annular gaps makes it possible that's the radial housing and the outside of the diffuser flowing around faster Water flows into the diffuser area and flows through it faster Water interacting with the curved generatrix of the diffuser while avoiding the boundary layer separation and vortex formation accelerated edge flow forms, which pulls the diffuser flow to the outside and thus reinforced the downstream flow resistance reduced.
Dem erhöhtem mechanischen sowie baulichen Aufwand einer solchen Diffusor- oder Vortexströmungsturbine gegenüber einer Freiströmungsturbine steht aber ein erhöhter Wirkungsgrad, bezogen auf den maximalen Durchmesser oder Querschnitt des Diffusors, entgegen. So beträgt der theoretisch maximal mögliche Wirkungsgrad einer Freiströmungsturbine ca. 46%. Der theoretisch maximale Wirkungsgrad einer Diffusorströmungsturbine wird in der einschlägigen Fachliteratur mit ca. 70%, bezogen auf den max. Durchmesser oder Querschnitt des Diffusors angegeben.the increased mechanical and structural complexity of such a diffuser or Vortex flow turbine across from a free-flow turbine but is an elevated one Efficiency, based on the maximum diameter or cross section of the Diffusers, contrary. So is the theoretically maximum possible Efficiency of a free-flow turbine about 46%. Theoretically maximum efficiency of a diffuser flow turbine will be in the relevant Specialist literature with approx. 70%, based on the max. Diameter or Cross section of the diffuser indicated.
Der theoretisch maximale Wirkungsgrad der Vortexturbine sollte aufgrund der verbesserten Strömungsdynamik noch um einige Prozentpunkte besser sein als der theoretisch maximale Wirkungsgrad der Diffusorströmungsturbine.Of the theoretically maximum efficiency of the Vortexturbine should be due the improved flow dynamics still be a few percentage points better than the theoretical maximum Efficiency of the diffuser flow turbine.
Die nachgeschalteten Komponenten zur Weiterverwendung des mittels der Freistömungs-, Diffusor- oder Vortexströmungsturbinen erzeugten Stromes für die Versorgung von Elektrolyseanlagen sowie der Speicherung von Wasserstoff und Sauerstoff oder der Methanol- oder Ammoniaksynthese sowie der Speicherung und des Transportes dieser regenerativ erzeugten Energieträger sind identisch mit den bereits beschriebenen Komponenten im Hauptpatent... Patentanmeldung 10 2007 019 027.3 und werden daher hier nur kurz beschrieben.The downstream components for further use of the generated by means of the free-flow, diffuser or Vortexströmungsturbinen Electricity for the supply of electrolysis systems and the storage of hydrogen and oxygen or the methanol or ammonia synthesis and the storage and transport of these regeneratively produced energy sources are identical to the components already described in the main patent ... Patent Application 10 2007 019 027.3 and are therefore here only briefly described.
Auf dem Energieschiff (Schwimmkörper) befinden sich Elektrolyseanlagen, Behälter für das elektrolysefähige Wasser, Kompressoren für die Gasverdichtung sowie Druckbehälter zur Aufnahme der erzeugten Wasserstoff- und Sauerstoffgase. Alternativ ist auch die Speicherung des erzeugten Wasserstoffes auf dem Schwimmkörper in Form von flüssigem Methanol oder Ammoniak möglich.On the energy ship (float) are electrolysis plants, tanks for the electrolyzed water, Compressors for the gas compression and pressure vessel for receiving the generated Hydrogen and oxygen gases. Alternatively, the storage the generated hydrogen on the float in the form of liquid methanol or ammonia possible.
Optional ist auch eine direkte Speicherung der erzeugten elektrischen Energie auf dem Energieschiff mittels ausreichend dimensionierter Akkumulatoren möglich. Für die Methanolsynthese würde ein Speicher für flüssiges CO2 erforderlich sowie eine entsprechend ausgelegte Methanolsyntheseanlage. Alternativ ist auch eine Ammoniaksynthese möglich. Ferner kann auch der Sauerstoff grundsätzlich in flüssiger Form gespeichert werden.optional is also a direct storage of the generated electrical energy on the power ship by means of adequately dimensioned accumulators possible. For the Methanol synthesis would a memory for liquid CO2 required and a correspondingly designed methanol synthesis plant. alternative is also an ammonia synthesis possible. Further can also be the oxygen in principle in liquid Form will be saved.
Die aus einem oder mehreren Schwimmkörpern bestehenden Energieschiffe sollten so konstruiert sein, dass ihr(e) Schwimmkörper möglichst wenig Strömungswiderstand aufweist(en) und könnten z. B. als Katamarane, Trimarane oder mit fünf Schwimmkörpern konstruiert sein. Grosse Segel, Schleppsegel, Drachenhöhensegel (z. B. Skysails) und/oder Flettner-Rotoren ziehen oder treiben das Energieschiff durch das umgebende Wasser und treiben dabei die als Freiströmungs-, Diffusor- oder Vortexströmungsturbinen konzipierten Wasserturbinen an.

des Diffusor-Segmentes
Die Wasserströmungsturbinen wirken neben dem Strömungswiderstand des Schwimmkörpers dabei als Gegenkraft zu dem Segelantrieb/Antrieb der Flettner-Rotoren. Aufgrund physikalischer Gesetzmässigkeiten steigt dabei die Leistung der Wasserströmungsturbinen überproportional mit der Geschwindigkeit des Energieschiffes.The Water current turbines act in addition to the flow resistance of the float as a counterforce to the sail drive / drive of the Flettner rotors. Due to physical laws The performance of the water flow turbines increases disproportionately with the speed of the energy ship.
