Abstract
In der nahen Zukunft wird umweltfreundlich erzeugte Druckluft in Gebieten ohne Stromnetz, insbesondere in Schwellenländern (NIC) einen Beitrag zur Versorgung mit mechanischer Antriebsenergie leisten können. Für das Verfahren der ”Enhanced Oil Recovery (EOR)” zur Erhöhung der Ausbeute von Ölquellen müssen große Mengen von CO2 verdichtet werden. Bei Klein-Windkraftanlagen wird im unteren Leistungsbereich aus Kostengründen i. a. auf eine mechanische oder hydraulische Anpassung des Rotorblattwinkels (Pitch) an die momentane Windgeschwindigkeit verzichtet. Dies hätte im Fall eines vom Windrad angetriebenen Verdichters zur Folge, dass ersteres meist außerhalb des aerodynamisch optimalen Drehzahl-/Drehmomentbereiches arbeiten bzw. erst bei höheren Windgeschwindigkeiten anlaufen würde. Um ein gasverdichtendes Windrad immer im aerodynamisch optimalen Drehzahlbereich betreiben zu können, muss dessen Belastung der momentan verfügbaren Windgeschwindigkeit angepasst werden. Technologie für den Antrieb von Verdichtern mit Windrädern. In der Erfindung wird anstelle des variablen Pitch ein in der Leistung verstellbarer Verdichter bevorzugt nach dem Taumelscheibenprinzip verwendet. Diese Verdichter-Bauart ist mittels eines taktenden Magnetventils in der Leistung steuerbar, indem die Stellung der Taumelscheibe von der Druckdifferenz zwischen dem Ausgangsdruck und dem Druck im Kurbelgehäuse bestimmt wird. Diese Steuerbarkeit kann für ein Verfahren zur Anpassung des Lastdrehmoments ausgenutzt werden, welches in einem Steuergerät mit Computerprogramm realisiert ist.In the near future, environmentally friendly compressed air will be able to contribute to the supply of mechanical propulsion energy in non-grid areas, especially in emerging markets (NIC). The "Enhanced Oil Recovery (EOR)" method of increasing the yield of oil wells requires compressing large quantities of CO2. For small wind turbines is in the lower power range for cost reasons i. a. to a mechanical or hydraulic adjustment of the rotor blade angle (pitch) to the current wind speed omitted. In the case of a compressor driven by the wind turbine, this would mean that the former would usually operate outside of the aerodynamically optimal speed / torque range or only start at higher wind speeds. In order to operate a gas-compacting wind turbine always in the aerodynamically optimal speed range, its load must be adapted to the currently available wind speed. Technology for driving compressors with wind wheels. In the invention, instead of the variable pitch, a power variable compressor is preferably used according to the swash plate principle. This type of compressor is controllable by means of a clocking solenoid valve in the power by the position of the swash plate is determined by the pressure difference between the output pressure and the pressure in the crankcase. This controllability can be utilized for a method for adjusting the load torque, which is realized in a control unit with a computer program.
Description
In der nahen Zukunft wird umweltfreundlich erzeugte Druckluft (siehe
Für das Verfahren der ”Enhanced Oil Recovery (EOR)” zur Erhöhung der Ausbeute von Ölquellen müssen große Mengen von CO2 verdichtet werden.For the process of "Enhanced Oil Recovery (EOR)" to increase the yield of oil wells, large quantities of CO 2 must be compressed.
Die Momentanleistung einer Windkraftanlage wird außer von der augenblicklichen Windgeschwindigkeit vom aerodynamischen ”Leistungsbeiwert” bestimmt (siehe Wikipedia). Dieser ist konstruktiv bedingt und hängt von der ”Schnelllaufzahl” des Windrades ab (siehe Grafik unter
Windkraftanlagen zur Drucklufterzeugung sind seit langem bekannt, z. B. RP536663,
- 1. Bisherige Konzepte berücksichtigen mit Ausnahme von
DE3613871 - 2. Die Nutzung insbesondere von hochkomprimierter Druckluft als Zwischen-Speichermedium zur zeitverschobenen Umsetzung in elektrische Energie ist aus Aufwandsgründen nicht rentabel, da zusätzlich bei der Expansion des hochkomprimierten Gases noch Wärme zugeführt werden muss, siehe z. B.
DE 20 2014 002 179 - 3. Bei direkter lokaler Nutzung industrieüblicher Druckluft bis 10 bar z. B. in Werkstätten oder Fabriken muss zwar explizit keine Wärme zugeführt werden, jedoch ist in den hochindustrialisierten Ländern bei vorhandenem Stromnetz die Drucklufterzeugung mittels elektrisch angetriebenem Kompressor wirtschaftlicher.
- 4. Auf großen Firmengeländen z. B. in Deutschland sind zwar durchaus Druckluftnetze vorhandenen, jedoch nicht überregional.
- 5. Ein Transport in Druckbehältern via LKW als Ersatz für ein Druckluftnetz, wie er bei hochkomprimierter Druckluft dem Stand der Technik entspricht, ist bei den genannten industrieüblichen Drücken bis 10 bar wegen der großen erforderlichen Volumina nicht rentabel.
- 1. Consider previous concepts with the exception of
DE3613871 - 2. The use in particular of highly compressed air as an intermediate storage medium for the time-shifted conversion into electrical energy is not cost-effective for reasons of expense, since in addition to the expansion of the highly compressed gas still heat must be supplied, see, for. B.
DE 20 2014 002 179 - 3. For direct local use of industrial compressed air up to 10 bar z. For example, in workshops or factories, although no heat must be explicitly supplied, but in the highly industrialized countries with existing power grid, the compressed air generation by means of electrically driven compressor is more economical.
- 4. On large company premises z. B. in Germany are indeed quite compressed air networks available, but not national.
- 5. A transport in pressure vessels via truck as a substitute for a compressed air network, as it corresponds to highly compressed compressed air prior art, is not profitable at the above industrial pressures up to 10 bar because of the large volumes required.
