Abstract
Description
Die vorliegende Erfindung betrifft eine Meerwasserentsalzungsanlage mit Stickstoffdruckgas die mit Hilfe von flüssigem Stickstoff, der im Meerwasser mit Hilfe von wenigstens einem Wärmetauscher verdampft wird, den notwendigen Gasdruck zum Beaufschlagen des Meerwassers in der Umkehrosmoseanlage ermöglicht und wobei dadurch der Einsatz von jeglichen Pumpen in der Meerwasserentsalzungsanlage entfällt. Somit wird das Reinigen von Flüssigkeiten durch die Umkehrosmose ohne jegliche mechanische Pumpe ermöglicht.The present invention relates to a seawater desalination plant with nitrogen gas Help of liquid Nitrogen in sea water with the help of at least one heat exchanger is evaporated, the gas pressure necessary to pressurize the sea water in the reverse osmosis system and thereby the use of any pumps in the desalination plant eliminated. Thus cleaning liquids thanks to the reverse osmosis without any mechanical pump.
Herkömmliche Umkehrosmoseanlagen benötigen mechanische Pumpen um den notwendigen Druck, Beispielsweise zur Trinkwassergewinnung, in der Flüssigkeit zu erhalten. Dies führt zu Verschleiß in den mechanischen Teilen und es bedarf einer ständigen Wartung der mechanischen Teile. Des Weiteren sind hier Pumpenelement notwendig die bei großen Anlagen sehr geräuschintensiv sind und somit eine Beeinträchtigung durch Geräusche in der Umgebung nach sich ziehen. Höchstdrücke mit über 15 bar führen in den meisten Fällen zu einem sehr hohen Energieverbrauch da extrem hohe Pumpenleistungen erforderlich sind. Aus dem derzeitigen Stand der Technik sind solche Meerwasserentsalzungsanlage mit Stickstoffdruckgas nicht bekannt.Conventional reverse osmosis systems need mechanical pumps to the necessary pressure, for example Drinking water extraction, in the liquid to obtain. this leads to to wear in the mechanical parts and it requires constant maintenance of the mechanical Parts. Furthermore, pump elements are required here, which are required for large systems very noisy are and therefore an impairment through noises in the area. Maximum pressures of over 15 bar lead to most cases very high energy consumption due to extremely high pump outputs required are. These are from the current state of the art Sea water desalination plant with nitrogen gas not known.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Meerwasserentsalzungsanlage mit Stickstoffdruckgas bereit zu stellen, bei dem die zuvor dargestellten Nachteile vermieden werden.The present invention lies hence the task of having a desalination plant To provide nitrogen gas, at which the previously shown Disadvantages are avoided.
Der Aufbau der Meerwasserentsalzungsanlage mit Stickstoffdruckgas wird wie folgt dargestellt. Flüssiger Stickstoff wird in wenigstens einem geeigneten Flüssigstickstofftank gespeichert und bevorratet. Die Entnahme von flüssigem Stickstoff erfolgt über wenigstens eine Leitung für flüssigen Stickstoff. Dieser flüssige Stickstoff wird nun einer Flüssigstickstoffverdampfereinheit zugeführt, die über einen Wärmetausch durch die im Meerwasser gespeicherte Wärme den flüssigen Stickstoff verdampft. Das somit entstandene Stickstoffdruckgas wird nun über wenigstens eine Stickstoffdruckgasleitung dem Meerwassertank der Umkehrosmoseanlage zugeführt. Hier wird mit dem anliegenden Stickstoffgasdruck das Meerwasser beaufschlagt, und es wird somit der notwendige Druck zur Funktion der Umkehrosmoseanlage bereitgestellt. Über ein ständiges Nachverdampfen von flüssigem Stickstoff wird das in der Umkehrosmose austretende Meerwasser ausgeglichen. Somit bleibt der Arbeitsdruck für die Umkehrosmoseanlage ständig erhalten. Ist nun das Meerwasser fast vollständig ausgetreten, so wird über eine Regeleinheit die Zufuhr von Stickstoffdruckgas in den Meerwassertank der Umkehrosmoseanlage gesperrt und es erfolgt eine Abnahme des Restgases in einen so genannten Pufferspeicher. Überschüssiges Restgas mit zu niedrigem Druck wird abgelassen. Der Meerwassertank der Umkehrosmoseanlage wird auf das neue mit frischem Meerwasser selbstständig gefüllt und wieder verschlossen, wobei aber hier das Restgas im Pufferspeicher als Energiequelle dienen kann, wenn sich beispielsweise der Meerwassertank außerhalb des Meeres befinden sollte. Der zuvor Abgeregelte Zulauf von Stickstoffdruckgas wird wieder geöffnet und es beginnt einer neuer Zyklus von Meerwasserentsalzung in der Umkehrosmoseanlage.The construction of the desalination plant with nitrogen gas is shown as follows. Liquid nitrogen is stored in at least one suitable liquid nitrogen tank and stocked. Liquid nitrogen is removed via at least a line for liquid Nitrogen. This fluid Nitrogen is now a liquid nitrogen evaporator unit supplied the above a heat exchange due to the heat stored in the sea water, the liquid nitrogen evaporates. The nitrogen pressure gas thus created is now at least a nitrogen gas line to the seawater tank of the reverse osmosis system fed. Here is the sea water with the nitrogen gas pressure pressurized, and it becomes the necessary pressure to function of the reverse osmosis system. Via constant re-evaporation of liquid nitrogen the sea water escaping in the reverse osmosis is balanced. So the working pressure remains for the reverse osmosis system constantly receive. If the sea water has now almost completely escaped, then a Control unit the supply of nitrogen gas in the sea water tank the reverse osmosis system is blocked and the Residual gas in a so-called buffer storage. Excess residual gas with too low Pressure is released. The sea water tank of the reverse osmosis system is automatically filled with fresh sea water and closed again, but here the residual gas in the buffer storage serves as an energy source can, for example, if the seawater tank is outside of the sea. The previously regulated inflow of nitrogen pressure gas will open again and a new cycle of desalination begins Reverse osmosis system.
Die zuvor dargestellte Problemstellung wurde somit umfassend gelöst.The problem presented above was thus fully solved.
In einer Weiterbildung der erfindungsgemäßen Meerwasserentsalzungsanlage mit Stickstoffdruckgas wird diese mit Photovoltaikstrom und oder Windenergie und oder Wellenenergie und oder Solarenergie selbstständig flüssigen Stickstoff und oder flüssige Luft in einer vorgeschalteten Verflüssigungsanlage erzeugen, um somit autark ständig Meerwasser entsalzen zu können.In a development of the seawater desalination plant according to the invention with nitrogen gas, this is with photovoltaic electricity and or wind energy and or wave energy and or solar energy independently liquid nitrogen and or liquid Generate air in an upstream liquefaction plant to thus self-sufficient all the time Desalination of sea water.
