Description

Die Erfindung betrifft eine Speichervorrichtung zum Speichern eines Mediums, insbesondere eines unter Druck stehenden Mediums, wie beispielsweise verflüssigtes Erdgas, aufweisend einen ein- oder mehrwandigen Speicherbehälter.The The invention relates to a storage device for storing a Medium, in particular a pressurized medium, such as liquefied Natural gas, comprising a single or multi-walled storage tank.

Gattungsgemäße Speichervorrichtungen sind aus dem Stand der Technik hinlänglich bekannt. Entsprechend ihrem Anwendungszweck werden derartige Speichervorrichtungen ein- oder mehr-, vorzugsweise doppelwandig ausgeführt. insbesondere bei der Speicherung tiefkalter verflüssigter Gase oder von verflüssigtem Erdgas ist zwischen den Wandungen der Speichervorrichtungen – also zwischen dem Außen- und dem Innenbehälter – eine Isolierung, vorzugsweise eine Perlite-Isolierung vorgesehen.Generic storage devices are from the prior art known. According to their application, such storage devices one or more, preferably double-walled executed. especially at storing cryogenic liquefied Gases or liquefied Natural gas is between the walls of the storage devices - ie between the outside and the inner container - an insulation, preferably a perlite insulation provided.

Gattungsgemäße Speichervorrichtungen sind vor dem ersten Befüllen kalt zu fahren und nach erfolgter Befüllung und Entnahme des gespeicherten Mediums kalt zu halten. Dieses Kaltfahren bzw. Kalthalten wird bisher realisiert, indem beim erstmaligen Kaltfahren sowie beim Kalthalten ein geeignetes Medium, beispielsweise verflüssigtes Erdgas oder verflüssigter Stickstoff, in die Speichervorrichtung bzw. den Speicherbehälter geführt werden. Mittels der bekannten Kaltfahr- bzw. Kalthalteverfahren ist jedoch kein gleichmäßiges Abkühlen der Speichervorrichtung bzw. des Speicher(innen)behälters realisierbar. Dies hat zur Folge, dass die Speichervorrichtung bzw. der Speicher(innen)behälter ungleichmäßig stark belastet und gekühlt werden.Generic storage devices are before the first filling to drive cold and after filling and removal of the stored medium to keep cold. This cold running or cold holding is realized so far, by providing a suitable medium during the first cold-run and during cold-holding, for example liquefied Natural gas or liquefied Nitrogen, are led into the storage device or the storage container. However, by means of the known cold-running or cold-holding methods no uniform cooling of the Storage device or the storage (inside) container realized. this has As a result, the storage device or the storage (inner) container unevenly strong charged and cooled become.

Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Speichervorrichtung zum Speichern eines Mediums anzugeben, bei der die vorgenannten Nachteile vermieden werden können.task The present invention is a generic storage device to specify for storing a medium, in which the aforementioned Disadvantages can be avoided.

Erfindungsgemäß wird nun innerhalb des Speicherraumes der erfindungsgemäßen Speichervorrichtung ein Nebelvorhang generiert, der wiederum eine Konvektionswalze erzeugt und aufrecht erhält. Aufgrund dieser Konvektionswalze und des daraus resultierend hohen Wärmeüberganges zwischen dem versprühten Medium und der Innenwandung der Speichervorrichtung bzw. des Speicher(innen)behälters kann nunmehr eine gleichmäßige Abkühlung der Speichervorrichtung bzw. des Speicher(innen)behälters realisiert werden.According to the invention will now within the storage space of the storage device according to the invention Mist curtain generated, which in turn generates a convection roll and maintains. Because of this convection roller and the resulting high Heat transfer between the sprayed Medium and the inner wall of the storage device or the storage (inner) container can now a uniform cooling of the storage device or the storage (inner) container will be realized.

Die zur Anwendung kommenden Düsen sind vorzugsweise sog. Nebeldüsen, die es ermöglichen, das für das Kaltfahren und Kalthalten der Speichervorrichtung verwendete Medium derart einzudüsen, dass feine Nebeltropfen entstehen.The for use coming nozzles are preferably so-called fog nozzles, that make it possible for the Cold running and cold holding the storage device used medium to inject in such a way that fine fog drops arise.

Entsprechend der Form des Speicherraumes der erfindungsgemäßen Speichervorrichtung ist eine Anordnung der Düsen zu wählen, die es ermöglicht, dass sich zwischen der Außenwand des Nebelvorhanges und der Innenwand des Speicherraumes wenigstens eine ausreichend große Konvektionswalze ausbildet.Corresponding the shape of the storage space of the storage device according to the invention is a Arrangement of the nozzles to choose, which makes it possible that is between the outer wall the fog curtain and the inner wall of the storage space at least a big enough one Convection roller trains.
