Description

Druckbehälterpressure vessel

Die vorliegende Erfindung betrifft einen Druckbehälter zur Speicherung fester, flüssiger und/oder gasförmiger Medien, zusammengesetzt aus einem Rohr aus Faserkunststoffverbund und Deckeln, die einen zur Speicherung des Mediums vorgesehenen Hohlraum umschließen und über mindestens einem Anschluß zum Be- und/oder Entladen des Behälters verfügen.The present invention relates to a pressure vessel for storing solid, liquid and/or gaseous media, composed of a tube made of fiber-plastic composite and lids which enclose a cavity provided for storing the medium and have at least one connection for loading and/or unloading the vessel.

Feste, flüssige und/oder gasförmiger Medien werden üblicherweise in Druckbehältern transportiert, die eine geeignete Diffusionsdichtigkeit gegen Verflüchtigung des Mediums aufweisen und den mechanischen Beanspruchungen durch Innen- bzw. Außendruck sowie den weiteren mechanischen, physikalischen und chemischen Belastungen standhalten.Solid, liquid and/or gaseous media are usually transported in pressure vessels that have a suitable diffusion tightness against evaporation of the medium and can withstand the mechanical stresses caused by internal or external pressure as well as other mechanical, physical and chemical stresses.

Druckbehälter aus Faserkunststoffverbunden sind bekannt und es existiert eine Vielzahl an Patenten. Als Beispiel sei das Europa Patent EP0810081 A1 &ldquor;Pressure Vessel and Method of Manufacturing Same" genannt. Hierbei wird beschrieben wie eine geschlossene Hüllschicht, die aus einem Kunststoff besteht, im Faserwickelverfahren mit einem Faserkunststoffverbund umhüllt wird. Ein ähnliches Behälterprinzip wird im Europapatent EP0333013 A1 &ldquor;Pressure Vessels" beschrieben. Auch in diesem Falle wird eine Hüllschicht mit Fasern derart umgeben, daß die Verstärkungshülse den mechanischen Beanspruchungen standhält. Das internationale Patent WO 92/20954 &ldquor;glass-fibre-reinforced plastic container, method and apparatus for manufacturing such container" beschreibt einen glasfaserverstärkten Behälter und ein Verfahren zu dessen Herstellung, wobei sich der Behälter aus zwei Halbschalen zusammensetzt, die im zylindrischen Bereich durch Verkleben miteinander Verbunden werden. Andere bekannte Bauarten sehen den Einsatz von Hülsen aus Faserkunststoffverbund vor, die in Teilbereichen an einer Hüllschicht angeordnet sind wobei die Faserausrichtung der Hülse vornehmlich in Umfangsrichtung erfolgt. Die Hüllschicht nimmt dabei die entstehenden Kräfte in Längsachse des Behälters auf während die Hülse die Kräfte in Umfangsrichtung des Behälters aufnimmt. Die Patentanmeldung DE19832 145A1 sieht Deckel aus Faser-Kunststoff-Verbund vor, wobei diese nach innen in den Behälterraum gewölbt sind. Weiterhin sind Behälterbündel bekannt, die sich aus mehreren Einzelbehältern zusammensetzen, wobei die einzelnen Behälter auf einer durchgängigen Rohrleitung, nach dem Perlenkettenprinzip, aufgereiht und untereinander verbunden sind, indem die verbindende Rohrleitung in den Behälterinnenräumen durch Öffnungen das Be- und Entladen der Behälter ermöglicht.Pressure vessels made of fiber-plastic composites are well known and there are a large number of patents. One example is the European patent EP0810081 A1 "Pressure Vessel and Method of Manufacturing Same". This describes how a closed covering layer made of plastic is covered with a fiber-plastic composite using a fiber winding process. A similar container principle is described in the European patent EP0333013 A1 "Pressure Vessels". In this case too, a covering layer is surrounded by fibers in such a way that the reinforcing sleeve can withstand the mechanical stresses. The international patent WO 92/20954 "glass-fibre-reinforced plastic container, method and apparatus for manufacturing such container" describes a glass fibre reinforced container and a method for its manufacture, whereby the container is made up of two half-shells which are bonded together in the cylindrical area by gluing. Other known designs provide for the use of sleeves made of fibre-plastic composite, which are arranged in partial areas on a covering layer, whereby the fibre alignment of the sleeve is mainly in the circumferential direction. The covering layer absorbs the forces arising in the longitudinal axis of the container, while the sleeve absorbs the forces in the circumferential direction of the container. The patent application DE19832 145A1 provides for lids made of fibre-plastic composite, whereby these are curved inwards into the container space. Furthermore, container bundles are known which are made up of several individual containers, whereby the individual containers are lined up on a continuous pipe, according to the pearl necklace principle, and are connected to one another by the connecting Piping in the interior of the containers allows loading and unloading of the containers through openings.

Alle bisher bekannten Bauarten von Druckbehältern sind entweder zu aufwendig und damit zu kostenintensiv in der Herstellung, halten den Anforderungen bezüglich Dichtigkeit oder mechanischer Beanspruchungen nicht stand, sind zu schwer oder weisen optisch ungenügende Außenoberflächen auf.All previously known pressure vessel designs are either too complex and therefore too costly to manufacture, do not meet the requirements in terms of tightness or mechanical stress, are too heavy or have visually inadequate external surfaces.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Druckbehälter derart weiterzubilden, daß die im Stand der Technik genannten Nachteile vermieden werden. Insbesondere soll ein Behälter mit geringem Eigengewicht geschaffen werden, der hohen mechanischen Beanspruchungen standhält und kostengünstig herzustellen ist, sowie eine optisch ansprechende Außenoberfläche bietet und die Möglichkeit der Anbringung von Anschlüssen an nahezu beliebigen Punkten ermöglicht. Weiterhin gilt es eine Konstruktion mit variablem Volumen zu finden. Die Erfindung soll gegenüber dem Stand der Technik Druckbehälter derart weiterbilden, daß eine hohe Marktakzeptanz bei geringem Behältergewicht, hoher Variabilität und rationeller Fertigung erreicht wird. Weiterhin soll sich der Behälter zu Behälterbündeln zusammenstellen lassen, wobei die einzelnen Behälter mit einer durchgängigen Rohrleitung (Perlenkettenprinzip) untereinander verbunden sind und diese Rohrleitung in den Behälterinnenräumen durch Öffnungen das Be- und Entladen der Behälter ermöglicht.The invention is therefore based on the object of developing a pressure vessel in such a way that the disadvantages mentioned in the prior art are avoided. In particular, a vessel with a low dead weight is to be created that can withstand high mechanical stresses and is inexpensive to manufacture, as well as offering a visually appealing outer surface and allowing connections to be attached at almost any point. A design with variable volume is also to be found. The invention is to develop pressure vessels in comparison with the prior art in such a way that high market acceptance is achieved with low vessel weight, high variability and efficient production. Furthermore, the vessel should be able to be put together to form container bundles, with the individual vessels being connected to one another by a continuous pipe (pearl chain principle) and this pipe enabling the containers to be loaded and unloaded through openings in the interior of the vessel.

Die Aufgabe wird gemäß einem Aspekt der Erfindung dadurch gelöst, daß ein Rohr aus Faserkunststoffverbund mit thermoplastischer Matrix und zwei Deckel derart miteinander verbunden werden, daß sie einen zur Speicherung des Gases vorgesehenen Hohlraum umschließen, und daß das Rohr aus Fasern und einer thermoplastisch basierten Matrix besteht.The object is achieved according to one aspect of the invention in that a pipe made of fiber-plastic composite with a thermoplastic matrix and two covers are connected to one another in such a way that they enclose a cavity provided for storing the gas, and in that the pipe consists of fibers and a thermoplastic-based matrix.

Das Rohr wird an den Enden jeweils mit einem Deckel verschlossen, wobei der auf diese Weise umschlossene Hohlraum über mindestens einen Anschluß zum Be- und/oder Entladen des Behälters verfügt. Der Deckel ist nach außen gewölbt, vorzugsweise aber nicht ausschließlich metallisch. Das Rohr besteht überwiegend aus einem faserverstärkten thermoplastischen Kunststoff, und die metallischen Deckel sind durch einen Sicherungsring formschlüssig mit dem Rohr verbunden. Bevorzugte Geometrien des Rohres ist unter anderem - jedoch nicht ausschließlich - eine Kreisgeometrie. Erfindungsgemäß ist Betriebsdruck der im Behälter gespeicherten Medien unbeschränkt, vorzugsweise 1 bis 1000 MPa (10 bis 10.000 bar) betragen. Der entsprechende Berstdruck entspricht dabei dem mit 1,1 bis 4 multiplizierten Wert des jeweiligen Betriebsdruckes.The pipe is closed at each end with a lid, whereby the cavity enclosed in this way has at least one connection for loading and/or unloading the container. The lid is curved outwards, preferably but not exclusively metallic. The pipe consists predominantly of a fibre-reinforced thermoplastic, and the metallic lids are positively connected to the pipe by a locking ring. Preferred geometries of the pipe include - but are not limited to - a circular geometry. According to the invention, the operating pressure of the media stored in the container is unlimited, preferably 1 to 1000 MPa (10 to 10,000 bar). The corresponding bursting pressure corresponds to the value of the respective operating pressure multiplied by 1.1 to 4.
