Abstract

The composite compressed gas tank has a composite structure with a cylindrical metal container and a prefabricated casing tube, especially a laminated tube. The metal container is made of aluminum alloy, brass or steel, and can be a pressurized gas bottle, can or cartridge. AN Independent claim is also included for the following: a method of manufacturing an inventive device.

Description

Die Erfindung betrifft einen Komposit-Druckgasbehälter, ein Verfahren zu dessen Herstellung und dessen Verwendung. The invention relates to a composite compressed gas container, a method for the same Manufacturing and its use.

Gase und Gasgemische werden in der Regel in Druckgasbehältern gelagert und transportiert. Die gebräuchlichsten Druckgasbehälter sind Druckgasflaschen aus Stahl und Aluminium für verdichtete, verflüssigte oder gelöste Gase mit einem maximalen Fülldruck bis 200 bar oder 300 bar. Gases and gas mixtures are usually stored in pressurized gas containers and transported. The most common pressure gas containers are made of compressed gas cylinders Steel and aluminum for compressed, liquefied or dissolved gases with one maximum filling pressure up to 200 bar or 300 bar.

Um das Gewicht von Druckgasflaschen zu verringern, werden Verbundgasflaschen (Composite Flaschen) von den Gaseherstellern eingesetzt. Verbundgasflaschen bestehen aus einem sogenannten Liner, welcher über einen wesentlichen Teil seiner Länge mit Verbundfasern aus Glas, Kohlenstoff, Aramid oder Draht umwickelt ist. Beispielsweise wird bei dem überwiegend praktizierten Naßwickelverfahren in einem gesteuerten Wickelprozeß ein Faser/Harzlaminat auf den Liner aufgetragen, das in einem nachgeschalteten Wärmebehandlungsprozess seine endgültigen Gebrauchseigenschaften erhält. Verbundgasflaschen und deren Herstellung sind z. B. in der DE 31 03 646 C2, DE 38 21 852 A1 und US 3843010 beschrieben. Die Verbundgasflaschen haben den Nachteil, daß sie durch individuelle Bewickelung der Behälter (Liner) hergestellt werden müssen, wobei die individuelle Bewickelung auf den üblichen Wickelmaschinen sehr aufwendig ist und der Prozeß mehrere, zum Teil manuell ausgeführte Arbeitsschritte erfordert, die bei jedem Behälter wiederholt werden müssen. In order to reduce the weight of compressed gas cylinders, composite gas cylinders are used (Composite bottles) used by the gas manufacturers. Composite gas cylinders consist of a so-called liner, which over a substantial part of its Length is wrapped with composite fibers made of glass, carbon, aramid or wire. For example, in the predominantly practiced wet winding process in one controlled winding process a fiber / resin laminate applied to the liner, which in a final heat treatment process its final Preserves usage properties. Composite gas cylinders and their manufacture are e.g. B. in DE 31 03 646 C2, DE 38 21 852 A1 and US 3843010. The Compound gas cylinders have the disadvantage that they can be individually wrapped Containers (liners) must be manufactured, with the individual wrapping on the usual winding machines is very complex and the process several, in part manual operations required, repeated for each container Need to become.

Ein Schwerpunkt der gegenwärtigen Entwicklung von Brennstoffzellen ist die Entwicklung von Systemen mit kleiner und mittlerer Leistung für die netzunabhängige Stromversorgung von mobilen Verbrauchern. Das Ziel sind Batterieersatzlösungen für lange Betriebszeiten bei relativ kleinen Leistungen bzw. die Bereitstellung von Energiewandlern mit unabhängig dimensionierbaren Wasserstoffspeichern. Für die Wasserstoffversorgung derartiger Systeme wird an kleine Hydridspeicher gedacht, die allerdings verschiedene Nachteile besitzen. Dazu gehören in erster Linie die hohen Materialkosten, ein sehr hohes Gewicht und eine sehr geringe Speicherdichte (etwa 1 Gew.-%). Zusätzliche Nachteile sind die Empfindlichkeit gegenüber Verunreinigungen und begrenzte Befüll- und Entladezyklen. One focus of the current development of fuel cells is Development of systems with small and medium power for the off-grid Power supply for mobile consumers. The goal is battery replacement solutions for long operating times with relatively small services or the provision of Energy converters with independently dimensionable hydrogen storage. For the Hydrogen supply of such systems is thought of small hydride storage, which have various disadvantages. This includes primarily the high material costs, a very high weight and a very low storage density (about 1% by weight). Additional disadvantages are sensitivity to Contamination and limited filling and discharging cycles.

Der Erfindung liegt die Aufgabe zugrunde, eine Verbundgasflasche zu schaffen, die wesentlich kostengünstiger hergestellt werden kann. The invention has for its object to provide a composite gas bottle, the can be produced much cheaper.

Eine weitere Aufgabe besteht in der Bereitstellung einer alternativen Wasserstoffversorgung für Brennstoffzellen. Another task is to provide an alternative Hydrogen supply for fuel cells.

Die Aufgabe wird erfindungsgemäß durch einen Druckgasbehälter mit den in Anspruch 1 beschriebenen Merkmalen gelöst. The object is achieved by a compressed gas container with the in Features described claim 1 solved.

Der umfangsverstärkte Druckgasbehälter wird dadurch hergestellt, daß über die zylindrische Länge des Liners ein Mantelrohr, insbesondere ein bereits vollständig vorgefertigtes Laminatrohr, angebracht wird. Diese Laminatrohre können sehr kostengünstig in großer Länge gefertigt werden und müssen nur noch passend zugeschnitten werden. The circumferentially reinforced pressurized gas container is manufactured in that the cylindrical length of the liner is a jacket tube, especially one already complete prefabricated laminate tube is attached. These laminate pipes can do a lot are inexpensive to manufacture in large lengths and only have to fit be tailored.

Mantelrohre sind z. B. Metallrohre, Kunststoffrohre. Bevorzugt werden Laminatrohre, die z. B. aus Fasermaterial wie Glasfaser, Kunststofffaser oder Kohlenstofffaser und einem Kunstharz (z. B. Polyesterharz oder Epoxidharz) hergestellt werden. Jacket pipes are e.g. B. metal pipes, plastic pipes. Laminate pipes are preferred, the z. B. from fiber material such as glass fiber, plastic fiber or carbon fiber and a synthetic resin (e.g. polyester resin or epoxy resin).

Nachdem das Laminatrohr über den Liner geschoben wurde müssen Liner und Laminatrohr fest verbunden werden, um den Betriebsbelastungen bzw. Druckbelastungen dauerhaft standhalten zu können. Dies wird erfindungsgemäß dadurch erreicht, daß der metallische Liner durch Innendruck so weit verformt wird, daß eine kraftschlüssige und unlösbare Verbindung zwischen dem zylindrischen Liner und dem Mantelrohr (Laminatrohr) entsteht. Das Ergebnis ist ein umfangsverstärkter zylindrischer Behälter, der nach den für Composite-Behälter geltenden Regeln der Technik ausgelegt und betrieben werden kann. After the laminate pipe has been pushed over the liner, the liner and Laminate pipe are firmly connected to the operating loads or To be able to withstand pressure loads permanently. This is according to the invention achieved in that the metallic liner is deformed by internal pressure so far, that a non-positive and permanent connection between the cylindrical liner and the jacket tube (laminate tube) is created. The result is an increased scope cylindrical container that complies with the rules of composite containers Technology can be designed and operated.
