Abstract

The invention relates to the partial or complete use of a pressurized gas cylinder known per se for compressed, liquefied or dissolved gases as a liner for a composite cylinder. This enables production costs of a composite cylinder to be reduced by 1/3 when compared to the costs arising from the production of a new composite cylinder using current manufacturing technologies.

Description

Teilweise oder vollständige Verwendung einer an sich bekannten Druckgasflasche für verdichtete, verflüssigte oder gelöste GasePartial or complete use of a known compressed gas cylinder for compressed, liquefied or dissolved gases
Die Erfindung betrifft die teilweise oder vollständige Verwendung einer an sich bekannten Druckgasflasche für verdichtete, verflüssigte oder gelöste Gase.The invention relates to the partial or complete use of a known compressed gas bottle for compressed, liquefied or dissolved gases.
Gase und Gasgemische werden in der Regel in Druckgasbehältern gelagert und transportiert. Nach der Druckbehälterverordnung sind dies Behälter, in denen bei 15°C ein höherer Überdruck als 1 bar entstehen kann. Über den Stand der Sicherheitstechnik hinsichtlich Werkstoff, Herstellung, Berechnung, Ausrüstung, Kennzeichnung, Prüfung und Betrieb der Druckgasbehälter sowie Errichtung, Prüfung und Betrieb der Füllanlagen geben die technischen Regeln Druckgase (TRG) Auskunft. Die TRG unterscheiden Gase und Gasgemische nach ihrem chemischen und physikalischen Verhalten und legen die zu verwendenden Druckgasbehälter einschließlich ihrer Ausrüstungsteile, deren Prüffristen, die Füllfaktoren und Fülldrücke fest.Gases and gas mixtures are usually stored and transported in pressurized gas containers. According to the Pressure Vessel Ordinance, these are vessels in which a higher pressure than 1 bar can arise at 15 ° C. The technical rules for compressed gases (TRG) provide information on the state of safety technology with regard to material, manufacture, calculation, equipment, labeling, testing and operation of the compressed gas tanks as well as the construction, testing and operation of the filling systems. The TRG differentiate gases and gas mixtures according to their chemical and physical behavior and determine the pressurized gas containers to be used, including their equipment, their test periods, the filling factors and filling pressures.
Die gebräuchlichsten Druckgasbehälter sind Druckgasflaschen aus Stahl und Aluminium für verdichtete, verflüssigte oder gelöste Gase mit einem maximalen Flülldruck bis 200 bar. Zunehmend werden von den Anwendern Druckgasbehälter mit einem maximalen Fülldruck bis 300 bar verlangt. Diese 300 bar- Druckgasbehälter werden ebenfalls aus Stahl oder Aluminium gefertigt. Für besondere Anwendungsfälle kommt auch korrosionsbeständiger Edelstahl (DE 37 36 579 A1) zum Einsatz.The most common pressurized gas containers are pressurized gas cylinders made of steel and aluminum for compressed, liquefied or dissolved gases with a maximum filling pressure of up to 200 bar. Pressurized gas containers with a maximum filling pressure of up to 300 bar are increasingly required by users. These 300 bar pressure gas tanks are also made of steel or aluminum. Corrosion-resistant stainless steel (DE 37 36 579 A1) is also used for special applications.
Um das Gewicht derartiger 300 bar-Druckgasflaschen zu verringern, werden in neuerer Zeit Verbundgasflaschen (Composite Flaschen) von den Gaseherstellern eingesetzt. Verbundgasflaschen bestehen aus einem natlosen Metallliner, welcher über einen wesentlichen Teil seiner Länge mit Verbundfasern aus Glas, Kohlenstoff, Aramid oder Draht umwickelt ist. Unter Aramid werden organische Fasern aus poly phenylene terphlalamid verstanden, welche Kevlar und Twaron einschließen. Aramid- und Kohle-Fasern sind leichter als Fasern aus Glas, mit gleichen oder höheren Festigkeitseigenschaften und guter Schlagzähigkeit.In order to reduce the weight of such 300 bar compressed gas cylinders, composite gas cylinders have recently been used by the gas manufacturers. Composite gas cylinders consist of a natural metal liner, which is wrapped over a substantial part of its length with composite fibers made of glass, carbon, aramid or wire. Aramid means organic fibers made of polyphenylene terphlalamide, which include Kevlar and Twaron. Aramid and carbon fibers are lighter than glass fibers, with the same or higher strength properties and good impact strength.
Derartige Verbundgasflaschen sind in der Herstellung teuer. Hinzu kommt, daß bei Abfüllung aller heute technisch möglichen Gasarten in 300 bar Druckgasflaschen ein hohes Entsorgungspotential für gebrauchte 200 bar-Druckgasflaschen besteht.Such composite gas cylinders are expensive to manufacture. In addition, there is a high disposal potential for used 200 bar compressed gas cylinders when filling all types of gas that are technically possible today in 300 bar compressed gas cylinders.
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 that can be manufactured much cheaper.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 , 2, 3, 9, 11 und 12 gelöst.This object is achieved by the features of claims 1, 2, 3, 9, 11 and 12.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous developments of the invention are specified in the subclaims.
Es hat sich überraschend gezeigt, daß durch die erfindungsgemäße Verwendung einer an sich bekannten Druckgasfiasche, insbesondere einer an sich bekannten Druckgasflasche aus Metall, vorzugsweise einer Druckgasflasche aus Stahl, für verdichtete, verflüssigte oder gelöste Gase als Liner für eine Verbundgasflasche die Kosten für die Herstellung der Verbundgasflasche auf ca. 1/3 verringert werden können. Die an sich bekannte Druckgasflasche hat einen Gasinhalt von 1 bis 150 Liter bei einem Fülldruck von 150 bis 200 bar. Dabei können viele im Umlauf befindliche Druckgasflaschen weiterverwendet werden, die sonst entsorgt, d. h. verschrottet werden müßten. Dies spart Ressourcen und Emmissionen, da weniger Druckgasflaschen hergestellt werden müssen.It has surprisingly been found that the use according to the invention of a compressed gas bottle known per se, in particular a known compressed gas bottle made of metal, preferably a compressed gas bottle made of steel, for compressed, liquefied or dissolved gases as liners for a compound gas bottle, the costs for the production of the Compound gas bottle can be reduced to about 1/3. The known compressed gas bottle has a gas content of 1 to 150 liters at a filling pressure of 150 to 200 bar. Many compressed gas cylinders in circulation that are otherwise disposed of can be used. H. would have to be scrapped. This saves resources and emissions because fewer compressed gas cylinders have to be manufactured.
Die an sich bekannte Druckgasflasche, wie sie von den Gaseherstellern zum Transport der Gase und Gasgemische in flüssiger oder gelöster Form eingesetzt wird, muß nur über einen wesentlichen Teil ihrer Länge in ihrer Wanddicke verringert werden, um als Liner für eine Verbundgasflasche für 300 bar Fülldruck geeignet zu sein. Dabei ist der wesentliche Teil ihrer Länge zylindrisch ausgebildet, was eine spanende Bearbeitung einfach ermöglicht. Unter spanender Bearbeitung werden im wesentlichen die Fertigungsverfahren Drehen, Hobeln, Fräsen und Schleifen verstanden. Andere Fertigungsverfahren, insbesondere Umformen durch Ziehen oder Pressen, werden durch die Erfindung nicht ausgeschlossen.The pressure gas bottle known per se, as used by the gas manufacturers to transport the gases and gas mixtures in liquid or dissolved form, only has to be reduced in wall thickness over a substantial part of its length in order to be suitable as a liner for a composite gas bottle for a filling pressure of 300 bar to be. The major part of its length is cylindrical, which is a simple machining. Machining essentially means the manufacturing processes turning, planing, milling and grinding. Other manufacturing processes, in particular forming by drawing or pressing, are not excluded by the invention.
Ein besonders einfaches Verfahren zur Herstellung des Liners besteht darin, daß die Wanddicke des zylindrischen Teils der an sich bekannten Druckgasflasche mit einem Sensor erfaßt wird und einer Steuerung eines Werkzeuges als Istwert zugeführt wird. Der vom Sensor erfaßte Istwert wird als Steuersignal verwendet. In Abhängigkeit von dem Istsignal und einem vorgegebenen Wanddicken Sollsignal wird ein spanendes Werkzeug entlang des zylindrischen Teils verfahren. Das Werkzeug trägt die Wanddicke der an sich bekannten Druckgasflasche auf dem zylindrischen Teil ab, bis der rechnerisch in Abhängigkeit von dem Druckgasflaschenwerkstoff ermittelte Sollwert erreicht ist.A particularly simple method for producing the liner consists in that the wall thickness of the cylindrical part of the pressure gas bottle known per se is detected with a sensor and is fed to a control of a tool as the actual value. The actual value detected by the sensor is used as a control signal. Depending on the actual signal and a predetermined wall thickness target signal, a cutting tool is moved along the cylindrical part. The tool removes the wall thickness of the pressure gas bottle known per se from the cylindrical part until the target value calculated as a function of the pressure gas bottle material is reached.
Der Einsatz einer an sich bekannten Druckgasflasche, die ohne Verringerung der Wanddicke als Liner eingesetzt und deren Oberfläche mittels Sandstrahlen gereinigt ist, führt vorteilhaft zu Verbundgasflaschen mit einem Fülldruck von > 300 bar, nämlich ca. 470 bar bei einer an sich bekannten 200 bar Druckgasflasche aus Stahl. Diese an sich bekannte Druckgasflasche aus Stahl hat einen Berstdruck von ca. 600 bar. Dabei ist der Berstdruck des unbewickelten Liners gleich oder größer 85% des Prüfdruckes der bewickelten Verbundflasche. Daraus folgt 600 bar/0.85 = 705 bar Prüfdruck. Der Fülldruck der Verbundflasche berechnet sich aus Prüfdruck/1.5 = ca. 470 bar.The use of a pressure gas bottle known per se, which is used as a liner without reducing the wall thickness and whose surface is cleaned by means of sandblasting, advantageously leads to composite gas bottles with a filling pressure of> 300 bar, namely approx. 470 bar with a 200 bar pressure gas bottle known per se Steel. This steel gas cylinder, known per se, has a burst pressure of approx. 600 bar. The burst pressure of the unwrapped liner is equal to or greater than 85% of the test pressure of the wrapped composite bottle. This results in 600 bar / 0.85 = 705 bar test pressure. The filling pressure of the compound bottle is calculated from the test pressure / 1.5 = approx. 470 bar.
Die an sich bekannte Druckgasflasche besteht aus den Werkstoffen Kunststoff, Stahl, Edelstahl oder Aluminium. The known compressed gas cylinder consists of the materials plastic, steel, stainless steel or aluminum.
