Abstract
Description
Die Erfindung betrifft ein Verfahren zum Befüllen einer Druckgasflasche mit Ethen nach dem Oberbegriff des Anspruchs 1.The invention relates to a method for filling a compressed gas bottle with ethene according to the preamble of claim 1.
Bei den Verfahren der Autogentechnik (zum Beispiel Brennschneider, Löten, Schweißen) hängt die Qualität und Wirtschaftlichkeit des Arbeitsergebnisses auch mit der Auswahl des Brenngases zusammen. Eine hohe spezifische Leistung ist an die Lieferung der Bildungswärme pro Masseneinheit gekoppelt. Diese Bildungswärme wird vor dem eigentlichen Verbrennungsprozeß beim Aufspalten der Brenngasmoleküle in seine atomaren Bestandteile frei. Beim autogenen Schweißen oder Schneiden verwendet man daher als Brenngas nahezu ausschließlich Acetylen, da mit ihm die höchste Bildungswärme erzielt wird.In the processes of oxyfuel technology (e.g. flame cutters, soldering, welding), the quality and economy of the work result also depend on the selection of the fuel gas. A high specific output is linked to the supply of heat of formation per unit of mass. This heat of formation is released before the actual combustion process when the fuel gas molecules are split into its atomic components. In oxyacetylene welding or cutting, acetylene is therefore almost exclusively used as the fuel gas, since it achieves the highest heat of formation.
Neben diesen vom thermischen Bearbeitungsverfahren bestimmten Wirtschaftlichkeitsbetrachtungen, stellen auch die Brenngas- Versorgungssysteme einen Wirtschaftlichkeitsfaktor dar, der bei einer Gesamtbetrachtung zu berücksichtigen ist. Neben der Forderung nach ökonomischer Bevorratung ist auch den entsprechenden Sicherheitsstandards zu genügen. Bei Acetylen ist eine poröse Masse zur sicheren Zerfallsverhinderung erforderlich. Diese legt die Acteylen-Versorgung auf das Speichermittel Druckgasflasche fest.In addition to these economic considerations determined by the thermal processing method, the fuel gas supply systems also represent an economic factor that must be taken into account in an overall view. In addition to the requirement for economic storage, the corresponding security standards must also be met. In the case of acetylene, a porous mass is required to prevent it from decaying. This specifies the supply of acetylene to the compressed gas cylinder storage medium.
Acetylen-Versorgungssysteme basieren, je nach Bedarf, auf Einzelflaschen, Flaschenbaterien und Bündel. Mit einem Lösungsmittel zur Aufnahme des Acetylens wird die Beladung der Acetylenflasche wesentlich gesteigert.Depending on requirements, acetylene supply systems are based on individual cylinders, cylinder batteries and bundles. With a solvent to absorb the acetylene, the loading of the acetylene bottle is significantly increased.
Ethen entspricht in seiner logistischen Anwendung aufgrund seiner recht ähnlichen physikalischen Daten stark dem Erdgas. Brenngasphysikalisch entspricht es jedoch weitgehend dem Acetylen. Die gegenüber dem Acetylen graduell, geringere Bildungswärme verhindert allerdings unter Druck oder Verflüssigung ein Zerfall des Brenngases. Es kann daher sowohl in der Druckgasflasche als auch tiefkalt-flüssig gespeichert werden.In its logistical application, Ethen is very similar to natural gas due to its very similar physical data. In terms of fuel gas, however, it largely corresponds to acetylene. The gradual lower heat of formation compared to acetylene prevents the combustion gas from decomposing under pressure or liquefaction. It can therefore be stored in the compressed gas bottle as well as in cryogenic liquid.
Nachteilig bei den Druckgasflaschen, in denen Ethen bei einem Druck von beispielsweise 135 bar gespeichert ist, ist die Schwierigkeit bei der Entnahme aufgrund von Vereisungseffekten am Druckminderer. Dies macht Verdampfereinrichtungen erforderlich, die in der Praxis für zum Beispiel bewegliche Arbeitseitsplätze inakzeptabel sind.A disadvantage of the compressed gas cylinders, in which ethene is stored at a pressure of, for example, 135 bar, is the difficulty in the removal due to icing effects on the pressure reducer. This necessitates evaporator devices which are unacceptable in practice for, for example, mobile workplaces.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Ethen-Brenngasversorgung zum autogenen Schweißen oder Schneiden in Flaschen zu schaffen, welches bei Verfahren der Autogentechnik zu guten Ergebnissen führt und bei dem die Befüllung gegenüber Acetylen vereinfacht ist und das nicht die Entnahmeprobleme konventioneller Ethen-Druckgasflaschen hat.The invention is therefore based on the object of providing an ethene fuel gas supply for autogenous welding or cutting in bottles, which leads to good results in processes in autogenous technology and in which the filling is simplified compared to acetylene and which does not have the removal problems of conventional ethene compressed gas cylinders .
Ausgehend von dem im Oberbegriff des Anspruchs 1 berücksichtigten Stand der Technik ist diese Aufgabe erfindungsgemäß gelöst mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmalen.Starting from the prior art taken into account in the preamble of claim 1, this object is achieved according to the invention with the features specified in the characterizing part of claim 1.
Vorteilhafte Weiterbildung der Erfindung sind in den Unteransprüchen angegeben.Advantageous developments of the invention are specified in the subclaims.
Überraschend hat sich gezeigt, daß durch das erfindungsgemäße Befüllen einer eine poröse Masse enthaltenen Druckgasflasche, vorzugsweise einer Acetylenflasche, die wahlweise zusätzlich ein Lösungsmittel, vorzugsweise ein Acetylenlösungsmittel enthält, mit Ethen, sich eine sehr schnelle Befüllung, auch bei hohen Außentemperaturen, gegenüber einer Acetylenbefüllung erreichen läßt. Als poröse Massen, die durch ihre Poren und Äderchen viele kleine Kammern zu bilden vermögen, deren Abmessungen unter 2mm liegen, werden Schüttmassen oder monolithische Massen eingesetzt. Eine Schüttmasse ist beispielsweise Kieselgur, die in die Druckgasflasche eingestampft wird, ohne daß eine feste Bindung zwischen den einzelnen Materialteilchen vorliegt. Dagegen bestehen monolitische Massen, beispielsweise aus Calciumsilikaten, aus einem kompakten, den Flascheninnenraum ausfüllenden starren Körper.Surprisingly, it has been found that by filling a compressed gas bottle, preferably an acetylene bottle, which optionally contains a solvent, preferably an acetylene solvent, with ethene by filling a porous mass according to the invention, very quick filling, even at high outside temperatures, is achieved compared to filling with acetylene leaves. Bulky masses or monolithic masses are used as porous masses, which are able to form many small chambers due to their pores and veins, the dimensions of which are less than 2 mm. A bulk material is, for example, diatomaceous earth, which is pressed into the compressed gas bottle without a firm bond between the individual material particles. In contrast, monolithic masses, such as calcium silicates, consist of a compact, rigid body that fills the interior of the bottle.
Beim Befüllen einer Acetylenflasche können Acetylen-Restmengen von einer früheren Benutzung in der Flasche vorteilhaft verbleiben. Im Bezug zu dem Brenngas Acetylen können Acetylenentwickler entfallen.When filling an acetylene bottle, residual amounts of acetylene from previous use can advantageously remain in the bottle. In relation to the fuel gas acetylene, acetylene developers can be omitted.
Im Vergleich zu Ethen-Druckgasflaschen ohne poröse Masse kommt als Vorteil zum Tragen, daß das Gas ohne Einsatz eines Verdampfers problemlos entnommen werden kann.Compared to ethylene gas cylinders without a porous mass, the advantage is that the gas can be removed without the use of an evaporator.
