Description

Verfahren zur Bereitung von Preßgasen verschiedenen regelbaren Druckes aus ihrem flüssigen Aggregatzustande Die Erfindung bezieht sich auf ein Verfahren zur Erzeugung von Hochdruckgasen mit einem den kritischen Druck (etwa 52 at) übersteigenden Drucke. Durch das neue Verfahren soll erreicht werden, daß bei der Entnahme des Hochdruckgases der Druck des im Druckbehälter befindlichen, vollständig in Gasform übergegangenen Sauerstoffes o. dgl. annähernd konstant gehalten wird. Das wird dadurch erreicht, daß das aus dem Behälter entnommene Gas in einer äußeren Rohrschlange erwärmt und in erwärmtem Zustande durch eine weitere Rohrschlange geführt wird, die zur Beheizung des im Druckbehälter befindlichen Kaltgases dient.Process for the preparation of compressed gases of various controllable pressures from their liquid state of aggregation The invention relates to a method for the generation of high-pressure gases with a pressure exceeding the critical pressure (approx. 52 at) Prints. The aim of the new method is to ensure that when the High pressure gas is the pressure of the pressure in the pressure vessel, completely in gaseous form transferred oxygen or the like. Is kept approximately constant. That will be the result achieves that the gas withdrawn from the container in an outer coil is heated and, in a heated state, is passed through another pipe coil, which is used to heat the cold gas in the pressure vessel.

Es ist bereits ein Verfahren zur Erzeugung von Preßgas von einem verhältnismäßig niedrigen Drucke bekannt, bei welchem das aus dem Flüssigkeitsbehälter entwickelte Gas ebenso wie beim Gegenstande der Erfindung in einer äußeren Rohrschlange erwärmt und sodann zur Beheizung des Behälters benutzt wird. Hier handelt es sich, wie gesagt, nur um niedrige Gasdrücke. Durch ein Sicherheitsventil wird dafür gesorgt, daß diese niedrigen Gasdrücke im Innern des Behälters nicht überschritten werden. Ein den kritischen Druck überschreitender Druck kann also im Behälter überhaupt nicht entstehen. Das Gas im Behälter befindet sich infolgedessen in flüssigem Zustande, und die durch die Rohrschlange zugeführte Wärme dient lediglich zur Verdampfung der Flüssigkeit. Das neue Verfahren will hohe Drücke benutzen, bei denen sich der Sauerstoff nicht mehr in flüssigem Zustande befindet, sondern ganz in Gasform übergegangen ist. Hierbei dient die zugeführte Beheizungswärme nicht mehr zur Verdampfung der Flüssigkeit, sondern zur Überhitzung des im Behälter befindlichen Kaltgases. Dadurch wird erreicht, daß der Druck des Gases trotz der Entnahme annähernd konstant bleibt. Der Erfindung liegt die Erkenntnis zugrunde, daß es bei Verwendung des an sich bekannten Beheizungsverfahrens möglich ist, den Druck im Innern des Behälters auch dann konstant zu erhalten, wenn hohe Drücke zur Verwendung kommen und sich im Behälter nur Gas allein befindet. Diese Erkenntnis ist dem bekannten Verfahren nicht zu entnehmen.It is already a method of generating compressed gas from a relative known low pressures at which the evolved from the liquid container Gas heated in the same way as in the subject matter of the invention in an outer coil and then used to heat the container. As I said, this is just about low gas pressures. A safety valve ensures that this low gas pressures inside the container are not exceeded. A den Pressure exceeding critical pressure cannot develop in the container at all. As a result, the gas in the container is in a liquid state, and the through the heat supplied to the coil serves only to evaporate the liquid. The new method wants to use high pressures at which the oxygen cannot is more in the liquid state, but has passed completely into gaseous form. Here the supplied heating heat is no longer used to evaporate the liquid, but rather to overheat the cold gas in the container. This achieves that the pressure of the gas remains approximately constant despite the withdrawal. The invention is based on the knowledge that when using the heating process known per se it is possible to keep the pressure inside the container constant even if high pressures are used and there is only gas in the container. This finding cannot be inferred from the known method.

Nach Abb. i wird das Druckgas im Behälter i, nachdem es das geöffnete Ventil 3 und die Schlange 5, 6 passiert hat, nach seiner Erwärmung in der Atmosphäre bei geschlossenem Ventil ii und geöffnetem Ventil a in eine mit dem Behälter i in engen Metallkontakt gebrachte Kupferschlange b geleitet, so daß die Erwärmung und Durchheizung des Druckgefäßes i mit Hilfe der durch die Rohrschlange b strömenden Gasmenge geschieht. Das abgekühlte Gas strömt dann durch d wieder in die Hauptleitung e ein und kann nun entweder unmittelbar dem Verbrauchsort zugeführt oder vorher noch in der Schlange f erwärmt werden.According to Fig. I, the pressurized gas in the container i after it has opened Valve 3 and the coil 5, 6 has passed after it has been heated in the atmosphere with valve ii closed and valve a open in one with the container i in close metal contact brought copper snake b passed so that the heating and Through heating of the pressure vessel i with the aid of the flowing through the coil b Amount of gas happens. The cooled down Gas then flows through d again into the main line e and can now either be fed directly to the place of consumption or be warmed up beforehand in the queue f.

Abb.2 zeigt eine andere Anordnung der Heizschlange b. Sie ist in den dünnwandigen Einsatz g hineinverlegt, um so direkt den Gasinhalt anzuwärmen.Fig.2 shows another arrangement of the heating coil b. She is in the thin-walled insert g moved into it in order to heat the gas content directly.

Soll die Beheizungseinrichtung außer Betrieb gesetzt werden, so ist es nur erforderlich, das Ventil a zu schließen und das Ventil ii wieder zu öffnen.If the heating device is to be put out of operation, then it is only necessary to close the valve a and to open the valve ii again.

Es soll nicht unerwähnt bleiben, daß in solchen Fällen, wo die Rückleitung der erwärmten Gase zur Abgabe von Wärme nicht hinreichen sollte, durch dafür vorgesehene Heizleitungen auch Heizmittel aus fremden Quellen (atmosphärische Luft, warmes Wasser u. dgl.) hindurchgeschickt werden können.It should not go unmentioned that in such cases where the return line the heated gases should not be sufficient to give off heat, by means of those provided Heating cables also use heating media from external sources (atmospheric air, warm water and the like) can be sent through.
