Description

Vorrichtung zur Verdampfung von flüssigem Sauerstoff in Transportgefäßen. Die vorliegende Erfindung bezieht sich im wesentlichen darauf, daß die Beheizung des in einem Gefäße befindlichen verflüssigten Gases nahe dem Boden des Gefäßes durch Widerstandserhitzung bewirkt wird, während jener Teil des elektrischen Heizkörpers, der durch die -oberen Flüssigkeitsschichten und durch den Gefäßdeckel zu einer außerhalb des Gefäßes angeordneten und durch Druckschwankungen betätigten Kontaktvorrichtung führt, entweder durch Wärmeisolation oder durch Querschnittsvergrößerung an der Heizwirkung nicht beteiligt ist.Device for the evaporation of liquid oxygen in transport vessels. The present invention relates essentially to the heating of the liquefied gas in a vessel near the bottom of the vessel caused by resistance heating, while that part of the electric heater that through the upper liquid layers and through the vessel lid to an outside the vessel arranged and actuated by pressure fluctuations contact device leads, either by thermal insulation or by enlarging the cross section of the heating effect is not involved.

Als Heizkörper können für den vorliegenden Zweck einfach Drähte aus Aluminium verwendet werden, da das metallische Aluminium von einer Tonerdeschutzhaut umgeben ist, die als Isolierung wirkt, während an dem als Heizfläche wirkenden unteren Teil. von kleinerem Ausschnitt die eintretende Widerstandserhitzung den Tonerdeüberzug genügend erwärmt.Wires can be used as a radiator for the present purpose Aluminum can be used because the metallic aluminum is covered by an alumina skin is surrounded, which acts as insulation, while acting as a heating surface on the lower Part. from a smaller section, the resistance heating that occurs, the alumina coating warmed up enough.

Die Ein- und Ausschaltung des elektrischen Stromes wird durch Druckveränderungen. des gasförmig gewordenen Sauerstoffs bewirkt, wobei der Gasinhalt der gesamten Rohrleitung, für deren Versorgung das Flüssig-Sauerstoff-Gefäß dienen soll, mit dem Gasraume desselben einen einzigen Druckraum bildet, dessen Druckhöhe durch den Verbrauch an den einzelnen Entnahmestellen beeinflußt wird.The switching on and off of the electric current is caused by pressure changes. of the oxygen that has become gaseous, whereby the gas content of the entire pipeline, for the supply of which the liquid-oxygen vessel is to serve, with the gas space the same forms a single pressure chamber, the pressure level of which is due to consumption is influenced at the individual tapping points.

Die Zeichnung. zeigt ein Ausführungsbeispiel der Erfindung. i ist das innere, 2 das äußere der beiden Gefäße und 3 der Vakuumraum zwischen denselben. Die beiden Gefäße sind 'durch den Holzsteg ¢ miteinander schlecht wärmeleitend zu einem einzigen Flüssig-Sauerstoff-Transportgefäße verbunden. 5 ist der Raum für die Aufnahme des Absorptionsmittels.The drawing. shows an embodiment of the invention. i is the inner, 2 the outer of the two vessels and 3 the vacuum space between them. The two vessels are 'poorly heat-conducting to one another due to the wooden bridge ¢ connected to a single liquid oxygen transport vessel. 5 is the space for the absorption of the absorbent.

6 ist ein mit der Verbrauchsleitung fest verbundener Gefäßdeckel mit :dem in die Flüssigkeit tauchenden Heizorgane und dem Austrittsrohre 8 für den in gasfönnigen Zustand übergeführten Sauerstoff. Das Heizorgan besteht aus einem Anoden- und einem Kathodendrahte 7- und 7b und dem dünneren Verbindungssteg 7c. Das Rohr 8 führt zu einem als Kälteausgleicher dienenden Gefäße 9, in dem dem gasförmig gewordenen Sauerstoff die ihm noch anhaftende Kälte entzogen wird und von wo er durch .das Rohr i o der Verbrauchsleitung zugeführt wird. An das Gefäß 9 ist die Membrankammer i i angeschlossen, . deren Membran 12 durch die Gewichtsbelastung 13 auf den nötigen Druck eingestellt werden kann. Der durch Druckschwankungen bei der Entnahme von Sauerstoff bewirkte Hoch- und Niedergang der Membran 12 schaltet den Beheizungss,trom selbsttätig ein oder aus.6 is a vessel cover which is firmly connected to the consumption line and has: the heating elements immersed in the liquid and the outlet pipe 8 for the oxygen converted into a gaseous state. The heating element consists of an anode and a cathode wire 7- and 7b and the thinner connecting web 7c. The pipe 8 leads to a vessel 9 serving as a cold equalizer, in which the cold still adhering to it is withdrawn from the oxygen that has become gaseous and from where it is fed through .das pipe io to the consumption line. The membrane chamber ii is connected to the vessel 9,. whose membrane 12 can be adjusted to the necessary pressure by the weight load 13. The rise and fall of the membrane 12 caused by pressure fluctuations when oxygen is withdrawn switches the heating system on or off automatically.

1q. ist ein IJberzug aus, Gummi, Celluloid o. dgl. schlechten Wärmeleitern, welcher kälteisolierend wirkt.1q. is a cover made of rubber, celluloid or similar bad heat conductors, which has a cold insulating effect.
