Description

Vorrichtung zur elektrolytischen Komprimierung von elektrolytisch getrennt entwickelten Gasen, besonders von Sauerstoff und Wasserstoff. Die vorliegende Erfindung betrifft Vorrichtungen, um Gase, besonders Sauerstoff und Wasserstoff, getrennt elektrolytisch zu gewinnen und gleichzeitig zu komprimieren, und so zur Verflüssigung im Sauerstoff- oder Wasserstoffverflüssiger nach dem Gegenstromprinzip durch adiabatische Expansion oder auch zum Füllen von Gasbehältern (z. B. Bomben) zu verwenden.Device for electrolytic compression of electrolytic separately evolved gases, especially oxygen and hydrogen. The present The invention relates to devices to gas, especially oxygen and hydrogen, to be obtained electrolytically separately and at the same time to compress, and so for Liquefaction in the oxygen or hydrogen liquefier according to the countercurrent principle through adiabatic expansion or for filling gas containers (e.g. bombs) to use.

Die Abb. i der Zeichnung erläutert die Erfindung schematisch. In den Zellen Z, entweder Glocken- (wie gezeichnet) oder Diaphragmendruckelektrolyseuren, wird Sauerstoff und Wasserstoff getrennt entwickelt und durch Rohrleitungen` den Behältern 0, oder H, (Druckflaschen) zugeführt. Da. es nun praktisch unmöglich ist, die Volumina der Sauerstoff- und Wasserstoffbehälter sowie der dazugehörigen Rohrleitungen inhaltlich genau im Verhältnis 2 : i zu bauen, war es nötig. einen Druckregler zu finden, der bei der elektrolytischen Kompression empfindlich genug die Drucke auf der Sauerstoff- und Wasserstoffseite in der Apparatur ganz gleich hält, da ein Überdruck auf der einen Seite im Elektrolyseur den Elektrolyten nach der anderen Seite herausdrücken würde.Fig. I of the drawing explains the invention schematically. In cells Z, either bell (as shown) or diaphragm pressure electrolysers, oxygen and hydrogen are developed separately and fed through pipes to containers 0 or H (pressure bottles). There. it is now practically impossible to build the volumes of the oxygen and hydrogen tanks as well as the associated pipelines in an exact ratio of 2: i, it was necessary. To find a pressure regulator that is sensitive enough to keep the pressure on the oxygen and hydrogen side in the apparatus exactly the same during electrolytic compression, since an overpressure on one side in the electrolyzer would push the electrolyte out to the other.

Der Druckregler besteht aus einem an die beiden Gasleitungen angeschlossenen Differentialmanometer D, das beispielsweise mit Quecksilber gefüllt ist. Steigt nun z. B. der Druck auf der Sauerstoffseite, so steigt das Quecksilber nach der Zeichnung im rechten Schenkel des Manometers, dadurch wird vermittels des Kontaktstiftes k ein elektrischer Strom geschlossen, der den Magneten m des an die Sauerstoffleitung angeschlossenen Ventils v erregt und durch Anziehen von a das Ventil öffnet, so daß Sauerstoff ausströmt und der Druck auf dieser Seite sinkt. Ist der Druck auf der Wasserstoffseite höher, so steigt das Quecksilber im linken Schenkel des Manometers und bewirkt hier durch Berühren des Kontaktstiftes k den Stromkreisschluß, der das Wasserstoffventil öffnet; i sind isolierte Stromdurchführungen. Die Ventile können so konstruiert werden, daß die ausströmenden Gase gefaßt und mit oder ohne Gegendruck Gasometern zugeführt werden können. Zur Füllung des Manometers können zur Erhöhung der Empfindlichkeit anstatt Quecksilber auch spezifisch leichtere Flüssigkeiten (Salzlösungen, Laugen, Säuren) benutzt werden, die allerdings nur schwächere Ströme durchlassen, durch Einschaltung von Relais aber doch die Ventile elektrisch steuern könnten. Wird die Apparatur durch Anschließen an Sauerstoff- und Wasserstoffverflüssiger zur Verflüssigung der Gase (ohne jeden mechanischen Kompressor) verwendet, so können die Ventile v in den Verflüssiger eingebaut werden, um auch die an ihnen auftretende Expansionsabkühlung auszunutzen.The pressure regulator consists of one connected to the two gas lines Differential manometer D, which is filled with mercury, for example. Increases now z. B. the pressure on the oxygen side, the mercury rises after the Drawing in the right leg of the manometer, through which the contact pin is used k an electric current closed, which the magnet m des to the oxygen line connected valve v is excited and the valve opens by tightening a, so that oxygen flows out and the pressure on this side drops. Is the pressure on higher on the hydrogen side, the mercury rises in the left arm of the manometer and here, by touching the contact pin k, causes the circuit to shorten the circuit Hydrogen valve opens; i are isolated power feedthroughs. The valves can be constructed in such a way that the outflowing gases are contained and with or without counter pressure Gasometers can be fed. To fill the pressure gauge you can increase the sensitivity instead of mercury also specifically lighter liquids (Salt solutions, alkalis, acids) are used, but these only have weaker currents let through, but still control the valves electrically by switching on relays could. The apparatus is made by connecting it to oxygen and hydrogen liquefiers used to liquefy the gases (without any mechanical compressor), so can the valves v are built into the condenser in order to also prevent the occurring on them Exploit expansion cooling.

Durch Abb. 2 wird das näher erläutert. Die in der Hauptzeichnung mit »Verflüssiger« gekennzeichnete Leitung für komprimierten Sauerstoff und Wasserstoff schließt sich in normaler `'eise bei x an einen Gegenstromverflüssiger an. Das Gas durchströmt denselben und steht bis zum Nadelventil y unter dem Zellendruck.This is explained in more detail in Fig. 2. The one in the main drawing with "Liquefier" marked line for compressed oxygen and hydrogen normally connects to a countercurrent condenser at x. The gas flows through the same and is under the cell pressure up to the needle valve y.

Die zur Gleichhaltung des Druckes auf beiden Gasseiten der elektrolytischen Zelle in Abb. i mit v H., und" v 0" bezeichneten elektrischen Ventile sind nach Äbb. 2 zur Ausnutzung der auch an ihnen auftretenden Expansionsabkühlung in den Verflüssiger gelegt; sie schließen sich kurz vor dem Nadelventil y bei r an die innere Druckleitung des Gegenstromapparates im Verflüssiger an und, wenn sie durch den Druckregler betätigt werden, öffnen sie sich und bewirken eine weitere Entspannung der Druckleitung und so des Überdrucks auf der einen Seite der Zelle. Das so entspannte Gas geht mit dem durch das Nadelventil y entspannten Gas gemeinsam in den Gegenstromapparat und trägt zur Vorkühlung des Druckgases bei.To keep the pressure equal on both gas sides of the electrolytic cell in Fig. 2 placed in the condenser to take advantage of the expansion cooling that also occurs on them; they connect to the internal pressure line of the counterflow device in the condenser shortly before the needle valve y at r and, if they are actuated by the pressure regulator, they open and cause a further expansion of the pressure line and thus the overpressure on one side of the cell. The gas thus expanded goes together with the gas expanded through the needle valve y into the counterflow apparatus and contributes to the precooling of the compressed gas.
