Die Erfindung betrifft eine Vorrichtung zum Reinigen von Wasserstoff, in welcher die Reinigung des Wasserstoffes durch Hindurchgang durch Palladiummetall, einem an sich bekannten Prinzip, erfolgt.The invention relates to a device for cleaning hydrogen, in which the cleaning of the Hydrogen occurs by passing through palladium metal, a principle known per se.
Die erfindungsgemäße Reinigungsvorrichtung ist kompakt gebaut und ergibt dennoch einen wesentlichen Ausstoß an gereinigtem Wasserstoff. Der sogenannte technische Wasserstoff besitzt im allgemeinen eine Reinheit von etwa 99,5 °/o und enthält als Verunreinigungen Gase wie Sauerstoff, Kohlenwasserstoffe und Wasserdampf. Die erfindungsgemäße Reinigungsvorrichtung entfernt diese Verunreinigungen unter Erzeugung von reinem Wasserstoff, eignet sich jedoch auch zur Reinigung eines Wasserstoffs, der einen viel höheren Prozentsatz an Verunreinigungen als der technische Wasserstoff enthält, und kann beispielsweise zur Reinigung eines Gases verwendet werden, in welchem Wasserstoff nur in einer Menge von 50 bis 60% enthalten ist. Die Vorrichtung kann bei einer Temperatur von etwa 275 bis 550° C betrieben werden, und gute Ergebnisse sind bei einer Betriebstemperatur von etwa 400° C erzielt worden. Der Druck kann im Bereich von Atmosphärendruck bis 7 atü oder darüber Hegen.The cleaning device according to the invention is compactly built and still results in a significant amount of purified hydrogen. The so-called Technical hydrogen generally has a purity of about 99.5% and contains impurities Gases such as oxygen, hydrocarbons and water vapor. The cleaning device according to the invention removes these contaminants to produce pure hydrogen, but is suitable also to purify a hydrogen that has a much higher percentage of impurities than that contains technical hydrogen and can be used, for example, to purify a gas, in which hydrogen is only contained in an amount of 50 to 60%. The device can at can be operated at a temperature of about 275 to 550 ° C, and good results are at an operating temperature of about 400 ° C has been achieved. The pressure can range from atmospheric pressure to 7 atü or cherish over it.
In der Zeichnung ist eine beispielsweise Ausführungsform der erfindungsgemäßen Reinigungsvorrichtung dargestellt. Es zeigtIn the drawing is an exemplary embodiment of the cleaning device according to the invention shown. It shows
Fig. 1 in Seitenansicht das zur Ausfüllung eines Mantelrohres bestimmte Rohrbündel mit Endplatten, aus welchem der Reinigungsteil der erfindungsgemäßen Vorrichtung aufgebaut ist,1 shows a side view of the tube bundle with end plates intended for filling a jacket tube, from which the cleaning part of the device according to the invention is constructed,
Fig. 2 die Endansicht des Rohrbündels, wobei die an der Endplatte befestigten Rohre zu erkennen sind, und2 shows the end view of the tube bundle, showing the tubes attached to the end plate, and
Fig. 3 einen Schnitt durch die zusammengebaute R einigungsvor r ichtung.Fig. 3 is a section through the assembled cleaning device direction.
Das Rohrbündel (Fig. 1 und 2) besteht aus einer großen Anzahl von Palladiumrohren 2, die an den beiden Endplatten 4 bzw. 6 befestigt sind. Die Endplatten können aus einem geeigneten Werkstoff, wie rostfreiem Stahl, bestehen; die Rohre sind an ihnen mittels Silberlot befestigt.The tube bundle (Fig. 1 and 2) consists of a large number of palladium tubes 2, which are attached to the two end plates 4 and 6, respectively. The end plates can be made of any suitable material such as stainless steel; the tubes are attached to them with silver solder.
Wie Fig. 3 zeigt, sind das Rohrbündel 2 und die Endplatten 4 und 6 in einen Mantel 8 aus rostfreiem Stahl eingesetzt, an dessen Enden durch beliebige geeignete Mittel, beispielsweise Verschweißung, die Kappen 10 bzw. 12 aus rostfreiem Stahl befestigt sind.As Fig. 3 shows, the tube bundle 2 and the end plates 4 and 6 are in a jacket 8 made of stainless Steel used at the ends by any suitable means, such as welding, the Caps 10 and 12 made of stainless steel are attached.
Die Kappe 10 weist einen Einlaß 14 auf, der zur Einführung von unreinem Wasserstoff in die Vorrichtung dient, während die Kappe 12 mit dem ein Ventil 18 aufweisenden Ablaßrohr 16 versehen ist, das zur Ableitung der Verunreinigungen aus dem Inneren des Rohrbündels 2 dient. In der Wandung des Mantels 8The cap 10 has an inlet 14 for the introduction of impure hydrogen into the device serves, while the cap 12 is provided with the drain pipe 16 having a valve 18, which for Discharge of the impurities from the interior of the tube bundle 2 is used.

ist ein Auslaß 19 vorgesehen, von welchem gereinigter Wasserstoff, der die Wandungen der Rohre 2 durchdrungen hat, aus dem Mantel abgezogen werden kann.an outlet 19 is provided, from which purified hydrogen, which the walls of the tubes 2 has penetrated, can be pulled from the coat.
Der Stahlmantel 8 ist von einer Widerstandswicklung 20 umgeben, die aus einem beliebigen geeigneten Material, wie Nickel-Chrom-Legierung besteht; diese Wicklung ist mit einer Kittschicht 22, beispielsweise aus Asbestzement, umhüllt oder in dieselbe eingebettet. The steel jacket 8 is surrounded by a resistance winding 20 made of any suitable Material such as nickel-chromium alloy is made; this winding is covered with a layer of cement 22, for example made of asbestos cement, coated or embedded in the same.
Die gesamte Vorrichtung ist in einem Aluminiumbehälter bzw. -gehäuse 24 untergebracht, das mit Endplatten 26 aus einem geeigneten Werkstoff, wie Asbestzement od. dgl. versehen ist. Die Reinigungsvorrichtung ist gegen den Behälter 24 mittels eines geeigneten Isolierstoffs 28, z. B. Magnesiumoxyd, isoliert.The entire device is housed in an aluminum container or housing 24 with end plates 26 made of a suitable material, such as asbestos cement or the like. Is provided. The cleaning device is against the container 24 by means of a suitable insulating material 28, for. B. magnesium oxide, isolated.
Bei der Herstellung der erfindungsgemäßen Reinigungsvorrichtung werden die Palladiumrohre auf einem Dorn gewickelt, der in einer am einen Ende befindlichen Kopfplatte mehrere zur Achse des Dorns konzentrisch angeordnete Kreisreihen von Löchern aufweist. Ein Ende jedes Rohres wird in einem Loch befestigt, und der Abstand der Löcher bestimmt den Neigungswinkel der Rohrwicklung. Wenn beispielsweise die erste Lage vier Rohre enthält, kann die zweite Lage, die im umgekehrten Sinn direkt auf die erste Lage aufgewickelt wird, fünf Rohre, die dritte Lage sechs Rohre und die vierte Lage sieben Rohre aufweisen.During the production of the cleaning device according to the invention, the palladium tubes are opened a mandrel wound, which in a head plate located at one end several to the axis of the mandrel having concentrically arranged rows of holes. One end of each tube goes into a hole attached, and the distance between the holes determines the angle of inclination of the pipe winding. For example, if the first layer contains four tubes, the second layer, which in the opposite sense can be directly on the first layer is wound up, five tubes, the third layer six tubes and the fourth layer seven tubes exhibit.
