 EMI1.1 
 



   Gegenstand der Erfindung ist ein Verfahren zum Trocknen von 01 ohne   jegliche Wärmezufuhr   bei dem das Öl in möglichst fein verteiltem Zustand einem Vakuum ausgesetzt wird. Unter dem Einfluss dieses Vakuums verdunstet die in dem Öl enthaltene Feuchtigkeit und wird in Form von Wasserdampf zugleich mit leicht verdunstenden   Ölteilchen   abgesaugt. Durch die innige Berührung der Ölteilchen mit der unter Unterdruck stehenden Luft wird mit Sicherheit die Entfernung aller Feuchtigkeitsteilchen bewirkt. Die früher gehegte Befürchtung, dass durch die Berührung mit Luft die Eigenschaften des Öls, z. B. die elektrischen Eigenschaften von Isolierölen, leiden, hat sich als nicht gerechtfertigt erwiesen, so dass die günstigen Ergebnisse des Verfahrens nicht durch irgend welche unerfreuliche Nebenerscheinun-

   Das Verfahren übt man zweckmässig so aus, dass man in einen Behälter, in dem (z. B. durch eine Saugpumpe) ein Vakuum erzeugt wird, das zu trocknende Öl einströmen lässt. Die Eintrittsstelle des Öls kann man nun so ausbilden, dass gleich hier das Öl fein verteilt wird, indem man viele kleine Öffnungen mit rundem oder   schlitzförmigem   Querschnitt nach Art von Düsen vorsieht, oder man lässt das Öl über geeignet geformte, im Verdampferraum befindliche Körper fliessen, bei denen man durch eine grosse Oberfläche in bekannter Weise dafür sorgt, dass das Öl in dünner Schicht über sie hinweggleitet. Das Öl sammelt sich dann am Boden an und kann von dort abgesaugt werden. In welcher Weise man die beiden

 EMI1.1
 



   The invention relates to a method for drying oil without any supply of heat, in which the oil is subjected to a vacuum in a state that is as finely divided as possible. Under the influence of this vacuum, the moisture contained in the oil evaporates and is sucked off in the form of water vapor at the same time as easily evaporating oil particles. The intimate contact of the oil particles with the air under reduced pressure is sure to remove all moisture particles. The earlier fear that the properties of the oil, e.g. B. the electrical properties of insulating oils, has not proven to be justified, so that the favorable results of the process are not affected by any unpleasant side effects.
 EMI1.2
 



   The method is expediently carried out by letting the oil to be dried flow into a container in which a vacuum is generated (e.g. by a suction pump). The entry point of the oil can now be designed in such a way that the oil is finely distributed right here by providing many small openings with round or slot-shaped cross-sections in the manner of nozzles, or the oil can flow over suitably shaped bodies located in the evaporator chamber, where a large surface ensures in a known way that the oil glides over them in a thin layer. The oil then collects on the bottom and can be sucked off from there. In what way you the two
