Zusatz zum Patent 444913.Addendum to patent 444913. Das in der Hauptpatentschrift 4449in beschriebene Verfahren erstreckt sich auf Gasströme, welche durch - den Verdunstungsraum hindurchgeführt werden. Bei Anwendung einer Kondensation der Lösemittel innerhalb des Verdunstungsraumes bleibt dieselbe Gasmenge immer in demselben Raum, während die Lösemittel an einer Stelle dieses Raumes verdunsten, an einer anderen kondensiert werden. The method described in the main patent specification 4449in extends relate to gas flows which are passed through the evaporation space. When using a condensation of the solvents within the evaporation space the same amount of gas always remains in the same room, while the solvents in one Evaporate in this space, be condensed in another. Besonders bei Inbetriebnahme oder Außerbetriebsetzung muß bei Vorhandensein von Luft in dem Verdunstungsraum das Lösemittelluftgemisch die minimale und gegebenenfalls die maximale Explosionsgrenze durchlaufen. Ferner würde bei Verwendung inerter Gase in dem Verdunstungsraum die Gefahr bestehen, daß durch Diffusion an undichten Stellen allmählich ein Sauerstoffzutritt aus der Luft erfolgt. Particularly when commissioning or decommissioning, it must be present of air in the evaporation space, the solvent-air mixture is the minimum and possibly pass the maximum explosion limit. Furthermore, when using inert gases in the evaporation space there is a risk of diffusion at leaks there is a gradual influx of oxygen from the air. Die Erfindung ermöglicht die einfache Herstellung eines inerten Gases für den Verdunstungsraum und die Fernhaltung von neu hinzutretendem Luftsauerstoff dadurch, daß sie in einem sekundären Kreislauf periodisch oder ständig Gas aus dem Verdunstungsraum führt und dieses in diesem sekundären Kreislauf nach dem Patent 444 9I3 einen Wäscher oder Filter bzw. eine Anordnung beider hintereinander, welche etwa vorhandenen Sauerstoff ganz oder teilweise beseitigen, passieren läßt. The invention enables the simple production of an inert gas for the evaporation room and the keeping away of newly entering atmospheric oxygen in that they periodically or continuously gas in a secondary circuit from the Evaporation space leads and this in this secondary cycle according to the patent 444 9I3 a washer or filter or an arrangement of both in a row, which remove any oxygen present in whole or in part, can pass. P A T E N T A N S P R U C H : Verfahren zur Wiedergewinnung flüchtiger Lösemittel durch Kondensation unter Verwendurig eines inerten Gases in dem Kondensationsraum, dadurch gekennzeichnet, daß man in einen sekundären Kreislauf Gas aus dem Verdunstungsraum führt und Wäscher oder Filter bzw. eine Anordnung beider hintereinander zum Binden von Luftsauerstoff nach Patent 444 913 passieren läßt. P A T E N T A N S P R U C H: Method of recovering volatile Solvent by condensation using an inert gas in the condensation space, characterized in that gas from the evaporation chamber is fed into a secondary circuit leads and scrubber or filter or an arrangement of both one behind the other for binding allows atmospheric oxygen to pass according to patent 444,913.
