Terfahren zum Behandeln von Stoffgemischen.Terfahren for the treatment of mixtures of substances.
Vorliegende Erfindung betrifft Verfahren zum Behandeln von Stoffgemischen, vorzugsweise vor nachfolgender Durchführung von der Abtrennung, etwa Abfilterung eines einzelnen Mischungsbestandteiles oder mehrerer derselben dienenden Trennungs- insbesondere Filtrierverfahren.The present invention relates to methods of treating of mixtures of substances, preferably before the subsequent implementation from the separation, such as filtering off a single component of the mixture or several of the same Serving separation processes, in particular filtering processes.
Das erfindungsgemäss vorgeschlagene Verfallen kennzeichnet sich dadurch, dass da,s Gemisch an wenigstens einem der Mischungsbestandteile,vorzugsweise an dem nachfolgend abzutrennenden Mischungsbestandteil oder an mehreren derselben, durch Zuführung desselben oder derselben zur Mischung angereichert wird.The expiration proposed according to the invention characterizes by the fact that there is a mixture of at least one of the mixture components, preferably the subsequently to be separated mixture component or at several of the same, by supplying the same or the same is enriched to the mixture.
Das Verfahren kann mit besonderem Vorteil bei Stoffgemischen mit wenigsten einer flüssigen Phase zur Anwendung kommen. Eine weitere, wichtige Anwendung kennzeichnet sich dadurch, dass dem Verfahren Stoffgemische mit zwei flüssigen Phasen, etwa in Form von Emulsionen oder Suspensionen, unterworfen werden. Vorteilheft ist weiter die Anwendung des Verfahrens bei abzusch-eidende Öle enthaltenden Emulsionen oder Suspensionen, wobei vor allem öl in V/asser - Emulsionen oder Suspensionen in Betracht kommen.The method can be used with particular advantage in mixtures of substances with at least one liquid phase come. Another important application is that the process uses mixtures of substances with two liquid phases, for example in the form of emulsions or suspensions. Advantage book is furthermore, the application of the method to emulsions or suspensions containing oils to be deposited, whereby before all oil in water emulsions or suspensions in Come into consideration.

Eine weitere, vorteilhafte Ausbildung des Verfahrens kennzeichnet sich dadurch, dass während oder nach der Anreicherung die Mischung verfeinert wird. Das kann beispielsweise in üblicher Weise durch Schütteln, Vibrieren, Schnellrühren, Anwendung von Ultraschall oder mittels anderer, bekannter Maßnahmen erfolgen*Another advantageous embodiment of the method is characterized by the fact that the mixture is refined during or after the enrichment. For example in the usual way by shaking, vibrating, rapid stirring, using ultrasound or by means of other, known measures take place *
Weiter können die Agglomeration fördernde Mittel zur Anwendung kommen. Beispielsweise hat sich gezeigt, dass die Zuführung in den Mischungsbestandteilen nicht löslicher, disperser Stoffe wie lisenfeilicht, Kohlekörner oder dergleichen zweckmässig ist. In Betracht kommt auch die Zuführung oberflächenreicher Körper wie aktiver Kohle. Die Agglomeration wird weiter begünstigt durch Einführung oberflächenaktiver Stoffe, unter denen Metallhydroxide besonders geeignet sind, wobei sich Eisenhydroxide wegen ihrer besonderen Wirksamkeit und durch geringe Gestehungskosten auszeichnen. Anwendbar sind aber auch beispielsweise Aluminium- und andere, in den Mischbestandteilen unlösbare Metallhydroxide. Als die Mischung verfein-ernde Mittel kommen beispielsweise Eisen- oder Stahlspäne "in Betracht, durch die die Mischung, etwa unter Anwendung von Pumpen, Strahlrohren, Düsen oder dergleichen, durchgetrieben wird. Anwesende Metallhydroxide zeigen bei der Agglomeration eine gewisse katalytisehe Wirkungj lediglich durch Anwesenheit der Hydroxide erfolgt eine verstärkte Zusammenballung des abzuscheidenden Öles,oder sonstiger, abzuscheidender Mischungsbestandteile, so dass es sich gerade bei Öl in Wasser - Emulsionen als zweckmässig erwiesen hat, der Mischung noch vor der Mltrierung Eisenhydroxide in disperser lorm zuzusetzen. Dadurch agglomerieren die öltröpfchen verstärkt und bilden grössere Ölansammlungen. So Jhat es sich gezeigt, dass milchig aussehende Ölwasser-Emulsionen sich aufhellen und sogar durch Anwendung mehrererAgglomeration-promoting agents can also be used Application. For example, it has been shown that the addition of more insoluble in the mixture components, disperse substances such as lisenfeilicht, grains of coal or the like is appropriate. Feeding is also an option surface-rich bodies such as active charcoal. The agglomeration is further promoted by the introduction of surface-active substances Substances, among which metal hydroxides are particularly suitable, with iron hydroxides because of their particularly effective and characterized by low production costs. However, aluminum and other metal hydroxides which are insoluble in the mixed components can also be used. As the mixture comes refining agents for example iron or steel filings "into consideration by the the mixture is driven through, for example using pumps, jet pipes, nozzles or the like. Metal hydroxides present show a certain catalytic effect on agglomeration Effect only takes place through the presence of the hydroxides an increased agglomeration of the oil to be separated, or other, to be separated mixture components, so that it proved to be useful especially with oil in water emulsions has iron hydroxide in the mixture before it is melted to be added in disperse lorm. This causes the oil droplets to agglomerate strengthen and form larger oil accumulations. So Jhat it has been shown to be milky-looking oil water emulsions lighten themselves and even by applying more than one

der oben vorgeschlagenen Maßnahmen völlig klären lassen. Filtriert man dr-nn anschliessend die Öl-Wasser-Emulsion durch eine dünne Schicht aus Eisenhydroxid, so erhält man als Filtrat Wasser, das auch nach der Abfiltrierung von Spaltölen, die sich durch einen besonders intensiven Geruch auszeichnen, infolge auftretender Geruchlosigkeit trinkbrr ist.completely clarify the measures suggested above permit. The oil-water emulsion is then filtered dr-nn through a thin layer of iron hydroxide, water is obtained as the filtrate, and that too after filtering off fission oils that spread through have a particularly intense odor, is drinkable due to the lack of odor.
