Description

Verfahren zur Gewinnung des Wollfetts aus dem im bekannter Weise aus dem Abwasser von Wollwäschereien erhaltenen Schlamm Gegenstand vorliegender Erfindung bildet ein Verfahren zur Gewinnung des Wollfetts, das in den durch verschiedene Konzentrierungsverfahren für Abwässer aus Wollwäschereien entstandenen schlammigen Konzentraten enthalten ist.Process for obtaining the wool fat from the in a known manner the sludge obtained from the wastewater from wool laundries is the subject of the present invention forms a process for the extraction of the wool fat, which is in the various Concentration process for sludge wastewater resulting from wool laundries Concentrates is included.

Zur Gewinnung des in diesem verschiedenen Konzentratsorten enthaltenen Fettes ist eine gewisse Anzahl physikalischer, chemischer und thermischer Verfahren vorgeschlagen worden. Unter den physikalischen Verfahren befinden sich die Schleudermaschinen, die durch Fliehkraft die Fetteilchen niederschlagen und zusammenkleben sowie außerdem die Kalt- und Warmf lterpr essen. Diese Verfahren besitzen den großen Nachteil, daß sie sehr innige physikalische Verbindungen von Fett und Verunreinigungen bilden, wodurch die Läuterung verwickelt wird. Als chemische Verfahren sind solche bekannt, die darin bestehen, daß das Konzentrat mit Hilfe eines geeigneten Reaktionsmittels öfters bei erhöhter Temperatur behandelt wird, wobei. jedoch keine reinen Fette erhalten werden. Außerdem sind diese Verfahren sehr kostspielig, weil sie mehrere aufeinanderfolgende Arbeitsgänge zur Wiedergewinnung der angewandten Reaktionsmittel erforderlich machen. Als thermisches Verfahren ist es bekannt, das Konzertrat in offenen Behältern bei erhöhter Temperatur zu behandeln. Auch derartige Verfahren sind nachteilig, weil sich in der Wärme leicht Emulsionen bilden, die späterhin schwierig zu trennen sind.To obtain the various types of concentrate contained in this Fats are a number of physical, chemical and thermal processes has been proposed. Among the physical processes are the centrifugal machines, which knock down the fat particles through centrifugal force and stick together, as well as Eat the cold and hot filters. These processes have the major disadvantage that they form very intimate physical bonds of fat and impurities, whereby the purification becomes involved. The chemical processes known are those which consist in that the concentrate with the help of a suitable reactant is often treated at elevated temperature, with. but not pure fats can be obtained. In addition, these procedures are very costly because they are multiple successive operations to recover the reactants used make necessary. As a thermal process, it is known to use the concert council in to treat open containers at elevated temperature. Such procedures too are disadvantageous because emulsions are easily formed in the heat, which later are difficult to separate.

Es ist auch bereits bekannt, die schäumigen Konzentrate durch eine Druckbehandlung im Autoklav zu zerlegen, wobei die Konzentrate mit Wasser auf Druck von mehreren Atmosphären erhitzt werden.It is also already known that the foamy concentrates by a Pressure treatment in the autoclave to disassemble the concentrates with water on pressure be heated by several atmospheres.

Es wurde nun gefunden, daß diese Druckbehandlung bei einer wesentlich niedrigeren nur go bis ioo° betragenden Temperatur durchgeführt werden kann, wenn der zur Zerlegung nötige Druck durch Einführung eines indifferenten Gases erzeugt wird.It has now been found that this pressure treatment is essential to one lower only go to ioo ° amounting temperature can be done if the pressure required for decomposition is generated by introducing an inert gas will.

.Das vorliegende Verfahren hat zunächst den Vorteil der Wirtschaftlichkeit. . Zur Behandlung eines Konzentrates, das einen Druck von 3 bis 4 kg im Innern des Autoklavs, also bisher etwas mehr als 4 kg Druck des Heizdampfes erforderte, genügt es jetzt, das Konzentrat auf go bis ioo° C zu heizen, also unter einem Heizdampfdruck von i kg und den fehlenden Druck durch Einführung eines geringen Volumens Luft zu ersetzen. Hieraus erwächst eine Wärmeersparnis von 40 °/o.The present process initially has the advantage of economic efficiency. . For treating a concentrate that has a pressure of 3 to 4 kg inside the An autoclave, which previously required slightly more than 4 kg of heating steam pressure, is sufficient Now it is time to heat the concentrate to 100 ° C, i.e. under a heating steam pressure of i kg and the lack of pressure by introducing a small volume of air substitute. This results in a heat saving of 40 per cent.

Gleichzeitig ergibt sich aus der niedrigen Behandlungstemperatur der bedeutende Vor.-teil, daß das Fett keiner Veränderung unterworfen wird, wie es bei, einer Behandlung bei höheren Temperaturen der Fall ist.At the same time, the low treatment temperature results in the significant advantage, that the fat is not subject to any change becomes, as is the case with treatment at higher temperatures.

Das Veriebreli.,_ kann . in_der' Praxis durch bekannte Mittel ausgeführt werden, z. B. indem vor der Erwärmung des Autoklavs Luft, Sauerstoff oder irgendein zweckmäßiges Gas unter Druck in denselben eingeführt wird, oder indem das Konzentrat mit Hilfe einer Pumpe in der Autoklav gedrückt und mittels dieser Pumpe der gewünschte Druck im Autoklav erzeugt wird.The Veriebreli., _ Can. carried out in practice by known means be e.g. B. by prior to heating the autoclave air, oxygen or any appropriate gas is introduced into the same under pressure, or by adding the concentrate with the help of a pump in the autoclave and with this pump the desired Pressure is generated in the autoclave.
