Description
Verfahren zur Wiedergewinnung flüchtiger Lösungsmittel.Process for the recovery of volatile solvents.
Es ist bekannt, mit Luft flüchtige Lösungsmittel, wie z. B. Benzol, Benzin, Äther, AIkohoi usw., dadurch wiederzugewinnen, daß man das aus Luft und Lösungsmitteldampf bestehende Gemisch durch ein fettes Öl oder Fettsäure leitet und hierauf das absorbierte Lösungsmittel abdestilliert. Insbesondere ist auch vorgeschlagen worden, hierbei für eine innige Berührung des Gas-Dampf-Gemisches mit dem Fett Sorge zu tragen. It is known to react with volatile solvents such as. B. benzene, Gasoline, ether, alcohol, etc., to be recovered by making them out of air and Solvent vapor passes the mixture through a fatty oil or fatty acid and then the absorbed solvent is distilled off. In particular, it is also proposed ensure that the gas-vapor mixture comes into close contact with the fat to wear.
Gegenstand der Erfindung ist ein Verfahren, mit welchem diese Wiedergewinnung in sehr vollkommener Weise und unter Anwendtmg einer möglichst geringen Menge Öl gelingt. The invention is a method with which this recovery in succeeds very perfectly and with the application of the smallest possible amount of oil.
Zu diesem Zwecke bedient - man sich eines beispielsweise zylindrischen Behiälters, an welchem ein Zerstäuber tangential angeordnet ist. For this purpose, one uses a cylindrical one, for example Container on which an atomizer is arranged tangentially.
Durch diesen Zerstäuber wird ein fettes Öl mit dem von dem Lösungsmitteldampf zu befreienden Luft-Dampf-Gemisch unter starkem Druck in den Behälter eingeführt und innerhalb desselben in kreisförmige Umdrehung versetzt. Auf diese Weise findet eine innige Mischung und Absorption aller absorptionsfähigen Bestandteile in dem Öl augenblicklich statt. Die von dem Lösungsmitteldampf befreite Luft trennt sich in dem Behälter wieder von dem Öl und tritt durch ein durch seine Achse geführtes Rohr aus. Um mitgerissene Öltröpfchen zurückzuhalten, ist die Eintrittsöffnung in das Rohr mit einem feinmaschigen Drahtsieb verschlossen, während in seinem Innern z. B. ein schneckenförmiger Widerstand angeordnet ist.Through this atomizer, a fatty oil is mixed with that of the solvent vapor The air-steam mixture to be liberated is introduced into the container under high pressure and inside the same in circular rotation. That way finds an intimate mixture and absorption of all absorbent ingredients in the Oil instantly. The air freed from the solvent vapor separates in the container again from the oil and passes through a through its axis Pipe off. In order to hold back entrained oil droplets, the inlet opening is in the tube closed with a fine-mesh wire screen while inside it z. B. a helical resistor is arranged.
Zur Erhöhung der Wirkung kann man eine Anzahl derartiger zylindrischer Behälter, die liegend oder stehend angeordnet werden können, hintereinanderschalten, so daß das die erste Abteilung verlassende Öl mit absorbiertem Lösungsmittel jeweils durch einen weiteren Zerstäuber und frischem Luft-Da,mpf-Gemisch in die nächste, gleichgebaute Abteilung gedrückt wird, wobei aber die durch die Achse der Abteilungen geführten Rohre für den Austritt der Luft untereinander in Verbindung stehen. A number of such cylindrical ones can be used to increase the effectiveness Connect containers that can be arranged horizontally or vertically, one behind the other, so that the oil leaving the first compartment with absorbed solvent respectively through another atomizer and fresh air-Da, mpf mixture into the next, the same division is pressed, but with the through the axis of the divisions guided pipes for the outlet of the air are in connection with each other.
Die zur Ausführung des Verfahrens erforderliche, an sich bekannte Vorrichtung ist in der Zeichnung in beispielsweiser Ausführungsform im Schnitt dargestellt. The known per se required to carry out the method Device is shown in the drawing in an exemplary embodiment in section.
Die beiden zylindrischen miteinander verbundenen Behälter i und 2 sind durch die Scheidewand 3 getrennt. An dem Behälter X ist der Zerstäuber 4 tangential angeordnet. The two cylindrical interconnected containers i and 2 are separated by the partition 3. The atomizer 4 is tangential to the container X. arranged.
Mit diesem Zerstäuber 4 wird Öl durch das Luft-Dampf-Gemisch unter Druck zerstäubt in den Behälter I eingeführt, in welchem es sich kreisförmig längs der Innenwandung bewegt. Am Boden des Behälters 1 befindet sich das Rohr 8, weiches zu dem Zerstäuber 9 führt. Das Öl tritt aus dem Behälter I in das Rohr 8 und wird durch den Zerstäuber g mit einem frischen Luft-Dampf-Gemisch in den Behälter 2 gefördert, in welchem sich der gleiche Vorgang wiederholt. Den Behälter 2 verläßt das Öl durch das an seinem Boden befindliche Rohr 10.With this atomizer 4, oil is taken by the air-steam mixture Pressure atomized introduced into the container I, in which it is circular lengthways the inner wall moves. At the bottom of the container 1 is the tube 8, soft leads to the atomizer 9. The oil emerges from the container I into the pipe 8 and becomes conveyed by the atomizer g with a fresh air-steam mixture into the container 2, in which the same process is repeated. The oil leaves container 2 through the pipe 10 at its bottom.
Durch die Achse der Behälter 1 und 2 ist das Rohr 5 geführt, durch welches die Luft austritt. Der Eintritt in das Rohr 5. erfolgt durch die durch feinmaschige Drahtsiebe verschlossenen Öffnungen 6. Innerhalb des Rohres 5 befindet sich außerdem der schneckenförmige Widerstand 7, welcher von der Luft mitgerissene Oltröpfchen zurückhält. The tube 5 is guided through the axis of the container 1 and 2 which the air exits. The entry into the tube 5 takes place through the fine-meshed Wire screens closed openings 6. Inside the tube 5 is also located the helical resistor 7, which is carried away by the air droplets of oil holding back.
