Description

Verfahren und Vorrichtung zur Extraktion von organischen Stoffen Bei Extraktionsprozessen handelt es sich darum, bestimmte ßestandteile aus Substanzgemischen oder natürlichen organischen Stoffen mit Hilfe von Lösungsmitteln herauszuziehen. Der Vorgang bei der Extraktion organischer Stoffe beruht im wesentliclien auf einsleitiger oder doppelseitiger Osmose, indem das Lösungsmittel bzw. die zu extrahierende Snl>stanz durch die als Membran wirkendeZellwand des organischen Stoffes diffundiert. Die Extraktionszeit ist demzufolge al>hängig von dem Konzentratioiisgefälle zwischen den innerhalb der Zellen befindlichen Substanzen und dem außerhalb der Zellen befindlichen Lösungsmittel. Aus wirtschaftlichell Griinden ist man nun in der chemischen Technik bestrebt, die Extraktionszeit möglichst weitgehell(l herabzusetzen. Daher ist man bemüht, das konzentrat ionsgefälle während ,des Extraktionsvorganges groß zu halten. Um diesen Zweck zu erreichen, hat man schon dafür gesorgt, durch in die Extraktionsgefäße eingebaute Rührwerke den Zellenwänden stets frische, d. h. schwach konzentrierte Lösungsmittel zuzuführen. Durch dieses verhältnismäßilg rohe Verfahren konnte aber der gewünschte Zweck nur in äußerst unvollkommenem Maße erreicht werden. Zudem erfordert diese Methode einen relativ erheblichen mechanischen und Energieaufwand.Process and device for the extraction of organic substances at Extraction processes are about extracting certain components from mixtures of substances or to extract natural organic matter with the help of solvents. The process involved in the extraction of organic substances is essentially based on a one-line process or double-sided osmosis by punching the solvent or the oil to be extracted diffuses through the cell wall of the organic matter, which acts as a membrane. the The extraction time is therefore dependent on the concentration gradient between the substances located inside the cells and those located outside the cells Solvent. For economic reasons one is now in chemical engineering endeavors to reduce the extraction time as far as possible (l. Therefore, one is tries to keep the concentration gradient large during the extraction process. In order to achieve this purpose, care has already been taken to put it through the extraction vessels built-in agitators the cell walls always fresh, d. H. weakly concentrated Feed solvent. However, through this relatively crude procedure the desired purpose can only be achieved to an extremely imperfect degree. Also requires this method requires a relatively significant mechanical and energy expenditure.

Erfindungsgemäß wird nun vorgeschlagen, die Extraktion in einem hochfrequenten Schallfeld vorzunehmen und zu diesem Zweck das zu extrahierende Gut und das Lösungsmittel einem Schallfeld auszusetzen. Da nämlich die Schallwiderstände des zu extrahierendlen Gutes und des Lösungsmittels regelmäßig unterschiedlich sind, entsteht imhochfrequenten Schallfeld zwischen dem zu extrahierenden Gut und dem Lösungsmittel eine Bewegungsdifferenz. According to the invention it is now proposed that the extraction be carried out in a high frequency To undertake the sound field and, for this purpose, the material to be extracted and the solvent expose to a sound field. Because namely the sound resistance of the extracted Good and the solvent are regularly different, arises in high frequency Sound field between the material to be extracted and the solvent creates a difference in movement.

Hierdurch wird aber die erzielte Steigerung des Konzentrationsgefälles und damit die Abkürzung der Extraktionszeit in ibisher nicht erreichtem Maße erzielt.However, this increases the concentration gradient achieved and thus the reduction of the extraction time to an extent not previously achieved.

Eine Vorrichtung zur Ausführung des Verfahrens nach der Erfindung besteht z. B. aus einem Behälter zur Aufnahme des zu extrahierenden Gutes und des Lösungsmittels, in welohen ein Ultraschallerzeuger eingeführt wird. Anstatt einen Ultraschallerzeuger in den Behälter einzuführen, kann gemäß der weiteren Erfindung ein Teil des Behälters, vorzugsweise sein Boden, als Ultraschallerzeuger ausgebildet sein. An apparatus for carrying out the method according to the invention consists z. B. from a container for receiving the material to be extracted and the Solvent into which an ultrasonic generator is inserted. Instead of one Introducing ultrasound generators into the container can according to the further invention part of the container, preferably its bottom, designed as an ultrasonic generator be.
