Rückgewinnungsvorrichtung für organische LösungsmittelOrganic solvent recovery device
Die Erfindung betrifft eine Rückgewinnungsvorrichtung für organische Lösungsmittel wie Perchloräthylen aus Luft durch Adsorption an Aktivkohle und Desorption mittels Spüldampf, mit einem Aktivkohlebehälter, der durch Rohrleitungen mit einem Dampferzeuger und einem Kondensator für den Spüldampf sowie das von diesem mitgenommene Lösungsmittel verbunden ist.The invention relates to a recovery device for organic solvents such as perchlorethylene Air by adsorption on activated carbon and desorption by means of purge steam, with an activated carbon canister, the through pipes with a steam generator and a condenser for the purge steam and that of this entrained solvent is connected.
Bekannte Vorrichtungen dieser Art benutzen Dampf, der von einem zentralen Dampferzeuger beispielsweise einer Fabrik hergestellt und über betriebsinterne Rohrleitungen dem Aktivkohlebehälter zugeführt wird. Für kleine Betriebe, wie Reinigungsunternehmen, welche das in einer Reinigungsmaschine benutzte Perchloräthylen zurückgewonnen wollen und müssen, sind derartige Anlagen ungeeignet. In solchen Fällen muß der Dampf speziell für diesen Verwendungszweck erzeugt und auf einfache Weise in den Aktivkohlebehälter geleitet werden.Known devices of this type use steam from a central steam generator, for example one Factory manufactured and fed to the activated charcoal canister via in-house pipelines. For small businesses, such as cleaning companies, which the perchlorethylene used in a cleaning machine must and want to be recovered are such Systems unsuitable. In such cases the steam must be generated and used specifically for this purpose can easily be fed into the activated charcoal canister.

Für diesen Anwendungsfall ist bereits eine Rückgewinnungsvorrichtung vorgeschlagen worden, bei der der Aktivkohlebehälter und der Dampferzeuger nicht durch Rohrleitungen miteinander verbunden, sondern in einem Gehäuse vereinigt sind, wobei der Dampferzeuger nach Art eines oben offenen Topfes unterhalb des Aktivkohlebehälters angeordnet ist. Dies hat jedoch den Nachteil, daß der Dampferzeuger, dessen Oberfläche in der Regel kleiner als die Querschnittsfläche der Aktivkohle im Aktivkohlebehälter ist, so daß die Durchdringung der Aktivkohle mit Spüldampf über jenen Querschnitt ungleichmäßig ist.A recovery device is already available for this application has been proposed in which the charcoal canister and the steam generator fail Pipelines connected to each other, but are combined in one housing, the steam generator is arranged in the manner of an open-topped pot below the activated charcoal container. However, this has the Disadvantage that the steam generator, its surface is usually smaller than the cross-sectional area of the activated carbon in the activated carbon container, so that the penetration the activated carbon with purging steam is uneven across that cross-section.
j Diesen Nachteil beseitigt die Erfindung, vom eingangsj This disadvantage eliminates the invention from the beginning

Auf diese Weise wird der Spüldampf gleichmäßig verteilt in den Aktivkohlebehälter | 4 eingeleitet, so daß dort die Desorption des Lösungs-Based on the described prior art, characterized in that the steam generator and the activated charcoal canister through several, essentially parallel pipelines are connected. In this way, the purge steam evenly distributed in the activated charcoal canister | 4 initiated so that the desorption of the solution

hälter im Sinne der Dampfkesselbestimmungen ist. In diesem Falle bedarf es nicht der Abnahme des Dampferzeugers durch den technischen Überwachungsverein, worauscontainer in the sense of the steam boiler regulations. In this case, the steam generator does not need to be approved by the technical monitoring association, from what

Für die Montage, Reinigung, Wartung und Reparatur der Einzelaggregate der erfindungsgemäßen Vorrichtung ist es von Vorteil, wenn Rohrstutzen am Dampferzeuger und Aktivkohlebehälter durch dampffeste Schläuche verbunden sind. Auf diese Weise lassen sich der Dampferzeuger § und der Aktivkohlebehälter voneinander lösen. Auch kannFor the assembly, cleaning, maintenance and repair of the individual units of the device according to the invention is it is an advantage if pipe sockets on the steam generator and Activated charcoal canisters are connected by vapor-proof hoses. In this way, the steam generator § and detach the activated charcoal canister from each other. Also can

Wenn die Rohrstutzen in den Innenraum des Aktivkohlebehälters hineinragen, und wenn dessen Boden zu einem Wasserablauf hin geneigt ist, so wird der Boden des Aktivkohlebehälters gleichzeitig zu einem Kondenswasserfanger, für den kein besonderes Bauteil mehr vorgesehen zu werden braucht.If the pipe socket protrudes into the interior of the activated charcoal canister, and if its bottom becomes a The water outlet is inclined, the bottom of the activated charcoal canister becomes a condensation water trap at the same time, for which no special component needs to be provided.
In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Rückgewinnungsvorrichtung schematisch veranschaulicht, und zwar zeigtIn the drawing is an embodiment of the invention Recovery device illustrated schematically, namely shows

Im Aktivkohlebehälter 1 ist die Aktivkohle auf einem Siebboden 7 in bekannter Weise aufgeschichtet. Durch einen Rohrstutzen wird die mit einem Lösungsmittel, beispielsweise Perchloräthylen, angereicherte Luft angesaugt und nach Durchgang durch die Aktivkohle, welche das Lösungsmittel adsorbiert, durch den Rohrstutzen 9 wieder abgegeben. In the activated charcoal container 1, the activated charcoal is stacked on a sieve bottom 7 in a known manner. Through a The air enriched with a solvent, for example perchlorethylene, is sucked in and the pipe socket after passing through the activated carbon, which adsorbs the solvent, released again through the pipe socket 9.
Im Dampferzeuger 2 wird mittels elektrischer Heizschlangen Dampf erzeugt, welcher durch mehrere, im wesentlichen parallele und nur leicht divergierende Rohrleitungen 3 in den Aktivkohlebehälter 1, und zwar durch dessen Boden 10 eingeleitet wird. Die Rohrleitungen 3 bestehen aus Rohrstutzen 11 am Dampferzeuger 2, Rohrstutzen 12 am Aktivkohlebehälter 1 und diese Rohrstutzen 11,12 verbindende dampffeste Schläuche 13.In the steam generator 2 is by means of electrical heating coils Generates steam, which through several, essentially parallel and only slightly diverging pipes 3 is introduced into the activated charcoal canister 1 through the bottom 10 thereof. The pipes 3 consist of Pipe socket 11 on the steam generator 2, pipe socket 12 on the Activated charcoal container 1 and steam-resistant hoses 13 connecting these pipe sockets 11, 12.

Der Boden 10 des Aktivkohlebehälters ist zu einem Wasserablauf 14 hin geneigt, und die Rohrstutzen 12 ragen etwas in den Innenraum des Aktivkohlebehälters 1 hinein. Oberhalb der Rohrstutzen 12 ist im Aktivkohlebehälter 1 ein Überhitzer 4 für den Spüldampf vorgesehen. The bottom 10 of the activated charcoal container is inclined towards a water drain 14, and the pipe sockets 12 protrude somewhat into the interior of the activated charcoal container 1. Above the pipe socket 12 is in the activated charcoal canister 1 a superheater 4 is provided for the purge steam.
Über die Rohrleitung 15 wird der mit desorbiertem Lösungsmittel angereicherte Spüldampf in den Kondensator geleitet; das Kondensat gelangt in einen Wasserabscheider 6, in den auch der Wasserablauf 14 mündet. Aus dem Wasserabscheider wird in bekannter Weise auch das rückgewonnene Lösungsmittel abgeführt.The flushing steam enriched with desorbed solvent is fed into the condenser via the pipe 15 directed; the condensate reaches a water separator 6, into which the water drain 14 also opens. From the The recovered solvent is also removed from the water separator in a known manner.
