Description

Vorrichtung zur Gewinnung von vergasten organischen Körpern durch Adsorptionsmittel.Device for the extraction of gasified organic bodies Adsorbent.

Die Abscheidung von vergasten organischen Körpern, wie Benzol, Äther, Aceton, aus ihren Gemischen mit Luft oder anderen nicht oder schwer adsorbierbaren Gasen, wie z. B. Wasserstoff, Ammoniak usw., läßt sich am vorteilhaftesten durch Kohle oder andere Adsorptionsmittel durchführen. Es ist bereits bekannt, die Befreiung des Adsorbens von den adsorbierten Körpern zwecks Gewinnung der letzteren durch Behandlung mit Wasserdampf herbeizuführen. The separation of gasified organic bodies, such as benzene, ether, Acetone, from their mixtures with air or other adsorbable or difficult to adsorb Gases such as B. hydrogen, ammonia, etc., can be most advantageous through Carry out charcoal or other adsorbent. It is already known the exemption of the adsorbent from the adsorbed bodies for the purpose of recovering the latter Induce treatment with steam.

Auch die Anwendung von Hitze, gegebenenfalls imVakuum, für den genannten Zweck ist bekannt.Also the application of heat, possibly in a vacuum, for the mentioned The purpose is known.

Ersteres Verfahren zur Befreiung des Adsorbens von den adsorbierten Körpern hat den Nachteil, daß das Trocknen der Adsorptionskohle nach dem Ausdämpfen einige Zeit in Anspruch nimmt. Nach dem anderen Verfahren ist es nicht möglich, die Adsorptionsfähigkeit der Kohle voll auszunutzen, da diese beim Erhitzen im Vakuum noch immer beträchtliche Mengen des adsorbierten organischen Körpers zurückhält. Die zurückgehaltenen Mengen sind dabei von der Höhe der Erwärmung abhängig.The former method of removing the adsorbed from the adsorbent Bodies has the disadvantage that the drying of the adsorption carbon after steaming out takes some time. With the other method it is not possible to to fully utilize the adsorptive capacity of the charcoal, as this occurs when heated in a vacuum still retains significant amounts of the adsorbed organic matter. The quantities retained depend on the level of warming.

Während im kleinen eine einigermaßen gleichmäßige Erhitzung des Gefäßes mit Adsorptionskohle erreicht werden kann, ließ sich dieses Verfahren in der Technik nicht einführen.While on a small scale a fairly even heating of the vessel can be achieved with adsorption charcoal, this process settled in the art do not introduce.

Es wurde nun festgestellt, daß sich die technische Anwendung des Verfahrens ermöglichen läßt, wenn für schnellen Wärmeaustausch innerhalb des Adsorptionsgefäßes gesorgt wird. Dies wird gemäß der Erfindung dadurch erreicht, daß der Behälter, der das Adsorptionsmittel (Kohle) enthält, mit einem System von Kühl- bzw. Heizkörpern derart versehen wird, daß die jeweils zwischen einzelnen Kühl- und Heizflächen liegenden Schichten dünn sind. Es ist dabei erforderlich, die Heizkörper so zu wählen, daß die Unterteilung der Absorptionsmassen in dünne, senkrecht zur Gasrichtung liegende, also wagerechte Schichten erfolgt. Dies erreicht man zum Beispiel durch ein System von horizontalen Heizschlangen, welche einzeln parallel oder hintereinandergeschaltet werden können. So kann man das Kühlen oder Erhitzen an denjenigen Stellen der Absorptionsmasse ausführen, wo der Arbeitsvorgang es erfordert. Man erhält so Absorptionsapparate von großer Kapazität an Absorptionsmassen, welche den Durchgang von Gasen nur geringen und gleichmäßigen Widerstand bieten und sich dadurch vorteilhaft von den mit geraden, senkrechten Heizrohren ausgestatteten Apparaten unterscheiden. Dadurch wird auch erzielt, daß man große Temperaturdifferenzen rasch herstellen kann, so daß der Wirkungsgrad des Verfahrens ein sehr hoher wird. Bei einer Ausführungsform der vorstehend bezeichneten Vorrichtung wird das Adsorptionsgefäß von einzelnen Rohrleitungen durchzogen, die zum Umlauf von Kühlwasser oder Kühllösungen bzw. von Wasserdampf dienen. Während der Adsorption wird Kühlwasser oder besser Kühllösung durch die Rohre geleitet; beim Austreiben des adsorbierten Körpers dienen sie zur Aufnahme von Wasserdampf. Zur Erhohung der Wirkung erfolgt die Austreibung des adsorbierten Körpers unter Vakuum. It has now been found that the technical application of the Allow process if for rapid heat exchange within the adsorption vessel is taken care of. This is achieved according to the invention in that the container, containing the adsorbent (coal), with a system of cooling or heating elements is provided in such a way that each lying between individual cooling and heating surfaces Layers are thin. It is necessary to choose the radiator so that the subdivision of the absorption masses into thin, perpendicular to the gas direction, so there are horizontal layers. This can be achieved, for example, through a system of horizontal heating coils, which are individually connected in parallel or in series can be. So you can cool or heat at those points of the absorption mass perform where the work requires it. Absorption apparatuses are obtained in this way of great capacity of absorption masses, which the passage of gases only slight and offer even resistance and thereby stand out from those with straight, differentiate between apparatus equipped with vertical heating pipes. This will also achieved that you can quickly produce large temperature differences, so that the efficiency the procedure becomes a very high one. In one embodiment of the above The device is traversed by individual pipes, the adsorption vessel serve to circulate cooling water or cooling solutions or water vapor. While the adsorption, cooling water or better cooling solution is passed through the tubes; when expelling the adsorbed body, they serve to absorb water vapor. To increase the Effect is the expulsion of the adsorbed Body under vacuum.
