Description
Verfahren zur Wiedergewinnung von in Adsorptionsmitteln aufgenommenen Gasen oder Dämpfen und Regeneration der Adsorptionsmittel Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Wiedergewinnung der von Adsorptionsmitteln, wie z. B. aktiver Kohle, Kieselsäuregel o. dgl., aufgenommenen Gase oder Dämpfe und zur Regeneration, insbesondere Kühlung der Adsorptionsmittel.Process for the recovery of adsorbents taken up Gassing or Vapors and Regeneration of Adsorbents The invention relates to a method and a device for the recovery of adsorbents, such as B. active charcoal, silica gel o. The like., Absorbed gases or vapors and for regeneration, especially cooling, of the adsorbents.
Nach bekanntem Verfahren nimmt man die Austreibung adsorbierter Stoffe aus den Adsorptionsmitteln in der Weise vor, daß man Gase im Kreislauf bei erhöhter Temperatur durch das Adsorptionsmittel leitet und die entbundenen Stoffe alsdann durch Kühlung der Gase abscheidet.By a known method to take t before the expulsion of adsorbed substances from the adsorbents in such a way that gases in the circuit passes at elevated temperature through the adsorbent and then debonded materials by cooling of the gases is deposited.
Um die Adsorptionsmassen nach beendigter Austreibung der adsorbierten Stoffe wieder aufnahmefähig zu machen, ist eine Kühlung derselben notwendig. ' Erfindungsgemäß nimmt man die Kühlung der Adsorptionsmittel in der Weise vor. daß man im Anschluß an die Austreibeperiodemit im Kreislauf geführten inerten Gasen oder dem ursprünglichen zu zerlegenden Gasgemisch die gleichen Gase, die zur Austreibung benutzt worden sind, auch weiterhin im Kreislauf führt, jedoch ohne sie, wie es während der Austreibeperiode der Fall war, an bestimmten Stellen des Kreislaufes vor Eintritt in den auszublasenden Adsorber zu erhitzen. Man kühlt vielmehr das im Umlauf befindliche Gas in geeigneter Weise. Die Kühlwirkung kann zweckmäßig noch dadurch erhöht werden, daß die Adsorptionsmittel mittels eines durch eine im Adsorber angeordnete Kühlvorrichtung geführten kalten Mediums abgekühlt «-erden.To the adsorption masses after the expulsion of the adsorbed To make substances absorbent again, it is necessary to cool them. 'According to the invention one takes the cooling of the adsorbent in the way. that one in the connection to the expulsion period with recirculated inert gases or the original The gas mixture to be decomposed is the same as that used for expulsion continue to circulate, but without them, as is the case during the expulsion period the case was to be blown out at certain points in the circuit before entering the Heat adsorber. Rather, the gas in circulation is cooled in a suitable manner Way. The cooling effect can expediently be increased by the fact that the adsorbent by means of a cold that is passed through a cooling device arranged in the adsorber Medium cooled ”- earth.
Die -beiliegende Zeichnung zeigt eine beispielsweise Ausführung der Erfindung.The accompanying drawing shows an example of the execution of the Invention.
A bezeichnet einen mit Adsorptionsmitteln, wie z. B. Al,-dvkohle. Kieselsäuregel o. d,-L, gefüllten Adsorber. Während der Adsorptionsperiode wird das zu behandelnde Gas durch die Leitung a in den Adsorber A eingeführt und nach Abgabe der adsorbierbaren., Bestandteile durch die Leitung b abgeführt. Ist der Adsorber A beladen, so harn auf einen zweiten Adsorber umgeschaltet werden. Während der folgenden Austreibeperiodewird durch die Pumpe P aus der Leitung a durch die Leitung c eine gewisse Menge des zu behandelnden Gasgemisches angesaugt und im Kreislauf auf Pd Fe Af K, g K2 h P geführt. In dem Erhitzer E findet eine Erhitzung des Gases statt, in dem Kühler 1K1 eine Kühlung und in dem Kondensator K2 eine Abscheidung der verflüssigten entbundenen Stoffe. Die nicht kondensierten Gase werden durch P angesaugt und weiter im Kreislauf geführt, gegebenenfalls unter Zwischenschaltung der Leitung k und des Kühlers K1, um die dort frei werdende Wärmemenge mit zur Rufheizung des Gases zu verwenden. Bei V ist ein Ventil eingebaut, das sich nur öffnet, wenn in der Kreislaufkühlung ein bestimmter einstellbarer Druck unterschritten wird, so daß also nur eine gewisse Gasmenge aus der Leitunga angesaugt wird. Bei Verwendung eines anderen Gases, wie z. B. Kohlensäure, an Stelle des zu zerlegenden ursprünglichen Gasgemisches schaltet man die Leitung! ein und die Leitung c ab. Auch hierbei findet eine Regelung der angesaugten Gasmenge durch das Ventil V statt.A denotes one with adsorbents, such as. B. Al, carbon. Silica gel o. D, -L, filled adsorber. During the adsorption period, the gas to be treated is introduced into adsorber A through line a and, after the adsorbable components have been released, is discharged through line b. If the adsorber A is loaded, a second adsorber must be used. During the following expulsion period, a certain amount of the gas mixture to be treated is sucked in by the pump P from the line a through the line c and circulated to Pd Fe Af K, g K2 h P. The gas is heated in the heater E , cooling in the cooler 1K1 and the liquefied, released substances are separated out in the condenser K2. The non-condensed gases are sucked in through P and further circulated, if necessary with the interposition of the line k and the cooler K1, in order to use the amount of heat released there to heat the gas. At V there is a built-in valve which only opens when the pressure drops below a certain adjustable pressure in the circuit cooling, so that only a certain amount of gas is sucked in from the line a. When using another gas, such as. B. carbon dioxide, instead of the original gas mixture to be broken down, you switch the line! on and line c off. Here, too, the amount of gas sucked in is regulated by the valve V.
Die Austreibung der adsorbierten Stoffe kann noch durch eine indirekte Erhitzung des Adsorptionsmittels mit Hilfe von im Adsorber angeordneten Heizvorrichtungen H, die durch die Dampfleitung l gespeist werden, verstärkt werden. Das aus der Heizverrichtung austretende Heizmittel wird dann noch zweckmäßig zur Erhitzung des Kühlers der durch die Leitung m mit H verbunden ist, verwendet.The expulsion of the adsorbed substances can be intensified by indirect heating of the adsorbent with the aid of heating devices H which are arranged in the adsorber and which are fed through the steam line 1. The heating medium emerging from the heating device is then expediently used to heat the cooler, which is connected to H by the line m .
Sind die adsorbierten Stoffe ausgetrieben, so schließt sich sogleich an die Austreibeperiode eine Kühlperiode an, indem die im Kreislauf umgewälzte Menge unter Ausschaltung jeder Wiederaufheizung im Kreislauf Af K1 g K2 7t Pd pe A weitergeführt wird. Die aus A fortgeführte Wärmemenge wird im Kühler K1 vernichtet. Zweckmäßig kann man die Kühlwirkung noch dadurch unterstützen, daß man durch die Vorrichtungen H ein Kühlmittel leitet. Natürlich kann die Gasmenge auch bei dieser Kühlperiode durch das selbsttätige Ventil V geregelt werden.Are the adsorbed substances expelled, then a cooling period closes immediately at the Austreibeperiode by the circulating in the circulation volume will continue while eliminating any reheating in the circuit K1 Af g K2 7t Pd pe A. The amount of heat carried on from A is destroyed in the cooler K1. The cooling effect can expediently be supported by passing a coolant through the devices H. Of course, the amount of gas can also be regulated by the automatic valve V during this cooling period.
Das Verfahren ist mit besonderem Vorteil anwendbar bei Hintereinanderschaltung von zwei oder mehreren Adsorbern sowie auch, wenn man die Kondensation der aus dem Adsorptionsmittel abgetriebenen Dämpfe unter Druck vorgenommen hat.The method can be used with particular advantage when connected in series of two or more adsorbers as well as, if one considers the condensation of the from the Adsorbent has made expelled vapors under pressure.
Vorteilhaft kann man auch mit mehreren Adsorbern in der Weise arbeiten, daß während des Austreibens der adsorbierten Stoffe und des Kühlens des einen Adsorbers im anderen Adsorber oder in anderen Adsorbern gleichzeitig die Beladung stattfindet.It is advantageous to work with several adsorbers in such a way that that during the expulsion of the adsorbed substances and the cooling of one adsorber the loading takes place at the same time in the other adsorber or in other adsorbers.
Das Verfahren gemäß der Erfindung ist insofern von besonderem Vorteil, als die Betriebsführung der Anlage ganz wesentlich vereinfacht wird. Die benötigte Gasmenge braucht nur verhältnismäßig klein zu sein, und es bedarf nur einiger weniger Ventilumstellungen, um von der Austreibeperiode auf die Kühlperiode überzugehen. Außerdem ist das Kühlmittel das gleiche wie das Austreibemittel, was die Wirtschaftlichkeit des gesamten Verfahrens wesentlich erhöht. Eine weitere Verbesserung der Wirtschaftlichkeit und Vereinfachung der Betriebsführung liegt in dem Fortfall einer besonderen Trockenperiode. für das Adsorptionsmittel.The method according to the invention is particularly advantageous in that as the operational management of the plant is considerably simplified. The one needed The amount of gas only needs to be relatively small, and only a few are required Valve changes in order to pass from the expulsion period to the cooling period. Also, the coolant is the same as the expelling agent, which is economical of the entire procedure increased significantly. Another improvement in profitability and simplification of the operational management lies in the elimination of a special dry period. for the adsorbent.
