Description
Verfahren zur Regenerierung von Adsorbentien Bekanntlich können mit Hilfe von Aktivkohle oder anderen Stoffen, die adsorptive Eigenschaften aufweisen, Verunreinigungen, insbesondere Schwefelverbindungen oder Lösungsmittel aus Abgasen auf adsorptivem Wege entfernt werden. Fu~r die Regeneration der beladenen Adsorptionsmittel gibt es dabei verschiedene Möglichkeiten, entweder man desorbiert die an dem Adsorbens gebundenen Stoffe durch Erhitzung mit heißen Inertgasen, mit Wasserdampf oder durch heiße Inertfeststoffe oder man wäscht die gebundenen Stoffe mit Wasser oder wäßrigen Lösungen aus, um das regenerierte Adsorptionematerial wieder in den Reinigungsprozeß einsetzen zu können.Process for the regeneration of adsorbents It is known that with The help of activated carbon or other substances that have adsorptive properties, Impurities, especially sulfur compounds or solvents from exhaust gases be removed by adsorptive means. For the regeneration of the loaded adsorbent There are different possibilities, either one desorbs the one on the adsorbent bound substances by heating with hot inert gases, with steam or by hot inert solids or the bound substances are washed with water or aqueous Solutions to get the regenerated adsorption material back into the cleaning process to be able to use.
Zu diesem Zweck ist es bekannt, das Adsorbens in einem Festbett diskontinuierlich zu beladen und zu regenerieren. Bei den hierfür bekannten Vorrichtungen erfolgen die einzelnen Prozeßvorgänge diskontinuierlich durch Umschaltung auf die einzelnen Adsorp tionseinheiten. Bedingt durch den diskontinuierlichen Betrieb und die dadurch erforderliche Anzahl von Adsorptionseinheiten entstehen hohe Investitionskosten für die aufwendige Steuerung und die Apparate.For this purpose it is known to discontinue the adsorbent in a fixed bed to load and regenerate. Take place in the devices known for this purpose the individual process operations discontinuously by switching over to the individual ones Adsorption units. Due to the discontinuous operation and the resulting required number of adsorption units result in high investment costs for the complex control and the equipment.
Es ist weiterhin bekannt, das beladene Adsorbens mit aufgeheiztem inertem Feststoffmaterial, beispielsweise mit heißem Sand, in einem separaten Regenerationsreaktor in Berührung zu bringen und so die adsorbierten Stoffe aus dem Adsorptionsmaterial zu entfernen.It is also known that the loaded adsorbent with heated inert solid material, for example with hot sand, in a separate regeneration reactor to bring into contact and so the adsorbed substances from the adsorption material to remove.
Bei der Reinigung von Rauchgasen mit Hilfe von Adsorberkoksen wird beispielsweise das Schwefeldioxyd als Schwefelsäure auf dem Koks gebunden. Bei der Regeneration wird die gebundene Schwefelsäure zu Schwefeldioxyd reduziert, wobei ein S02-Reichgas entsteht.When cleaning flue gases with the help of adsorber coke For example, the sulfur dioxide bound as sulfuric acid on the coke. In the Regeneration reduces the bound sulfuric acid to sulfur dioxide, whereby an S02 rich gas is produced.
Die Aufheizung und die Kreislaufführung des festen Wärmeträgers sowie die Trennung des Wärmeträgers von dem Adsorbens erfordert einen sehr großen apparativen Aufwand. Die Betriebsmittelkosten sind außerdem enorm hoch.The heating and the circulation of the solid heat carrier as well the separation of the heat carrier from the adsorbent requires a very large amount of equipment Expenditure. The operating costs are also extremely high.
Eine weitere Möglichkeit, das beladene Adsorptionsmittel zu regenerieren, besteht darin, es in einer Wanderschicht mit Wasser oder einer w§rigen Loung aussutauschon Dabei fällt eine schwach konzentrierte Schwefelsäure an, deren Aufkonzentrierung hohe Kosten verursacht.Another way to regenerate the loaded adsorbent, consists of exchanging it in a walking layer with water or an aqueous lounge This results in a weakly concentrated sulfuric acid, its concentration causes high costs.
Der Erfindung liegt die Aufgabe-zugrunde, die oben geschilderten Nachteile zu vermeiden und eine wirksame Regeneration des Adsorptionsaittols auf wirtschaftliche Weise zu ermöglichen. Gegenstand der Erfindung ist ein Verfahren zur Regenerierung von festen Adsorptionsiitteln, die zur adsorptiven Entfernung von Verunreinigungen. insbesondere von Lösungsmitteln und/oder Schwefelverbindungen aus Abgasen eingesetzt waren, durch trokkene Wärmebehandlung, das dadurch gekennzeichnet ist, daß die mit den Abgasverunreinigungen beladenen Adsorptionsmittel in einen Regenerationsreaktor eingeführt und durch Erhitzung mit Hilfe von Mikrowellen regeneriert werden, wobei die adsorbierten Stoffe desorbiert werden und in konzentrierter Form anfallen.The object of the invention is to address the disadvantages outlined above to avoid and an effective regeneration of the Adsorptionsaittol on economic Way to enable. The invention relates to a method for the regeneration of solid adsorbents which are used for adsorptive removal of impurities. especially of solvents and / or sulfur compounds from exhaust gases were used by dry heat treatment, which is characterized is that the adsorbents loaded with the exhaust gas pollutants in one Regeneration reactor introduced and regenerated by heating with the help of microwaves The adsorbed substances are desorbed and in concentrated form attack.

Beim erfindungsgemäßen Verfahren sind Adsorptions-und Regenerations-Reakt@ren nur durch eine Sperrstrecke miteinander verbunden. Ein vom Adsorptionsmittelkreislauf gesonderter Wärmeträgerkreislauf zur Aufheizung des Adsorbens und zur Desorption der adsorbierOen Stoffe entfällt hierbei. Die Regeneration erfolgt vielmehr durch direkte Erwärmung des Adsorbens und/oder des adsorbierten Stoffes in einem Regenerationsreaktor mit Hilfe von Mikrowellen. Die Regenerationstemperatur kann hierbei den einzelnen Erfordernissen beliebig angepaßt werden. Die Reaktionsprodukte wie z. B. SO2-Reichgase bei der Rauchgasent@chwefelung oder Lösungenitteldämpfe werden in konzentrierter Form abgesaugt und der Weiterbearbeitung bzw. Wiederverwendung zugeführt. In einzelnen ergeben sich folgende Vor#eile: 1. Bei Anlagen zur Ent#ernunS von Schwefelverbindun#en.A so-called dry process is used for this, i.

In the method according to the invention Adsorption and regeneration reactors are only interconnected through a blocking section tied together. A separate heat carrier circuit from the adsorbent circuit for There is no need to heat the adsorbent or desorb the adsorbed substances. Rather, the regeneration takes place by direct heating of the adsorbent and / or of the adsorbed substance in a regeneration reactor with the aid of microwaves. The regeneration temperature can be adapted as desired to the individual requirements will. The reaction products such as. B. SO2 rich gases in flue gas desulfurization or solvent vapors are extracted in concentrated form and used for further processing or recycled. In some cases, the following advantages result: 1. In systems for removing sulfur compounds.
1.1 Ein gesonderter Kreislauf für Wärmeträger mit den dafür erforderlichen Apparaten entfällt. Durch die direkte Erwärmung mit Hilfe von Mikrowellen wird die zur Regeneration des Adsorbens erforderliche Wärme ohne zusätzliche Hilfsmittel zugeführt 1.2 Das Adsorbens wird mechanisch und thermisch nicht so stark beansprucht wie bei der Erwärmung mit Wärmeträgern.1.1 A separate circuit for heat transfer media with the necessary Apparatus is not required.

1.3 Ein Trennen von Adsorbens und Wärmeträgern entfällt.1.3 There is no need to separate adsorbent and heat transfer media.
