Diese Aufgabe wird verfahrensgemäß durch die Merkmale des Anspruches 1 gelöst.This object is achieved according to the method by the features of claim 1.
Herkömmliche Verfahren sehen eine Verschwelung der Trägermaterialien mit der Aktivkohle vor. Beispielsweise erfolgt in einem Drehrohrofen, wie er bislang zur Anwendung gelangt, eine Hitzezufuhr an die Außenoberfläche der Aktivkohle, wodurch die Poren der Aktivkohle verklebt werden und die Leistungsfähigkeit der Aktivkohle eine Einbuße erleidet.Conventional methods provide for charring the carrier materials with the activated carbon. For example, in a rotary kiln, as has previously been used, a heat input to the outer surface of the activated carbon, whereby the pores of the activated carbon are bonded and the performance of the activated carbon suffers a loss.
Bei dem erfindungsgemäßen Verfahren können beispielsweise die folgenden Qualitätsparameter bei der Recyclingaktivkohle erreicht werden:
Die erfindungsgemäß wiedergewonnene Aktivkohle ist folglich uneingeschränkt – ohne nennenswerte Qualitätsverluste – wieder einsatzfähig.The recovered according to the invention activated carbon is therefore fully - without significant quality losses - again operational.
Bei dem erfindungsgemäßen Verfahren ist die Mikrowellenstrahlung mit Heißgas und mit der Heizstrahlung kombiniert.In the method according to the invention, the microwave radiation is combined with hot gas and with the heating radiation.
Zur Erzeugung der Mikrowellenstrahlung wird bei dem erfindungsgemäßen Verfahren mindestens eine Mikrowellenstrahlenquelle verwendet. Zweckmäßigerweise kommen eine Anzahl Mikrowellenstrahlenquellen zur Anwendung.To generate the microwave radiation, at least one source of microwave radiation is used in the method according to the invention. Conveniently, a number of microwave radiation sources are used.
Zur Erzeugung der Heizstrahlung wird eine elektrische Widerstandsheizung verwendet. Eine derartige elektrische Widerstandsheizung ist einfach und präzise an die jeweiligen Erfordernisse anpassbar, um die Kunststoffmatrix der kohlenstofffaserverstärkten Kunststoffgegenstände und/oder den Aktivkohleträger der mit Aktivkohlepartikeln ausgerüsteten Gegenstände zu verbrennen, um die Kohlenstofffasern und/oder die Aktivkohlepartikel zurückzugewinnen.To generate the heating radiation, an electrical resistance heater is used. Such electrical resistance heating is easily and precisely adaptable to the respective requirements to burn the plastic matrix of the carbon fiber reinforced plastic articles and / or the activated carbon carrier of the activated carbon particle-equipped articles to recover the carbon fibers and / or the activated carbon particles.
Die Verbrennungs-Abgase werden aus der Prozesskammer ausgeleitet und in einer Nachbehandlungseinrichtung nachbehandelt, d. h. gesundheitsgefährdende Bestandteile der Verbrennungsabgase ausgefiltert.The combustion exhaust gases are discharged from the process chamber and aftertreated in an aftertreatment device, i. H. harmful components of the combustion gases filtered out.
Erfindungsgemäß werden die Gegenstände durch die Prozesskammer hindurch bewegt werden. Es handelt sich um ein dynamisches Verfahren (Durchlaufofen).According to the invention, the articles will be moved through the process chamber. It is a dynamic process (continuous furnace).
Die der Erfindung zugrunde liegende Aufgabe wird vorrichtungsgemäß durch die Merkmale des Anspruches 2 gelöst. Die Prozesskammer ist als Durchlaufofen ausgebildet, dem eine Vorschubeinrichtung für die zu behandelnden Gegenstände zugeordnet ist. Die Vorschubeinrichtung kann hierbei ein Endlosband aufweisen.The object underlying the invention is achieved according to the device by the features of claim 2. The process chamber is designed as a continuous furnace, which is associated with a feed device for the objects to be treated. The feed device can in this case have an endless belt.
Die Prozesskammer ist als Durchlaufofen ausgebildet, wobei dieser eine Anzahl hintereinander angeordnete Kammermodule aufweist, von welchen jeder mindestens eine Mikrowellen-Strahlenquelle aufweist. Ein derartiger Mikrowellen-Durchlaufofen ist bspw. in der
Die Mikrowellenstrahlenquellen der hintereinander angeordneten Kammermodule sind in Umfangsrichtung der Prozesskammer gegeneinander versetzt vorgesehen, so dass sich in der Prozesskammer zur Vermeidung von Hotspots quasi ein schraubenlinienförmiges Mikrowellen-Strahlenfeld vorteilhaft ergibt.The microwave radiation sources of the chamber modules arranged one behind the other are provided offset relative to one another in the circumferential direction of the process chamber, so that a helical microwave radiation field results quasi in the process chamber to avoid hotspots.
Wie bereits erwähnt worden ist, kann die der Prozesskammer zugeordnete Vorschubeinrichtung ein Endlosband aufweisen, das sich mit einem Vorschubtrum durch die Prozesskammer hindurch erstreckt. Desgleichen ist es möglich, dass die Vorschubeinrichtung eine Rollenbahn oder eine Hubbalken-Transporteinrichtung aufweist.As has already been mentioned, the feed device associated with the process chamber may comprise an endless belt which extends through the process chamber with a feed strand. Likewise, it is possible that the feed device has a roller conveyor or a lifting beam transport device.
Um einen ungewollten Austritt von Mikrowellenstrahlung aus der Prozesskammer zu verhindern, weist die Prozesskammer vorzugsweise einlassseitig und auslassseitig jeweils einen Mikrowellen-Absorbertunnel auf.In order to prevent an unwanted escape of microwave radiation from the process chamber, the process chamber preferably has a respective microwave absorber tunnel on the inlet side and the outlet side.
Die elektrische Widerstandsheizung ist dem Vorschubtrum der Endlosband-Vorschubeinrichtung zugeordnet, d. h. unter diesem angeordnet.The electrical resistance heating is associated with the feed strand of the endless belt feed device, d. H. arranged under this.
Die Prozesskammer weist eine, vorzugsweise beheizte, Abzugeinrichtung für die in der Prozesskammer generierten Verbrennungs-Abgase auf. Die Abzugeinrichtung ist zweckmäßigerweise mit einer Abgas-Nachbehandlungseinrichtung verbunden. In der Abgas-Nachbehandlungseinrichtung werden gesundheitsgefährdende Bestandteile des Abgases nachverbrannt bzw. ausgefiltert. Gesundheitsgefährdente Bestandteile gelangen nicht in die Umgebung.The process chamber has a, preferably heated, discharge device for the combustion exhaust gases generated in the process chamber. The removal device is expediently connected to an exhaust gas aftertreatment device. In the exhaust aftertreatment device harmful components of the exhaust gas burned or filtered out. Hazardous ingredients do not enter the environment.
