Abstract
Description
Die Erfindung, betrifft ein Verfahren zur Entsorgung von toxische Bestandteile aufweisendem Gut, insbesondere Schwermetall enthaltenden industriellen Reststoffen.The invention relates to a method for disposal good containing toxic components, in particular Industrial residues containing heavy metal.
Aschen und andere Reststoffe und Abfälle mit Gehalten an anorganischen toxischen Bestandteilen, insbesondere Schwermetallen, sind schwierig zu entsorgen und deren Deponierung ist sehr aufwendig. Das Hauptproblem besteht in der Gefahr, daß die toxischen Bestandteile durch Wasser (Regenwasser, Grundwasser) ausgelaugt und nachfolgend in die Umgebung migrieren können.Ash and other residues and waste with contents of inorganic toxic components, in particular Heavy metals are difficult to dispose of and theirs Landfilling is very complex. The main problem is in danger of the toxic components from water (Rainwater, groundwater) leached and subsequently in can migrate the environment.
Diese Gefahr kann, wie bekannt, weitgehend dadurch minimalisiert werden, daß das Material in eine gesinterte und folglich sehr schwer auslaugbare Form überführt wird. Erst nach dem Sintern erfolgt die Deponierung oder sogar die weitere Verarbeitung, beispielsweise als künstlicher Zuschlag für den Straßenbau und als Zuschlag für Beton.As is known, this danger can largely be caused by be minimized that the material is sintered and consequently very difficult to leach out form. Only after sintering does the landfill take place or even further processing, for example as artificial Surcharge for road construction and as a surcharge for concrete.
Für ein derartiges Zusammenwirken muß die pulverför mige Asche oder die anderen Reststoffe zunächst briket tiert und danach thermisch behandelt werden. Diese thermi sche Behandlung erfolgt in der Regel in einem mit fossilen Brennstoffen beheizten Ofen. Dann besteht aber die Gefahr, daß ein nicht unwesentlicher Anteil der toxischen Bestand teile durch die Abgase ausgetragen wird, so daß er in die Umwelt gelangt.For such interaction, the powder ash or the other residues first briquette be treated and then thermally treated. This thermi The treatment is usually done with fossil Fuels heated furnace. Then there is a risk that a not insignificant proportion of the toxic stock parts is discharged through the exhaust gases, so that it in the Environment.
Aufgabe der Erfindung ist es daher, ein Verfahren zu schaffen, mit dem eine das spätere Auslaugen verhindernde Sinterung möglich ist, ohne daß Schadstoffe während der thermischen Behandlung in die Umgebung gelangen können.The object of the invention is therefore to provide a method with which one prevents later leaching Sintering is possible without pollutants during the thermal treatment can get into the environment.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß das pulverförmige Ausgangsmaterial zu Briketts kompaktiert und anschließend in einem Mikrowellenbett gesintert wird. The object is achieved in that the powdery starting material is compacted into briquettes and then sintered in a microwave bed.
Da ein Brennen in konventionellen, mit fossilen Brennstof fen beheizten Öfen entfällt, können die Briketts nicht in Kontakt mit strömenden Gasen kommen, so daß eine Verdamp fung der toxischen Bestandteile entfällt, zumindest aber minimalisiert wird.Because a burning in conventional, with fossil fuel If heated ovens are omitted, the briquettes cannot Coming into contact with flowing gases, causing an evaporator The toxic components are not used, at least however is minimized.
Nach einer zweckmäßigen Ausführung der Erfindung ist vorgesehen, daß dem Ausgangsmaterial eine Komponente zugemischt wird, die eine hohe Absorptionsfähigkeit für Mikrowellen aufweist. Dadurch wird eine schnelle und sichere thermische Behandlung erreicht und das Abgeben der toxischen Bestandteile erschwert.According to an expedient embodiment of the invention provided that the starting material has a component is admixed, which has a high absorbency for Has microwaves. This will make a quick and achieved safe thermal treatment and dispensing of the toxic components difficult.
Als besonders geeignet sieht die Erfindung Magnetit vor, das als rohes Eisenerz in ausreichenden Mengen zur Verfügung steht und erfindungsgemäß dem Ausgangsmaterial zugemischt werden kann.The invention sees magnetite as particularly suitable before that as raw iron ore in sufficient quantities for Is available and according to the starting material can be added.
Insgesamt gesehen steht damit ein Verfahren zur Verfügung, mit dem auch große Mengen industrieller Rest stoffe sicher so verarbeitet werden können, daß die darin enthaltenen toxischen Bestandteile anschließend nicht in die Umwelt entweichen können und das weder durch Regenwas ser oder Grundwasser noch durch vorbeiströmende Gase während der thermischen Behandlung.Seen as a whole, this is a procedure With which even large quantities of industrial rest substances can be processed safely so that the contained toxic components subsequently not in the environment can escape and that neither through rainwater water or groundwater due to gases flowing past during the thermal treatment.
