Abstract

Converting halogenated, cyclic hydrocarbons into inorganic halide cpds. comprises treating alkaline material, e.g., filter dust from incinerators or absorbers used for air purificn. in waste incinerators with glycol to dissolve organically bound halogens and convert them into inorganic cpds.. Waterglass is then added to the treated material to improve agglomeration and simultaneously increase the rate of reaction. USE - Dust and/or absorption media can be recycled or safely disposed of, due to the removal of toxic cpds. such as furans and dioxin

Description

Es ist bekannt, daß hinter Müllverbrennungsanlagen in den Elektro- und/oder Gewebefiltern Stäube gefunden werden, die mit Dioxinen, Furanen und Schwermetallen belastet sind.It is known that behind waste incineration plants in the electrical and / or Fabric filters can be found dusts containing dioxins, Furans and heavy metals are contaminated.

Weiterhin werden in neuerer Zeit, um der TA-Luft gerecht zu werden, vor den eigentlichen Filtern Kontaktstrecken oder ein Kontaktreaktor eingebaut, die mit Absorptionsmitteln beaufschlagt werden, die bevorzugt aus alkalischen Mitteln und A-Kohlen, Koks, Braunkohle oder Braunkohlenkoks vermischt sind.Furthermore, in recent times, in order to do justice to TA-Luft be, before the actual filters contact lines or a Contact reactor installed, which is loaded with absorbents which are preferably made of alkaline agents and A-coals, coke, Lignite or lignite coke are mixed.

Unsere Aufgabenstellung ist es, diese Stäube und/oder Absorptions­ medien wiederverwendbar zu gestalten oder aber deponiefähig zu entgiften.Our task is to remove these dusts and / or absorption make media reusable or landfillable detoxify.

Es wurde gefunden, daß bei der vorhandenen hinreichenden Alkalität durch Zugabe von Glykol eine Reaktion verursacht wird, bei der das organisch gebundene Halogen aus seiner Verbindung gelöst und in eine anorganische Verbindung überführt wird.It was found that with the presence of sufficient alkalinity by adding glycol, a reaction is caused in which the organically bound halogen dissolved from its compound and in an inorganic compound is transferred.

Weiterhin wird erfindungsgemäß vorgeschlagen, daß nach dieser Reaktion Wasserglas als weiteres alkalisches Reagenz und Agglomerationsmittel den Materialien zugegeben wird, um eine Agglomeration und gleichzeitig die erforderliche Alkalität zur besseren Reaktion zu gewährleisten. Furthermore, the invention proposes that after this Reaction water glass as another alkaline reagent and Agglomerating agent is added to the materials to make a Agglomeration and at the same time the required alkalinity for to ensure better response.  

Es ist gewünscht, daß Dioxine und Furane gewandelt werden und die Feinstäube durch Agglomeration in der gesamten Materialkette miteingebunden werden, um den Vorzug "Teilchen größer 10 µm" zu erzielen, die bei der Verarbeitung als Baustoff keine Lungen­ gängigkeit besitzen.It is desired that dioxins and furans be converted and that Fine dust due to agglomeration in the entire material chain be included to give preference to "particles larger than 10 µm" achieve that when processing as a building material no lungs possess commonality.
