Abstract

The main application P 3209266.0 relates to a process in which washed dirt and/or milling dirt, by admixture of refuse and waste, is utilised as fuel and availability improver against caking in the thermal, ceramic formation area. In a further development of this process, it is proposed according to the invention to add alkaline earth metal compounds to the ceramic formation process. The alkaline earth metal compounds are composed of residual products of flue gas desulphurisation plants. This addition is used for the ceramic formation process for particle sizes below 10 mm.

Description

Beschreibung und Erläuterung zur ZusatzpatentanmeldungDescription and explanation of the additional patent application

"Verfahren zur Verwendung von Bergen aus dem Kohlebergbau unter Zuführung von Abfallprodukten aus der Rauchgasreinigung" Zusatz zu P 32 09 266.0 In der Eauptanmeldung wird ein Verfahren beschrieben, das Keramisieren von Bergbaubergen so herzustellen, daß es mit hoher Verfügbarkeit unter Verwendung von Abfallstoffen, vorzugsweise Hausmüll als Zusatzbrennstoff und Lockerungsmittel, und Chemisorptionsmitteln als Beimischung für die Schadstoffbindung Anwendung findet, wobei vorzugsweise das Gesamtverfahren in mehreren Körnungsstufen aufgebaut ist."Method of using piles from coal mining under feed of waste products from flue gas cleaning "Addition to P 32 09 266.0 in the main application a process is described to produce the ceramization of mining mountains in such a way that that it is highly available using waste materials, preferably Household waste as additional fuel and loosening agent, and chemisorbents as Admixture for binding pollutants is used, preferably the overall process is built up in several grain sizes.

Der weitere erfindungsgemäße Gedanke liegt im folgenden begründet: Das Abfallprodukt der Kohleförderung sind Brech-und/oder Waschberge.The further idea according to the invention is based on the following: That Waste products from coal mining are piles of crushing and / or washing mountains.

Das Abfallprodukt bei der Verwendung von Kohle in Kraftwerken ist für rauchgasentschwefelte Kraftwerke 1. Filterasche und 2. gibt es Abfallprodukte aus eingesetzten Erdalkaliverbindungen, wie Kalkstein usw. und den bei der Schwefelbildung daraus entstehenden Naßgips -ungebrannt Es ist bekannt, Baustoffe durch Zusatzstoffe wie Erdalkaliverbindungen zu verbessern.The waste product from using coal in power plants is for flue gas desulphurized power plants 1. fly ash and 2. there are waste products from the alkaline earth compounds used, such as limestone, etc. and those involved in the formation of sulfur The resulting wet gypsum - unburned It is known to add additives to building materials how to improve alkaline earth compounds.

Hierdurch wird insbesondere das hydraulische Abbindeverhalten gefördert.This particularly promotes the hydraulic setting behavior.

Erfindungsgeinäß wird daher vorgeschlagen, entsprechend der Hauptanmeldung dem Keramisierungsprozeß die nassen, ungebrannten Erdalkaliverbindungen vorzugsweise im Endprodukt der Rauchgasentschwefelungstechnologie wie Gips, den Wasch- und/oder Brechbergen zuzuführen, wobei hier zwangsläufig erfindungsgemäß durch die überschüssige Wärme z.B. Beta Halbhydrat entsteht, das sich zwangsläufig mit dem Eeramisierungsprozeß bildet und einen wunschgerechten Baustoff -entsprechend der Beimischung - darstellt.According to the invention, it is therefore proposed in accordance with the main application the ceramization process the wet, unfired alkaline earth compounds preferably in the end product of flue gas desulfurization technology such as gypsum, the To supply washing and / or crushing mountains, inevitably according to the invention here due to the excess heat e.g. beta hemihydrate is created, which inevitably develops with the Eeramisierungsprocess and forms a desired building material - accordingly the admixture - represents.

Durch verschiedene Verfahrensschritte können natürlich auch Eristallstrukturen des Gipses im Naß- und oder Trockenzustand - je nach dem Verfahrensprozeß zur Rauchgasentschwefelung - der keramisierten Masse zugesetzt werden, so daß nicht nur Beta-Halbhydratkristalle, sondern auch alle anderen Eristallformen bis einschließlich dem Alpha-Halbhydrat zur Verwendung kommen können.Of course, crystalline structures can also be created through various process steps of gypsum in the wet and or dry state - depending on the process for flue gas desulphurisation - are added to the ceramized mass, so that not only beta hemihydrate crystals, but also all other crystalline forms up to and including the alpha hemihydrate can be used.

Weiterhin - je nach dem Verwendungszweck - wird erfindungsgemäß vorgeschlagen, diesem genannten erfindungsgemäßen Keramisierungsprozeß Filterasche aus dem Entstaubungsprozeß hinter Kohlekraftwerken oder Müllverbrennungsanlagen zuzuführen, so daß Baustoffe mit den Eigenschaften des Klinkers oder mit ähnlichen gewollten Eigenschaften herstellbar sind.Furthermore - depending on the intended use - it is proposed according to the invention, this ceramization process according to the invention mentioned filter ash from the dedusting process Behind To supply coal-fired power plants or waste incineration plants, so that building materials with the Properties of the clinker or with similar desired properties can be produced are.
