Abstract

Residual products from waste incineration systems are unsuitable for landfill sites, so that official regulations frequently require them to be stored on a special landfill site, which is very complicated. To avoid the difficulties associated with this, it is proposed according to the invention to provide the waste incineration with a dry chemisorption system for binding the pollutants from the flue gas, in which slaked lime is preferably used for the chemisorption and the reacted and partly unreacted slaked lime is mixed with the residual products comprising filter ash, boiler slag, with the addition of cement, or is mixed during transport in a mixer vehicle which is equipped with a mixer tank and serves for transport from the waste incinerator to the landfill site, and, at the landfill site, the solidification reaction is initiated according to the invention by the addition of water and calcium chloride and the material is transferred to the landfill site in pelletised or unpelletised form and in a form stable against leaching by water.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

"Verfahren zur Beseitigung von Rückstandsprodukten aus Müllverbrennungsanlagen" Es ist bekannt, daß Rückstandsprodukte aus Müllverbrennungsanlagen deponieunfreundlich sind."Procedure for the removal of residue products from waste incineration plants" It is known that residue products from waste incineration plants are unfriendly to landfills are.

Es gibt viele Untersuchungen, wie das Material deponiefest gemacht werden kann.There have been many studies of how the material was made landfill-proof can be.

Alle bekannten Untersuchungen und in der Literatur bekannten Versuche weisen recht komplizierte Verfahrenstechnologien auf.All known investigations and experiments known in the literature have quite complicated process technologies.

Vielfach endet die behördliche Auflage mit der Auflage einer Sonder-Deonie; das bedeutet, wasserundurchdringliche Abdichtungsflächen sind zu schaffen in Form von Verpressungen bzw. Abdichtungsarbeiten mittels Kunststoffe oder Konsolidierung der Begrenzungs flächen und des Untergrundes durch Zement-Wasserglas-Inåektionen usw.In many cases, the official requirement ends with the requirement of a special deonie; This means that waterproof sealing surfaces have to be created in the form of grouting or sealing work using plastics or consolidation the limit surfaces and the subsurface by means of cement-water glass inåections etc.

Um alle diese Nachteile zu beseitigen, wird erfindungs gemäß vorgeschlagen, die Müllverbrennung so aufzubauen, daß die in den Rauchgasen enthaltenen Schadstoffe wie SO4 , SOf , HC1, NOx usw. mit einer trockenen Chemisorption entsorgt werden, wobei die Rückstandsprodukte, bestehend aus den Chemisorptionsmitteln, die z.B. mit Kalkhydrat zu CaSO4 , CaSO3 , CaC12 und ähnlichen Produkten reagiert und gewandelt wurden, mit Elektro-oder Filterasche grundsätzlich mit Zement und der Kesselschlacke gemischt bzw zweckdienlicherweise einem Fahrzeug übergeben werden, das als Mischer ausgebildet ist, um das Trockenprodukt auf der Fahrt vom Müllverbrennungsort zur Deponiestelle zu mischen, und daß an der Deponiestelle unter gleichzeitigem Mischen Wasser zugegeben wird und zur Einleitung der Reaktion, äe nach Bedarf als Beschleunigungsmittel zusätzlich Calciumchlorid zugegeben werden kann, das z.B. auch aus der Rauchgasreinigung der Müllverbrennungs-Gasreinigung herrührt. Die so gemischte Masse kann problemlos auf einer Deponie gelagert werden.In order to eliminate all these disadvantages, it is proposed according to the invention, to build up the waste incineration so that the pollutants contained in the flue gases such as SO4, SOf, HC1, NOx etc. are disposed of with dry chemisorption, the residue products consisting of the chemisorbents e.g. Reacts and converts with hydrated lime to CaSO4, CaSO3, CaC12 and similar products were, with electrical or filter ash, basically with cement and the boiler slag mixed or expediently transferred to a vehicle, which is used as a mixer is designed to the dry product on the journey from the waste incineration site to To mix landfill, and that at the landfill with simultaneous mixing Water is added and to initiate the reaction as an accelerator as needed Additionally Calcium chloride can be added, which e.g. also consists of the flue gas cleaning comes from the waste incineration gas cleaning. The so mixed one Mass can easily be stored in a landfill.
