Abstract

Werkwijze voor het smelten van industriële reststoffen. Industriële milieu-onvriendelijke reststoffen zoals vliegassen van afvalverbrandingsinstallaties, straalgrit, zuiveringsslib of verontreinigde grond worden eventueel na toevoeging van toeslagstoffen zodanig gesmolten, dat een milieu-onschadelijk product wordt verkregen. Het milieu-onschadelijke product kan als zodanig bruikbaar zijn of dienen als grondstof van de productie van een goede cement. Het smelten vindt plaats in een electrische smeltoven bij 1.600 graden C, eventueel na voorverwarmen tot 1.000 graden C. De milieu-onvriendelijke stoffen ontwijken tijdens dit proces en worden op bekende wijze gevangen. Aan het milieu-onvriendelijke materiaal worden zodanige toeslagstoffen toegevoegd, dat het verkregen mengsel bij een temperatuur kan worden gesmolten, die 200 graden C tot 400 graden C lager is dan de temperatuur bij het hierboven beschreven smeltproces. De producten van deze tweede smelt wordt volledig verglaasd en kunnen zonder gevaar voor het milieu worden opgeslagen, omdat deze verglaasde milieu-onvriendelijke producten nagenoeg niet uitloogbaar zijn.Process for melting industrial residues. Industrial environmentally unfriendly residues such as fly ash from waste incineration plants, blasting grit, sewage sludge or contaminated soil are possibly melted after adding additives in such a way that an environmentally harmless product is obtained. The environmentally harmless product can be used as such or serve as raw material for the production of a good cement. Melting takes place in an electric melting furnace at 1,600 degrees C, possibly after preheating to 1,000 degrees C. The environmentally unfriendly substances escape during this process and are caught in a known manner. Additives are added to the environmentally unfriendly material such that the resulting mixture can be melted at a temperature that is 200 degrees C to 400 degrees C lower than the temperature in the melting process described above. The products of this second melt are completely vitrified and can be stored without danger to the environment, because these vitrified environmentally unfriendly products are virtually non-leachable.
