Abstract
Building material for underground use is produced from residues from Ti extraction and from Zn extraction by the Jarosite process, which are mixed with E-filter ashes and concentrated salts CaCl2 X 2H2O/NaCl from refuse incineration plants. An exothermic reaction is initiated, the mixture being heated to 120-180 deg.C, pref. 180 deg.C, and a dry product is formed by water evapn. Binders e.g. cement, gypsum, lime, etc. are added. ADVANTAGE - Eluate-resistant, PCCD and PCCF-free material, which does not generate H2.
Description
Bei der Herstellung von Baustoffen für den Unterta gebergbau aus Eisen-II-sulfaten mit 20-35% freier Schwefelsäure aus der Titanoxidgewinnung mittels E-Filteraschen nach der P-Anmeldung P 39 37 312.6 wurde weiterhin untersucht, für die Neutralisation reine MVA-Filterstäube einzusetzen.In the production of building materials for the Unterta mining of iron-II-sulfates with 20-35% free sulfuric acid from titanium oxide production using E-filter ash after P-registration P 39 37 312.6 was also examined for Neutralization to use pure MVA filter dust.
Da die Filterstäube aus Müllverbrennungsanlagen leicht mit PCCD und PCCF belastet sind und außer dem mehr oder weniger Aluminium beinhalten, neigen diese Filterstäube bei der Anfeuchtung mit Wasser auch zur Wasserstoffbildung.Because the filter dust from waste incineration plants are lightly loaded with PCCD and PCCF and except which contain more or less aluminum this filter dust when moistened with water also for hydrogen formation.
Bei Einsatz dieser MVA-Filterstäube hat sich über raschenderweise gezeigt, daß bei Einhaltung eines bestimmten pH-Wertes und einer bestimmten Reak tionstemperatur im neutralisierten Endprodukt die PCCD- und PCCF-Anteile zerstört werden und eine Wasserstoffbildung kaum noch meßbar ist. When using this MVA filter dust has over surprisingly shown that if a certain pH and a certain reak tion temperature in the neutralized end product PCCD and PCCF parts are destroyed and one Hydrogen formation is hardly measurable.
Der pH-Wert der Neutralisationsmassen sollte zwischen pH 6,0-8,5 liegen.The pH of the neutralizing masses should are between pH 6.0-8.5.
Die Reaktionstemperatur sollte 120°C-180°C betragen, vorzugsweise 180°C.The reaction temperature should be 120 ° C-180 ° C amount, preferably 180 ° C.
Dazu kann es erforderlich sein, daß den MVA- Filterstäuben 10%-20% Weißfeinkalk CCaO, Kalk steinmehl (CaCO3) oder Wirbelschichtaschen zuge setzt werden, um die Neutralisationstemperatur max. 180°C zu erreichen.For this it may be necessary to add 10% -20% white fine lime CCaO, limestone powder (CaCO 3 ) or fluidized bed ash to the MVA filter dust in order to max. To reach 180 ° C.
Durch dieses Neutralisationsverfahren entsteht durch Wasserverdampfung ein Trockenprodukt, das unter Zusatz von Bindemitteln, wie Zementen, Gip sen, Kalk und/oder org. Harzsystemen, zu einem eluatfesten, PCCD- und PCCF-freien und keinen wasserstoffbildenden Baustoff vorzugsweise für den Untertagebergbau verarbeitet werden kann.This neutralization process creates by evaporation of water a dry product that with the addition of binders such as cements, gypsum sen, lime and / or org. Resin systems, into one eluate-proof, PCCD and PCCF-free and none hydrogen-building material preferably for the Underground mining can be processed.
Durch dieses erfindungsgemäße Verfahren entsteht aus belasteten Abfallstoffen ein Wirtschaftsgut, das entsprechend der Beschreibung im Bergbau, für die Landrückgewinnung oder auch für den Straßen- und Wegebau sowie Küstenlandbefestigungen einge setzt werden kann.This method according to the invention results an economic good from polluted waste materials, that according to the description in mining, for land reclamation or for road and road construction as well as coastal land fortifications can be set.
