Beschreibung und Erläuterung zur Zusatz-PatentanmeldungDescription and explanation of the additional patent application
'Streckendämm-Material, vorzugsweise für den untertägigen Bergbau' Zusatz zu P 30 26 454.1 In der Hauptanmeldung wird die Herstellung von Streckendämm-Material beschrieben, das dadurch gekennzeichnet ist, daß man Rotschlamm, der als Abfall in der Aluminiumindustrie anfällt, mit dem nassen, nicht-gebrannten CaSO4 aus Rauchgasentschwefe lungsanlagen, vorzugsweise hinter Kraftwerken oder auch Müllverbrennungsanlagen, mischt, um dieses Gemisch als Streckendämm-Material zu verwenden.'Track insulation material, preferably for underground mining' Addition to P 30 26 454.1 In the main application, the production of line insulation material described, which is characterized in that one red mud, which is used as waste in the aluminum industry, with the wet, unburnt CaSO4 from flue gas desulphurisation plants, preferably behind power plants or waste incineration plants, mixes to use this mixture as a route insulation material.
Erfindungsgemäß wird erweitert vorgeschlagen, das Calciumchlorid, welches zwangsläufig bei der Waschung der Abgase aus Müllverbrennungsanlagen und/oder auch fossilen Kraftwerksanlagen anfällt und nur mit großem Aufwand beseitigt werden kann und in der Regel mit hohem Wärmeenergiebedarf als Salz ausgedampft werden muß, mit Rotschlamm aus der Aluminiumindustrie sowie mit dem Abfallprodukt CaSO4 aus Rauchgasentschwefelungsanlagen ungebrannt in einer flüssigen oder festen Konsistenz von vorzugsweise 20 - 30 % zu mischen, so daß für den Winter, auch bei Frostperioden, dieser Dammbaustoff a) gut dponierbar und b) transportabel ist und unter Tage mit dem Staubbinde- und Flammwidrig-Effekt durch das Calciumchlorid verarbeitet - d. h. gepumpt - oder zu einem Damm angeblasen werden kann.According to the invention it is proposed that the calcium chloride, which inevitably in the scrubbing of the exhaust gases from waste incineration plants and / or fossil power plants also arise and can only be removed with great effort can and usually has to be evaporated as salt with a high heat energy requirement, with red mud from the aluminum industry and with the waste product CaSO4 Flue gas desulphurisation systems unfired in a liquid or solid consistency of preferably 20 - 30% to be mixed, so that for the winter, even during periods of frost, this dam building material a) easy to position and b) transportable and Processed underground with the dust-binding and flame-retardant effect due to the calcium chloride - d. H. pumped - or blown to a dam.
Weiterhin wird erfindungsgemäß vorgeschlagen, ebenfalls zur Entsorgung von Eisen- und Hüttenwerken den dort anfallenden Staub, der aus Metalloxiden, Erdalkalien usw. besteht, zusätzlich mit zuzumischen und/oder anstelle von z. B. Rotschlamm zu verwenden.Furthermore, it is proposed according to the invention, likewise for disposal from iron and steel works the dust that accumulates there, that of metal oxides, alkaline earths etc. is to be added in addition to and / or instead of z. B. red mud to use.
Selbstverständlich ist die Erfindung nicht auf die vorstehend im einzelnen beschriebenen Formen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, Abfallprodukte aus der Rauchgasentschwefelung hinter Fossil-Kraftwerken und/oder Müllverbrennungsanlagen, bestehend aus CIS04 ungebrannt (CaS04 + 2H20), mit Rotschlamm aus der Aluminiumindustrie und/oder Abfallprodukten aus der Eisen- und Hüttenindustrie, wie Eisenstäube, Eisenoxide usw., zu mischen und zur Verbesserung der Staubbindung für das Einblasen des Dämm-Materials das Abfallprodukt aus der Rauchgasentschwefelungsanlage hinter Kraftwerken und/oder Müllverbrennungsanlagen, das als alciumchlorid bezeichnet werden kann und in einer Konsistenz von 20 - 25 % anfällt, einzumischen und zusätzlich insbesondere zur Herstellung von feuerfesten Streckendämmen Stäube aus der Ferosilicium- und/oder Siliciumherstellung sowie auch Bentonit zusätzlich einzumischen.Of course, the invention is not limited to the above in detail forms described, but numerous modifications are possible, However, without deviating from the basic idea, waste products from flue gas desulphurisation behind fossil power plants and / or waste incineration plants, consisting of CIS04 unfired (CaS04 + 2H20), with red mud from the aluminum industry and / or waste products from the iron and steel industry, such as iron dusts, iron oxides, etc. to mix and to improve the dust binding for the blowing in of the insulation material, the waste product from the flue gas desulphurization system behind power plants and / or waste incineration plants, which can be referred to as alcium chloride and in a consistency of 20 - 25% is to be mixed in and especially for production from refractory dams Dust from ferosilicon and / or silicon production and also bentonite to be mixed in.
Weiterhin wird erfindungsgemäß vorgeschlagen, daß bei gewollter, schneller Aushärtung diesen genannten Produkten Kalkhydrat und/ oder Weißfeinkalk zugemischt wird, um eine chemische Reaktion einzuleiten, die die Aushärtung beschleunigt.Furthermore, it is proposed according to the invention that when wanted, faster Hardening of these products mentioned hydrated lime and / or white fine lime admixed to initiate a chemical reaction that accelerates the hardening process.
