Abstract

Process for ceramicising spoil from mining establishments. It is known thermally to ceramise spoil arising in underground operation, in order to utilise it for certain fields of application. For this purpose, a process is proposed according to the invention in which the washing and/or crushing spoil is used, as a result of admixing domestic refuse and waste materials, as energy carrier and availability improver against caking in the thermal ceramicising field. The availability of the washing and/or crushing spoil as energy carrier and product improver is increased by admixing domestic refuse and waste materials and, by adding chemisorption agents, a further immobilisation of pollutants (HCl, HF, SO2 and the like) is achieved.

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

"Verfahren zur Verwendung von Bergen aus dem Kohlebergbau" Es ist bekannt, Berge aus dem Bergbau Untertage-Bereich in Form von Brech- und/oder Waschbergen entweder auf zuhalden oder teilweise auch als Unterbau für den Straßen- und Wegebau zu nutzen."Method of using mountains from coal mining" It is known, mountains from underground mining in the form of crushing and / or washing mountains either on heaps or partly as a substructure for road and path construction to use.

Das Finden von Grundstücken für die Aufhaldung wird in Zukunft immer schwieriger.Finding plots for heaping up will always be in the future more difficult.

Grundstückskonzeptionen außerhalb des Ruhrreviers bedeuten hohe Frachtkosten und somit eine nicht erwünschte Grundlast to/verwertbarer Kohleförderung.Land concepts outside the Ruhr area mean high freight costs and thus an undesirable base load to / usable coal production.

Es ist bekannt, Untertage-Berge thermisch zu keramisieren, um sie für bestimmte Anwendungsbereiche zu nutzen.It is known to thermally ceramize underground mountains around them for certain areas of application to use.

Es sind die unterschiedlichsten Brennofenkonzeptionen bekannt, in denen die Berge entsprechend gebrannt werden.A wide variety of kiln designs are known in which the mountains are burned accordingly.

Das Brennen muß jedoch unter Zugabe von Energie, vorzugsweise von Kohle, Koks, Oel, Gas oder dergleichen ermöglicht werden.The burning must, however, with the addition of energy, preferably of Coal, coke, oil, gas or the like are made possible.

Vielfach wird das Keramisieren dadurch erschwert, daß die nicht homogen zusammengesetzten Berge thermisch zusammenbacken und den Prozeßablauf'in der Verfügbarkeit und Qualität des Produktes stark negativ beeinflussen.In many cases, ceramizing is made more difficult because it is not homogeneous thermally bake composite mountains together and the process flow'in the availability and quality of the product have a strong negative impact.

Erfindungsgemäß wird daher vorgeschlagen, ein Verfahren zu verwenden, bei dem a) die notwendige zusätzliche Energie zur Keramisierung der Berge aus Zusatz von brennbarem Abfall herstammt, wobei der Abfall gleichzeitig das störende Verbacken der Berge miteinander unterbindet und somit die Verfügbarkeit und die eualitat der Produktbildung des Verfahrens -Keramisieren von Bergen - begünstigt.According to the invention it is therefore proposed to use a method in which a) the necessary additional energy to ceramize the mountains from additive originates from combustible waste, the waste simultaneously causing the annoying caking the mountains with each other prevents and thus the availability and the quality of the product formation of the process - ceramizing mountains - favors.

Dieses wird erfindungsgemäß dadurch erzielt, indem man einen Schacht- oder Drehofen in bekannter Weise verwendet und das keramisierende Berge gemisch mit Müll vermischt und im gewünschten Temperaturbereich vorzugsweise bei 950 OC keramisiert.This is achieved according to the invention by a shaft or rotary kiln used in a known manner and the ceramizing mountains mixed mixed with garbage and in the desired temperature range preferably at 950 OC ceramized.

Vorzugsweise wird der Lüll sortiert und wunschgerecht für die entsprechende Aufgabenstellung zerkleinert.Preferably, the Lüll is sorted and as desired for the corresponding Task shredded.

Die heißen Abgase können erfindungsgemäß gleichzeitig zur Vortrocknung der einzusetzenden Berge, des Mülls und/oder des Berge-Müllgemisches dienen.According to the invention, the hot exhaust gases can be used for predrying at the same time the mountains to be used, the garbage and / or the mountain-garbage mixture.

Außer Hausmüll kennen auch noch nachträglich aufgeführte Abfall- und schlecht verwertbare Stoffe als zusätzliche Energielieferer für die Bergekeramisierung eingesetzt werden: a) Schlammkohle b) Flotationskonzentrat c) Flotationsberge d) Dickteere e) Abfalloele f) Hobelspäne, Sägemehl, Abfallholz g) Bergbauabfälle usw..In addition to household waste, we also know those listed subsequently Waste- and poorly usable materials as additional energy suppliers for mountain ceramization the following are used: a) sludge coal b) flotation concentrate c) flotation mountains d) Thicker e) waste oil f) wood shavings, sawdust, waste wood g) mining waste etc ..

Um die in der Körnung und in der Zusammensetzung sehr heterogen zusammengesetzten Kohlenberge in qualitativ gutem und gleichmäßigem Zustand, d.h.Around the very heterogeneous in terms of grain and composition Coal mountains in a qualitatively good and uniform condition, i.e.

einheitlicher Keramisierung und Körnung herstellen zu können, wird erfindungsgemäß vorgeschlagen, die zu keramisierenden Kohleberge über eine Vorklassierung in Kornklassen zu trennen und die einzelnen Kornklassen separat zu keramisieren, wobei mehrere fen nebeneinander stehen und jeder Ofen für eine bestimmte Korngröße vorgesehen ist.to be able to produce uniform ceramization and grain size proposed according to the invention, the coal mountains to be ceramized via a pre-classification to be separated into grain classes and the individual Grain classes separately to ceramize, with several ovens standing next to each other and each oven for one certain grain size is provided.

Es ist vorteilhaft, das unbehandelte Gut in drei oder mehrere Kornklassen zu zerlegen, wobei die maximale orneröße im Durchschnitt 57 - 63 mm überschreiten sollte und im Minimum «: 10 mm betragen sollte.It is advantageous to divide the untreated material into three or more grain classes to be dismantled, whereby the maximum front size on average exceeds 57 - 63 mm should and at least «: should be 10 mm.

Das Korn z 10 mm kann auch gleichmäßig auf alle Korngrößen verteilt werden, um Energie zu sparen, da es sicherlich einen sehr hohen Kohleanteil besitzt.The grain z 10 mm can also be evenly distributed over all grain sizes to save energy, as it certainly has a very high carbon content.

Weiterhin wird erfindungsgemäß vorgeschlagen, daß die Abwärme aus diesem Prozeß energetisch für z.B.Furthermore, it is proposed according to the invention that the waste heat from this process energetically for e.g.

eine Fernwärmeversorgung genutzt werden kann.a district heating supply can be used.

Auf der beiliegenden Zeichnung ist dargestellt: mit (1) z.B. der Drehtrommel-Keramisierungsofen, mit (2) die Zuführung der Berge, mit dem Pfeil (3) die Zuführung des vorzugsweise vorsortierten Mülls, mit (4) der Austrag der keramisierten Berge und des gebildeten Ascheproduktes aus dem Müll, mit (5) der Abgaskamin, der die heißen Abgase einer Vorerhitzungskammer für Müll und/oder Berge (6) zuführt, mit (7) die Abgase, die einer Gasreinigung aus Umweltschutzgründen zugeführt werden können.The attached drawing shows: with (1) e.g. the rotary drum ceramizing furnace, with (2) the supply of the mountains, with the arrow (3) the supply of the preferably pre-sorted garbage, with (4) the discharge the ceramized mountains and the ash product formed from the garbage, with (5) the exhaust chimney, which the hot exhaust gases of a preheating chamber for garbage and / or Mountains (6) supplies, with (7) the exhaust gases, which are a gas cleaning for environmental reasons can be fed.

Das Gemisch aus Bergen und Müll kann selbstverstündlich durch Zumischung von Chemisorptionsmitteln wie CaO, Sole, Rotschlamm oder dergleichen zur Bindung von Schadstoffen bereits schon prozeßtechnisch umweltfreundlich gestaltet werden.The mixture of mountains and garbage can of course be mixed in of chemisorbents such as CaO, brine, red mud or the like for binding of pollutants are already made environmentally friendly in terms of process technology.

Selbstverständlich ist die Erfindung hier nicht auf die vorstehend im einzelnen beschriebenen oder dargestellten Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, das Keramisieren von Bergbaubergen so herzustellen, daß es mit hoher Verfügbarkeit unter Verwendung von Abfallstoffen und Hausmüll als Zusatzbrennstoff und Chemisorptionsmittel als Beimischung für die Schadstoffbindung erfindungsgemäß Anwendung findet.Of course, the invention does not apply here the the forms of training described or shown in detail above are limited, instead, numerous modifications are possible without, however, from the basic idea to deviate the ceramization of mining mountains so that it can be done with high Availability using waste materials and household waste as additional fuel and chemisorbents as an admixture for binding pollutants according to the invention Applies.
