Description
Die Erfindung betrifft ein Verfahren zum Aufbereiten eisenhaltigen Ölschlamms für die Weiterverarbeitung. Insbesondere in Walzwerken fallen beim Walzen große Mengen von eisenhaltigen Ölschlammen an, deren Lagerung oder Wiederverwendung heute noch ein großes Umweltproblem darstellt. Auch in Klaranlagen, insbesondere solchen, die Stahlwerken oder metall-verarbeitenden Betrieben od. dgl. zugeordnet sind, fallen größere Mengen eisen- und ölhaltiger Klärschlamm an.The invention relates to a method for processing ferrous oil sludge for further processing. Particularly in rolling mills, large amounts of iron-containing oil sludge are produced during rolling, and their storage or reuse is still a major environmental problem today. Also in clear plants, especially those that are associated with steel mills or metal processing plants or the like, larger quantities of iron and oil-containing sewage sludge are produced.
Solche Schlämme können bis zu 50% Eisen enthalten. Die darin enthaltenen Eisenpartikol weisen eine so geringe Größe auf, daß ein Trennen des Eisens vom Öl und anderen Flüssigkeiten sehr schwierig bis unmöglich ist.Such sludges can contain up to 50% iron. The Eisenpartikol contained therein have such a small size that a separation of the iron from the oil and other liquids is very difficult to impossible.
Wird eisenhaltiger Ölschlamm getrocknet., so kann das abgetrennte Eisen(-pulver) darüber hinaus aufgrund seiner geringen Partikelgröße als loses Material nicht wieder verhüttet werden.If iron-containing oil sludge is dried, the separated iron (powder) can not be re-smelted because of its small particle size as a loose material.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren zum Aufbereiten eisenhaltigen Ölschlamms für die Weiterverarbeitung zu schaffen, bei dem dieser wiederverwendet werden kann.The invention is therefore an object of the invention to provide a method for processing ferrous oil sludge for further processing, in which this can be reused.
Diese Aufgabe wird durch das im Anspruch 1 beschriebene Verfahren gelöst. Bei diesem Verfahren zum Aufbereiten eisenhaltigen Ölschlammsfür die Weiterverarbeitung wird der Ölschlamm zusammen mit Kohle und Kunststoff, insbesondere Kunststoffabfällen und/oder klebrigen, insbesondere organischen Schlämmen, in einer Schneckenpresse gemischt, geknetet und gepreßt und ein abgebundendes, festes weiterverarbeitbares Produkt extrudiert.This object is achieved by the method described in claim 1. In this method of processing ferrous oil sludge for further processing, the oil sludge is mixed, kneaded and pressed together with coal and plastic, in particular waste plastics and / or sticky, in particular organic, slurries in a screw press, and extrudes a tempering, solid, further processable product.
Beim Pressen verdampfen Flüssigkeiten mit relativ niedrigem Siedepunkt, wie Wasser, welches dadurch aus dem Feststoff-Flüssigkeits-Gemisch entfernt werden kann.During pressing, liquids of relatively low boiling point, such as water, evaporate, which can thereby be removed from the solid-liquid mixture.
Die Kohle kann in Form von Koksgrus dem Gemisch zugegeben werden, der dabei gleichzeitig einer Wiederverwendung zugeführt werden kann.The coal can be added to the mixture in the form of coke breeze, which can be recycled at the same time.
Zweckmäßigerweise wird der feste Kunststoff, z. B. Kunststoffabfall gegebenenfalls vor dem Mischen mit den anderen Bestandteilen vorzerkleinert, so daß sich in der Schneckenpresse eine innige Vermischung ergibt. Dabei kann der Kunststoff z. B. in granulierter Form dem Gemisch beigegeben werden. Das Granulat kann einen Durchmesser von 10mm bis 40mm aufweisen. So kann z. B. Folienafall eine Fläche von 2 mm x 2 mm aufweisen. Dadurch erhält man eine gleichmäßige Mischung in dem aus der Schneckenpresse austretenden Material.Conveniently, the solid plastic, z. B. plastic waste optionally pre-comminuted before mixing with the other ingredients, so that there is an intimate mixing in the screw press. In this case, the plastic z. B. be added in granulated form to the mixture. The granules can have a diameter of 10mm to 40mm. So z. B. foil fall have an area of 2 mm x 2 mm. This gives a uniform mixture in the material emerging from the screw extruder.
Gemäß einer bevorzugten Ausführungsform des Verfahrens weist das in die Schneckenpresse einzugebende Gemisch folgende Bestandteile auf: 50% bis 60% Ölschlamm, 30% bis 35% Kohle und 5% bis 10% KunststoffAccording to a preferred embodiment of the method, the mixture to be introduced into the screw extruder comprises the following components: 50% to 60% oil sludge, 30% to 35% coal and 5% to 10% plastic
Der Ölschlamm kann dabei einen Eisenanteil von etwa 50% aufweisen. The oil sludge can have an iron content of about 50%.
beigemischt werden. So können z. B. schadstoffenthaltende Flüssigkeiten in die Schneckenpresse eingegeben werden. Eskönnen auch Kunststoffabfälle und organischen Schlämme gemischt werden. Durch die große Wärme in der Schneckenpresseverdampft die Flüssigkeit, insbesondere Wasser. Die verdampfende Flüssigkeit kann, insbesondere, wann auch sie schädlich ist,beim Entweichen aus der Schneckenpresse aufgefangen und kondensiert werden. Die Feststoffbestandteile werden in dasbe mixed. So z. B. pollutant-containing liquids are entered into the screw press. It is also possible to mix plastic waste and organic sludge. Due to the great heat in the screw press, the liquid evaporates, especially water. The vaporizing liquid can, in particular, when it is harmful, be caught and condensed on escaping from the screw press. The solid components are in the

Since very high temperatures are required during smelting, it is therefore also possible with this method to add otherwise difficult to recycle or destroy chemical waste with the mixture into the screw press since these are processed during later smelting.
