Abstract

In a process for treating oiled, water-drenched, iron-containing starting materials which arise as washed product such as mill scale in industrial processes - in particular as waste pieces from forming processes - the oiled and water-drenched, iron-containing starting materials are thermally contact-dried and the adhering oil is brought to ignition temperature. In addition, the oil is ignited or coked under a reducing atmosphere and a sinterable petroleum (oil) coke is produced.

Description

Die Erfindung betrifft ein Verfahren zum Aufbereiten von verölten, mit Wasser beaufschlagten, eisenhaltigen Einsatz­ materialien, die - wie Walzenzunder - als Waschgut bei industriellen Prozessen, insbesondere als Abfallteile bei Verformungsvorgängen anfallen.The invention relates to a method for processing oiled, water-loaded, iron-containing insert materials that - like mill scale - are used as laundry industrial processes, especially as waste parts Deformation processes occur.

Zum Kühlen von großen, schnellaufenden Walzengerüsten wer­ den deren Walzen mit emulgierten Schmier- und Kühlmitteln überflutet. Das Öl gelangt in den während des Walzvorganges entstehenden Walzenzunder, der - bis zu etwa 20% mit Öl­ anteil belastet - nicht mehr einsetzbar ist.For cooling large, high-speed roll stands their rollers with emulsified lubricants and coolants flooded. The oil gets into the during the rolling process emerging mill scale, which - up to about 20% with oil proportion charged - can no longer be used.

Durch das unvollkommene Verbrennen des Öles verkleben die Tuchfilter, und die Elektrofilter werden durch die entste­ henden Kantenstoffbrücken kurzgeschlossen, was zu Filter­ bränden bzw. zu Filterexplosionen führt.Due to the imperfect burning of the oil, they stick together Cloth filter, and the electrostatic precipitator are through the first existing edging bridges shorted out, leading to filters fires or leads to filter explosions.

Aus den genannten Gründen ist bereits vorgeschlagen worden, den Walzenzunder vor seinem Einsatz zu entölen, wozu es nach dem Stand der Technik die folgenden Methoden gibt.For the reasons mentioned, it has already been proposed to de-oil the mill scale before use, what for according to the prior art there are the following methods.

Man vermischt den verölten Walzenzunder so mit unveröltem Walzenzunder, daß der Gesamtanteil an Öl unter das schädli­ che Maß absinkt. Da eine echte Durchmischung von ölhaltigem mit nicht ölhaltigem Zunder kaum darstellbar ist, kommt es bei diesem Verfahren immer wieder zu Ölnestern und damit zu den oben bereits geschilderten Mängeln. You mix the oily mill scale with unoiled oil Roller mill that the total amount of oil under the harmful dimension drops. Because a real mix of oily it can hardly be produced with non-oily scale, it happens with this process again and again to oil pockets and thus the shortcomings already described above.  

Der ölhaltige Walzenzunder kann auch u. a. in eine nachge­ schaltete Koksbatterie gegeben werden. Durch die Anwesen­ heit von Eisen wird die sich bildende Schwefelsäure derart aggressiv, daß die mit ihr in Berührung kommenden Rohrsy­ steme kurzfristig zerfressen werden. Dies führt dazu, daß Hersteller von Kokereianlagen dann jegliche Garantie für letztere ablehnen, wenn der Einsatz von veröltem Walzenzun­ der vorgesehen ist.The oily mill scale can also u. a. in a subsequent switched coke battery are given. Through the estate As a result of iron, the sulfuric acid that forms becomes this way aggressive that the Rohrsy be eaten at short notice. This leads to Manufacturers of coke oven plants then provide any guarantee for reject the latter if the use of oily roller which is provided.

Probleme ergeben sich auch beim Reinigen von Metallspänen, insbesondere von Aluminiumspänen, die z. B. während eines spanabhebenden Formverfahrens mit Maschinenöl, ölhaltigem Kühlmittel od. dgl. benetzt worden sind. Es ist bekannt, Me­ tallspäne in einer Flüssigkeit zu waschen. Wäscht man etwa Aluminiumspäne in einer Lauge, wird durch Reaktion H2 frei, wobei eine große Menge von Schaum entsteht und sich Knall­ gas bildet.Problems also arise when cleaning metal chips, in particular of aluminum chips, the z. B. during a cutting molding process with machine oil, oil-containing Coolant or the like have been wetted. It is known to me Wash tall chips in a liquid. You can wash it Aluminum chips in a lye, is released by reaction H2, which creates a large amount of foam and bangs gas forms.

Angesichts dieser Gegebenheiten hat sich der Erfinder das Ziel gesetzt, ein Verfahren der eingangs erwähnten Art so zu gestalten, daß ein Entölen des industriellen Waschgutes, insbesondere des Walzenzunders, problemlos möglich wird.In view of these circumstances, the inventor did it Set the goal of a method of the type mentioned above to ensure that the industrial laundry is de-oiled, especially the mill scale, is easily possible.

Zur Lösung dieser Aufgabe führt die Lehre nach dem Pa­ tentanspruch 1. Besondere Weiterbildungen der Erfindung sind in den Unteransprüchen wiedergegeben.The teaching according to Pa claim 1. Special developments of the invention are reproduced in the subclaims.

Erfindungsgemäß werden die verölten und mit Wasser beauf­ schlagten, eisenhaltigen Materialien thermisch in einem Kontakttrockner getrocknet, das anhaftende Öl wird auf Zündtemperatur gebracht und bei reduzierender Atmosphäre gezündet bzw. verkokt. Nach diesem Verfahrensschritt kann das eisenhaltige Material mit dem verkokten Öl einer Sin­ teranlage zugeführt werden; es entsteht also insgesamt ein sinterbares Petrolkoks aus dem eisenhaltigen Material und seinem Öl, welches ohne weiteres in einer Sinteranlage - unter Einsparung von Kohle bzw. Koks - gesintert zu werden vermag.According to the oiled and water struck, ferrous materials thermally in one Contact dryer dried, the adhering oil is on Ignition temperature brought and in a reducing atmosphere ignited or coked. After this step, you can the ferrous material with the coked oil of a sin ter plant are fed; so it arises altogether sinterable petroleum coke made of the ferrous material and his oil, which is easily in a sinter plant  - to be sintered while saving coal or coke can

Dank des hierzu benutzten, mit Thermoöl betriebenen Kon­ takttrockners entsteht der nachfolgend beschriebene Vor­ gang.Thanks to the used Kon, operated with thermal oil Takttrockners creates the pre-described below gear.

Das Thermoöl wird auf 300°C erhitzt, das Wasser verdampft und das Öl auf Zündtemperatur gebracht. Das Öl wird gezün­ det und der verölte Walzenzunder od. dgl. glüht durch. Da­ bei wird das Thermoöl erhitzt, und der Thermoölerhitzer kann dann abgeschaltet werden. Durch das Variieren der Zugabemengen von veröltem und mit Wasser beaufschlagtem Walzenzunder wird das System ins Gleichgewicht gebracht.The thermal oil is heated to 300 ° C, the water evaporates and brought the oil to ignition temperature. The oil is ignited det and the oily mill scale or the like glows through. There at the thermal oil is heated, and the thermal oil heater can then be switched off. By varying the Amounts of oiled and water-added Roll mill scale, the system is balanced.

Eine weitere Energiegewinnung kann durch eine Abkühl­ schnecke beim Austrag des durchgeglühten Walzenzunders so­ wie durch das Aufbereiten der kondensierten Abgase erfol­ gen.Further energy can be obtained by cooling snail when discharging the annealed roller scale like this as by processing the condensed exhaust gases gene.

Insgesamt wird mit einem sehr effektiven Verfahren eine "Entölung" der eingangs beschriebenen Einsatzmaterialien ohne weiteres auf kostengünstige Weise erreicht.Overall, using a very effective process "Deoiling" of the feed materials described at the beginning easily achieved in a cost-effective manner.
