Description
Die Erfindung betrifft ein Verfahren zum Umwandeln von Filterstäuben in der Gießereiindustrie zu einem deponie fähigen Produkt.The invention relates to a method for converting Filter dust in the foundry industry at a landfill capable product.
In der Gießereiindustrie muß, wie auch in anderen In dustriezweigen, die Staubemission auf ein umweltver trägliches Maß reduziert werden. Zur Staubrückhaltung dienen überwiegend Filteranlagen, in denen folglich er hebliche Mengen an Filterstäuben anfallen. Stäube ent stehen in unterschiedlichen Bereichen einer Gießerei, z. B. im Schmelzbetrieb als Abgase am Kupol- oder Induk tionsofen, in der Formerei bei der Herstellung der Formen und Kerne, beim Abgießen der Form, beim Ausschlagen der Gußstücke, beim Putzen und Strahlen des Gusses und schließ lich auch bei der Aufbereitung des Formstoffs. Je nach Entstehungsort weist der Staub unterschiedliche Komponenten und Zusammensetzungen auf. So enthält beispielsweise der Staub aus dem Schmelzbetrieb einen hohen Anteil an lungen gängigen Schwermetallen, während der Staub aus der Formerei vornehmlich Formstoff- und Binderpartikel enthält. In der Putzerei wiederum fallen Gemische aus Formstoff und Metallstaub an. In the foundry industry, as in other In branches of industry that reduce dust emissions to an environmental tolerable dimension can be reduced. For dust retention mainly serve filter systems, in which consequently he considerable amounts of filter dust arise. Ent dust stand in different areas of a foundry, e.g. B. in melting operation as exhaust gases on the cupola or induc tion furnace, in the molding shop during the production of the molds and cores, when casting the mold, when knocking out the Castings, when cleaning and blasting the casting and closing Lich also in the preparation of the molding material. Depending on The source of the dust has different components and compositions. For example, the Dust from the melting shop has a high proportion of lungs common heavy metals while the dust from the molding shop mainly contains molding and binder particles. In the blow room in turn contains mixtures of molding material and Metal dust.
Die Filterstäube eines Gießereibetriebes weisen also eine sehr hetorogene Zusammensetzung auf, worunter sich unter Umweltschutzaspekten gefährliche Komponenten befinden. Hier sei nur beispielhaft auf den hohen Anteil an Schwer metallen im Kupolofenstaub verwiesen. Zudem weisen die Filterstäube einen hohen Feinkornanteil und damit flugfä hige Bestandteile auf. Bisher sind diese Filterstäube durch Deponierung entsorgt worden. Die Deponierung wird jedoch zunehmend problematisch, da die Filterstäube auf der De ponie besondere Vorkehrungen erfordern. Soweit Deponien solche Filterstäube überhaupt noch annehmen, entstehen ganz erhebliche Deponiekosten, die den Gießereibetrieb zusätzlich belasten.The filter dust from a foundry therefore has one very heterogeneous composition, including what is Environmental aspects of dangerous components. Here is only an example of the high proportion of heavy metals in the cupola dust. In addition, the Filter dust has a high proportion of fine grains and is therefore flyable components. So far, these filter dusts are through Landfill has been disposed of. The landfill will, however increasingly problematic because the filter dust on the De ponie require special precautions. So far landfills accept such filter dust at all, arise very substantial landfill costs that the foundry operation burden additionally.
Der Erfindung liegt die Aufgabe zugrunde, in der Gießerei- Industrie anfallene Filterstäube in ein deponiefähiges Produkt umzuwandeln.The invention is based, in the foundry Industry-generated filter dust in a landfill-capable Convert product.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Filterstaub mit einem flüssigen Klebebinder gemischt, die Mischung isostatisch zu einem Festkörper verpreßt und der Festkörper als Zuschlagstoff in einem Kupolofen gattiert und verschlackt wird.This object is achieved in that the filter dust is mixed with a liquid perfect binder, the mixture is pressed isostatically into a solid and the solid as an additive in a cupola furnace is gatted and slagged.
Durch das erfindungsgemäße Verfahren werden Gießerei-Fil terstäube zunächst mit einem flüssigen Klebebinder be feuchtet und gemischt. Unter Klebebinder werden hierbei solche Binder verstanden, die allein durch Feuchtigkeit-, insbesondere Wasserabgabe, eine Klebewirkung entfalten. Die nur schwach feuchte Mischung wird anschließend iso statisch verpreßt, d. h. es wird beim Pressen Vorsorge dafür getroffen, daß der maximale Preßdruck auf alle Oberflächen des Festkörpers etwa gleichmäßig zur Wirkung kommt. Der auf diese Weise entstehende Festkörper wird bei der üb lichen Gattierung eines Kupolofens - Heißwind- oder Kalt wind-Kupolofen - als Einsatz aufgegeben. Er wandert beim Ofengang zusammen mit dem Einsatz nach unten. Im Schmelz bereich des Ofens wird der Festkörper zu Schlacke umgewan delt, die mit der üblichen Ofenschlacke oberhalb der Me tallschmelze abgezogen wird. Mit dem erfindungsgemäßen Verfahren können also Filterstäube in einfacher und kosten günstiger Weise in Schlacke überführt werden, in der die einzelnen Komponenten überwiegend in oxidierter und vor allem in nicht mehr eluierfähiger und damit in umweltver träglicher Form vorliegen. Zudem wird ein nicht mehr stau bendes Produkt erzeugt, das sich weit problemloser hand haben und deponieren läßt. Der beim Pressen zum Festkörper aufgewandte Druck und der Gehalt an Klebebinder müssen so ausgelegt werden, daß der entstehende Festkörper eine ausreichende Druckfestigkeit aufweist, um beim Ofengang nicht zu zerfallen. Diese beiden Parameter sind an die jeweilige Zusammensetzung und Konsistenz der verarbeiteten Filterstäube anzupassen.The inventive method foundry Fil First dust with a liquid perfect binder moist and mixed. Here under perfect binder understood such binders that are in particular water release, develop an adhesive effect. The slightly damp mixture then becomes iso statically pressed, d. H. it becomes precautionary when pressing hit that the maximum baling pressure on all surfaces of the solid body has an approximately uniform effect. The in this way resulting solid is at the ex genus of a cupola furnace - hot wind or cold wind cupola furnace - abandoned as insert. He walks around Oven aisle together with the insert down. In the enamel In the area of the furnace, the solid is turned into slag delt that with the usual furnace slag above the Me tall melt is withdrawn. With the invention Processes can filter dust in simple and cost be conveniently converted into slag in which the individual components predominantly in oxidized and pre especially in no longer elutable and thus in environmental present in inert form. In addition, there is no more traffic jam producing product that is far easier to handle have and have deposited. The one when pressing to the solid applied pressure and the content of perfect binder must be so be interpreted that the resulting solid a has sufficient compressive strength to go through the furnace not to disintegrate. These two parameters are related to the respective composition and consistency of the processed Adapt filter dust.
Es ist zwar bekannt (EP 2 96 188 A1), in der Gießerei- Industrie anfallende Filterstäube im Kupolofen in Schlacke umzuwandeln, jedoch geschieht dies auf ungleich aufwen digere und in der Anwendung beschränkten Weise. Es wird nämlich der Filterstaub zusammen mit Abfallkoks am Heiß windring des Kupolofens eingeblasen. Dieses Verfahren hat sich bisher nur bei Heißwind-Kupolöfen bewährt, während bei Kaltwind-Kupolöfen wirtschaftliche Gesichtspunkte gegen seine Anwendung sprechen. Ferner macht diese Ver arbeitung der Stäube eine bauaufwendige und damit inve stive Anlagentechnik (Silos, pneumatische Förderung ect.) erforderlich. It is known (EP 2 96 188 A1) in which foundries Industrial filter dust in the cupola furnace in slag convert, however, this happens on unequal expenses digere and limited in use. It will namely the filter dust together with waste coke on hot Wind cup of the cupola blown. This method has so far only proven itself in hot wind cupola furnaces, while economic aspects in cold wind cupola furnaces speak against its application. Furthermore, this ver processing of the dusts is a complex and thus inves stive systems engineering (silos, pneumatic conveying, etc.) required.
Praktische Versuche mit dem erfindungsgemäßen Verfahren haben gezeigt, daß die Mischung aus Filterstaub und Klebe binder bei über 1000 bar, vorzugsweise im Bereich von 3000 bar isostatisch verpreßt werden sollte, um dem Festkörper eine für den Ofengang ausreichende Festigkeit zu verleihen.Practical experiments with the method according to the invention have shown that the mixture of filter dust and adhesive binder at over 1000 bar, preferably in the range of 3000 bar should be pressed isostatically to the solid to provide sufficient strength for the furnace operation.
Bei Drücken der vorgenannten Höhe läßt sich die Mischung beim Verpressen auf 1:10 bis 1:20 verdichten, also eine ganz erhebliche Volumenreduzierung erreichen. Die Festkör per können grundsätzlich beliebige Form aufweisen, lassen sich aber dann mit größtmöglicher Festigkeit herstellen, wenn sie zu Kreiszylindern gepreßt werden. Sie weisen dann auch eine gute Ofengängigkeit auf.The mixture can be pressed at the above-mentioned height compress to 1:10 to 1:20, i.e. one achieve very substantial volume reduction. The solids can basically have any shape but then manufacture with the greatest possible strength, when they are pressed into circular cylinders. You then point also a good ovenability.
Als Klebebinder werden vorzugsweise natürliche Binder, z. B. Glucosesirup, Maisstärke, Wasserglas od. dgl., ver wendet. Praktische Untersuchungen haben gezeigt, daß solche Klebebinder einerseits einen sehr geringen Bindereinsatz erfordern, um gleichwohl bruchfeste Preßlinge zu erhalten, andererseits in kurzer Zeit eine ausreichende Klebewirkung entfalten, so daß keine langen Trocknungszeiten notwendig sind.Natural binders are preferably used as adhesive binders, e.g. B. glucose syrup, corn starch, water glass or the like, ver turns. Practical studies have shown that such Adhesive binder, on the one hand, requires very little binder require in order to nevertheless obtain unbreakable compacts, on the other hand, a sufficient adhesive effect in a short time unfold so that no long drying times are necessary are.
Das erfindungsgemäße Verfahren kann weiterhin dahingehend abgewandelt werden, daß der Mischung aus Filterstaub und Klebebinder übliche Einsatzstoffe für den Kupolofen-Betrieb in pulvriger bis körniger Form zugesetzt werden. Als Ein satzstoffe werden hierbei alle Stoffe verstanden, die entweder bei der Gattierung des Ofens oder aber erst der abgezogenen Schmelze zugegeben werden. Es kann sich also um Kalk, Koks- oder Kohlestaub, um Siliziumpulver od. dgl. handeln. The method according to the invention can also go in this regard be modified that the mixture of filter dust and Perfect binders common feedstocks for cupola operation in powdery to granular form. As a Substances are understood to mean all substances that either in the genus of the furnace or only the withdrawn melt are added. So it can lime, coke or coal dust, silicon powder or the like. act.
Ebenso ist es möglich, der Mischung Metallstäube oder Metallspäne aus der spanenden Verarbeitungstechnik zu zusetzen.It is also possible to mix the metal dusts or Metal chips from machining technology too clog.
Mit dem Verfahren gemäß der Erfindung ist eine kosten günstige Verarbeitung der umweltkritischen Filterstäube zu einer deponiefähigen Schlacke möglich.With the method according to the invention is a cost Favorable processing of the environmentally critical filter dust possible for a slag that can be landfilled.
