Abstract
Description
Die Verfahrensweise beschreibt eine wirtschaftliche Möglichkeit zur Anreiche rung von leicht verdampfbaren Metallen oder ihren Oxiden, die in bestimmten Filterstäuben und in erhöhten Mengen anfallen, so daß ihre Aufbereitung und Wiederverwendbarkeit über höhere Konzentrate leichter ermöglicht werden kann.The procedure describes an economical way of enrichment tion of easily evaporable metals or their oxides, which in certain Filter dust and accumulate in large quantities, so that their preparation and Reusability over higher concentrates can be made easier.
Diese Filterstäube fallen immer mehr dadurch an, weil die Verzinkung von Stahlblechen, beispielsweise für die Autokarosserieherstellung, besonders vorteil haft ist, und ihr Schrottanfall beim Wiedereinschmelzen in Stahlwerken und Gießereien zur laufenden Erhöhung in den Filterstäuben führt.This filter dust accumulates more and more because the galvanizing of Steel sheets, for example for the manufacture of car bodies, are particularly advantageous is, and their scrap accumulation when remelting in steel plants and Foundries leads to the continuous increase in the filter dust.
Auf diese Weise werden Grenzwerte für diese Metalle und ihre Oxide in den Filterstäuben überschritten, die ihre Ablagerung auf normalen Halden verbietet, weil sie als Eluate unser Grundwasser verseuchen; und Sonderdeponieablagerun gen hohe Kosten verursachen.In this way, limit values for these metals and their oxides in the Filter dust exceeded, which prohibits their deposition on normal heaps, because they contaminate our groundwater as eluates; and special landfill cause high costs.
Alle Versuche, die hier unternommen wurden, um wirtschaftliche Verfahrens weisen zur Lösung dieser Problematik zu finden, sind an hoher Kostenbelastung gescheitert.All attempts that have been made here to economic process to find ways to solve this problem are at high cost failed.
Hiergegen können nur einfache und weniger kostenbelastende Verfahrensweisen mögliche Umweltgefährdungen beseitigen helfen.Only simple and less costly procedures can counter this help eliminate potential environmental hazards.
Aus der DE-PS 35 05 982 ist bekannt, Filterstäube in flüssige Prozeßschlacken einzublasen und deponierbare Produkte zu erhalten.From DE-PS 35 05 982 it is known to filter dust in liquid process slags blow in and receive depositable products.
Jedoch wird bei diesem Verfahren der steigende Anteil an Zink, Bei oder Cad mium in den anfallenden Filterstäuben nicht berücksichtigt.However, the increasing proportion of zinc, bei or cad mium in the resulting filter dust is not taken into account.
Der Anmeldung liegt daher die Aufgabe zugrunde, ein Verfahren bereit zu stellen, zur Gewinnung von Konzentraten aus leicht verdampfenden Metallen oder ihren Oxiden, insbesondere Zink und Blei, die in Filterstäu ben bei unterschiedlichen Herstellungsprozessen anfallen und deren Mengen anteile relativ gering sind und zur Wiederverwendung oder Aufbereitung nicht ausreichen.The registration is therefore based on the task of having a method ready to provide for the extraction of concentrates from easily evaporating Metals or their oxides, especially zinc and lead, in filter dust ben incurred in different manufacturing processes and their quantities proportions are relatively low and for reuse or processing not suffice.
Die gestellte Aufgabe wird gelöst durch ein Verfahren mit den kenn zeichnenden Merkmalen des Anspruchs 1.The task is solved by a process with the kenn characterizing features of claim 1.
In den Unteransprüchen 2 und 3 sind Ausbildungen des Verfahrens nach Anspruch 1 angegeben.In the dependent claims 2 and 3 are training of the method specified according to claim 1.
Diese neue Verfahrensweise wird dadurch ermöglicht, daß flüssigen Endschlacken bei der Stahl-, Roheisen- oder Gußeisenherstellung, bevor ihre Entleerung aus den Schlackenpfannen erfolgt, die benannten Filterstäube möglichst trocken zugeführt werden. Was eine optimale Verdampfung von o. g. Metallen und ihren Oxiden ermöglicht, so daß über diese Verdampfung mit bekannten Absaugvor richtungen Konzentrate mit hohen Gehalten der benannten Metalle und ihren Oxiden aufgefangen werden. Konzentrate, die einen hohen Wertstoffinhalt haben.This new procedure is made possible by the fact that liquid final slags in steel, pig iron or cast iron production before their emptying the slag pans, the named filter dusts as dry as possible are fed. What an optimal evaporation of the above. Metals and their Oxides allows so that evaporation with known suction directions concentrates with high contents of the named metals and their Oxides are caught. Concentrates that have a high recyclable content to have.
Die Absaugvorrichtungen müssen gegen hohe Wärmestrahlungen entsprechend feuerfeste Auskleidungen oder Kühlsysteme haben.The suction devices must be protected against high heat radiation have refractory linings or cooling systems.
So werden bei diesem Vorgang die schädlichen Bestandteile der Filterstäube getrennt, so daß die Filterstäube keine Eluatträger sind und gleichzeitig bei diesem Vorgang in die ungefährlichen Schlacken eingebunden werden. Damit werden auch diese Schlacken verbessert, wie in der DE-PS 35 05 982 be schrieben ist.In this process, the harmful components of the filter dust become separated so that the filter dusts are not eluate carriers and at the same time this process can be incorporated into the harmless slags. In order to these slags are also improved, as in DE-PS 35 05 982 be is written.
Das gewonnene Konzentrat kann, wenn es aus unterschiedlichen Gründen er forderlich erscheint, flüssig, staubförmig, auch in größeren Körnungen, metal lisch oder oxidisch zur Wiederverwendung im kontinuierlichen Vorgang herge stellt werden, weil dies über bekannte Vorrichtungen und Maßnahmen zu ermög lichen ist.The concentrate obtained can, if it is for different reasons appears to be necessary, liquid, dusty, even in larger grits, metal Lisch or oxidisch for reuse in the continuous process be made because this is possible via known devices and measures is.
Anzumerken ist, daß die Filterstäube auch mit Stickstoff oder Edel- und ande ren Gasen als Transportmittel in die Schlacken einblasbar sind; auch reiner Sauerstoff zugeführt werden kann, um eine spezielle Aufbereitung der benann ten Metalle zu vereinfachen oder zu verbessern.It should be noted that the filter dust also with nitrogen or noble and other Ren gases can be blown into the slags as a means of transport; also purer Oxygen can be supplied to a special treatment of the designated simplify or improve metals.
Die beschriebene Verfahrensweise bietet nicht nur eine Umweltentlastung, sondern auch eine einfache und kostengünstige Entsorgung der gefährlichen Filterstäube!The procedure described not only offers environmental relief, but also an easy and inexpensive disposal of the dangerous Filter dust!
