Description
Die Erfindung betrifft ein Verfahren zur Herstellung entsorgungsfähiger Filterstäube gemäß dem Oberbegriff des Patentanspruchs.The invention relates to a method for producing disposable filter dusts according to the preamble of the claim.
So sind Filterstäube zu verbessern, indem ihnen CaO, SiO₂, Fe oder andere Stoffe zugemischt werden, um nach der Verfahrensweise des Hauptpatentes 35 05 982 Prozeßschlacken für Straßenbaustoffe und andere Wiederverwendungszwecke geeignet zu machen, was unbekannt ist.So filter dust can be improved by CaO, SiO₂, Fe or others Substances are mixed in according to the procedure of the main patent 35 05 982 Process slag for road building materials and other reuse purposes to make suitable what is unknown.
Bekannt ist dahingegen, daß man Filterstäuben Zusatzstoffe beimischt - Wasser, Zement, auch andere -, aber immer in der Absicht, um Filterstäube auf diese Weise entsorgungsfähig zu machen. Eine Absicht, die nach den verschärften Entsorgungsverfügungen so nicht mehr zu verwirklichen ist.However, it is known that you add filter dust additives - water, cement, also others -, but always with the intention of making filter dust disposable in this way close. An intention that so after the tightened disposal orders is no longer feasible.
Gemäß dem Hauptpatent werden entsorgungsfähige Filterstäube dadurch hergestellt, daß man die Filterstäube flüssigen Prozeßschlacken, die bei der Gewinnung von Roheisen, Stahl oder sonstigen Gießereiprodukten anfallen, zuführt. Die beschriebenen Maßnahmen nach dem Hauptpatent - 35 05 982 - haben sich an sich bewährt.According to the main patent, disposable filter dusts are produced by that the filter dusts are liquid process slags that are involved in the extraction of pig iron, steel or other foundry products. The measures described under the main patent - 35 05 982 - have proven itself.
Der Erfindung liegt nun in weiterer Ausbildung und Verbesserung des Gegenstandes nach dem Hauptpatent die Aufgabe zugrunde, nicht nur die Entsorgung der Filterstäube sicherzustellen, sondern gleichzeitig auch die Wiederverwendung der Prozeßschlacken zu verbessern. Die Lösung dieser Aufgabe erfolgt bei dem gattungsgemäßen Verfahren mit den kennzeichnenden Merkmalen des Patentanspruchs.The invention is now in further training and improvement of the subject based on the main patent, the task, not just the disposal the filter dust, but also reuse to improve the process slags. This task is solved at the generic method with the characterizing features of the claim.
Die Zuführung der Filterstäube in flüssige Prozeßschlacken kann von Hand, mechanisch oder pneumatisch erfolgen, wofür aus vielen Herstellungsbereichen entsprechende Vorrichtungen bekannt sind.The filter dust can be fed into liquid process slags by hand, done mechanically or pneumatically, for which purpose from many manufacturing areas corresponding devices are known.
