Description
Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Deponierung von Filterstäuben aus Müllverbrennungs anlagen, die bei der mechanischen und/oder elektrosta tischen Rauchgasentstaubung anfallen. In Müllverbren nungsanlagen und Müllheizkraftwerken mit trockener oder quasitrockener Rauchgasreinigung fallen neben den un problematischen Schlacken (ca. 90%) Filterstäube mit hohen Gehalten an Chlorid und erheblichen Mengen an Schwermetall an. Daneben enthalten diese Stäube meist große Mengen an überschüssigem Absorptionsmittel in Form von Calciumhydroxid. Diese Filterstäube fallen in ca. 9% an und bereiten wegen ihrer Zusammensetzung und Eigenschaften erhebliche Probleme bei der Deponierung. Schließlich fällt in einigen Müllverbrennungsanlagen und Müllheizkraftwerken noch ein Restprodukt bei der Rauchgaswäsche an. Die Rückstände hieraus betragen etwa 1% der anfallenden Feststoffe.The present invention relates to a method for depositing filter dust from waste incineration systems used in mechanical and / or electrosta tables of smoke evacuation. In garbage burners plants and waste-to-energy plants with dry or quasi dry flue gas cleaning fall next to the un problematic slags (approx. 90%) with filter dusts high levels of chloride and considerable amounts of Heavy metal. In addition, these dusts mostly contain large amounts of excess absorbent in Form of calcium hydroxide. These filter dusts fall into approx. 9% and prepare for their composition and Features significant landfill problems. Eventually falls in some waste incineration plants and waste-to-energy plants still a residual product at Flue gas scrubbing. The residues from this amount to approximately 1% of the resulting solids.
Die Filterstäube wurden bisher teilweise zusammen mit den Schlacken vermischt und oberirdisch deponiert. Diese gemeinsame Deponierung ist jedoch inzwischen in einigen Bundesländern verboten worden. Teilweise wurden die Filterstäube auch bis zur Staubfreiheit mit Wasser ange rührt und in oberirdischen Sondermülldeponien ver bracht. In einigen Fällen werden diese Filterstäube in Behältnisse abgepackt und in Untertagedeponien ver bracht, was jedoch mit erheblichen Kosten verbunden ist und viel von dem knappen Raum in Untertagedeponien ver braucht.So far, the filter dusts have been partly together with the slag mixed and deposited above ground. These However, common landfill is now in some Federal states have been banned. Some of them Filter dust also supplied with water until it is dust-free stirs and ver in above ground hazardous waste landfills brings. In some cases, these filter dusts are in Containers packed and packed in underground landfills brings, but this is associated with considerable costs and a lot of the scarce space in underground landfills needs.
Es ist bekannt, Filterstäube aus Müllverbrennungs anlagen wässrig auszulaugen und dadurch insbesondere die in verdünnten Säuren löslichen Bestandteile zu ex trahieren. Die ungelösten Rückstände sind dadurch we sentlich unproblematischer und können leichter depon iert werden. Sie sind jedoch immer noch nicht geeignet, in einfache Deponien verbracht zu werden.It is known to filter dust from waste incineration leach systems out, and thereby in particular the components soluble in dilute acids to ex trahieren. The undissolved residues are we considerably less problematic and can be deposited more easily be. However, they are still not suitable to be taken to simple landfills.
Es sind weiterhin Versuche durchgeführt worden, hoch chloridhaltige und Calicumsulfat-haltige Filterstäube aus Müllverbrennungsanlagen mit einem hydraulischen Binder wie Zement anzurühren und abbinden zu lassen. Die dabei anfallenden Produkte haben sich jedoch als völlig instabil erwiesen, da sie bereits kurze Zeit später stark blähen, wieder zerrieseln und durch den Regen völlig ausgelaugt werden.Attempts have continued to be made, high filter dust containing chloride and calcium sulfate from waste incineration plants with a hydraulic Mix binders like cement and let them set. The resulting products, however, have proven to be proven to be completely unstable since it was already short time later bloat, drizzle again and through the Rain can be drained completely.
Die Erfindung hat sich die Aufgabe gestellt, die Depo nierung von Filterstäuben aus Müllverbrennungsanlagen zu verbessern und zu vereinfachen. Dabei soll die Depo nierung auch sicherer sein als die bisherigen Verfah ren, die Abfalleinbringrate in das Deponieendprodukt möglichst hoch sein und damit und ein möglichst ge ringes Volumen Deponieraum beanspruchen. Weiterhin soll der Anteil an Bindemittell bezogen auf das zu deponie rende Produkt möglichst klein gehalten werden. Trotz dem soll das Gemisch am Ende gut abbinden.The invention has set itself the task of the depo nation of filter dusts from waste incineration plants to improve and simplify. The depo be more secure than previous procedures ren, the waste introduction rate into the landfill end product be as high as possible and therefore a ge as possible occupy a small volume of landfill space. Furthermore should the proportion of binding agent related to the landfill product should be kept as small as possible. Despite the mixture should bind well at the end.
Intensive Untersuchungen verschiedener Filterstäube von Müllverbrennungsanlagen und Müllheizkraftwerken haben ergeben, daß diese Aufgabe gelöst werden kann, indem die Filterstäube nach einer wässrigen Auslaugung unter Zusatz von anorganischen Bindemitteln nach Proctor ver dichtet und oberirdisch deponiert werden.Intensive investigations of various filter dusts from Have waste incineration plants and waste incineration plants show that this problem can be solved by the filter dust after an aqueous leaching under Addition of inorganic binders according to Proctor ver sealed and deposited above ground.
Als anorganische Bindemittel kommen insbesondere Zement oder puzzolanisch aktive Flugasche mit oder ohne Zusatz feinteiliger Rauchgasentschwefelungsprodukte in Frage. In particular, cement is used as the inorganic binder or pozzolanic fly ash with or without addition finely divided flue gas desulfurization products in question.
Durch das erfindungsgemäße Verfahren ist es möglich, das Volumen der zu deponierenden Produkte um mehr als 50% zu reduzieren. Außerdem erreicht man eine Oberflä chenverkleinerung des Verfestigungsproduktes im Vergleich zum Anfallzustand um mehrere Zehnerpotenzen.The method according to the invention makes it possible to the volume of the products to be deposited by more than Reduce 50%. You also get a surface Chen reduction of the solidification product in the Compared to the state of seizure by several powers of ten.
Die so erhaltenen Produkte sind leicht und sicher handhabbar, können kostengünstig transportiert und leicht in die Deponie verbracht werden.The products thus obtained are light and safe manageable, can be transported inexpensively and easily be brought to the landfill.
Zur Durchführung des erfindungsgemäßen Verfahrens wer den die Filterstäube nach einer wässrigen Auslaugung mit anorganischen Bindemitteln versetzt und vermischt.To carry out the method according to the invention the filter dust after an aqueous leaching mixed with inorganic binders.
Der Transport kann dann ohne weiteres Befeuchten erfol gen, wodurch erhebliche Tonnage eingespart wird.The transport can then take place without further moistening gene, which saves considerable tonnage.
Die gut abbindenden Gemische werden deponiert und nach Proctor maximal verdichtet, und werden danach auch von Oberflächenwasser kaum noch ausgelaugt.The well-setting mixtures are deposited and subsequently Proctor compressed to a maximum, and are then also from Surface water barely drained.
