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 dust 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 deponiert. Diese gemeinsame Deponierung ist jedoch inzwischen in einigen Bundes ländern verboten worden. Teilweise wurden die Filter stäube auch bis zur Staubfreiheit mit Wasser angerührt und in Sondermülldeponien verbracht. In einigen Fällen werden diese Filterstäube in Fässer abgepackt und in Untertage-Mülldeponien verbracht, was jedoch mit erheb lichen Kosten verbunden ist und viel von dem knappen Raum in Untertage-Mülldeponien verbraucht.So far, the filter dusts have been partly together with the slag mixed and deposited. This common However, landfill is now in some federal states countries have been banned. Partially the filters dust also mixed with water until dust-free and spent in hazardous waste landfills. In some cases these filter dusts are packed in barrels and in Underground landfills spent, but with considerable costs and much of the scarce Space in underground landfills used up.
Es ist bekannt, daß 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 that 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 Calciumsulfat-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 und wieder zerrieseln.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 as it has been around for a short time later bloat and drizzle again.
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 Verfahren und ein möglichst geringes Volumen Deponieraum bean spruchen.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 safer than previous methods and the smallest possible volume of landfill space say.
Intensive Untersuchungen verschiedener Filterstäube von Müllverbrennungsanlagen und Müllheizkraftwerken haben ergeben, daß diese Aufgabe gelöst werden kann, indem die Filterstäube gegebenenfalls nach einer wässrigen Auslaugung oder einer ersten Abbindestufe unter Zusatz von Wasser und gegebenenfalls von organischen oder an organischen Bindemitteln entweder zunächst brikettiert, pelletisiert oder stranggepreßt, danach gegebenenfalls grob vermahlen und danach wasserabdichtend umhüllt wer den, oder nach Poctor verdichtet und deponiert werden oder pastös unterirdisch verbracht 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 if necessary after an aqueous Leaching or a first setting step with addition of water and optionally of organic or other organic binders either initially briquetted, pelletized or extruded, then optionally coarsely ground and then coated in a waterproof manner or compacted and deposited according to Poctor or pasty underground.
Als organische oder anorganische Bindemittel kommen insbesondere Zement, Wasserglas, puzzolanisch aktive Flugasche mit oder ohne Zusatz feinteiliger Rauchgas entschwefelungsprodukte oder organische Polymere in Frage. Die wasserabdichtende Umhüllung erfolgt durch organische Polymere, Calciumstearat, Silikonöl, Wachs oder wasserbeständige, hydraulisch und/oder puzzola nisch abbindende Gemische.Coming as organic or inorganic binders especially cement, water glass, pozzolana active Fly ash with or without the addition of finely divided flue gas desulfurization products or organic polymers Question. The waterproof sealing is done by organic polymers, calcium stearate, silicone oil, wax or water resistant, hydraulic and / or puzzola niche setting mixtures.
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 um mehrere Zehnerpotenzen. Dadurch ist es auch technisch und wirtschaftlich möglich, die Produkte wasserabdichtend zu umhüllen. Die so erhalte nen Produkte sind leicht und sicher handhabbar, können kostengünstig transportiert und leicht in die Deponie verbracht werden. Beim Verbringen in Salzkavernen wei sen die erfindungsgemäß erhaltenen Produkte eine ver gleichbare Dichte wie Natriumchlorid auf und können daher sicher und stabil deponiert werden. Das benötigte Volumen beträgt weniger als 50% als bei den bisher durchgeführten Verfahren.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 reduction in size by several powers of ten. Thereby it is also technically and economically feasible To wrap products in a waterproof manner. The so get NEN products are easy and safe to handle transported inexpensively and easily to the landfill to be spent. White in salt caverns sen the products obtained according to the invention ver same density as sodium chloride and can therefore be deposited safely and stably. That needed Volume is less than 50% than the previous one performed procedures.
Zur Durchführung des erfindungsgemäßen Verfahrens wer den die Filterstäube gegebenenfalls nach einer wässrigen Auslaugung oder einer ersten Abbindestufe zunächst unter Zusatz von Wasser und gegebenenfalls von organischen oder anorganischen Bindemitteln briket tiert, pelletisiert oder stranggepreßt. Da die Filter stäube oft einen hohen Gehalt an Calciumchlorid haben, sind sie hygroskopisch und ziehen das notwendige Wasser bereits aus den Rauchgasen bzw. der Luft der Umgebung. Mit bestimmten Mengen an hydraulischen Abbindern wie Zement vermischt und mit Wasser angerührt binden sie locker geschüttet zu einem geblähten und verrieselnden Produkt ab, das leicht zerkleinert und erfindungsgemäß weiterverarbeitet werden kann.To carry out the method according to the invention which the filter dust may be after a aqueous leaching or a first setting stage first with the addition of water and if necessary briket organic or inorganic binders animals, pelletized or extruded. Because the filters dusts often have a high calcium chloride content, they are hygroscopic and draw the necessary water already from the flue gases or the surrounding air. With certain quantities of hydraulic binders such as They are mixed with cement and mixed with water loosely poured into a bloated and trickling Product that is easily crushed and according to the invention can be processed further.
Durch den Zusatz von organischen oder anorganischen Bindemitteln wie Zement, Wasserglas, puzzolanisch akti ve Flugasche unter Zusatz von feinteiligen Rauchgasent schwefelungsprodukten oder organischen Polymeren erhält man beim Brikettieren, Pelletisieren oder Strangpreßen Produkte mit wesentlich höherer Dichte und wesentlich geringerer Oberfläche. Je nach Form und Größe der dabei erhaltenen Primärteilchen ist es möglich, sie unmittel bar wasserabdichtend zu umhüllen. In gewissen Fällen kann es jedoch das Ergebnis erheblich verbessern, wenn die so erhaltenen Produkte zunächst grob vermahlen wer den. Diese Maßnahme empfiehlt sich insbesondere, wenn die Produkte in wasserbeständige, hyraulisch und/oder puzzolanisch abbindende Gemische eingebracht werden sollen. Insbesondere Briketts können aber unmittelbar mit einer wasserabdichtenden Umhüllung versehen werden, wobei dann vorzugsweise organische Polymere, Calcium stearat, Silikonöl oder Wachs in Frage kommen.By adding organic or inorganic Binders such as cement, water glass, pozzolana acti ve fly ash with the addition of finely divided smoke gas sulfur products or organic polymers one when briquetting, pelletizing or extruding Products with much higher density and essential less surface. Depending on the shape and size of the obtained primary particles, it is possible to immediately bar to be sealed in a water-tight manner. In certain cases however, it can significantly improve the result if the products thus obtained are first roughly ground the. This measure is particularly recommended if the products in water-resistant, hydraulic and / or pozzolanic setting mixtures are introduced should. Briquettes in particular can be used immediately be provided with a waterproof cover, then preferably organic polymers, calcium stearate, silicone oil or wax.
Der Transport kann dann ohne weiteres Befeuchten erfol gen, wodurch erhebliche Tonnage eingespart wird. Grob vermahlenes und wasserabdichtend umhülltes Produkt kann auch in Silowagen transportiert und pneumatisch ver bracht werden.The transport can then take place without further moistening gene, which saves considerable tonnage. Rough ground and waterproof sealed product can also transported in silo wagons and pneumatically ver be brought.
Sofern als wasserabdichtende Umhüllung hydraulisch und/ oder puzzolanisch abbindende Gemische verwendet werden, ist es auch möglich, relativ langsam abbindende Gemi sche zu verwenden, wie Transportbeton oder langsam ab bindende Kraftwerkabfallstoffe, enthaltend Flugasche, alkalischen Abbinder und gegebenenfalls Calciumsulfat und Calciumsulfat-/-sulfitgemische, und diese noch fließ- und pumpfähigen Gemische in die unterirdische Deponie zu verbringen. Gut abbindende Gemische können auch nach Proctor maximal verdichtet und deponiert werden, da sie auch von Oberflächenwasser kaum noch ausgelaugt werden. Besonders sicher ist jedoch die Deponierung, wenn die verdichteten und abgebundenen Produkte wasserabdichtend umhüllt sind.If hydraulic and / or waterproof or pozzolanic setting mixtures are used, it is also possible to use relatively slow setting gemi to use as ready-mixed concrete or slowly binding power plant waste, containing fly ash, alkaline setting agent and optionally calcium sulfate and calcium sulfate - / - sulfite mixtures, and these still flowable and pumpable mixtures into the underground To spend landfill. Mixes that set well can maximum compacted and deposited even after Proctor as they are hardly affected by surface water be drained. However, that is particularly safe Landfilling when the compacted and set Products are covered in a waterproof manner.
