Die Erfindung betrifft eine Anlage zur Verglasung von Reststoffen, wie Klärschlämmen, kontaminierten Schlämmen oder Böden, Schlacken, Filterstäuben, insbesondere aus Müllverbrennungsanlagen und dergleichen, bestehend aus einer Aufbereitungsanlage für die Reststoffe, einer Gemengeanlage zur Mischung und Dosierung der aufbereiteten Reststoffe und Glasbildner, einer mit Feuerung betriebenen Glasschmelzanlage zum Aufschmelzen des Gemenges, die mit einer Einrichtung zur regenerativen Wärmerückgewinnung aus den Rauchgasen der Feuerung gekoppelt ist, wobei die Rauchgase über eine Reinigungsanlage abgegeben werden, als Zusatz zu P 44 35 166.6, wobei zwischen die Gemengeanlage zum Mischen und Dosieren der Reststoffe und Glasbildner und die Glasschmelzanlage eine Vorrichtung zur Trocknung, Entgasung, Oxidation und Sinterung des dosierten Gemenges eingeschaltet ist, insbesondere ein Drehherdofen, der mit fossilen und/oder anderen Brennstoffen beheizt ist und in den vorgewärmte Verbrennungsluft einführbar ist, erste Regeneratoren zur Erhitzung der Verbrennungsluft für die Glasschmelz anlage im Gegenstrom zur zugeführten Verbrennungsluft vom Abgas der Glasschmelzanlage durchströmt sind, wobei die Abgastemperatur beim Durchsatz der Regeneratoren auf einem solchen Niveau gehalten ist, daß eine Kondensatbildung vermieden ist, und den Regeneratoren ein Rekuperator nachgeschaltet ist, der vom Abgas durchströmt ist und in dem dessen Kondensate aus der Dampfphase abgeschieden und der Aufbereitungsanlage zugeführt werden, wobei im Rekuperator die Verbrennungsluft für den Drehherdofen oder dergleichen vorgewärmt wird.The invention relates to a system for glazing Residues such as sewage sludge, contaminated sludge or soils, slags, filter dusts, in particular Incineration plants and the like, consisting of a processing plant for the residues, one Batch system for mixing and dosing the processed Residues and glass formers, one with firing Glass melting plant for melting the batch, the with a device for regenerative heat recovery is coupled from the flue gases of the furnace, whereby the flue gases are released via a cleaning system, as an addition to P 44 35 166.6, whereby between the Batch system for mixing and dosing the residues and glass former and the glass melting system a device for drying, degassing, oxidation and sintering of the metered batch is switched on, in particular a Rotary hearth furnace with fossil and / or other The fuel is heated and preheated Combustion air can be introduced, first regenerators for heating the combustion air for the glass melt system in counterflow to the supplied combustion air are flowed through by the exhaust gas from the glass melting system, wherein the exhaust gas temperature during the throughput of the regenerators is kept at such a level that a Condensation is avoided, and the regenerators a recuperator is connected downstream from the exhaust gas is flowed through and in whose condensates from the Vapor phase separated and the processing plant are supplied, the in the recuperator Combustion air for the rotary hearth furnace or the like is preheated.
Eine derartige Anlage ist mit ihren Vorteilen in der Hauptanmeldung beschrieben. Gemäß Vorschlag der Hauptanmeldung wird das gesamte Abgas der Anlage durch die Regeneratoren geleitet. Infolge der den Drehherdofen verlassenden und durch den Glasschmelzofen geführten Abgasmenge werden die Regeneratoren zu heiß, da die im Gegenstrom aufzuheizende Verbrennungsluftmenge für den Glasschmelzofen im Volumen erheblich geringer ist.Such a system is with its advantages in the Main application described. According to the proposal of the The main application is the entire exhaust gas from the system headed the regenerators. As a result of the rotary hearth furnace leaving and guided through the glass melting furnace Exhaust gas volume, the regenerators are too hot, because the in Amount of combustion air to be heated for the counterflow Glass melting furnace is significantly lower in volume.
Um eine Überhitzung der Regeneratoren zu vermeiden wird demzufolge vorgeschlagen, daß die Abgase des Drehherdofens oder dergleichen einer fossil beheizten Abgasnachverbrennungsstufe zugeführt sind, deren Ausgang an zweite Regeneratoren angeschlossen ist, daß das aus diesem austretende Abgas mit dem Abgas vereinigt wird, welches die ersten Regeneratoren verläßt, und der vereinigte Abgasstrom in den Rekuperator eingeführt wird, daß die im Rekuperator vorgewärmte Verbrennungsluft der Abgasnachverbrennungsstufe im Gegenstrom zum Abgas durch die zweiten Regeneratoren geführt ist, ebenso wie die Verbrennungsluft für den Drehherdofen oder dergleichen, wobei die Abgastemperatur auch beim Durchsatz der zweiten Regeneratoren auf einem die Kondensatbildung vermeidenden Niveau gehalten ist. To avoid overheating the regenerators therefore proposed that the exhaust gases from the rotary hearth or the like of a fossil-heated Exhaust afterburning stage are supplied, the output is connected to second regenerators, that from this exiting exhaust gas is combined with the exhaust gas, which leaves the first regenerators, and the combined exhaust gas flow is introduced into the recuperator, that the preheated combustion air in the recuperator Exhaust gas post-combustion stage in counterflow to the exhaust gas the second regenerators is run, as is the Combustion air for the rotary hearth furnace or the like, the exhaust gas temperature even with the throughput of the second Regenerators on one to avoid the formation of condensate Level is maintained.
Bei dieser Anlagekonzeption wird das den Drehherdofen verlassende Abgas in einer mit fossilen oder anderen Brennstoffen beheizten Abgasnachverbrennung nachverbrannt, wobei die Abgase, die die Abgasnachverbrennung verlassen, durch zweite Regeneratoren geleitet und danach mit dem Abgasstrom vereinigt, der die ersten Regeneratoren verläßt. Der gesamte Abgasstrom wird dann zum Rekuperator geführt und weiterbehandelt. Die Verbrennungsluft für den Drehherdofen wird durch den Rekuperator geleitet und dort vorgeheizt und anschließend in den zweiten Generatoren im Gegenstrom zum Abgas geführt und auf das erforderliche hohe Temperaturniveau gebracht und anschließend teilweise in die Abgasnachverbrennung und teilweise in den Drehherdofen eingeleitet.With this system design, it becomes the rotary hearth furnace leaving exhaust gas in one with fossil or other Fuels heated exhaust gas afterburning, the exhaust gases leaving the exhaust gas afterburner passed through second regenerators and then with the Exhaust gas stream combines the first regenerators leaves. The entire exhaust gas flow then becomes a recuperator managed and further processed. The combustion air for the rotary hearth furnace is passed through the recuperator and preheated there and then in the second Generators in counterflow to the exhaust gas and on the brought required high temperature level and then partly in the exhaust gas afterburning and partially introduced into the rotary hearth furnace.
Durch die Anlagekonstruktion wird eine Überhitzung der ersten Regeneratoren vermieden und dennoch eine weitgehende Nutzung des Wärmeinhaltes der Abgase der Nachverbrennung realisiert. Overheating of the system is prevented first regenerators avoided and still one extensive use of the heat content of the exhaust gases Afterburning realized.
Nachstehend ist anhand eines Ablaufschemas der Verfahrens ablauf bei der erfindungsgemäßen Anlage verdeutlicht.Below is a flow chart of the process process clarified in the system according to the invention.
Die einzige Zeichnungsfigur zeigt ein Konzept einer Einschmelz- und Remineralisierungsanlage (Anlage zur Verglasung von Reststoffen).The only drawing figure shows a concept of one Melting and remineralization plant (plant for Glazing of residues).
Im Unterschied zur Hauptanmeldung ist bei diesem Anlage konzept das Abgas des Drehherdofens über eine Abgas nachverbrennung nicht in dem Glasschmelzofen eingeführt, sondern das Abgas wird in einer Abgasnachverbrennung verbrannt und dann zweiten Regeneratoren zugeführt. Nach Verlassen der zweiten Regeneratoren wird diese Abgasmenge mit der Abgasmenge vereinigt, die die ersten Regeneratoren verläßt, die vom Abgas des Glasschmelzofens durchströmt sind. Die vereinigte Abgasmenge wird dem Rekuperator zugeführt. Das zur Abgasnachverbrennung notwendige Heizmedium wird der Abgasnachverbrennung unmittelbar zugeführt. Die erforderliche Verbrennungsluft wird über den Rekuperator vorgewärmt und dann durch die zweiten Regeneratoren im Gegenstrom zum Abgas geführt und noch weiter erhitzt, um dann teilweise in die Abgas nachverbrennung und teilweise in den Drehherdofen eingeführt zu werden.In contrast to the main application for this system concept the exhaust of the rotary hearth furnace via an exhaust afterburning not introduced in the glass melting furnace, but the exhaust gas is in an exhaust gas afterburning burned and then fed to second regenerators. To This amount of exhaust gas leaves the second regenerators combined with the amount of exhaust gas that the first regenerators leaves, which flows through the flue gas from the glass melting furnace are. The combined amount of exhaust gas is the recuperator fed. The necessary for exhaust gas afterburning The heating medium becomes the exhaust gas afterburning immediately fed. The required combustion air is over preheated the recuperator and then through the second regenerators in counterflow to the exhaust gas and heated further, then partially in the exhaust afterburning and partly in the rotary hearth furnace to be introduced.
