Abstract

In order to dispose of the dioxins, occurring in the combustion or pyrolysis of waste, in a manner which is not environmentally harmful, according to the invention it is proposed that the exhaust gas of a pyrolysis plant (1) is fed to a combustion chamber (3), in which the pyrolysis gas is burnt at above 1200 DEG C in the said combustion chamber. The exhaust gases of a waste incineration plant (2) are likewise advantageously fed to the pyrolysis gas afterburner (3). <IMAGE>

Description

Beschreibung und Erläuterung zur PatentanmeldungDescription and explanation of the patent application

"Verfahren zur thermischen Umsetzung von Dioxin"."Process for the thermal conversion of dioxin".

Es ist bekannt, Müll zu pyrolysieren.It is known to pyrolyze garbage.

Ebenso ist bekannt, Müll zu verbrennen.It is also known to burn rubbish.

Bekannt ist auch, daß Dioxin beim Müllverbrennen freigesetzt wird.It is also known that dioxin is released when incinerating waste.

Weiterhin ist bekannt, daß Dioxine bei oberhalb 120000 umweltunschädlich verbrannt werden können.It is also known that above 120,000 dioxins are environmentally harmless can be burned.

Jedoch das Verbrennen in Nüllverbrennungskesseln ist mit diesen hohen Temperaturen nur für spezielle Sonderkessel machbar.However, incineration in incinerators is high with these Temperatures only feasible for special special boilers.

Pyrolyseanlagen im Hochtemperaturbereich zeigen ebenfalls Dioxine.Show pyrolysis systems in the high temperature range Likewise Dioxins.

Bei der Pyrolyse wird Pyrogas freigesetzt.Pyro gas is released during pyrolysis.

Dieses Pyrogas wird entweder einem daneben angeordneten Kraftwerk oder Nüllverbrennungskessel zugeleitet oder aber anderen Verwendungszwecken.This pyro gas is either an adjacent power plant or waste incineration boiler or other uses.

Bei der KME wird überwiegend Wert darauf gelegt, Pyrokoks zu erzeugen, um den gewonnenen Koks in den Wintermonaten bzw. bis in die Wintermonate hinein zwischenzulagern, um ihn dann während der Heizperiode zu verbrennen oder aber ihn direkt der Wirbelbettfeuerung oder Kohlefeuerung mittels Aufmahlen mit anderen Kohlesorten zuzuführen, um wärmetechnisch genutzt zu werden.At KME, emphasis is placed on producing pyrocoke, about the coke obtained in the winter months or into the winter months to be temporarily stored in order to burn it during the heating season or else it directly to the fluidized bed combustion or coal combustion by grinding with other types of coal feed in order to be used thermally.

Erfindunsgeman wird vorgeschlagen, das gewonnene Pyrogas einer Brennkammer zuzuleiten, durch die die heißen Abgase der z.B. adaptierten Müllverbrennung und/oder der Pyrolyseanlage direkt zugeführt werden, wobei in dieser Brennkammer das ge-0 wonnene Pyrogas über 1200 C aufgeheizt wird, um dadurch die dioxinbelasteten Abgase durch Nachverbrennung von diesem gefährlichen Stoff zu befreien.According to the invention, it is proposed that the pyro gas obtained be a combustion chamber through which the hot exhaust gases of e.g. adapted waste incineration and / or are fed directly to the pyrolysis plant, with the ge-0 in this combustion chamber recovered pyrogas is heated to over 1200 C to thereby the dioxin contaminated To free exhaust gases from this dangerous substance by afterburning.

In der beiliegenden Zeichnung ist im Schema das erfindungsgemäße Verfahren dargestellt: mit (1) eine KM-knlage; mit (2) die daneben angeordnete Nüllverbrennungsanlage; mit (3) der Nachbrenner; mit (4) der Kamin des Nachbrenners mit einer evtl.In the accompanying drawing, the method according to the invention is shown in the scheme shown: with (1) a KM button; with (2) the waste incineration plant arranged next to it; with (3) the afterburner; with (4) the chimney of the afterburner with a possibly

dazwischengeschalteten Gasreinigung zur Abscheidung anderer Schadstoffkomponenten. Intermediate gas cleaning for the separation of other pollutant components.

Die gezeichnete Ausführung verbindet die Müllverbrennung und die KME bzw. Pyrolyse-Vergasungsanlage mit der Nachbrennkammer.The drawn version combines the waste incineration and the KME or pyrolysis gasification system with the afterburning chamber.
