Description
Die Erfindung betrifft ein Verfahren nach den Merkmalen des ersten Patentanspruches und einen Flugstromvergaser zur Durchführung des Verfahrens. Die Erfindung ist überall dort anwendbar, wo halogenbelastete kohlenstoffhaltige Rest- und Abfallstoffe unter Erzeugung eines kohlenmonoxid- und wasserstoffhaltigen Gases bei gleichzeitiger Gewinnung von halogenhaltigen Wertstoffen zu verwerten sind.The The invention relates to a method according to the features of the first claim and an entrained-flow gasifier for carrying out the method. The invention is everywhere applicable where halogenated carbonaceous residual and Waste materials producing a carbon monoxide and hydrogen-containing Gas with simultaneous recovery of halogenated recyclables to be used.
Unter halogenbelasteten kohlenstoffhaltigen Rest- und Abfallstoffen sind mit organischen oder anorganischen Halogenverbindungen belastete Kohlenwasserstofföle, chlorhaltige Kunststoffe, halogensalzinfiltrierte kohlenstoffhaltige Materialien, mit Halogenverbindungen belastete Klärschlämme, verunreinigte Halogenwasserstoffsäuren sowie verunreinigte Halogenkohlenwasserstoffe oder deren Mischungen zu verstehen.Under Halogen-loaded carbonaceous residues and waste materials are loaded with organic or inorganic halogen compounds Hydrocarbon oils, chlorine-containing plastics, halogen-salt-filtered carbonaceous materials Materials, sewage sludge contaminated with halogen compounds, contaminated Hydrogen halides as well as contaminated halogenated hydrocarbons or mixtures thereof to understand.
Es ist bekannt, halogen- und kohlenstofhaltige Rest- und Abfallstoffe unter Nutzung der entstehenden Wärme sowie zur Gewinnung halogenhaltiger Wertstoffe zu verbrennen oder zu vergasen.It is known, halogen and carbonaceous residues and waste using the heat generated as well as to recover halogenated recyclables or to gas.
Bei der Verbrennung besteht jedoch die Gefahr der Bildung von hochtoxischen Substanzen, die sowohl das Abgas oder auch gewonnene Wertstoffe, wie beispielsweise Salzsäure, belasten. So führen bereits geringe Gehalte von polychlorierten Biphenylen, wie vielfach in Altölen aus elektronischen Einrichtungen und Hydraulikanlagen gefunden, zur Gefahr der Bildung von extrem toxischen polychlorierten Dibenzodioxinen (PCDD) und Dibenzofuranen (PCDF). Eine zusammenfassende Darstellung ist gegeben in "Dioxine – Entstehung, Verteilung und Eintrag in die Umwelt", Prof. Dr. Hutzinger, Nov. 1990, Universität Bayreuth.at however, there is a risk of the formation of highly toxic combustion Substances containing both the exhaust gas or recovered valuable materials, such as for example, hydrochloric acid, strain. So already lead low levels of polychlorinated biphenyls, as many in waste oils found from electronic devices and hydraulic systems, the danger of formation of extremely toxic polychlorinated dibenzodioxins (PCDD) and dibenzofurans (PCDF). A summary is given in "Dioxin - Genesis, Distribution and Entry into the Environment ", Prof. Dr. Hutzinger, Nov. 1990, University of Bayreuth.

der Technik der Gaserzeugung ist die Verwertung halogenbelasteter
Rest- und Abfallstoffe langjährig bekannt.
So beschreibt
Während des Vergasungsprozesses gebildeter Ruß sowie Reste von höhermolekularen organischen und halogenorganischen Verbindungen erfordern eine aufwendige Aufbereitung des Vergasungsgases und beeinträchtigen die Qualität und Verwertbarkeit der halogenhaltigen Wertstoffe wie beispielsweise Salzsäure, die durch Absorption von Chlorwasserstoff in Wasser in Quench- und nachfolgenden Waschprozessen gewonnen wird. Weiterhin führen die im Vergasungsprozess gebildeten Ruß- und Reststoffe zur Korrosion der Anlage.During the Gasification process formed soot and residues of higher molecular weight Organic and halogenated organic compounds require a complex Treatment of the gasification gas and affect the quality and usability the halogen-containing recyclables such as hydrochloric acid, the by absorption of hydrogen chloride in water in quench and subsequent Washing processes is won. Furthermore, the lead in the gasification process formed soot and residues to Corrosion of the plant.
Der Erfindung liegt die Aufgabe zugrunde, die Möglichkeit der Vergasung nach dem Prinzip der partiellen Oxydation im Flugstrom für die Verwertung halogenhaltiger Rest- und Abfallstoffe zu nutzen und ein vielseitig einsetzbares kohlenmonoxid- und wasserstoffhaltiges Gas und hochqualitative Wertstoffe, wie Halogenwasserstoffsäuren oder Halogensalze, so zu erzeugen, dass aus dem Halogengehalt des Einsatzmaterials resultierende Umweltbelastungen für Atmosphäre, Wasser und Boden durch toxische Stoffe vermieden und Korrosionen in der entsprechenden Anlage weitgehend eingeschränkt bleiben.Of the Invention is based on the object, the possibility of gasification the principle of partial oxidation in the air stream for the utilization of halogenated To use residual and waste materials and a versatile one carbon monoxide and hydrogen-containing gas and high quality recyclables, such as Hydrogen halides or halogen salts, so as to generate from the halogen content of the feedstock resulting environmental pollution for atmosphere, water and soil Avoiding toxic substances and corrosion in the corresponding Plant largely restricted stay.
Diese Aufgabe wird durch ein Verfahren nach den Merkmalen des ersten Patentanspruches und einen Flugstromvergaser zur Durchführung des Verfahrens gelöst.This task is performed by a procedure solved according to the features of the first claim and a Flugstromvergaser for performing the method.
Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.Subordinate claims advantageous embodiments of the invention again.
Das erfindungsgemäße Verfahren geht davon aus, dass halogenenthaltende und kohlenstoffhaltige Rest- und Abfallstoffe in einem fließfähigen Zustand und ein freien Sauerstoff enthaltendes Vergasungsmittel in Form einer Flammenreaktion bei einem erhöhten Druck mehrstufig zu einem kohlenmonoxid-, wasserstoft- und halogenwasserstoffhaltigen Rohgas umgesetzt werden.The inventive method assumes that halogen-containing and carbon-containing residuals and waste in a flowable state and a free oxygen-containing gasification agent in the form a flame reaction at an elevated pressure in several stages to one carbon monoxide, hydrogen and hydrogen halide-containing raw gas be implemented.
Erfindungsgemäß wird das bei einer Temperatur von mindestens 1100 °C in einer ersten Reaktionskammer erzeugte Rohgas, das noch nicht umgesetzte Bestandteile aufweist, weiteren Reaktionskammern zugeführt, in denen durch die Strömungsführung eine intensive Durchmischung erfolgt, die zum weiteren Umsatz der noch nicht vergasten Bestandteile führt. Zur Steuerung der Reaktion kann den nachgeordneten Reaktionskammern zusätzlich freien Sauerstoff enthaltendes Vergasungsmittel zugeführt werden.According to the invention at a temperature of at least 1100 ° C in a first reaction chamber produced raw gas, which has unreacted constituents, fed to further reaction chambers, in which by the flow guide a intensive mixing takes place, which is to further sales of the still does not lead to gasified ingredients. To control the reaction can be the downstream reaction chambers additionally free Oxygen-containing gasification agent can be supplied.
Die Vorrichtung zur Durchführung des Verfahrens weist mindestens zwei oder mehr hintereinander angeordnete Reaktionsräume auf. Diese können unterschiedlich groß sein und durch sich verengende Querschnitte oder geteilte Zwischenböden voneinander abgegrenzt sein. Sie können auch in eigenen, miteinander verbundenen Druckkörpern angeordnet sein.The Apparatus for carrying out of the method has at least two or more consecutively arranged reaction spaces on. these can be different in size and by narrowing cross-sections or divided shelves from each other be delimited. You can be arranged in its own, interconnected pressure bodies.
