Description

Verfahren zur Schoc ühlurig von HochtemperaturgasenProcess for high-temperature gases
Die vorliegende Erfindung beschäftigt sich mit der Schockkühlung von Hochtemperaturgasen entsprechend einer Vorrichtung nach Patentanspruch 1 und eines Verfahrens nach Anspruch 9. Desweiteren betrifft die Erfindung die Verwendung der erfindungsgemäßen Vorrichtung und des erfindungsgemäßen Verfahren m einem Hochtemperaturrecyclingverfahren nach Anspruch 15.The present invention relates to the shock cooling of high-temperature gases in accordance with a device according to claim 1 and a method according to claim 9. Furthermore, the invention relates to the use of the device and the method according to the invention in a high-temperature recycling process according to claim 15.
In der Hochtemperaturverfahrenstechnik werden bei einer Vielzahl von Anwendungsfällen Rauchgase durch Zugabe von Flüssigkeiten wie zum Beispiel Wasser schockartig abgekühlt. Man spricht hierbei vom Vor- gang des Quenchens, der dafür genutzte Apparat ist die sogenannte Quench.In high-temperature process engineering, flue gases are cooled in a shock-like manner by adding liquids such as water in a large number of applications. One speaks here of the process of quenching, the apparatus used for this is the so-called quench.
Das Wasser wird mittels Quenchpumpen im Kreislauf geführt. Zwischen Wassereintritt und Austritt erwärmt sich das Quenchwasser um ca. 10 bis 30 °'C. Diese W r- meenergie wird mittels Quenchwärmetauscher aus dem System abgeführt .The water is circulated by means of quench pumps. Between the water inlet and outlet of the quench water heated to about 10 to 30 ° 'C. This W r- Meenergy is removed from the system using a quench heat exchanger.
Charakteristisch für den Prozess ist, dass neben der Abkühlung des Gases auch im Gas befindliche Fremdstoffe in der Flüssigkeit abgeschieden werden. Eine Verschmutzung der Wärmetauscher, der Rohrleitungen sowie aller guenchwasserführenden Apparate ist nicht vermeidbar. Deshalb ist eine wiederholte Reinigung notwendig.A characteristic of the process is that in addition to the cooling of the gas, foreign substances in the gas are also separated in the liquid. Contamination of the heat exchangers, the pipelines and all the equipment that carries guenchwater is unavoidable. Repeated cleaning is therefore necessary.
Aufgabe der Erfindung ist es, eine Vorrichtung und ein Verfahren anzugeben, bei dem zum einen die Abkühlung der Gase mit hoher Effizienz erfolgen kann, und zum anderen die Reinigungsarbeiten auf ein Mindest- mass reduziert werden können. Des Weiteren ist derThe object of the invention is to provide a device and a method in which, on the one hand, the gases can be cooled with high efficiency, and on the other hand, the cleaning work can be reduced to a minimum. Furthermore, the
Ziel der vorliegenden Erfindung eine Verwendung einer solchen Vorrichtung und eines solchen Verfahrens anzugeben.The aim of the present invention to provide a use of such a device and such a method.
Diese Aufgabe wird erfindungsgemä ' durch eine Vorrichtung gemäß Patentanspruch 1, ein Verfahren gemäß Patentanspruch 9 und durch eine Verwendung gemäß. Patentanspruch 15 gelöst.This object is according to the invention 'by an apparatus according to claim 1, a method according to claim 9 and by a use in accordance with. Claim 15 solved.
Demnach wird zur erfindungsgemäßen Lösung der- Aufgäbe der Schockkühlung des Hochtemperaturgases, die Entwicklung einer Zweistu en-Quench vorgeschlagen. In ~ zwei entlang der Strömungsrichtung des' Hochtemperaturgases nacheinander lokalisierte Stufen bzw. Berei- ehe des Hochtemperaturgasstromes wird die Kühlung ü- ber zwei separate Kühlkreisläufe vorgenommen. Das Quenchwasser wird demnach in zwei getrennten Kreisläufen im Umlauf gehalten.Accordingly, the development of a two-stage quench is proposed for the solution according to the invention of the tasks of shock cooling the high-temperature gas. Localized stages or Berei- before in ~ two successively along the flow direction of the 'high temperature gas of the high temperature gas stream is the cooling Ü over two separate cooling circuits made. The quench water is therefore kept in circulation in two separate circuits.
Kreislauf 1 dient zur eigentlichen Schockkühlung des Hochtemperaturgases in einem entlang der Strömungs- richtung des Gases ersten Bereich, ■ wobei hier auch die im Gas enthaltenen festen Partikel abgeschieden werden, - Kreislauf 2 dient zur abschließenden Kühlung in einem entlang der Strömungsrichtung des Gases zweiten Bereich auf Endtemperatur.Circuit 1 is used for the actual shock cooling of the high-temperature gas in a along the flow direction of the gas first area, ■ where the solid particles contained in the gas are also separated, - circuit 2 serves for the final cooling in a second area along the flow direction of the gas to the final temperature.
Erfindungsgemäß ist die Verwendung einer solchen Vorrichtung bzw. eines solchen Verfahrens zur Kühlung von in einem Hochtemperaturrecyclingverfahren anfal- lenden Synthesegasen vorgesehen.According to the invention, the use of such a device or of such a method for cooling synthesis gases obtained in a high-temperature recycling process is provided.
Die vorteilhafte Wirkung der Erfindung besteht in der Lokalisierung der durch die Schockkühlung abgeschiedenen, festen Partikel in einem begrenzten Bereich der Kühlung. Im Zusammenhang mit der im Folgenden genannten Ausführung ist dann sogar die vollkommene Vermeidung von Verschmutzung von Wärmetauschern durch die abgeschiedenen, festen Partikel möglich.The advantageous effect of the invention is to localize the solid particles separated by the shock cooling in a limited area of the cooling. In connection with the design mentioned below, it is even possible to completely avoid contamination of heat exchangers by the separated, solid particles.
Vorzugsweise sind Quenchwärmetauscher ausschließlich im sauberen 'Kreislauf 2 angeordnet. Über diese Quenchwärmetauscher wird die im Hochtemperaturgas enthaltene Energie abgeführt. Folglich wird der Kreislauf 1, d. i. der eigentliche Quenchkreislauf, ohne Wärmetauscher ausgeführt. Eine Verschmutzung des ersten Kühlkreislaufes ist somit weitgehend ausgeschlossen.Preferably Quenchwärmetauscher are arranged solely in the clean "cycle. 2 The energy contained in the high-temperature gas is dissipated via these quench heat exchangers. Consequently, the circuit 1, ie the actual quench circuit, is carried out without a heat exchanger. Contamination of the first cooling circuit is therefore largely ruled out.
