In der Hochtemperaturverfahrenstechnik werden bei einer Vielzahl von Anwendungsfällen Rauchgase durch Zugabe von Flüssigkeiten wie zum Beispiel Wasser schockartig abgekühlt. Man spricht hierbei vom Vorgang des Quenchens, der dafür genutzte Apparat ist die sogenannte Quench.In of high temperature process engineering are used in a large number of Flue gas applications by adding liquids such as water cooled down like a shock. One speaks here of Process of quenching, for that the device used 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 Wär meenergie wird mittels Quenchwärmetauscher aus dem System abgeführt.The Water is circulated using quench pumps. Between Water inlet and outlet heated the quench water is around 10 to 30 ° C. This heat energy is generated using a quench heat exchanger dissipated from the system.
Charakteristisch für den Prozess ist, dass neben der Abkühlung des Gases auch im Gas befindliche Fremdstoffe in der Flüssigkeit abgeschieden werden.Characteristic for the Process is that in addition to cooling The gas also contains foreign substances in the liquid be deposited.
Eine Verschmutzung der Wärmetauscher, der Rohrleitungen sowie aller quenchwasserführenden Apparate ist nicht vermeidbar. Deshalb ist eine wiederholte Reinigung notwendig.A Pollution of the heat exchanger Pipelines as well as all equipment carrying quench water is not preventable. 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 Mindestmass reduziert werden können. Des Weiteren ist der Ziel der vorliegenden Erfindung eine Verwendung einer solchen Vorrichtung und eines solchen Verfahrens anzugeben.task The invention is to provide an apparatus and a method on the one hand cooling the gases can be produced with high efficiency, and secondly the Cleaning work can be reduced to a minimum. Furthermore the object of the present invention is to use such Specify device and such a method.
Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung gemäß Patentanspruch 1, ein Verfahren gemäß Patentanspruch 9 und durch eine Verwendung gemäß Patentanspruch 15 gelöst.This The object is achieved by a Device according to claim 1, a method according to claim 9 and by use according to claim 15 solved.
Demnach wird zur erfindungsgemäßen Lösung der Aufgabe der Schockkühlung des Hochtemperaturgases, die Entwicklung einer Zweistufen-Quench vorgeschlagen. In zwei entlang der Strömungsrichtung des Hochtemperaturgases nacheinander lokalisierte Stufen bzw. Bereiche des Hochtemperaturgasstromes wird die Kühlung über zwei separate Kühlkreisläufe vorgenommen. Das Quenchwasser wird demnach in zwei getrennten Kreisläufen im Umlauf gehalten.Therefore becomes the solution of the invention Abandonment of shock cooling of the high temperature gas, the development of a two-stage quench proposed. In two along the flow direction of the high temperature gas successively localized stages or areas of the high-temperature gas flow cooling is via two separate Cooling circuits made. The quench water is therefore in two separate circuits in the Kept in circulation.
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.circulation 1 is used for the actual shock cooling of the high temperature gas in a along the flow direction of the gas first Area, with the solid particles contained in the gas to be separated - circulation 2 is used for the final cooling in a along the flow direction of the gas second area to final temperature.
Erfindungsgemäß ist die Verwendung einer solchen Vorrichtung bzw. eines solchen Verfahrens zur Kühlung von in einem Hochtemperaturrecyclingverfahren anfallenden Synthesegasen vorgesehen.According to the invention Use of such a device or such a method for cooling of synthesis gases generated in a high-temperature recycling process intended.
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 The advantageous effect of the invention is the localization the one by shock cooling deposited solid particles in a limited area of the Cooling. In connection with the design mentioned below then even the complete avoidance of pollution from heat exchangers possible due to 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 are quench heat exchangers only in the clean circuit 2 arranged. About this quench heat exchanger the energy contained in the high temperature gas is dissipated. consequently the circuit 1, d. i. the actual quench cycle without heat exchangers executed. Contamination of the first cooling circuit is therefore largely excluded.
Vorzugsweise handelt es sich bei der Quenchvorrichtung um einen schlanken Apparat mit einem konzentrisch angeordneten Innenrohr, wobei das heiße Gas von oben in das Innenrohr eintritt und den Apparat von oben nach unten durchströmt. Im unteren Bereich wird das Gas durch eine Umlenkungsvorrichtung umgelenkt, durchströmt danach den äußeren Ringspalt nach oben und verlässt den Apparat am oberen Ende. Die Ab kühlung im Innenrohr erfolgt vorzugsweise von 1000°C bis 2000°C auf 95°C bis 70°C, besonders bevorzugt 85°C, und im äußeren Ringspalt von 85°C auf 70 bis 40, vorzugsweise 60°C.Preferably the quenching device is a slim device with a concentrically arranged inner tube, the hot gas from enters the inner tube at the top and the apparatus from top to bottom flows through. In the lower area, the gas is deflected deflected, flowed through then the outer annular gap up and leaves the device at the top. The cooling takes place in the inner tube preferably from 1000 ° C up to 2000 ° C to 95 ° C up to 70 ° C, particularly preferably 85 ° C., and in the outer annular gap of 85 ° C to 70 to 40, preferably 60 ° C.
In einer bevorzugten Vorrichtungsvariante wird über einen freien Überlauf vom Kreislauf 2 in den Kreislauf 1 Quenchwasser abgeführt.In A preferred device variant is a free overflow Quench water discharged from circuit 2 into circuit 1.
In einer weiteren bevorzugten Ausführung erfolgt die Niveaukontrolle der beiden, im Kreislauf 1 und Kreislauf 2 bestehenden (???) Quenchwasserstände über den Qenchwasserstand im Kreislauf 1.In a further preferred embodiment takes place the level control of the two existing in circuit 1 and circuit 2 (???) Quench water levels above the Qench water level in the circuit 1.
