Abstract
Description
Die Erfindung betrifft ein Sprühdüse zum Eindüsen von Kühl- und Waschwasser in einen Quenchraum, der von heißem staub- und schlackeführendem Vergasungsgas mit Drücken bis 10 MPa und Temperaturen bis 1.850°C beaufschlagt ist. The invention relates to a spray nozzle for injecting cooling and washing water in a quench, which is acted upon by hot dust and schlackeführendem gasification gas at pressures up to 10 MPa and temperatures up to 1850 ° C.
Die Erfindung bezieht sich ganz Allgemein auf eine Vorrichtung zur Eindüsung von Kühl- und Waschwässern in heiße und staubführende Vergasungsgase. Die Erfindung bezieht sich spezieller auf eine Technologie zur Flugstromvergasung, bei der feste und flüssige Brennstoffe mit einem freien Sauerstoff enthaltenden Vergasungsmittel unter Drücken bis 10 MPa und Temperaturen bis 1.850°C in ein H2- und CO-reiches Rohgas umgesetzt werden. Die Technologie ist ausführlich in „Die Veredelung und Umwandlung von Kohle“, herausgegeben von der deutschen wissenschaftlichen Gesellschaft für Erdöl, Ergas und Kohle e.V., Kapitel 4.4.3, GSP-Vergasung, beschrieben. Danach wird das mit Temperaturen bis 1.850°C den Reaktionsraum gemeinsam mit Flugstaub und der zu Schlacke aufgeschmolzen Brennstoffasche verlassende Rohgas in einem Quenchraum durch das Einspritzen von Wasser im Überschuss gewaschen und bis zur Wasserdampfsättigung gekühlt, was bei einem Vergasungsdruck von beispielsweise 4 MPa einer Temperatur von ca. 210°C entspricht. Die Schlacke sammelt sich im Wassersumpf des Quenchraumes und wird gemeinsam mit Schlackewasser ausgeschleust. Das Überschusswasser aus der Quenchung wird gemeinsam mit Waschwässern und anfallenden Kondensaten als Russwasser einer Abscheidung der Feststoffe unterzogen, um es im Kreislauf dem Quench- und Waschprozess wieder zuführen zu können. The invention relates generally to a device for the injection of cooling and washing waters into hot and dust-carrying gasification gases. More particularly, the invention relates to entrainment gasification technology in which solid and liquid fuels are reacted with a free oxygen-containing gasification agent at pressures of up to 10 MPa and temperatures of up to 1850 ° C. in a

Der Erfindung liegt das Problem zugrunde, eine Sprühdüse zum Eindüsen von Kühl- und Waschwasser in einen Quenchraum derart weiterzubilden, dass die Zuverlässigkeit im Betrieb steigt und die Wartungsintervalle erheblich verlängert sind. The invention is based on the problem of developing a spray nozzle for injecting cooling and washing water into a quenching chamber in such a way that the reliability increases during operation and the maintenance intervals are considerably prolonged.
Das Problem wird durch eine Sprühdüse zum Eindüsen von Kühl- und Waschwasser in einen Quenchraum
Die erfindungsgemäße Sprühdüse ist weitgehend resistent gegen ein Zusetzen durch Ablagerungen, wodurch das Serviceintervall der Sprühdüse erheblich verlängert ist. Durch die nach unten geneigte Anordnung der Sprühdüse befindet sich der Sprühkopf der Sprühdüse im Abschattungsbereich der Hülse bezüglich der von oben kommenden Schlackepartikel, was einem Zusetzen der Sprühdüse entgegenwirkt. The spray nozzle according to the invention is largely resistant to clogging by deposits, whereby the service interval of the spray nozzle is considerably extended. Due to the downwardly inclined arrangement of the spray nozzle is the spray head of the spray nozzle in Abschattungsbereich the sleeve with respect to the coming from above slag particles, which counteracts clogging of the spray nozzle.
Gemäß einer besonderen Weiterbildung der Erfindung ist der Ringraum zwischen Sprühdüse und Hülse durch ein Spülgas gespült. Diese Maßnahme wirkt zusätzlich einem Zusetzen der Sprühdüse entgegen. According to a particular embodiment of the invention, the annular space between the spray nozzle and sleeve is purged by a purge gas. This measure additionally counteracts clogging of the spray nozzle.
Gemäß einer besonderen Weiterbildung der Erfindung ist der Düsenkopf der Sprühdüse hinter dem inneren Mantel zurückgezogen angeordnet und die Hülse schließt im Wesentlichen plan mit dem inneren Mantel ab. Durch diese Maßnahme wird ein Aufwachsen von Ablagerungen auf die in den Quenchraum hineinragende Hülse weitgehend vermieden. According to a particular embodiment of the invention, the nozzle head of the spray nozzle is arranged behind the inner jacket retracted and the sleeve is substantially flush with the inner shell. By this measure, an accumulation of deposits on the projecting into the quench chamber sleeve is largely avoided.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. Advantageous developments of the invention are specified in the subclaims.
