Abstract
Description
Die Erfindung betrifft eine Doppeldrallsprühdüse mit zwei Drallkammern zu Erzeugung von Sprühstrahlen mit entgegengesetztem Drall sowie mit einem gemeinsamen Zuströmkanal, der in einer Mittelebene zwischen den Drallkammern verläuft und jeweils tangential in die Drallkammern mündet.The invention relates to a Doppeldrallsprühdüse with two swirl chambers for generating spray with opposite spin as well as with a common inflow channel, which is in a median plane between the swirl chambers and each tangent in the swirl chambers empties.
Eine Doppeldrallsprühdüse gemäß dem Oberbegriff des Anspruchs 1 ist aus dem Dokument FR 882 080 bekannt.
Düsen dieser Art werden insbesondere, wie auch andere Doppeldrallsprühdüsen
nach der DE 197 58 526 A1, vorwiegend für sogenannte
Gaswäscher verwendet, bei denen eine Waschflüssigkeit über eine
Vielzahl von Sprühdüsen im Gasstrom möglichst gleichmäßig verteilt
über den Querschnitt eingeführt wird. Solche Gaswäscher können beispielsweise
Rauchgasreinigungsanlagen sein, in denen saure Rauchgasbestandteile
wie Schwefeldioxid, Chlor oder Fluorwasserstoff sowie
in geringerem Umfang auch Rauchgasstaub durch Verwendung entsprechender
Waschflüssigkeiten abgeschieden werden. Der Vorteil der
eingangs erwähnten Doppeldralldüsen ist es dabei, dass sich die Drallwirkung
der eingespeisten Waschflüssigkeit gegenseitig aufhebt, so
dass sich eine unerwünschte Beeinflussung der Strömung im Gaswäscher
vermeiden lässt. Dies führt zu einem höheren Wirkungsgrad.A double-twist spray nozzle according to the preamble of
Die Düsenbestückung in solchen Gaswäschern ist auf mehrere Ebenen verteilt, wobei das Gas in den Gaswäschern in der Regel von unten nach oben strömt und das zerstäubte Medium nach unten, also gegen die Gasströmung fällt. Im unteren Bereich werden die vorher erwähnten Doppeldrallsprühdüsen nach der DE 100 33 781 C1 eingesetzt, während im oberen Bereich nur nach einer Seite, also nach unten, sprühende Exzenterdüsen vorgesehen werden, um zu vermeiden, dass in den am oberen Ende von Gaswäschern, insbesondere Rauchgasentschwefelungsanlagen vorgesehenen Tropfenabscheider gesprüht wird.The nozzle assembly in such scrubbers is on several levels distributed, with the gas in the scrubbers usually from below flows upward and the atomized medium down, ie against the gas flow drops. In the lower area are the previously mentioned Double-twist spray nozzles according to DE 100 33 781 C1, while in the upper area only to one side, that is, down, spraying Eccentric nozzles be provided to avoid being in the top End of scrubbers, especially flue gas desulphurisation plants sprayed droplet separator is sprayed.
Solche Exzenterdüsen weisen in der Regel folgende Nachteile auf: Da oft der gleiche Volumenstrom, wie bei den Doppeldrallsprühdüsen im unteren Bereich gewünscht ist, muss dieser nun durch eine Drallkammer (Mundstück) versprüht werden; dadurch vergröbert sich das Tropfenspektrum, welches sich nachteilig auf den Prozess auswirken kann. Will man das Tropfenspektrum konstant halten und halbiert daher den Volumenstrom pro Düse, so muss man doppelt so viele Düsen platzieren, welches zu hohen Kosten (Befestigungsmittel, Montage, Rohrstutzen) führen kann. Da die Drallrichtung aller Exzenterdüsen gleichgerichtet ist, prägt sich ein Drall auf den Gasstrom aus, der sich - wie oben angedeutet - negativ auf die Auswaschung auswirken kann.Such eccentric nozzles generally have the following disadvantages: Da often the same volume flow as in the double-jet spray nozzles in lower range is desired, this must now by a swirl chamber (Mouthpiece) to be sprayed; this causes the droplet spectrum to coarsen, which can adversely affect the process. Want keep the drop spectrum constant and therefore halve the volume flow per nozzle, so you have to place twice as many nozzles, which at high cost (fasteners, mounting, pipe socket) can lead. Since the twisting direction of all eccentric nozzles is rectified, a spin is formed on the gas flow, which - as indicated above - can negatively affect the leaching.
Es ist die Aufgabe der vorliegenden Erfindung, eine Doppeldrallsprühdüse der eingangs genannten Art so auszubilden, dass ein Sprühstrahl trotz Drallaufhebung nur nach einer Seite möglich ist. It is the object of the present invention to provide a double-twist spray nozzle of the type mentioned above in such a way that a spray despite swirl cancellation only to one side is possible.
Zur Lösung dieser Aufgabe wird vorgesehen, dass beide Drallkammern nach der gleichen Seite hin offen sind. Überraschenderweise hat sich dabei gezeigt, dass die sich in diesem Fall wegen des gemeinsamen Zuströmkanals der nebeneinander liegenden Drallkammern schon kurz nach dem Austritt gegenseitig überlappenden Sprühstrahlen zu keiner nachteiligen Ausbildung des entstehenden Sprühfächers führen. Da die Tropfen der direkt benachbart entstehenden Sprühkegel durch den geringen Abstand der Drallkammern quasi ungebremst aufeinander treffen, führt die entgegengesetzt gerichtete Radialgeschwindigkeit der Tropfen derart zu einem Stoß, dass die Tropfen aufplatzen und hierdurch das Tropfenspektrum sich verfeinert. Dieser Effekt ist zwar bei traditionell angeordneten Düsen mit einem Abstand von 700 - 1200 mm zueinander auch vorhanden, jedoch aufgrund der dort durch den Luftwiderstand gebremsten Radialgeschwindigkeit nicht mehr so ausgeprägt. Durch die Erfindung entsteht daher ein Tropfenspektrum, das zu einem verbesserten Wirkungsgrad beiträgt. Da die Drallräume selber nur für den halben Volumenstrom ausgelegt werden müssen, können die Baulänge und damit auch die auf die Düsenverbindung wirkenden Momente reduziert werden.To solve this problem, it is provided that both swirl chambers are open to the same side. Surprisingly, it has become thereby showing that in this case because of the common Inflow channels of the adjacent swirl chambers already short after exiting mutually overlapping sprays to none lead to adverse development of the resulting Sprühfächers. Because the Drops of directly adjacent spray cone through the small Distance of the swirl chambers quasi unopposed, leads the oppositely directed radial velocity of the drops so to a shock, that the drops burst and thereby the Drop spectrum refines. This effect is traditional arranged nozzles with a distance of 700 - 1200 mm to each other also present, but due to the air resistance there slowed radial speed is less pronounced. By the The invention therefore produces a droplet spectrum which leads to an improved Efficiency contributes. Since the twist chambers themselves only for half Volume flow can be designed, the overall length and so that also reduces the forces acting on the nozzle connection moments become.
In Weiterbildung der Erfindung können die Achsen der Drallkammern in einem Winkel zueinander verlaufen, der sich zu den Austrittsseiten hin öffnet. Diese Ausgestaltung ermöglicht eine Vergrößerung der von den Sprühstrahlen abgedeckten Fläche. Die Gefahr, dass unbehandelte Gassträhnen durch den Wäscher gelangen, ist somit reduziert. Die neue Doppeldrallsprühdüse baut sehr kompakt und ist wirkungsvoll. Es hat sich gezeigt, dass dann, wenn der Einstellwinkel der Achsen der Drallkammern etwa 20° beträgt, eine besonders vorteilhafte Sprühstrahlausbildung erreicht werden kann.In a further development of the invention, the axes of the swirl chambers in at an angle to each other, towards the exit sides opens. This embodiment allows an enlargement of the Spraying covered area. The danger of being untreated Gas strands pass through the scrubber, is thus reduced. The new Double vortex spray nozzle is very compact and effective. It has shown that when the setting angle of the axes of the swirl chambers about 20 °, a particularly advantageous spray jet training can be achieved.

Die Figuren 1 bis 3 lassen erkennen, dass die neue Doppeldrallsprühdüse
ein kompaktes Gehäuse 1 mit einem Anschlussstutzen 2 besitzt,
der außen mit einem Anschlussgewinde 3 versehen ist, das mit einer
Anschlussmutter eines nicht gezeigten Zuflussrohres verschraubbar ist.
Das Gehäuse 1 umschließt zwei spiegelsymmetrisch zu der aus Fig. 2
ersichtlichen Mittelebene 4 ausgebildete Drallkammern 5 und 6, die jeweils
in trompetenartig ausgebildete Austrittsöffnungen 5a, 6a übergehen.
Die Achsen 7 bzw. 8 der Drallkammern 5 und 6 sind gegeneinander
unter einem Winkel α geneigt, der beim Ausführungsbeispiel 20° beträgt.Figures 1 to 3 show that the new double-twist spray nozzle
has a
Wie die Fig. 5 zeigt, geht der Strömungskanal 10 des Anschlussstutzens
2 ohne nennenswerte Querschnittsverengung in die beiden Drallkammern
5 und 6 über, die beide nach der gleichen Seite hin offen sind. Der
durch den Anschlussstutzen 2 zugeführte Strahl des verwendeten flüssigen
Mediums - das je nach Anwendungsfall für den betreffenden
Gaswäscher ausgewählt wird - trifft auf die gegen seine Strömungsrichtung
weisende Schneide 9 auf. Der Strahl wird daher in zwei Teile zerlegt,
von denen einer rechtsherum durch die Drallkammer 6 und der andere
linksherum in die Drallkammer 5 eingeführt wird, von wo aus dann
der Sprühstrahlaustritt in Form eines Sprühkegels nach der gleichen
Seite erfolgt. Der Strömungskanal 10 geht auf der von der Schneide 9
abgewandten Seite hinter einer Kante 11 in die jeweilige Drallkammer 5
und 6 über, er bildet eine Verschneidung mit der zugeordneten Drallkammer.

geneigt sind, lässt sich die Größe des Überlappungsbereiches beider
Sprühkegel beeinflussen und es hat sich gezeigt, dass bei einem
gewählten Winkel α von etwa 20° eine besonders gute Tropfenverteilung
in dem Doppelsprühstrahl auftritt. Durch die Neigung der Achsen gegeneinander
wird auch der gesamte Sprühstrahlbereich vergrößert, so
dass auch der Kontaktbereich mit dem zu reinigenden Gas größer wird.Since the two
