Description
Die Erfindung betrifft eine Vorrichtung zum Mischen zweier Fluidkomponenten. Es kann sich um gasförmige oder flüssige Komponenten handeln.The invention relates to a device for mixing two fluid components. It can be gaseous or liquid components.
Fluidkomponentenmischer sind bekannt. Beispielsweise ist aus der EP 0 303 439 A2 ein Gasmischer und -verteiler für einen Reaktor, beispielsweise einen katalytischen Reaktor bekannt. Weiterhin ist aus der GB 735 519 A ein Verfahren und eine Vorrichtung zum Mischen von Gasen bekannt, wobei die Mischung über eine relativ kleine Fläche erfolgt.Fluid component mixers are known. For example, EP 0 303 439 A2 a gas mixer and distributor for a reactor, for example a catalytic one Reactor known. Furthermore, from GB 735 519 A a method and a Apparatus for mixing gases known, the mixing over a relative small area.
Der Erfindung liegt die Aufgabe zugrunde, das Gemisch sehr homogen und dabei großflächig zu erzeugen.The invention is based, the mixture very homogeneous and the task to generate large areas.
Zur Lösung dieser Aufgabe ist die Vorrichtung zum Mischen zweier Fluidkomponenten erfindungsgemäß dadurch gekennzeichnet,
- daß eine Kammer vorgesehen ist, die durch eine Mehrzahl von im wesentlichen in einer gemeinsamen Ebene im wesentlichen parallel zueinander ausgerichteten Rohren in einen ersten und einen zweiten Raum unterteilt ist,
- daß der erste Raum der Kammer an eine Zuführungseinrichtung für die eine Fluidkomponente angeschlossen ist,
- daß die Rohre an eine Zuführungseinrichtung für die andere Fluidkomponente angeschlossen sind,
- daß zwischen benachbarten Rohren mindestens ein Abstandshalter vorgesehen ist, der erste Öffnungen für den Durchtritt des einen Fluids aus dem ersten in den zweiten Raum der Kammer bildet, und
- daß benachbarte Rohre zweite Öffnungen für den Austritt des anderen Fluids aus den Rohren in den zweiten Raum aufweisen,
- wobei die ersten und die zweiten Öffnungen einander benachbart angeordnet sind.
- that a chamber is provided which is divided into a first and a second space by a plurality of tubes which are aligned essentially parallel to one another and essentially in a common plane,
- that the first space of the chamber is connected to a feed device for the one fluid component,
- that the pipes are connected to a feed device for the other fluid component,
- that at least one spacer is provided between adjacent tubes, which forms first openings for the passage of the one fluid from the first into the second space of the chamber, and
- that adjacent pipes have second openings for the outlet of the other fluid from the pipes into the second space,
- wherein the first and second openings are arranged adjacent to each other.
Auf diese Weise entsteht ein Feld von reihenweise angeordneten Öffnungen, wobei jede Reihe ihrerseits aus drei Öffnungsreihen besteht, nämlich einer zentralen Reihe aus ersten Öffnungen und zwei flankierenden Reihen aus zweiten Öffnungen. Das Gemisch wird also auf der gesamten Fläche des Feldes gebildet, und zwar an jeder Stelle des Feldes mit gleicher Homogenität. Der Grad der Homogenität ist hoch, bedingt durch die Zuordnung der ersten zu den zweiten Öffnungen, nämlich der Flankierung einer zentralen Reihe durch zwei benachbarte äußere Reihen.In this way a field of openings arranged in rows is created, whereby each row in turn consists of three rows of openings, namely a central row of first openings and two flanking rows of second openings. The Mixture is thus formed on the entire surface of the field, on everyone Place the field with the same homogeneity. The degree of homogeneity is high, conditional by assigning the first to the second openings, namely the flanking a central row through two adjacent outer rows.
Die Vorrichtung eignet sich insbesondere zum Mischen zweier gasförmiger Komponenten. Dabei wird in Weiterbildung der Erfindung vorgeschlagen, daß die gemeinsame Ebene der Rohre im wesentlichen horizontal ausgerichtet ist, wobei der erste Raum der Kammer der untere und der zweite Raum der obere ist. Wesentliches Anwendungsgebiet sind Flächenbrenner, katalytische Reaktoren und dergleichen. Diese bilden die obere Abdeckung der Kammer und werden mit dem homogenen Gemisch großflächig beaufschlagt. Verwiesen sei beispielsweise auf katalytische Brenner, wie sie in der Brennstoffzellentechnik zur Anwendung kommen.The device is particularly suitable for mixing two gaseous components. It is proposed in a further development of the invention that the common The plane of the tubes is aligned substantially horizontally, the first Room of the chamber is the lower one and the second room is the upper one. Essential area of application are surface burners, catalytic reactors and the like. These form the top cover of the chamber and are homogeneous with the Mixture applied to a large area. For example, refer to catalytic Burners such as those used in fuel cell technology.
Besonders günstige Mischergebnisse werden erzielt, wenn die aus den zwischen benachbarten Rohren befindlichen drei Öffnungsreihen austretenden Fluidstrahlen einander kreuzen und sich gegenseitig verwirbeln. Die Verwirbelung kann noch dadurch gesteigert werden, daß man die Öffnungen in Rohrlängsrichtung gegeneinander versetzt.Particularly favorable mixing results are achieved if those between the neighboring ones Tubes located three rows of openings emerging fluid jets each other cross and swirl each other. The turbulence can still be caused by this be increased that the openings in the pipe longitudinal direction against each other added.
Dabei können die Fluidkomponenten aus den Öffnungen ausgeblasen oder herausgesaugt werden.The fluid components can be blown out or sucked out of the openings become.
Zwischen benachbarten Rohren können einzelne Abstandshalter-Elemente angeordnet werden, zwischen denen sich die ersten Öffnungen bilden. Vorteilhafter ist es, einen streifenförmigen Abstandshalter zu verwenden, der mit den ersten Öffnungen versehen ist. In jedem Falle empfiehlt es sich, letztere, wie auch die zweiten Öffnungen, schlitzförmig auszubilden. Die Abstandshalter stabilisieren die gesamte Rohrmatrix, so daß Wärmespannungen gleichmäßig über der Kammer verteilt werden.Individual spacer elements can be arranged between adjacent tubes between which the first openings are formed. It is more advantageous to use a strip-shaped spacer that has the first openings is provided. In any case, it is recommended that the latter, like the second openings, to be slit-shaped. The spacers stabilize the entire tube matrix, so that thermal stresses are evenly distributed over the chamber.
In wesentlicher Weiterbildung der Erfindung wird vorgeschlagen, daß die einander gegenüberliegenden Wände benachbarter Rohre eben ausgebildet sind und, ausgehend vom zugehörigen Abstandshalter, in den unteren Raum der Kammer hinein divergieren. Dies führt auf der Zuströmseite des Abstandshalters, d. h., auf der Zuströmseite der ersten Öffnungen zu einer düsenförmigen Gestaltung, in deren engstem Querschnitt die ersten Öffnungen angeordnet sind. Die Strömung der einen Fluidkomponente wird also beschleunigt. Direkt hinter dem engsten Querschnitt münden die in den Rohren ausgebildeten zweiten Öffnungen. Der Mischeffekt ist also optimal.In an essential further development of the invention it is proposed that the one another opposite walls of adjacent pipes are flat and starting from the associated spacer, into the lower chamber diverge. This leads to the upstream side of the spacer, i.e. that is, on the upstream side the first openings to a nozzle-shaped design, in its narrowest Cross section the first openings are arranged. The flow of some Fluid component is thus accelerated. Right behind the narrowest cross section open the second openings formed in the tubes. So the blending effect is optimal.
Die Anordnung wird so getroffen, daß die beiden Fluidkomponenten an der Mischstelle vorzugsweise zumindest angenähert gleiche Strömungsgeschwindigkeiten aufweisen. Das Mischungsverhältnis wird eingestellt durch das Flächenverhältnis der ersten zu den zweiten Öffnungen, und zwar unter Berücksichtigung von Dichte und Temperatur der Fluidkomponenten.The arrangement is such that the two fluid components at the mixing point preferably at least approximately the same flow velocities exhibit. The mixing ratio is set by the area ratio of the first to the second openings, taking into account density and Temperature of the fluid components.
Die oberhalb jedes Abstandshalters befindliche Mischzone wird dadurch optimiert, daß die einander gegenüberliegenden Wände benachbarter Rohre eben ausgebildet sind und, ausgehend vom zugehörigen Abstandshalter, in den oberen Raum der Kammer hinein divergieren.The mixing zone above each spacer is optimized that the opposite walls of adjacent pipes are flat are and, starting from the associated spacer, in the upper room of the The chamber diverge.
Aus konstruktiven Gründen ist es vorteilhaft, den Querschnitt der Rohre im wesentlichen vier- oder sechseckig auszubilden.For design reasons, it is advantageous to use the cross-section of the tubes essentially to form square or hexagonal.
Weitere vorteilhafte Merkmale ergeben sich aus den Unteransprüchen, und zwar im Zusammenhang mit einer Optimierung des Mischvorgangs durch entsprechende gegenseitige Zuordnung der Öffnungen.Further advantageous features emerge from the subclaims, namely in In connection with an optimization of the mixing process by corresponding mutual Allocation of openings.
Eine Weiterentwicklung besteht darin, daß die an die Rohre angeschlossene Zufuhreinrichtung als Vormischkammer ausgebildet ist, die mittels einer Wand, die eine Vielzahl von Austrittsöffnungen für Prallstrahlen aufweist, in einen ersten und einen zweiten Mischraum unterteilt ist, daß an den ersten Raum eine Zufuhrleitung für einen ersten Fluidstrom und an den zweiten Mischraum eine Zufuhrleitung für einen zweiten Fluidstrom angeschlossen ist und daß der zweite Mischraum eine an die Kammer angeschlossene Auslaßöffnung für das Fluidgemisch aufweist.A further development is that the feed device connected to the pipes is designed as a premixing chamber, which by means of a wall, the one Has a plurality of outlet openings for impact jets, in a first and a second mixing room is divided into that a supply line for a to the first room first fluid flow and to the second mixing space a supply line for a second fluid flow is connected and that the second mixing chamber one to the Has chamber connected outlet opening for the fluid mixture.
Vorzugsweise sind die Austrittsöffnungen als rohrförmigen Verlängerungen ausgebildet, die an ihrem Ende eine Prallplatte aufweisen. The outlet openings are preferably designed as tubular extensions, which have a baffle plate at their end.
Nach einem weiteren vorteilhaften Merkmal der Erfindung ist die Vorrichtung dadurch gekennzeichnet, daß die Vormischkammer und die Kammer eine Baueinheit bilden und daß sich die Vormischkammer und deren Auslaßöffnung über die Länge der Kammer erstrecken.According to a further advantageous feature of the invention, the device is thereby characterized in that the premixing chamber and the chamber form a structural unit and that the pre-mixing chamber and its outlet opening over the length of the Extend chamber.

Zusammenhang mit der beiliegenden Zeichnung näher erläutert. Die Zeichnung zeigt

Nach Figur 1 weist die Vorrichtung eine Kammer 1 auf, die von einer Mehrzahl von
Rohren 2 in einen unteren Raum 3 und einen oberen Raum 4 unterteilt wird. In den
unteren Raum 3 wird ein wasserstoffreiches Gas eingeleitet, welches aus einer
Brennstoffzelle kommt. Die Rohre 2 werden mit einem Gemisch aus Luft und Rezirkulationsgas
der Brennstoffzelle beaufschlagt. Die Vorrichtung dient dazu, die beiden
Fluidkomponenten Gas und Rezirkulationsgas homogen miteinander zu mischen,
und zwar unter Erzeugung eines großflächigen Gemisches, welches einem
Katalysatorbrenner zugeführt wird. Dieser bildet den oberen Abschluß der Kammer 1.According to FIG. 1, the device has a chamber 1, which consists of a plurality of

durch einen Abstandshalter 5 miteinander verbunden. Der Abstandshalter 5 weist
erste Öffnungen 6 auf .Figure 2 shows two
Diejenigen Wände 7 der benachbarten Rohre 2, die sich vom Abstandshalter 5 aus
nach unten erstrecken, divergieren in den unteren Raum 3 hinein. Es ergibt sich also
eine düsenförmige Gestaltung, die das wasserstoffreiche Gas in Richtung auf den
Abstandshalter 5 beschleunigt. Those
Diejenigen Wände 8 der benachbarten Rohre 2, die sich vom Abstandshalter 5 aus
nach oben erstrecken, divergieren in den oberen Raum 4 hinein. Sie bilden dadurch
oberhalb des Abstandshalters 5 eine Mischzone. In dieser Mischzone münden zweite
Öffnungen 9, die direkt benachbart zu den ersten Öffnungen 6 in den Wänden 8 der
beiden benachbarten Rohre 2 ausgebildet sind. Es entstehen also drei Fluidströme,
die sich an einer Mischstelle direkt oberhalb des Abstandshalters 5 kreuzen. Die
Durchmischung ist entsprechend intensiv, so daß sich auf großer Fläche ein sehr
homogenes Gemisch ergibt.Those
Figur 3 zeigt die Anordnung nach Figur 2 in Draufsicht. Die im Abstandshalter 5 ausgebildete
Reihe der ersten Öffnungen 6 wird beidseitig von je einer Reihe der zweiten
Öffnungen 9 flankiert. Sämtliche Öffnungen sind schlitzförmig ausgebildet. Außerdem
sind die Öffnungen sämtlicher drei Öffnungsreihen in Rohrlängsrichtung gegeneinander
versetzt. Dabei ist die Anordnung so getroffen, daß die zweiten Öffnungen
9 der einen äußeren Reihe die zweiten Öffnungen 9 der anderen äußeren
Reihe überlappen, und zwar unter gleichzeitiger Überlappung der ersten Öffnungen 6
in der mittleren Reihe. Die Anordnung ist symmetrisch getroffen. Es wurde gefunden,
daß auf diese Weise optimale Mischergebnisse erzielbar sind, und zwar über der
gesamten Fläche der Kammer 1.Figure 3 shows the arrangement of Figure 2 in plan view. The trained in the
In Figur 4 ist eine Vormischkammer 10 schematisch dargestellt. Ein erster Mischraum
11 ist von einem zweiten Mischraum 12 durch eine Wand 13 getrennt. Dem erstem
Mischraum 11 wird Luft über eine Luftzufuhrleitung 14 zugeführt. Der zweite
Mischraum 12 ist über eine Rezirkulationsgas-Zufuhrleitung 15 mit der nicht dargestellten
Brennstoffzelle verbunden.A premixing
Die Wand 13 weist eine Vielzahl von Austrittsöffnungen 16 in Form von rohrartigen
Verlängerungen auf, die in Reihen neben- und hintereinander im wesentlichen über
die gesamte Fläche der Vormischkammer 10 angeordnet sind. Die rohrartigen Verlängerungen
16 weisen an ihrem offenen Ende je eine Prallplatte 17 auf. Die Luft trifft
senkrecht auf die Prallplatten und tritt in einem im wesentlichen rechten Winkel in
den zweiten Raum 12 ein, in dem sich das Rezirkulationsgas befindet. Auf diese
Weise werden die beiden nicht brennbaren Gase homogen und großflächig
miteinander gemischt. Die relativ kalte Frischluft wird dabei durch das
Rezirkulationsgas, das eine Temperatur von etwa 650 °C aufweist, aufgewärmt. Die
Lufttemperatur wird etwa auf die Betriebstemperatur des Katalysatorbrenners
angehoben.The

Die Vormischkammer 10 und die Kammer 1 bilden eine Baueinheit. Die Vormischkammer

Länge der Kammer 1. Damit wird das Gasgemisch aus der Vormischkammer sämtlichen
Rohren 2 der Kammer 1 zugeführt.The premixing
Im Rahmen der Erfindung sind durchaus Abwandlungsmöglichkeiten gegeben. So
können die Rohre, abweichend von der dargestellten sechseckigen Form, einen
viereckigen Querschnitt aufweisen. Eine fünfeckige Form mit einer oberen Spitze und
einem unteren horizontalen Abschluß ist gleichermaßen möglich. Anstelle
schlitzförmiger Öffnungen kann mit kreisförmigen oder ovalen Öffnungen gearbeitet
werden. Auch lassen sich unterschiedliche Öffnungsformen miteinander kombinieren.
Der untere Raum kann sich durchgehend unterhalb der Rohrmatrix erstrecken oder
in einzelne Abschnitte unterteilt sein, die in Rohrlängsrichtung verlaufen. Auch besteht
die Möglichkeit, den oberen Raum 4 in Sektoren zu unterteilen, wobei allerdings
das Merkmal der Großflächigkeit erhalten bleibt.In the context of the invention, there are quite a number of possible modifications. So
the tubes, unlike the hexagonal shape shown, one
have a square cross-section. A pentagonal shape with an upper tip and
a lower horizontal conclusion is equally possible. Instead of
slot-shaped openings can be worked with circular or oval openings
become. Different opening shapes can also be combined.
The lower space can extend continuously below the tube matrix or
be divided into individual sections that run in the longitudinal direction of the pipe. Also exists
the possibility of dividing the
Die erzielbare Homogenität und Großflächigkeit des erzeugten Gemisches läßt sehr gleichmäßige Verbrennungsvorgänge und katalytische oder nicht-katalytische Reaktionen zu.The achievable homogeneity and large area of the mixture produced leaves a lot smooth combustion processes and catalytic or non-catalytic reactions to.
Bei Anwendung auf einen Flächenbrenner ist die im wesentlichen horizontale Ausrichtung der Kammer besonders vorteilhaft. Bei sonstigen Reaktionen kann die Orientierung der Kammer nach Bedarf geändert werden.When applied to a surface burner, the orientation is essentially horizontal the chamber particularly advantageous. For other reactions, the orientation can the chamber can be changed as needed.
