Abstract
Description
Die Erfindung betrifft einen Mischer für die Mischung von Gasen und anderen Newtonschen Flüssigkeiten, mit einem Strömungskanal und darin angeordneten, die Strömung beeinflussenden Einbauflächen, wobei die Einbauflächen wirbelerzeugende Flächen mit frei umströmten, gegen die Strömung gerichteten Vorderkanten sind, deren Verlauf sowohl eine in Hauptströmungsrichtung des Gases als auch eine quer hierzu verlaufende Komponente aufweist.The invention relates to a mixer for mixing gases and others Newtonian liquids, with a flow channel and arranged therein, the installation surfaces influencing the flow, the installation surfaces generating vortex Surfaces with freely flowing front edges directed against the flow are, the course of which is both in the main flow direction of the gas and also has a transverse component.
Zum Mischen von Gas- oder Flüssigkeitsströmungen in Rohrleitungen oder Kanälen benötigt man bei turbulenter Strömung Mischlängen vom 15 bis 100-fachen des Kanaldurchmessers. Mittels geeigneter statischer Mischer in Gestalt von Einbaukörpern läßt sich diese Mischstrecke deutlich verkürzen. Es muß jedoch bei den meisten herkömmlich angewendeten Systemen ein hoher Druckverlust insbesondere dann in Kauf genommen werden, wenn hohe Anforderungen an die Homogenität der sich einstellenden Mischung gestellt werden. Viele der herkömmlichen Mischsysteme sind außerdem auf einfache Geometrien beschränkt, z.B. auf zylindrische Rohre oder quadratische Kanäle, und lassen sich nicht bei Großanlagen und komplizierten Mischkammersystemen anwenden.For mixing gas or liquid flows in pipes or In turbulent flows, channels are required to have mixed lengths of 15 to 100 times of the channel diameter. Using a suitable static mixer in shape this mixing distance can be shortened significantly by built-in bodies. It must however, a high for most conventionally used systems Pressure loss can be accepted especially when high Requirements for the homogeneity of the resulting mixture become. Many of the conventional mixing systems are also simple Geometries limited, e.g. on cylindrical tubes or square channels, and cannot be used in large systems and complicated mixing chamber systems apply.
Aus der DE 29 11 873 C2 ist ein statischer Mischer bekannt, bei dem die Einbauten aus schräg angeströmten, deltaförmigen oder kreisscheibenförmigen Flächen bestehen, an deren Vorderkanten Wirbel entstehen. Die so gebildeten stationären und stabilen Wirbelsysteme wirken weit in den Strömungsnachlauf hinein, die zu mischenden Komponenten werden schichtenförmig eingerollt, was zu einer schnellen Vermischung bei sehr geringen Druckverlusten führt. Diese sogenannten "Wirbeleinbauflächen" haben sich wegen der erzielbaren kurzen Mischstrecke in der Praxis bewährt.A static mixer is known from DE 29 11 873 C2, in which the internals from obliquely flowed, delta-shaped or circular disc-shaped There are surfaces with vortexes on the front edges. The so educated stationary and stable vortex systems have a large effect on the wake into it, the components to be mixed are rolled up in layers, what leads to rapid mixing with very low pressure drops. This So-called "vortex installation areas" have become short because of the achievable Mixing line proven in practice.
Der Erfindung liegt die Aufgabe zugrunde, einen Mischer für die Mischung von Gasen und anderen Newtonschen Flüssigkeiten zu schaffen, der eine schnelle Vermischung bei nochmals kürzerer Mischstrecke bewirkt.The invention has for its object a mixer for the mixture of gases and other Newtonian liquids to create a fast Mixing causes the mixing section to be even shorter.
Zur Lösung dieser Aufgabe wird bei einem Mischer mit den eingangs genannten Merkmalen vorgeschlagen, daß mehrere gleichartige Einbauflächen in einer Reihe im wesentlichen quer zur Hauptströmungsrichtung angeordnet sind, und daß sich aneinander benachbarte Einbauflächen in Bezug auf die Hauptströmungsrichtung teilweise überdecken.To solve this problem, a mixer with the aforementioned Features proposed that several similar installation areas in a row is arranged essentially transversely to the main flow direction, and that mutually adjacent installation surfaces with respect to the main flow direction partially cover.
Ein solchermaßen ausgebildeter Mischer ermöglicht eine besonders schnelle Durchmischung der Strömung bei sehr kurzer Mischstrecke. Die Durchmischung hat zur Folge, daß die Profile des hindurchgeführten Gas- und/oder Flüssigkeitsstromes vergleichmäßigt werden, wobei Leistungseinbußen vermieden werden. Trotz der Bildung ausgedehnter und stabiler Wirbel hat die erfindungsgemäße Wirbeleinbaufläche einen verhältnismäßig geringen Strömungswiderstand, da sie nicht mit ihrer gesamten Oberfläche als Leitfläche wirkt, sondern mit ihren vorderen Kanten statische Wirbelfelder erzeugt, die sich in Strömungsrichtung selbsttätig erweitern, ohne daß für diese Erweiterung zusätzliche Einbauten oder Leitflächen erforderlich wären. Es ergibt sich zumindest durch die erfindungsgemäßen, einander in Bezug auf die Strömungsrichtung teilweise überdeckenden Wirbeleinbauflächen eine verlustarme und wirkungsvolle Durchmischung auf kurzer Mischstrecke.A mixer designed in this way enables a particularly fast Mixing of the flow with a very short mixing section. The mixing has the consequence that the profiles of the gas and / or Liquid flow can be evened out, thereby reducing performance become. Despite the formation of extensive and stable eddies, the Vortex installation surface according to the invention a relatively small Flow resistance, since it is not with its entire surface as a guide surface acts, but with its front edges creates static vortex fields, which are in Expand flow direction automatically, without this for this extension additional installations or baffles would be required. It follows at least through the invention, each other in relation to the Partially overlapping vortex installation areas with low flow and effective mixing on a short mixing section.
Eine bevorzugte Weiterbildung des Mischers ist gekennzeichnet durch eine im Abstand hinter der Reihe angeordnete weitere Reihe von Einbauflächen, wobei die Anstellwinkel der Einbauflächen der weiteren Reihe entgegengesetzt zu den Anstellwinkeln der Einbauflächen der ersten Reihe sind. Durch eine solche Gestaltung des Mischers läßt sich zusätzlich zu dem Mischeffekt eine Vergleichmäßigung des Geschwindigkeitsprofiles über den Querschnitt des Strömungskanals erzielen. A preferred development of the mixer is characterized by a distance another row of installation surfaces arranged behind the row, the Angle of attack of the installation surfaces of the other row opposite to the angle of attack of the installation areas are in the first row. With such a design the mixer can be evened out in addition to the mixing effect of the velocity profile across the cross-section of the flow channel.
Der Anstellwinkel der Einbauflächen in Bezug auf die Hauptströmungsrichtung beträgt vorzugsweise zwischen 40° und 80°, vorzugsweise 60°.The angle of attack of the installation surfaces in relation to the main flow direction is preferably between 40 ° and 80 °, preferably 60 °.
In weiterer Ausgestaltung des Mischers wird vorgeschlagen, daß der Strömungskanal einen im wesentlichen rechteckförmigen Querschnitt mit einem Verhältnis von Breite zu Dicke von B/D ≥ 2 aufweist, wobei die durch die Einbauflächen definierte Reihe sich in Richtung der Breite erstreckt.In a further embodiment of the mixer it is proposed that the flow channel a substantially rectangular cross-section with a ratio from width to thickness of B / D ≥ 2, the one defined by the installation surfaces Row extends in the width direction.
Auf der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemäßen Mischers
dargestellt, und zwar zeigen
Figur 1 zeigt im Längsschnitt einen sich bei 1 verengenden Strömungskanal von rechteckförmigem Querschnitt. Der Strömungskanal wird von einem im homogenen Gas- oder Flüssigkeitsgemisch durchströmt. Unter Gasen und Flüssigkeiten sind hier alle so genannten "Newtonschen Flüssigkeiten" zu verstehen, d.h. einschließlich solcher Fluide, die sich in ihren strömungstechnischen Eigenschaften vergleichbar den Gasen verhalten.FIG. 1 shows in longitudinal section a flow channel narrowing at 1 rectangular cross-section. The flow channel is from a homogeneous Flows through gas or liquid mixture. Under gases and liquids all so-called "Newtonian liquids" are to be understood here, i.e. including such fluids, which differ in their fluidic properties behave comparable to the gases.
In Figur 2 ist der Strömungskanal einschließlich seiner Breite B und seiner Dicke D im Querschnitt dargestellt. Das Verhältnis der Breite B zur Dicke D sollte vorzugsweise B/D ≥ 2 betragen.In Figure 2, the flow channel including its width B and its thickness D shown in cross section. The ratio of width B to thickness D should preferably be B / D ≥ 2.
Figur 2 läßt ebenso wie Figur 1 erkennen, daß in dem Strömungskanal in Reihe
zueinander Einbauflächen 2 angeordnet sind. Beim Ausführungsbeispiel wird die
Reihe durch insgesamt vier Einbauflächen 2 gebildet. Die Einbauflächen 2 jeder
Reihe, die sich im wesentlichen quer zur Hauptströmungsrichtung 3 erstreckt, sind
gleichartig gestaltet mit vorzugsweise jeweils demselben Anstellwinkel α zur
Hauptströmungsrichtung 3. Der Anstellwinkel α zur Hauptströmungsrichtung 3 beträgt
zwischen 40° und 80°, vorzugsweise 60°. Figure 2 shows just like Figure 1 that in the flow channel in
Die frei umströmten, gegen die Strömung gerichteten Vorderkanten 4 der beim
Ausführungsbeispiel kreisscheibenförmig gestalteten Einbauflächen 2 weisen
sowohl eine in Hauptströmungsrichtung, als auch eine quer hierzu verlaufende
Komponente auf. Da ferner jede Einbaufläche 2 unter einem spitzen Winkel zu der
Hauptströmungsrichtung 3 in dem Strömungskanal angeordnet ist, entstehen an
jeder Vorderkante 4 der Einbauflächen 2 Wirbelfelder, welche sich stromabwärts
kreiskegelförmig ausbreiten. Dabei wälzen sich die einzelnen Wirbel nach innen
auf die Rückseite der Einbaufläche 2 ab. Die an den einzelnen Vorderkanten 4
gebildeten Wirbel verhalten sich weitgehend statisch, verändern daher ihre Lage
nicht. Jedes Wirbelfeld bildet durch seine Rotation eine Strömungskomponente
quer zur Hauptströmungsrichtung des Gases, die durch den damit verbundenen
Impulsaustausch quer zur Strömungsrichtung eine gute Vermischung des Gasgemisches
zur Folge hat. Verstärkt wird die Vermischung noch durch die besonders
kompakte Anordnung der Einbauflächen 2 jeder Reihe, in dem sich einander benachbarte
Einbauflächen 2 in Bezug auf die Hauptströmungsrichtung 3 teilweise
überdecken. Diese Überdeckung ist in Figur 2 mit dem Bezugszeichen 5 bezeichnet
und schraffiert eingezeichnet.The freely flowing, against the
In Figur 1 ist mit v1 das Geschwindigkeitsprofil der Gasströmung beim Eintritt in die
Mischstrecke bezeichnet. Dieses Geschwindigkeitsprofil ist, etwa aufgrund einer
vorangehenden Umlenkung der Gasströmung, ungleichmäßig. Wird einer ersten
Reihe 6 von Einbauflächen 2 eine zweite Reihe 7 von Einbauflächen 2 nachgeordnet,
und sind die Anstellwinkel α' der Einbauflächen der zweiten Reihe 7 entgegengesetzt
zu den Anstellwinkeln α der Einbauflächen der ersten Reihe 6, läßt
sich beim Austritt aus der Mischstrecke eine Vergleichmäßigung des Geschwindigkeitsprofils
erzielen, wie dies in Figur 1 mit dem Geschwindigkeitsprofil v2
eingetragen ist.In Figure 1, v 1 denotes the velocity profile of the gas flow as it enters the mixing section. This speed profile is uneven, for example due to a previous deflection of the gas flow. If a
Beim Ausführungsbeispiel sind die Einbauflächen 2 jeweils als runde Scheiben
gestaltet. In gleicher Weise können jedoch als Wirbeleinbauflächen auch Scheiben
mit deltaförmiger bzw. dreieckiger Grundform verwendet werden, oder elliptische
oder parabelförmige Scheiben. Auch solche Scheiben besitzen symmetrisch und
jeweils schräg zur Mittelebene angeordnete Vorderkanten, wie sie für das
Entstehen von Vorderkantenwirbeln entscheidend sind. In the exemplary embodiment, the
