Abstract
Description
Die vorliegende Erfindung betrifft einen statischen Mischer für eine Abgasanlage einer Brennkraftmaschine, mit einer Anzahl von Trägerelementen und Strömungsleitelementen, wobei die Trägerelemente eine Mischerebene definieren und die an die Trägerelemente angeformten Strömungsleitelemente um einen vorgegebenen Winkel gegenüber der Mischerebene geneigt sind, um die Strömung des Abgases zu beeinflussen.The The present invention relates to a static mixer for an exhaust system of an internal combustion engine, with a number of Carrier elements and flow guide elements, wherein the support elements define a mixer plane and the formed on the support elements flow guide by a predetermined angle relative to the mixer plane are inclined to influence the flow of the exhaust gas.
Zur Verminderung der Stickoxidemissionen (NOx) werden so genannte „SCR"-Verfahren zur selektiven katalytischen Reduktion eingesetzt. Dabei werden bei magerer Abgaszusammensetzung geeignete Reduktionsmittel, wie Ammoniak oder Ammoniakvorstufen zur Umwandlung der Stickoxide in das Abgas eingebracht. Durch die Umwandlung entstehen umweltfreundliche Endprodukte wie Stickstoff (N2), Kohlendioxid (CO2) und Wasser (H2O). Damit die Umwandlung besonders effektiv erfolgen kann, werden in die Abgasanlage statische Mischer eingesetzt, welche eine möglichst gute Verteilung des Reduktionsmittels in dem Abgas bewirken sollen.To reduce the emissions of nitrogen oxides (NO x) are so-called "SCR" process used for the selective catalytic reduction. This case, in a lean exhaust gas composition suitable reducing agent such as introduced ammonia or ammonia precursors for the conversion of the nitrogen oxides in the exhaust gas converting environmentally friendly final products shown. Nitrogen (N 2 ), carbon dioxide (CO 2 ) and water (H 2 O) In order for the conversion to be particularly effective, static mixers are used in the exhaust system, which are intended to achieve the best possible distribution of the reducing agent in the exhaust gas.

Vor diesem Hintergrund ist es Aufgabe der vorliegenden Erfindung, einen verbesserten statischen Mischer für eine Abgasanlage zu schaffen, der sich gegenüber dem Stand der Technik durch die Ausbildung eines gewünschten Strömungsprofils auszeichnet, welches eine besonders effektive Durchmischung des Abgases und gegebenenfalls eines zusätzlichen Hilfsmittels erlaubt. Zudem soll dieser statische Mischer auch kostengünstig herstellbar sein.In front It is an object of the present invention to provide a improved static mixer for an exhaust system create that is superior to the state of the art characterizes the formation of a desired flow profile, which is a particularly effective mixing of the exhaust gas and optionally an additional resource allowed. In addition, this should static mixer also be inexpensive to produce.
Gelöst wird die Aufgabe, indem bei dem eingangs genannten statischen Mischer die Trägerelemente radial um eine Mischerebene herum angeordnet sind und die Strömungsleitelemente flügelartig an die Trägerelemente angeformt sind und wenigstens eine schlitzartige Einkerbung aufweisen. Durch die radiale Anordnung von Trägerelementen und geneigten Strömungsleitelementen wird der ankommenden Strömung des Abgases eine drallförmige Komponente überlagert und durch die schlitzartigen Einkerbungen in den Strömungsleitelementen werden der ankommenden Abgasströmung zusätzlich noch wirbelförmige Komponenten überlagert. Darüber hinaus wird durch die Einkerbungen auch der Abgasgegendruck vor dem Mischer herabgesetzt. Diese komplexe Beeinflussung bewirkt einen besonders turbulenten Strudel im Abgas, so dass eventuell beigegebene Hilfsmittel, wie zum Beispiel Ammoniak homogen mit dem Abgas vermischt werden.Solved will do the job by adding to the static mixer mentioned above the carrier elements are arranged radially around a mixer plane are and the flow guide wing-like are formed on the support elements and at least one have slit-like notch. Due to the radial arrangement of support elements and inclined flow guide elements the incoming flow of the exhaust gas is a swirl-shaped Component superimposed and through the slot-like notches in the flow guide elements, the incoming exhaust gas flow additionally superimposed vortex-shaped components. In addition, by the notches and the exhaust back pressure lowered before the mixer. This complex influence causes a particularly turbulent vortex in the exhaust, so that eventually added aids, such as ammonia homogeneously with the Exhaust gas are mixed.
Stromab des erfindungsgemäßen Mischers lässt sich im weiteren Verlauf der Abgasanlage somit eine optimale Konvertierung der im Abgas enthaltenen Emissionen realisieren.Downstream of the mixer according to the invention in the course of the exhaust system thus an optimal conversion realize the emissions contained in the exhaust gas.
Vorteilhaft sind die Trägerelemente rotationssymmetrisch zueinander angeordnet. Dadurch ist ein gleichmäßiger Aufbau des statischen Mischers geschaffen, so dass beim Einbau des Mischers in die Abgasanlage der Brennkraftmaschine keine bestimmte Orientierung zu berücksichtigen ist.Advantageous the carrier elements are rotationally symmetrical to each other arranged. This is a uniform structure created by the static mixer, so that when installing the mixer in the exhaust system of the internal combustion engine no particular orientation to take into account.
Besonders vorteilhaft sind die Trägerelemente nahe der Mischerachse an einem Innenring befestigt und fern der Mischerachse an einem Außenring befestigt. Diese Merkmale sind aus fertigungstechnischer Hinsicht besonders einfach und kostengünstig zu realisieren. Zudem stellt diese Konstruktion speziell im Hinblick auf eventuelle Druckpulsationen innerhalb der Abgasanlage eine besonders stabile Konstruktion dar.Especially Advantageously, the support elements are close to the mixer axis attached to an inner ring and away from the mixer axis at one Attached outer ring. These features are of manufacturing technology Considered particularly simple and inexpensive to implement. In addition, this construction is special with regard to eventual Pressure pulsations within the exhaust system a particularly stable Construction dar.
Zweckmäßig sind die flügelartigen Strömungsleitelemente an wenigstens einer der beiden Stirnseiten der Trägerelemente angeformt. Somit können die geneigten Strömungsleitelemente sowohl in die Richtung der Abgasströmung als auch in die Richtung entgegen der Abgasströmung weisen. Aufgrund der Dynamik des durch die Abgasanlage strömenden Abgases ist dabei jedoch jene Variante zu bevorzugen, bei welcher die Strömungsleitelemente in die Richtung der Abgasströmung weisen.expedient are the wing-like flow guide on at least one of the two end faces of the carrier elements formed. Thus, the inclined flow guide both in the direction of the exhaust flow and in the direction have against the exhaust flow. Because of the dynamics the exhaust gas flowing through the exhaust system is thereby However, to prefer that variant in which the flow guide in have the direction of the exhaust flow.
Besonders zweckmäßig sind die an einander gegenüberliegenden Stirnseiten eines Trägerelements angeformten flügelartigen Strömungsleitelemente in zueinander entgegengesetzte Richtungen geneigt.Especially it is expedient to be at opposite ends End sides of a support member molded wing-like Flow guide inclined in opposite directions.
Ist die wenigstens eine schlitzartige Einkerbung der flügelartigen Strömungsleitelemente im Wesentlichen konzentrisch zur Mischerachse ausgebildet und bis an die angrenzende Stirnseite der Trägerelemente reichend, so ist jedes Strömungsleitelement in wenigstens zwei Teilsegmente aufgespal ten. Durch die Anzahl und Ausmaße der schlitzartigen Einkerbungen wird dabei nicht nur die wirbelförmige Komponente, sondern auch der Abgasgegendruck stromauf des statischen Mischers erheblich beeinflusst, da hierdurch kein vollflächiger Rotationsmischer dargestellt ist.is the at least one slit-like notch of the wing-like ones Flow guide substantially concentric to Mischerachse formed and up to the adjacent end of the Carrier elements reaching, so is each flow guide in at least two sub-segments aufgespal th. By the number and The dimensions of the slot-like notches will not only the vortex-shaped component, but also the exhaust back pressure upstream of the static mixer significantly affected, since this no full-surface rotary mixer is shown.
Bevorzugt sind die wenigstens zwei Teilsegmente der durch die Einkerbung aufgespalteten Strömungsleitelemente gegenüber der Mischerebene um unterschiedliche Winkel geneigt. Dies erlaubt eine unterschiedliche Ausbildung der inneren und äußeren Drallkomponente, so dass dem Strömungsprofil des Abgases auch entsprechend unterschiedliche Geschwindigkeiten aufgeprägt werden.Prefers are the at least two sub-segments of the split by the notch Flow guide with respect to the mixer plane inclined at different angles. This allows a different one Formation of the inner and outer swirl component, so that the flow profile of the exhaust gas also accordingly different speeds are imprinted.
Besonders bevorzugt sind die inneren Teilsegmente der Strömungsleitelemente um einen ersten Winkel zur Mischerebene geneigt und sind die äußeren Teilsegmente um einen zweiten Winkel zur Mischerebene geneigt, wobei der erste Winkel kleiner ist als der zweite Winkel. Diese Ausbildung vermeidet, dass der Abgasströmung zugegebene Hilfsmittel aufgrund eines zu starken Dralls im äußeren Bereich an der Wandung der Abgasanlage abgeschieden werden.Especially preferred are the inner sub-segments of the flow guide inclined at a first angle to the mixer plane and are the outer Sub-segments inclined by a second angle to the mixer plane, wherein the first angle is smaller than the second angle. This training avoids the aids added to the exhaust gas flow due to excessive swirl in the outer area be deposited on the wall of the exhaust system.
Der in der Abgasanlage einer Brennkraftmaschine angeordnete statische Mischer sollte so angeordnet sein, dass er stromab einer Einspritzanlage für ein Hilfsmittel und stromauf einer Katalysatoranlage positioniert ist. Dadurch kann die Durchmischung des Hilfsmittels und des Abgases optimal erfolgen, obgleich eine Durchmischung grundsätzlich auch dann möglich ist, wenn der statische Mischer sowohl stromauf der Einspritzanlage für das Hilfsmittel als auch stromauf der Katalysatoranlage positioniert ist.Of the arranged in the exhaust system of an internal combustion engine static Mixer should be arranged so that it is downstream of an injection system for an auxiliary and positioned upstream of a catalyst system is. This allows the mixing of the auxiliary and the exhaust gas optimally done, although a thorough mixing in principle is possible even if the static mixer both upstream the injection system for the resource as well as upstream the catalyst system is positioned.
