Abstract
Ein Abgasreinigungselement mit einem Gehäuse (2) und einem in das Gehäuse (2) eingesetzten Monolithen (3) weist eine zwischen Gehäuse (2) und Monolith (3) angeordnete Matte (4) auf, die den Monolithen (3) in dem Gehäuse (2) fixiert.

Description
Die Erfindung betrifft ein Abgasreinigungselement wie etwa einen Abgaskatalysator oder einen Partikelfilter und insbesondere die Anordnung des entsprechenden Elementkörpers, beispielsweise eines Keramikkörpers oder Monolithen, in einem Gehäuse nach dem Oberbegriff des Anspruchs 1.The invention relates to an exhaust gas purification element, such as an exhaust gas catalytic converter or a particle filter, and more particularly to the arrangement of the corresponding element body, for example a ceramic body or monolith, in a housing according to the preamble of
Aus der DE 3432 283 ist ein Abgaskatalysator mit einem in einem metallischen Außengehäuse mit stirnseitigen, insbesondere konischen Abgaszu- und -abführstutzen angeordneten porösen Keramikkörper bekannt. Dieser Keramikkörper ist wabenartig strukturiert und weist eine katalytisch wirksame Oberflächenbeschichtung auf. Zwischen dem Außengehäuse und dem Keramikkörper ist ein thermisch isolierendes, vorzugsweise aus einer so genannten Blähmatte bestehendes Federkissen angeordnet. Derartige Keramikkörper werden als Monolithen bezeichnet.From DE 3432 283 an exhaust gas catalyst with a in a metallic outer housing with frontal, especially conical Abgaszu- and -abführstutzen arranged porous ceramic body is known. This ceramic body is honeycomb-structured and has a catalytically active surface coating. Between the outer housing and the ceramic body, a thermally insulating, preferably consisting of a so-called Blähmatte spring pillow is arranged. Such ceramic bodies are referred to as monoliths.
Nachteilig an dem genannten Stand der Technik ist, dass die aus Silicaten, z.B. Aluminiumsilicaten, einem Blähglimmer, beispielsweise Vermiculit, und einem organischen Bindemittel zusammengesetzte Blähmatte nur bis ca. 750°C geeignet ist den Katalysatorkörper in dem Gehäuse zu lagern. Auch wenn sie durch ihre Ausdehnung bei Hitze in der Lage ist, die Spaltaufweitung zwischen Keramik und Blech zu kompensieren, ist die Verwendung einer solchen Matte nicht bei Dieselpartikelfiltern möglich, die erheblich heißer werden.A disadvantage of the cited prior art is that the silicates, e.g. Aluminum silicates, an expanding mica, such as vermiculite, and an organic binder composite Blähmatte only up to about 750 ° C is suitable to store the catalyst body in the housing. Even though its thermal expansion allows it to compensate for gap expansion between ceramic and sheet metal, the use of such a mat is not possible with diesel particulate filters, which become significantly hotter.
Aus dem Stand der Technik ist weiter die Verendung einer Lagermatte aus polykristallinen Fasern bekannt. Derartige Fasern sind beispielsweise oxidische Fasern wie Aluminiumoxid. Da sie sich bei Hitze nicht ausdehnen, kann die erforderliche Klemmkraft zum Halten des Keramikkörpers nur durch die Elastizität der Fasermatte erreicht werden. Sie sind gegenüber Blähmatten leichter, druckfester, haben eine geringere Wärmeleitfähigkeit und sind bis ca. 1200 °C temperaturbeständig. Daher werden sie zur Lagerung des Keramikkörpers von Dieselpartikelfiltern eingesetzt. Nachteilig ist jedoch, dass die bei der Erwärmung entstehende Spaltaufweitung zwischen Keramik und Blech durch die Federwirkung der Matte nur bedingt kompensierbar ist.The use of a polycrystalline fiber support mat is also known from the prior art. Such fibers are, for example, oxidic fibers such as alumina. Since they do not expand in the heat, the required clamping force for holding the ceramic body can be achieved only by the elasticity of the fiber mat. They are lighter compared to inflatable mats, pressure-resistant, have a lower thermal conductivity and are temperature resistant up to 1200 ° C. Therefore, they are used for storage of the ceramic body of diesel particulate filters. However, it is disadvantageous that the gap widening between ceramic and sheet formed during the heating is only partially compensated by the spring effect of the mat.
Es ist Aufgabe der vorliegenden Erfindung, ein Abgasreinigungselement wie einen Abgaskatalysator oder Partikelfilter mit einer hoch temperaturbeständigen Lagerung des Monolithen zu schaffen, bei dem auch bei hohen Temperaturen die sichere Lagerung des Monolithen in dem Gehäuse gewährleistet ist.It is an object of the present invention to provide an exhaust gas purification element such as a catalytic converter or particle filter with a high temperature resistant storage of the monolith, in which the secure storage of the monolith is ensured in the housing even at high temperatures.
Diese Aufgabe wird durch einen Abgasreinigungselement mit den Merkmalen des Anspruchs 1. Die Unteransprüche geben weitere günstige Ausführungsbeispiele und Fortbildungen der Erfindung an.This object is achieved by an exhaust gas purification element with the features of
Erfindungsgemäß ist bei einem Abgasreinigungselement mit einem Gehäuse und einem in das Gehäuse eingesetzten Monolithen, bei dem zur Fixierung des Monolithen eine Matte zwischen Gehäuse und Monolithen angeordnet ist, die Matte als Hybridmatte bestehend aus einer Blähmatte und einer Fasermatte aus oxidischen Fasern ausgelegt.According to the invention, in an exhaust gas purification element having a housing and a monolith inserted into the housing, in which a mat is arranged between housing and monolith for fixing the monolith, the mat is designed as a hybrid mat consisting of a foaming mat and a fiber mat of oxidic fibers.
Die Kombination der zwei Matten vereint vorteilhaft die Eigenschaften beider Materialien. Die Blähmatte sorgt für eine große HalteKraft und dichtet den Monolith zugleich gegenüber dem Gehäuse ab, während die Fasermatte die notwendige Temperaturbeständigkeit aufweist.The combination of the two mats advantageously combines the properties of both materials. The Blähmatte provides a large holding power and seals the monolith at the same time against the housing, while the fiber mat has the necessary temperature resistance.
Vorteilhafterweise liegt die Blähmatte am Gehäuse und die Fasermatte am Monolithen an. Dadurch kommt nur die hitzebeständigere Fasermatte mit dem heißen Monolith in Kontakt und die Blähmatte zur Ausgleichung des Spalts zwischen Gehäuse und Monolithen befindet sich im kühleren Außenbereich. Insbesondere können die Blähmatte und die Fasermatte miteinander verklebt sein.Advantageously, the Blähmatte on the housing and the fiber mat on the monolith. As a result, only the more heat-resistant fiber mat with the hot monolith in contact and the Blähmatte to equalize the gap between the housing and monoliths is located in the cooler outdoor area. In particular, the Blähmatte and the fiber mat can be glued together.
Voteilhafterweise sind die Fasern der Blähmatte und/oder der Fasermatte biologisch abbaubar und die Fasern der Blähmatte sowie der Fasermatte nicht lungengängig, indem sie einen Durchmesser > 3 µm und/oder ein Länge/Durchmesserverhältnis < 3 aufweisen. Dadurch wird die Verarbeitung, wie auch ein späteres Recycling erleichtert, da keine oder nur geringe Gesundheitsgefährdung besteht.Voteilhafterweise the fibers of the Blähmatte and / or the fiber mat are biodegradable and the fibers of the Blähmatte and the fiber mat non-respirable by having a diameter> 3 microns and / or a length / diameter ratio <3. This facilitates the processing, as well as later recycling, since there is little or no health risk.
In einer weiteren bevorzugten Ausführungsform besteht die Hybridmatte aus mehreren aufeinander folgenden Bläh- und Faserschichten.In a further preferred embodiment, the hybrid mat consists of several successive expanding and fibrous layers.
Der Monolith kann ein Keramikträger eines Katalysators oder ein Keramikkörper eines Partikelfilters sein.The monolith may be a ceramic carrier of a catalyst or a ceramic body of a particulate filter.
Die Erfindung wird nachfolgend in einem vorteilhaften Ausführungsbeispiel mithilfe der beigefügten Zeichnungen näher erläutert. In den Zeichnungen zeigt:

- Fig. 2
- a diagram of the holding force as a function of temperature.
Fig. 1 zeigt ein Ausführungsbeispiel eines Abgasreinigungselements 1, beispielsweise eines Rußpartikelfilters im Querschnitt. In einem ovalen Gehäuse 2 ist ein Monolith 3, der hier aus Keramik besteht, angeordnet. Zwischen dem Gehäuse 2 und dem Monolith 3 ist eine Hybridmatte 4 bestehend aus einer Blähmatte 5 und einer Fasermatte 6 aus oxidischen fasern, beispielsweise Aluminiumoxid, derart angeordnet, dass die Blähmatte 4 nach außen am Gehäuse anliegt, während die Fasermatte 6 innen am Monolithen 3 anliegt. Die Blähmatte 5 und die Fasermatte 6 sind mit einem geeigneten temperaturbeständigen Klebstoff miteinander verklebt.Fig. 1 shows an embodiment of an exhaust
Wenn das Abgasreinigungselement sich im Betrieb erhitzt, so wird die Blähmatte 5 durch die Fasermatte 6 der Hybridmatte 5 vor zu großer Hitze geschützt. Durch die größere Ausdehnung der Blähmatte 5 wird der zwischen Gehäuse 2 und keramischem Monolith 3 entstehende Spalt kompensiert und auch bei hohen Temperaturen eine ausreichend große Haltekraft auf den Monolithen 3 ausgeübt.When the exhaust gas purifying element heats up during operation, the Blähmatte 5 is protected by the
Die Kombination der Blähmatte 5 und der Fasermatte 6 in einer Hybridmatte 4 vereint somit die Vorteile beider unter Vermeidung der Nachteile. Daher ist eine Verwendung bei Dieselpartikelfiltern möglich, die erheblich heißer als etwa bisherige Katalysatoren werden.The combination of the Blähmatte 5 and the
Fig. 2 zeigt in einem Diagramm die Haltekraft bei dem vorliegenden Ausführungsbeispiel als Funktion der Temperatur. Als Hochwert ist schematisch die Haltekraft H bzw. der Mattendruck und als Rechtswert die Temperatur T aufgetragen. Die Linie I zeigt den Verlauf der Haltekraft bei Verwendung von nur einer Blähmatte nach dem Stand der Technik. Die Kurve II zeigt den Verlauf der Haltekraft bei Verwendung von nur einer Fasermatte nach dem Stand der Technik. Rechts von der senkrechten Linie, als Bereich DPF-R bezeichnet, befindet sich der Temperaturbereich, in dem die Regeneration eines Dieselpartikelfilters abläuft. Es ist gut zu sehen, dass die Haltekraft der Blähmatte allein hier stark abfällt und die der Fasermatte allgemein niedriger liegt.Fig. 2 is a diagram showing the holding force in the present embodiment as a function of temperature. As a high value is schematically the holding force H or the matte pressure and applied as the right value, the temperature T. Line I shows the course of the holding force when using only one Blähmatte according to the prior art. The curve II shows the course of the holding force when using only one fiber mat after the state of the art. To the right of the vertical line, designated DPF-R, is the temperature range in which regeneration of a diesel particulate filter occurs. It is good to see that the holding power of the Blähmatte alone here drops sharply and the fiber mat is generally lower.
Die Linie III zeigt die Haltekraft des erfindungsgemäßen Ausführungsbeispiels mit einer Hybridmatte 4 bestehend aus der Kombination aus Blähmatte 5 und Fasermatte 6. Die Haltekraft ist bei hohen Temperaturen signifikant höher und auch der Monolith 3 eines Partikelfilters wird somit insbesondere im Temperaturbereich DPF-R einer Regeneration eines Partikelfilters sicher gehalten.Line III shows the holding force of the embodiment according to the invention with a hybrid mat 4 consisting of the combination of Blähmatte 5 and
