The invention relates to an exhaust gas particulate filter element, comprising a filter body that is placed inside a housing. Said filter body has individual filter plates made of sintered metal, which are arranged next to one another in an essentially parallel manner and which have intermediate spaces that are located between the filter plates. The housing is provided with a supply line for exhaust gas and with a withdrawal line for purified gas. The flowing against of the filter body by the exhaust gas into the intermediate spaces between the filter plates ensues from an area located outside of the filter body and into an area located inside the filter body. According to the invention, the filter body (4), with regard to its position, can be variably accommodated inside the housing (2) in such a manner that the withdrawal line (10) can be placed on the housing (2) in any position relative to the supply line (3). This exhaust gas particulate filter element is for use in exhaust systems, particularly those of goods-carrying vehicles.

Description

Abgas-Partikelfilterelement Exhaust particulate filter element

Die Erfindung betrifft ein Abgas-Partikelfilterelement mit einem in einem Gehäuse angeordneten Filterkörper nach der im Oberbegriff von Anspruch 1 näher definierten Art.The invention relates to an exhaust gas particle filter element with a filter body arranged in a housing according to the kind defined in the preamble of claim 1.

Gattungsgemäße Abgas-Partikelfilterelemente sind aus der DE 199 10 258 AI und der DE 199 10 259 AI bekannt. Dabei wird über eine Zuführleitung Abgas zu dem Filterkörper geleitet, durch den Filterkörper gefiltert und über eine Abführleitung aus dem Gehäuse geleitet, wobei der Filterkörper geradlinig durchströmt wird. Diese Art der Durchströmung stellt in verschiedenen Abgasanlagen, in denen diese Abgas-Partikelfilterelemente eingebaut werden sollen, jedoch ein Hindernis dar, da nur eine sehr starre Anbringung des Abgas-Partikelfilter- elements an der Abgasanlage möglich ist.Generic exhaust gas particle filter elements are known from DE 199 10 258 AI and DE 199 10 259 AI. Exhaust gas is conducted to the filter body via a supply line, filtered through the filter body and passed out of the housing via a discharge line, with the filter body flowing through in a straight line. However, this type of flow represents an obstacle in various exhaust systems in which these exhaust gas particle filter elements are to be installed, since only a very rigid attachment of the exhaust gas particle filter element to the exhaust system is possible.

Ein weiteres gattungsgemäßes Abgas-Partikelfilterelement ist aus der DE 100 42 542 AI bekannt. Dabei sind die Zuführleitung und die Abführleitung, die wiederum Teile einer Abgasanlage darstellen, so angeordnet, dass das gereinigte Gas das Abgas-Partikelfilterelement auf der Seite der Einleitung des Abgases verlässt . Zu der hierfür notwendigen Umleitung des Gases sind jedoch innerhalb des Gehäuses verhältnismäßig aufwendige Maßnahmen erforderlich.Another generic exhaust gas particle filter element is known from DE 100 42 542 AI. The supply line and the discharge line, which in turn represent parts of an exhaust system, are arranged such that the cleaned gas leaves the exhaust gas particle filter element on the side of the introduction of the exhaust gas. For the necessary diversion of the gas, however, relatively complex measures are required within the housing.

Bei aus dem allgemeinen Stand der Technik bekannten Abgas- Partikelfilterele enten, die Filterkörper aus keramischen Materialien aufweisen, ist eine Durchströmung des Filterkörpers nur in linearer Richtung möglich. Es ist Aufgabe der vorliegenden Erfindung, ein Abgas-Partikelfilterelement zu schaffen, welches an die verschiedensten Gegebenheiten in Abgasanlagen angepasst werden kann.In exhaust gas particle filters known from the general prior art, which have filter bodies made of ceramic materials, flow through the filter body is only possible in a linear direction. It is an object of the present invention to provide an exhaust gas particle filter element which can be adapted to the most varied of conditions in exhaust gas systems.

Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst .According to the invention, this object is achieved by the features mentioned in claim 1.

Erfindungsgemäß ist der Filterkörper bezüglich seiner Lage derart variabel innerhalb des Gehäuses unterbringbar, dass die Abführleitung in einer beliebigen Lage relativ zu der Zuführleitung an dem Gehäuse angebracht werden kann. Durch diese frei wählbare Positionierung der Abführleitung relativ zu der Zuführleitung lässt sich das erfindungsgemäße Abgas- Partikelfilterelement ohne die Notwendigkeit einschneidender und somit sehr aufwendiger Änderungen an die unterschiedlichsten Abgasanlagen anpassen. Ein weiterer Vorteil der erfindungsgemäßen Lösung ist, dass auf Änderungen des Gehäuses, in dem sich der Filterkörper befindet, vollständig verzichtet werden kann.According to the invention, the position of the filter body can be accommodated within the housing in such a variable manner that the discharge line can be attached to the housing in any position relative to the supply line. This freely selectable positioning of the discharge line relative to the supply line means that the exhaust gas particle filter element according to the invention can be adapted to a wide variety of exhaust gas systems without the need for drastic and therefore very complex changes. Another advantage of the solution according to the invention is that changes to the housing in which the filter body is located can be completely dispensed with.

In einer Weiterbildung der Erfindung ist vorgesehen, dass in dem Bereich innerhalb des Filterkörpers ein mit Öffnungen in Richtung der Filterplatten versehenes Sammelrohr angeordnet ist, welches mit der Abführleitung verbunden ist. Durch dieses Sammelrohr wird eine gezielte Abführung des Gases aus dem Filterkörper in die Abführleitung erreicht. Hierbei kann das Sammelrohr in einer beliebigen Lage innerhalb des Filterkorpers angeordnet sein, sodass die oben beschriebene, beliebige Orientierung der Abführleitung an dem Gehäuse erreicht wird.In a further development of the invention it is provided that in the area inside the filter body a collecting tube is provided which is provided with openings in the direction of the filter plates and which is connected to the discharge line. Through this collecting tube, a targeted discharge of the gas from the filter body into the discharge line is achieved. Here, the collecting pipe can be arranged in any position within the filter body, so that the above-described, arbitrary orientation of the discharge line on the housing is achieved.

Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den restlichen Unteransprüchen sowie aus den nachfolgend anhand der Zeichnung prinzipmäßig dargestellten Ausführungsbeispielen. Dabei zeigen:Further advantageous refinements and developments of the invention result from the remaining subclaims and from the exemplary embodiments illustrated in principle below with reference to the drawing. Show:

Fig. 2 eine zweite Ausführungsform des erfindungsgemäßen Abgas-Partikelfilterelements ; und2 shows a second embodiment of the exhaust gas particle filter element according to the invention; and

Fig. 3 eine dritte Au führungsform des erfindungsgemäßen Abgas-Partikelfilterelements .Fig. 3 shows a third embodiment of the exhaust gas particulate filter element according to the invention.

Fig. 1 zeigt in einer schematischen Seitenansicht ein Abgas- Partikelfilterelement 1, welches dafür vorgesehen ist, die Abgase einer nicht dargestellten Dieselbrennkraftmaschine zu reinigen. Das Abgas-Partikelfilterelement 1 wird insbesondere bei Abgasanlagen von Nutzfahrzeugen eingesetzt und weist ein Gehäuse 2 auf, zu welchem eine Zuführleitung 3 für Abgas führt. Durch die Zuführleitung 3, welche einen Teil einer in ihrer Gesamtheit nicht dargestellten Abgasanlage bildet, wird das Abgas in das Innere des Gehäuses 2 geleitet und strömt dort zu einem Filterkörper 4, welcher einzelne, im wesentlichen parallel nebeneinander angeordnete Filterplatten 5 aus Sintermetall aufweist, zwischen denen sich jeweils Zwischenräume 6 befinden.Fig. 1 shows a schematic side view of an exhaust gas particle filter element 1, which is intended to clean the exhaust gases of a diesel engine, not shown. The exhaust gas particle filter element 1 is used in particular in exhaust systems of commercial vehicles and has a housing 2 to which a supply line 3 for exhaust gas leads. Through the supply line 3, which forms part of an exhaust system, not shown in its entirety, the exhaust gas is directed into the interior of the housing 2 and flows there to a filter body 4, which has individual filter plates 5 made of sintered metal, which are arranged essentially parallel to one another which each have gaps 6.

Der Filterkörper 4 entsteht durch Verschweißen der Filterplatten 5, wobei sich zwischen den Filterplatten 5 die jeweiligen Zwischenräume 6 befinden. In diesem Zusammenhang lassen sich durch eine unterschiedliche Anzahl an Filterplatten 5 Filterkörper 4 mit unterschiedlicher Größe herstellen.The filter body 4 is formed by welding the filter plates 5, the respective gaps 6 being located between the filter plates 5. In this context, filter bodies 4 of different sizes can be produced by a different number of filter plates 5.

Die Anströmung des Filterkörpers 4 durch das Abgas erfolgt in die Zwischenräume 6 zwischen den Filterplatten 5 von einem außerhalb des Filterkörpers 4 liegenden Bereich 7. Das Abgas strömt in die Zwischenräume 6 und somit in den Filterkörper 4 ein und gelangt auf diese Weise zu einem Bereich 8 innerhalb des Filterkorpers 4. In diesem Bereich 8 innerhalb des Fil- terkörpers 4 befindet sich ein Sammelrohr 9, welches an seinem Außenumfang mit nicht dargestellten Öffnungen in Richtung der Filterplatten 5 versehen ist, sodass das durch die Zwischenräume 6 strömende Abgas in das Sammelrohr 9 gelangen kann. Prinzipiell muss sich das Sammelrohr 9 nicht in der Mitte der Filterplatten 5 befinden, sondern kann an jeder beliebigen Stelle innerhalb des Filterkörpers 4 angeordnet sein.The flow of the filter body 4 through the exhaust gas takes place in the spaces 6 between the filter plates 5 from an area 7 located outside the filter body 4. The exhaust gas flows into the spaces 6 and thus into the filter body 4 and in this way reaches an area 8 inside the filter body 4. In this area 8 within the filter terkörpers 4 is a manifold 9, which is provided on its outer circumference with openings, not shown, in the direction of the filter plates 5, so that the exhaust gas flowing through the spaces 6 can get into the manifold 9. In principle, the collecting tube 9 does not have to be located in the middle of the filter plates 5, but can be arranged at any point within the filter body 4.

Das Sammelrohr 9 ist mit einer Abführleitung 10 verbunden, welche dazu dient, das gereinigte Gas aus dem Gehäuse 2 abzuführen und in die Abgasanlage zurückzuleiten. Die Abführleitung 10 bildet somit ebenfalls einen Teil der Abgasanlage und wird im vorliegenden Fall mittels eines Halteelements 11 an dem Gehäuse 2 befestigt. Das Halteelement 11 dient auch zur Anbringung des Filterkörpers 4 an dem Gehäuse 2. Auf der dem Halteelement 11 gegenüberliegenden Seite des Filterkörpers 4 ist ein weiteres Halteelement 12 vorgesehen, welches allerdings lediglich mit dem Filterkörper 4 und nicht mit der Abführleitung 10 verbunden ist. Selbstverständlich weisen die Halteelemente 11 und 12 geeignete, nicht dargestellte Öffnungen zum Durchlassen des Abgases zu dem Filterkörper 4 auf. Die Abführleitung 10 weist bei der Ausführungsform gemäß Fig. 1 eine 90° -Biegung auf und verlässt das Gehäuse 2 auf derselben Seite, an der die Zuführleitung 3 angeordnet ist. Die Anströmung des Filterkörpers 4 erfolgt also radial, die Abströ- mung axial .The collecting pipe 9 is connected to a discharge line 10, which serves to discharge the cleaned gas from the housing 2 and to return it to the exhaust system. The discharge line 10 thus also forms part of the exhaust system and in the present case is fastened to the housing 2 by means of a holding element 11. The holding element 11 also serves to attach the filter body 4 to the housing 2. On the side of the filter body 4 opposite the holding element 11, a further holding element 12 is provided, which, however, is only connected to the filter body 4 and not to the discharge line 10. Of course, the holding elements 11 and 12 have suitable openings, not shown, for the passage of the exhaust gas to the filter body 4. In the embodiment according to FIG. 1, the discharge line 10 has a 90 ° bend and leaves the housing 2 on the same side on which the supply line 3 is arranged. The flow against the filter body 4 is radial, the flow axially.

Fig. 2 zeigt eine weitere Ausführungsform des Abgas-Partikel- filterelements 1 in einer Draufsicht. Wie aus einem Vergleich von Fig. 1 mit Fig. 2 erkennbar ist, ist der Filterkörper 4 derart variabel in dem Gehäuse 2 untergebracht, dass die Abführleitung 10 in einer beliebigen Lage relativ zu der Zuführleitung 3 an dem Gehäuse 2 angebracht werden kann. In Fig. 2 ist nämlich die Abführleitung 10 in einer gegenüber der Zuführleitung 3 verdrehten Lage angeordnet, wobei es sich in diesem Fall um eine um 90° verdrehte Lage handelt. Bei entsprechenden Einbausituationen sind jedoch auch andere Winkellagen möglich.2 shows a further embodiment of the exhaust gas particle filter element 1 in a plan view. As can be seen from a comparison of FIG. 1 with FIG. 2, the filter body 4 is accommodated in the housing 2 in such a variable manner that the discharge line 10 can be attached to the housing 2 in any position relative to the feed line 3. 2, the discharge line 10 is namely arranged in a position rotated relative to the supply line 3, in which case it is a position rotated by 90 °. at corresponding installation situations, however, other angular positions are also possible.

Zwar ist der Filterkörper 4 wie oben beschrieben an dem Gehäuse 2 befestigt, diese Befestigung mittels der Halteelemente 11 und 12 kann jedoch verändert werden, sodass sich eine flexible Anordnung der Abführleitung 10 gegenüber der Zuführleitung 3 ohne die Notwendigkeit einer grundlegenden Änderung des Gehäuses 2 ergibt .Although the filter body 4 is fastened to the housing 2 as described above, this fastening by means of the holding elements 11 and 12 can be changed, so that there is a flexible arrangement of the discharge line 10 relative to the feed line 3 without the need for a fundamental change in the housing 2.

Bei der Ausführungsform des Abgas-Partikelfilterelements 1 gemäß Fig. 3 ist die Abführleitung 10 auf der der Zuführleitung 3 gegenüberliegenden Seite des Gehäuses 2 angeordnet. Hierbei sind innerhalb des Gehäuses 2 mehrere Katalysatorelemente 13 mit zugeordneten Schalldämpferelementen 14 angeordnet . Die Anströmung des Filterkörpers 4 erfolgt dabei wiederum von dem sich außerhalb des Filterkörpers 4 befindlichen Bereich 7 in den inneren Bereich 8 des Filterkörpers 4.In the embodiment of the exhaust gas particulate filter element 1 according to FIG. 3, the discharge line 10 is arranged on the side of the housing 2 opposite the supply line 3. Here, a plurality of catalytic converter elements 13 with associated muffler elements 14 are arranged within the housing 2. The flow against the filter body 4 in turn takes place from the area 7 located outside the filter body 4 into the inner area 8 of the filter body 4.

Die Lage der Filterplatten 5 spielt für die Funktion des Abgas-Partikelfilterelements 1 im Prinzip keine Rolle. Dies gilt auch für die Anströmung des Filterkörpers 4, wobei es lediglich erforderlich ist, dass die Zwischenräume 6 angeströmt werden. In principle, the position of the filter plates 5 is of no importance for the function of the exhaust gas particle filter element 1. This also applies to the flow against the filter body 4, it only being necessary for the gaps 6 to be flowed against.
