Abstract

The IC engine exhaust gas soot filter is esp. for use with air compressors. It is based on a design comprising a casing with inlet and outlet pipe stubs, contg. a mineral filter material coated steadying-tube which the gas enters through radial openings and leaves axially. Several such tubes are used and each tube has a filter-material coating. The tubes are fitted between sheet-metal end pieces (6) one of which embodies outlet openings. The assembly is inserted into the casing as a renewable cartridge.

Description

Rußfilter im Abgasstrom einerSoot filter in the exhaust stream of a

Brennkraftmaschine" Die Erfindung bezieht sich auf einen Rußfilter im Abgasstrom einer Brennkraftmaschine, insbesondere einer luftverdichtenden Brennkraftmaschine, der ein Gehäuse mit Zu- und Ableitungsstutzen für den Abgasstrom und in diesem angeordnetes mineralisches Filtermaterial aufweist, das auf einem mit Durchgangsöffnungen versehenen Stützrohr angeordnet ist, in das der Abgasstrom in radialer Richtung eintritt und das er in axialer Richtung verläßt. Internal combustion engine "The invention relates to a soot filter in the exhaust gas flow of an internal combustion engine, in particular an air-compressing internal combustion engine, the one housing with inlet and outlet stubs for the exhaust gas flow and arranged in this Has mineral filter material, which is provided on a through openings Support tube is arranged into which the exhaust gas flow enters in the radial direction and which he leaves in the axial direction.

Bei einem Rußfilter dieser Art, bekannt aus der DE-OS 2 750 960, ist ein einzelnes Stützrohr vorgesehen, das fest im Gehäuse angeordnet ist. Dadurch sind der Gesamtoberfläche des auf dem Stützrohr angeordneten Filtermateriales verhältnismäßig enge Grenzen gesetzt, und es kann bei ungünstigen Betriebsbedingungen der Brennkraftmaschine zu einem Rußbefall kommen, der nicht mehr in allen Teilen von selbst abbrennt, so daß sich der Rußfilter mit der Zeit zusetzt und insgesamt ausgetauscht werden muß.In a soot filter of this type, known from DE-OS 2 750 960, is a single support tube is provided which is fixedly arranged in the housing. Through this are in proportion to the total surface area of the filter material arranged on the support tube set narrow limits, and it can under unfavorable operating conditions of the internal combustion engine soot that no longer burns off by itself in all parts, so that the soot filter clogs over time and has to be replaced as a whole.

Weil dadurch die Lebensdauer des Rußfilters vermindert wird und ein Gesamtaustausch des Rußfilters umständlich und teuer ist, macht es sich die Erfindung zur Aufgabe, einen Rußfilter mit möglichst großer Filtermaterialoberfläche und derart auszubilden, daß im Falle eines erforderlich werdenden Austausches das Filtergehäuse selbst nicht ausgetauscht zu werden braucht.Because this reduces the life of the soot filter and a Complete replacement of the soot filter is cumbersome and expensive is, makes It is the object of the invention to provide a soot filter with the largest possible filter material surface and to be designed in such a way that, in the event that an exchange becomes necessary, the The filter housing itself does not need to be replaced.

Erfindungsgemäß wird die gestellte Aufgabe dadurch gelöst, daß mehrere mit Filtermaterial belegte Stützrohre als Einbaueinheit zu einer auswechselbaren Kartusche zusammengefaßt sind.According to the invention the object is achieved in that several Support tubes covered with filter material as a built-in unit for an exchangeable one Cartridge are summarized.

Durch die Anordnung mehrerer Stützrohre wird die Gesamtoberfläche des Filtermateriales wesentlich vergrößer- Der Rußbefall ist pro Flächeneinheit kleiner, so daß ein selbsttätiges Abbrennen unter günstigeren Ausgangsbedingungen vor sich gehen kann. Sollte trotzdem der Fall eintreten, daß eine Verstopfung des Rußfilters eintritt, braucht nicht der gesamte Rußfilter ausgewechselt zu werden, sondern nur die zu einer Kartusche zusammengefaßten Stützrohre mit dem Filtermaterial.By arranging several support tubes, the total surface is The soot infestation is per unit area smaller, so that automatic burning off under more favorable starting conditions can go on. Should it nevertheless occur that a blockage of the Soot filter occurs, the entire soot filter does not need to be replaced, but only the support tubes with the filter material, which are combined to form a cartridge.

In der Zeichnung ist der Gegenstand der Erfindung schematisch in einem Ausführungsbeispiel in einem Querschnitt durch einen Rußfilter dargestellt.In the drawing, the object of the invention is schematically in one Embodiment shown in a cross section through a soot filter.

In einem zylindrischen Gehäuse l mit einem radialen Zuleitungsstutzen 2 ist auf mehreren mit Abstand parallel zueinander angeordneten Stützrohren 3, die Durchgangsöffnungen 4 aufweisen, mineralisches Filtermaterial 5 angeordnet. Die Stützrohre 3 sind jeweils an beiden Enden an Blechwandungen 6 befestigt und mit diesen Blechwandungen als Einbaueinheit als Kartusche auswechselbar im Gehäuse l gelagert. Die Blechwandung an einer Endseite der Stützrohre ist geschlossen, während die Blechwandung an der anderen Endseite der Stützrohre 3 Öffnungen aufweist, damit das durch das Filtermaterial 5 in die Stützrohre 3 eingedrungene Abgas aus den Stützrohren in axialer Richtung abströmen kann.In a cylindrical housing l with a radial feed pipe 2 is on a plurality of spaced parallel support tubes 3, which Have passage openings 4, mineral filter material 5 arranged. the Support tubes 3 are attached at both ends to sheet metal walls 6 and with these sheet metal walls as a built-in unit as a cartridge replaceable in the housing l stored. The sheet metal wall on one end side of the support tubes is closed while the sheet metal wall has 3 openings on the other end side of the support tubes so that the exhaust gas that has penetrated through the filter material 5 into the support tubes 3 from the support tubes can flow off in the axial direction.
