BESCHREIBUNGDESCRIPTION
Filterkörper für eine Abgasreinigungsanlage gemäß Anspruch 1,2,3,4,7. Ein Ausführungsbeispiel ist dargestellt in Fig. 1,2,3.Filter body for an exhaust gas purification system according to claim 1,2,3,4,7. An embodiment is shown in Fig. 1,2,3.
Der Filterkörper (1) aus porösem Material z.B. Keramik besteht aus ersten (4) und zweiten (7) Kanälen, die parallel angeordnet sind. Erster Kanal (4) ist an der ersten Stirnfläche (2) offen und an der zweiten Stirnfläche (3) geschlossen. Zweiter Kanal (7) ist an der ersten Stirnfläche (2) geschlossen und an der zweiten Stirnfläche (3) geschlossen. Im ersten Kanal (4) sind am Hantel iiii des Fi1terkörpers (1) Äuslaßöffnungen angebracht. Das ungereinigte Abgas (A) tritt durch die Einlaßöffnung (5) des ersten Kanals (4) ein und kann durch die Auslaßöffnung (8) des zweiten Kanals (7) als gereinigtes Abgas (R) austreten, nachdem es die poröse Wandung (9) passiert und die Schadstoffpart ike I z.B. Ruß im ersten Kanal (4) zurück geblieben sind. Die Beseitigung der Schadstoffe/partikel in den Kanälen z.b. durch Nachverbrennung ist sehr aufwendig,. daher werden die Schadstoffe zur weiteren Entsorgung durch öffnungen (6) im Hantel (11) abgeführt, und ein Verstopfen der Kanäle von vornherein verhindert. Dichtflächen (12) am Hantel (11) des Filterkörpers trennen und dichten den Schadstoffaustritt vom ungereinigten Abgaseintritt und dem gereinigten Abgasaustritt ab. Zur Erhöhung der Festigkeit sind in den Kanälen Stege (10) angebracht. Ein Mittelsteg im ersten Kanal (4), beliebig viele im zweiten Kanal (7)The filter body (1) made of porous material, e.g. ceramic, consists of first (4) and second (7) channels, which are arranged parallel. The first channel (4) is open at the first end face (2) and closed at the second end face (3). The second channel (7) is closed at the first end face (2) and closed at the second end face (3). In the first channel (4), outlet openings are provided on the handle of the filter body (1). The uncleaned exhaust gas (A) enters through the inlet opening (5) of the first channel (4) and can exit through the outlet opening (8) of the second channel (7) as cleaned exhaust gas (R) after it has passed through the porous wall (9) and the pollutant particles (e.g. soot) have remained in the first channel (4). The removal of the pollutants/particles in the channels, e.g. by post-combustion is very complex. Therefore, the pollutants are discharged for further disposal through openings (6) in the dumbbell (11), and clogging of the channels is prevented from the outset. Sealing surfaces (12) on the dumbbell (11) of the filter body separate and seal the pollutant outlet from the uncleaned exhaust gas inlet and the cleaned exhaust gas outlet. To increase strength, webs (10) are installed in the channels. One central web in the first channel (4), any number in the second channel (7)

The first channel (4) is open at the first (2) and second (3) end faces. The second channel (7) is closed at the first (2) and second (3) end faces. Outlet openings (8) are provided in the second channel (7) in the handle 1 (11) of the filter body (1). The uncleaned exhaust gas (A) enters through the inlet opening (5) of the first channel (4) and exits as cleaned exhaust gas (E) through the outlet opening (8) of the second channel (7) after it has passed through the porous wall (9) and the pollutant particles, e.g. soot, have remained in the first channel (4). To prevent the first channel from becoming blocked, the pollutants are discharged through the outlet opening (6) of the first channel (4) for further disposal. Sealing surfaces (12) on the dumbbell (11) of the filter body (1) separate the outlet of the cleaned exhaust gas (R) from the exhaust gas inlet (A) and the pollutant outlet (S).

Die Erfindung betrifft einen Filterkörper für Abgasreinigungsanlagen z. B. an einem Verbrennungsmotor in einem Kraftfahrzeug.The invention relates to a filter body for exhaust gas purification systems, e.g. on an internal combustion engine in a motor vehicle.
Es sind Filterkörper bekannt, die die Schadstoffe in Abgasen durch Anlagern an das zwischen Abgaseinlaß und Abgasauslaß Angebrachten durchlässigen Material zurückhalten.Filter bodies are known that retain the pollutants in exhaust gases by attaching themselves to the permeable material installed between the exhaust gas inlet and exhaust gas outlet.
Es sind ebenso Filterkörper bekannt, die wabenförmig angeordnete Kanäle besitzen, die einseitig abwechselnd auf den gegenüberliegenden Stirnseiten verschlossen sind, und die Schadstoffe beim Durchgang des Abgases durch die poröse Wandung zurückgehalten werden.Filter bodies are also known which have honeycomb-shaped channels which are alternately closed on opposite sides and which retain the pollutants as the exhaust gas passes through the porous wall.
Bei den genannten Ausführungen werden die Kanäle und Zwischen- Hohlräume bei ungünstigen Betriebszuständen durch die Schadstoffpartikel z.B. Kuß in kurzer Zeit verstopft und damit funktionsuntauglich.In the above-mentioned designs, the channels and intermediate cavities are blocked by pollutant particles (e.g. Kuß) within a short time under unfavourable operating conditions and are therefore no longer able to function.
Es ist daher bekannt, daß die Schadstoffe in einer seperaten Vorrichtung beseitigt werden müssen.It is therefore known that the pollutants must be eliminated in a separate device.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Filterkörper der eingangs genannten Art anzugeben, der in der Weise ausgebildet ist, daß der/die Schadstoff/e oder schadstoffhaltiges Abgas zur weiteren Behandlung aus der Abgasleitung herausgeführt werden kann.The invention is therefore based on the object of specifying a filter body of the type mentioned at the outset, which is designed in such a way that the pollutant(s) or pollutant-containing exhaust gas can be led out of the exhaust line for further treatment.
Diese Aufgabe wird erfindungsgemus dadurch gelöst, daß der Filterkörper Bit wechselweise verschlossenen Kanälen ausgebildet ist, und die Abgaseinlaß- und Auslaßöffnung sowie die Schadstofföffnung räumlich getrennt angebracht sind.This object is achieved according to the invention in that the filter body is designed with alternately closed channels, and the exhaust gas inlet and outlet opening as well as the pollutant opening are arranged spatially separately.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention result from the subclaims.
