Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines zur Abgasreinigung dienenden Katalysatorwabenkörpers durch Bildung eines spiraligen Wabenkörpers aus abwechselnd übereinander angeordnetem gewellten und planen Folienband.The invention relates to a method for producing a catalyst honeycomb body used for exhaust gas purification Formation of a spiral honeycomb alternating stacked corrugated and flat film tape.

Bei einem bekannten Verfahren dieser Art (GB-A-20 69 364) wird der Wabenkörper zunächst aus unbeschichteten Folien­ bändern gewickelt, worauf an einer Stirnseite Schweißnähte gelegt werden, welche die Wicklung fixieren. Erst danach werden die bereits zum Wabenkörper vereinigten Folienbän­ der mit Stützmaterial und katalytisch aktivem Material beschichtet. Dabei können sich jedoch diese Materialien häufig nicht gleichmäßig auf den Folienbändern und damit im Wabenkörper verteilen.In a known method of this type (GB-A-20 69 364) the honeycomb body is initially made of uncoated films tapes, with welds on one end which fix the winding. Only after become the foil strips already combined to form the honeycomb body which is coated with support material and catalytically active material. However, these materials often cannot evenly on the foil strips and thus in the honeycomb body to distribute.

Es ist Aufgabe der Erfindung, ein gattungsgemäßes Verfah­ ren so zu verbessern, daß einerseits die Folienbänder gleichmäßig beschichtet und der Wabenkörper dennoch in sich zu einer stabilen Einheit fixiert ist.It is an object of the invention, a generic method Ren to improve so that the one hand the film tapes evenly coated and the honeycomb body still in is fixed in a stable unit.

Die Aufgabe wird bei einem gattungsgemäßen Verfahren da­ durch gelöst, daß das im voraus sowohl mit Stützmaterial als auch mit katalytisch aktivem Material beschichtete gewellte und plane Folienband einen Wabenkörper ohne Zen­ tralachse oder -blech bildet, und daß das Auflösen des Wabenkörpers und ein Aneinanderreiben der Folienbänder durch wenigstens eine durch den Wabenkörper hindurchge­ führte Stütze verhindert werden, wobei die Länge dieser Stütze 1 bis 10 mm größer als der Durchmesser des Waben­ körpers ist. The task is there in a generic method solved by that in advance with both support material as well as corrugated coated with catalytically active material and plan foil tape a honeycomb body without Zen tralachse or sheet forms, and that the dissolution of the Honeycomb body and rubbing the film strips together  through at least one through the honeycomb body led prop can be prevented, the length of this Support 1 to 10 mm larger than the diameter of the honeycomb body is.  

Man kann dies so ausführen, daß man im voraus mit einer Stützmaterial- und einer Schicht aus katalytisch aktivem Material beschichtetes planes und gewelltes Folienband so um eine Achse bestimmter Größe wickelt, daß nach dem Herausnehmen der Achse in Wabenkörpermitte ein länglicher Hohlraum gewünschter Größe verbleibt. Danach wird der Wabenkörper in ovale Form gestaucht, d. h. er hat dann im Querschnitt sog. oder "Fahr­ bahn"-Form, und der in seinem Zentrum vorhanden gewesene Hohlraum ist beseitigt. Danach wird durch den Wabenkörper eine Stütze gepreßt oder geschossen, die verhindert, daß sich der Wabenkör­ per auflöst und die Folienbänder aneinander reiben. So entsteht ein formbeständiger, starrer Körper.You can do this in such a way that ahead with a support material and a layer of flat and corrugated foil tape coated with catalytically active material around an axis certain size wraps that after removing the axle in the middle of the honeycomb body an elongated cavity of the desired size remains. Then the honeycomb body is compressed into an oval shape, d. H. he then has so-called "Fahr." orbital "shape, and the cavity present at its center is eliminated. Then the honeycomb is used to support the body pressed or shot, which prevents the honeycomb body per dissolves and rub the foil strips together. This is how it is created a dimensionally stable, rigid body.

Es besteht die Möglich­ keit, zur Herstellung des Wabenkörpers im voraus beschichtetes planes und gewelltes Folienband unmittelbar so zu einem im Quer­ schnitt runden Körper zu wickeln, daß in seinem Zentrum kein länglicher Hohlraum entsteht. Danach wird durch den Körper eine Stütze gedrückt oder geschossen, die verhindert, daß sich der Wabenkörper auflöst und sich die Folienbänder aneinander rei­ ben. So entsteht ein formbeständiger, starrer Körper. There is a possibility speed, coated in advance for the production of the honeycomb body flat and corrugated foil tape directly to one in the cross cut round body to wrap that in its center no elongated cavity is created. After that, one becomes through the body Support pressed or shot, which prevents the The honeycomb body dissolves and the film strips tear together ben. This creates a dimensionally stable, rigid body.  

Weiterhin können zwei oder mehr Stützen so durch den Wabenkörper gedrückt werden, daß sie entweder nebeneinander oder hintereinander zu liegen kommen.Furthermore two or more supports are pressed through the honeycomb body so that they either come to lie side by side or one behind the other.

Das Durchstoßen der Stützen durch den Wabenkörper kann entweder durch Drücken oder durch Schießen erfolgen. Man kann auch am Wabenkörper im voraus eine der Größe der Stütze entsprechende Öffnung, zum Beispiel durch Bohren, anbringen und anschließend eine diese Öffnung füllende Stütze einführen.Piercing the supports through the honeycomb body can either by pressing or by shooting. One can also on the honeycomb body beforehand an opening corresponding to the size of the support, for example by drilling, attaching and then one insert the support to fill this opening.

Die durch den Wabenkörper zu steckende Stütze hat im Querschnitt vorzugsweise runde, ovale, quadratische oder rechteckige Form. Die Länge der durch den Wabenkörper zu steckenden Stütze ist gleich dem Durchmesser des Körpers (runder Körper) oder gleich der Höhe des Körpers und ist um 1 bis 10 mm größer als der Wabenkörperdurchmesser bzw. die Wabenkörperhöhe.The cross-section of the support to be inserted through the honeycomb body preferably round, oval, square or rectangular shape. The length of the through the honeycomb body The support to be inserted is equal to the diameter of the body (rounder Body) or equal to the height of the body and is 1 to 10 mm larger than the honeycomb body diameter or the honeycomb body height.

Die durch den Wabenkörper gesteckte(n) Stütze(n) besteht/bestehen bevorzugt aus feuerbeständigem Stahl.The support (s) inserted through the honeycomb body exists preferably made of fire-resistant steel.
