Description

Aufgebauter Katalysatorträgerkörper mit großer QuerschnittsflächeAssembled catalyst carrier body with a large cross-sectional area

Die vorliegende Erfindung betrifft einen Katalysatorträgerkörper nach dem Oberbegriff des Anspruchs 1.The present invention relates to a catalyst carrier body according to the preamble of claim 1.

Bei der katalytischen Reinigung von Abgasen und bei anderen katalytischen Prozessen werden für größere Anlagen Katalysatorträgerkörper mit großer Querschnittsfläche für große Durchsätze benötigt. Es ist bekannt, solche Katalysatorträgerkörper aus abwechselnden Lagen von glatten und gewellten Blechen zu wickeln oder zu schichten. Solche gewickelten oder geschichteten Blechpakete werden meist noch einer anschließenden fügetechnischen Behandlung, beispielsweise Löten, unterworfen.In the catalytic purification of exhaust gases and in other catalytic processes, catalyst supports with large cross-sectional areas for large throughputs are required for larger plants. It is known to wind or layer such catalyst carrier bodies from alternating layers of smooth and corrugated sheets. Such wound or layered laminated cores are usually still subjected to subsequent joining treatment, for example soldering.

Es ist zwar prinzipiell möglich, Katalysatorträgerkörper von fast beliebigem Durchmesser zu wickeln bzw. von beliebig großer Querschnittsfläche zu schichten, jedoch treten praktische Schwierigkeiten bei der Handhabung auf, sobald bestimmte Größen deutlich überschritten werden sollen. So ist ein Beloten von sehr großen Strukturen schwierig und es werden auch sehr große Lötöfen benötigt für die anschließende Wärmebehandlung. Auch ansonsten bietet die Handhabung schon wegen der Dimensionen und des Gewichtes größere Schwierigkeiten, wozu noch Probleme bei der Beschichtung mit katalytischem Material hinzutreten. So tritt ein an sich unerwarteter Effekt auf, nämlich daß größere Einheiten mit einem bestimmten Volumen bei vorgegebenen Kanalquerschnitten der einzelnen Strömungskanäle teurer sein können als mehrere kleinere Katalysatorträgerkörper mit dem gleichen Gesamtvolumen.In principle, it is possible to wind catalyst carrier bodies of almost any diameter or to layer them with any cross-sectional area, but practical difficulties in handling arise as soon as certain sizes are to be significantly exceeded. Soldering of very large structures is difficult and very large soldering furnaces are also required for the subsequent heat treatment. Otherwise, the handling, due to the dimensions and the weight, presents greater difficulties, which also add to problems with the coating with catalytic material. Thus, an unexpected effect occurs, namely that larger units with a certain volume can be more expensive for a given channel cross-section of the individual flow channels than several smaller catalyst carrier bodies with the same total volume.

Aus kleinen Einheiten aufgebaute Katalysatorträgerkörper sind beispielsweise aus der DE-A 2 247 947 bekannt. Auch in der US-A 4 303 618 sind dicht aneinanderliegende, runde Katalysatorkörper gleicher Größe bekannt. Bei den bekannten Anordnungen kann jedoch eine vorgegebene Fläche nur unvollkommen ausgenutzt werden, da zwischen den einzelnen Körpern noch freie Zwischenräume von .erheblicher Größe verbleiben.Catalyst carrier bodies constructed from small units are known, for example, from DE-A 2 247 947. US Pat. No. 4,303,618 also discloses round catalyst bodies of the same size lying close together. In the known arrangements, however, a predetermined area can only be used incompletely, since there are still free spaces of considerable size between the individual bodies.

Aufgabe der vorliegenden Erfindung ist daher ein aus kleineren Einheiten aufgebauter Katalysatorträgerkörper mit großer und/oder unregelmäßig geformter Querschnittsfläche, der die oben genannten Probleme vermeidet.The object of the present invention is therefore a catalyst carrier body composed of smaller units with a large and / or irregularly shaped cross-sectional area, which avoids the problems mentioned above.

Zur Lösung dieser Aufgabe wird gemäß dem Anspruch 1 vorgeschlagen, den Katalysatorträgerkörper aus mehreren unterschiedlichen kleineren Einheiten aufzubauen, die in einer vorgegebenen Querschnittsfläche nebeneinander in möglichst dichter Packung angeordnet sind. Bei dieser Vorgehensweise können auch für Einzelstücke mit großer Querschnittsfläche die Kostenvorteile einer Serienfertigung von kleineren Einheiten ausgenutzt werden. Statt Wickel- und Handhabungsvorrichtungen und dergleichen für spezielle Katalysatorträgerkörpertypen mit großem Querschnitt oder einer unregelmäßigen Querschnittsfläche zu verwenden, können solche Katalysatorträgerkörper in einfacher Weise aus mehreren kleineren Einheiten zusammengestellt werden. Ein solches System ist sehr flexibel und ermöglicht eine rentable Fertigung von kleineren Stückzahlen.To achieve this object, it is proposed according to claim 1 to construct the catalyst carrier body from a plurality of different smaller units which are arranged next to one another in a densely packed manner in a predetermined cross-sectional area. With this procedure, the cost advantages of series production of smaller units can also be exploited for single pieces with a large cross-sectional area. Instead of using winding and handling devices and the like for special types of catalyst supports with a large cross-section or with an irregular cross-sectional area, such catalyst supports can be easily assembled from several smaller units. Such a system is very flexible and enables profitable production of small quantities.

Wichtig ist, daß ein vorgegebener Querschnitt zunächst mit möglichst großen kreisförmigen Einheiten ausgefüllt und die dann noch vorhandenen Lücken mit kleineren Einheiten weiter geschlossen werden sollen. Durch die Verwendung von nur zwei oder drei verschiedenen Durchmessern bei den kleinen Einheiten läßt sich bereits der weitaus größte Teil der vorhandenen Querschnittsfläche mit Katalysatorträgerkörpern ausfüllen, insbesondere dann, wenn in gewissen Grenzen elastische Einheiten verwendet werden, wie sie z.B. in der EP-A 0 220 468 angegeben sind. Störend bei erfindungsgemäß aufgebauten Katalysatorträgerkörpern können eventuell noch bestehende unausgefüllte Kanäle in der vorgegebenen Querschnittsfläche sein. Sofern diese Kanäle nicht zu groß sind, stellt dies kein Problem dar. Andernfalls können solche Freiräume gegen Gasdurchlaß abgedichtet werden. Gemäß Anspruch 4 erfolgt das Abdichten eventueller Freiräume durch Vergießen mit einer keramischen Masse. Auch eine Verwendung von geeigneten Masken auf der Einlaß- oder Auslaßseite des Katalysatorträgerkörpers ist möglich.It is important that a given cross-section is initially filled with circular units that are as large as possible and that the gaps still present are to be closed further with smaller units. By using only two or three different diameters for the small units, the vast majority of the existing cross-sectional area can already be filled with catalyst carrier bodies, especially if elastic units are used within certain limits, such as those e.g. are specified in EP-A 0 220 468. In the case of catalyst carrier bodies constructed according to the invention, any unfilled channels in the predetermined cross-sectional area can still be present. If these channels are not too large, this is not a problem. Otherwise such free spaces can be sealed against gas passage. According to claim 4, the sealing of any free spaces is carried out by casting with a ceramic mass. It is also possible to use suitable masks on the inlet or outlet side of the catalyst carrier body.

Wie in Anspruch 2 weiterhin ausgeführt, beschränkt sich die Verwendung von kleineren Einheiten natürlich nicht auf kreisförmige Ausführungen. Sofern Einheiten mit anders geformten Querschnitten preisgünstig zur Verfügung stehen, können Einheiten von beliebiger Form verwendet werden, wie sie z.B. in der EP-A 0 210 546 beschrieben werden.As further stated in claim 2, the use of smaller units is of course not limited to circular designs. If units with differently shaped cross sections are available at low cost, units of any shape can be used, e.g. can be described in EP-A 0 210 546.

Zur Stabilisierung der aufgebauten Katalysatorträgerkörper wird im Anspruch 3 vorgeschlagen, die einzelnen Einheiten an ihren Berührungsstellen untereinander fügetechnisch zu verbinden, vorzugsweise zu verlöten. Dies kann gegebenenfalls gleichzeitig mit der Verlötung der Blechlagen in den kleineren Einheiten erfolgen.To stabilize the built-up catalyst carrier body, it is proposed in claim 3 to connect the individual units at their points of contact with one another, preferably to solder them. If necessary, this can be done simultaneously with the soldering of the sheet metal layers in the smaller units.

Eine weitere Möglichkeit zur Stabilisierung des gesamten Aufbaus eines erfindungsgemäßen Katalysatorträgerkörpers besteht darin, die kleineren Einheiten gemäß Anspruch 5 in eine oder mehrere vorgeformte Platten in entsprechende Löcher einzusetzen und fügetechnisch zu befestigen. Solche Platten können auf einfache Weise gestanzt oder anderweitig hergestellt werden und bilden eine stabile Halterung für den aufgebauten Katalysatorträgerkörper.Another possibility for stabilizing the entire structure of a catalyst carrier body according to the invention is to insert the smaller units according to claim 5 into one or more preformed plates in corresponding holes and to fasten them by means of joining technology. Such plates can be stamped or otherwise produced in a simple manner and form a stable holder for the built-up catalyst carrier body.

Die kleineren Einheiten 11 können insbesondere serienmäßig hergestellte, einfache zylindrisch gewickelte Katalysatorträgerkörper sein. Wie gestrichelt angedeutet, werden in den Zwischenräumen 15 zwischen den kleineren Einheiten 11 weitere noch kleinere Einheiten 17 angeordnet. Das gleiche gilt für die Zwischenräume 14 zwischen den kleineren Einheiten 11 und dem Außenmantel 10, wo weitere kleinere Einheiten 16 angeordnet werden können. Die Berührungsstellen 12 zwischen den Einheiten 11 und gegebenenfalls den Einheiten 16, 17 und die Berührungsstellen 13 mit der Berandung können fügetechnisch verbunden werden. Eventuell noch verbleibende Zwischenräume können mit keramischer Masse ausgegossen, oder durch geeignete Lochmasken abgedeckt werden. Auch das Einsetzen der kleineren Einheiten 11, 16, 17 in eine Lochplatte, die genau der in Figur 1 dargestellten Konfiguration entspricht, ist möglich.FIG. 1 shows a cross section through a built-up catalyst carrier body 10, which is composed of several smaller circular units 11. The smaller units 11 can NEN in particular mass-produced, simple cylindrical wound catalyst carrier body. As indicated by dashed lines, 11 even smaller units 17 are arranged in the spaces 15 between the smaller units 11. The same applies to the spaces 14 between the smaller units 11 and the outer jacket 10, where further smaller units 16 can be arranged. The points of contact 12 between the units 11 and, if appropriate, the units 16, 17 and the points of contact 13 with the edge can be connected by joining technology. Any remaining gaps can be poured out with ceramic material or covered with suitable shadow masks. It is also possible to insert the smaller units 11, 16, 17 into a perforated plate which corresponds exactly to the configuration shown in FIG. 1.

This schematic representation also applies in a similar way to irregularly bordered cross sections. In Figure 2, smaller units 21 and even smaller units 26, 27 are used to fill the predetermined cross-sectional area. Here, too, the contact points 22, 23 of the individual parts can be connected by means of joining technology and any remaining free spaces 24, 25 can be sealed by the means described above.
