BeschreibungDescription ;;
Katalysatoren finden in vielfacher Gestaltung auf unterschiedlichen Trägern zur Abgasreinigung Anwendung. Trotz des fortentwickelten Standes der Technik sind Katalysatoren zur Reinigung von Holz und Kohleofen bisher kaum verbreitet. Dies liegt zum einenCatalysts are used in a variety of designs on different substrates to clean exhaust gases. Despite the advanced state of the art, catalysts for cleaning wood and coal stoves are still rarely used. This is due, on the one hand, to
an der allgemein üblichen Wabenform der Katalyatoren (vgl. z.B. Corningwabe) , die zur Reinigung der Abgase eines Holzfeuers zwar grundsätzlich geeignet sind, bei der jedoch regelmäßig die Gefahr besteht - insbesondere bei unsachgemäßer Befeuerung - zu verstopfen. Die Reinigung der Abgase eines Kohlefeuers ist mit der Corningwabe gänzlich unmöglich;the generally used honeycomb shape of the catalysts (e.g. Corning honeycomb), which are basically suitable for cleaning the exhaust gases from a wood fire, but which regularly run the risk of clogging - especially if they are not properly lit. Cleaning the exhaust gases from a coal fire is completely impossible with the Corning honeycomb;
zum anderen ist die Anpassung der Wabenkörper an die verschiedenen Ofenformen nicht ohne größeren Aufwand und dementsprechender Kosten möglich;on the other hand, the adaptation of the honeycomb bodies to the different oven shapes is not possible without considerable effort and corresponding costs;
zuletzt ist diese Lösung in der Herstellung außerordentlich kostenintensiv, so daß sie wegen des verhältnismäßig hohen Kaufpreises vom Endverbraucher bisher nur in geringem Umfang angenommen wurde.Finally, this solution is extremely costly to manufacture, so that it has so far only been accepted to a limited extent by end consumers due to the relatively high purchase price.
Problemstellung : Problem :
Der in dem Patentanspruch zu Ziffer I angemeldeten Erfindung liegt das Problem zugrunde einen Katalysator zu bauen, der trotz des hohen Schwebstoffanteiles die Abgase eines Holz oder Kohlefeuers reinigt, nicht verstopft und kostengünstig an unterschiedliche Feuerstättensysteme angepaßt werden kann.The invention registered in the patent claim under item I is based on the problem of building a catalyst that, despite the high proportion of suspended matter, cleans the exhaust gases of a wood or coal fire, does not clog and can be adapted to different fireplace systems at low cost.
Lösung und erreichter VorteilSolution and achieved benefit ::
Die Lösung des Problems findet sich in den zu Ziffer 1. - 3. aufgeführten Merkmalen, in dem abweichend von den üblichen Kat-alysatorformen stabförmige Katalysatoren verwendet werden, die aufgrund ihres Abstandes zueinander nicht verstopfen können. Da die Katalysatorstäbe im oberen Flammenbereich aufgehängt sind, werden sie stark erhitzt. Diese hohe Temperatur bewirkt eine Nachverbrennung der hindurchströmenden Abgase im Bereich des Rauchdomes. Die Verbrennung wird durch die Zuführung von Sauerstoff verstärkt. Eventuell an den Katalysatorstäben anhaftende Schwebteile werden aufgrund der Temperatur der Katalysatorstäbe abgebrannt. Durch die in alle Richtungen bewegliche Lagerung der Katalysatorstäbe können diese sich ohne Spannung ausdehnen, wodurch ein Brechen oder Springen derselben vermieden wird.The solution to the problem can be found in the features listed under points 1 to 3. In contrast to the usual catalyst shapes, rod-shaped catalysts are used, which cannot become clogged due to their distance from one another. Since the catalyst rods are suspended in the upper flame area, they are heated to a high temperature. This high temperature causes the exhaust gases flowing through to burn in the area of the smoke dome. The combustion is enhanced by the supply of oxygen. Any suspended particles adhering to the catalyst rods are burned off due to the temperature of the catalyst rods. Because the catalyst rods can be moved in all directions, they can expand without tension, which prevents them from breaking or cracking.
Der gewählte Aufbau ist äußerst kostengünstig herzustellen und im Falle des Ausfalles eines oder mehrerer Katalysatorstäbe leicht und kostengünstig zu reparieren. Die Anpassung an verschiedeneartige Feuerstätten auch unterschiedlicher Größer ist durch die Vergrößerung oder Verkleinerung der Katalysatorstäbe und/oder deren Anzahl, unter Anpassung des Rahmenträgerteiles leicht und kostengünstig durchführbar.The chosen structure is extremely cost-effective to manufacture and, in the event of one or more catalyst rods failing, can be easily and inexpensively repaired. Adaptation to different types of fireplaces, including those of different sizes, can be carried out easily and inexpensively by enlarging or reducing the number of catalyst rods and/or their number, while adapting the frame support part.
Figur 1:Figure 1:
Figur 1 der Anlage 1 zeigt die Skizze eines Ausführungsbeispieles bezogen auf einen Ofen mit einem Umlenkblech der Größe 470 * 240 mm und einem Abgasrohrdurchmesser von 150 mm.Figure 1 of Appendix 1 shows a sketch of an embodiment based on a furnace with a baffle plate measuring 470 * 240 mm and an exhaust pipe diameter of 150 mm.
Ziffer 1 bezeichnet den Rahmen aus Winkeleisen 30 * 30 mm in einer Größe von 470 * 240 mm aus "St 37". Der Rahmen ist in einem Abstand von 25 mm eingeschnitten. Jede zweite der so ent-stehendenNumber 1 refers to the frame made of angle iron 30 * 30 mm in a size of 470 * 240 mm made of "St 37". The frame is cut at a distance of 25 mm. Every second of the resulting
Laschen ist schräg nach innen eingebogen, um ein Verrutschen der 11 Keramikstäbe zu verhindern.Tabs are bent diagonally inwards to prevent the 11 ceramic rods from slipping.
Ziffer 2 bezeichnet 11 Keramikstäbe mit einem Eisenoxidanteil von 2.% mit den Maßen 220 * 25 * 25 mm, die in einem Abstand von 25 mm in den Rahmen eingelegt sind. Die Stäbe sind in Längs- und Querrichtung ca. 1 mm beweglich.Number 2 refers to 11 ceramic rods with an iron oxide content of 2.% and the dimensions 220 * 25 * 25 mm, which are inserted into the frame at a distance of 25 mm. The rods can move approximately 1 mm in the longitudinal and transverse directions.
Figur 2:Figure 2:
Der Rahmen wird anstelle des Umlenkbleches entsprechend der Figur 2 in einen herkömmlichen Ofen eingesetzt. Hierdurch kommt es zu einer starken Erhitzung der Keramikstäbe, die wiederum eine Nachverbrennung der hindurchströmenden Abgase bewirkt.The frame is inserted into a conventional oven instead of the baffle plate as shown in Figure 2. This causes the ceramic rods to heat up considerably, which in turn causes the exhaust gases flowing through them to burn off.
Ziffer 3 bezeichnet ein Rohr, durch welches zusätzlich Sauerstoff in den Rauchdom geleitet wird. Hierdurch wird die Nachverbrennung verstärkt. Der ca 25 mm große Abstand zwischen den Keramikstäben verhindert ein frühes Verstopfen oder Versotten derselben. Durch die hohe Temperatur werden die Keramikstäbe von eventuell anhaftenden Schwebstoffen freigebrannt.Number 3 refers to a pipe through which additional oxygen is fed into the smoke dome. This increases the afterburning. The approx. 25 mm gap between the ceramic rods prevents them from clogging or sooting too quickly. The high temperature burns the ceramic rods free of any suspended matter that may be adhering to them.
