Description

Einrichtung zum Reinigen von Abgasen durch katalytische Nachverbrennung Die Erfindung betrifft eine Einrichtung zum Reinigen von Abgasen durch katalytische Nachverbrennung, bestehend aus einer zylindrischen Reaktionskammer mit darin angeordnetem Katalytelement sowie einem Röhrenwärmeaustauscher zum Aufheizen der zu reinigenden durch die gereinigten heißen Ab- gase.Means for purifying exhaust gases by catalytic combustion The invention relates to a device for purifying exhaust gases by catalytic combustion, consisting of gases of a cylindrical reaction chamber having arranged therein Katalytelement and a tubular heat exchanger for heating to be cleaned by the cleaned hot waste.

Von den bekannten Einrichtungen unterscheidet sich die Einrichtung nach der Erfindung dadurch, daß in der Reaktionskammer koaxial ein hohlzylindrisches Katalytelement und in diesem Hohlzylinder oder um ihn herum von den gereinigten Abgasen umströmte, von den zu reinigenden Abgasen durchströmte Wärmeaustauscherröhren vorzugsweise achsparallel angeordnet sind.The facility differs from the known facilities according to the invention in that a hollow cylindrical coaxially in the reaction chamber Katalytelement and in this hollow cylinder or around it from the cleaned Exhaust gases flowed around the heat exchanger tubes through which the exhaust gases to be cleaned flowed are preferably arranged axially parallel.

Es ergibt sich auf diese Weise eine Einrichtung von sehr gedrängter und für den Wärmeaustausch zwischen den gereinigten und den zu reinigenden Ab- gasen äußerst günstiger Bauart, denn die gereinigten Abgase beaufschlagen unmittelbar nach ihrem Austritt aus dem Katalytelement die Wärmeaustauscherröhren.The result is thus a means of very crowded and the heat exchange between the clean and the gases to be cleaned exhaust its convenient design, because the cleaned flue gases act on immediately after their exit from the Katalytelement the heat exchanger tubes.

Die Anordnung läßt sich auch so treffen, daß innerhalb eines Katalytelementes mit darum herum angeordneten Wärmeaustauscherröhren ein zweites Katalyteleinent koaxial angeordnet wird, in dessen Innenraum sich ebenfalls Wärmeaustauscherröhren befinden. Die bereits aufgeheizten Abgase strömen in diesem Fall aus dem Zwischenraum zwischen den beiden Katalytelementen teils radial nach außen, teils radial nach innen durch die Katalytelemente hindurch.The arrangement can also be made so that within a catalytic element a second catalyst element with heat exchanger tubes arranged around it is arranged coaxially, in the interior of which there are also heat exchanger tubes are located. In this case, the already heated exhaust gases flow out of the space between the two catalytic elements partly radially outwards, partly radially inside through the catalytic elements.

Nach einem weiteren Merkmal der Erfindung sind die Wärmeaustauscherröhren durch etwa radial gerichtete Leitbleche in Gruppen aufgeteilt. Auf diese Weise läßt sich bei entsprechender Lage der Reingasaustrittsöffnung in der Reaktionskammerwand ein Wärmeaustausch im Gegenstrom erzwingen.According to a further feature of the invention are the heat exchanger tubes divided into groups by approximately radially directed baffles. That way lets with a corresponding position of the clean gas outlet opening in the reaction chamber wall force a heat exchange in countercurrent.

Unter Wärmeaustauscherröhren sind selbstverständlich alle Gebilde von kanalartiger Erstreckung zu verstehen.Of course, all structures are under heat exchanger tubes to understand of channel-like extension.

Die Zeichnung zeigt schematisch einen Längsschnitt durch eine Einrichtung nach der Erfindung. Die zu reinigenden Abgase treten von unten in einen Teil der Reaktionskammer ein, der mit der eigentlichen Reaktionskammer nur durch die Wärmeaustauscherröhren 2 in Verbindung steht. Sie durchströmen diese Röhren nach oben, kehren dort (bei 5), gegebenenfalls nach Vermischung mit Heißgasen aus einer Brennkammer 4, ihre Richtung um, durchströmen das hohlzylindrische Katalytelement 6 und verlassen, nach Umströmen der Wärmeaustauscherröhren 2, die Reaktionskammer (Gasaustritt 7). The drawing shows schematically a longitudinal section through a device according to the invention. The exhaust gases to be cleaned enter a part of the reaction chamber from below which is only connected to the actual reaction chamber through the heat exchanger tubes 2. They flow through these tubes upwards, there (at 5), possibly after mixing with hot gases from a combustion chamber 4, reverse their direction, flow through the hollow cylindrical catalytic element 6 and, after flowing around the heat exchanger tubes 2, leave the reaction chamber (gas outlet 7).

Die Zusatzheizung 3 sowie der Abgasventilator 8 gehören nicht mit zur Erfindung.The additional heater 3 and the exhaust fan 8 do not belong to the invention.

Das Katalytelement 2 kann selbstverständlich auch aus bogenförmig gekrümmten Teilen zusammen- gesetzt sein oder die Form eines Polygons aufweisen. Das Wesentliche ist die kreissymmetrische bzw. quasikreissymmetrische Anordnung von Katalyte-lement und Wärmeaustauscher.The Katalytelement 2 can of course be also set from arcuately curved parts together or have the shape of a polygon. The essential thing is the circularly symmetrical or quasi-circularly symmetrical arrangement of the catalyst element and heat exchanger.
