Description
Die Erfindung betrifft eine Einrichtung zur Abluftreinigung durch katalytische Nachverbrennung, die insbesondere zur Aufbereitung der Abluft von Räuchereien, Lackierereien und Lacktrocknungsanlagen einsetzbar ist.The invention relates to a device for exhaust air purification by catalytic afterburning, which can be used in particular for treating the exhaust air from smokehouses, paint shops and paint drying systems.
Die katalytische Nachverbrennung zur Behandlung von Abgasen wird bereits in vielfältigster Weise eingesetzt. Dabei spielen insbesondere wirtschaftliche Betrachtungen, wie der notwendige Luftdurchsatz, der Druckverlust, die benötigte Heizenergie für den Katalysator und die Auswahl des geeigneten Katalysators eine vordergründige Rolle.Catalytic afterburning for the treatment of exhaust gases is already being used in a wide variety of ways. Economic considerations such as the necessary air flow, the pressure loss, the heating energy required for the catalyst and the selection of the appropriate catalyst play a particularly important role.
Zur Verringerung des Energieeinsatzes werden u.a. Lösungen vorgeschlagen, die mit rotierenden regenerativen Wärmeübertragern arbeiten. Dabei wird eine sehr gute Wärmerückgewinnung erzielt. Nachteilig ist jedoch, daß bei relativ geringen Luftströmen die Größe der Einrichtung durch den notwendigen Durchmesser des Regenerators bestimmt wird, so daß derartige Einrichtungen verhältnismäßig groß sind, obwohl der Volumenstrom und die erforderliche Katalysatorgröße eine kleinere Baugröße ermöglichten.To reduce energy consumption, solutions are proposed that work with rotating regenerative heat exchangers. This achieves very good heat recovery. The disadvantage, however, is that with relatively low air flows, the size of the device is determined by the necessary diameter of the regenerator, so that such devices are relatively large, although the volume flow and the required catalyst size would allow a smaller size.
Für die Aufbereitung von Raumluft ist es auch bekannt, die katalytische Nachverbrennung mit Heizlüftern zu kombinieren. In diesem Falle wird die Wärme, die benötigt wird, um den Katalysator zu aktivieren, gleichzeitig zur Heizung der Gebäuderäume genutzt. Für die Abluftaufbereitung sind derartige Lösungen jedoch aus energetischer Sicht nicht einsetzbar.It is also known to combine catalytic afterburning with fan heaters for the treatment of room air. In this case, the heat required to activate the catalyst is simultaneously used to heat the rooms in the building. However, such solutions cannot be used for exhaust air treatment from an energy perspective.
Die Erfindung hat die Aufgabe, eine kompakte, möglichst kleine Einrichtung zur katalytischen Nachverbrennung zu schaffen, die mit relativ geringem Energieeinsatz zu betreiben ist und besonders für den Einsatz in kleineren Gewerbebetrieben, also zur Behandlung relativ kleiner Volumenströme geeignet ist.The invention has the task of creating a compact, as small as possible device for catalytic afterburning, which can be operated with relatively low energy consumption and is particularly suitable for use in smaller commercial enterprises, i.e. for the treatment of relatively small volume flows.
Diese Aufgabe wird durch die Merkmale der Schutzansprüche gelöst.This task is solved by the features of the protection claims.
Durch den Einsatz des Kreuzstromwärmeübertragers wird eine sehr gute Energiebilanz erreicht, so daß es möglich ist, nach einer bestimmten Betriebszeit das Heizregister abzuschalten bzw. die Energiezufuhr zu verringern.By using the cross-flow heat exchanger, a very good energy balance is achieved, so that it is possible to switch off the heating register or reduce the energy supply after a certain operating time.
An nachfolgendem Ausführungsbeispiel wird die Erfindung näher erläutert. In der Abbildung ist die erfindungsgemäße Einrichtung in einer Schnittdarstellung zu sehen.The invention is explained in more detail using the following exemplary embodiment. The figure shows the device according to the invention in a sectional view.
Das Gehäuse 1 besteht vorzugsweise" aus einer Innenummantelung aus Edelstahl, einer Isolierschicht und einer Außenummantelung aus Stahlblech. Als Isolierschicht können z.B. Keramikfasern eingesetzt werden.The housing 1 preferably consists of an inner casing made of stainless steel, an insulating layer and an outer casing made of sheet steel. Ceramic fibers, for example, can be used as the insulating layer.
Im oberen Bereich befindet 'sich* "der Kreuzstrom Wärmeübertrager 2. Über den Rohgaseintritt 3 wird die zu reinigende Luft in den Kreuzstromwärmeübertrager 2 eingeleitet und hat dabei z.B. eine Temperatur von 80 0C. nach Durchströmen des Kreuzstromwärmeübertragers 2 wird die Luft über das Heizregister 5 geführt und dabei auf ca. 350 0C erhitzt. Die nunmehr auf Zündtemperatur des Katalysators erwärmte Luft wird über den mit dem Katalysator ausgerüsteten Wabenkörper 6 zum Kreuzstromwärmeubertrager 2 geleitet und über den Reingasaustritt 4 ins Freie abgeführt. Beim Durchströmen des Kreuzstromwärmeübertragers 2 mit der aufgeheizten Luft wird die über den Rohgaseintritt 3 zugeführte Luft erwärmt. Die gereinigte Luft verläßt mit ca. 200 0C die Einrichtung.The cross-flow heat exchanger 2 is located in the upper area. The air to be cleaned is introduced into the cross-flow heat exchanger 2 via the raw gas inlet 3 and has a temperature of 80 ° C. After flowing through the cross-flow heat exchanger 2, the air is led over the heating register 5 and heated to approx. 350 ° C. The air, which is now heated to the ignition temperature of the catalyst, is led to the cross-flow heat exchanger 2 via the honeycomb body 6 equipped with the catalyst and discharged to the outside via the clean gas outlet 4. When the heated air flows through the cross-flow heat exchanger 2, the air supplied via the raw gas inlet 3 is heated. The cleaned air leaves the device at approx. 200 ° C.
Je nach Schadstoffgehalt der zu reinigenden Luft können unterschiedliche Katalysatoren eingesetzt werden.Depending on the pollutant content of the air to be cleaned, different catalysts can be used.
