Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Schutz von Katalysatoren und Bauteilen in Katalysatorsystemen vor Überhitzung und thermischer Zerstörung.The The invention relates to a device for protecting catalysts and components in catalyst systems from overheating and thermal destruction.
Bekannt
sind katalytische Abluftreinigungsanlagen mit Schüttungen
oder Waben als Adsorber oder Katalysator. Sie besitzen Waben- oder
Schüttschichtlagen und eine Heizzone, die elektrisch oder gasbeheizt
ist. Die eigentliche Katalysatorschicht oder Schichten, die der
Heizzone nachgeschaltet sind werden in Waben- oder Schüttschichtform
und deren Kombination ausgeführt. Die Heizschicht ist dabei,
beispielsweise, temperaturgesteuert auf die Reaktionstemperatur
der Katalysatoren zwischen ca. 100 und ca. 600°C. Das Prinzip
ist in einen Sonderdruck von cfi „
Der Nachteil dieser technischen Ausführung besteht darin, dass eine wirtschaftlich vertretbare technische Lösung zum Schutz vor Überhitzung von Bauteilen und der katalytischen Reaktionsfläche nicht gegeben istOf the Disadvantage of this technical embodiment is that An economically viable technical solution for protection not overheating components and the catalytic reaction surface given is
Ziel der Erfindung war es ein neues System zu finden, dass die Überhitzung des Katalysators verhindert und zwerlässig anzeigt, dass das System überhöhten Gastemperaturen ausgesetzt war.aim The invention was to find a new system that overheating prevents the catalyst and indicates impermissibly that the system is exposed to excessive gas temperatures was.
Die Erfindung besteht nun darin, dass nach dem Schadgaseingang im Katalysatorgehäuse eine Vorrichtung angebracht wird welche bei definierten Gastemperaturen eine Öffnung freigibt über die kühle Umgebungsluft den heißen Gasen zugemischt wird und heiße Gase durch die Öffnung entweichen können.The Invention is now that after the noxious gas input in the catalyst housing a device is attached which at defined gas temperatures an opening releases over the cool ambient air the hot gases is mixed and hot gases can escape through the opening.
Dies geschieht durch spezielle Materialien welche bei definierten Temperaturen abschmelzen oder abbrennen und eine Öffnung zur kühleren Umgebungsluft oder zu Kühlgasen freigeben.This happens through special materials which at defined temperatures melt off or burn off and an opening to the cooler Release ambient air or to cooling gases.

Das
kohlenwasserstoffhaltige Schadgas wird durch Heizeinrichtungen im

Ist
die Temperatur des Schadgases höher als die max. zulässige
Temperatur ist eine Temperaturreduktion des Gases notwendig um die
thermische Zerstörung der Bauteile zu verhindern. Die überhöhte Temperatur
des Gases bewirkt ein Ausschmelzen oder Zersetzen des Materials
