Abstract

Bei einer Anlage zum Entsticken von Rauchgas mit einem Katalysatorkörper (1) mit einer im Wesentlichen als ebene Fläche (10) ausgebildeten Einströmseite (11) an die die Rauchgase (2) anströmen können, einer Ausströmseite (12), einer Vielzahl von von der Einströmseite in Richtung zur Ausströmseite vom Rauchgas durchströmbaren Längskanälen (13) und einer Abblasvorrichtung (3) zum Blasen eines Fluids über die Einströmseite, erkannt, dass auf die beweglichen Rußbläser, die eine aufwändige Mechanik zum Verfahren sowie hohe Luftmengen benötigen, verzichtet werden kann, wenn Ausblasöffnungen zum Ausblasen des Fluids, hier Luft, entlang der durch die Einströmseite ausgebildeten ebenen Fläche angeordnet sind. Bei geeigneter Dimensionierung der Öffnungen (31) zum Erzielen der notwendigen hohen Fluidgeschwindigkeiten wurde erkannt, dass auch mit im Vergleich zum Rußbläser geringe Fluidmengen und ohne Verfahren der Abblasvorrichtung über große Entfernungen Stäube von der Einströmseite abgeblasen werden können. Im Gegensatz zu Rußbläsern wird hierbei auf hohe Fluidgeschwindigkeiten und kurze Zeiten gesetzt. Es wurde erkannt, dass kurze Fluidstöße, vorzugsweise mit Schallgeschwindigkeit, ausreichend sind, um große Flächen zu reinigen.

In a system for de-stoking flue gas with a catalyst body (1) having a substantially flat surface (10) formed inflow side (11) to which the flue gases (2) can flow, an outflow side (12), a plurality of from the inflow side in the direction of the outflow side of the flue gas flow-through longitudinal channels (13) and a blower (3) for blowing a fluid on the inflow side, recognized that can be dispensed with the soot blowers who require a complex mechanism for the method and high air volumes, if exhaust ports for blowing out the fluid, here air, are arranged along the plane formed by the inflow side flat surface. With suitable dimensioning of the openings (31) to achieve the necessary high fluid velocities, it was recognized that dusts can be blown off the inflow side over long distances, even with small quantities of fluid compared to the sootblower and without blower. In contrast to sootblowers, high fluid speeds and short times are used here. It has been recognized that short bursts of fluid, preferably at the speed of sound, are sufficient to clean large areas.
