Abstract
PURPOSE: To produce an effective removal effect in a subject method which removes solid adhered to a catalyst bed by the aid of air current flowing at a rapid speed into an exhaust gas denitrating device by providing a long slit nozzle throughout almost a full length of an injection pipe, and injecting a continuous air stream therefrom.
CONSTITUTION: Denitration catalyst beds 1, 1' consist of catalyst blocks having a honeycomb-shaped perforation, and gas to be treated is exhausted through an outlet 9 after it passes through the catalyt bed 1, 1' successively. A part of solid, contained in the exhaust gas 3, adheres to the inlet edge surfaces and catalyst surfaces 2. A soot blow device, which is fitted into a guide material 13 and in which an injection pipe 10 can move in the direction of an arrow mark 8 parallel to the catalyst bed, is mounted in front of the catalyst bed. A pressurized air supplied from a feed pipe 6 is jetted to the catalyst surface through a slit nozzle 7 formed in the injection pipe 10 to remove extraneous matter. In this method, the pressurized air is injected uniformly, whereby the injection pipe can approach closer to the catalyst surface and the consumption amount of air can be reduced.
