Beschreibung
Zusammenfassung:	The invention relates to a method for online removing scaling of a catalytic range hood. The method comprises the steps that three-cyclone fine powder with the particle size smaller than or equal to 20 micrometers is added into a catalytic reaction regeneration system, the adding amount is 150-10000 mg/Nm < 3 > of smoke, and the temperature adjusting range of a range hood wheel disc is 260-350 DEG C. By means of the method, scale on the catalytic range hood can be removed online, and long-period operation of the range hood is guaranteed. 本发明涉及一种在线清除催化烟机结垢的方法。所述方法包括：在催化反应再生系统中加入粒度≤20μm的三旋细粉，加入量为150~10000mg/Nm3烟气，烟机轮盘温度调整范围为260~350℃。本发明所述方法可以在线清除催化烟机上的结垢，确保烟机长周期运行。
