声波吹灰器主要由压缩气源、电子控制器和声波发生器组成。压缩空气经声波发生器转换成声能 ,在电子控制器控制下 ,声波以一定的频率、工作程序和周期进入炉内。声波以直射、渗透、反射和绕射等形式反复作用于管子表面的积灰 ,使积灰和焦渣产生疲劳而疏松、脱落。从大坝发电厂、锦州发电厂使用声波吹灰器的效果看 ,受热面管各侧的表面都很干净 ,没有浮尘、硬焦渣堆积 ;锅炉热效率提高 ;节约运行费用。旧锅炉改造时 ,若用声波吹灰器代替蒸汽吹灰器 ,经过经济分析 ,很快可收回投资。
Sonic soot blower is mainly composed of compressed air source, electronic controller and sound wave generator. The compressed air is converted into acoustic energy by the sound wave generator. Under the control of the electronic controller, the sound waves enter the furnace with a certain frequency, working procedures and cycles. Sound waves in the form of direct, infiltration, reflection and diffraction repeatedly act on the surface of pipe fouling, fouling and coke slag fatigue and loose, fall off. From the dam power plant, Jinzhou power plant soot blower effect, the surface of the heating surface tube is very clean, no dust, hard coke accumulation; boiler thermal efficiency; saving running costs. When the old boiler is retrofitted, if the soot blower is used instead of the steam sootblower, the investment can be recovered soon after economic analysis.
