• 摘要：电晕线雾化半湿式除尘技术是在传统的荷电水雾除尘技术基础上发展起来的它不需要专门另设雾化装置，而是采用电除尘器的电晕线直接使水雾化并荷电.使水沿垂直设置的电晕线流下并在电晕线表面形成水膜.由于电晕线表面高场强电场的作用，水膜破裂形成带电水滴.经收尘电场的加速后，水滴以高速冲击极板.

• Abstract：A semi-set precipitation technology with atomized water droplets by corona wire was introduced. The atomization characteristics and precipitation function were researched. Study in laboratory and on industrial sites has shown that this technology has outstanding precipitation effect for rnany kinds of non-easy precipitated dusts.

• Key words：precipitation  atomized water droplets
