摘　　要：分析了水煤浆的成分以及燃后飞灰性质对电除尘器的影响,并有针对性验证了旋风除尘器的预荷电作用,为模拟除尘装置的试验进一步提供了理论依据。笔者在该除尘模拟装置上,得出了3种电晕线的伏安特性曲线,经过分析比较,芒刺线有较好电晕效果。模拟实验结果也表明了,组合型式的除尘器能达到较高的除尘效率,这为进一步研发新型组合式除尘器开辟了一条新的道路。Firstly given in this paper are an analyze of the element of coal-water slurry, the influence of fly ash character from coal-water slurry combustion on electrostatic precipitator, and then the author purposefully proved that the air cyclone have the role of pre-charger for particles, which gave further more technical basis for the experiment of the simulation facility of the precipitator. Corona wires of three kinds are tested on the simulation facility, and then got three corresponding vohage-current curves. By compared and analyzed, the awned wire was considered to be best one. According to the result of the simulate test rig, the combined precipitator had higher collection efficiency, and totally adapt to the request of the present environment protect, which firstly give an access to study the new style of the combined precipitator.
