摘　　要：用微秒级脉冲宽度和纳秒级脉冲电压电晕放电方法和颗粒计数测量原理,通过变量法研究了脉冲电晕场的脉冲宽度、脉冲频率与超细烟尘去除效率间的关系。研究表明:在实验条件下,脉冲宽度的增加可以提高除尘效率,臭氧的产生导致除尘效率的降低。相比脉冲宽度,脉冲频率对除尘效率的影响较大,在实验参数范围内,脉冲电晕场对超细烟尘(d=0.3 m)的净化效率能达99.5%以上。The relationship between the pulse width and pulse frequency of the pulsed corona field and the ultra-fine soot removal efficiency was investigated by the variable method using the microsecond pulse width and nanosecond pulse voltage corona discharge method and the particle counting measurement principle. Results showed that the removal efficiency of fine particles may reach above 99.5%(d=0.3 m)under experimental condition,and the removal efficiency was increase with pulse width increase,and the produce of ozone could decrease the removal efficiency,and the act pulse frequency was large.
