摘　　要：研究了高压静电电压对除尘效率的影响。无论是在变化板间距还是变化板间电压的情况下,静电除尘器的除尘效率都能够达到90%以上;当最大板间距、电压为32 kV时出现最大捕集效率为99.66%。静电除尘器在空载和负载时的伏安特性曲线趋势基本一致,均在9 kV左右开始出现电流陡增,随着电流迅速增大,二者均在20 kV左右开始出现闪络。The effect of high voltage electrostatic voltage on dust removal efficiency is studied.The dust removal efficiency of ESP can reach more than 90%,no matter the spacing of plates or the voltage between plates is changed.The maximum trapping efficiency is 99.66%when the maximum plate spacing and voltage are 32 kV.The volt-ampere characteristic curves of ESP under no-load and load are basically the same.Current increases sharply at about 9 kV,and flashover occurs at about 20 kV with the rapid increase of current.
