摘要
实验研究了非均匀电场中流化床状态气固混和体的直流电晕特性 ,观察了Al2 O3 气固混和体和聚丙烯气固混和体在不同极性、不同电压下的电晕波形。关于电压极性、占空比以及间隙距离对两种气固混和体起晕电压影响的实验发现 ,起晕电压随占空比增加而降低 ;正极性下Al2 O3 气固混和体的起晕电压比聚丙烯气固混和体低 。
The DC corona characteristic of the mixture of gas and solid in fluidized bed in non-uniform field is researched by experiment. The effect of voltage polarity, volume ratio and clearance of electrode gap on corona onset voltage of two types of mixture is studied respectively, and the corona current waveforms in different applied voltage are recorded. Experimental results show that the corona onset voltage decreases when the volume ratio increases; For positive polarity, the corona onset voltage of gas-Al 2O 3 mixture is lower than that of gas-polypropylene mixture, but in the case of negative polarity, the converse is true.
