对一种不使用电晕放电的电除尘器进行了研究。电除尘器采用两级结构，由感应充电式颗粒充电器和平行板式颗粒收集器组成。通过施加几kV的高电压，在该电压下，在充电器中不产生电晕放电，由于与充电器电极接触，颗粒通过感应充电。带电粒子上的电荷量随着所施加的电压和充电器中的湍流空气流而增加。使用环境空气研究了配备有感应充电器的ESP的性能。当所施加的电压足够低而不产生电晕放电时，直径在0.3 μ m至5 μ m范围内的颗粒的去除效率随着所施加的电压和充电器中的气流的湍流强度而增加。这表明感应充电可用于静电除尘，这可以显著减少臭氧产生和功耗。
An electrostatic precipitator (ESP) without using corona discharge was investigated herein. The ESP employed a two-stage configuration, consisting of an induction charging-based particle charger and a parallel plate type particle collector. By applying a high voltage of several kV, under which no corona discharge was generated in the charger, particles were charged by induction due to contact with charger electrodes. The amount of charge on the charged particles increased with the applied voltage and turbulent air flow in the charger. Performance of the ESP equipped with the induction charger was investigated using ambient air. The removal efficiency for particles ranging 0.3 mu m to 5 mu m in diameter increased with applied voltage and turbulence intensity of gas flow in the charger when the applied voltage was sufficiently low not to generate corona discharge. This suggests that induction charging can be used for electrostatic precipitation, which can reduce ozone generation and power consumption significantly.
