三电极电除尘器的电流特性

Current Characteristics in Tri-electrode Electrostatic Precipitators

电除尘器是大气污染控制领域中能够有效捕集超细粒子的主要设备之一.本文研究了三电极结构电除尘器内的电极参数对电流分布特性的影响.结果表明,三电极结构中的收尘极距可取普通板式电除尘器中的相应值,而实用中过大的线极距也是没有必要的.

Electrostatic precipitator is one of the main devices for collecting ultra-fine particles in air pollution control field. The distribution of corona current in a tri-electrode electrostatic precipitator is experimentally investigated in the present paper. The experimental data show that the width of the cross channel should take the same magnitude as in wire-duct electrostatic precipitators, and large wire-to-wire spacing is not necessary in application.
