摘要

对尖头电极静电除尘器的特性进行了数值研究。在这项研究中，静电除尘器中出现了复杂的电流体力学流动，并形成了涡流，最大气体流速为 30.9 m/s。尖刺电极对电场和电荷密度的分布有显著影响。电晕电荷被限制在尖刺电极尖端周围的六个半椭圆形区域，在尖端表面的电荷密度为 1.04 × 106 μC/m3。粒子轨迹因 EHD 流动而变得复杂。高工作电位和低气体速度有利于颗粒的去除。

Numerical simulation of spiked electrode electrostatic precipitator

The characteristic of the spiked electrode electrostatic precipitator was numerically studied. Complicated electrohydrodynamic flow was observed and vortices were formed in the ESP with the maximum gas velocity 30.9 m/s in this study. The spiked electrode had significant effects on the distribution of electric field and charge density. The corona charge was confined to six semi-ellipsoidal regions around the tips of the spiked electrode, which was 1.04 × 10⁶ μC/m³ at the tip surface. The particle trajectories were complicated due to the EHD flow. High working potential and low gas velocity were beneficial to the removal of particles.
