Collecting plate is the core component of the electrostatic precipitator. In order to explore the influences of the plates shape and electrode configuration on the particle precipitation process, numerical models of an ESP with seven different types of collecting plates were established and calculated. The simulation results showed that the shape of the collecting plate did have a great impact on the electric field, airflow particles movement. From the perspective of electric field characteristics, the space current density and electrostatic shielding effect in multielectrode ESPs varied with the shape of the plates under the same supply voltage. When using C-type plate, the shielding effect was minimal and the current density distribution of the plate was more uniform. When it comes to airflow distribution, small vortex structures were easily generated near the plates when the CW type, the rod-curtain and Z-type plates were used, leading to particle re-entrainments. In terms of collection efficiency, the C-type plate enjoyed the highest efficiency, while the ZT-type and corrugated plate were less efficient.

集电板是静电除尘器的核心组件。为了探索板的形状和电极配置对颗粒沉淀过程的影响，建立并计算了具有七种不同类型的收集板的ESP的数值模型。仿真结果表明，集电板的形状确实对电场，气流颗粒的运动有很大的影响。从电场特性的角度来看，在相同的电源电压下，多电极ESP中的空间电流密度和静电屏蔽效果会随板的形状而变化。当使用C型板时，屏蔽效果最小，并且板的电流密度分布更均匀。关于气流分配，当使用CW型，棒型帘式和Z型板时，在板附近容易产生小的涡旋结构，从而导致颗粒重新夹带。就收集效率而言，C型板效率最高，而ZT型和波纹板效率较低。
