磁约束作用对三电极ESP除尘性能的影响
Influence of Magnetic Confinement Effect on Dust-Removal Performance of Triple Electrodes ESP
摘要: 为了提高三电极静电除尘器(Electrostatic Precipitator, ESP)的除尘效率，本文在引入磁约束和建立多场耦合理论模型的基础上，采用FLUENT软件数值模拟磁约束作用下不同工作电压和烟气流速的PM2.5除尘效率，对比分析了不同磁场环境下三电极ESP对PM2.5的除尘效率。结果表明，随着磁场环境的增强，三电极ESP的除尘效率不断提高；引入磁约束作用后扩散荷电效应体现得相对较弱；磁约束作用在低工作电压和高烟气流速下对三电极ESP除尘性能的提升作用更大。研究结果可为新型线板式三电极ESP的性能提升和结构改造提供一定的参考价值。
Abstract: To improve the dust-removal efficiency of triple electrode electrostatic precipitator (ESP), based on the introduction of magnetic confinement effect and the establishment of multi-field coupling theoretical model, this paper uses FLUENT software to numerically simulate the dust-removal efficiency of PM2.5 under magnetic confinement effect with different working voltages and flue gas velocity. The results show that with the enhancement of the magnetic field environment, the dust-removal efficiency of the triple electrode ESP is continuously improved, and the diffusion charging effect is relatively weak after the introduction of magnetic confinement effect. The magnetic confinement effect has a greater effect on the dust-removal performance of triple electrode ESP at lower working voltage and higher flue gas velocity. The research results can provide some reference value for the performance improvement and structural modification of the new wire-plate triple electrode ESP.
