为更准确地描述粉尘粒子在电除尘器电场中的浓度分布,文章在现有电除尘器粉尘粒子沉降模型的基础上,通过引入影响因子的概念对改进的三维数学模型及其除尘效率估算方法进行了分析讨论,得到了不同精度下的除尘效率估算式和相应参数的估算方法.针对细粉尘,结合实验数据,得到预测其除尘效率时可以忽略竖直方向浓度变化,公式η=l-(e-l)e-al/fvω呵以在无特殊边界条件下进行效率估算.这些为电除尘器的设计和运行提供了一定的参考价值.

Based on the existing models of particle precipitation of electrostatic precipitators (ESPs), this paper discusses the improved 3-dimensionsal mathematic models and efficiency estimation methods for ESPs with a new concept of influ-encing factor. ESP efficiency formulas in different required precision and estimation methods of corresponding parameters were obtained, and the dust concentration change in vertical direction can be neglected according to the experimental re-sult. The efficiency formula obtained needn't any special boundary condition when being used.
