摘要： A two-stage electrostatic separator for separating particles from a particle laden gas stream includes a pre-charging section and spaced-apart gas-permeable grounded and discharge electrodes charged at opposite polarities and defining a separating section between them, the grounded electrode being positioned upstream from the discharge electrode. The particles in the particle laden gas stream are pre-charged to a certain charge in the pre-charging section and penetrate through the grounded electrode into the separating section, where the particles are separated from the particle laden gas stream. As a result, a clean gas stream exits from the separating section through the discharge electrode, and the particles separated from the particle laden gas stream are partially collected on the grounded electrode, and partially are removed with a bleed flow which is recirculated. The electrodes may be of linear or cylindrical shape, and linear electrodes may be arranged in a "zig-zag" order.

摘要翻译： 用于从载有颗粒的气流分离颗粒的两级静电分离器包括预充电部分和间隔开的透气的接地和放电电极，其以相反极性充电并且在它们之间限定分离部分，接地电极位于上游 从放电电极。 载入颗粒的气流中的颗粒在预充电段中预充电到一定电荷，并穿过接地电极进入分离段，在该分离段中颗粒与载有颗粒的气流分离。 结果，清洁的气流通过放电电极从分离部分排出，并且从载有颗粒的气流分离的颗粒被部分地收集在接地的电极上，并且部分地被再循环的排出流除去。 电极可以是直线形或圆柱形，并且线状电极可以以“之字形”的顺序排列。
