A model for computing the trajectory of conducting particle from waste printed circuit board (PCB) scraps in corona electrostatic separator is established. Using analytical expression for computing non-uniformity of the electric field in the active zone of the separator and the differential method were used for computing the trajectories of conducting particles in the air, after detachment. The result shows that the trajectory of conducting particle can be computed under various initial parameters (R, r, L, alpha, U, n; rho, r0) by the computing model and the computing results have a good agreement with the actual separating process. This model offers a possible for designing the new corona electrostatic separator.
建立了一种用于计算电晕静电分离器中废弃印刷电路板（PCB）碎片上导电颗粒轨迹的模型。利用计算分离器有效区内电场不均匀性的解析表达式，并采用微分法计算导电颗粒在空气中脱离后的轨迹。结果表明，通过该计算模型可以在各种初始参数（R、r、L、α、U、n；ρ、r0）下计算导电颗粒的轨迹，计算结果与实际分离过程吻合良好。该模型为新型电晕静电分离器的设计提供了一种可能。
