Experimental study on the removal of FCCS catalyst particles by the coupling interaction of the electrostatic field and flow field

Abstract

In this article, a dynamic electrostatic separation experimental device was set up. The experimental results show that with increasing packing height, inlet velocity and voltage, the saturated adsorption weight slowly increases. When the inlet velocity is greater than 2.379 × 10⁻⁴ m/s, the drag force plays the dominant role and the saturated adsorption weight decreases. The packing height and voltage are positive parameters for the separation efficiency, while the inlet velocity is a negative parameter. Through the nonlinear fitting of experimental data, the saturated adsorption weight, and dynamic electrostatic separation efficiency model of the device were obtained.
