This application discloses a rectifying electrostatic precipitator, belonging to the field of dust collector technology. By sequentially setting a guide layer, a mixing layer, and a stabilizing layer in the inlet conical section of the outer shell, multiple airfoil-shaped guide elements in the guide layer evenly distribute the airflow, directing it across the entire inlet conical section of the outer shell. Multiple sets of grid holes in the mixing layer employ a staggered grid design to break up large-scale eddies in the flue gas guided by the guide layer, reducing them to smaller sizes and achieving initial velocity equilibrium. The stabilizing layer features a honeycomb open-cell design; the honeycomb structure effectively manages the airflow and stabilizes the velocity. Thus, the flue gas undergoes a three-stage process of "guidance-breakup-management" to achieve refined flow field treatment, improve velocity distribution uniformity, and reduce inlet local resistance.
