Electrostatic precipitators are currently most commonly used in industrial processes equipment to reduce dust emissions into the atmosphere. A significant impact on the process of extraction of two-phase gas/dust medium has the shape and configuration of the discharge electrodes, affecting the shape of the electric field in the chamber electrostatic precipitator. Geometric parameters of discharge electrodes and their arrangement in the chamber electrostatic should provide uniform current density distribution at the surface of the collecting electrodes. The article presents an analysis of the impact of geometry and configuration of industrial - blade type discharge electrodes on the distribution of current density on the collecting electrode. On the basis of the measure- ment results mathematical model was worked out which allows simulation of the current density distribution depending on the shape of the electrodes. The model allows to specify the most appropriate parameters of distance between the emission elements of discharge electrode and the distance between the electrodes. Preferred geometric parameters and configuration of discharge electrodes was determined by analyzing power spectral density magnitude (PSD) and the mean square value (RMS) of current density. The results indicate the possibility of reducing the number of elements of emission corona electrodes without worsening of the operating parameters of electrostatic precipitator.
