FIELD: separation of solid particles from flow of dust-laden gases by means of a corona discharge, applicable in heat power, metallurgical, chemical and other branches of industry. SUBSTANCE: device uses at least one electrostatic precipitator, each of them has at least one field with a system of corona-forming and precipitating electrodes, sources supplying the electrostatic precipitators with direct and pulsed voltages, at least one blocking capacitor and current-limiting elements; the corona-forming electrodes of each field are divided at least into two groups connected through inductive elements, each group has at least one corona-forming electrode. When at least two electrostatic precipitators are used in the device and each of them has at least two fields with systems of corona-forming and precipitating electrodes, it is recommended to connect the electrode systems of the fields with the same ordinal numbers for each electrostatic precipitator in parallel. EFFECT: enhanced amplitude of pulsed voltage at simultaneous reduction of its duration. 2 cl, 1 dwg
