This article presents the methodology and results of experimental studies of the parameters of the electrode system “Potential plane with corona needles - grounded plane”. The parameters of the electrode system were determined for a distance between the electrodes of 0.15 m. The parameters of the electrode system determined on the basis of these studies were verified on the basis of experimental studies of the process of trapping dust particles from an air stream. The methodology and analysis of the results of these studies are given. Based on these studies, the best ratios of the parameters of the electrode system were determined according to the highest degree of purification of the cleaned air. The difference in the distances between the needles in a row located perpendicular to the flow of the cleaned air and between the rows of needles is determined.

This article provides an analysis of existing high voltage power supply devices for devices of electron-ion technology, in particular devices for cleaning gases from aerosol particles. Advances in this technology are described. The following are the disadvantages of the electric fields of a corona discharge when powered by a constant high voltage. To increase the efficiency of catching aerosol particles, the authors propose to combine self-sustained and non-sustained discharges in one discharge gap. To do this, it is proposed to use unipolar high-voltage pulses with a constant component and pulses with a duty cycle of more than 5. An analysis is made of the possibility of increasing the efficiency of the impact of electric fields when using circuits with two-sided power supply, the analysis of which makes it possible to increase the pulse repetition rate, as well as to regulate the process of the impact of electric fields on processed particles., regulation by the parameter of impulse voltage.

This article analyzes the existing ways of creating cold plasma at atmospheric pressure directly into atmospheric air. Research areas listed turns out to be very valuable from a practical point of view, since allows you to create in the plasma gas enough intense ultraviolet radiation, as well as high concentration of physically and biochemically active particles (metastable atoms and molecules, radicals, ozone and other reactive compounds) relatively small specific energy costs. Further in the article, a theoretical comparative analysis of the processes of ozone electrosynthesis in electric sinusoidal and pulsed electric fields is given. The revealed advantage of pulsed electric fields is confirmed by the results of experimental studies
