Apparatus for treating pollutants, aerosols and odor-producing materials in ionic wind comprises mesh electrodes to produce plasma, electrodes being mounted in housing and ionic wind flowing through space between it and electrodes

The invention relates to the field of plasma cleaning of exhaust gases and exhaust air.
A method for treating aerosols, pollutants and odorous substances in the ion wind, characterized in that at least one side of plasma electrodes (3a, 3b) facing the gas space is acted upon with positive or negative pulse voltages, a housing (1), a separate extraction electrode or a further plasma electrodes (3a or 3b) for ion extraction and / or deposition and / or decomposition are connected in such a way that a potential difference is established and ions are extracted from the area of the plasma electrodes (3a, 3b) and accelerated in the field, and that in the gas existing aerosols are charged and transported to the housing (1), to a separate extraction electrode upstream of the housing (1) or to a further plasma electrode (3a, 3b).
