FIELD: gas-discharge plasma technology.
SUBSTANCE: invention relates to gas-discharge plasma technology and technology, in particular to sources of plasma jets of atmospheric pressure, where the source gas is air or its mixture with other gases. The device includes a high-voltage power source, the discharge gap is formed by coaxially located inner high-voltage hollow cylindrical electrode 1 with a sharpened outer edge 3 facing the discharge gap d, and free electrodes in an amount of at least two placed on the outer surface of the dielectric insert 6 in the form of plates 2 with tips 5, facing the discharge gap d, and distributed at equal distances from each other, not exceeding the interelectrode distance. The high-voltage hollow electrode 1 is a nozzle for supplying air with a flow rate of up to 1.5 l/min.
EFFECT: increasing the plasma treatment zone, increasing the stability of the plasma jet to sharp fluctuations in the air in the environment and ensuring the arbitrary orientation of the plasma jets.
