| 摘要 |
A method for producing a high-voltage and low-intensity electrical discharge plasma, in which a gas to be treated is injected between a plurality of electrodes, the separation of which increases in the direction of movement of the gas and along which a succession of sliding arcs blown by the gas to be treated is produced, characterised by the use of a principal supply, at the mains frequency, connected to the principal electrodes, and of a high-voltage auxiliary supply connected to an auxiliary electrode and the maintaining of a low-intensity auxiliary pilot discharge between this auxiliary electrode and the principal electrodes, at a frequency which is triple that of the fundamental frequency of the mains. The invention is used in plasma chemistry and for treatment of polluted gases.
