A barrierless pulse discharge cell

Abstract

A barrierless plasmachemical ozone generator, operating on the corona discharge, is studied. A high-voltage pulse power source and a discharge chamber are its basic elements. For obtaining high-voltage pulses with duration of several tens nanoseconds, a rotating discharger is connected to the output of a highvoltage direct-current source. The studied barrierless discharge chamber is characterized by a high efficiency of ozone synthesis, design simplicity, and minimal sizes. As compared to discharge chambers of other types, its advantage is that a corona discharge virtually fully fills its volume. Due to this fact, ozone is synthesized almost in the whole volume of the discharge chamber, resulting in attaining its high concentration at the chamber output. A productivity equal to 30 g/m³ and higher was reached in the experiments.
