A wire-to-wire type nonthermal plasma reactor with ferroelectric pellet barrier

A new wire-to-wire type of discharge plasma reactor with ferroelectric pellet barrier has been proposed and investigated experimentally. It was found that there were intense microdischarge currents taking place on the AC corona-charged surfaces of the ferroelectric pellet barrier. These surfaces were placed on the bottom wire electrode in the reactor. This type of nonthermal plasma reactor was found to generate a corona discharge twice per half cycle of the applied AC high voltage, once from the upper corona wire and again from the surface of the pellet barrier. As a result, the proposed plasma reactor has the potential to greatly increase ozone production and may find use as an effective means for removing pollutant gases.
