GAS EXCITATION DEVICE HAVING BRIDGED ELECTRODE AND GAS EXCITATION METHOD

摘要

An apparatus for exciting a gas, comprising at least a pair of electrodes connecting to an alternating current source in a housing having an inlet opening for a gas to be treated and an outlet opening for a gas which has been treated, characterized in that one electrode of the pair of the electrodes is a suspended electrode arranged by placing it under a tension at a predetermined position in the housing, the other electrode of the pair of the electrodes is a buried electrode arranged at a predetermined position by being buried in the holding wall of the housing at the end thereof,
an electrode portion of the buried electrode contains a linear or planar discharging portion as a whole, and
the electrode portion of the suspended electrode, opposed to the electrode portion of the buried electrode, has discharging portions where a distance from the electrode portion of the buried electrode becomes cyclically short.
