Abstract
Apparatus and method for the treatment of pollutants in gases which includes a plasma reactor chamber having sawtooth electrodes through which said gases flow, a generator of high voltage pulses of short width, high repetition rate and rapid rise time being coupled to said reactor with matched impedance, causing pulsed streamer discharges to be initiated at said chamber electrodes, increasing the effective plasma volume for more efficient pollutant reduction.
Claims6
The method of treating pollutants in gases which comprises the steps of causing said gases to flow through a reactor chamber having sawtooth electrodes disposed therein, generating high-voltage pulses of short width, high repetition rate, and rapid rise time, and introducing said pulses to said reactor chamber, whereby pulsed streamer plasma discharges are initiated at said electrodes within said reactor chamber to increase the effective plasma volume and enhance pollutant reduction in said gases.
Apparatus for treating pollutants contained in gases, comprising a plasma reaction chamber, means causing said gases to flow through said chamber, a pulse generator, means for energizing said pulse generator to produce pulses of high voltage, high repetition rate, short pulse width, and rapid rise time, a plurality of sawtooth electrodes disposed in the path of flow of said gases in said chamber, and means for coupling said generator to said chamber whereby pulsed streamer discharges are initiated at said sawtooth electrodes to increase the effective plasma reaction volume therein and decompose said gases to reduce pollutants.
