PLASMA TYPE GAS PURIFYING APPARATUS AND STREAMER DISCHARGE CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a streamer discharge-used plasma type gas purifying apparatus whose manufacturing cost is reduced by generating a streamer discharge without using a pulse power source. SOLUTION: Such a plasma reactor is used in this plasma type gas purifying apparatus that an acicular discharge electrode and a planar counter electrode are arranged oppositely almost in the state perpendicular to each other. A minute acicular projection (31) is arranged on the tip part (21a) of the discharge electrode. A DC power source for outputting DC voltage is used as the power source for impressing voltage between the discharge electrode and the counter electrode.
