Title:
極短パルス高電圧加電式ガス浄化方法
Document Type and Number:
Japanese Patent JP4828693
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To stably operate and obtain high cleaning performance without causing generation of sparks or the like even when an electric discharge inhibitory substance, such as moisture, exists in an exhaust gas while securing discharge electric power with which gaseous contaminants in the exhaust gas can be sufficiently cleaned in an ultra-short pulse high voltage applying-type gas cleaning apparatus. SOLUTION: When corona discharge is generated in a corona discharge system 8 having a discharge distance d, the discharge electric power to be charged per one ultra-short pulse high voltage is set to be >=d/200 (J) and <=d/5 (J) per unit length of corona discharge line and at least 90% of the discharge electric power is charged within 100 d (nanosecond) after applying pulse and thereafter the residual voltage in the corona discharge system 8 is allowed to be <=5 d (kV).
