DISCHARGE TYPE GAS TREATMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a discharge type gas treatment device allowing start of discharge at a further lower voltage, and easy in controlling voltage to be inputtd for continuing discharge.

SOLUTION: This discharge type gas treatment device 10 is provided with a conductive electrode 15 having protrusions 15a; a counter electrode 16 facing the conductive electrode 15; a dielectric 17 covering the conductive electrode 15 side of the counter electrode 16; and a discharge power source 13 applying required voltage between the conductive electrode 15 and counter electrode 16 to generate discharge plasma for cleaning treating gas. The distance between the protrusions 15a and dielectric 17 is set to a required distance or less to start discharge from the vicinity of the protrusions 15a.
