METHOD FOR REMOVING HARMFUL GAS AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a high-performance, compact and inexpensive device for removing harmful gases and to provide its method. SOLUTION: This device for removing harmful gases from a gas contg. the harmful gases has a photocatalyst and a light source 10 for irradiating the photocatalyst with light. Electric field forming electrodes 8 and 9 are provided in the device, the photocatalyst is arranged on at least a part of the positive electrode 8, the intensity of the electric field is preferably controlled to 10V/cm to 5kV/cm, and the positive electorode between the electric field forming electrodes is preferably formed by coating many rod-shaped or fiber- shaped carriers consisting of quartz glass with the surface roughened or a comblike carrier consisting of ceramic with a transparent conductive material and a photocatalyst.
