APPARATUS FOR CLEANING AIR IN TUNNEL AND TUNNEL INTERIOR PANEL USED THEREIN

摘要

PROBLEM TO BE SOLVED: To remove a pollutant in a tunnel and to keep visual environment while cleaning air. SOLUTION: A tunnel interior containing titanium dioxide formed to the surface thereof, a light source apparatus 2 irradiating the surface of the tunnel interior panel 1 with ultraviolet rays in order to catch a pollutant in air by activating titanium dioxide and a washing device 3 washing off the pollutant caught by the surface of the tunnel interior panel 1 are attached to the side wall of a tunnel T and a pollutant such as nitrogen oxide or sulfur oxide generated by exhaust gas of a vehicle or the abrasion powder of a tire is oxidized to nitric acid or sulfuric acid by strong oxidizing power developed by activating titanium dioxide of the outer layer to be caught and removed by the surface of the tunnel interior panel 1.
