A roof type high-speed tunnel air cleaning system which is installed in a tunnel to clean air inside the tunnel is disclosed. The roof type high-speed tunnel air cleaning system includes a dust collecting block which collects tiny dusts contained in air flowing in through the damper unit and includes a plurality of dust collecting cells which each includes a honeycomb-type dust collecting tube and a protruding type discharge electrode. The honeycomb-type dust collecting tube has a hexagonal prism shape and is electrically grounded, and the protruding type discharge electrode is made of a metal plate which is relatively longer than the honeycomb type dust collecting tube, has protruding portions on both sides thereof, is electrically connected to a high voltage supplier, and is disposed at a center of the honeycomb type dust collecting tube. |
