<p><P>PROBLEM TO BE SOLVED: To provide an electric dust collecting installation for a highway tunnel, which is installed in a headroom of the tunnel by aiming a miniaturization of an electric dust collector and devising an arrangement of the electric dust collector, and at the same time, in which the purified air is blown out on a carriage way portion at a low speed to improve remarkably an effect of a visual environmental improvement, by which no enlarging of a tunnel bore diameter is required, and civil engineering costs can be decreased. <P>SOLUTION: In the electric dust collecting installation for the highway tunnel, at the headroom X inside the highway tunnel T, an electric dust collector 2 is installed suspending from a traveling rail 3 fixed on a ceiling through a chain block 4 so that air flows in a direction perpendicular to a longitudinal direction, the exhaust inside the highway tunnel T is suctioned from an upper side and purified by the electric dust collector 2, the purified air is guided by an air supplying duct 7 so as to be blown out from an intake port 7b to a downward carriage way portion 14. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
