<p>The present invention provides an apparatus to purify air in a tunnel comprising: a dehumidifier installed inside a tunnel to remove moisture in the air inside a tunnel; a dust collector connected to the dehumidifier to remove fine dust in the air flowed from the dehumidifier; a catalytic reactor connected to the dust collector to remove carbon monoxide in the air flowed from the dust collector by a catalytic reaction; a plasma reactor connected to the catalytic reactor to remove a volatile organic compound in the air flowed from the catalytic reactor through a corona discharge; and an air blower to generate the suction force to sequentially transfer air to the dust collector, the catalytic reactor, and the plasma reactor after the air inside the tunnel is flowed through the dehumidifier. In the apparatus to purify air in a tunnel, air whose moisture and fine dust are removed through the dehumidifier, and the dust collector passes through the catalytic reactor and the plasma reactor. Therefore, air discharged to the outside of the tunnel is at a state where carbon monoxide is removed in accordance to the catalytic reaction of the catalytic reactor, and a volatile organic compound is decomposed and removed in accordance to the corona discharge of the plasma reactor.</p> |
