摘要
The present invention relates to an air suction structure mounted on an exit of a tunnel for vehicles applicable to a tunnel air purifying system which sucks in air containing harmful materials such as fine dust, nitrogen oxide (NOX) gas, a volatile organic compound (VOC), ozone, etc. inside a tunnel generated by vehicles driving in the tunnel at an exit of the tunnel to purify the air and then discharge the air to the atmosphere. The air suction structure mounted on an exit of a tunnel for vehicles comprises: an extension tunnel unit fixed on an exit of a tunnel for vehicles to extend the exit of the tunnel; a plurality of air suction units fixed on the extension tunnel unit and exposed to an internal space of the extension tunnel unit to suck in polluted air discharged through the exit of the tunnel for vehicles; and a duct unit comprising a plurality of ducts which connect the plurality of air suction units and are connected to a polluted air transport unit. A tunnel air purifying system using an internal purifying method can be realized without a bypass tunnel required for a conventional tunnel air purifying system. Since a bypass tunnel is not required, construction costs for the tunnel air purifying system can be drastically reduced by 70% or more. The air suction structure mounted on an exit of a tunnel for vehicles allows the tunnel air purifying system using an internal purifying method to be additionally installed on an already constructed tunnel designed to use a ventilation method. Energy efficiency of the tunnel air purifying system can be increased by photovoltaic energy generation.
