(57) [Summary] (Modified) [Purpose] A pollution gas purification unit is attached to at least a part of a building or pillars constructed outdoors to construct an air pollutant purification device. A structure having an inlet 22 and an outlet 24 in at least a part of a building or a pillar constructed in the field and including a plasma generating mechanism 27 and a fan 28 therein, and the fan and / or the housing. An air pollutant purification device comprising a gas purification unit having a metal layer 30A having a catalytic action formed on the inner wall surface. Since this device is mainly installed outdoors, it can be used as a power source for a fan by using a solar cell as a power source, and can generate plasma by applying a high frequency voltage through an inverter. it can. Platinum, palladium, ruthenium, rhodium and the like are preferably used as the metal having a catalytic action. |
