Water is sprayed from a water nozzle (32, 33) of a water-washing device to wash polluted air in a painting booth (14), and then, a liquid polymer substance (57) having a character to adsorb a VOC is spayed from an adsorbent spraying nozzle (51 - 53) to remove the VOC from the air. Baffle (43 - 47) is provided in a discharge duct to prevent the VOC-contained mixed liquid mist from moving with the air. Namely, by causing the air to hit the baffle, the VOC-contained mist turns into drops. Through the water-washing by the water-washing device, VOC adsorption by the mixed liquid and mixed liquid mist removal by the baffle, the polluted air can be sufficiently purified. |
