Summary:PROBLEM TO BE SOLVED: To improve collection performance of paint mist.SOLUTION: An air duct 4 and a cyclone 5 are provided between a paint booth body 1 comprising a water washing wall 11, and a fan 3 for sucking air 2 in booth, which is guided through a lower side of the water washing wall 11. The air duct 4 makes a channel cross sectional area narrow, for enhancing flow speed of the air 2 in booth, then flows the air in booth into the cyclone 5. The cyclone 5 is configured to flow the air 2 in booth from the air duct 4 from a direction along a tangential direction of an outer cylinder 22, into a cylindrical space 28 between the outer cylinder 22 and an inner cylinder 26, for forcibly forming a revolving flow. To the air duct 4 and the cyclone 5, water films 7c, 7e and 7f and pole-state water streams 7d and 7g flow down from a water flow-down device 6. The paint mist contained in the air in booth, is collected by centrifugal separation action on the cyclone 5 and suction and capturing of the respective water films 7c, 7e and 7f and the respective water streams 7d and 7g on the air duct 4 and cyclone 5.SELECTED DRAWING: Figure 1 【課題】 塗装ミストの回収性能を向上させる。【解決手段】 水流壁１１を備えた塗装ブース本体１と、水流壁１１の下方を通して導かれるブース内空気２を吸引するための排風機３との間に、空気ダクト４とサイクロン５を設ける。空気ダクト４は、流路断面積を絞ることでブース内空気２の流速を高めてからサイクロン５へ流入させるものとしてある。サイクロン５は、外筒２２と内筒２６との間の円筒状の空間２８に、空気ダクト４からのブース内空気２を外筒２２の接線方向に沿う方向から流入させて旋回流を強制的に形成するようにしてある。空気ダクト４とサイクロン５には、水流下装置６により、水膜７ｃ，７ｅ，７ｆと柱状水流７ｄ，７ｇを流下させる。ブース内空気に含まれる塗装ミストは、サイクロン５での遠心分離作用と、空気ダクト４とサイクロン５における各水膜７ｃ，７ｅ，７ｆと各柱状水流７ｄ，７ｇによる吸着、捕集によって回収する。【選択図】図１
