PROBLEM TO BE SOLVED: To enhance ultraviolet irradiation efficiency and suppress increase in size of the whole device.SOLUTION: An ultraviolet irradiation device includes: a flow passage through which a fluid to be treated flows; and a plurality of linear ultraviolet lamps which are disposed in the flow passage along one direction intersecting a flowing direction of the fluid to be treated, and are disposed in the flow passage at intervals from each other in a direction different from the one direction. The lengths of the plurality of ultraviolet lamps in one direction are different according to a distance where an inner wall of the flow passage faces in the one direction at each of positions of the plurality of ultraviolet lamps.SELECTED DRAWING: Figure 3

    【課題】紫外線の照射効率を高めると共に装置全体の大型化を抑制する。【解決手段】実施形態の紫外線照射装置は、被処理流体が流れる流路と、被処理流体の流れ方向に交差する一方向に沿って流路に配置され、かつ、一方向とは異なる方向に互いに間隔をあけて流路に配置された線状の複数の紫外線ランプと、を備える。複数の紫外線ランプの、一方向に対する長さは、複数の紫外線ランプの各位置において、流路の内壁が、一方向に対向する距離に合わせて異なる。【選択図】図3
