To provide a compact device for generating fine bubbles excellent in such generating efficiency.SOLUTION: A fine bubble generation device S comprises: a gyration chamber A having a cylindrical wall face a1 and toric edge face a2; a gyration flow generating part B generating a gyration flow of flowing water in the gyration chamber A; a cylindrical restriction part C formed on the edge face a2 and having a bore smaller than that of the gyration chamber A; and an expansion chamber D provided near to a downstream side of the restriction part C and having a space expanded compared with an area of an outlet side opening of the restriction part C. In the device S, an inflow part c1 of the restriction part C is provided at a near side along the flowing water direction W toward the edge face a2 in a cross-sectional view by a flat surface including a shaft center X when defining a direction heading for the expansion chamber D from the gyration chamber A along the shaft center X of the restriction part C as the flowing water direction W.SELECTED DRAWING: Figure 3
【課題】微細気泡の発生効率が良いコンパクトな微細気泡発生装置の提供。【解決手段】円筒状の壁面ａ１と円環状の端面ａ２とを備えた旋回室Ａと、旋回室Ａの中に流水の旋回流を生成する旋回流生成部Ｂと、端面ａ２に形成され、旋回室Ａの内径よりも小さい内径を有する筒状の絞り部Ｃと、絞り部Ｃの下流側に隣設され、絞り部Ｃの出口側開口の面積に対して拡大した空間を有する拡張室Ｄと、を備え、絞り部Ｃの軸心Ｘに沿って旋回室Ａから拡張室Ｄに向かう方向を流水方向Ｗとするとき、軸心Ｘを含む平面による断面視において、絞り部Ｃの流入部ｃ１が端面ａ２に対して流水方向Ｗに沿った手前側に設けられている微細気泡発生装置Ｓ。【選択図】図３
