FINE BUBBLE GENERATOR
PROBLEM TO BE SOLVED: To provide a fine bubble generator enabling fine bubbles generated in liquid to maintain a stable bubble diameter even after the liquid passes through a venturi.SOLUTION: A fine bubble generator 1 in which air 11 supplied into liquid 10 is collapsed to miniaturize bubbles by a venturi 3, includes, on a cross section center part of a passage 4 on the downstream side of the venturi, a flow adjusting member 5 for changing a liquid flow a little to the pipe wall 6 side, and for adjusting so that a flow velocity of the liquid on a pipe wall part is not changed from a flow velocity of the liquid after passing through the venturi.SELECTED DRAWING: Figure 1
【課題】液体がベンチュリ通過後も、液体に発生させた微細気泡を安定した気泡径で維持させることが可能な微細気泡発生装置を提供すること。【解決手段】液体１０に供給された空気１１をベンチュリ３により圧壊して気泡を微細化する微細気泡発生装置１であって、ベンチュリの下流側の流路４の断面中央部に、液体の流れを管壁６寄りに変更させ、管壁部分の液体の流速をベンチュリ通過後の液体の流速から変化しないように調整する流れ調整部材５を備える。【選択図】図１
