FINE BUBBLE GENERATOR
To provide a fine bubble generator which can generate a sufficient amount of nano-bubbles with a simple configuration.SOLUTION: A fine bubble generator includes a roughly cylindrical body part 10, a liquid introduction part 20 formed on a first end 11 on a liquid flow-in side and a through hole 30 communicating with the liquid introduction part 20, in which the liquid introduction part 20 has a circular opening 25 and has a cross-sectional area gradually reduced toward a second end 12 from the first end 11 of the body part 10, the through hole 30 is formed of a central region 31 including the narrowest part and a first peripheral region 32 and a second peripheral region 33 that are formed symmetrically with respect to a central axis L1 and include the widest part, in an arbitrary cross section vertical to the central axis L1 of the body part 10, the central region 31, the first peripheral region 32 and the second peripheral region 33 are communicated by a continuous curve, and the cross section regulating the through hole 30 is rotated at least 270 degrees toward the second end side 12 from the first end side 11 in the central axis L1 direction.SELECTED DRAWING: Figure 2
【課題】簡単な構造でありながら、十分な量のナノバブルを発生しうるファインバブル発生装置を提供する。【解決手段】略円筒状の本体部１０と、液体が流入する側の第１端部１１に形成された液体導入部２０と、液体導入部２０と連通する貫通孔３０とを備え、液体導入部２０は、円形の開口２５を有し、本体部１０の第１端部１１から第２端部１２に向かって徐々に断面積が減少し、貫通孔３０は、本体部１０の中心軸Ｌ１に垂直な任意の断面において、最も幅の狭い部分を含む中心領域３１と、中心軸Ｌ１に対して対称に形成され、最も幅の広い部分を含む第１周辺領域３２及び第２周辺領域３３とで形成され、中心領域３１と第１周辺領域３２及び第２周辺領域３３は連続した曲線で連通され、貫通孔３０を規定する断面は、中心軸Ｌ１方向に沿って、第１端部側１１から第２端部側１２に向かって少なくとも２７０度回転している。【選択図】図２
