Abstract
A fine bubble generator may include an inlet into which gas-dissolved water in which gas is dissolved flows, an outlet out of which the gas-dissolved water flows; and a fine bubble generation portion disposed between the inlet and the outlet. The fine bubble generation portion may include a venturi portion including a diameter-reducing flow path and a diameter-increasing flow path, wherein a flow path diameter of the diameter-reducing flow path reduces from upstream to downstream, and the flow path diameter of the diameter-increasing flow path increases from upstream to downstream, a discharging flow path configured to discharge the gas-dissolved water, which flowed out of the venturi portion, out of the fine bubble generation portion; and a recirculation flow path connecting a midstream of the outflow path and the venturi portion.
