Title:
MICROBUBBLE GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/212028
Kind Code:
A1
Abstract:
The present invention relates to a microbubble generation device which can generate microbubbles with a high microbubble concentration in a liquid and a small bubble diameter. The device is characterized by being provided with: a bubble generator that comprises a tube body having an internal liquid flow path, a liquid inlet for introducing a liquid into the flow path, a gas inlet for introducing a gas into the flow path, and an outlet for discharging a gas-liquid mixture from the flow path; and a gas supply means that has a gas supply port for supplying pressurized gas to the bubble generator. The flow path in the bubble generator extends from the liquid inlet to the outlet in a substantially coaxial line. Multiple reduced-diameter portions, in which the inner diameter is reduced towards the flow direction of the liquid, are provided in the flow path. Gas-liquid mixing units that have an inner diameter larger than the smallest inner diameter in the reduced-diameter portions are provided continuously downstream of the reduced-diameter portions. Near the reduced-diameter portion provided furthest downstream in the flow path, the gas inlet of the bubble generator is provided as multiple through-holes arranged along the circumferential direction of the outer wall of the tube body, and the gas inlet communicates with the gas supply port of the gas supply means.
