Title:
MICROBUBBLE GENERATING NOZZLE
Document Type and Number:
WIPO Patent Application WO/2018/100915
Kind Code:
A1
Abstract:
[Problem] To provide a microbubble generating nozzle which greatly increases the generation rate of micro- and nano-level microbubbles. [Solution] A microbubble generating nozzle 1 is provided with: an introduction chamber 20 for introducing a gas-liquid mixture; a swirl chamber 30 for swirling the gas-liquid mixture L flowing out from the introduction chamber 20; a lead-out flow path 61 for leading out the swirling gas-liquid mixture L; a branch flow path 62 branching off from the lead-out flow path; and a circulation flow path 66 for circulating the gas-liquid mixture L, which has reached the downstream side of the lead-out flow path without flowing into the branch flow path, to the upstream side of the lead-out flow path 61. With the nozzle 1, microbubbles are generated by circulating the gas-liquid mixture L in which microbubbles have not been generated. Therefore, microbubbles can be generated in large quantities.
