FIELD: nanotechnologies.
SUBSTANCE: invention relates to a nozzle generating nanobubbles and a nanobubble generator for producing a liquid containing nanobubbles which are small bubbles. Generator (100) of nanobubbles contains nozzle (1) generating nanobubbles. Nano-bubble generating nozzle (1) comprises input portion (11) for feeding mixed fluid from fluid and gas into its inner space, portion (35) for jetting a mixed fluid comprising nano-bubbles of gas, and structural portion (5) which generates nanobubbles to generate nanobubbles from gas, between inlet part (11) and jet discharge part (35). Structural part (5) generating nanobubbles contains a plurality of flow paths (15, 28, 36) having different cross-sectional areas, through which mixed fluid from fluid and gas passes in axial direction of nozzle (1), generating nanobubbles.
EFFECT: invention provides high efficiency of nanobubbles generation.
