Title:
FINE BUBBLE GENERATING UNIT
Document Type and Number:
WIPO Patent Application WO/2008/007631
Kind Code:
A1
Abstract:
[PROBLEMS] A fine bubble generating unit capable of constantly generating
fine bubbles using a comparatively simple structure and at a low cost. [MEANS
FOR SOLVING PROBLEMS] The fine bubble generating unit (1) comprises a motor
(2), a rotary shaft (4) rotated by the motor (2), a rotary disc (5) attached to the
tip end of the rotary shaft (4), a cylinder (6) surrounding the outer periphery
of the rotary shaft (4) with a space between them and having a gas introducing port
(10a), a flange (9) attached to the tip end of the cylinder (6) and surrounding
the outer peripheral edge of the disc (5) with a gap between them, and a tubular
mesh member (11) provided to extend forward beyond the periphery of the flange
(9). The disc (5) is rotated in liquid to allow liquid at the lower end of the disc
(5) to flow in an outward direction by centrifugal force, this liquid flow is used
to suck out gas in the cylinder (6) through the gap between the disc (5) and the flange
(9) and mix it with the liquid to form a bubble-mixed liquid flow, and this liquid
flow is allowed to impinge against the mesh member (11) to atomize bubbles while
being passed through the mesh member.
