Abstract:
In a fine bubble generating apparatus, a first configuration body (1) and a second
configuration body (2) are permitted to relatively rotate in an air tight status.
The first configuration body (1) is mainly provided with a liquid introducing
path (3) and a gas introducing path (4) arranged at the center portion of the liquid
introducing path. The second configuration body (2) is mainly provided with
a spiral liquid introducing path (5) for introducing a liquid close to an exit
of the gas introducing path (4) while changing the liquid from the liquid introducing
path (3) into a spiral flow; and a gas-liquid mixture lead out port (6) for discharging
a gas-liquid mixture composed of the liquid in the spiral flow and the gas introduced
from the gas introducing path (4). The fine bubble generating apparatus can
freely change the introducing directions of the gas and the liquid even after
the apparatus is attached to a fixed section.
