(57) This invention relates to a method for mixing a gas with a liquid or a liquid with
a liquid, and a device designed to implement the said method.
The said device comprises a propeller (1) which contains a channel that places the
upper surface of the blades (4) in communication with the environment containing a
gas or liquid to be mixed with a liquid. The said device draws the gas, such as air,
from the external environment (or a liquid) using the negative pressure generated
on the upper surface of the propeller blades immersed in the liquid, such as water,
when the propeller is rotated, the said negative pressure being sufficient to suck
in the said air. The air thus aspirated will mix effectively with the liquid mass
due to the effect of the vortex caused by the rotating propeller, which breaks up
the air into a myriad of bubbles, thus greatly increasing the exchange surface.
