To provide a rotary blade type bubble generator with a small required power, to which a broader scope of liquids can be applied, whose maintenance is easy, and in which bubble sizes can be broadly set in the system.
The rotary blade type bubble generator includes a gas inflow pipe 3 that gets a gas into the liquid to be scattered as gas bubbles in the liquid, a rotary blade 2 that has a hollow section 22, is communicated with the gas inflow pipe 3, and performs a circular movement in the liquid, a vacuum surface 21 that produces vacuum status on the surface of the rotary blade 2 with the circular movement of the rotary blade 2, a diffusion hole 23 that is formed from the hollow section 22 of the rotary blade 2 to the vacuum surface 21 and diffuses the gas into the liquid, and a rotary means 4 that allows the rotary blade 2 to be circularly moved so as to allow the pressure of the vacuum surface 21 to be the atmospheric pressure inside the hollow section 22 or less.
