Claim 13:
14. The nano bubble generating system of claim 12, wherein
the slant of cylindrical surface of each of the rotating blades is comprised of a first slanted part in which its surface is slanted against rotation direction of the rotating blade so that it is higher in rotation direction and lower on an opposite side of rotation direction, and
the slant of cylindrical surface of each of the fixed blades is comprised of a second slanted part in which its surface is slanted against the slant direction of the cylindrical surface of each of the rotating blades so that it is relatively lower on the opposite side of the surface of the first slanted part and higher on its other side,
wherein a vortex accelerating part is formed such that the rotating blade, the fixed blade, and the blade sides of both blades are slanted against a reference radius line.
