Abstract:
1. A micro-sized bubble generator using a highly-dissolved solution based on a rotating unit, comprising: a rotating unit receiving a mixture of water and gas and discharging a solution while making the water and gas collide with each other and rotating the same; a dissolving tank storing the solution discharged from the rotating unit; and a nozzle unit receiving the solution and generating micro-sized bubbles in the water, wherein the rotating unit comprises: a rotating main body including a water/air inlet receiving the mixture of water and gas and a solution outlet discharging the solution; and a water/air rotation guide provided in the rotating main body, and inducing the mixture of the water and air having flowed into the rotating main body through the water/air inlet toward the outlet by rotating the mixture of the water and air to generate the solution, wherein the rotating main body is formed in the shape of a circular cylinder, the water/air inlet is formed along a tangent line direction of the rotating main body, and the solution outlet is formed in the center axis in the length direction of the rotating main body, and the water/air rotation guide comprises at least one water/air guiding wall provided in the rotating main body to allow the flow of water to the solution outlet from the water/air inlet, wherein the water/air guiding wall comprises a first wall/air guiding wall formed in the shape of a pipe, and a first end of the first water/air guiding wall is fixed to one side inner wall of the rotating main body where the solution outlet is formed while surrounding an area of the solution outlet, and a second end of the first water/air guiding wall is separately disposed from the other side inner wall disposed opposite to the one side inner wall of the rotating main body, wherein an inclined surface is formed in at least any one of the inner wall of the rotating main body and the first water/air guiding wall so that the inclined surface has a cross-section that is gradually decreased along a solution flow direction.
