Nanobubble generation system using friction

A nanobubble generation system using friction, the nanobubble generation system comprising:

• a chamber including an inlet, an outlet, and an internal space configured to atomize bubbles included in a gas-liquid mixed fluid, the chamber being provided with a driving shaft;
• one or more strikers each including a plurality of protrusions provided on a body thereof to simultaneously apply impact to the gas-liquid mixed fluid that flows into the chamber and swirl the fluid in order to cause the gas-liquid mixed fluid to rub against an inner wall of the chamber, the strikers being provided on the driving shaft;
• a plurality of friction elements provided on the driving shaft in order to apply frictional force to the gas-liquid mixed fluid;
• and
• a driving mechanism including the driving shaft and configured to rotate the strikers and the friction elements,
• wherein the plurality of friction elements are arranged on the driving shaft to be spaced apart from each other at a predetermined interval,
• the peripheral surfaces of the bodies of the friction elements directly face the inner wall of the chamber with a predetermined distance therebetween, and
• one or more small-diameter friction elements and one or more large-diameter friction elements having a relatively large radius compared to the small-diameter friction elements are arranged to be spaced apart from each other at a predetermined interval.

A nanobubble generation system using friction, the nanobubble generation system comprising:

• one or more micro-level atomization apparatuses configured to apply an impact and a shear force to a gas-liquid fluid to atomize bubbles to a micro-level;
• and
• a nanobubble generation apparatus configured to apply a frictional force to the gas-liquid mixed fluid passing through the one or more micro-level atomization apparatuses to atomize the bubbles into nanobubbles,
• wherein the nanobubble generation apparatus includes:
• a first chamber includes an inlet and an outlet for the fluid and an inner wall that defines a space configured to accommodate the gas-liquid mixed fluid and apply a frictional force to the fluid;
• one or more friction elements provided in the first chamber to be rotatable by using a driving shaft and configured to function as a friction mechanism for the fluid that generate a centrifugal force to push the fluid to the inner wall;
• and
• a first driving mechanism including the driving shaft in order to rotate the friction elements, and
• wherein the micro-level atomization apparatus of the one or more micro-level atomization apparatuses includes:
• a second chamber including an inlet, an outlet, and an internal space configured to atomize the bubbles included in the gas-liquid mixed fluid, the second chamber being provided with a driving shaft;
• one or more strikers or impellers provided on the driving shaft and each including a plurality of protrusions configured to apply an impact to the fluid, and wherein the at least one of said one or more strikers is provided on the driving shaft of the nanobubble generation system together with the one or more friction elements;
• and
• a second driving mechanism including the driving shaft and configured to drive the strikers or the impellers.
