Definitions
- the present invention relates to a nanobubble generation system using friction that induces miniaturization of bubbles and generates nanobubbles by applying a frictional force to bubbles contained in a gas-liquid mixed fluid.
- microbubbles are divided into microbubbles having a diameter of 50 ⁇ m or less and nanobubbles having a diameter of several hundred nm or less according to their size.
- Microbubbles are very fine bubbles of less than 50 ⁇ m, rise to the surface at a very slow rate of 0.1cm/sec, disappear within 2-3 minutes after being created, and have a pale milky color in the water.
- Nanobubbles are very small microbubbles of a few hundred nm or less in which microbubbles are deepened and fined. They have various characteristics different from ordinary bubbles and microbubbles, and are transparent, so even if they are floating in water, it is impossible to identify them with the naked eye.
- nanobubbles When these nanobubbles disappear, they generate various energy and are used for various aquaculture and hydroponic cultivation in fishery and agricultural fields.
- precision diagnosis, physical therapy, and wastewater in the living field high-purity purification/refining treatment of waste oil, sterilization, It is used in various fields throughout the industry such as disinfection, deodorization, and cleaning.
- guide blades are arranged at the inlet and outlet of the mixing unit (chamber) to guide the flow of fluid
- a rotor and a stator having a meshing structure around the motor shaft are continuously stacked, and the teeth formed in correspondence with the stator and the rotor by the relative rotation of the rotor to the stator are repeatedly hit by the fluid. It can be summarized as a structure in which a shear force is applied to the air bubbles by increasing turbulence and cavitation pressure to the fluid to generate microbubbles.
- the prior art 1 having such a configuration has a structure in which most of the bubbles are only generated as microbubbles, so that the quality of micronization of the generated bubbles is low, the dissipation time is short, and the flow is made in a structure in which the fluid is forcibly bypassed in a zigzag form through the meshing gap.
- productivity is not followed because the flow drag coefficient is large, so that the power consumption is large, and the processing flow rate is insufficient.
- JP 2009-142442 hereinafter referred to as “prior art 2” as a conventional technique of a method different from that of the prior art 1 has a plurality of arrays of rotating disks having a front end formed on a rotating shaft installed in the chamber. It is a structure that becomes.
- the prior art 2 has the advantage of increasing the discharge amount of fluid and significantly reducing power and operating costs by freeing the flow by allowing the rotating disk to rotate independently, not by relative rotation, but it is also composed only of the rotating disk, which has the application of shear force as the main function. As a result, only microbubbles are generated, and there is a disadvantage in that the bubble generation efficiency is inferior.
- the microbubble generation technology to date has remained in the microbubble generation, and the nanobubble is not practically used in the industrial field, although its utility is excellent.
- the present invention is to solve the above problems
- Another object of the present invention is to preemptively refine the air bubbles contained in the gas-liquid mixed fluid in a microbubble step, and then generate nanobubbles using the principle of microbubbles according to the friction, thereby preventing friction to efficiently generate nanobubbles.
