AI Technical Summary
Existing technologies struggle to obtain nanobubble systems with high quantity concentration and concentrated particle size distribution under stable, efficient, and low-energy-consumption engineering conditions. Traditional methods suffer from high energy consumption, severe mechanical wear, poor bubble stability, and easy clogging of microporous structures.
A multi-stage synergistic processing system, including a first Venturi tube, a stirring vessel, a second Venturi tube, and a nanoporous membrane assembly, is employed to form a stable nanobubble system through gas-liquid mixing, eddy current suppression of agglomeration, interfacial energy loading, and size control.
It achieves low-energy consumption and high-reliability generation of nanobubbles with concentrated particle size distribution, high concentration and stability, solving the problems of concentrated energy input and insufficient bubble stability in traditional methods, and is applicable to water treatment, mineral flotation and oil and gas extraction.
