Definition of the size of micro-nano bubbles
Usually we refer to the phenomenon of gases in liquids as bubbles. The formation phenomenon of bubbles can be encountered in many processes in nature. When gas is subjected to shear force in a liquid, bubbles of different sizes and shapes will be formed. In order from large to small, they can be divided into centimeter bubbles (CMB), millimeter bubbles (MMB), micron bubbles (MB), micro-nano bubbles (MNB), and nanobubbles (NB). Micro-nano bubbles refer to bubbles with a diameter ranging from a few microns to hundreds of nanometers when bubbles occur. These bubbles are between micro bubbles and nano bubbles and have physical and chemical properties that conventional bubbles do not have.
Application of micro-nano bubble generator
Application of micro-nano bubbles in water treatment
Micro-nano bubbles have excellent oxygenation ability and good air circulation. With floating effect and strong oxidation, micro-nano bubbles can be used to treat organic matter, nitrogen, phosphorus and toxic and harmful substances in water, thereby effectively improving water quality. Micro-nano bubbles are widely used in water oxygenation, ozonation enhancement, air flotation, and biological activity enhancement.
Application of micro-nano bubbles in planting industry
Micro-nano bubble technology is widely used in breeding, rice, soilless cultivation, promoting seed germination and enhancing water activity, oxygenation, disinfection and irrigation and other agricultural fields.
Application of micro-nano bubbles in medicine
The use of superoxide micro-nano bubbles can supply oxygen to the matrix while delivering drugs directly to the diseased site, thereby achieving direct treatment of the diseased site. treatment, reducing the number of surgeries and allowing the body to recover quickly.
Application of micro-nano bubbles in drag reduction of ship motion
Covering the surface of the ship hull with a layer of micro-nano bubbles can change the friction between the hull surface and water to the friction between gas and water Friction resistance, thereby reducing the ship's sailing resistance and increasing its sailing speed.
Application of Micro-Nano Bubbles in Precision Chemical Reactions
In fine chemical reactions, micro-nano bubbles mainly wrap or isolate reaction raw materials through micro bubbles, and then pass into micro-channels or micro-cavities The reactants separated by bubbles are brought into contact, and a chemical reaction occurs under the action of a catalyst or cavitation reaction. Controlling the size of the bubbles can control the number of raw materials participating in the reaction with high precision, thereby precisely controlling the process of the chemical reaction.
