Abstract

The invention relates to an apparatus and a method for preparing micro bubbles from antibubbles. In one embodiment, the apparatus comprises an antibubble generator, an antibubble fragmentation chamber and a large bubble filter; the antibubble generator is used for generating antibubbles in fluid; the antibubble fragmentation chamber is used for coupling one or a plurality of forces and forming an outside force field; gas films of antibubbles are fragmented under effect of the outside force field for forming micro bubbles. micro bubbles are precipitated under the filtering effect of the overflow interface of the large bubble filter. In the embodiment of the invention, micro bubbles are formed by fragmentation of antibubbles, thereby realizing stable large-scale preparation of micro bubbles of micron order with high efficiency by screening and circulation of fluids.

Description

technical field [0001] The invention relates to the field of microbubble preparation, in particular to a device and method for preparing microbubbles by using anti-bubbles. Background technique [0002] Microbubbles have the characteristics of small bubble size, large specific surface area, high adsorption efficiency, and slow rising speed in water. Introducing micro-nano bubbles in water can effectively separate solid impurities in water, quickly increase the oxygen concentration of water, kill harmful bacteria in water, and reduce the friction coefficient of solid-liquid interface. In the fields of drag reduction and other fields, nano-bubbles have higher efficiency than macro-bubbles, and their application prospects are broader. [0003] There are many methods for the preparation of microbubbles, such as the bubble breaking method that uses the shear force or pressure gradient of the fluid to break the bubbles into smaller microbubbles; the ultrasonic method that uses ul...
