Description

Technical Field

[0001] The invention relates to the field of micro-nano bubbles, in particular to a bubble generator prepared by micro-nano bubbles and micro-nano emulsion. Background Art

[0002] Nowadays, as countries pay more attention to environmental protection, food safety, medical health and other issues, and people pursue high-quality life, the application market of micro-nano bubble technology continues to expand, and the global market demand for micro-nano bubble generators continues to grow. According to relevant reports, the global micro-nano bubble market size will be about 0.4 trillion yuan in 2023. It can disinfect, preserve and diagnose food and items.

[0003] Specifically, the micro-nano bubble generator can prepare micro-nano bubbles and micro-nano emulsions. Nanobubbles have many remarkable properties. In the field of cleaning, the surface of micro-nano bubbles carries a strong negative charge, which enables them to maintain a high degree of stability in liquids and actively participate in and influence various physical, biological and chemical interaction processes. The size of nanobubbles is extremely small, usually less than 200 nanometers in diameter, which is about 2,500 times smaller than a single salt particle. This small size and the characteristics of neutral buoyancy enable them to suspend in liquids for a long time without quickly rising to the surface to escape gas, thereby ensuring that the huge total bubble surface area is fully in contact with the liquid and achieving ultra-efficient gas transmission. When nanobubbles are subjected to specific stimuli, unstable collapse occurs, thereby releasing hydroxyl radicals with strong oxidizing ability. These hydroxyl radicals can effectively degrade pollutants in water, providing a new way to clean and purify coolants. It has high cleaning performance.

[0004] In the field of mechanical processing, they can significantly improve cooling efficiency, and with their efficient gas transmission capabilities, they can more quickly absorb and remove the heat generated during the processing. At the same time, the small size of nanobubbles enables them to fill microscopic gaps more effectively, further optimizing the lubrication effect and reducing friction and wear. In addition, the hydroxyl radicals released by nanobubbles may also clean and prevent rust on the metal surface, enhancing the anti-rust and anti-corrosion properties of the coolant.

[0005] In the prior art, micro-nano bubble generators usually use cyclonic liquid flow generation, but they are usually difficult to clean internally, difficult to disassemble and maintain, difficult to control the outflow rate of micro-nano bubbles, and the uneven mixing of gas and liquid can easily lead to poor accuracy and effect of micro-nano bubble generation.
