General water-in flow velocity V
1selected scope be 4-10 meter per seconds, therefore water outlet flow velocity V
2speedup scope be 256-640 meter per seconds.Bubble in gas-liquid mixed stream is compressed under High Pressure, once from spout ejection, will be broken rapidly, and form the ultra micro small bubbles that speed is very high.
High rate activated oxygen microbubble sprays and enters by generation three kinds change after in water, and the first is bubbles burst, and active oxygen is dissolved in the water with molecular state becomes dissolved oxygen; The second is that bubble keeps ortho states in water laterally, move upward downwards, just can rise to the water surface, the effect playing oxidative degradation in this process and purify waste water after 4-5 hours; The third becomes a comparatively large bubble for bubble merges, along with bubble constantly merges growth, bubble the water surface by rising.In a first scenario, active oxygen microbubble enters after in water, walls is caused to have higher tension force because bubble internal pressure is higher, collide or other conditions cause bubbles burst, the tension force effect of walls is by energy huge for release, and this energy can impel active oxygen species to be dissolved in water, pollutent can be destroyed to be connected with the covalent linkage of water simultaneously, the chemical bond that also can destroy pollutent inside connects, and active oxygen plays a role simultaneously, completes oxidative degradation pollutent and purification of water quality.In a third case, after active oxygen microbubble enters in water, namely bubble merges when becoming air pocket, walls surface tension is caused to decline because bubble merges, the bubble merged is by bubble incorporation energy larger for release, this combination can cause the covalent bonds between the pollutent of bubble periphery and water to be broken, and makes the active oxygen in bubble produce oxidative degradation and the solvency action of active oxygen species in water to pollutent.
The high energy oxygen bubbles that this microbubble generator produces or molecular grouping are sprayed onto in air in the mode that gas-liquid is sprayed, because active oxygen bubble has very high energy, the various pollutents in air can be caught, and to pollutant oxidation degraded, reach the object purified air.
