The active oxygen components in superoxide micro nano bubbles have active chemical properties. When they rupture, they instantly generate energy and a large amount of oxygen ions, forming highly oxidizing hydroxyl radicals that can quickly react with harmful substances such as ammonia, hydrogen sulfide, thiols, volatile organic compounds, etc. in exhaust gas, converting them into harmless substances. In addition, micro nano bubbles have extremely small diameters, large specific surface areas, slow rising speeds, and long residence times in water. They can significantly increase the contact area between gas and liquid, improve mass transfer efficiency, and allow reactive oxygen species to more fully contact and react with pollutants in exhaust gas.
The Shanghai Zhongjing ultra-strong acid and alkali-resistant micro-nano bubble generator, with its outstanding anti-corrosion performance and stable micro-nano bubble generation capability, focuses on extreme corrosive environments while extending to multiple fields. Specific application scenarios can be categorized as follows, covering key areas such as industry, environmental protection, and healthcare
Shanghai Zhongjing Micro Nano Aeration Machine supports small-scale and high-precision aeration volume adjustment, meeting the aeration intensity requirements of different water samples and avoiding the problem of difficult control of aeration volume in traditional equipment. Stable and consistent bubble parameters: capable of generating uniformly sized micro nano bubbles with micrometer level accuracy, ensuring consistent key parameters such as bubble specific surface area and dissolved oxygen rate in each experiment, and guaranteeing the accuracy and comparability of experimental data. Efficient and energy-saving: Compared with traditional aeration technology, this technology can more effectively dissolve gas in liquid, improve gas utilization efficiency, and thus reduce energy consumption.
After the gas and liquid are fully fused in the mixing device, the strong shear force generated by the high-speed rotary cutting device will gradually break the bubbles. By utilizing the vortex pressure drop effect in fluid mechanics, gas is formed in a supersaturated state in liquid, and then uniform gas release is achieved through pressure fluctuations, breaking bubbles to the nanoscale of 10-100nm.
Shanghai Zhongjing Experimental Ozone Generator, with years of research and development experience, provides "accurate, stable, and flexible" oxidation solutions for global research teams, making every experiment closer to truth.
In the field of water treatment experiments, precision and efficiency are the key keys to unlocking scientific breakthroughs. The ozone micro nano bubble generator, meticulously crafted by Shanghai Zhongjing Environmental Protection Technology Co., Ltd., has become a powerful assistant for many researchers to explore the mysteries of water treatment with its cutting-edge technology and excellent performance, providing innovative and reliable solutions for various complex water treatment experiments.
Shanghai Zhongjing specializes in micro nano bubble generators, superoxide micro nano bubble generators, ozone micro nano bubble generators, oxygen rich micro nano bubble generators, and hydrogen micro nano bubble generators. Using multiphase fluid vortex cutting technology, gases (such as air, oxygen, ozone, nitrogen, hydrogen, etc.) are dissolved in liquid through a special device, and then the bubbles in the mixture are chopped up using high-speed vortex cutting to form micro nano bubbles with particle sizes ranging from 10-100nm.
Micro nano bubbles will gradually contract and eventually rupture during their ascent due to the pressure difference between the inside and outside. At the moment of rupture, the inside of the bubble generates high temperature (up to thousands of degrees Celsius) due to adiabatic compression, which promotes the decomposition of water molecules into hydroxyl radicals (· OH) with strong oxidizing properties. Hydroxyl radicals are highly efficient oxidants that can rapidly oxidize and decompose organic pollutants (such as VOCs, odorous substances, etc.) in exhaust gases.
This paper introduces conventional methods for generating micro-nano bubbles and systematically reviews the current research status and applications of this technology in environmental protection fields such as sewage purification, soil remediation, and waste gas treatment. It points out that the bubbles generated by micro-nano aeration technology have significant advantages such as long residence time, high mass transfer efficiency, high interfacial potential, and large specific surface area, which are of great significance for promoting technological development in the environmental protection industry and mitigating environmental pollution.
Micro nano bubbles can quickly and effectively increase the dissolved oxygen content of aquaculture water, providing sufficient oxygen for aquatic animals to meet their growth and metabolic needs, and improving the survival rate and growth rate of aquaculture organisms. Especially for high-density aquaculture environments, their oxygenation effect is more significant, which can effectively avoid phenomena such as floating heads and death of aquatic animals due to hypoxia
