Micro-Nano Bubble Generator
What’s Micro-Nano Bubble
The tiny bubbles in the liquid are called microbubbles when the diameter of the bubbles is less than 100um, and the bubbles with a diameter of less than 100nm are called nano bubbles. Micro-nano bubbles refer to bubbles with diameters ranging from a few microns to hundreds of nanometers when they occur. These bubbles are between micro-bubbles and nano-bubbles and have physical and chemical properties that conventional bubbles do not have.
What’s the micro-nano bubble generator
The micro-nano bubble generator is mainly composed of two parts: the generating equipment and the releasing
equipment, in which the supporting pipelines need to be connected, mainly including the air inlet pipeline, the water inlet pipeline, the water outlet pipeline, and the release equipment. When the gas enters the generating equipment through the intake pipeline, it is fully mixed with the raw water, and then processed by equipment stirring and mixing to generate micro-nano bubbles with a diameter of less than 50um, which are then released in the form of aeration
through the release equipment.
1 Micro-nano bubble characteristics
- Large specific surface area
- The total surface area of the bubbles is inversely proportional to the diameter of the individual bubbles when the total
volume is constant (V is constant). According to the formula, the specific surface area of a 10-
micron bubble is theoretically 100 times that of the latter under a certain volume compared with a 1-millimeter bubble. The contact area of air and water is increased by 100 times, and the speed of various reactions is also increased by 100 times.
2 Micro-nano bubble characteristics
Slow ascent
According to Skunks’ law, the rising speed of bubbles in water is proportional to the square of the diameter of the bubbles. The smaller the bubble diameter, the slower the rising speed of the bubbles. From the relationship between the rising speed of the bubbles and the diameter of the bubbles, it can be seen that the rising speed of the bubbles with a diameter of 1mm in water is 6m/min, while the rising speed of the bubbles with a diameter of 10um in water is 3mm/min, and the latter is 1/2000 of the former. . If the increase in specific surface area is considered, the dissolving ability of micro-nano bubbles is 200,000 times higher than that of ordinary air.
3 Micro-nano bubble characteristics
- Self-pressurized dissolution
- There is a gas-liquid interface around the bubbles in the water, and the existence of the gas-liquid interface makes the bubbles subject to the surface tension of the water. For bubbles with spherical interfaces, the surface tension can compress the gas inside the bubble, so that more of the gas inside the bubble dissolves into the water. According to the Young-Laplace equation, P=2/rP represents the value of the pressure rise, which represents the surface tension. r represents the bubble radius. The pressure of bubbles with a diameter of more than 0.1mm is very small and can
be ignored, while the tiny bubbles with a diameter of 10um will be
subjected to a pressure of 0.3 atmospheres. A bubble with a diameter of 1um is subjected to a pressure of up to 3 atmospheres. The dissolution of micro-nano bubbles in water is a process of gradually shrinking the bubbles. The rise of pressure will increase the dissolution rate of the gas. With the increase of the specific
surface area, the shrinking speed of the bubbles will become faster
and faster, and finally dissolve into the water. Theoretically, the pressure when the micro-nano bubbles are about to disappear is infinite.
4 Micro-nano bubble characteristics
- Surface charged
- The pure aqueous solution is composed of water molecules and a small amount of ionized H and OH. The gas-liquid interface formed by bubbles in water has the characteristics of easily accepting H and OH, and usually cations are easier to leave the gas-liquid interface than anions, and the interface is often banded. has a negative charge. Thealready charged surface generally tends to adsorb counter ions in the medium, especially high valence counter ions,thereby forming a stable electric double layer. The potential difference generated by the surface charge of micro-nanobubbles is often characterized by electric potential. The potential is an important factor determining the adsorption performance of the bubble interface. When the micro-nano bubbles shrink in water, the charged ions are apidly concentrated and enriched on the very narrow bubble interface, which is manifested as a significant increase in the potential, and a very high s potential value can be formed at the interface before the micro-nano bubbles burst.

characteristics
- Generate a lot of free radicals
- At the moment when the micro-nano bubbles burst, due to the dramatic change in the disappearance of the as-liquid interface, the high-concentration ions accumulated on the interface release the accumulated chemical energy at once,which can stimulate and generate a large number of hydroxyl radicals. Hydroxyl radicals have a super high redox potential, and the super strong oxidation produced by them can degrade pollutants such as phenol that are difficult to oxidize and decompose in water under normal conditions, and achieve the purification effect of water quality. • High gas dissolution rate • The micro-nano bubbles have the characteristics of slow rising speed and self-pressurized dissolution, which makes the micro-nano bubbles gradually shrink to nanoscale during the slow rising process, and finally reduce the annihilation fire.

- 01 Micro-nano bubble bath
- The basic principle of the nano milk bath machine is to use the molecular structure to collide with each other, and then use ultra-high pressure to rotate and cut, so that the oxygen molecules and microbubbles are close to the nanometer, resulting in negative air ions, magnetized water, and reducing the composition of chlorine in the water. Because of its closeness to nanometerization, the negative air ions and oxygen molecules can quickly penetrate into the skin pores, remove the aged stratum corneum, and clean the pores. The ultra-ultra-fine particle bubbles can create multiple negative air ions than waterfall baths and forest baths, turning them into high-efficiency energy active bath therapy tap water, which causes high-frequency ultrasonic waves to release huge undulating kinetic energy. To achieve detoxification, aging, anti-anxiety, calming effect, from the inside out, really make you comfortable. Nano milk bath effect relieves work stress.

The micro-nano-bubble hydrogen-rich water device adopts the cyclone countercurrent and multiphase eddy current gas-liquid shear technology to design the structure according to the hydromechanical calculation. The gas-liquid mixed fluid entering the countercurrent generator is subjected to a secondary ultra-high speed under the action of pressure. Rotate to generate micronano hydrogen-rich water, and form a negative pressure shaft in the middle of the countercurrent mixer. Using the suction of the negative pressure shaft, the hydrogen can be connected to the negative pressure shaft. When the super-high-speed rotating water and hydrogen are under appropriate pressure When ejected from the specially designed jet port, high-speed and strong shearing and high-frequency pressure fluctuations are generated between the gas-liquid contact interface to form micronano hydrogen-rich bubble water with artificial extreme conditions. The dissolution rate of hydrogen in water exceeds 95-99% %, under these conditions, a large amount of micron-nano gas-rich sparkling water is generated.
Application of Micro-Nano Bubbles
- Micro-nano bubble aerobic irrigation (soilless culture)
- In the production process of hydroponic plants, the amount of dissolved oxygen in water is an important factor affecting the growth and development speed of ecological agriculture. If the dissolved oxygen is sufficient, the growth will be fast. If the dissolved oxygen is low, the growth will not only be slow, but it will also be below the critical value of the dissolved oxygen in the plant. There will also be hypoxia and rotten roots, so in the future ecological agriculture technology, micro-nano bubble technology will be an indispensable supporting new technology.
Application of Micro-Nano Bubbles
- In facility horticulture and dry land drip irrigation, the traditional oxygenation method is relatively inefficient, and it is difficult to rapidly increase the dissolved oxygen value in the irrigation water. The use of the micro-nano bubble rapid generation device to aerate the irrigation water can quickly make the dissolved oxygen value reach Supersaturated state, the formation of micro-nano bubble water with dry irrigation. Micro-nano bubble water can not only provide sufficient oxygen, but also have special biophysiological
activities due to its unique electrification,
oxidation, and bactericidal properties, and promote the growth and development of plants.
Application of Micro-Nano Bubbles
- Micro-nano bubble oil-water separation
- The trajectory of the micro-nano bubbles in the water is not straight up, but a slow rise in lateral
motion. It takes 4 to 5 hours on average to rise 1
meter. The trajectory of the lateral movement and the long-term stay in the water allow the bubbles to capture oil droplets. Create plenty of time. Because the micro-nano bubbles are very small, they have the surface energy of the tiny particles of any object, and they have surface adsorption for other objects. Coupled with the electrification function of some bubbles, they can also adsorb gas objects. Therefore, oil can be adsorbed in oilcontaminated water. Droplets and other pollutants, make tiny oil droplets gradually aggregate into larger oil droplets and quickly rise to the water surface to complete the oil-water separation of oil-contaminated water.
