Micro-nano bubble oxidation tower
The micro/nano oxidation tower uses nano fine bubble water to wash and purify the waste gas. The nano bubble water is sprayed onto the filler from the reaction zone inside the tower through a bubble distributor and flows down the surface of the filler. The gas is sent from the bottom of the tower, and after passing through the gas distribution device, it continuously flows through the gap of the packing layer in a countercurrent manner with the liquid. On the surface of the packing layer, the gas-liquid two phases are in close contact for mass transfer. Nanobubbles react with the exhaust gas in the tower and then flow back to the bottom of the tower for recycling. The packing layer in the spray tower serves as a mass transfer device for the gas-liquid two phase contact components. The bottom of the tower is equipped with a packing support plate on which the packing is placed in a uniform manner. Nanoscale bubbles make the atomic clusters of water molecules smaller, and oxygen in nanobubbles easily dissolve into the gaps of the atomic clusters. At the same time, oxygen molecules break the water interface, making it easier for ultrafine bubbles to dissolve into water; The water molecules always undergo a "Brownian motion", constantly carrying out irregular collisions. At the same time, superoxide micro and nano bubbles also settle and break; When a large number of negative oxygen nanobubbles are dissolved and ruptured in water, an ultrasonic wave of about 400 kilometers per hour is generated during transient high-temperature cracking, and a large number of oxygen negative ions are generated. As a result, the gas continuously rises into the upper and lower reaction zones. In the reaction zone, the nanobubbles will continuously crush and crack, releasing a certain amount of instantaneous energy while cracking organic molecules.
Application of Ultrafine Nanobubble Technology in Waste Gas Treatment
Superoxide ion nanobubble catalytic oxidation technology uses a large number of active particles in the nanobubble to promote the reaction with pollution source molecules, using both free radicals and active free oxygen in the nanobubble to produce a mixture including negative ions, hydroxyl groups, atoms, and free radicals. Although the electron temperature is very high during the process, the temperature of heavy particles is very low, and the entire system presents a normal temperature state. Superoxide ion nanobubble technology is used to degrade pollutants by utilizing these high-energy electrons, free radicals, and other active particles to interact with pollutants in the exhaust gas, causing the decomposition of pollutant molecules in a very short time and subsequent various reactions to achieve the goal of degrading pollutants. Due to its efficient decomposition of pollutant molecules and low energy consumption for treatment, it opens up a new idea for the treatment of industrial waste gas.
After being stimulated by the physics of the environment (compression and expansion generated by the flow process of water, vortex flow, etc.), superoxide micro/nano bubbles will generate an ultra-high pressure of about 10 atmospheres and a limit reaction field of 4400 ℃ between molecules due to instantaneous (about 10-9 power seconds) adiabatic compression. The micro electricity of superoxide and active hydrogen oxygen, which are unique to the ionization phenomenon, can generate a large number of hydroxyl ions from water molecules in the air. The hydroxyl ions and the resulting hydroxyl radicals have a strong decomposition ability, resulting in a large number of smaller diameter microbubbles generated by the crushing effect, and exhibit characteristics such as ultrasound, electrification, retention, self pressurization, diffusion, and strong oxidation, Decomposition and elimination of organic compounds (VOCs) (chemical reactions), destruction and separation of the components of pollutants and suspension of the water surface, promote the conversion of some organic compounds (VOCs) into carbon dioxide and water, and the other part is mineralized to form granular sediment into water, with its characteristics of non combustion, non dissolution, and no toxicity. The removal rate of non methane total hydrocarbons, formaldehyde, benzene series, hydrogen sulfide, odor, and other organic substances (VOCs) is high.
