In exhaust gas treatment, micro nano bubble generators can be applied in the following areas:

1. Gas absorption: Micro nano bubble generators can dissolve harmful gas molecules in waste gas in water, forming tiny bubbles. These bubbles have a larger specific surface area, increasing the contact area between gas and water, thereby improving gas absorption efficiency.

2. Biological treatment: In the biological waste gas treatment system, the micro nano bubble generator waste gas treatment technology can provide sufficient oxygen for microorganisms, promote their growth and metabolic activities. This helps to improve the effectiveness of biological treatment, accelerate the decomposition and removal of organic matter in exhaust gas.

3. Catalytic oxidation: The small bubbles generated by the micro nano bubble generator can serve as a carrier for the catalyst, evenly dispersing the catalyst in the exhaust gas. This helps to improve the efficiency of catalytic oxidation reactions, promote the conversion and removal of harmful gases.

4. Aerosol removal: The exhaust gas may contain aerosol particles, such as dust, smoke, etc. The micro nano bubble generator can generate tiny bubbles, causing aerosol particles to collide with bubbles and adhere to their surfaces, thereby achieving aerosol removal.

5. Odor control: Micro nano bubble generators can be used to control the odor and foul odor in exhaust gas. By injecting bubbles into the exhaust gas treatment system, the reactive oxygen species in the bubbles can react with odor molecules, reducing or eliminating their odor.

It should be noted that the application of micro nano bubble generators in waste gas treatment needs to be selected and designed based on specific waste gas components, treatment processes, and requirements. Meanwhile, in order to ensure its effectiveness and safety, appropriate experiments and evaluations are also necessary.
