This paper combines theory with experiment to systematically analyze the mechanism of bubble generation by dissolved air method and how to generate miniaturized and large-scale bubbles. It also uses computer software to simulate and analyze the velocity field and pressure field of the fluid. Finally, it explores the effects of dissolved air tank pressure, releaser placement angle, and bubble rise height on the size and number of generated bubbles..Wuxi Yosun Environmental Protection Equipment Co.,Ltd
The two most abundant gases in the air are N2 and O2, both non-polar gases. Such non-polar molecules with very low solubility must exist in the gaps between water molecules, so gap filling is a way for air to dissolve in water. In addition, we know that as the temperature increases, the amount of gas dissolved in water decreases, so it is also believed that there is a chemical reaction between water molecules and gas molecules called hydration.
The pressure in the gas-dissolving tank directly affects the amount of dissolved gas. The greater the pressure value, the greater the theoretical value of the dissolved gas. Although increasing the pressure in the gas dissolving tank can increase the amount of dissolved gas, it will also increase the manufacturing difficulty and cost of the gas dissolving tank, pipeline, and releaser, increase energy consumption, and reduce economic benefits..Wuxi Yosun Environmental Protection Equipment Co.,Ltd
