Study on the flow field analysis and oil–water separation performance of micro-cyclonic floatation tube
The swirling air flotation technology has been extensively utilized in the field of oil-bearing wastewater treatment. However, methods for visualizing internal flow characteristics and optimizing equipment performance need further exploration. In this study, we employed computational fluid dynamics (CFD) method along with Euler-Euler model and PBM model to analyze the distribution characteristics of the flow field within a micro-cyclonic floatation tube. The Lagrange method was utilized to analyze the trajectory of oil droplets, providing information on separation efficiency for different oil droplet sizes. Furthermore, we designed and constructed a dedicated test device for evaluating the oil removal performance. Experimental investigations were conducted to examine the influence of dissolved gas pressure and gas inlet on pressurized dissolved gas effect, and the relationship between bubble quality and oil removal performance was demonstrated. Finally, based on response surface optimization design method, we determined optimal operating conditions for swirl flotation tubes.
期刊介绍：
The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide.
The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them.
Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
