| 英文摘要 | The tubular mixer-settler has a broad application prospect in industrial production. A tubular mixer settler was simulated by using computational fluid dynamics (CFD). The effects of dispersed phase droplet size (d32 = 100-500 渭m), oil-water ratio (O:A=1:1-1:5), inlet baffle position on the mixing and settle performance of tubular mixer-settler were systematically investigated. The simulation results were compared with those of traditional square mixer-settler. The results show that the flow field distribution in the tubular mixer chamber is better than that in the square mixer chamber, in which the flow dead zone is not easy to generate. In the tubular mixer chamber, a lower pressure zone is formed above and below the impeller, and the turbulent kinetic energy of the fluid is higher. The mixing performance can be improved by reducing d32 of dispersed phase and oil-water ratio of feed. In the tubular settler, increasing the dispersed phase d32 and reducing the feed oil-water ratio can improve the clarification performance, and the inlet baffle can effectively improve the clarification performance. 漏 2021, Editorial Board of CIESC Journal.
