摘要：

According to the characteristics of lithium electrolytic extraction and the fluid flow in the electrolyzer, the effects of the inlet position, fluid flow rate and fluid viscosity on the flow field in the electrolyzer were studied, respectively. Through the comparison of hydraulic experiments and numerical simulation, the applicability of the mathematical model was verified. The results show that the standard k-ε turbulence model can accurately describe the flow state of the fluid in the electrolyzer. Considering the larger viscosity of the salt lake brine, the inlet should be posited in the middle of the water inlet position, and the fluid flow should be increased as much as possible under the premise of without damaging the coated electrode to strengthen the mass transfer. © 2019, Science Press.
