转盘反应器亲疏水相间表面结构微观混合性能
Microscopic mixing performance of hydrophilic-hydrophobic phase interfaces in rotating disk reactors
摘要
Abstract
A rotating disk reactor with different hydrophilic-hydrophobic phase interface structures was designed and prepared.Based on the parallel competitive reaction system of iodide-iodate,the effects of different phase interface structures,rotation speed and flow rates on microscopic mixing performance were investigated.The influence of hydrophilic-hydrophobic critical occurrences on mixing was also analyzed.The results show that increasing the rotation speed effectively reduces the segregation index,and higher speeds lead to better microscopic mixing effects.With the increase in reactant flow rates,optimal flow rate points for microscopic mixing performance are observed.Increasing the number of hydrophilic-hydrophobic phase interfaces enhances the number of occurrences of liquid passing through the critical region,effectively strengthening the microscopic mixing performance.A predictive correlation equation for the segregation index XS of hydrophilic-hydrophobic phase interface structures was established.This study contributes to a deeper understanding of the impact mechanism of reactor surface non-uniform wettability on microscopic mixing performance,providing a theoretical and applied foundation for the design and optimization of reactor structures.关键词
