Analysis of flow field characteristics of the three-dimensional staggered rotor and its influence on structural parameters in the wiped film molecular distillation
Abstract
The implementation of a scraping rotor has enhanced the distribution of the liquid film in wiped film molecular distillation while also preventing groove flow and drywall phenomena. To investigate the structure of the rotor and its surrounding cylinder, a three-dimensional mathematical model of the interleaved rotor has been established using computational fluid dynamics (CFD), and the accuracy of the simulation model has been validated through experiments. Additionally, a three-dimensional staggered cylindrical rotor has been developed and used to explore the impact of different structural parameters on the distribution of the head wave and liquid film thickness. These findings have provided a theoretical basis for the creation of new rotor devices and furnished valuable empirical parameters for practical engineering applications. Furthermore, this research has been instrumental in elevating the efficiency and effectiveness of wiped film molecular distillation, and at the same time, it provides important support for improving the structure of the scraping film molecular distillation equipment in the industry.
