Abstract

Abstract The initial liquid film is the basis of material evaporation during distillation, so it is of great significance to study the distribution of the initial liquid film of distributor in the process of scraping film molecular distillation. In this paper, CFD is used to study the distribution of distributor liquid film, and the mathematical model of the triangular tooth distributor and its peripheral cylinder is established, and the effects of the triangular tooth distributor’s speed, feed rate, and feed position on initial liquid film uniformity are investigated. And the reliability of the numerical simulation model is verified by experiments. In this paper, a new feed structure that includes an intermediate feed device and inclined tooth distributor is proposed and researched by numerical simulation. And compared with the previous structure, the liquid film distribution is more uniform. This has important guiding significance to the optimization of equipment in production.
