摘要：The plate separator is a physical separation device widely used in the pre-separation of oil-water emulsions. The dynamic behavior of oil droplets impacting plate surface is crucial for the understanding of the enhanced separation mechanism and the design of the plate bed. In this study, a high-speed camera was employed to capture the process of oil droplet impact on the plate surface. The effects of droplet impact parameter and the tilt angle of the plate on the droplet dynamic behavior were investigated. The results show that the tilt angle of plate affects the residence time and rising trajectory of oil droplets, and an angle of 30 degrees is the better tilt angle. Furthermore, a vertical corrugated plate separator was designed for macroscopic separation experiments based on the study of droplet impact behaviors. The research finds that under low flow rate conditions, increasing the bed height significantly improves the oil removal efficiency of the separator. The corrugated plate separator exhibits better separation performance with emulsions containing higher oil concentration and larger droplet sizes. This research contributes to a microscale understanding of oil droplet impact dynamics in plate separators and provides guidance for the optimization and application of corrugated plate beds.
