Study on Separation Efficiency of Dehydration Equipment with Corrugated Plates

Abstract

The complex problem on two-phase flow field in the dehydration equipment with corrugated plates is presented in the paper. The influence factors on dehydration effect were found by the numerical analysis on the gas-liquid two-phase flow field and droplets’ mechanical behavior in the dehydration equipment with corrugated plates while changing the structure parameters and operating conditions. Experiment on the separation efficiency and limit gas speed of dehydration equipment was carried out by changing the plate spacing, droplets diameter and spraying water flow. The results show that the dehydration equipment has the highest dehydration efficiency and minimum resistance loss when the distance between the plate is 15 mm, the droplets’ average diameter is 160 μm, and the spraying water flow is 0.89 m3/h. While the limit gas speed is affected by the plate spacing, droplets diameter and spraying water flow. The optimal limit gas speed is 3.7 m/s considering the correlative factors of dehydration efficiency and resistance loss comprehensively. The numerical simulation results agree well with the experimental results. It provides a guide for the industrial design of the dehydration equipment with corrugated plates.
