晃动对规整填料吸收塔压降影响
Effect of shaking on pressure drop of structured packing absorption column
摘要
Abstract
An experimental study on the pressure drop in a column of inner diameter 600 mm, packed with Mellapak350Y metal corrugated plate structured packing,is carried out. The column is fixed on a swaying platform,which can achieve six degrees of freedom swaying. We study the influence of the packing pressure drop in the stationary state and shaking state with different gas velocities and different spray densities. The 2D and 3D CFD models based on the Mellapak350Y packing are es-tablished,to study the pressure distribution of the packing column and flow path of the packing under the conditions of sha-king.In the modeling process,we add the UDF program to achieve the shaking condition of the model. The results show that the shaking has no significant effect on the overall pressure drop of the packing, but the larger pitching or pitching-rolling coupling sloshing will increase the pressure drop to a certain extent when the gas velocity is large. At the same time,the strip distribution of the pressure drop of the packing will be changed in the axial direction,and even demonstrate the form of block or regional distribution.关键词
