基于CFD的立式吸附塔内气体分布器的结构优化
Structural Optimization of a Gas Distributor of Vertical Adsorption Tower Based on CFD
摘要
Abstract
The vertical adsorption tower is crucial for carbon dioxide removal from flue gas,but its complex and variable adsorption process poses challenges for optimal production.Achieving uniform gas distribution is essential,prompting the evaluation of various gas distributors via computational fluid dynamics(CFD).Four types were compared:no distributor,conical,truncated cone,and a combination of sieve plate with baffle.Results were assessed based on velocity vector smoothness and curve uniformity.A single sieve plate resulted in non-uniform airflow concentrated at the tower center.Types Ⅰ and Ⅱ improved flow but with uneven distribution.Type Ⅲ,featuring a sieve plate and baffle,significantly enhanced uniformity.Optimal parameters identified were a baffle diameter(d)of 100 mm and a distance(h)of 150 mm from sieve plate to air inlet.This configuration achieved the most uniform airflow distribution,demonstrating superior effectiveness in carbon dioxide adsorption processes.关键词
