轴向流吸附塔流场数值模拟与进口分布器优化
Numerical Simulation and Optimization of Flow Field of Inlet Distributor of Axial Adsorption Tower
摘要
Abstract
For the flue gas distribution problems of the pressure swing adsorption tower in sugar mill, CFD (computational fluid dynamics) software was utilized for the flow field in numerical simulation, which focused on the flow field optimization of the inlet area(the area between the inlet pipe to the adsorbent).The flow field simulation of the original plate distributor shows that the velocity of the center is larger, resulting in uneven distribution of axial and radial velocity of the end section of the entrance region and a certain swirl.The process of plate distributor in different dip angles was compared,and it was found that the dip angle of baffle distributor had better gas distribution effect at 25° to 40°.The effect of gas distribution of 4 kinds of plate distributor was compared, which were the original distributor (Ⅰ),the distributor with the middle baffle without hole(Ⅱ), the distributor with middle small hole(Ⅲ) and the original distributor with baffle at middle(Ⅳ).It is found that the gas distribution effect of 2 and 3 is better than the original distributor, wherein the plate type effect is the best when the plate distributor is changed into small hole. Through optimization of the import area distributor for adsorption tower, the distribution of fluid is improved in the adsorption tower evenness.关键词
