摘要/Abstract

摘要： 为提高空分用吸附器吸附效率,通常在内分布流道布置一锥体使内外分布流道沿轴向压降梯度相等以保证空气在吸附剂中流场均匀。通过对立式径向Z型吸附器内的压降分析,推导出一个可表征当空气在吸附剂中均匀分配时吸附器各参数应满足的量纲1微分控制方程。同时对一个实验径向吸附器进行设计,利用该量纲1微分控制方程获得了锥体截面半径随轴向高度的变化规律,为该类径向吸附器的设计提供了理论依据。

Abstract: In order to improve adsorption efficiency for air separation,a cone is commonly designed in internal flow passage to keep equal pressure drop gradient along axial direction of internal and external flow passages to ensure that air is distributed uniformly in adsorbent.This paper concludes a dimensionless differential equation that adsorption bed parameters must meet when air is uniformly distributed in adsorbent by pressure drop analysis of vertical radial Π type flow adsorption bed.An experimental radial adsorption bed is also designed in this paper.The variation law of cone section radius along axial height is obtained by solving this dimensionless differential equation,which provides theoretical support for designing this kind of radial flow adsorption bed.

Key words: vertical radial, adsorption bed, uniform distribution
