摘　　要：为了提高氙核查系统中分子筛除杂柱的除杂性能,采用静态吸附和动态吸附两种方法对系统中分子筛除杂柱的性能进行了研究。研究结果表明,除杂柱的长度、直径,分子筛的质量,空气中水的含量,吸附过程的温升效应以及分子筛柱的活化好坏都对除杂柱的除杂性能有影响。根据研究结果并结合经验对氙核查系统中的分子筛除杂柱进行了优化设计。In order to improve the performance of zeolite scavenge column, its ability of removal of humidity and carbon dioxide was studied by both static and dynamic approaches. The experimental results show that various factors, including the column length and diame- ter, the mass of zeolite, the content of water in air, the temperature rise during adsorption, and the activation effectiveness all effect the performance of zeolite column in scavenging humanity and carbon dioxide. Based on these results and previous experience, an optimized design of the zeolite column is made for use in xenon monitoring system.
