摘要
建立吸附床的传热数学模型,对套管式吸附床的传热性能进行数值模拟,并对影响吸附床传热性能的因素进行分析。结果表明:吸附剂导热系数是影响吸附床传热性能的关键因素,减小床层厚度和缩小套管的尺寸也能够明显改善吸附床的传热性能。
The mathematical mode of double-pipe adsorption bed is established in order to simulate its heat transfer performance and analyze related influencing factors. The re- sults show that the adsorbent＇s coefficient of thermal conductivity is the key influencing factor to the heat transfer performance of adsorption bed. In addition, reducing the bed thickness or the tube size could also improve the heat transfer performance.
