摘要
通过热动力学计算,认识了脱附过程当中储罐内温度剖面分布的典型特征:储罐轴心处的温度下降幅度最大。分析了脱附过程当中储罐壁的热交换、吸附剂的导热系数以及储罐内的初始压力对储罐内的温度剖面的影响。结论是加强储罐外壁的热交换、增大吸附剂的导热系数皆能改善吸附储罐内的温度剖面。
With heat dynamics computation, the typical feature of temperature section plane during discharge in storage system is drawn: the drop extent on storage system axes is the largest. The effects of heat exchage of storage system wall, thermal conductivity of carbon adsorbent, and initial pressure in storage system on temperature profile have been analyzed. The conclusion is drawn that enbancing heat exchange of storage system wall and thermal conductivity of carbon adsorbent can improve temperature section plane of storage system.
