采用化学聚合法强化吸附剂——沸石颗粒的热传导性能,利用苯胺单体在沸石颗粒表面氧化聚合,使少量的聚苯胺形成均匀连续的导热性能好的高分子材料网,在实验条件下可使该种吸附剂的有效导热系数提高到原来的4倍多。同时,将强化后的吸附剂挤压成型,进行强化吸附床层的传热研究,结果表明堆积密度为原来的1.5倍的成型块,其有效导热系数比原来提高30％,对比混合法的实验和数据分析表明,化学聚合法较物理混合法效果更明显,是一种适宜吸附剂热传导强化的新途径。
Adopting chemical polymerization method to strengthen the thermal conductivity of the adsorbent-zeolite particles, the aniline monomer is oxidized and polymerized on the surface of the zeolite particles so that a small amount of polyaniline forms a uniform and continuous network of polymer materials with good thermal conductivity, under experimental conditions The effective thermal conductivity of the adsorbent increased to more than 4 times. At the same time, the strengthened adsorbent was extruded to enhance the heat transfer of the adsorbent bed. The results showed that the bulk density was 1.5 times that of the former, and the effective thermal conductivity was increased by 30% And data analysis shows that the chemical polymerization method is more effective than the physical mixing method, which is a new way for the heat transfer enhancement of the adsorbent.
