摘要:

采用静态法测定了蜂窝状块体硅胶/分子筛复合物的吸附性能,并采用吸附床结构模拟转轮除湿过程,测定了复合物动态吸附性能;探讨了复合物在吸附过程中温、湿度分布;研究了处理风参数(风速,进口温度、湿度)对块体吸附剂吸附性能的影响。结果表明:块体硅胶/分子筛复合物的除湿性能明显高于硅胶,尤其在较高温度和较低湿度条件下。在处理风温度较低、风速较小及处理风湿度较大的前提下,块体复合物除湿性能较好。

Abstract:

The static adsorption performance of honeycomb monolithic silica gel/molecular sieve composites(HMSMC)was tested,and their dynamic adsorption performance was also measured by using adsorbent bed to simulate the dehumidifying process of rotary-type dehumidifierThe distribution of temperature and humidity inside HMSMC during adsorption and the influences of processing air parameters,such as temperature,humidity and speed on adsorption performance were discussedThe results of experiments showed that the dehumidifying performance of HMSMC excelled honeycomb monolithic silica gel(HMSG),especially under high temperature and low humidity conditionsHMSMC had excellent dehumidifying ability under the low processing air temperature,low air speed,or high relative humidity condition.
