本文以硅胶作为吸附剂,对特定结构的固定床固体吸附除湿性能进行了实验研究。通过对吸附床体进出口温湿度的测量,分析了进口湿空气温度和含湿量在吸附除湿阶段对除湿结果的影响。结果表明,硅胶在湿空气进口温度为28℃时的固定床除湿量比30℃时平均多31.6%,湿空气进口含湿量为22.49 g/kg干空气时的除湿率比17.64 g/kg干空气时平均高出4.3%。
In this paper, silica gel as an adsorbent, fixed-bed solid-specific adsorption of a specific solid adsorption dehumidification performance of an experimental study. Through the measurement of the temperature and humidity of the inlet and outlet of the adsorption bed, the influence of the inlet humid air temperature and moisture content on the dehumidification results during the adsorption and dehumidification stages was analyzed. The results showed that the dehumidification capacity of silica gel at the wet air inlet temperature of 28 ℃ was 31.6% more than that at 30 ℃, and the dehumidification rate of dry air with wet air inlet moisture content of 22.49 g / kg was 17.64 g / kg dry Average 4.3% above air.
