摘要: 以活性氧化铝为吸附剂材料,选取5.5~6.5 mm及4~5 mm两种粒径的活性氧化铝对压缩空气进行除湿实验研究,为活性氧化铝在压缩空气除湿系统中的运行提供依据。结果表明:在温度120℃、压力0.2 MPa、流量40 m3/h的条件下,5.5~6.5 mm活性氧化铝的再生性能优于4~5 mm活性氧化铝;在温度120 ℃、压力0.7 MPa、流量15 m3/h的条件下,前期在1200 s时间内,两者的吸附速率都很快,后期4~5 mm粒径的活性氧化铝的吸附稳定性更好。在给定的工况条件下,5.5~6.5 mm活性氧化铝再生效果比4~5 mm活性氧化铝要好,但吸附效果不如后者。

Abstract: In this paper,5.5—6.5 mm and 4—5 mm two different particale diameter of activated aluminal were taken as the adsorbent to carry out the experimental study on the adsorptive dehumidification performace. The purpose of the experiment is to provide the basis for the operation of activated alumina in compressed air dehumidification system. The results shown that the regeneration performances of 5.5—6.5 mm activated aluminal molecular are surperior to 4—5 mm when the temperature is 120 ℃ and the air rate is 40 m3/h and the pressure is 0.1 MPa. At the conditions of the temperature is 35 ℃ and the air rate is 15 m3/h and the pressure is 0.6 MPa,early in the 1200 s time,both activated aluminals’ adsorption rate are vary fast,and late 4—5 mm particle size of the activated alumina adsorption stability is better. Conclusion:in the given condition,5.5—6.5 mm activated alumina regeneration effect of activated alumina is better than 4—5 mm,but the adsorption effect than the latter.
