摘要:
根据相关标准及理论,设计了一种新型的冷凝吸附耦合的板式吸附床,并采用实验的方法,对油气回收过程中板式吸附床冷凝吸附过程的传热现象进行了研究。分别采用平均颗粒直径为2.36~3.35 mm和0.59~0.85 mm的活性炭颗粒作为吸附剂,实验过程对不同吸附时间、不同颗粒直径等实验条件下床层内温度及压力分布情况进行了测量。结果表明:冷凝吸附过程受时间及孔隙率的影响较大,适当提高床层孔隙率有利于提高吸附床的传热效果,与传统的工业用吸附床相比,冷凝吸附耦合的结构可以有效降低吸附过程中床层的温度,将吸附温度控制在15 ℃以下,床层温升≤25 ℃。
Abstract:
A new kind of adsorbed packing bed was designed to investigate the heat transfer during the process of oil recovery.Two kinds of spherical activated carbon particles with different diameters 2.36-3.35 mm and 0.59-0.85 mm were used as adsorbents.Temperature and pressure data of the bed were obtained for different adsorbent particles.Results showed that adsorption time and the porosity had an obvious effect in the heat transfer process when the condensation and the adsorption occurred at the same time.Compared with the traditional packing bed,the new adsorbed packing bed was more effective for heat and mass transfer during the process of desorption and adsorption in oil recovery,the mean temperature of the bed could be controlled at the temperature of 15 ℃,the temperature rise could be controlled in the ranges of 25 ℃.
