| 摘 要： | 研究了气源温度和解吸条件对制氧效果的影响,结果表明:细长解吸管路会导致吸附塔内氧浓度波前沿在吸附周期内极易穿透床层,在产氧期及间歇期都会有低浓度氧流入储氧罐,造成氧浓度和流量下降;较高的气源温度有利于分子筛解吸再生,在15～65℃内,平均每升高10℃,产氧体积分数可以提高1.2%。

| Abstract: | The temperature of feed air and desorption parameters,such as the inner diameter and length of the pipe for desorption were measured in oxygen generation by pressure swing adsorption.The result showed that thinner and longer pipe could lead to more easy penetration of oxygen in adsorption bed during the adsorption step.Oxygen with a lower concentration would reach the top of the adsorption bed during adsorption and desorption,resulting in lower oxygen concentration and decreased flow rate.The feed air with ... |
