【摘要】医用分子筛制氧设备是以沸石分子筛为吸附剂,用变压吸附法制取医用氧气的设备(以下简称制氧机)。该设备是在常温低压下以空气为原料,将空气中的氧气用物理的方法直接分离,制取浓度为90%～96%的氧气,剩余的成分主要是氩和氮。本文通过对医院应用供氧方式的对比,说明分子筛制氧设备应用于医院供氧的优越性,并对目前国内采用医用分子筛制氧设备性能不稳定问题,进行了总结分析,提出了改进技术。

    【Abstract】Medical oxygen equipment is zeolite molecular sieve as adsorbent, with PSA Preparation of medical oxygen equipment, The device is under low pressure at room temperature using air as raw material, the oxygen in the air directly separated by physical means, preparation concentration of 90% to 96% oxygen, the remaining components are mainly argon and nitrogen. Oxygen supply through the application of this method of hospital comparison shows that oxygen molecular sieve oxygen generator used in the superiority of the hospital, and domestic use of medical equipment performance molecular sieve oxygen generating instability, were analyzed, the improved technology.

    引言

    医用分子筛中心制氧系统主要由空气压缩机、空气过滤器、空气贮罐、吸附塔、氧气氧气作为医院医疗使用已经有很多年的历史,在医疗行业也是不可缺少的,但其制取方法一直延用着传统的低冷空气分离法,使用该方法制氧设备投资高、占地面积大,操作及维修维护费用多,因此不便在医院推广使用 ......
