| 摘 要： | 建立了两塔径向流变压吸附制氧实验装置,研究了径向流吸附器的气体流动型式、外流道宽度和流道结构对制氧效果的影响.结果表明:对于变压吸附制氧,径向流吸附器采用向心流动最为合适;在实验条件下,外流道宽度减小到13 mm时,氧和氮分离效果最佳;与Z型流道相比,∏型流道结构改善分子筛的利用率,产氧效果最好.

| Abstract: | A radial flow pressure swing adsorption (PSA) unit with two-tower configuration was designed for oxygen production. The influences of gas flow pattern, outer flow channel width and channel structure on oxygen production were studied by experiment. The result indicates that it is an optimal choice to use centripetal flow in the radial flow adsorber for oxygen production with PSA. Un-der the experimental condition, when the outer flow channel width decreases to 13 mm, the separation of oxygen from nitrogen is the best. A R-shaped channel structure can better improve the utilization efficiency of molecular sieves and oxygen production compared with a Z-shaped channel. This research result provides a foundation for the application and research of a radial flow adsorber in the PSA unit for oxygen production. |
