For portable oxygen concentrator by pressure swing adsorption (PSA) method, its volume, mass, power, oxygen flux and oxygen saving efficiency are the most important parameters which are affected strongly by the PSA cycle. In this paper, we propose a new pressure equalization step to optimize the PSA cycle. According to the experimental results, when the product ends of two beds are connected and the feed gas is switched from the high pressure bed to the low pressure bed during the pressure equalization step, the system has a larger oxygen flux, a less energy consumption and a more simple structure.
对于采用变压吸附（PSA）方法的便携式氧气浓缩器而言，其体积、质量、功率、氧气流量和氧气节省效率是受PSA循环强烈影响的最重要参数。在本文中，我们提出了一种新的均压步骤来优化PSA循环。根据实验结果，在均压步骤期间，当连接两个吸附床的产物端并将原料气从高压床切换至低压床时，该系统具有更大的氧气流量、更低的能耗以及更简单的结构。
