摘要: 目前的变压吸附实验中通常使用商品化设备，存在尺寸大、成本高、气路复杂等问题，不利于大规模开展本科实验教学。本文对变压吸附装置进行了小型化、低成本化改进，学生可以使用实验室常见材料自行搭建变压吸附装置，了解并掌握设备搭建、调试、运行的整个流程。以Li交换分子筛作为吸附剂，该设备的制氧效果与商用制氧机相当，出口氧气浓度可达95.8%。该装置具有安全性高、可反复拆装的特点，搭建、调试过程具有一定趣味性，适合用于应用化学、化学工程等本科专业的变压吸附实验教学，有利于激发学生对创制实验装置的兴趣，锻炼学生的动手能力，提高学生理论结合实际解决问题的能力。

Abstract: At present, commercial systems are usually used in pressure swing adsorption (PSA) experiments. However, the purchased equipment has disadvantages such as large size, complicated tubing design and high price, which are not conducive to undergraduate laboratory teaching. In this paper, a low-cost benchtop design of PSA system is proposed, with which students can build their own PSA equipment with common laboratory materials and conduct the testing and operation on their own. Using Li-exchanged zeolite as the adsorbent, the system can produce high-purity oxygen with a concentration up to 95.8%, which is comparable to that of commercial oxygen concentrator. The designed system can be disassembled and reassembled repeatedly and the process of building and testing is safe and fun. The proposed design can be used in the PSA experimental teaching for undergraduate students who major in applied chemistry, chemical engineering and other related subjects. We believe that students' interest in creating experimental equipment can be intrigued and their ability to solve practical problems can be improved during the build and testing process of the proposed PSA system.
