摘　　要：针对能源与环境系统工程专业的实验教学和科研需要,设计了一套连续式光催化降解系统综合实验平台。平台主要由恒温槽、蒸汽发生器、光反应器、控制单元、检测系统等组成,可调节控制反应过程中的光照强度、相对湿度等多个反应条件,保证了连续稳定的催化剂活性测试条件。该系统利用光能与催化剂的相互耦合,可实现挥发性有机污染物(VOCs)的高效催化降解及机理分析,并结合在线检测手段,实现对催化剂的活性、寿命、中毒的评价,以及各个工况条件下的不同催化剂的光降解效果评定。此外,还可开发与光催化相关的综合性实验,满足科研与专业教学需要。In order to satisfy the experimental teaching and the specialty of Energy and Environment System Engineering, this paper designed a set of integrated platform of photo-catalytic degradation system. This platform consists of the thermostatic bath, steam generator, light-reactor, control unit, detection system, etc., it can control light intensity, relative hmnidity, and other reaction conditions during reaction process to ensure a continuous and stable test environment for catalyst activity. The combination of the solar energy and the effective catalysts can degrade VOCs with high efficiency, and their degradation pathways can be analyzed. Integrated with online detection technologies, this system can evaluate the activity, lifetime and poisoning of catalysts, as well as the ultimate photo-degradation results for different catalysts under various conditions. In addition, this platform can conduet comprehensive experiments related to photoeatalysis in order to meet the needs of research and teaching.
