简介:【摘要】我国当前大气污染状况不容乐观。室内空气污染的主要污染物为挥发性有机污染物,会严重影响室内空气质量并影响人体健康。光催化就是基于阳光直接照射的环境条件下光催化剂的氧化还原能力,可以达到实现净化环境中的污染物、材料合成和转化的目的。从反应器改进的角度和操作参数探索提高光氧化效率的途径。从管道的选材设计和管道的结构设计,选择fep(聚全氟乙丙烯)作为内置管,并将紫外灯至于内部实现静态混合器内部发光。通过实验探究聚全氟乙丙烯内置管以及紫外灯内部发光装置对甲醛气体的浓度变化影响。研究结果表明:在高浓度和低浓度甲醛环境下,聚全氟乙丙烯内置管以及紫外灯内部发光装置对甲醛气体的浓度无明显影响。设备在实验过程中呈现出高效混合反应,密封防爆炸效果。且拆卸方便与相关部件的衔接、成本、催化剂负载效果好。同时
