本文主要研究内容
作者薛冬冬(2019)在《LED光催化反应器研发与实验研究》一文中研究指出:随着半导体技术的发展,LED的应用也愈发广泛,不仅在照明领域获得了广泛应用,在非照明领域也具有相当的优势。本论文主要目的在于使用LED对光催化反应器的光源结构进行研究及设计,并对水中有机污染物在不同光源下的降解效果进行实验研究。首先,使用软件SolidWorks和LightTools对纳米晶导光板进行仿真设计。以波长为365nm的紫外2835LED作为光源,PMMA材料为导光板基材并分别掺入二氧化硅和氧化铝粒子进行建模、仿真和分析。仿真结果表明,在导光板尺寸为600mm*300mm*4mm时,掺入氧化铝粒子的光耦合效率和光照均匀度均优于掺入二氧化钛粒子,可分别达到70%和80%以上,为选择特种波长的纳米晶导光板提供了一定的参考价值。其次,选择合适的纳米晶导光板制作紫外双面出光光源,并进行防水处理。将光源与适当的驱动电路及反应容器相结合,构建紫外光催化反应器。将反应器中的紫外光源浸入污染液中且等间隔平行排列,催化剂负载于泡沫镍之上,置于两紫外光源之间。采用此浸入式正光催化结构对一定浓度的甲基橙溶液进行降解实验。实验结果表明,在365nm的紫外光源下采用浸入式正光催化结构时,对甲基橙溶液的降解率为23.21%。在较低浓度时甲基橙溶液对365nm的紫外光存在较强吸收,可使用背光催化结构加以改进。最后,测量可见光催化剂HSNO-CdS的吸收谱,并以此作为目标进行LED光谱构造。通过计算得出各种单色LED的组合比例并按实际应用情况进行放大,制作过程中使各种单色LED的排布尽可能均匀。对光源进行防水处理后,将其平行放置于污染液中。反应器中的催化剂存在形式为悬浮式。实验结果表明,140min内通过光谱构造技术制作的双面出光光源对2760ml的甲基橙溶液的降解率为43.55%;相同条件下,普通白光光源对甲基橙的降解率仅为23.11%。
