说说废气处理技术中心的UV光解技术
技术 2019-05-24 19:00:02 字数:2269

昨天发表了一篇关于造纸业废水处理工艺相关的文章,下面收到一读者的评论说最近在研究UV光解,因此,小编就在网页上各种搜集,大致了解了一下关于这位读者所说的UV光解技术!

其技术常用于喷涂、烤漆、塑料、印刷、食品、饲料、养殖、污水厂、垃圾站等行业中低浓度的VOCs有机废气处理。主要是利用高能紫外线光束照射恶臭气体(工业废气)分子键,裂解恶臭气体物质如:苯、甲苯、二甲苯、非甲烷总烃、酯类等、氨、三甲胺、硫化氢、甲硫氢、甲硫醇、甲硫醚、二甲二硫、二硫化碳、苯乙烯,硫化物等VOC气体的分子键,使呈游离状态的污染物原子与臭氧氧化聚合成小分子无害或低害物质,如CO2、H2O等。

说说废气处理技术中心的UV光解技术

而其核心技术主要是利用高能紫外线灯,紫外线灯管所发出的紫外线光谱由所选用的石英材料来确定。因此,紫外线灯管的材料与制作技术工艺直接决定了灯管的品质。由于目前还还没有UV光解灯的国家标准,因此建议大家在辨别市场上的灯管时尽量谨慎,同时这也是关于UV光解技术的一个缺点!

UV光解技术不仅在灯管选择上存在缺陷,同时这种技术在对高浓度及超大风量工程方面的处理技术也是不佳的,例如对于医疗、石油化工等行业超大风量、高浓度废气处理方面效果并不是很理想,需要采用其他废气处理技术进行前期的处理,待风量和浓度降低时,再采用UV光解协助处理,当然这种技术对前期的处理也是有一定的要求的,并且其设备需要定期的保养和维护!

当然UV光解技术的成本和能耗都比较低,设备便于维护和安装,对中低浓度、中小风量的VOCs有机废气净化效果明显,能够处理苯、甲苯、二甲苯、非甲烷总烃、酯类等多种VOCs有机废气,对恶臭气体及其它刺激性异味有立竿见影的清除效果,如:CO2、H2O等!

上述关于UV光解技术的内容,本人只是初步了解,对专业性的还不是深入,因此关于上述内容或者专业性的表述有不妥之处,请谅解!同时阅读者也可在下方留言点评,谢谢!
