蓄热式催化净化装置
本技术涉及废气环保处理设备
,具体涉及一种蓄热式催化净化装置。
技术介绍
目前,大气污染是我国最突出的环境问题之一,工业废气是大气污染的主要来源,工业有机废气主要包括碳烃化合物、苯及苯系物、醇类、酮类、酚类、醛类、酯类、胺类、腈、氰等有机化合物,主要来自汽车尾气,电子、化工、石油化工、涂料、印刷、涂装、家具、皮革等行业产生。现有的废气处理设备结构简单,主要通过滤网等过滤结构进行过滤,滤网过滤周期短,滤网吸附一旦饱和而未及时更换,不但起不到净化效果,还会因为滤网吸附的污染物被重新排回室内而导致二次污染。
技术实现思路
本技术针对现有技术存在的不足,提供了一种蓄热式催化净化装置。本技术解决其技术问题所采用的技术方案是:一种蓄热式催化净化装置,包括主平台、阻火器、催化燃烧机构、干式过滤器、前活性炭吸附箱、后活性炭吸附箱和主引风机,有机废气源通过管路与阻火器相连,阻火器由多层丝网组成,催化燃烧机构内置催化燃烧器和换热器,催化燃烧器内置多层蜂窝状催化剂,阻火器出口换热器的管程进口相连,换热器的管程出口与催化燃烧器进口相连,催化燃烧器出口与换热器的壳程进口相连,换热器的壳程出口与干式过滤器相连,干式过滤器出口气体先后进入前活性炭吸附箱和后活性炭吸附箱,后活性炭吸附箱出口与主引风机相连,主引风机的出口气体通过烟囱放空。上述有机废气源的出口管路上设置排空阀门,必要时可以直接放空,例如净化装置检修时。本净化装置采用催化燃烧法,将有害气体转化成无害气体。具体方 ...
