导读:有机化工废气是大气污染源中的一种重要成分,不同的化工企业因其生产产品以及加工工艺不同,所产生的废气种类和性质也是不同的。一般是由于燃烧锅炉所产生的烟尘以及加工过程中所产生的废气。有机化工废气因其特殊性,一般具有如下特点。

有机化工废气特点

1、排放物大多都有刺激性或腐蚀性。

2、废气中浮游粒子种类多、危害大。

化工生产排除的浮游粒子包括粉尘、烟气、酸雾等,种类繁多,对环境的危害较大。特别当浮游粒子与有害气体同时存在时能产生协同作用,对人的危害更为严重。

有机化工废气处理几种常用的处理方法及利弊分析:

1)燃烧法

广西快3RANSHAOFAZHUYAOYOUGENJURANSHAODEWENDUJIFUZHUJIEZHIBUTONGYOUFENWEIZHIJIERANSHAOFAHECUIHUARANSHAOFALIANGZHONG。

催化燃烧法较适合于高浓度、小风量化工废气的净化,在处理低浓度的废气时,由于要维持300~400℃的催化燃烧温度,需借助于活性炭吸附广西快3等浓缩工艺来提高废气的燃烧热值,但化工废气中的水气、油污及颗粒物易引起活性炭吸附容量下降及催化剂中毒失活等问题,使得该方法的推广和使用在一定程度上受到了限制。
