有机废气处理特点
有机废气处理特点:有机废气一般都存在易燃易爆、有毒有害、不溶于水、溶于有机溶剂、处理难度大的特点。在有机废气处理时普遍采用的是有机废气活性炭吸附处理法、催化燃烧法、催化氧化法、酸碱中和法、等离子法等多种原理。一般推荐使用等离子法,因为低温等离子法具有去除效率高使用方便的特点。比较好的有机废气处理方法是催化氧化净化系统,废气处理设计周密、层层净化过滤废气,效果较好。但要看到无论哪一种等离子都是以高压放电为主,产生放电打火,日本大阪大学1991年10月2日16时,就发生等离子体爆炸,当场炸死2人,轻伤5人。所以不建议在化工医药行业运用。
Characteristics of organic waste gas treatment: organic waste gas is generally flammable, explosive, toxic and harmful, insoluble in water, soluble in organic solvents, and difficult to treat. In the treatment of organic waste gas, many principles are commonly used, such as adsorption, catalytic combustion, catalytic oxidation, acid-base neutralization, plasma and so on. Plasma method is generally recommended because of its high removal efficiency and convenient use. A better treatment method of organic waste gas is catalytic oxidation purification system. The design of waste gas treatment is thorough, and the effect is better. However, we should see that no matter which kind of plasma is mainly high-voltage discharge, which produces discharge and ignition. At 16:00 on October 2, 1991, Osaka University in Japan, there was a plasma explosion, killing 2 people and slightly injuring 5 people on the spot. Therefore, it is not recommended to use it in the chemical and pharmaceutical industry.
