利用吸附-催化燃烧法处理喷漆产生的有机气体

描述了采用吸附-催化燃烧法处理喷漆过程中产生的有机气体（苯）的处理工艺过程及装置。，开展了如下设计：利用吸附一催化燃烧法处理喷漆废气，进气流量为45000m^3/h，主要污染物为苯，浓度为150mg／m^3。工艺流程如下：有机气体首先通过预过滤器去除漆雾，然后利用三组蜂窝状活性炭吸附床对其依次进行24h连续的吸附，同时对吸附饱和的另一组活性炭床进行8h的脱附。通过80～100℃热风的吹脱作用，将大风量、低浓度（Q=15000m^3／h，C=150mg／m^3）的有机废气浓缩成小风量、高浓度的有机废气（Q=2500m^3／h，C=900～1500mg／m^3），并经过催化燃烧室将有机气体转变成无害的CO2和H2O，并保持稳定的自燃烧状态。与传统工艺相比，整个系统采用PLC程序控制，该方法具有净化效率高、无二次污染、运行成本低的优点。

Treatment of Organic Waste Gas from Spray-Paint by Abaorption-Catalytic Combustion

In this paper,adsorption-catalytic combustion technology process and equipment which was used to treat organic gas(benzene)from spray-paint were discussed.An equipment of absorption-catalytic combustion to treat organic gas of spray-painting was desigened.Q was 45000 m3/h.The main pollution was benzene,and the concentration was 150 mg/m3.The technological process was as follows: waste gas was firstly pretreated with painting removal and filtration equipment,then continuously ran through honeycomb-shaped act...
