摘要
针对电子线路板厂洁净房丝印区有机废气污染的问题,选择间歇式固定床活性炭吸附法净化有机废气的工艺流程,通过制冷能力和吸附量的估算,设计空塔气速为0 . 6m s,吸附剂为果壳活性炭,装填高度为1m ,分双层多个抽屉式填装,运行后,实际监测净化效果明显,苯、甲苯、二甲苯的净化效率分别为81 .5 9% ,83. 5 0 % ,85 . 4 3% ,换下的废活性炭经再生解吸后可循环使用。回收的有机溶剂掺在柴油中作为发电机的燃料。
The flowchart of the intermittent fixed be active carbon adsorption for purification of the organic waste gas was selected in accordance with the organic waste gas pollution problems from the wire printed district of the printed circuit board plant.Through the calculation ability of the causing cold and quantitites of the adsorption.some parameters of the activated carbon adsorption are designed, such as the gas velocity of the empty tower was about 0.6 m/s,the activated carbon is coconut.The activated carbon adsorption bed was designed as double story with drawers.After the adsorption bed purification,practical monitor testified: the efficient of the benzene.toluene and xylene purified to 81.59%, 83.50%, 85.43% by adsorption.The waste activated carbon was accumulated and desorption.The recycle organic products were mixed into the diesel oil to be used as fuel of motors.
