摘　　要：以尼龙酸甲酯(DBE)为吸收剂,经超微雾化吸收治理乙酸乙酯或甲苯废气。此法适合于治理质量浓度>25 m/L乙酸乙酯废气或质量浓度>10 mg/L的甲苯废气,单次循环吸收剂DBE损耗量<5%。在12～13℃时,乙酯乙酯最大吸收率为80.6%,甲苯最大吸收率为92.7%,总回收率>95%。吸收后的尾气质量浓度与理论计算结果具有很好的一致性。实验尾气经纳米活性炭吸附净化,实现零排放。The waste gas of the ethyl acetate or toluene is absorbed by the ultra micro-droplets with the nylon acid methyl ester（DBE） as the absorbent.This method is suitable for the treatment of ethyl acetate waste gas with ethyl acetate concentration 25 mg/L or toluene waste gas with toluene concentration 10 mg/L.The absorbent loss is 5% by single circulation.At 12-13℃,the maximum absorption rate of ethyl ester and toluene are 80.6% and 92.7%,respectively.The total recovery rate is 95%.The tail gas concentration after absorption has good consistency with the theoretical calculation result.The experimental tail gas is purified by nano-activated carbon and achieves zero emission.
