表面活性剂吸收法治理含苯废气的中试实验

表面活性剂吸收法治理含苯废气的中试实验表面活性剂吸收法治理含苯废气的中试实验衣新宇,赵修华,朱登磊(同济大学污染控制与资源化研究国家重点实验室,上海200092)摘要:采用添加表面活性剂的填料塔来吸收治理含苯废气,分析了水-吸收剂的吸收机理。考察了喷淋量、废气入口浓度和表面活性剂添加量这三个因素对苯去除率的影响。结果表明,对苯来说入口浓度对去除率的影响最大,喷淋液体流量次之,表面活性剂的影响最小。条件满足时,含苯废气可以达标排放。关键词:表面活性剂;吸收法;苯;中试中图分类号:TQ123文献标识码:A文章编号:1006-8759(2004)03-0024-04THEMIDDLETESTONTREATINGBENZENEEXHAUSTBYPACKINGSCRUBBERADDEDSURFACTANTYIXin-yu,ZHAOXiu-hua,ZHUDeng-lei(NationalKeyLabonPollutionControl&ResourceResearch,TongjiUniversity,Shanghai200092,China)Abstract:Treatingbenzeneexhaustbypackingscrubberthataddedsurfactants,andanalyzingthewater-additiveabsorptionmechanism.Forthecomplicationoftheexperiment,theoutcomesareanalyzedbyplaning.Throughthecomparisonofthreekindsoffactors(sprayflow、inletconcentra2tion、surfactantadditive)byplanning,wegetthefollowingconclusion:forremovalrateofbenzene,inletconcentrationhasthemaximumeffect,waterflowasthefollowing,andsurfactantshavetheleast.Whentheconditionisfulfilled,thebenzeneexhaustcanbedischargedinproperstandard.Keywords:surfactant;abs
