表面活性剂吸收法治理含苯废气的中试实验衣新宇

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):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:表面活性剂;吸收法;苯;中试:TQ123:A:1006-8759(2004)03-0024-04THEMIDDLETESTONTREATINGBENZENEEXHAUSTBYPACKINGSCRUBBERADDEDSURFACTANTYIXin-yu,ZHAOXiu-hua,ZHUDeng-lei(NationalKeyLabonPollutionControl&ResourceResearch,TongjiUniversity,Shanghai200092,China)Abstract:Treatingbenzeneexhaustbypackingscrubberthataddedsurfactants,andanalyzingthewater-additiveabsorptionmechanism.Forthecomplicationoftheexperiment,theoutcomesareanalyzedbyplaning.Throughthecomparisonofthreekindsoffactors(sprayflowinletconcentra-tionsurfactantadditive)byplanning,wegetthefollowingconclusion:forremovalrateofbenzene,inletconcentrationhasthemaximumeffect,waterflowasthefollowing,andsurfactantshavetheleast.Whentheconditionisfulfilled,thebenzeneexhaustcanbedischargedinproperstandard.Keywords:surfactant;absorption;benzene;middletest0,,,;,[1~2]11.1-,[3~5](C6H6),,,,,25e,0.86g/mL,0.0055atm#m3/molEnergyEnvironmentalProtectionVol.18,No.3Jun.,200418320046:2003-12-11:衣新宇(1978-),男,辽宁沈阳人,硕士研究生,主要研究方向为空气污染的治理与评价,,,VOCs,()(),:CH3CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2-COONaCH3CH2###CH2CH2-(),-COONa(),,()[6~8]:(1),Gibbs,(2)(3)(CMC),,,,,,,1.2-,;,:(1)(2),;(3),,,,(4),22.11,A,B,,,,,,,,,,,2.2,,11.;2.10.A/B;3.;4.;5.;6.;7.;8.9.衣新宇等表面活性剂吸收法治理含苯废气的中试实验#25#24253:,20e,400L/h22,,,,30%:,2.32.3.1苯的去除实验10.5%,,33,,,,600mg/m3,2.3.2苯的去除实验21.0%,,44,,,,,,10%~20%,,,,2.3.3苯的去除实验32.0%,,55,,,,3;,,,,50%注:喷淋量123代表的喷淋量分别为200300400L/h;下同31#26#1831264C/(mg#m-3)S/%W/(L#h-1)13000.520024001.030035002.040046003.0L12(3@42)C/(mg#m-3)S/%W/(L#h-1)/%111119.1221234.5331345.9442354.4512119.1622236.6733244.5843364.8913129.21024150.11134258.11244385.6T167.499.5117.5T2121.2110.1173.7T3148.5138.5250.7T4204.8193.8K122.533.229.4K240.436.743.4K349.546.262.7K468.364.6R45.831.433.32.3.4苯的去除实验43.0%,66,,,,3,85%;5,,3,3pH,pH,,,,,,L12(3@42),1,C(mg/m3),S(%),W(L/h)2,:,C4S4W3,85.6%;,:yCyWySC4S4W3,,4,,:,:,,衣新宇等表面活性剂吸收法治理含苯废气的中试实验#27#(下转第39页)0.5%~2.5%Vy)))1,Nm3/kg;CNOx)))NO(mg/Nm3),93.8mg/Nm33.5344,5#4,3,,:,,;,,;,,,,:[1].[M].,1987.[2],.[M].,,1984.[3].(2@25MW),2002./tB4.31@104/%G99/(kJ#kg-1)Qnet,var25912/%A17.75/%S0.44/%N1.48/%K80/%GS0/%dfh80/%Cfh6NO/%B20344/kg6510930342499132643702.180.9516.70.9529867319394594278284,,,,,,/0,:[1],.[M].,2001.[2]NoeldeNevers.AIRPOLLUTIONCONTROLENGINEERING(2nded)[M].McGraw-HillInc.2000.329~395.[3].VOC[J].,1997,17(1):34~38.[4],.--[J].,1995,(6):40~43.[5].-[J].,1999,14(3):19~20.[6].[M].:,2001.2~6.[7]Shen,Y.-H.Removalofphenolfromwaterbyadsorption-floc-culationusingorganobentonite[J].WaterResearch,V36N52002,P1107~1114.[8]Takahashi,Akira;Yang,FrancesH.;Yang,RalphT.Newsorbentsfordesulfurizationbypi-complexation:Thiophene/benzeneadsorption[J].IndustrialandEngineeringChemistryResearch,V41N10May152002,P2487~2496.(上接第27页)183#39#
