BBQ型系列高速表面曝气机BBQSeriesHighSpeedSurfaceAerator一、概述SummaryBBQ系列高速表面曝气机是我公司在参照国外同类产品的基础上，自行研制开发的系列产品，经几代样机的试验，建立起先进的水力模型，并在污水处理厂投入使用，效果良好。高速表面曝气机主要用于工业废水及生活污水的生化法处理曝气池中，通过对污水进行充氧、搅拌，使水中好氧菌与氧气充分接触，从而达到快速、高效处理污水的目的。本产品也可以用于水产养殖等池中的充氧。OurBBQSeriesHighSpeedSurfaceAeratorisbasedonsimilarforeignequipmentanddevelopedwithinourownR&Dfacility.Afterseveralgenerationsofimprovementandoptimization,、ve'vedevelopedourownadvancedhydraulicmodel.Theaeratorhasproveditsqualityandeffectivenessinmanywastewatertreatmentplants.ItisbestsuitedinthebiochemicaltreatmentofindustrialwastewaterItcaneffectivelymixandoxygenatethewatei;providingsufficientoxygentoaerobicbacteria・Thisproductcanalsobeusedtooxygenatethewaterinaquacultlire.BBQ|I'电机功率KW(MotorPowerkW)高速表面曝气机(HighSpeedSurfaceAerator)二、工作原理OperatingPrinciple根据水力机械的设计原理进行设计，叶轮与电机直联，以获取高速旋转，将液体吸起后高抛，形成水幕。液体在飞行过程中与空气接触而溶氧，同时，被抛液体落下时撞击液面形成波浪，使水中含氧增加。叶轮在池内形成足够强的速度场以防止活性污泥的沉淀，兼备了搅拌功能。Theaeratorisdesignbasedonhydraulicmachinery.ToachievehighRPM，theimpellerisconnecteddirectlytothemotorWaterisdrawninfromthebottomandsprayedoutwards,creatingacurtain.Duringflight,waterisoxygenatedbecauseofthelargesurfacearea.Asthewaterdropsdown，splashesarecreated,providingfurtheroxygenation.Theimpelleralsocreatesenoughmovementofthewatertopreventthesedimentationofactivesludge.三、结构及特点ConstructionandCharacteristicsBBQ系列表面曝气机由电机、甩水盘、叶轮、浮筒、导流圆筒等主要部分组成(见图1),有如下特点：TheBBQseriessurfaceaeratormainlyconsistsofthemotor,waterswingplate，impellei;buoyandflowguidetube.Ithasthefollowingcharacteristics.\n图1BBQ型高速表面曝气机外形简图Figure1BBQSeriesHighSpeedSurfaceAeratorOutlineDiagram1、先进的水力模型设计，使叶轮与介质间的比表面压力较低，有效地提高了动力效率。2、叶轮与电机直联，使叶轮保持高速旋转，从而获取足够的提升流量。液体在强大的动能作用下，抛撒距离远，形成水幕范围广，充氧量大。同时，液体在一定范围内呈现紊流场，兼备了搅拌功能。3、增加了多道甩水环、密封环等其它零件，阻止污水渗入电机，延长电机使用寿命。4、除电机外，本曝气机所有零部件均选用不锈钢，抗腐蚀性能强，能适应不同污水水质的处理要求。5、由于采用了漂浮式结构，曝气机与水面相对位置无需调节，无需安装基础，只用四根缆绳与岸边锚桩固定即可，适应各种曝气池型。6、与其他曝气机相比，本产品具有结构简单、重量轻、安装维修方便等特点。1・Advancedhydraulicmodelisusedtomakethesurfacepressureratiobetweentheimpellerandmediumlow,soeffectivelyincreasingtheefficiency.2.ImpellerisdirectlyconnectedtothemotorThehighspeedrotationensuressufficientliftingpowei;creatingalargewatercurtain.Atthesametime,theturbulencecreatedprovidesthemixingfunction・3・Anumberofwaterswingringsandsealswereaddedtopreventwaterdamagetothemotor.\n4.Exceptthemotoi;allcomponentsoftheaeratoraremadeofstainlesssteel.Thereforeitishighlyresistanttocorrosionandcanbeusedinthetreatmentofallkindsofwastewaten5.Becauseoftheuseofthefloatingconstruction,thereisnoneedtoadjustthedistancebetweentheaeratorandthewatersurfaceandnoneedforinstallationfoundation^onlyfourcablesarerequiredtosecuretheaerator;Itcanbeusedinaerationtankofallkindsofshapes.6.Comparedtoothertypesofaerator,thisonehastheadvantagesofsimpleconstruction,lightweightandeasymaintenance.四、规格及技术参数SpecificationsandTechnicalParameters表1BBQ系列高速表面曝气机技术参数Table1BBQSeriesHighSpeedSurfaceAeratorTechnicalParameters型号Model叶轮直径ImpellerDiameter电机功率MotorPower充氧豪OxygenationRate流«FlowRate最大混合深度MaximumMixingDepth整机质■MassmmkWkg02/hm3/hm(max)kgBBQ64)1835.57.54503.0230BBQ84)2007.5106003.5290BBQ154)21315209304.0365BBQ224)3OO222913004.5550表2曝气池尺寸(供参考用)Table2AerationTankDimensions型号Model容积Volume(m)宽度WidthA(m)最大深度MaximumDepthH(m)BBQ6220-2708-8.83.5BBQ8290-4008.5-104.0BBQ15550-65011-124.5BBQ22850-110013-155.0说明：方形曝气池内不设柱子、池壁平整光滑为佳；长方形池子长宽应比小于1.5O如设计圆形池，直径与方池宽度相同。Note:Thereshouldnotbeanypolesorotherobstructionsinsquareaerationtanks.Thesidewallsarebestflatandsmooth;thelengthtowidthratioforrectangularaerationtanksshouldbelessthan\.5.Ifthetankiscirculai;thenthediametershouldbethesameassquaretanks.五、安装及用户须知InstallationGuide1、根据系统的需氧量选配本产品，并根据曝气池大小安装于适当的位置。2、订货时用户应提供曝气池大小及安装位置，以便确定固定设备之用的缆绳长度和电缆长度。3、如用于水产养殖池增氧，务必清理设备3米直径范围内的水草杂物，同时增设网拦，防止\n养殖物受到伤害。4、供货时本公司提供更为详细的安装、调试和维护说明及完善的技术服务。1.Themodelshouldbedeterminedbasedontheoxygenationrequirementofthesystem.Theinstallationlocationdependsonthesizeofthetank.2.Whenplacingtheordei;thetanksizeandplaceofintendedinstallationshouldbespecifiedsothelengthofthefasteningcableandelectriccablecanbedetermined.3・Iftheaeratorisusedinaquaculture,weedsandotherdebriswithina1<5meterradiusmustbecleared.Netsshouldalsobesetuptopreventthewaterproductfromgettingcaughtintheaerator.4.Upondeliveryoftheproduct,wewillprovidedetailedinformationoninstallation,adjustmentandmaintenanceaswellastechnicalsupport.图2BBQ型高速表面曝气机安装简图Figure2BBQTypeHighSpeedSurfaceAeratorInstallationDiagram
