1、旋膜式除氧器讲明书-中英文旋膜式除氧器安装、使用讲明书Rotaryfilmtypedeaeratorinstallation,operationinstruction一、旋膜除氧器的设计特征one,rotarymembranedeaeratordesignfeatures旋膜除氧器,是一种新型热力除氧器,可用于定压、滑压、负压等方式运行,适应于各类电站锅炉、工业锅炉给水及热电厂补给水或热用户用水的除氧。Rotarymembranedeaerator,isanewtypeofthermaldeaerator,canbeusedforconstantpressure,slidingpressure
2、andnegativepressuremeanssuchasoperation,suitableforallkindsofpowerstationboiler,industryboilerfeedwaterandthermalpowerplantsupplieswaterorhotwaterusersofoxygen.旋膜除氧器的设计特征是:Rotarymembranedeaeratordesignfeaturesare:利用气体在水中的溶解特性,通过加热蒸汽,将进入除氧器的补给水、凝结水包括各种疏水加热到与除氧器内部压力相对应的饱和温度。根据亨利定律和道尔顿定律,溶解水中的氧和二氧化碳等非冷
3、凝气体自水中析出,由顶部排气管排入大气,使水中的含氧量到达规定的标准,合格的除氧水储存在除氧器下部的水箱中,随时准备锅炉给水的需要。Usinggasinwaterdissolvingcharacteristic,throughtheheatingsteam,willenterthedeaeratorsupplywater,condensate(includingallkindsofhydrophobic)heatingtothedeaeratorinternalpressurecorrespondingsaturationtemperature.AccordingtoHenryslawandD

5、用热电厂,热电厂的补给水量大补水率最大要求100,补给水温低最低要求15,含氧量高约10000ug/L。一般除氧器在这种条件下,难于将补给水中溶解氧排除到到达规定的标准。因而,往往将热力系统设计,为大气式及压力式除氧器两级串联运行方式,即补给水先送入大气式除氧器,经一次除氧后再送入压力式除氧器进行二次除氧,既增加了设备与运行操作,又增加了厂房建筑面积。Rotarymembranedeaerator,becausehavetheabovetechnicalcharacteristics,particularlyforthermalpowerplant,thermalpowerplantsuppl
