凝汽器化学清洗配方

凝汽器化学清洗配方热电厂凝汽器化学清洗配方的试验研究及工业应用欧阳志(金陵石化公司化肥厂水处理中心,江苏南京210033)[摘要]在不停车的情况下,为去除热电厂凝汽器内的污垢而研制的化学清洗剂QX-211,其主要组成为HEDTA、有机酸、缓蚀剂和适量的清洗助剂。该配方经动态模拟清洗试验和热电厂现场应用证明具有操作简便,清洗效果良好,对设备腐蚀小,适合不停车清洗等特点;另外,清洗废液对环境友好,易处理。[关键词]凝汽器;化学清洗;冷却水;除垢[中图分类号]TQ085+.4;TG174.42[文献标识码]A[文章编号]1005-829X(2003)01-0036-02Researchesonandapplicationofthechemicalcleaningagentprescriptioninthesteam2condenserofthermalpowerplantsOuyangZhi(FertilizerPlantofJinlingPetrochemicalCorporation,Nanjing210033,China)Abstract:Thechemicalcleaningagent,QX-211isdevelopedtocleanscaleinthesteam2condenserintheTher2malPowerPlantwithoutstoppingoperation.ItconsistsofHEDTA,organicacid,corrosioninhibitorandothercleaningassistantagent.Theprescriptionhasbeenprovedtohavethefollowingcharacteristicssuchaseasyoper2ation,highefficiency,lowcorrosionandeffectivecleaningundernormaloperationsbydynamicsimulatedcleaningexperimentandinsituapplication.Inadditionthewastewateriseasytobetreatedandnoharmtotheenviron2ment.Keywords:steam2condenser;chemicalcleaning;coolin
