火电厂脱硫废水曝气装置优化改造与效果分析董吉柱✉(深能合和电力(河源)有限公司,广东河源,517000)摘要:[目的]曝气风机是火电厂脱硫废水预处理系统中的重要设备,一般用作为曝气池内部曝气装置提供气源,因此曝气风机使用的可靠性直接影响着脱硫废水预处理系统运行的稳定性。[方法]主要介绍脱硫废水预处理特性和工艺流程,并以实际案例对目前曝气装置中存在的通病进行深入剖析,最终确定采取合理布设顶进式搅拌器代替曝气装置的技术方案路线。[结果]通过对改造前后的脱硫废水指标、污泥沉积情况和经济性进行分析,表明该技术改造不仅成功的解决了曝气池内污泥频繁沉积问题,运维费用比原曝气装置降低了85.29%,厂用电费用降低了52.78%,而且提高了脱硫废水预处理系统运行的稳定性。[结论]对于解决同类型脱硫废水曝气装置存在的问题具有较高的参考价值。关键词:曝气风机;曝气池;脱硫废水;顶进式搅拌器;污泥沉积中图分类号:TM611;X703文献标志码:A文章编号:2095-8676(2023)S1-0074-07开放科学(资源服务)二维码:OptimizationandEffectAnalysisofDesulfurizationWastewaterAerationDeviceinThermalPowerPlantDONGJizhu✉(ShennengHeheElectricPower(Heyuan)Co.,Ltd,Heyuan517000,Guangdong,China)Abstract:[Introduction]Aerationfanisanimportantequipmentinthedesulfurizationwastewaterpretreatmentsystemofthermalpowerplant.Itisgenerallyusedasthegassupplysourcefortheaerationdeviceintheaerationtank.Therefore,thereliabilityoftheaerationfandirectlyaffectsthestabilityofthedesulfurizationwastewaterpretreatmentsystem.[Methods]Thispapermainlydescribedthecharacteristicsandprocessofdesulfurizationwastewaterpretreatment,thoroughlyanalyzedthecommonproblemsexistingintheaerationdevicewithapracticalcase,andfinallydeterminedthetechnicalschemeofreplacingtheaerationdevicewithareasonablyarrangedtopentryagitator.[Result]Byanalyzingthedesulfurizationwastewaterindex,sludgedepositionandeconomicalefficiencybeforeandafterthetransformation,itshowsthatthetechnicaltransformationnotonlycansuccessfullysolvetheproblemoffrequentsludgedepositionintheaerationtank,reducetheoperationandmaintenancecostsby85.29%comparedwiththeoriginalaerationdeviceandbringdowntheauxiliarypowercostby52.78...
