隔油池的设计.doc

隔油池的设计——处理5万吨/天的炼油废水摘要炼油废水一般都是以含油废水为主，隔油是处理含油废水的必要步骤，隔油的设备很多，可以根据含油废水的性质不同选择不同的隔油设备，而隔油池是处理炼油厂排放的含油废水的主要构筑物。隔油池是分离废水中的浮油及泥沙的构筑物，它是利用油于水之间的密度差异进行油水分离的。隔油池也是用上浮方法去除废水中相对密度小于1的浮油的构筑物。隔油池的一般分为平流式隔油池，斜管斜板式隔油池(平行板式隔油池和波纹板式隔油池)，吸油插板式隔油池，下水道式隔油池，排洪沟式隔油池等。处理炼油废水常应用平流式隔油池和斜管斜板式隔油池，其中平流式隔油池是处理炼油厂废水的标准设备，它是美国石油协会的API制定的定定性标准而设计的。平流式隔油池相对于其他类型的隔油池具有结构简单，运行管理方便，除油效果稳定等特点。在本次设计通过比较依然选用平流式隔油池处理流量为5万吨/天的炼油废水。通过油滴上浮速度法计算得出平流式隔油池的构筑尺寸，画出结构示意图。关键词：炼油废水，平流式隔油池，油水分离AbstractTheoilrefiningwastewaterisamainsourceofoilywater,separatingoilisnecessarystepoftreatingtheoilywater,therearealotofequipmentsforseparatingoil,wecanchoosedifferentequipmentsforseparatingoilaccordingtothepropertyofoilywater,andtheoilseparatorpondisthemainconstructtohandletheoilywaterofoilrefinery.oilseparatorpondistheconstructtoseparatethefloatoilandsediments,itmakeuseofdensitydifferenceofoilandwaterofcarryontheoil-waterseparation.Oilseparatorpondisalsotheconstruct，inwhichfloatoilthatitsdensitywassmallerthan1wasseparatedwiththemethodoffloatation.Therearelotsofkindsofoilseparatorponds,amongthem,theevenflowtypeisthemostfamiliartoseparatetheoilpond,inclinedtakecareoftheinclinedplanktypetoseparatetheoilpond.(Theparallelplanktypetoseparatetheoilpondandripplesplanktypestoseparatetheoilpond).Theprocessingoilrefiningwastewateroftenappliedthesetwokindsofseparatetheoilponds.Theevenflowtypeseparatetheoilpondisstandardequipmentthathandlestheoilrefinerywastewater,itisthecertainlysettleoftheAPIestablishmentsexstandardbutdesignsofAmericanPetroleumInstituteof.Withinclinedtakecareoftheinclinedplanktypetoseparatetheoilpondtocomparetheevenflowtypetoseparatetheoilpondtohavethestructureinbrief,circulatemanagementconvenience,supportinbrief,stabilizeetc.inadditiontotheoilresultadvantages.Theevenflowtypeseparatetheoilpondinadditiontotheoilefficiencyisgenerallyabove60%.Currently,separatetheoilpondapplicationtocomparewiththeevenflowtypeinthedomesticeachoilrefiningofbigoilrefineryliquidwasteprocessingcraftextensively.Passtochoosemoreandstilltooilse
