本科毕业设计(论文)SLS1含油污水分离处理系统实验装置设计摘要目前,我国大部分油田采用了注水开发方式,每产生一吨原油需要注水23吨,因而水和石油生产的关系极其密切,随着我国油田开发的规模越来越大含油污水的产出量愈来愈多。而国内大部分实验设备及其研究内容都是油水分离技术,对于分离出来的污水的再处理还没有专门的实验台。尤其是对水里的乳化油,用物理方法处理还没有看到这样的系统,该方面的研究还主要集中在用化学方法破乳,机械分离法,这种方法势必造成二次污染。本文所设计的含油污水分离处理系统实验装置主要是从四个方面(气浮分离技术,文丘里管的空化射流技术,旋流技术,喷盘空化射流技术)对含油污水进行分离试验,其主要目的是为了对油田污水处理装置设计优化、动态性能测试及分析研究油田污水处理系统的设计优化及开发研究空化射流破乳技术基础研究因此,油田污水处理回注技术的研究与开发对于油田的生产具有极其重要的作用,从而对节约水资源,保护环境具有重大意义。关键词污水分离实验装置分离技术本科毕业设计(论文)ThedesignofexperimentequipmentalinseparatriontreatmentofoilywastewaterAbstractAtpresentmostofouroilfieldwaterfloodingmodeadoptedbythetoncruderequireseveryproduceinjected23tons.Thuswaterandoilproductionrelationareveryclose.Asourcountryoilfielddevelopmentscaleismoreandmorebig,oilywaterdisposingofitisgettingmoreandmore.Whereasmostofdomesticlaboratoryequipmentandresearchcontentsarewateroilseparationtechnology.Thereisntthespecialtestbenchtoseparatethesewageprocessing.Especiallyforwaterphysicaltreatments,emulsifiedfuelstillhasntseensuchsystem,thisresearchisalsomainlyconcentratedinthechemicallybrokenbreast,mechanicalisolation.Thismethodwouldcausesecondarypollution.Thispaperisdesignedbytheseparationofoilywastewatertreatmentsystemsexperimentdeviceismainlyfromfouraspectsfloatingseparationtechnology,venturitubeofcavitationjettechnology,hydrocyclonetechnology,spraythejettechnologytoPanKongseparateoilywastewater.Itsmainpurposeistotestforoilfieldsewagetreatmentplantdesignoptimization,dynamicperformancetestingandanalysis.OilfieldsewagetreatmentsystemdesignoptimizationanddevelopmentresearchCavitationjetbrokenbreasttechnologybasicresearch.Therefore,theoilfieldssewagetreatmentbacknotetechnologyresearchanddevelopmentforoilproductiontohavetheextremelyvitalrole.Thustosavethewaterresourcesandprotectstheenvironmentareofgreatsignificance..Keywordssewageseparationtestsetseparationtechnology西安石油大学本科毕业设计(论文)I目录1绪论..........................................................................................................................11.1研究的意义和目的........................................................................................11.2国内外研究状况............................................................................................11.2.1国内研究状况......................................................................................11.2.2国外发展现状......................................................................................31.2.3综上所述..........................................................................................41.3本设计的主要内容........................................................................................42油水分离实验台总体方案设计..............................................................................63气浮装置设计计算..................................................................................................73.1气浮法原理....................................................................................................73.2气浮法的设计参数........................................................................................73.3投药量计算....................................................................................................83.4药剂量............................................................................................................83.5溶气罐计算....................................................................................................83.6溶气罐的直径................................................................................................83.7理论溶解空气量............................................................................................93.8理论需气量....................................................................................................93.9溶气罐实际所需的空气量为....................................................................93.10供气量........................................................................................................103.11空压机所需压力........................................................................................103.12压力容器壳体厚度的设计计算................................................................103.13压力试验....................................................................................................113.14反应室计算................................................................................................113.15气浮分离池计算........................................................................................123.15.1气浮分离池的有效容积..................................................................123.15.2气浮分离池的有效长度...................................................................133.16溶气设备....................................................................................................133.17气浮池传动机构的设计............................................................................143.18减速器地选择............................................................................................154单管旋流子及设计计算........................................................................................174.1液液旋流器的工作原理..........................................................................
