混合離子交換器Mixedofionexchange使用說明書OperatingInstruction一、工藝原理 Technicalprinciple本公司生產(chǎn)的混合離子交換器（簡稱混床），在脫鹽水工程中，用于二級脫鹽水的制備，被處理的水由上向下流經(jīng)按一定的比例配比裝填并混合形成的強酸、 堿樹脂層來制取成品水。均勻混合的樹脂層中，陽樹脂與陰樹脂緊密地交錯排列，每一對陽樹脂與陰樹脂顆粒似于一組復(fù)床，混床就象無數(shù)組串聯(lián)運行的復(fù)床。通過混合離子交換后進入水中的氫離子與氫氧離子會立即生成電離度很低的水分子（ H2O），很少可能形成陽離子或陰離子交換時的反離子，使交換反應(yīng)進行的十分徹底，因而能制取純度相當(dāng)高的成品水。Ourcompanyproducesthemixedionexchanger(referredtoas")ofthemixedbed,indesaltedwaterengineering,preparationforsecondarydesaltingwater,treatedwaterbythedownflowofmixedincertainproportionratioofloadingandtheformationofacid,alkali,resinlayertomanufacturethefinishedwater.Evenlymixedresinlayer,withYinYangresinresintightlystaggered,eachpairofYangYinresinparticlesandresinonasetofdoublebed,mixedbed,likecountlessgroupofdoublebedseriesoperation.Afterionexchangeinthewaterbymixinghydrogenionandhydroxideionwillimmediatelygeneratelowdegreeofionizationofwatermolecules(H2O),lesslikelytoformthecationoranionexchangeofions,maketheexchangereactionofverythoroughly,therebymakinghighpurityofthefinishedwater.混床的再生工藝較陽、陰床的再生工藝復(fù)雜，混床樹脂層失效后，需先對床中樹脂進行反洗分層，使陽樹脂與陰樹脂徹底分離，然后分別對陽、陰樹脂進行再生、清洗、恢復(fù)交換能力并均勻混合，方可繼續(xù)投入運行。Mixedbedregenerationprocessiscationexchanger、anionexchangerregenerationprocesscomplex,mixedbedresinlayerexpires,shouldfirsttobackwashingstratificationofresininthebed,makewithcationresinandanionresinseparationthoroughly,thenrespectivelyforcationresin、anionresinregeneration,cleaning,restoretheexchangecapacityandmixing,maycontinuetoputintooperation.二、技術(shù)參數(shù) Technicalparameters1. 進水Inlet water： 一級脫鹽水或RO產(chǎn)水Levelofdesalted waterorReverseosmosiswater2.出水水質(zhì)Effluentquality：<μS/cm(25℃)SiO2泄漏<20ug/l，PH接近中性SiO2leak<20ug/l,thePHnearneuter3.工作壓力Workingpressure:<4.工作溫度Workingtemperature:5-45℃運行流速Operatingvelocity:40-60m/h水反洗強度Waterbackwashingstrength:8-12m/h再生流速Regenerationvelocity:4-6m/h再生液濃度Renewableliquidconcentration:4-5%9.填料高度Packing layer height: 陽樹脂Cation 陰樹脂Anionresins201X7：500mm\1000mm三、結(jié)構(gòu)形式 Structureform設(shè)備由本體、布水裝置、集水裝置、外配管及儀表取樣裝置等組成。進水裝置為上進水、擋板布水，集水裝置為多孔板濾水帽集水；設(shè)備的本體外部配管配帶閥門并留有壓力取樣接口，便于用戶現(xiàn)場安裝和實現(xiàn)裝置正常運行。Equipment byontology, cloth water equipment, water equipment, piping andinstrument samplingdevice, etc. Feeddeviceforwater, baffle onwaterdistribution,watercatchmentdevice for porousplatefilterwatercap; Externalpipingequipmentontology matchingvalveandhadpressure samplinginterface, makingit easyfor userstothesiteinstallationandequipmentnormaloperation..設(shè)備的安裝Theinstallationoftheequipment1）安裝前檢查土建基礎(chǔ)是否按設(shè)計要求施工。1）Before the installation check whether civil engineering foundationconstructionaccordingtodesignrequirements.2）設(shè)備按設(shè)計圖紙進行就位，調(diào)整支腿墊鐵并檢查進出口法蘭的水平度和垂直度。2）Equipmentinplaceinaccordancewithdesigndrawingsandlegtoadjustshimandcheckthelevelnessoftheimportandexportoftheflangeandverticality.3）將設(shè)備和基礎(chǔ)預(yù)埋鐵板焊接固定，固定后再次校驗進出口法蘭的水平度和垂直度。3）Basedembeddediron weldingequipmentandfixed, fixed after onceagaincheckthelevelnessoftheimportandexportoftheflangeandverticality.4）將設(shè)備本體配管按編號區(qū)分后依設(shè)計圖紙進行組裝， 每段管道組裝前應(yīng)用干凈抹布對內(nèi)壁進行清潔工作，組裝后應(yīng)保持配管軸線橫平豎直，閥門朝向合理（手動閥手柄朝前，氣動閥啟動頭朝上）。4）Pipingequipmentbodyaccordingtothenumberedinaccordancewiththedesigndrawingsforassembly,aftereachsectionofthepipeassemblyapplicationcleandishclothtocleantheliningworkbefore,afterassemblyshouldmaintainthepipeaxishorizontalevenvertical,valvetowardsreasonable(manualvalvehandleforward,pneumaticvalvestartupside).5）檢查本體閥門開關(guān)靈活，有不靈活的情況及時整改。5）Checkvalvebodyflexibleswitch,timelyrectificationisnotflexible.6）設(shè)備本體配管完成后應(yīng)對閥組進行必要的支撐工作等。6）Pipingequipmentontology copewithvalvesetafter thecompletion ofnecessarysupportwork,etc.7）安裝設(shè)備上配帶的進出水壓力表、取樣閥等；進出水管道上如有流量、電導(dǎo)等探頭座應(yīng)用堵頭堵住。7）Installationofequipmentondisplayinandoutofthewaterpressuregauge,samplingvalve,etc.;Inandoutofthewaterpipechannelsuchastraffic,conductanceprobeplugseatapplicationblock.五、初次運行 Forthefirsttimetorun1）沖洗wash考慮到設(shè)備和管道連接時的電焊殘渣、管道初次投用時的表面污物，設(shè)備初次投入運行時應(yīng)進行沖洗。Considering
