Ua tiav kev tswj xyuas lub voj voog kev tswj hwm rau cov ntshiab titanium cua sov raj hauv kev cob qhia fermentation tas li

Lub npe: Kev tswj xyuas lub voj voog ua kom zoo rau cov ntshiab titanium cua sov tubing hauv kev cob qhia txuas ntxiv fermentation Lub sijhawm ntev - lub sij hawm ruaj khov ntawm titanium cua sov raj yog ua raws li kev saib xyuas raws sij hawm, es tsis yog qhov kev ua haujlwm dhau los - kho tsis ua haujlwm. Cov txheej txheem no faib cov kev saib xyuas mus rau hauv txhua hnub ntawm - kev tshuaj xyuas qhov chaw, kev saib xyuas txhua hli, kev kuaj xyuas peb lub hlis twg, ib nrab- kev kho dua tshiab txhua xyoo, thiab 3–5 xyoo puv - kev ntsuas lub neej. Nws qhia meej txog cov khoom tshuaj xyuas, cov qauv kev ua haujlwm, qhov kev txiav txim siab, thiab cov phiaj xwm pov tseg txawv txav rau txhua lub voj voog kom tshem tawm cov kev pheej hmoo ntawm kev puas tsuaj ua ntej thiab txuas ntxiv lub neej ntawm cov khoom siv cua sov. ## 1. Kev saib xyuas kev saib xyuas txhua hnub (5–10 feeb hauv ib lub tank, txhua qhov kev hloov pauv) ### Cov ntsiab lus ntawm Kev Tshuaj Xyuas 1. Tank kua theem interlock linkage test: Xyuas kom tseeb tias cov cua sov fais fab yuav raug kaw thaum cov kua theem poob qis rau saum lub cua sov raj, yog li tiv thaiv kom qhuav - tawm npuas corrosion {{15} ntawm qhov fpse soj ntsuam qhov chaw kua seepage, dripping, thiab dawb/grey corrosion sediment . 3. Lub raj nto yog pom los ntawm lub tank pom iav, thiab tsis muaj ib tug ntau ntawm cov pa roj carbon coking los yog tsaus pitting thaj ua rau thaj uas yog concentrated nyob rau hauv lub weld cheeb tsam. 4. Kev khiav hauj lwm ntawm lub circulation twj tso kua mis thiab aeration khoom: xyuas kom meej tias lub circulating flow thiab aeration cov qauv tsim, compatibility ntawm low flow velocity. ### Cov txheej txheem pov tseg uas yog qhov txawv txav - Cov pa taws me me: Thaum lub sij hawm kaw txhua hli, khij txoj haujlwm thiab npaj rau kev hloov pauv . - Lub sijhawm tu txhua hli hauv online rau cov pa roj carbon tuab tuab; - Kev hloov kho tam sim ntawm cov cuab yeej siv tsis yog yuav tsum tau rov ua dua -tsim kom muaj qhov ntsuas ntws nyob rau hauv qhov xwm txheej ntawm qhov tsis zoo ntawm aeration / circulation flow. ## 2. Kev saib xyuas txhua hli (kev npaj luv luv, tag nrho lub tank CIP tu, thiab kho qhov chaw passivation) ### Cov haujlwm tseem ceeb ntawm cov khoom siv 1. Ua tiav qib CIP acid-kev hloov pauv hloov pauv Kev siv tus qauv 3%–5% dilute alkali + citric acid descaling cov txheej txheem rau lub sijhawm kub thiab txias. 66. Tom qab ntawd, tuav lub tank zoo li qub rau 12-24 teev los kho cov yeeb yaj kiab thinned passive. 3. Kev tshuaj xyuas cov khoom siv flange thaum lub sij hawm disassembly Ntsuam xyuas cov laus, o, thiab deformation ntawm PTFE gaskets; tshuaj xyuas PTFE lub tsho tiv thaiv ntawm fasteners rau cov kab nrib pleb; Tam sim ntawd hloov cov khoom siv sib cais uas puas lawm. 4. Kev tshuaj xyuas qhov chaw ntog tom qab lub tank ntws Siv lub siab- teeb ci LED los tshuaj xyuas cov welds thiab txhawb qhov chaw sib cuag rau qhov chaw khawb thiab khawb thaum ntxov. Sau cov anomalous thinning txoj hauj lwm nyob rau hauv lub phab ntsa thickness los pab txhawb kev tsom xam ntawm peb lub hlis twg. ### Cov ntaub ntawv yuav tsum Sau cov dej huv huv, qhov kub thiab txias, lub sijhawm ntawm kev ntxuav, qhov ntau ntawm cov pa roj hloov pauv, thiab tej yam tsis zoo ntawm qhov chaw nyob hauv daim ntawv tu txhua hli. 3. Peb lub hlis twg uas tsis yog- kev ntsuas kev puas tsuaj (lub voj voog tshawb pom loj) ### Kev txiav txim siab ntawm phab ntsa 1.threshold Cov cim tseem ceeb: Cov ntu nruab nrab ntawm lub raj lub cev, tag nrho cov vuam cua sov- thaj chaw cuam tshuam, thaj chaw sib tiv tauj, thiab npuas- lub raj sab sauv arc. Kev nyab xeeb pib: Qhov seem phab ntsa thickness yuav tsum tshaj qhov qub thickness los ntawm 70%. Yog tias tus nqi qis dua qhov no, lub raj yuav tsum raug cim tias siab - qhov pheej hmoo thiab lub voj voog tshuaj ntsuam yuav tsum luv luv rau txhua hli . 2. Passive zaj duab xis muaj peev xwm electrochemical ntsuas Tus qauv tsim nyog muaj peev xwm ntau dua lossis sib npaug ntawm +150mV hauv kev sib piv rau cov saturated calomel electrode, nrog rau qhov sib npaug ntawm qhov sib npaug ntawm 0 V. Kev kho mob txawv txav: Ib qho tshuaj hydrogen peroxide chemical re-passivation kev kho yog pib thaum lub peev xwm tsawg dua +120mV. 3. Weld eddy tam sim no penetrant flaw detection Screen sab hauv microcracks thiab pore defects ntawm welds yuav tsum tau kho hauv zos polishing thiab lwm yam passivation. Tsis tas li ntawd, ib qho kev tsis xws luag uas ntau tshaj 0.3mm yuav tsum muaj kev nkag mus rau theem nrab. 4. Kev kuaj xyuas ntawm cov khoom siv txhawb nqa Tshawb xyuas cov hlau txhawb rau tev PTFE txheej thiab taw tes burrs uas khawb lub raj nto. Hloov cov kev txhawb nqa uas puas lawm. ## 4. Semi-Kev kho dua tshiab txhua xyoo (ntev lub tank ntev, kev tshuaj xyuas kom tiav, thiab kev kho ib feem) 1. Ua kom tiav cov khoom sib dhos ntawm cov titanium cua sov raj sib dhos Tshem lub raj ntim kom ua tiav kev tshuaj xyuas sab nraud. Siv cov tshuaj fluoride-dawb ultra- zoo polishing muab tshuaj txhuam rau polish hauv zos pitting, sib sib zog nqus caws pliav, thiab weld discoloration. 2. Ua kom tiav cov tshuaj re-passivation ntawm tag nrho cov raj Los tsim ib qho zoo sib xws, compact TiO₂ passive zaj duab xis, tso cai rau tag nrho cov cua kub lub raj kom dilute nyob rau hauv ib tug 2% hydrogen peroxide rau 7 xuab moos Ntawm cov khoom pabcuam uas raug puas tsuaj Los tshem tawm qhov tsis txaus ntseeg ntawm galvanic corrosion uas yog tshwm sim los ntawm kev laus cov ntaub ntawv cais tawm, tag nrho cov PTFE gaskets, lub tes tsho insulating bolt, thiab cov laus PTFE cov kev txhawb nqa yog hloov tsis tu ncua . 4. Rov qab rau hydraulic siab nruj Cov txheej txheem tsim nyog 5 lub sij hawm ua haujlwm siab. 30 feeb, thiab xyuas kom meej tias tsis muaj kev poob siab los yog to. Cov raj xau tau raug kho siv argon vuam thiab tom qab ntawd rov kuaj dua. 5. Kev kuaj xyuas lub zog hluav taws xob Ntsuas cov rwb thaiv tsev tiv thaiv ntawm cov xov hlau cua sov sab hauv thiab tshem tawm qhov txaus ntshai ntawm hluav taws xob xau uas yog tshwm sim los ntawm qhov ntev - lub sij hawm kev laus ntawm qhov kub thiab txias. ## 5. Kev soj ntsuam ntawm lub neej ua tiav thiab kev txiav txim siab los hloov hauv 3-5 xyoo tom ntej Ua ke nrog cov phab ntsa thickness poob, nquag ua haujlwm tsis ua haujlwm, thiab rov ua cov ntaub ntawv kho vuam, nws yog ib qho tsim nyog los txiav txim siab seb puas yuav khawb thiab hloov: ### Cov qauv rau kev hloov pauv 1. Qhov seem ntawm cov khoom siv hluav taws xob tsis zoo yuav tsum tau ua raws li cov txheej txheem ntawm cov phab ntsa 5. thickness. 2. Txawm hais tias ua tiav ntawm ntau qhov vuam pitting kho, qhov tshiab corrosion txuas ntxiv tshwm sim tom qab txhua lub voj voog txij nkawm. 3. Cov yeeb yaj kiab tsis zoo ntawm tus kheej- kho muaj peev xwm ploj tag nrho vim qhov ntev - lub sij hawm qis nto qhov peev xwm uas tshwm sim los ntawm kev rov ua dua cov khoom siv rov ua dua {{90}{90}} rov ua dua tom qab cov pa tawm ntau dua Kev hloov pauv, qhov hnyav pitting deformation ntawm flange sealing nto, thiab tsis muaj peev xwm yuav polished rau rov qab. ### Tus nqi pom zoo Tom qab 4-5 xyoos ntawm kev ua tiav, kev hloov pauv hloov pauv yog xav tau rau cov pa TA2 titanium raj. High-kawg TA1 cov cuab yeej siv tshuaj tuaj yeem txuas ntxiv mus rau 5 xyoos nrog kev kuaj xyuas nruj peb lub hlis twg. ## 6.
