"Kuv yuav tsum tau rhaub cov kua qaub rau hauv lub tank me me. Cov kev ncig sab nraud zoo li overkill. Kuv puas tuaj yeem tso lub PTFE kauj ncaj qha rau hauv lub tank? Qhov zoo thiab qhov tsis zoo ntawm qhov yooj yim txoj kev yog dab tsi, thiab kuv yuav ua li cas kom nws ua haujlwm zoo yam tsis muaj kev cuam tshuam nrog cov txheej txheem?"
Cov lus nug no tshwm sim ntau zaus hauv cov khw plating, cov chaw kuaj tshuaj, thiab cov kab ua haujlwm me me. Ntau lub tso tsheb hlau luam siv rau cov kua dej corrosive yuav tsum tau tswj qhov kub thiab txias, tab sis kev txhim kho cov khoom siv hluav taws xob sab nraud nrog cov twj tso kua mis thiab cov kav dej tuaj yeem xav tias tsis tsim nyog rau kev teeb tsa me me. Nyob rau hauv cov xwm txheej no, lub immersion heat exchanger ua los ntawm PTFE feem ntau muab ib tug tswv yim thiab kev lag luam lwm txoj.
Immersion heat exchangers sawv cev rau ib qho ntawm cov qauv yooj yim tshaj plaws ntawm cov khoom siv hluav taws xob hloov hluav taws xob. Es tsis txhob routing txheej txheem kua los ntawm ib tug sab nraud exchanger, lub tshav kub hloov lwm yam nto yog muab tso ncaj qha rau hauv lub tank uas muaj cov txheej txheem kua. Nyob rau hauv cov ntaub ntawv ntawm PTFE tsim, hloov tau fluoropolymer tubing yog tsim rau hauv coils, serpentines, los yog U-puab bundles thiab submerged nyob rau hauv lub tank. Cov cua sov lossis cua txias nruab nrab- xws li chav dej, dej kub, lossis dej txias - ntws los ntawm sab hauv ntawm lub raj, thaum lub tank dej ntws ncig sab nraud.
Kev poob ib lub kauj hauv lub tank yog qhov ua kom yuam kev qub tshaj plaws hauv phau ntawv, tab sis PTFE ua rau nws corrosion- pov thawj. Vim tias PTFE tiv taus cov kua qaub, alkalis, oxidizing cov neeg ua haujlwm, thiab ntau cov kuab tshuaj, nws tuaj yeem tiv taus cov tshuaj lom neeg uas muaj nyob hauv plating da dej, pickling tank, lossis tshuaj kho cov hlab ntsha. Qhov kev ruaj ntseg tshuaj no tso cai rau immersion exchangers ua hauj lwm ntseeg tau nyob rau hauv ib puag ncig uas metallic cua sov ntsiab yuav sai corrode.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm immersion exchangers yog lawv qhov yooj yim. Lub kaw lus yuav tsum tsis muaj lub twj tso kua mis, tsis muaj cov kav dej sab nraud, thiab tsis muaj cov khoom siv hluav taws xob ntxiv rau sab nraum lub tank. Lub exchanger txuas ncaj qha mus rau cov khoom siv cog. Chav los yog dej kub nkag mus rau ib qho kawg ntawm PTFE coil, hloov cov cua sov mus rau cov kua ib puag ncig, thiab tawm los ntawm cov kab rov qab. Rau kev siv cua txias, dej txias lossis dej txias ntauwd tuaj yeem ua haujlwm tib yam.
Qhov kev teeb tsa ncaj nraim no feem ntau txhais ua cov nqi qis dua. Piv nrog rau cov khoom siv hluav taws xob sab nraud uas xav tau cov twj tso kua mis, cov li qub, thiab tswj cov kav dej, lub immersion coil muaj cov khoom siv tsawg dua thiab cov khoom siv tsawg dua. Rau cov tso tsheb hlau luam me lossis cov haujlwm ua kom sov tsis tu ncua, cov peev nyiaj txo qis tuaj yeem yog qhov txiaj ntsig tseem ceeb.
Lwm qhov txiaj ntsig yog qhov ncaj qha ntawm cov txheej txheem hloov hluav taws xob. Thaum tshav kub kub txav los ntawm cov dej siv hluav taws xob los ntawm PTFE tubing phab ntsa ncaj qha mus rau hauv cov kua tank. Tsis muaj qhov nruab nrab ntawm cov cua sov hloov mus los lossis cov kua dej ntxiv. Raws li qhov tshwm sim, lub zog thermal ncav cuag cov txheej txheem dej nrog kev ncua me ntsis, uas tuaj yeem pab tau hauv kev ua haujlwm batch uas cov ntsiab lus tank yuav tsum tau rhuab lossis txias sai.
Txawm hais tias nws txoj kev yooj yim, qhov ua tau zoo ntawm kev sib hloov pauv yog nyob ntawm qhov tsim ntawm lub kauj nws tus kheej. Tus nqi ntawm cov cua sov uas tuaj yeem hloov mus rau hauv lossis tawm ntawm lub tank yog nyob ntawm tag nrho cov cheeb tsam ntawm lub raj xa mus rau cov kua. Cov kws kho tsheb yog li tsim cov PTFE tubing rau hauv kev teeb tsa uas ua kom thaj chaw loj tshaj plaws nyob rau hauv qhov chaw muaj tank. Cov qauv serpentine, kauv coils, thiab U- zoo li cov pob khoom muaj ntau vim tias lawv tso cai rau cov raj ntev ntev kom haum rau hauv qhov ntim me me.
Qhov chaw ntawm lub kauj hauv lub tank yog qhov tseem ceeb sib npaug. Qhov chaw yog txhua yam - ze rau qhov chaw ua haujlwm dhau lawm thiab muaj kev pheej hmoo ntawm cov cua sov hauv zos lossis qhov kub tsis sib xws. Hauv plating tank, piv txwv li, coils yuav tsum nyob deb ntawm racks lossis cov khoom ua tiav. Qhov no tiv thaiv kev cuam tshuam nrog kev ua haujlwm plating thiab txo qhov muaj peev xwm ntawm cov chaw kub kub hauv zos uas tuaj yeem cuam tshuam qhov zoo ntawm deposition.
Lub kauj yuav tsum tau nyob rau hauv ib cheeb tsam uas lub tank kua circulates dawb do. Thaum tshav kub kub hloov mus txhim kho thaum cov kua dej tshiab tsis tu ncua ntws thoob plaws lub exchanger nto. Hauv qee lub tso tsheb hlau luam, cov khoom siv hluav taws xob uas tsim los ntawm qhov sib txawv ntawm qhov kub thiab txias tuaj yeem ua kom txaus txaus. Hauv lwm tus, cov neeg kho tshuab agitation lossis cua sparging pab sib tov lub da dej thiab faib cov cua sov sib npaug thoob plaws hauv lub tank.
Vim tias PTFE tubing yog qhov hloov tau yooj yim piv nrog cov kav hlau, kev txhawb nqa txhua yam yuav tsum tau ua tib zoo xav thaum lub sijhawm teeb tsa. Cov coils tsis txhawb nqa tuaj yeem txav los yog sag dhau sijhawm, tshwj xeeb tshaj yog thaum ntim cov kua dej kub. Qee qhov xwm txheej, buoyancy rog tuaj yeem ua rau qee qhov ntawm lub kauj vab yog tias tsis muaj kev thauj mus los zoo. Kev them nyiaj yug brackets, thav duab, lossis cov ntsiab lus txuas yog yog li siv los ua kom ruaj khov rau hauv qhov chaw thiab tswj nws cov geometry.
Kev sib txuas ntawm cov kauj thiab cov khoom siv hluav taws xob kuj yuav tsum tau saib xyuas. Flexible hoses feem ntau yog siv los txuas cov chav dej, dej kub, lossis cov kav dej txias rau PTFE tubing. Cov kev sib txuas no haum rau thermal expansion thiab txo cov neeg kho tshuab kev nyuaj siab ntawm lub kauj. Tso cai rau lub exchanger nthuav me ntsis raws li qhov kub hloov pauv yuav pab tiv thaiv kev qaug zog lossis deformation nyob rau lub sijhawm ua haujlwm ntev.
Kev saib xyuas yuav tsum tsis txhob saib xyuas. Immersion exchangers khiav lag luam ncaj qha nyob rau hauv cov txheej txheem ib puag ncig, uas txhais tau hais tias lawv yuav raug rau scale, sludge, los yog lwm yam deposits nyob rau hauv lub tank kua. Nyob rau tib lub sijhawm, cov deposits no tuaj yeem khaws cia rau sab nraud ntawm cov tubing thiab txo cov cua sov ua haujlwm.
Hmoov zoo, PTFE qhov tsis yog - cov yam ntxwv stick yuav txwv qhov adhesion ntawm ntau hom fouling. Thaum tu tsim nyog, lub kauj feem ntau tuaj yeem raug tshem tawm ntawm lub tank los yog yaug rau hauv qhov chaw nrog cov tshuaj ntxuav kom tsim nyog. Tsim kev teeb tsa kom lub exchanger tuaj yeem nqa tawm ntawm lub tank yam tsis muaj qhov loj disassembly simplifies cov txheej txheem txij nkawm.
Piv nrog rau cov khoom siv hluav taws xob sab nraud, kev tsim cov immersion koom nrog qee yam kev lag luam tawm - tawm. Cov txheej txheem sab nraud muab kev tswj xyuas ntau dua ntawm cov dej ntws thiab feem ntau ua tiav qhov sib txawv ntawm qhov kub thiab txias vim tias cov txheej txheem ua kua tau nquag nqus los ntawm kev sib hloov. Lawv kuj tso cai rau qhov chaw hloov hluav taws xob loj dua los nruab rau sab nraum lub tank.
Immersion exchangers, ntawm qhov tod tes, yog qhov zoo tshaj plaws rau cov tso tsheb hlau luam me lossis cov txheej txheem batch uas yooj yim thiab tus nqi qis yog qhov tseem ceeb. Lawv ua haujlwm zoo tshwj xeeb yog tias lub tank muaj qhov chaw sab hauv txaus kom haum rau lub kauj yam tsis muaj kev cuam tshuam nrog cov khoom siv lossis cov khoom tuav.
Nyob rau hauv ntau yam kev siv, immersion PTFE tshav kub exchangers ntaus ib tug zoo tshuav nyiaj li cas ntawm simplicity thiab kev ua tau zoo. Lawv cov corrosion kuj ua rau lawv sib xws nrog cov tshuaj aggressively, thaum lawv ncaj qha installation txo cov khoom complexity.
Thaum tsim thiab ua kom zoo, cov khoom sib pauv no muab cov cua sov zoo lossis cua txias ncaj qha rau hauv lub tank ib puag ncig. Qhov tseem ceeb yog nyob rau hauv kev xav coil tsim, ruaj ntseg installation, thiab xyuas kom meej txaus cov kua txav nyob ib ncig ntawm lub tshav kub hloov chaw. Cov ntsiab cai no pab ua kom muaj kev tswj xyuas qhov kub thiab txias thiab lub neej ntev ntawm cov cuab yeej siv - kev txiav txim siab uas siv rau txhua yam khoom siv hauv lub tank txheej txheem.
