Lub Phaj Ua li cas -Hom PTFE Thaum tshav kub kub Exchanger piv rau lwm cov qauv tsim rau qhov chaw me me?

"Cov chav huv huv tsis loj, tab sis koj yuav tsum tau ua kom sov me me ntawm cov dej ntshiab heev. Lub plhaub loj loj thiab lub raj xa hluav taws xob yuav tsis haum. Phaj cua sov exchangers paub tias yog compact, tab sis lawv puas muaj nyob rau hauv PTFE? Lawv ua li cas piv nrog rau lwm yam PTFE designs nyob rau hauv cov nqe lus ntawm tshav kub kis tau tus mob thiab siab poob?

Qhov chaw yog nyob ntawm tus nqi ntawm ntau yam ntawm cov nroj tsuag niaj hnub no, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas cov khoom siv yuav tsum tau nyob hauv chav huv, chav kuaj lossis cov kab ntau lawm. Cov khoom siv hluav taws xob tiv thaiv hluav taws xob hloov hluav taws xob feem ntau xav tau rau kev tuav cov corrosive los yog purity heev - cov kua rhiab heev siv hauv cov khoom siv hluav taws xob, kev ua tshuaj, thiab qee cov ntawv thov zaub mov. Nyob rau hauv cov xwm txheej zoo li no, ib qho kev daws teeb meem yog kev siv PTFE phaj kub exchangers uas muaj corrosion kuj thiab tsim me me heev.

Phaj kub exchangers txawv heev los ntawm cov classic plhaub - thiab - raj tsim uas dominates ntau yam kev lag luam. Lub phaj tsim yog ib pawg ntawm nyias daim hlau stacked nyob rau hauv parallel, es tsis txhob bundles ntawm hlab nyob rau hauv ib lub plhaub. Cov phaj ntawm PTFE phaj exchangers yog tsim los ntawm cov ntaub ntawv fluoropolymer resistant rau cov tshuaj hnyav. Txhua lub phaj yog tsim nrog corrugations los yog cov qauv nto uas tsim kom muaj cov dej ntws mus.

Cov paib, thaum sib xyaw ua ke, tsim cov kev sib hloov rau ob qho dej sib txawv, ib qho rau cov txheej txheem ntws thiab ib qho rau cov cua sov lossis cua txias nruab nrab. Cov kua dej ntws los ntawm cov kab nyob ze thiab cov cua sov tau xa mus los ntawm cov PTFE nyias- phaj saum npoo. Txij li qhov sib nrug ntawm cov phiaj yog nqaim thiab cov qauv yog txheej, qhov loj ntawm qhov kub hloov pauv tuaj yeem ntim rau hauv qhov ntim me me.

Qhov kev tsim no muab ib qho txiaj ntsig zoo ntawm cov phaj sib pauv, uas yog, thaj chaw loj heev uas cuam tshuam rau lub cev loj ntawm cov khoom siv. Nyob rau hauv ib qho xwm txheej thaum txhua square taw suav, lub phaj exchanger muab koj siab tshaj plaws kev sib kis ntawm tshav kub nyob rau hauv qhov tsawg tshaj plaws. Qhov kev cog lus no yog qhov tseem ceeb ntawm kev tsim vaj tsev nyob rau hauv cov chaw xws li cov khoom siv hluav taws xob semiconductor los yog cov chaw muag tshuaj uas thaj chaw hauv pem teb yog kim lossis nruj nruj.

Cov qauv corrugated ntawm daim hlau kuj tseem ceeb heev rau kev ua haujlwm kub hloov pauv. Cov corrugations ua rau muaj kev kub ntxhov txawm nyob rau hauv tus nqi qis qis raws li cov kua nkag los ntawm cov kab me me ntawm cov phiaj. Nyob rau hauv cov ntaub ntawv ntawm turbulent flow, lub thermally tsim ciam txheej nyob rau hauv lub tshav kub hloov lwm lub tsev yog cuam tshuam muab ib tug ntau npaum li cas ntawm tshav kub hloov ntawm cov kua.

Qhov no turbulence ua rau cov tsis muaj zog tshav kub conductivity ntawm PTFE txheeb ze rau hlau. Txawm hais tias cov ntaub ntawv fluoropolymer tsis zoo li tus neeg xyuas pib ntawm cov cua sov zoo li cov hlau tsis muaj steel, PTFE phaj exchangers muaj qhov tsim nyog hloov hluav taws xob coefficients vim yog cov phab ntsa nyias nyias thiab txhim kho cov kua dej sib xyaw. Qhov kev ua tau zoo tshaj qhov txaus rau ntau daim ntawv thov uas xav tau cov kua dej huv thiab nruab nrab cov nqi ntws.

Lwm qhov zoo ntawm cov phaj exchangers yog lawv cov khoom sib piv cov kua dej tsawg tsawg. Cov channel sab hauv yog nqaim thiab tag nrho cov ntim sab hauv yog me me piv rau ntau lwm hom kev sib pauv. Cov cuab yeej no tuaj yeem pab tau tshwj xeeb tshaj yog thaum cov txheej txheem ua kua dej yog kim, txaus ntshai lossis ntshiab heev. Piv txwv li, hauv cov tshuab dej ultrapure rau kev tsim cov khoom siv hluav taws xob, cov dej tuav tsawg dua - txo qis kev pheej hmoo kis kab mob thiab ua rau lub cev yaug yooj yim dua thaum kho.

Kev saib xyuas kev nkag yog ib qho ntxiv, tshwj xeeb tshaj yog nrog gasketed phaj tsim. Cov phaj hauv cov khoom siv hluav taws xob no tau tuav ua ke nrog cov gaskets uas kaw cov kab sib txawv. Yog hais tias fouling los yog kis kab mob tshwm sim, lub tsev yuav qhib tau thiab ib tug neeg daim hlau rho tawm los ntxuav los yog tshuaj xyuas. Cov qauv modular no tso cai rau cov kws kho mob tuaj koom rau cov teeb meem tshwj xeeb yam tsis tas yuav hloov pauv tag nrho.

Txawm li cas los xij, nyob rau hauv cov xwm txheej corrosive, gasket compatibility yuav tsum tau ua tib zoo soj ntsuam. PTFE daim hlau yog tshuaj resistant tab sis cov ntaub ntawv sealing kuj yuav tsum tau sib xws nrog cov txheej txheem ib puag ncig. Hauv qee qhov kev siv, welded los yog sib koom ua ke phaj hloov pauv gasketed versions. Cov chav no tsis xav tau gasket compatibility tab sis tsis qhib rau kev tshuaj xyuas yog li lawv siv cov txheej txheem tshuaj ntxuav.

Kev txwv siab thiab qhov kub thiab txias kuj tseem ceeb rau kev txiav txim siab thaum txiav txim siab phaj-hom exchangers. Phaj exchangers feem ntau muaj qhov ntsuas qis dua li lub plhaub - thiab - cov khoom siv raj, vim tias cov phaj nyias nyias tau txais kev txhawb nqa feem ntau los ntawm kev tsim cov ncej. Tus tsim yog tsim rau nruab nrab siab thiab kub nyob rau hauv lub khiav hauj lwm ntau yam ntawm PTFE, feem ntau mus txog 150-200 degree. Thaum muaj kev kub ntxhov ntau dua yuav tsum muaj cov ntaub ntawv hloov pauv zoo dua.

Tus cwj pwm fouling kuj txawv rau cov phaj exchangers thiab lwm hom. Lub turbulence tsim los ntawm corrugated raws yuav txo cov tsub zuj zuj ntawm deposits ntawm tshav kub hloov chaw. Cov kab ke uas muaj cov kua dej huv si muaj cov fouling tsawg heev. Qhov twg muaj cov deposits tshwm sim, muaj peev xwm tshem tawm thiab ntxuav ib tug neeg daim hlau yooj yim txij nkawm txheej txheem nyob rau hauv gasketed li.

Xws li cov khoom ua rau PTFE phaj kub exchangers tshwj xeeb tshaj yog haum rau cov lag luam uas huv thiab corrosion kuj tseem ceeb heev. Lawv feem ntau yog siv los ua kom sov lossis txias ultra- cov dej ntshiab txuas nrog cov txheej txheem ntub dej hauv cov chaw tsim khoom semiconductor. Cov khoom sib piv sib piv yog siv hauv dej- rau- cov voj voog txhaj tshuaj lossis cov tshuaj npaj tshuaj thiab feem ntau pom nyob rau hauv cov chaw tsim tshuaj uas tsim kev huv huv thiab cov kua dej tsawg kawg nkaus - yog qhov tseem ceeb heev. Hauv qee qhov kev lag luam ua zaub mov, uas siv cov tshuaj tua kab mob hnyav, me me, tshuaj lom neeg -cov tshuaj tiv thaiv kab mob kuj tseem siv.

Plate designs muaj qhov zoo sib xws ntawm lub plhaub - thiab - raj PTFE exchangers nyob rau hauv compactness thiab tshav kub hloov efficiency. Plhaub-thiab-tube units tseem zoo dua rau cov ntawv thov siab, cov nqi ntws siab lossis cov kev pabcuam cuam tshuam nrog kev sib kis. Ntau lub siab ntev ntawm kev ua haujlwm nyuaj vim lawv cov qauv siv tshuab ruaj khov thiab cov dej ntws loj dua.

Lwm txoj hauv kev yuav yog hom PTFE immersion exchangers, tab sis cov no yog rau lub hom phiaj sib txawv. Cov chav no feem ntau yog ntsia ncaj qha rau hauv cov tso tsheb hlau luam lossis cov da dej thiab nyob ntawm seb lub ntuj convection lossis mechanical agitation rau cua sov. Immersion exchangers yog qhov yooj yim thiab siv tau rau lub tank cua sov lossis cua txias, tab sis tsis ua haujlwm zoo lossis compact li cov khoom siv phaj rau hauv - cov txheej txheem kwj.

Nyob rau hauv lub sij hawm ntev lub phaj - hom PTFE tshav kub exchanger muaj ib tug muaj txiaj ntsim niche nyob rau hauv lub ntiaj teb no ntau dua ntawm cov khoom cua kub hloov lwm lub tsev. PTFE daim hlau muab kev tiv thaiv corrosion rau cov hneev taw me me rau cov phaj sib pauv, ua kom cov kws ua haujlwm los daws cov teeb meem thermal hauv qhov chaw uas cov cuab yeej loj yuav tsis haum.

Thaum ua raws li cov txheej txheem, tshwj xeeb tshaj yog tus nqi ntws, siab thiab tshuaj lom neeg sib raug zoo, cov kev sib pauv no ua kom muaj txiaj ntsig zoo, txhim khu kev qha hauv qhov chaw - txwv kev teeb tsa. Lawv cov hneev taw me me, kev ua haujlwm kub hloov pauv tau zoo thiab cov kev saib xyuas yooj yim kuj qiv lawv zoo rau cov kev xav tau ntawm kev lag luam huv si qhov twg corrosion kuj thiab qhov chaw ua haujlwm yog qhov tseem ceeb tsim qauv.

Thaum muaj cov tshuaj hnyav hnyav thiab qhov chaw nruj nruj, phaj - hom PTFE cov khoom siv hluav taws xob feem ntau dhau los ua qhov kev xaiv. Lawv qhov kev ua tau zoo qhia tau hais tias yuav ua li cas ceev faj tus qauv yuav kov yeej cov khoom siv txwv thiab ua kom muaj kev tswj xyuas qhov kub zoo hauv qhov chaw tshwj xeeb hauv kev lag luam.
