Ntau qhov chaw tsim khoom suav nrog zaub mov- qib tsis tu ncua- cov dej kub, preheating units rau qis- dej khib nyiab, cua sov circuits rau cov txheej txheem tshuaj corrosive me me dej thiab cov cuab yeej siv ntxhua khaub ncaws tso siab rau cov cua sov ua kom sov ua haujlwm nyob rau hauv ib puag ncig zoo aqueous. Cov kua dej no tsuas yog muaj me me ntawm cov organic acids tsis muaj zog, tshem tawm cov teeb meem thiab qis - qib chloride ions thiab tsis ua rau muaj kev pheej hmoo corrosion hnyav. Cov txheej txheem carbon steel cua sov tubs raug kev xeb thiab phab ntsa poob nyob rau hauv ntev - lub sij hawm ua kua. Lub caij no, siab -spec tiv thaiv- kev xaiv corrosion xws li ntshiab titanium rhaub thiab tag nrho PFA cov cua sov muab cov kev ua tau zoo tshaj plaws thiab thawb cov phiaj xwm nyiaj txiag tsis tsim nyog. Kev txhawb zog nrog molybdenum thiab tsim nrog ultra{11}}tsawg carbon thev naus laus zis, 316L stainless hlau tsim kev cog lus rau tus kheej- kho oxide txheej hauv cov dej tsis muaj zog, ua tiav qhov dej zoo{14}} sib npaug ntawm kev tiv thaiv corrosion, txhua yam muaj zog thiab kev sib tw nqi. Tsab ntawv xov xwm no txheeb xyuas nws cov khoom zoo, kev hloov pauv ntawm thaj chaw, siv tau thiab cov txheej txheem kev xaiv engineering, thiab tsim kom muaj ntau qhov sib piv - cov lus sib piv ntawm plaub cov khoom siv cua sov uas siv nyob rau hauv qis -corrosion aqueous kev khiav hauj lwm ib puag ncig.
1. Cov txiaj ntsig tseem ceeb thiab cov yam ntxwv ua haujlwm
Piv nrog rau 304 stainless hlau li niaj zaus, 316L stainless hlau ntxiv molybdenum thiab txais ultra- carbon muaj pes tsawg leeg, prominently lifting nws tsis kam mus rau chloride pitting thiab crevice corrosion. Cov yeeb yaj kiab tiv thaiv ntawm nws qhov chaw tseem nyob ruaj khov thaum lub sij hawm ntev - lub sij hawm me me dej ncig thiab tuaj yeem kho nws tus kheej hauv cov dej ntub dej, tiv thaiv kom tsis txhob ntws tawm los ntawm corrosive. Cov khoom no muaj cov yam ntxwv zoo tag nrho cov khoom siv kho tshuab, siab tawv thiab ua haujlwm zoo rau kev vibration thiab cuam tshuam. Nws txhawb kev txhim kho yooj yim xws li xov txuas thiab flange mounting. Raws li cov dej tsis tu ncua scouring thiab cov cuab yeej kev co ntawm qhov chaw, nws tswj kev ua haujlwm zoo dua qub dua li cov cua sov quartz tsis yooj yim thiab cov cua sov fluoroplastic tsis yooj yim. Cov thermal conductivity zoo ib yam ua kom khov kho, txawm tias cov khoom siv cua sov thaum lub sij hawm ntev -khiav kev lag luam circulating dej cua sov.

3. Cov khoom txwv thiab txwv tsis pub ua haujlwm
316L stainless hlau immersion rhaub yog tsim tshwj xeeb rauruaj khov, ib leeg -cov khoom, cov dej tsis muaj zog corrosive- raws li cov kua. Lawv tsis tuaj yeem tiv taus ib puag ncig uas muaj salinity siab, concentrated acid los yog concentrated alkali, thiab tsis txhawb kev rov ua haujlwm ntawm cov kua qaub thiab alkali. Thaum raug rau siab -concentration corrosive tshuaj, txheej txheej passivation saum npoo yuav raug rhuav tshem tag nrho, ua rau cov phab ntsa txuas ntxiv thinning, pitting kab noj hniav thiab thaum kawg lub cua sov burnout thiab to. Tsis tas li ntawd, siab -ceev khiav nqa cov khoom abrasive nyuaj yuav ua rau kom qhov chaw puas thiab ua tsis tiav ntxov. Rau qhov nyuaj nyuaj corrosive ib puag ncig, engineers yuav tsum xaiv cov ntshiab titanium heaters los yog tag nrho encapsulated PFA heaters li hloov.
4. Kev Xaiv Engineering thiab Cov Lus Nug
Rau lub Hoobkas ncig dej kub, preheating ntawm qis - dej khib nyiab thiab khoom noj khoom haus - qib txheej txheem dej cua sov, 316L stainless hlau immersion rhaub muab ib qho kev cia siab thiab tus nqi -kev siv hluav taws xob zoo thoob ntiaj teb. Hauv kev npaj engineering, cov neeg tsim qauv yuav tsum tau txais 316L cov cua sov tshwj xeeb rau kev ua haujlwm nrog cov xov xwm me me kom tsis txhob muaj cov nqi yuav khoom ntau dhau los ntawm cov khoom siv overgraded. Tsim nyog sib piv ntawm cov khoom siv thiab qhov nruab nrab corrosivity pab txiav cov cuab yeej tsis ua haujlwm, ua kom lub neej ntev thiab txhawb nqa tag nrho cov nyiaj txiag rov qab ntawm cov tshuab thermal.
