Titanium Thiab Titanium Alloys: Corrosion Protection Thiab Performance Enhancers hauv Soda Ash Production

Soda tshauv, raws li cov khoom siv raw hauv kev lag luam tshuaj, ntsib teeb meem corrosion loj hauv nws cov txheej txheem ntau lawm. Tshwj xeeb tshaj yog nyob rau hauv qhov kev txiav txim ntawm cov pa roj los yog kua theem xov xwm, cam khwb cia hlau thiab carbon steel khoom yog feem ntau nyuaj rau tiv thaiv localized corrosion thiab crevice corrosion nres. Vim li no, kev lag luam thoob ntiaj teb soda tshauv tau tig mus rau cov khoom siv titanium kom tau raws li qhov kev sib tw no.
Titanium nyob rau hauv cov dej qab zib tshauv ntau lawm ntawm ntau yam kev siv
Nyob rau hauv kev tsim cov txheej txheem ntawm cov dej qab zib tshauv, titanium yog siv nyob rau hauv ntau qhov ntau hauv distillate gas coolers thiab condensers vim nws zoo heev corrosion kuj. Tshwj xeeb, nyias-walled titanium raj muaj lub neej ua haujlwm txog li 20 xyoo. Qhov no tsis tsuas yog txhim kho cov cua kub hloov pauv, tab sis kuj ua kom cov chaw hloov hluav taws xob ntawm cov khoom siv thiab qhov chaw hla ntawm cov hlab ntsha tsis raug txo los ntawm corrosion, uas yog qhov tseem ceeb tshwj xeeb rau cov khoom siv distillation.
Hauv Tebchaws Meskas, piv txwv li, titanium raj tau siv rau hauv cov txheej txheem soda tshauv los hloov cov cam khwb cia hlau uas yuav tsum tau hloov txhua ob xyoos. Qhov kev pib no tsis tsuas yog txuas ntxiv lub neej kev pab cuam ntawm cov cuab yeej siv, tab sis kuj tseem ua kom muaj peev xwm ntau lawm los ntawm 25%. Tsis tas li ntawd, txhawm rau txo cov nqi ntxiv, cov teb chaws txawv teb chaws kuj tau pib siv cov ntshiab titanium nqaim sawb tsim seamless nyias-walled welded hlab los hloov seamless hlab, thiab dav siv ntawm titanium phaj kub exchangers.

Tuam Tshoj tus titanium nyob rau hauv kev xyaum ntawm soda tshauv ntau lawm
Txij li thaum xyoo 1965, Tuam Tshoj kuj tau pib sim siv titanium los daws qhov teeb meem ntawm cov khoom siv corrosion hauv dej qab zib tshauv ntau lawm. Hauv kev tsim cov dej qab zib tshauv, titanium yog siv ntau yam kev siv, nrog rau cov khoom siv tseem ceeb xws li crystallization sab nraud txias, ammonia condenser nyob rau sab saum toj ntawm distillation ntauwd, ammonium chloride niam cawv rhaub, pav ca cua sov exchanger, kaus phaj kub exchanger, carbonation. ntauwd txias tube, carbon dioxide turbocompressor rotor impeller, thiab lye twj tso kua mis.
Ntawm lawv, carbonization ntauwd yog cov khoom siv tseem ceeb hauv kev tsim cov dej qab ntsev. Nyob rau hauv carbonization ntauwd, ammonia reacts nrog carbon dioxide los tsim sodium bicarbonate. Txawm li cas los xij, cov kav dej txias hauv lub tank dej txias hauv nruab nrab thiab qis qis ntawm cov pa roj carbonization ntau yog ntsib kev cuam tshuam loj heev. Yav dhau los, txawm tias sim ua ntau yam kev tiv thaiv corrosion, tsis muaj leej twg daws tau qhov teeb meem zoo. Lub neej kev pab cuam ntawm cov kav hlau cam khwb cia kuj luv heev. Txij li thaum siv titanium yeeb nkab es tsis txhob cam khwb cia hlau yeeb nkab, tsis muaj corrosion tshwm sim tau ntau xyoo, thiab cov kev pab cuam nyiaj txiag tseem ceeb.
Tsis tas li ntawd, ntau lub twj tso kua mis titanium kuj coj tau ntau yam zoo. Kev sim tau pom tias titanium twj tso kua mis tsis yog tsuas yog corrosion-resistant, hnav-resistant, tab sis kuj mus sij hawm ntev 70% mus rau 80% ntawm kev ua haujlwm siab. Qhov no tsis tsuas yog txuag hluav taws xob xwb, tab sis kuj paub txog kev ua haujlwm tsis muaj paug, yog li txuag cov ntaub ntawv thiab ntxuav ib puag ncig. Dab tsi ntxiv, titanium twj tso kua mis muaj lub neej ua haujlwm ntawm 20 txog 30 xyoo.
Nyob rau hauv cov ntsiab lus, titanium thiab titanium alloys nyob rau hauv dej qab zib tshauv ntau lawm tau pom zoo heev corrosion kuj thiab high efficiency. Nrog kev nce qib ntawm kev siv thev naus laus zis thiab kev txo nqi ntxiv, kev siv titanium hauv kev lag luam dej qab zib tshauv yuav muaj lub neej yav tom ntej.
