Hauv lub tshuab nqus tsev ntsev, cov khoom siv raw yog brine, uas muaj cov xov xwm corrosive ntau. Nws cov khoom tseem ceeb, xws li brine preheater, rhaub, thiab evaporation tank, raug rau siab concentration brine rau lub sij hawm ntev ntawm kub kub thiab yog tas li cuam tshuam los ntawm ntsev xuab zeb. Raws li qhov xwm txheej no, cov cuab yeej siv yuav tsum ua haujlwm ib txwm siv sijhawm ntev, thiab kev tiv thaiv corrosion yog qhov teeb meem tseem ceeb, Rau kev tiv thaiv corrosion, koj puas xav txog?Gr7 Titanium phaj?
Muaj ntau qhov laj thawj rau corrosion, ntawm cov uas muaj O2, qhov kub thiab txias, Cl - thiab cov ntsev ntsev yog qhov tseem ceeb. Txoj kev siv los tiv thaiv corrosion feem ntau suav nrog deoxidation, pH hloov kho, kev tiv thaiv electrochemical, txheej tiv thaiv, kev siv cov khoom siv los tiv thaiv corrosion, thiab lwm yam.titanium thiab titanium alloyhauv lub tshuab nqus tsev ntsev ua yog ib qho ntawm lawv.
Preheater:
Lub brine yuav tsum tau preheated ua ntej nkag mus rau lub rhaub kom txuag hluav taws xob. Yav dhau los, lub preheater feem ntau siv tubular tshav kub exchanger. Cov khoom ntawm lub tshav kub exchanger tube yog ua los ntawm carbon steel, uas yog heev yooj yim mus thaiv thiab corroded. Lub raj xa hluav taws xob feem ntau yuav tsum tau hloov thiab nres rau kev txij nkawm, uas ua rau muaj qhov tsis yooj yim rau kev tsim khoom. Kuj tseem muaj cov raj tooj liab liab preheaters, qhov corrosion tseem tshwm sim, kev pab cuam lub neej txuas ntxiv mus rau 1 xyoo, tab sis nws tseem luv heev, thiab tus nqi ntawm lub raj tooj liab liab yog siab heev.
Kom txog rau thaum qhov tshwm sim ntawmGr7 Titanium phaj kub exchanger. Lub tshav kub exchanger nto ntawm lub phaj kub exchanger yog lub phaj. Txawm hais tias nws lub zog tsis muaj zog npaum li cov tubular cua kub exchanger, nws muaj qhov zoo ntawm cov cua kub hloov pauv, cov khoom siv tsawg dua, lub teeb yuag, yooj yim txij nkawm, thiab nws lub neej kev pabcuam tuaj yeem ncav cuag 15 xyoo. Cov ntshiab titanium phaj kub exchanger siv nyob rau hauv lub Zigong Ziliujing ntsev nroj tsuag tau siv txij li thaum 1994. Lub titanium phaj tseem ci li tshiab thiab yeej tsis tau hloov, nrog pom tseeb nyiaj txiag txiaj.

Cua sov:
Txij li thaum lub tshav kub hloov pauv ntawm lub tshuab cua sov yog nyob ze rau ntawm daim ntawv raj, kev saib xyuas thiab kev kho dua tshiab yog siv sijhawm ntev, thiab tag nrho cov cua sov raj yuav tsum tau hloov ib xyoos ib zaug. Qhov kub ntawm qhov cuam tshuam II thiab cov nyhuv III yog qis dua, thiab cov cua kub cua sov tuaj yeem siv tau li ntawm 2 xyoos. Qhov tsawg kawg nkaus kub ntawm cov nyhuv IV tsuas yog siv tau rau 4 xyoo thiab yuav tsum tau hloov. Thaum lub sij hawm overhaul, lub shutdown ncua sij hawm ntau lawm, txo ntau lawm, cuam tshuam rau ntau lawm, thiab cov txij nkawm tus nqi siab (qee manufacturers siv liab tooj liab nyob rau hauv lub cua sov chamber, qhov teeb meem no tau zoo dua, tab sis cov kev pab cuam lub neej kuv tsuas yog 3-5. xyoo). Nyob rau hauv saib ntawm cov yam ntxwv ntawm titanium, yogGr7 Titanium phajyog siv nyob rau hauv cov cua sov, qhov teeb meem yuav zoo heev.
