Daim ntawv thov ntawm industrially ntshiab titanium hauv kev lag luam tshuaj

Titanium hlau muaj zoo heev corrosion kuj thiab mechanical zog, thiab yog dav siv nyob rau hauv ntau yam sectors. Tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv siv tshuaj, titanium tuaj yeem hloov cov hlau tsis muaj steel hlau ua cov khoom siv corrosion-resistant, uas muaj qhov tseem ceeb heev rau kev ua haujlwm ntev ntawm cov khoom siv, txo cov nqi, tiv thaiv kev ua qias tuaj thiab txhim kho kev tsim khoom. Nyob rau hauv xyoo tas los no, Tuam Tshoj cov tshuaj lom neeg kev lag luam nrog cov peev txheej ntawm titanium yog nthuav, tus nqi nce xyoo los ntawm lub xyoo, titanium tau dhau los ua cov khoom siv tshuaj hauv cov ntaub ntawv tseem ceeb corrosion-resistant. Raws li ib yam ntawm corrosion-resistant structural khoom siv nyob rau hauv tshuaj installation, titanium tau los ua ib tug zoo tagnrho khoom nyob rau hauv cov khoom siv tshuaj.
Kev lag luam chlor-alkali
Chlor-alkali kev lag luam yog ib qho tseem ceeb ntawm kev lag luam raw khoom, thiab nws cov khoom tsim thiab kev loj hlob muaj kev cuam tshuam zoo rau kev lag luam hauv lub tebchaws. Qhov no yog vim qhov corrosion kuj ntawm titanium rau chloride ions yog zoo dua li feem ntau siv stainless hlau thiab lwm yam uas tsis yog-ferrous hlau. Tam sim no, titanium yog siv dav hauv kev lag luam chlor-alkali los tsim cov hlau anode electrolyzer, ionic membrane electrolyzer, ntub chlorine txias, refined brine preheater, dechlorination ntauwd, chlorine txias scrubber ntauwd thiab lwm yam. Yav dhau los, cov khoom tseem ceeb ntawm cov khoom siv no feem ntau yog ua los ntawm cov khoom siv tsis yog xim hlau (xws li graphite, PVC, thiab lwm yam), vim tias cov khoom siv tsis yog hlau, thermal stability thiab kev ua haujlwm tsis zoo, uas ua rau cov khoom siv tsis yog hlau, thermal stability thiab kev ua haujlwm tsis zoo. Cov khoom loj thiab hnyav, kev siv hluav taws xob, lub neej ua haujlwm luv luv, thiab cuam tshuam rau qhov zoo ntawm cov khoom thiab kev ua qias tuaj ntawm ib puag ncig. Yog li ntawd, txij li xyoo 1970, Tuam Tshoj tau pib siv cov hlau anode tank thiab ionic membrane tank es tsis txhob graphite tank, titanium ntub chlorine cooler es tsis txhob graphite txias, tau ua tiav cov txiaj ntsig zoo.

Piv txwv li, daim ntawv thov ntub dej chlorine txias ua los ntawm titanium. ntsev electrolysis zus tau tej cov caustic soda yog tsim ib tug loj tus naj npawb ntawm high-temperature ntub chlorine gas, qhov kub yog feem ntau 75 ~ 95 degree, yuav tsum tau txias thiab qhuav siv. Tuam Tshoj cov ntsev electrolysis ntawm cov tshuaj chlorine, yav tas los vim cov txheej txheem txias tsis tsim nyog los yog vim yog corrosion ntawm cov khoom cua txias cuam tshuam rau cov tshuaj chlorine yield thiab zoo, tab sis kuj ua phem rau ib puag ncig. Kub-kub ntub dej chlorine corrosion-resistant titanium txias rau hauv ntau lawm, hloov lub ntsej muag ntawm chlorine ntau lawm hauv kev lag luam chlor-alkali. Titanium nyob rau hauv ib puag ncig ntawm kub ntub chlorine roj yog tsis tshua muaj corrosion-resistant, titanium nyob rau hauv chav tsev kub nyob rau hauv cov dej chlorine, corrosion tus nqi ntawm 0.{{10}}00565mm / a; ntawm 80 degree hauv dej chlorine, titanium corrosion tus nqi ntawm 0.00431mm / a; muaj 95% ntawm cov roj chlorine ntub dej, qhov corrosion ntawm titanium ntawm chav tsev kub yog 0.00096mm / a. Ntau cov chlor-alkali feem ntau siv rau titanium system ntawm cov chlorine ntub dej txias, thiab qee qhov tau siv ze li ntawm 20 xyoo, tseem tsis zoo. 20 xyoo, tseem zoo li qub.

Soda tshauv kev lag luam
Soda tshauv yog ib qho ntawm cov khoom siv tshuaj lom neeg yooj yim tshaj plaws, nws muaj feem cuam tshuam ncaj qha rau kev loj hlob ntawm kev lag luam hauv lub tebchaws. Soda tshauv tsim cov txheej txheem, cov roj nruab nrab feem ntau yog NH3 thiab CO2, cov kua nruab nrab feem ntau yog NaCl, NH4Cl, NH4HCO3 thiab Cl- concentration ntawm cov tshuaj, kev siv cov pa roj carbon steel, cam khwb cia hlau carbonation cov tshuaj tiv thaiv ntawm carbonation ntauwd tubules, kub niam cawv txias, txias, crystallization sab nraum lub txias txias thiab lwm yam khoom siv, tsis muaj corrosion-resistant, corrosion thiab to yog loj, kev pab cuam lub neej ntawm tsawg tshaj li peb xyoos. 1975-1977, Tianjin Alkali Cog, cov khoom siv tseem ceeb, cov khoom siv tseem ceeb tsis yog corrosion-resistant, corrosion thiab to yog hnyav, kev pab cuam lub neej ntawm tsawg tshaj li peb xyoos. -1977, Tianjin Soda Plant thiab Dalian Chemical Industry Company tau tsim titanium daim ntawv thov ua qauv qhia ua haujlwm, carbonization ntauwd txias tube 63 × 2mm, titanium phaj kub exchanger, titanium sab nraud txias, titanium twj, CO2 turbine compressor rotor, Ti{{13 }}Al-4V alloy impellers, thiab lwm yam. Daim ntawv thov ntawm cov nyhuv yog qhov zoo heev, uas yog kev lag luam rau kev siv titanium thev naus laus zis los ua qhov kev hloov pauv thiab kev tsim kho ntawm peb 600 tshiab,{{16} } tons ntawm cov zis txhua xyoo ntawm soda tshauv nroj tsuag tau ua lub luag haujlwm ua qauv.

Piv txwv li: ib tug soda tshauv cog distillation ntauwd nyob rau sab saum toj ntawm ammonia condenser daim ntawv thov ntawm ntshiab titanium yeeb nkab es tsis txhob cam khwb cia hlau yeeb nkab. Ammonia condenser yog cov txheej txheem tsim cov dej qab ntsev, cov ntauwd distillation yuav tawm ntawm cov khoom siv ammonia condensing, nws muaj ob lub cam khwb cia hlau txias, txhua lub thawv txoj kab uas hla 2.5m, 1.2m siab, thawj lub thawv Φ63 × 6 × 2986mm cam khwb cia hlau raj 214, tag nrho ntawm 428 ntawm ob lub thawv. Ob sab hauv thiab sab nraud ntawm cov yeeb nkab yog anticorrosive nrog thermosetting phenolic kua roj vanish, thiab qhov nruab nrab sab nraud ntawm cov yeeb nkab yog NH3, CO2, H2O vapor ntawm qhov kub ntawm li 95 degree. Sab hauv cov yeeb nkab mus NH4Cl niam cawv, thiab sab nraum cov yeeb nkab nruab nrab rau kev sib pauv cua sov. Nyob rau hauv cov xwm txheej no, cov cam khwb cia hlau yeeb nkab corrosion yog loj heev, siv ib lub xyoo uas yog ib feem ntawm cov yeeb nkab corrosion perforation, 2 xyoo tau corrosion puas yog loj, tsis siv. Txhawm rau daws qhov teeb meem ntawm kev xeb loj ntawm cov yeeb nkab hlau cam khwb cia hauv ammonia condenser, tag nrho cov cam khwb cia hlau kav yog hloov nrog TA2 titanium kav, nrog specifications ntawm Φ60 × 2 × 3010mm, thiab titanium yeeb nkab kawg yog kaw nrog O-ring roj hmab. rings nruab nrab ntawm cov yeeb nkab kawg thiab cov cam khwb cia hlau txaws daim hlau. Qhov no yog Tuam Tshoj txoj kev lag luam dej qab zib tshauv, thawj lub tshuab ua kom txias txias siv cov raj titanium ntshiab. Muab tso rau hauv kev tsim khoom thiab siv ntau tshaj li ob xyoos, tau siv cov yeeb nkab rau kev tshuaj xyuas macro, tsis muaj qhov tshwm sim corrosion, yuav tsum tau ua haujlwm ntev txog 20 xyoo lossis ntau dua, tuaj yeem txuas ntxiv 10 npaug dua li cov yeeb nkab hlau. Raws li lub titanium raj corrosion kuj, tshav kub hloov efficiency kom zoo (cam khwb cia hlau yeeb nkab nyob rau hauv 3 xyoo thaum lub sij hawm ib tug overhaul, lub tshav kub hloov efficiency ntawm lub thaum ntxov zoo, tsis zoo lub sij hawm nruab nrab, lig ntawm qhov tsis ua hauj lwm), lub raj NH4Cl niam cawv preheating. Thaum tshav kub kub rov qab, txhim kho niam cawv rau hauv lub distillation ntauwd kub, tuaj yeem txuag tau ntau chav, cov txiaj ntsig kev lag luam yog pom tseeb.
