Thin-walled Titanium Tubing yog dab tsi?

Titanium coil daim ntawv thov tsis tuaj yeem siv rau hauv cov tshuaj chlorine qhuav. Titanium nyob rau hauv qhuav chlorine, txawm nyob rau hauv qhov kub thiab txias hauv qab no {{0}}} degree, undergoes ib tug muaj zog tshuaj tiv thaiv, tsim titanium tetrachloride, uas yog soj ntsuam raws li titanium dichloride thiab txawm burns. Titanium tsuas tuaj yeem txuas txhim khu kev qha ruaj ntseg hauv nws thaum cov dej ntsiab lus ntawm chlorine tshaj 0.5%.

Nyob rau hauv cov txheej txheem tsim kom tshwm sim txhua xyoo kub ntub chlorine, qhov kub ntawm 75 ~ 90 degree, yuav tsum tau ua los ntawm txias thiab ziab.

Hauv kev tsim khoom thiab sib dhos ntawm lub tuam txhab ionic membrane caustic soda, cov ntawv thov tseem ceeb ntawm titanium muaj xws li: anode kua tso tsheb hlau luam hauv lub tshuab anode; cov cua sov thiab cov twj tso kua mis concentrated brine hauv cov concentrated brine system; desalination twj, dechlorination yees, desalination dispensers, cov twj paj nruag thiab cov cua txias hauv desalination system; coolers, nqus yees thiab loosens rau sodium hypochlorite system; chlorine ntub dej txias rau cov tshuaj chlorine kho; kua theem ntsuas nyob rau hauv lub brine system; Thaum tshav kub kub exchangers thiab kiv cua nyob rau hauv lub de-etching system; lye ncig twj tso kua mis, lye coolers thiab piping rau saum toj no systems.

Thaum cov khoom siv titanium kis tau nrog hlau, nws txo nws txoj kev tiv thaiv corrosion, ua rau titanium ntau dua rau hydrogen absorption, thiab ua rau nkig hloov los ntawm cov txheej txheem ntawm hydrogenation leaching. Qhov hnyav dua cov hlau tsis huv, qhov hnyav dua qhov nqus dej ntawm titanium. Yog li ntawd, hauv kev ua, kev thauj mus los, kev teeb tsa, kev sib tsoo thiab kev saib xyuas cov khoom siv titanium, yuav tsum tsis txhob siv cov cuab yeej steel.

Cov khoom siv titanium thiab cov kav dej tau raug cuam tshuam rau qhov chaw luv luv thaum lub sijhawm ua haujlwm, tshwj xeeb tshaj yog cov chaw luv luv nrog qhov dav ntawm 0.5 hli. Kev yaig luv luv feem ntau tshwm sim nyob rau hauv lub tshav kub exchanger yeeb nkab thiab raj phaj nyob ib sab ntawm lub titanium thiab non-metallic gaskets nyob rau hauv qhuav, lwm yam ntawm kub siab tshaj 120 degree saturated brine kuj yog ib tug luv luv yaig.

Tiv thaiv kom tsis txhob muaj kev yaig luv luv uas siv tau yog: teeb tsa cov khoom siv thiab cov kav dej ntawm qhov txwv tsis pub luv luv thiab nyob ruaj khov; txais titanium-palladium alloy flange vuam nplhaib, feem ntau nrog titanium gaskets thiab titanium pob gaskets; Thaum tshav kub kub pauv nrog titanium raj thiab raj phaj ntawm qhov tau txais lub zog expansion thiab sealing weld; saturated brine kub tswj ntawm 70-85 degree .

Cov yam ntxwv ntawm ion membrane electrolysis alkali ntau lawm txheej txheem.

Ion membrane electrolysis alkali txheej txheem tsim, qhov zoo ntawm brine rau hauv lub tank yog siab heev, ntxiv rau kom ncav cuag ib qho concentration (305 ± 5g / L) thiab kub (77.5 ± 7.5 degree), cov ntsiab lus impurity ntawm brine rau hauv lub tank. kuj muaj cov kev cai nruj heev, yog li cov brine yuav tsum tau ua kom zoo thiab ua kom sov kom tau raws li qhov yuav tsum tau ua.
Txais ionic membrane electrolysis alkali txheej txheem, kev tsim khoom yuav tsum tshwm sim txhua xyoo high-temperature ntub chlorine, qhov kub ntawm 75 ~ 90 degree, yuav tsum tau ua los ntawm kev txias thiab ziab.

Ion membrane electrolysis alkali ntau lawm txheej txheem, vim yog vim li cas lawm, electrolysis ntawm brine tshiab yuav muaj NaOH, Na2C03, Ba2+, ClO-, C1O3- thiab lwm yam impurities; electrolysis ntawm tshiab brine kub ntawm 83-85 degree C; cathode tank ua rau caustic soda concentration ntawm 28% -32%, qhov kub yog 85 degree C..

NaCl nyob rau hauv brine thiab NaOH, Na2C03, ClO-, C1O3- thiab lwm yam impurities nyob rau hauv tshiab brine, raws li zoo raws li high-temperature wet chlorine, caustic soda, thiab lwm yam yog heev erosive, thiab zoo tib yam cov ntaub ntawv hlau tsis tuaj yeem tiv taus qhov no. kev yaig. Cov cim no txiav txim siab hauv ionic membrane electrolysis alkali cov txheej txheem tsim khoom, yuav tsum muaj kev xaiv ruaj khov ntawm nws cov khoom sib dhos thiab cov khoom siv hauv cov kav dej, txwv tsis pub cov khoom lag luam yuav khiav, muaj kev pheej hmoo, drips, to thiab lwm yam tshwm sim, cuam tshuam rau kev tsim khoom thiab cov khoom kom muaj nuj nqis. kev saib xyuas cov cuab yeej kho kom zoo nkauj thiab cov nqi tsim khoom.

Thib ob, ionic membrane caustic soda cov cuab yeej xaiv cov khoom siv titanium raws li.

Titanium nyob rau hauv lub teev ntawm tsawg dua los yog sib npaug rau 140 degree, nyob rau hauv ntau yam concentrations ntawm sodium chloride tov yog yuav luag tsis eroded, dua stainless hlau 316L thiab tooj liab-nickel alloy muaj ib tug ntau dua corrosion kuj; titanium muaj lub zog passivation, tuaj yeem kho qhov kev saib xyuas puas ntawm oxidized zaj duab xis; Cov cuab yeej ntawm ntshiab titanium tsis rhiab rau qhuav yaig, taw tes yaig, intergranular yaig, kev ntxhov siab yaig thiab lwm yam. Titanium muaj zog corrosion kuj nyob rau hauv kub ntub chlorine roj. Titanium nyob rau hauv chav tsev kub chlorine erosion tus nqi ntawm 0.00565mm/a; hauv 80 degree chlorine dej, qhov yaig ntawm 0.00431mm / a; hauv 95% ntawm cov roj chlorine ntub dej, titanium ntawm chav tsev kub yaig ntawm 0.0096mm / a.

Titanium yog superior rau lwm cov hlau vim qhov tsis zoo infiltration ntawm profile oxide zaj duab xis, qhov profile yog du thiab tsis-erosive, tsis yooj yim rau scale. Titanium lub thermal conductivity yog qis dua carbon steel thiab tooj liab, zoo ib yam li stainless hlau, tab sis titanium muaj corrosion kuj zoo heev. Yog li ntawd, cov phab ntsa tuab tuaj yeem ua thinned ib xyoos ib zaug, titanium profile thiab chav cua kub hloov mus rau drip condensation, tshem tawm cov thermal tsis kam, titanium profile tsis scale, yog li ntawd titanium lub tshav kub hloov mus ua haujlwm tau zoo, kev tsim kho ntawm erosive media heat transfer equipment.

Vim tias titanium muaj kev tiv thaiv zoo heev, ionic membrane caustic soda cov cuab yeej siv ntawm titanium khoom kho kom zoo nkauj muaj txiaj ntsig zoo dua: Ua ntej, txuas lub neej ua haujlwm ntawm cov khoom siv kho kom zoo nkauj, tshem tawm qhov zaus ntawm cov khoom kho kom zoo nkauj thiab cov kav dej tu, hauv paus daws teeb meem ntawm kev khiav, bubbling, dripping, leaking, thiab lwm yam., txuag lub zog thiab ua rau lub sijhawm tsim khoom muaj txiaj ntsig. Qhov thib ob, kev tswj cov khoom siv titanium thiab cov kav xa dej tuaj yeem tshem tawm cov nqi ntawm cov khoom siv thiab cov kav dej thiab txo cov nqi tsim khoom. Kev siv cov khoom siv titanium, tau kawg, kev nqis peev ib zaug yog hmo ntuj, tab sis los ntawm cov ntsiab lus dav dav, nyob rau lub sijhawm ntev yog kev lag luam. Kev nqis peev tiag tiag ntawm titanium tsuas yog ob zaug ntau dua li ntawm cov hlau tsis muaj steel vim tias lub neej ua haujlwm ntev ntawm cov khoom titanium, yog li tshem tawm cov nqi kho dua tshiab thiab nquag tu cov khoom siv thiab cov kav dej, uas ua tau txuag thiab txo cov nqi. Kev khiav hauj lwm 1t ntawm cov khoom siv titanium tuaj yeem tau txais txiaj ntsig kev lag luam ntawm 100, 000 RMB ib xyoos. Txij li thaum titanium coils tuaj yeem tswj qhov kev yaig ntawm cov cuab yeej teeb tsa thiab cov kav dej, kev yaig ntawm cov cuab yeej teeb tsa thiab cov kav dej yog txwv tsis pub muaj cov dej ntsev thiab dej qab ntsev.
