1. Pib
Cov roj tsis tshua muaj pa nrog cov roj nrog cov ntsiab lus tsawg hauv cov huab cua, suav nrog kev ntseeg, Krypton, thiab lwm yam. Argon yog qhov tsis tshua muaj pa hluav taws xob hauv kev lag luam. Nws yog qhov tsis muaj zog heev thiab tsis hlawv lossis txhawb kev txhawb nqa. Argon yog tsuas yog siv rau kev tsim khoom, electronics, hlau smelting thiab lwm yam lag luam. Piv txwv li, thaum pom txhuas, magnesium, tooj liab thiab cov hlau uas tsis siv hluav taws xob los tiv thaiv cov roj welded los ntawm kev ua pa lossis nitrided los ntawm huab cua. Hauv kev tsim khoom lag luam ntawm cov qauv argon muaj feem cuam tshuam nrog cov qauv khoom lag luam, kev nqis peev thiab siv hluav taws xob ntawm cov cuab yeej.
2. Taw qhia rau cov pa loj
Chav ntsuas hluav taws xob loj hauv ib qho cheeb tsam npaj ua kom muaj cov pa sib cais ua pa nrog cov pa oxygen ntau lawm ntawm 50, {1}} nm3 / h. Chav tsev npaj yuav siv cov kub siab tshaj tawm kev ua kom huv, cov khoom siv pa roj av thiab cov pa hluav taws xob sib txawv thiab tag nrho huab cua compressor tsev tsav.
3. Txheej Txheem Flow thiab Cov yam ntxwv ntawm Argon Ntau Lawm
Cov txheej txheem feem ntau siv rau kev tsim ntawm cov Argon yog tag nrho cov txheej txheem yooj yim, kev ua haujlwm yooj yim, kev nyab xeeb thiab siab sib cav sib luag. Tag nrho distillation kev tsim tawm argon yog coj cov txheej txheem sib cav los ntawm cov pej xeem sab saud, thiab tau txais cov ntsiab lus argon nrog cov ntsiab lus oxygen ntawm<1.5 × 10-6. Then, separate argon and nitrogen in the refined argon tower to obtain a high-purity argon product with a purity of 99.999% (argon content).
4. Kev Tshawb Fawb thiab Kev Ntsuam Xyuas ntawm Argon kev ua lag luam hauv qee thaj av
Raws li daim ntawv tshuaj ntsuam no, muaj 9 txoj kev sib cais nrog ntau qhov chaw ua haujlwm ntawm 5860 nm3 / h (raws li cov khoom tsim muaj), uas yog, 84, {t / a. Ib qho ntxiv, vim qhov tseeb tias cov txheej txheem sib cav ntawm qee cov haujlwm tsis tau muab tso rau hauv kev siv lossis cov zis yog tsawg, cov zis tiag tiag yog li 63,000 t / a. Feem ntau, cov argon ntau lawm muaj peev xwm nyob rau hauv thaj av no yog me me.
Nws tau to taub tias cov nqi tsheb thauj mus los ntawm cov kua argon yog {0}}. 8 txog 1.0 xyoos. Tus nqi sib txawv ntawm cov kev lag luam tsis pub dhau 200 km yog theoretically li 160 yuan / t; Ib yam li ntawd, tus nqi sib txawv ntawm ob lub khw 500 km sib cais ntau dua 400 yuan / t, thiab cov lag luam txuas nrog. Nws tau to taub tias tus lag luam nqe ntawm argon nyob rau hauv thaj av no yog 800 txog 1900 yuan / t (suav raws li tus nqi nruab nrab txhua xyoo ntawm 1000 leej niam).
Rau 5 {0, 000-}}}} yog cov khoom lag luam. Kev siv hluav taws xob, kev siv zog siv tau ntawm kev sib cais ua haujlwm thiab liquefaction ua haujlwm (kev ua haujlwm compression yog tag nrho cov oxygen thiab nitrogen). Nws tau paub tias theoretical li cas liquefaction ua haujlwm ntawm argon yog {}}}} € 0. {{{{Mw · h / t. Kev sib cais ua haujlwm tau muab xam raws li cov qauv: w {} rt (NO2LN + NN2LN + NN2LN + NN2LN + NN2LN + NN2LN + NNTIVE, R yog Universal Pauv tas li; T yog lub ambient kub; No2, NN2, NAR yog tus nqi ntawm cov pa, nitrogen, thiab kev sib cav feem ntau; PO2, PN2, par yog ib feem ntawm cov pa oxygen, nitrogen, thiab argon fab sib xws; p yog tag nrho cov siab.
Los ntawm kev muab xam, nws tuaj yeem tau txais uas theoretical tsawg kawg nkaus kev sib cais ua haujlwm ntawm 1 nawj3 (suav}. {}}.} K} {}. {}} Kuv yog tus. {{9 {9}}}, 000 × × 0.02 × 8%)=148 kw · h / T. Hauv cov ntsiab lus, tus nqi ntau lawm ntawm tus nqi ntawm Argon yog suav txog 316 KWAH H / T, lossis 139 yuan / t.
Cov ntaub ntawv npog cov neeg siv khoom hauv 200 thiab 500 km, ntxiv rau tus nqi thauj mus los, tag nrho cov nqi yuav yog hais txog 299 thiab 539 yuan, uas tseem muaj qee qhov txiaj ntsig.
Lub tsheb thauj mus los dav dav ntawm thaj chaw no los ntawm thaj chaw lag luam ntawm lub peev xwm ntawm xeev tsuas yog 100 km. Nyob rau yav tom ntej, nrog lub xeev "lub peev txheej muaj zog" kev lag luam tsim kho, yuav siv cov khoom lag luam ntawm kev tsim kho, thiab kev lag luam xav tau rau Argon yuav nce raws li.
5. Kev pheej hmoo thiab lub zog kev txheeb xyuas ntawm Argon Ntau Lawm
Rau zus ntawm argon, cov txheej txheem distilling cov txheej txheem ntau lawm yog technically, thiab yuav tsis nce kev nyab xeeb ntawm lub cuab yeej. Qhov kev teeb tsa ntawm lub kaw lus argon tseem yuav ua rau cov pa oxygen thiab muaj lub zog txuag hluav taws xob tseem ceeb. Rau 50, 000- qib cua sib cais, lub cav sib cais yog li 1500 nm3 / h (Argon extraction tus nqi yog 70%). Kev sib piv yog ua rau hauv kev siv hluav taws xob, kev nqis peev, thiab cov nyiaj tau los, raws li qhia hauv Table 2.

Rooj 2 Kev sib piv ntawm Schemes rau kev teeb tsa Argon System
Txij li ntau dua 90% ntawm lub zog siv ntawm cov pa sib cais yog tsim los ntawm huab cua compressor thiab lub koob tshuaj tiv thaiv, peb suav cov hluav taws xob txo los ntawm kev teeb tsa lub teeb meem ntawm kev sib cav sib ceg. Qhov nrawm dua tus nqi ua, nrawm dua rau hauv qab ntawm cov dej khov kho, thiab cov phab ntsa sab hauv ntawm lub tank kom muaj kev ntxhov siab ntau dua. Nyob rau hauv lub superposition ntawm ob peb qhov kev nyuaj siab, kev ntxhov siab hauv zos yog aggravated. Lub zos kev ntxhov siab hauv cheeb tsam muaj cov kev coj ua haum rau kev tsim thiab nthuav dav ntawm cov kab nrib pleb. Nyob rau hauv lub ncaj ntug ntawm lub taub hau qhov twg qis-kub nruj yog qhov tsis muaj zog, cov npoo nplej ze rau ntawm lub tshuab hluav taws xob sib tsoo. Raws li kev txiav txim ntawm kev ntxhov siab hauv zos, cov kab nrib pleb txuas ntxiv nthuav dav raws cov nplej los yog hloov chaw thiab thaum kawg nkag mus thiab ua rau lub tank poob.
6. Cov lus qhia
1. Qhov tsis ua tiav kev tawg ntawm lub taub hau cryogenic tank lub taub hau yog qhov qis-kub brittle tawg los ntawm kev ntxhov siab hauv lub tank. Qhov tawg keeb kwm los ntawm sab hauv ntawm sab ncaj tog ntug ntawm lub taub hau sab nraum qhov kub-cuam tshuam weld. Cov kab nrib pleb hauv thaj chaw tawg thiab sab hauv yog tsuas yog intergranular cracks, thiab cov chaw txuas ntxiv yog intergranular thiab transgranular cleavage brittle cracking.
2. Thaum lub sijhawm tsim qauv ntawm ntu ncaj ntawm lub taub hau, ua rau muaj kev ntxhov siab theem yog lub ntsiab tseem ceeb ntawm cov khoom muaj zog qis hauv lub taub hau me me.
3. Qhov kev tawm tsam ntau dhau ntawm Cryfate ntxiv dag zog rau cov khoom tawgyogenic nce cov khoom tawg, thaum ua rau muaj kev ntxhov siab ntau dua, uas ua kom nrawm dua rau cov khoom tawg.
4. Qhov kub sib txawv kev ntxhov siab tsim los ntawm cov sib quas ntus txhaws ntawm cov kua nitrogen thaum siv lub tank kuj tseem nrawm nrawm thiab tawg txuas ntxiv.

1. Lub hom phiaj ua rau martensite theem kev hloov pauv los ntawm kev tiv thaiv txias ntawm cov hlau tsis xeb yog qhov kub thiab txias, tus nqi deformation thiab deformation npaum li cas thiab deformation tus nqi. Nws raug nquahu tias kev sib sau sov no tau siv rau lub taub hau kev ua kom txo cov khoom siv ntawm deformation martensite thiab cov khoom siv deformation ua kom tawv nqaij tawv. Tom qab lub taub hau yog tsim, cov ntsiab lus ferrite ferrite tuaj yeem kuaj pom los ntawm cov qauv sib nqus. Cov ntsiab lus ferrite ferrite feem ntau yuav tsum tau tswj hwm qis dua 15%. Rau lub taub hau uas nws sib npaug ntawm cov ntu ncaj tshaj qhov yuav tsum tau siv, yog li cov plastonity thiab tawv ntawm cov khoom tuaj yeem rov qab los yog txhim kho;
2. Thaum twg muaj ntxiv dag zog rau lub tank cia, tus nqi deformation yuav tsum tau tswj kom nruj ua kom muaj kev ntxhov siab, thiab txo qis kev ntxhov siab.
