Kev lag luam hlau thiab hlau yog cov pob txha ntawm cov txheej txheem niaj hnub no, tab sis nws ntsib kev nyuaj siab los txo cov nqi ua haujlwm thiab kev cuam tshuam ib puag ncig. Ib qho txiaj ntsig tseem ceeb rau ob qho tib si yog kev cia siab rau cov txheej txheem pa oxygen, xws li cov nroj tsuag cryogenic lossis kua oxygen (LOX) xa khoom. Qhov no yog qhov twgVPSA (Nqus Siab Viav Adsorption) Oxygen Generatorstawm los ua ib qho kev hloov pauv thiab muaj txiaj ntsig zoo, ncaj qha tsom mus rau ib qho ntawm kev lag luam tus nqi sib txawv loj tshaj plaws: kev siv hluav taws xob.
Tus nqi siab ntawm Oxygen hauv Steelmaking
Oxygen yog ib qho tseem ceeb hauv cov txheej txheem steelmaking xws li Basic Oxygen Furnaces (BOF), hluav taws xob arc rauv, thiab ladle refining rau decarburization, combustion enhancement, thiab post-combustion. Kev lig kev cai, kev muab cov pa oxygen no yog lub zog - hnyav heev. Cryogenic cov nroj tsuag muaj cov nqi peev siab thiab lub zog tseem ceeb xav tau rau huab cua liquefaction, thaum yuav cov khoom siv ua kua oxygen sib txuas rau cov nqi lag luam tsis hloov pauv thiab kev thauj mus los. Rau ib qho nruab nrab - loj steel cog, cov pa oxygen tuaj yeem suav rau feem ntau ntawm nws daim nqi hluav taws xob tag nrho.
Yuav ua li cas VPSA Technology txiav kev siv hluav taws xob los ntawm kev tsim
Lub tshuab hluav taws xob VPSA ua haujlwm ntawm qhov yooj yim dua, lub zog ntau dua -txoj cai zoo piv rau cryogenic distillation. Nov yog qhov nws ua haujlwm kom txuag tau lub zog:
Ambient Air Intake & Pretreatment:Lub kaw lus rub tawm hauv huab cua ambient, uas yog lim kom tshem tawm cov khoom.
Tsawg-Pressure Adsorption:Cov huab cua yog dhau los ntawm ib lub nkoj uas muaj atshwj xeeb Zeolite molecular sieveuas xaiv adsorbs nitrogen, dej vapor, thiab lwm yam gases nyob rau hauv ib tug me ntsis lub nqus tsev vacuum los yog tsis tshua muaj siab, cia oxygen (90-95% purity) dhau mus. Cov txheej txheem siab - qis qis no yog qhov muaj zog tsawg dua- hnyav dua li qhov siab-compression thiab txias txias uas yuav tsum tau muaj hauv cov tshuab cryogenic.
Regeneration Cycle:Ib lub nkoj thib ob rov tsim dua lub sieve los ntawm kev tso cov pa adsorbed rau hauv cov huab cua hauv lub tshuab nqus tsev, tsim kom muaj lub voj voog txuas ntxiv. Niaj hnub nimno VPSA systems sivLub tshuab nqus tsev twj tso kua mis thiab optimized lub sij hawm voj voogkom txo tau lub zog yuav tsum tau rau lub sij hawm regeneration no.
Qhov kev ua tau zoo ntawm qhov tseem ceeb yog nyob rau hauv kev ua haujlwm nyob ze - qhov kub thiab txias thiab zam lub zog loj ntawm cov huab cua liquefying.Niaj hnub VPSA cov nroj tsuag tuaj yeem ua tiav kev txuag hluav taws xob ntawm 30-50% piv rau cov nroj tsuag cryogenicrau tib lub ntim ntawm oxygen tsim.
Direct Nqi Txuag & Cov txiaj ntsig ua haujlwm rau Steel Mills
Kev ua raws li ntawm -site VPSA oxygen generator txhais ua kev ntsuas nyiaj txiag thiab kev ua haujlwm zoo:
- Tus nqi ua haujlwm qis dua:Thawj qhov kev txuag yog nyob rau hauvtxo kev siv hluav taws xob, uas ncaj qha txo tus nqi rau ib chav tsev ntawm cov pa oxygen tsim. Qhov no decouples koj cov nqi oxygen los ntawm tus nqi muag khoom sab nraud.
- Kev tshem tawm cov nqi logistics thiab pheej hmoo:Tsis muaj nuj nqis ntxiv rau LOX tanker xa khoom, chaw cia tank, lossis evaporation poob. Qhov no ua kom muaj kev ruaj ntseg,tsis cuam tshuam ntawm - qhov chaw muab khoomkev tiv thaiv kab mob rau cov khoom lag luam cuam tshuam.
- Scalability thiab Flexibility:VPSA units yog modular. Koj tuaj yeem txhim kho lub peev xwm ua tau raws li koj qhov kev xav tau tiag tiag thiab nce qib raws li kev tsim khoom loj hlob, zam dhau - nqis peev. Lawv tuaj yeem ua haujlwm tau zoo ntawm cov khoom sib txawv (xws li, 50-100% muaj peev xwm) kom phim cov sijhawm tsim khoom.
- Txo Cov Nyiaj Siv Tau Ua Haujlwm:Nrog tsawg dua qhov txav mus los thiab tsis muaj cov khoom siv cryogenic nyuaj, VPSA systems feem ntau xav tau kev saib xyuas tsawg dua li cov nroj tsuag cryogenic, ua rau txo qis dua - cov nqi kev pabcuam sijhawm.
Qhov tiag -Kev cuam tshuam hauv ntiaj teb: GNEE Case Study
Ib lub tuam txhab hlau ua lag luam nyob rau sab hnub tuaj Asia tau koom tes nrog GNEE los daws nws cov nqi hluav taws xob nce siab. Los ntawm kev hloov nws cov aging cryogenic system nrog akev cai -engineered GNEE VPSA Oxygen Plant(muaj peev xwm: 2,500 Nm³ / hr, purity: 93%), lub zeb ua tiav cov txiaj ntsig zoo tshaj plaws hauv thawj xyoo:
Kev siv zog rau kev tsim cov pa oxygen poob los ntawm 38%.
Tag nrho cov nqi ua haujlwm txhua xyoo rau cov khoom siv oxygen tau txo qis dua$450,000.
Qhov project tiav arov qab los ntawm kev nqis peev (ROI) tsawg dua 2.5 xyoo.
Kev ntseeg siab ntawm - qhov chaw muab khoom kuj tau txhim kho cov txheej txheem sib xws hauv lawv txoj haujlwm BOF.
VPSA vs. Cov Txheej Txheem Txheej Txheem: Kev Xaiv Kom Zoo
