Hauv kev tsim cov hlau thiab tshuaj lom neeg, cov khoom siv hluav taws xob tsis tu ncua thiab ruaj khov cuam tshuam ncaj qha rau cov zis, kev siv hluav taws xob, thiab kev nyab xeeb ntawm kev ua haujlwm. Piv nrog rau kev yuav cov pa oxygen ib txwm muaj, ntawm -qhov chaw muaj cov pa oxygen generators tau dhau los ua qhov kev xaiv zoo rau ntau lub tuam txhab. Shenger Gas, raws li ib tug neeg ua si nyob rau hauv qhov chaw sib cais roj, tsom mus rau yuav ua li cas oxygen tsim technologies haum txawv tiag tiag - ntiaj teb no tej yam kev mob. Kab lus no saib seb cov tshuab hluav taws xob muaj pa oxygen coj tus nqi rau cov hlau thiab tshuaj lom neeg li cas, thiab yuav tsum xav txog dab tsi thaum xaiv lub kaw lus.
Kev Lag Luam Hlau: Los ntawm Oxygen Enrichment rau Blast Furnace Support
Kev tsim cov hlau siv ntau cov pa oxygen. Qhov nruab nrab, kev tsim ib tuj ntawm cov hlau tsis huv yuav tsum muaj li 100 txog 150 cubic meters ntawm cov pa ntshiab. Cov ntawv thov tseem ceeb suav nrog:
1. Oxygen-enriched blast furnace txhaj
Ntxiv cov pa ntshiab huv rau lub tshuab cua kub cua ua kom kub hnyiab ntawm lub tuyere, tso cai rau ntau dua pulverized thee txhaj, thiab txo cov kev siv coke. Nyob rau hauv kev xyaum, txhua 1% nce nyob rau hauv oxygen enrichment nce thee txhaj tshuaj los ntawm 15-20 kg ib ton ntawm hlau, thiab txo coke noj li ntawm 5-8 kg ib ton ntawm hlau. Cov tshuab hluav taws xob muaj oxygen muab 90% rau 99.6% oxygen concentration. Ob leeg VPSA (lub tshuab nqus tsev siab viav vias adsorption) thiab cryogenic cua sib cais chav nyob tuaj yeem ua tau raws li qhov xav tau ntawm cov pa hluav taws xob txuas ntxiv ntawm qhov cub tawg.
2. Basic oxygen rauv (BOF) steelmaking
BOF cov txheej txheem yuav tsum muaj siab -purity oxygen (Ntau dua lossis sib npaug li 99.5%) rau decarburization thiab tswj kub. Cov pa oxygen xav tau hloov pauv sai, nrog qhov siab kawg ntws mus txog 20,000 txog 80,000 Nm³ / h. Cryogenic huab cua sib cais chav tswj cov nqi ntws siab thiab siab purity, thaum cov kua oxygen backup ua kom ruaj khov. Byproduct nitrogen thiab argon kuj txhim kho kev lag luam tag nrho.
3. Hluav taws xob arc rauv (EAF) thiab ladle refining
EAF melting txiaj ntsig los ntawm cov pa oxygen-pab combustion, shortening melting cycles. Hauv ladle refining furnaces (LF), oxygen txhawb desulfurization thiab dephosphorization tshwm sim. Cov ntawv thov no xav tau cov pa oxygen sib nrug ntawm 0.8-1.2 MPa. VPSA oxygen generators, nrog rau lawv pib hloov tau yooj yim - nres muaj peev xwm thiab kev kho yooj yim dua, tau txais los ntawm ntau qhov nruab nrab- cov nroj tsuag steel loj.
Xaiv cov lus qhia
Rau cov loj sib xyaw steel mills uas ua tau ntau tshaj 3 lab tons hauv ib xyoos, cryogenic cua sib cais nrog kua thaub qab yog tus qauv xaiv. Rau cov mills me me nyob rau hauv 1 lab tons, los yog rau cov cua sov ua kom muaj zog, VPSA units muab 30-40% qis dua kev nqis peev thiab 15-25% qis dua tag nrho cov nqi khiav lag luam.
Kev lag luam tshuaj: Rigid Demand rau Oxidation thiab Gasification
Cov nroj tsuag tshuaj xav tau ntau dua thaum nws los txog rau oxygen purity, siab, thiab kev ntseeg tau, vim tias cov nqi oxygen ncaj qha cuam tshuam rau cov khoom lag luam kawg.
1. Ammonia thiab methanol ntau lawm
Hauv cov pa roj carbon monoxide lossis thee-raws li kev tsim cov ammonia, cov pa ntshiab yog xav tau rau ib nrab oxidation gasification los tsim syngas (CO + H₂). Oxygen purity yuav tsum yog tsawg kawg yog 99.5%, nrog nruj txwv ntawm impurities xws li argon. Ua ib tuj ntawm ammonia siv li ntawm 700-850 Nm³ ntawm oxygen. Cov dej num loj loj feem ntau yog nruab nrog cov cua txias cua sib cais, uas tseem muab cov nitrogen rau purging thiab sealing.
2. Ethylene oxide / ethylene glycol (EO / EG)
Cov catalyst siv los oxidize ethylene rau hauv ethylene oxide yog rhiab heev rau oxygen purity. Methane cov ntsiab lus hauv oxygen yuav tsum nyob qis dua 0.1%, thiab tag nrho cov sulfur qis dua 0.1 ppm. Daim ntawv thov no yuav tsum tau ua kom muaj cov pa oxygen cryogenic, ua raws li kev ntxiv desulfurization thiab ziab cov kauj ruam.
3. Coal gasification thiab IGCC
Entrained -flow gasification technologies (xws li Plhaub, GSP, los yog tawm tsam multi-burner designs) xav tau cov pa oxygen ntawm 4.0-8.5 MPa nrog kev ruaj khov. Cov txheej txheem kev lag luam yog cryogenic oxygen ntau lawm ua ke nrog siab - siab ua kua oxygen twj thiab vaporization. Rau qis dua -siab ruaj- txaj gasifiers, 90–93% oxygen-enriched cua tuaj yeem txhim kho gasification siv. Nyob rau hauv cov ntaub ntawv no, VPSA units muab tus nqi qis dua - lwm tus nqi.
4. Kev kho dej khib nyiab thiab ozone oxidation
Chemical industrial parks nquag siv ozone oxidation los rhuav tshem cov organic tebchaw hauv cov dej khib nyiab. Ozone tsim yuav tsum tau noj cov pa oxygen. Cov dej me me (tsawg dua lossis sib npaug li 500 Nm³ / h) ntawm 90-95% purity txaus. Compact PSA oxygen generators yog qhov haum zoo ntawm no - lawv khiav tau, xav tau qhov chaw me me, thiab tuaj yeem ntsia sab nraum zoov.
Qhov taw qhia tus nqi tseem ceeb
Hauv cov phiaj xwm tshuaj, suav cov nqi oxygen rau ib chav tsev ntawm cov khoom yog qhov tseem ceeb. Yog tias cov nqi hluav taws xob ntau tshaj 0.6 yuan / kWh thiab cov pa oxygen xav tau ruaj khov, cov chav ua haujlwm cryogenic qhia tau zoo dua. Yog tias hluav taws xob pheej yig dua thiab tsis muaj qhov xav tau los ntawm cov khoom lag luam (argon, helium), VPSA oxygen generators siv tsuas yog 0.35–0.45 kWh ib Nm³ (ntawm 90% purity) - tus nqi- kev xaiv zoo rau cov tshuaj zoo los yog thaum ntxov -theem thee chemical peev.

Hauv qee qhov haujlwm tiag tiag, cov nroj tsuag siv kev sib xyaw ua ke: cryogenic units rau kev tsim khoom loj (siab purity) thiab VPSA rau qis dua - qib oxygen thov (xws li, kev kho ib puag ncig). Qhov no sib npaug cov peev thiab cov nqi hluav taws xob.
Peb qhov tiag -Lub Ntiaj Teb Yam Tseem Ceeb Uas Muaj Feem Cuam Tshuam Oxygen Generator Performance
Raws li kev tawm tswv yim los ntawm ntau qhov chaw ua haujlwm, cov yam ntxwv no tsim nyog saib ua ntej xaiv:
1. Inlet cua zoo
Cov nroj tsuag hlau thiab tshuaj lom neeg feem ntau tso tawm SO₂, NOx, plua plav, thiab hydrocarbons rau saum huab cua. Rau cov chav nyob cryogenic, qhov no txhais tau tias ntxiv molecular sieve adsorbers thiab teem caij tu ncua sij hawm. Rau VPSA systems, zeolite molecular sieve tau txwv kev zam rau acidic gases. Inlet cua yuav tsum dhau los ntawm desulfurization yees thiab siab - lim dej; txwv tsis pub, molecular sieve lub neej yuav poob los ntawm 5-8 xyoo mus rau 2-3 xyoos.
2. Qhov cua nkag thiab thauj khoom yooj
Hlau cog cov pa oxygen xav tau tuaj yeem ua viav vias los ntawm 30-40% nruab nrab ntawm qhov siab tshaj thiab tawm - teev. Cryogenic units xav tau cov kua oxygen cia tso tsheb hlau luam rau lub ncov shaving, los yog kev koom ua ke nrog argon system. VPSA units kho load nruab nrab ntawm 50% thiab 100% los ntawm kev hloov blower ceev thiab adsorption lub sij hawm, tab sis cov lus teb yuav siv sij hawm txog 30 vib nas this - ceev txaus rau feem ntau mills.
3. Kev tu cov neeg ua haujlwm muaj peev xwm
Cryogenic huab cua sib cais yuav tsum muaj cov neeg ua haujlwm txawj uas nkag siab txog turbomachinery, kev tswj kab ke distillation, thiab cov txheej txheem kev nyab xeeb. Kev cob qhia siv sijhawm 6-12 lub hlis. PSA thiab VPSA units khiav ntawm PLC-raws li automation. Kev saib xyuas txhua hnub feem ntau suav nrog kev hloov cov lim dej thiab topping li molecular sieve, ua rau lawv haum rau cov pab pawg me.
Hauv ob xyoos dhau los, tus nqi hluav taws xob hloov pauv thiab lub zog los txiav cov pa roj carbon ntau tau thawb ntau cov hlau thiab tshuaj nroj tsuag kom rov- ntsuas ntawm - qhov chaw tsim cov pa oxygen. Ob txoj hauv kev tau txais traction. Ib qho yog siv cov khib nyiab pov tseg los ntawm qhov cub tawg slag flushing dej rau preheat molecular sieve regeneration gas, txiav chav siv. Lwm qhov yog kev loj hlob ntawm kev siv qis -purity oxygen enrichment (25%-35%) hauv reheating furnaces thiab rotary kilns, uas tau tsav kev thov rau ntau lub me me VPSA oxygen generators.
Xaiv lub tshuab hluav taws xob oxygen tsis yog hais txog kev sib piv cov nqi khoom siv xwb. Koj yuav tsum tau ua kom muaj pa purity, siab, ntws variation, hluav taws xob nqi, dab tsi koj yuav muag byproducts rau, thiab txij nkawm ncua sij hawm - tag nrho rau hauv tus nqi kawg rau ib tuj ntawm oxygen. Shenger Gas muab cov lus qhia ncaj nraim zoo nkauj rau cov neeg siv khoom: ua ntej, ncaj ncees taug qab koj cov ntaub ntawv siv oxygen rau rau lub hlis, tom qab ntawd txiav txim siab txog txoj hauv kev. Txwv tsis pub, koj them nyiaj ntau dua rau cov yam ntxwv uas koj yuav tsis siv, lossis koj tau daig nrog lub raj mis uas koj tsis tuaj yeem tawg.
