Hauv cov haujlwm loj -scale kev lag luam, kev ruaj ntseg ntawm cov pa oxygen ncaj qha cuam tshuam rau kev tsim khoom txuas ntxiv thiab cov nqi khiav lag luam. Rau cov ntawv thov uas xav tau cov pa oxygen loj thiab nruab nrab purity (feem ntau yog 90%-95%), cov pa oxygen ib txwm siv lossis PSA systems txhua tus muaj kev txwv. VPSA oxygen generators-Lub tshuab nqus tsev siab viav vias Adsorption tshuab-tau nce ntxiv los ntawm cov tuam txhab engineering thiab cov cuab yeej sib koom ua ke raws li txoj hauv kev tseem ceeb.
Shenger Gas tau ntev tau koom nrog hauv kev lag luam roj sib cais, nrog cov kev txawj ntse hauv kev tsim kho kom haum ntawm cov thev naus laus zis no. Kab lus no tham txog tus nqi, kev sib xyaw ua ke, thiab kev xaiv tseem ceeb ntawm VPSA oxygen generators hauv cov haujlwm loj.
Vim li cas Kev Lag Luam Loj Loj Txaus Siab rau VPSA
Kev siv cov pa oxygen loj hauv kev lag luam- xws li tsis yog- ferrous hlau smelting, ozone oxidation, iav furnace enrichment, thiab pulp bleaching- qhia cov yam ntxwv:
- Kev xav tau oxygen tsis tu ncua nrog cov nqi qis qis
- Cov pa oxygen loj, xws li ntau pua mus rau txhiab Nm³ / h
- Purity yuav tsum feem ntau ntawm 90%-95%, tsis yog ultra-siab purity siab tshaj 99.5%
Qhov sib txawv tseem ceeb ntawm VPSA thiab PSA ib txwm muaj nyob rau hauv lub tshuab nqus tsev desorption kauj ruam, uas ua rau kom muaj kev sib xyaw ua kom zoo dua qub thiab txo qis zog siv rau ib chav tsev ntawm oxygen. Hauv cov haujlwm loj, qhov sib txawv ntawm qhov kev ua tau zoo no txhais ncaj qha mus rau qhov sib txawv ntawm cov nqi khiav haujlwm txhua xyoo.
Piv nrog rau cov kua oxygen tank cov khoom, VPSA zam tsis dhau tus nqi volatility, xa cov sij hawm txaus ntshai, thiab kev saib xyuas lub nra ntawm cryogenic cia tso tsheb hlau luam. Thaum ua haujlwm, cov pa oxygen yog tsim tawm ntawm - qhov chaw thiab ntawm - kev thov, muab cov neeg siv kev tswj hwm tag nrho.
Txheej Txheem Txheej Txheem ntawm VPSA System
VPSA oxygen system rau cov haujlwm loj hauv kev lag luam feem ntau suav nrog cov chav tseem ceeb hauv qab no:
1. Lub tshuab nqus tsev thiab lub tshuab nqus tsev twj tso kua mis
Qhov no yog lub zog tseem ceeb ntawm lub system. Lub tshuab nqus tsev muab siab adsorption, thaum lub tshuab nqus tsev twj tso kua mis ua kom qis -siab desorption. Qhov kev ua tau zoo ntawm ob qho no ncaj qha txiav txim siab qhov tshwj xeeb siv hluav taws xob ib tuj ntawm oxygen.
2. Adsorption nkoj thiab tshwj xeeb Molecular Sieve
Ob lossis peb lub yees yog feem ntau siv nyob rau hauv alternating cycles. Cov molecular sieve nyob rau hauv VPSA muaj ntau dua - zaus siab thiab lub tshuab nqus tsev vacuum, xav tau ntau dua mechanical zog, nitrogen-oxygen cais kev ua tau zoo, thiab kev pab lub neej.
3. Tsis Siv Neeg thiab Kev Tswj Xyuas Siab
Lub qhov hluav taws xob oxygen los ntawm VPSA system muaj qhov hloov pauv me me. Lub tank loj txaus oxygen buffer, ua ke nrog lub siab tswj li qub, yog tsim nyog los xyuas kom meej cov khoom ruaj khov rau cov txheej txheem pipeline.
4. Kev ntsuas thiab tsis siv neeg tswj qhov system
Tej yaam num loj feem ntau yuav tsum tau saib xyuas tej thaj chaw deb, thauj khoom -ua raws, thiab kev ua txhaum tus kheej- kuaj mob. PLC logic yuav tsum tau ua kom zoo rau cov yam ntxwv ntawm kev qaug zog ntawm cov molecular sieve, tsis tsuas yog theej los ntawm PSA logic.
Plaub qhov kev txiav txim siab tseem ceeb hauv Kev Xaiv Engineering
Thaum lub sij hawm kev ntsuam xyuas thiab kev tsim qhov project thaum ntxov, plaub yam nram qab no tsim nyog saib xyuas:
1. Cov pa oxygen xav tau tiag tiag profile
VPSA yog qhov zoo dua rau kev thauj khoom ruaj khov. Yog tias qhov xav tau oxygen hloov pauv sai heev nyob rau lub sijhawm luv luv, ntxiv cov pa oxygen ntxiv lossis cov phiaj xwm khoom siv sib xyaw yuav tsum xav txog.
2. Qhov chaw thiab huab cua puag ncig
Cov hneev taw ntawm VPSA cov cuab yeej yog me me, tab sis cov cua nkag thiab tso tawm ntawm lub tshuab nqus tsev thiab lub tshuab nqus tsev yog qhov nkag siab rau plua plav, av noo, thiab qhov siab. Kev kho muaj peev xwm yuav tsum tau ua rau siab - qhov chaw siab.
3. Kev sib piv ntawm kev siv hluav taws xob zoo
Cov nqi siv hluav taws xob tshwj xeeb los ntawm cov chaw muag khoom sib txawv feem ntau yog nyob ntawm thaj tsam sib txawv (inlet kub, tawm siab, purity hauv paus). Nws raug nquahu kom thov cov ntaub ntawv sib piv nyob rau hauv cov xwm txheej tsis sib xws.
4. Kev saib xyuas yooj yim
Hauv cov haujlwm loj, cov khoom siv yuav khoom feem ntau tsis yog tus neeg teb xov tooj kawg. Xaiv qhov kev teeb tsa nrog cov qauv meej thiab cov khoom seem yog qhov tseem ceeb rau kev ua haujlwm ntev -.
Qhia meej txog cov kev xav tsis zoo
- Tswvyim 1: VPSA purity tsis tshua muaj kev ntseeg siab tshaj li cov txheej txheem cryogenic
Qhov tseeb: Hauv 90% -95% purity ntau, VPSA muab kev tswj xyuas ruaj khov thiab ua tau raws li cov txheej txheem kev lag luam feem ntau.
- Tswvyim 2: VPSA tsuas yog haum rau cov nqi me me mus rau nruab nrab
Qhov tseeb: Ib leeg VPSA units ntawm ntau txhiab Nm³ / h yog cov paub tab, thiab muaj peev xwm loj tuaj yeem ua tiav nrog ntau qhov sib npaug.
- Tswvyim 3: Molecular sieve lifespan yog unpredictable
Qhov tseeb: Nrog rau kev kho kom zoo thiab ua haujlwm kom raug, kev pabcuam lub neej ntawm siab -zoo molecular sieves tuaj yeem tswj hwm kev ntseeg siab hauv engineering xav tau.
VPSA oxygen generators tau dhau los ua tus paub tab, kev lag luam, thiab nws tus kheej tswj tau kev daws teeb meem rau kev lag luam loj. Lawv tsis yog ib qho -loj- haum-txhua yam thev naus laus zis tab sis ua kom pom tseeb qhov zoo hauv qhov txuas ntxiv, nruab nrab -purity, nruab nrab- mus rau -loj ntws oxygen thov ntu.
Rau cov pab pawg ua haujlwm ntsuas ntawm - qhov chaw tsim cov pa oxygen, qhov tseem ceeb nyob hauv kev sib piv VPSA system configuration rau lawv qhov tshwj xeeb load profile, site tej yam kev mob, thiab tu muaj peev xwm. Shenger Gas ib txwm ua los ntawm cov kev xav tau tiag tiag ntawm engineering, muab cov ntsiab lus tseeb, txheeb xyuas qhov tseeb thiab cov kev daws teeb meem tsim nyog- ntau dua li cov ntsiab lus.
