I. Qhov Sib txawv ntawm Cov Ntsiab Lus Tseem Ceeb (Lub hauv paus ntawm Qhov Zoo)
Tsoos PSA Oxygen Generation Technology: Txais siv lub siab viav vias adsorption (PSA) hom nrog lub siab adsorption thiab atmospheric desorption. Lub siab adsorption feem ntau yog 0.6-1.0MPa, tso siab rau qhov siab - ib puag ncig kom ua tiav cov kev xaiv adsorption ntawm nitrogen los ntawm molecular sieves. Desorption yuav tsum tau depressurization rau atmospheric siab, ua kom tiav "pressurization-adsorption-depressurization-desorption" voj voog (lub sij hawm voj voog: kwv yees li 60-90 vib nas this).
VSA Oxygen Generation Technology (ib qho kev hloov pauv ntawm lub siab viav vias adsorption): Siv lub tshuab nqus tsev vacuum swing adsorption (VSA) hom nrog ze - atmospheric adsorption thiab nqus desorption. Lub adsorption siab yog ze rau atmospheric siab (0.1-0.2MPa), thiab thaum lub sij hawm desorption, lub siab nyob rau hauv lub adsorption ntauwd yog txo mus rau -0.06 ~ -0.08MPa ntawm lub tshuab nqus tsev twj, nrog lub sij hawm voj voog tsuas yog 20-40 vib nas this. Qhov kev sib txawv ntawm lub voj voog qis qis no yog lub hauv paus ua rau nws cov yam ntxwv ua haujlwm tseem ceeb.
II. Kev sib piv ntawm Tsib Core Performance Characteristics
1. Kev siv hluav taws xob: Cov nqi ua haujlwm tau zoo
PSA Technology: High-siab adsorption yuav tsum muaj siab- lub zog cua compressor los muab lub zog, ua rau lub zog siv ceev ntawm kwv yees li 0.45-0.6kWh/Nm³ O₂ (hauv qab 93% oxygen purity tej yam kev mob). Lub zog poob tseem ceeb tshwm sim thaum lub zog siab compression.
VSA Technology: Ze ntawm - atmospheric adsorption txo cov load ntawm lub tshuab cua compressor, thiab lub tshuab nqus tsev nqus tau ua tiav los ntawm kev ua haujlwm siab - lub tshuab nqus tsev twj, nrog lub zog noj ceev ntawm 0.28-0.35kWh / Nm³ O₂.Kev siv hluav taws xob raug txo los ntawm 30% -40%. Rau cov cuab yeej tsim tawm 10,000Nm³ ntawm cov pa oxygen ib hnub, VSA thev naus laus zis tuaj yeem txuag tau ntau dua ib lab RMB hauv cov nqi hluav taws xob txhua xyoo (raws li tus nqi hluav taws xob ntawm 0.8 RMB / kWh).
2. Oxygen Production Efficiency: Cov voj voog nrawm dua thiab muaj peev xwm hloov tau
PSA Technology: Lub sij hawm mus sij hawm ntev (60-90 vib nas this) ua rau txo qis zaus ntawm cov adsorption yees. Cov pa oxygen tso tawm ib chav tsev ntim ntawm molecular sieve yog kwv yees li 0.2-0.3Nm³ / (m³·h), thiab cov lus teb rau kev hloov pauv qeeb (yuav tsum tau ntau tshaj 30 feeb kom ruaj khov).
VSA Technology: Lub sij hawm voj voog luv luv rau 20-40 vib nas this, nce adsorption-desorption zaus. Cov pa oxygen tso tawm ib chav tsev ntim ntawm molecular sieve ncav cuag 0.4-0.6Nm³ / (m³·h),sawv cev rau kev txhim kho muaj peev xwm ntau dua 50%. Tsis tas li ntawd, nws muaj kev hloov pauv dav dav (30% -110%) thiab cov lus teb ceev ceev (stabilizing li ntawm 10 feeb), ua kom haum rau qhov xav tau oxygen dynamic hauv kev lag luam scenarios.
3. Cov Khoom Siv Lub Neej thiab Kev Saib Xyuas: Txhim khu kev ntseeg qis-Kev ua haujlwm siab
PSA Technology: Lub siab - ib puag ncig kev nyuaj siab adsorption yees, li qub, cov kav dej, thiab lwm yam khoom ua rau muaj kev ntxhov siab loj, ua rau muaj teeb meem xws li foob kev laus thiab khoom siv corrosion. Qhov nruab nrab txij nkawm lub voj voog yog kwv yees li 3-6 lub hlis, thiab kev pabcuam lub neej ntawm molecular sieves yog li 5-8 xyoo.
VSA Technology: Qhov qis -siab sib txawv tsim ntawm ze - atmospheric adsorption + nqus desorption txo cov khoom siv zog, txo qis hnav thiab ncua lub voj voog txij nkawm mus txog 12-18 lub hlis. Molecular sieves ua haujlwm nyob rau hauv cov mob me me, ua rau qeeb qeeb ntawm adsorption kev ua tau zoo thiab lub neej ua haujlwm ntev ntawm 8-12 xyoo.Cov nqi kho mob raug txo los ntawm 40% -60%.
4. Hneev taw thiab kev teeb tsa: tsim nyog rau cov xwm txheej sib txawv
PSA Technology: Yuav tsum muaj cov cuab yeej txhawb nqa xws li siab - compressors cua compressors thiab cua cia tso tsheb hlau luam. Tsis tas li ntawd, adsorption yees muaj cov phab ntsa tuab dua los tiv thaiv kev kub siab, ua rau tag nrho cov hneev taw 1.5-2 npaug ntawm VSA thev naus laus zis. Kev cob qha cov raj xa dej siab yuav tsum tau ua thaum lub sijhawm teeb tsa, nrog lub voj voog ntev (1-2 lub hlis).
VSA Technology: Tsawg- cov cuab yeej siv siab muaj cov qauv sib txuam ntau dua, nrog cov adsorption ntauwd phab ntsa tuab tsuas yog 1/3-1/2 ntawm PSA thev naus laus zis. Tsis xav tau lub tank loj loj, txo cov hneev taw los ntawm 30% -50%. Kev tsim cov kav dej tsis tas yuav tsum muaj kev tsim nyog siab, thiab lub voj voog kev teeb tsa tau luv rau 2-4 lub lis piam, ua rau nws tsim nyog rau kev txhim kho thiab kho dua tshiab ntawm lub Hoobkas nrog qhov chaw tsawg.
5. Oxygen Purity and Stability: Adapting to Wide-Range Requirements
PSA Technology: Cov pa purity ntau yog 90% -95%. Yuav kom ua tiav purity saum toj no 99%, yuav tsum muaj cov cuab yeej ua kom huv ntxiv, ua rau muaj kev siv zog ntau ntxiv (tshaj 30%).
VSA Technology: Cov pa purity tuaj yeem ncav cuag 93% -96%. Los ntawm optimizing molecular sieve formulations thiab voj voog tsis, high-purity oxygen tso zis ntau tshaj 99.5% yuav ua tau yooj yim, nrog ib tug purity fluctuation ntau yam tsawg dua los yog sib npaug rau ± 0.5%.Nws qhia tau hais tias kev siv hluav taws xob zoo dua nyob rau hauv siab -purity scenarios(txuag tshaj 25% zog piv rau PSA purification daws).
III. Complementary Application Scenarios (VSA Muab Kev Ua Tau Zoo Tshaj Plaws)
Ib txwm siv PSA thev naus laus zis yog qhov tsim nyog rau: me me - teev cov pa oxygen ntau lawm (txhua hnub tso zis tsawg dua lossis sib npaug li 5000Nm³), cov xwm txheej uas muaj qhov chaw txaus, thiab qhov xav tau oxygen ruaj khov (xws li cov tsev kho mob me, chav kuaj).
VSA thev naus laus zis yog qhov tsim nyog rau: Loj- nplai muaj cov pa oxygen ntau lawm (txhua hnub tso zis ntau dua lossis sib npaug li 5000Nm³), cov xwm txheej nrog cov pa oxygen hloov pauv, txwv qhov chaw, thiab tsom mus rau qhov ntev- kev ua haujlwm zoo tshaj plaws (piv txwv li, hlau thiab hlau smelting, tshuaj synthesis, iav manufacturing, loj{5}} chaw kho mob.
