PSA (Pressure Swing Adsorption) thiab VSA (Nqus Siab Viav Adsorption) oxygen generators yog qhov tseem ceeb ntawm -site oxygen production technologies. Lawv cov nqi sib txawv nyob ntawm seb cov yam ntxwv ntawm kev ua haujlwm, daim ntawv thov scenarios thiab ntev - cov nqi ua haujlwm. Kab lus no sib piv lawv cov nqi los ntawm peb qhov tseem ceeb los qhia kev txiav txim siab yuav khoom.
1. Kev sib piv tus nqi pib nqis peev
Kev nqis peev thawj zaug yog qhov sib txawv tseem ceeb: PSA pheej yig dua rau cov dej me me thiab nruab nrab, thaum VSA xav tau kev nqis peev ntau dua tab sis yog tus nqi - zoo rau cov dej ntws loj.Liandong VSA oxygen tsim technologysawv tawm nrog qis- roj siab-dawb tsim thiab lub zog-txuag qhov zoo, cuam tshuam rau VSA cov nqi khoom thiab cov nqi ua haujlwm.
1.1 PSA Oxygen Generator
Nrog cov qauv compact thiab yooj yim muaj pes tsawg leeg, PSA muaj qis pib peev:
Me - nplai (1 ~ 30 LPM): $ 100 ~ $ 3,500 (piv txwv li, 5L kho mob qauv: $ 589 ~ $ 655).
Nruab nrab- nplai (30 ~ 500 Nm³ / h): $ 3,600 ~ $ 300,000, haum rau cov neeg siv nrog cov nyiaj pib tsawg thiab cov kev xav tau yooj yim.
1.2 VSA Oxygen Generator
VSA xav tau lub tshuab nqus tsev twj thiab zaus hloov tshuab tshuab, nrog kev nqis peev ntau dua:
Me-scale (Ntau dua lossis sib npaug rau 500 Nm³ / h): Pib txij li $45,000.
Loj -scale (Ntau dua lossis sib npaug ntawm 1000 Nm³ / h): $ 200,000 ~ $ 800,000. Liandong VSA qauv yog 5 ~ 10% siab dua ($ 210,000 ~ $ 850,000) vim kev siv thev naus laus zis (xws li cov qauv kev kho mob hauv cheeb tsam: $ 630,000 ~ $ 820,000).
VSA thawj zaug peev yog 1.5 ~ 2 npaug ntawm PSA rau tib qhov dej ntws loj, tab sis Liandong VSA txo cov nqi ntev -cov nqi zais nrog qis- roj siab- qauv tsim dawb, kev tswj lub suab nrov (≈70dB) thiab ua ntej - theem kev ua haujlwm ntawm lub zog.
2. Kev sib piv tus nqi ua haujlwm thiab kev saib xyuas
PSA muaj O&M cov nqi siab dua, thaum VSA tus nqi ntau dua - siv tau rau lub sijhawm ntev, tshwj xeeb tshaj yog rau kev khiav lag luam loj.
2.1 PSA Oxygen Generator
Kev siv hluav taws xob: 0.6 ~ 0.8 kWh / Nm³; tus nqi hluav taws xob txhua hli siab rau kev ua haujlwm 24-teev.
Consumables: Molecular sieve kev pab cuam lub neej 2 ~ 3 xyoos; Kev hloov cov lim dej tsis tu ncua ua rau cov nqi nce ntxiv.
Kev tu ntau zaus vim muaj kev kub ntxhov, nce nqi zog.
2.2 VSA Oxygen Generator
Kev siv hluav taws xob: 0.4 ~ 0.6 kWh / Nm³ (10 ~ 25% zog txuag vs PSA). Liandong VSA txuag ib qho ntxiv 5 ~ 10% (0.35 ~ 0.55 kWh / Nm³) nrog lub tshuab nqus tsev nitrogen tso tawm.
Consumables: LiX molecular sieve kev pab cuam lub neej 5 ~ 7 xyoo; Liandong VSA ncua nws mus rau 6 ~ 8 xyoo, txo cov nqi khoom siv txhua xyoo los ntawm 15 ~ 20%.
Tsawg txij nkawm vim nyob ze - huab cua siab ua haujlwm thiab ruaj khov siab.
3. Unit Oxygen Production Cost Comparison
PSA: $ 0.01 ~ $ 0.02 / Nm³, tsim nyog rau kev thov oxygen me me.
VSA: $0.003 ~ $0.008/Nm³; Liandong VSA txo nws mus rau $ 0.0025 ~ $ 0.007 / Nm³, offsetting ntau dua pib peev hauv 1.5 ~ 2.5 xyoo rau cov neeg siv loj - nplai.
4. Cov ntsiab lus tseem ceeb cuam tshuam rau tus nqi sib txawv
Oxygen purity: Ntau dua lossis sib npaug rau 99% purity nce nqi los ntawm 10 ~ 30%.
Hom: Zoo-cov npe nrov (piv txwv li, Pentair AES, JSMINNUO, Liandong Medical) muaj tus nqi siab dua. Liandong VSA muab 1-xyoo dawb warranty thiab kev tu lub neej, nrog cov khoom siv hauv ntau tshaj 1000 lub tsev.
Customization: Cov qauv kev cai (khoom- hom, siab- qhov siab hloov kho) nce nqi los ntawm 15 ~ 40%.
Tom qab- kev muag khoom: Ntev- lub sij hawm lav me ntsis nce nqi tab sis txo cov kev pheej hmoo ntawm kev saib xyuas.
