Pressure Swing Adsorption (PSA) oxygen tsim yog ib qho zoo -tsim technology nyob rau hauv industrial oxygen mov. Containerized designs tau txais txiaj ntsig zoo heev vim tias lawv muab tag nrho cov txheej txheem rau hauv cov thawv ntim khoom txheem, ua rau kev thauj mus los, nqa, thiab qhov chaw teeb tsa yooj yim dua li cov tsoos tsoos -mounted lossis site- ua cov chav cog. Hais tias, "containerized" tsis tau txhais hais tias "tuaj yeem muab tso rau qhov twg yam tsis xav." Yog tias kev xaiv tsuas yog tsom rau qhov tso zis ntim thiab purity thaum saib xyuas qhov chaw, kev hloov pauv ib puag ncig, thiab kev siv hluav taws xob, cov teeb meem feem ntau tshwm sim hauv txoj kev.
Phau ntawv qhia no mus txog qhov kev kawm los ntawm kev ua haujlwm thiab kev ua haujlwm - engineering foundations, piav qhia txog qhov loj me uas tsim nyog tau txais kev saib xyuas thaum xaiv lub thawv PSA oxygen generator.
Tsis txhob Pib nrog Kev Ntsuas Cov Khoom Siv -Pib nrog Kev Xav Tau tiag
Ntau qhov haujlwm ntau dhau ntawm kev ntsuas cov pa oxygen tso tawm los ntawm hnub ib. Tab sis qhov kev siv tiag tiag tsis tshua ua raws li txoj kab ncaj nraim -peaks thiab hav yog qhov qub. PSA cov tshuab tuaj yeem nce lossis nqis, tab sis yuav ua li cas zoo thiab ceev npaum li cas nyob ntawm lub nkoj tsim, qhov kev teeb tsa valve, thiab tswj cov logic.
Yog li pib nrog qhov xav tau profile. Nug: tsis tu ncua lossis tsis sib xws? Ntev npaum li cas lub sij hawm ncov siab? Puas muaj qhov chaw tos txais -zoo li cov pa oxygen- los npog cov surges? Cov lus teb no txhawb nqa qhov loj me thiab txhawb cov khoom siv. Xaiv ib chav tsev uas tsuas zoo li "loj txaus" feem ntau backfires.
Ntawm purity: feem ntau PSA units xa 90-95% tawm ntawm lub thawv. Yog tias koj xav tau 99% lossis siab dua, npaj rau kev ntxiv lub tshuab lim dej lossis hloov tshuab. Tsis tas li ntawd, purity thiab ntws pauv tawm - siab dua purity txhais tau tias tsawg dua cov khoom tawm los ntawm tib lub skid. Teem koj lub hom phiaj purity kom phim cov txheej txheem tiag tiag xav tau, tsis yog tus lej puag ncig uas suab zoo.
Containerized PSA Systems: Site Adaptability Matters Ntau tshaj qhov koj xav
Cov txiaj ntsig pom tseeb ntawm cov thawv ntim PSA yog kev sib koom ua ke-cov khoom siv adsorbers, piping, li qub, compressor, tshuab ziab khaub ncaws, thiab tswj txhua qhov ntim rau hauv ib lossis ob lub thawv ntim khoom txheem. Qhov ntawd txhais tau hais tias qhov chaw ua haujlwm tsawg dua, kev teeb tsa sai dua, thiab kev sib koom ua ke tsawg dua.
Tab sis tus nqi tiag tiag tsis yog lub thawv - nws yog qhov zoo npaum li cas lub thawv ntawd tuav qhov chaw nws tso. Peb qhov chaw- tej yam tshwj xeeb yuav tau txais glossed:
- Ambient kub. Lub compressor thiab tshuab ziab khaub ncaws ua kom muaj cua sov tseem ceeb hauv qhov chaw nruj. Nyob rau hauv huab cua kub, passive convection yuav tsis txiav nws - yuam cua cua los yog cua txias tej zaum yuav tsum tau. Yog tias tus qauv tsim tsis haum rau qhov chaw lub caij ntuj sov peaks, kev ua haujlwm yuav raug kev txom nyem.
- Qhov siab. PSA efficiency poob nrog qis atmospheric siab. Tshaj 500 meters, cov zis nkhaus yuav tsum tau kho. Tsis quav ntsej qhov no, thiab lub kaw lus yuav tsis xa nws cov nqi ntsuas - yooj yim li qhov ntawd.
- Huab cua thiab corrosion. Tsis yog txhua lub thawv muaj tib theem ntawm kev sib khi lossis txheej. Cov ntug dej hiav txwv lossis qhov chaw ntub dej xav tau cov ntaub ntawv zoo dua, cov xim tawv dua, thiab cov khoom siv hluav taws xob ntau dua. Rau kev teeb tsa sab nraum zoov xav kom kav ntev, IP54 yuav tsum tau saib raws li hauv pem teb, tsis yog lub qab nthab.
Tau txais cov cai no ua ntej, thiab lub thawv xa khoom raws li nws cov lus cog tseg. Nco lawv, thiab koj tab tom kho cov teeb meem tom qab lub crane tawm lawm.
Huab cua Pretreatment - Qhov tseem ceeb txuas feem ntau saib xyuas
Cov hlab ntsha adsorber yog lub plawv ntawm txhua qhov PSA system, tab sis adsorbent lub neej thiab kev ua haujlwm ruaj khov nyob ntawm qhov zoo ntawm cov cua nkag. Roj, noo noo, thiab cov khoom me me uas tau nqa los ntawm cov cua compressed maj mam kis tus kab mob molecular sieve, txo qhov muaj peev xwm adsorption, ua rau purity fluctuations, thiab qee zaum yuav tsum tau hloov ntxov ntxov ntawm cov adsorbent.
Lub thawv ntim cov txheej txheem cua pretreatment tsheb ciav hlau feem ntau suav nrog:
- Cua compressor (ntsia hlau lossis piston hom, nyob ntawm qhov ntsuas)
- Txias tshuab ziab khaub ncaws
- Multi-stage filtration (roj tshem tawm, tshem tawm cov khoom)
Thaum xaiv, paub meej tias lub peev xwm pretreatment sib phim tus nqi xa khoom compressor thiab qhov kev saib xyuas niaj hnub no -xws li lim cov hloov pauv thiab cov kua dej condensate - tuaj yeem ua tau yooj yim hauv qhov chaw ntim khoom. Qee cov qauv tsim ua ke ua ke ua ntej hauv tib lub thawv raws li cov adsorbers; lwm tus muab tso rau hauv ib lub thawv cais. Lub qub qub muaj ib tug hneev taw me me tab sis feem ntau txi ua hauj lwm clearance thiab cua kub dissipation, yog li ntawd muaj kev lag luam -offs los luj.
