Lub tshuab hluav taws xob oxygen yog ib qho cuab yeej uas rho tawm thiab tsim cov pa oxygen los ntawm cov pa roj (feem ntau yog huab cua nyob ib puag ncig) los ntawm cov txheej txheem ntawm lub cev lossis tshuaj lom neeg, tsis tas yuav tsum tau ua ntej - cov pa oxygen cylinders. Nws lub luag haujlwm tseem ceeb yog cais thiab mloog cov pa oxygen los ntawm lwm cov khoom hauv huab cua, xa ib qho chaw ruaj khov, ntawm - xav tau cov pa oxygen nrog cov ntsiab lus purity rau kev siv ntau yam xwm txheej. Piv nrog cov pa tso tsheb hlau luam uas yuav tsum tau rov ua dua lossis hloov pauv, cov tshuab hluav taws xob oxygen muab cov kev daws teeb meem oxygen yooj yim dua thiab ruaj khov.
Cov ntsiab cai ua haujlwm tseem ceeb
Feem ntau ntawm kev lag luam thiab tsev neeg cov pa oxygen generators ua haujlwm raws li covSiab Swing Adsorption (PSA)technology, uas yog ib txoj kev sib cais lub cev:
Cua nkag thiab pom: Cov cuab yeej ua ntej kos rau hauv cov huab cua puag ncig thiab hla nws los ntawm lub lim kom tshem tawm cov plua plav, noo noo, roj, thiab lwm yam impurities, kom ntseeg tau tias huab cua nkag mus rau hauv kev sib cais yog huv si.
Compression: Cov cua lim yog compressor los ntawm compressor kom nws siab, uas yuav pab txhim kho efficiency ntawm cov pa sib cais.
Adsorption thiab Sib cais: Cov cua compressed yog ces coj mus rau hauv ib kem uas muaj cov khoom tshwj xeeb adsorbent (feem ntau molecular sieve, xws li zeolite). Molecular sieves muaj kev sib raug zoo rau nitrogen molecules (qhov tseem ceeb ntawm huab cua, suav txog li 78%) thiab yuav adsorb nitrogen, thaum tso cai rau oxygen molecules (kwv yees li 21% hauv huab cua) dhau mus. Cov txheej txheem no tsim cov pa oxygen nrog qib purity xws li 90% mus rau 95% (nyob ntawm lub cuab yeej).
Kev Tshaj Tawm thiab Kev Txhim Kho: Thaum lub molecular sieve nyob rau hauv ib kem tau saturated nrog nitrogen, lub kaw lus hloov mus rau lwm kem (feem ntau PSA generators muaj ob kab rau kev ua hauj lwm tas mus li) mus txuas ntxiv ua pa. Cov kab saturated ces tso siab, tso cai rau cov adsorbed nitrogen rau desorb thiab raug tso tawm rau hauv huab cua, regenerating molecular sieve rau rov siv dua. Qhov no cyclic "adsorption-regeneration" txheej txheem ua kom cov pa oxygen tsis tu ncua.
Lwm yam khoom siv hluav taws xob tsawg dua tuaj yeem siv cov tshuaj tiv thaiv (piv txwv li, oxygen- tsim cov tshuaj uas tso tawm cov pa thaum ua haujlwm) lossis cov tshuab sib cais membrane (siv semi-permeable membrane cais oxygen los ntawm huab cua), tab sis cov no feem ntau yog siv rau cov me me - teev lossis xwm txheej xwm txheej ceev.
Main Hom thiab Daim Ntawv Thov
1. Tsev neeg Oxygen Generators
Cov tshuab hluav taws xob hauv tsev yog compact thiab yooj yim rau kev khiav lag luam, tsim los siv hauv tsev. Lawv feem ntau muaj cov hneev taw me me thiab tsis tshua muaj suab nrov, nrog cov pa oxygen txaus ntawm 1-5 litres ib feeb (LPM) thiab purity li ntawm 90% mus rau 95%. Cov xwm txheej ntawm daim ntawv thov feem ntau suav nrog:
Muab cov pa oxygen ntxiv rau cov neeg laus los pab tswj cov ntshav oxygen hauv cov ntshav thiab txhawb nqa lub cev muaj zog txhua hnub.
Cov pa oxygen ntxiv rau cov neeg laus los txhim kho cov ntshav oxygen thiab txhim kho lub cev muaj zog.
Kev siv cov pa oxygen ntxiv thaum lub sij hawm rov qab los ntawm kev mob lossis kev phais, nrog rau kev ua kom qaug zog los ntawm qhov siab - qhov chaw siab, kev ua haujlwm hnyav lossis kev kawm (nco tseg: qhov no yog rau kev saib xyuas kev noj qab haus huv thiab kev qaug zog, tsis yog rau kev kho mob).
2. Kev Kho Mob Oxygen Generators
Kev kho mob oxygen generators yog siab - cov khoom siv ua tau raws li cov qauv kev kho mob nruj (xws li ISO, FDA certifications). Lawv tuaj yeem tsim cov pa oxygen nrog qhov purity ntau dua lossis sib npaug li 93% (ua tau raws li cov qauv kev kho mob oxygen) thiab cov nqi ntws ntau dua (txog 10-20 LPM). Lawv tau siv dav hauv tsev kho mob, chaw kho mob thiab xwm txheej xwm txheej ceev, suav nrog:
Muab cov pa oxygen rau cov neeg mob thaum lub sijhawm phais, tshuaj loog, lossis kev kho mob tseem ceeb (xws li, hauv cov chaw kho mob hnyav (ICUs)).
Kho mob ua pa nyuaj (piv txwv li, mob ntsws, ua pa tsis ua haujlwm) uas yuav tsum tau muaj siab - kev txhawb nqa oxygen purity.
Muab cov pa oxygen rau cov kev pab kho mob xwm txheej ceev (xws li tsheb thauj neeg mob) kom ruaj khov rau cov neeg mob thaum lub caij tsheb thauj mus los.
3. Muaj Oxygen Generators
Cov tshuab hluav taws xob muaj hluav taws xob muaj qhov loj - nplai, siab - lub tshuab muaj peev xwm, tsim nyog rau cov txheej txheem tsim khoom lag luam uas xav tau ntau cov pa oxygen. Lawv tuaj yeem tsim cov pa oxygen nrog qib purity sib txawv (90% txog 99.99%) thiab cov nqi ntws los ntawm ntau pua mus rau txhiab cubic meters ib teev twg. Cov xwm txheej ntawm kev thov ib txwm muaj xws li:
Kev ua hlau (piv txwv li, oxygen- ua kom muaj kev sib xyaw ua ke hauv steelmaking, txiav, thiab vuam los txhim kho kev ua haujlwm thiab txo kev siv hluav taws xob).
Kev lag luam tshuaj (piv txwv li, raws li cov khoom siv raw rau tshuaj lom neeg xws li oxidation, fermentation, thiab synthesis).

Aerospace thiab dhia dej (xws li, muab cov pa oxygen rau cov dav hlau cabins, cov khoom siv dhia dej, thiab kev ua haujlwm siab -qhov siab).
Qhov Zoo Tshaj Plaws
Kev Txuas Txuas Ntxiv: Sib txawv ntawm cov thooj voos kheej kheej uas muaj peev xwm tsawg, cov tshuab hluav taws xob oxygen tuaj yeem tsim cov pa tsis tu ncua thaum siv hluav taws xob thiab nkag mus rau huab cua.
Kev yooj yim thiab kev nyab xeeb: Lawv tshem tawm qhov xav tau ntawm kev thauj mus los, rov ua dua, lossis khaws cia siab - lub tog raj kheej oxygen siab, txo qhov kev pheej hmoo ntawm kev tawg lossis tawg cuam tshuam nrog kev siv lub tog raj kheej.
Tus nqi Efficiency: Rau cov neeg siv nrog ntev - lub sij hawm oxygen xav tau, oxygen generators zoo li yuav pheej yig dua kev yuav cov pa oxygen cylinders nyob rau hauv lub sij hawm ntev.
Environmental Friendliness: Feem ntau cov tshuab hluav taws xob oxygen (tshwj xeeb yog hom PSA) tsis tsim teeb meem los ntawm - cov khoom, vim tias cov nitrogen sib cais tau ncaj qha tso rov qab rau hauv huab cua, ua rau lawv cov tshuaj ntsuab.
Cov ntsiab lus
Hauv cov ntsiab lus, lub tshuab hluav taws xob oxygen yog lub tshuab hluav taws xob sib cais uas rho tawm thiab mloog cov pa oxygen los ntawm huab cua lossis lwm qhov chaw los ntawm cov txheej txheem tshawb fawb. Vim nws qhov zoo ntawm cov khoom siv tas mus li, yooj yim, kev nyab xeeb thiab tus nqi siv tau, nws tau dhau los ua cov cuab yeej siv dav hauv kev kho mob, kev saib xyuas hauv tsev thiab kev lag luam. Kev xaiv lub tshuab hluav taws xob oxygen yuav tsum ua raws li cov txheej txheem thov tshwj xeeb, suav nrog kev xav tau oxygen purity, ntws tus nqi thiab ib puag ncig siv.
