2.1 Txheej Txheem Xaiv Rau Cov Khoom Ua Kua Ntau Lawm
1 luv luv piav qhia txog cov txheej txheem sib cais
Kuv lub teb chaws txoj kev sib cais thev naus laus zis muaj keeb kwm ntev ntawm kev txhim kho. Nyob rau hauv lub hnub thaum ntxov, cov txheej txheem feem ntau yog lub cryogenic sib sib zog nqus cov txheej txheem. Txawm li cas los xij, nrog kev txhim kho thev naus laus zis thiab cov txheej txheem tam sim no ntawm cov txheej txheem kev sib cais ntawm huab cua, Membrane Cais txheej txheem, thiab cov txheej txheem cryogenic distillation.
1.1 Siab viav vias Adsorption txheej txheem
Lub siab viav vias Adsorption txheej txheem feem ntau yog siv molecular sieves li adsorbents. Los ntawm kev hloov ntawm lub siab, cov nitrogen thiab oxygen lwg me me nyob rau hauv cov kev ua yeeb yam Tom qab ib ntus, kev sib cais ntawm cov nitrogen thiab oxygen molecules tuaj yeem ua tiav (, thiab tom qab ntawd cov pa nitrogen thiab oxygen lwg me me yog unloaded (siab viav txheej txheem). Cov molecular sab cib tuaj yeem siv rov qab ua tom qab kev tiv thaiv cov nitrogen thiab cov pa roj alchygen. Cov txheej txheem no ntawm adsorbing thiab tso cov nitrogen thiab oxygen lwg me me los ntawm molecular sieves thiab hloov lub siab yog hu ua "kev hloov pauv nrawm adsorption txheej txheem". Nyob rau hauv cov txheej txheem ntau lawm, huab cua huv yog yuav tsum tau tshem impurities nyob rau huab cua thiab xa nws mus rau lub buffer tank. Kev tsim kho cov txheej txheem ntawm cov siab viav vias Adsorption cov txheej txheem tsis nyuaj, tab sis qhov zoo ntawm cov tshuaj nitrogen thiab cov khoom muaj pa oxygen thiab cov khoom muaj pa tsawg.
1.2 Membrane Cais Txheej Txheem
Hauv txoj ntsiab cai, daim nyias nyias nyias siv lub hauv paus ntsiab lus sib txawv, raws li qhov sib txawv ntawm cov kev sib cais, cov kev sib txawv hauv cov neeg sib cais ntawm cov cua. Nws tsis yog qhov nyuaj kom pom tias kev ua tau zoo ntawm kev sib cais membrane txiav txim siab qib ntawm cov txheej txheem sib cais huab cua. Cov khoom siv raw ntawm ob sab ntawm daim nyias nyias, thiab ib feem nrog cov txiaj ntsig nrawm, nws tseem yuav dhau los ntawm cov txheej txheem ntau lawm, nws tseem yuav dhau los ntawm cov txheej txheem ua ntej ua ntej. Tus lej txiav sib cais yog qhov kev hloov pauv tau yooj yim ntawm txhua hom. Los ntawm hloov cov fiber ntau cov ntaub ntawv siv cov tshuaj ntxuav cov roj av, cov khoom lag luam roj ntawm ntau hom thiab kev ua raws cai tuaj yeem tau txais. Cov kev tshawb fawb tau pom tau pom tias qhov kev sib cais ntau dua los ntawm cov txheej txheem sib cais, cov kev tsim tawm ntau dua, yog li kev txhim kho ntawm cov kev tawm dag zog ntawm fiber ntau, yog li cov teeb meem tseem ceeb ntawm cov txheej txheem no.
1.3 tus txheej txheem distillation distillation
Cov txheej txheem cryogenic distillation yog ib qho kev hloov kho tshiab ntawm lub cryogenic tob ua dej txias cua. Nws lub hauv paus ntsiab lus yog siv cov khoom sib txawv ntawm cov nitrogen thiab oxygen lwg me nyob hauv huab cua. Oxygen lwg me me thiab nitrogen lwg me muaj ntau cov ntsiab lus boiling sib txawv. Cov huab cua yog thawj liquefied nyob rau hauv kev kub siab thiab tsawg kub, thiab tom qab ntawd distilled. Lub tshav kub hloov sib cais tau hloov mus rau hauv cov cua ua kua, yog li sib cais oxygen lwg me me thiab nitrogen molecules.
Tus txheej txheem no khaws ib txwm ntawm cov qauv ib txwm muaj nyob hauv cov ntawv thov tiag tiag, xws li cua compressors, cov tshuab tshav kub, tshuab tshav kub, thiab distillation systems. Piv nrog thawj ob txoj kev ua tiav, cov txheej txheem distillation distillation muaj cov yam ntxwv pom tseeb heev, nws tuaj yeem ua tiav cov khoom siv siab siab. Cov txheej txheem distillation distillation yog cuam tshuam los ntawm cov txheej txheem tshiab, feem ntau yog vim nws tus kheej cov txheej txheem nyuaj thiab tsis xws luag lub sijhawm pib. Tshwj xeeb, qhov tsis yooj yim tshwm sim los ntawm lub ntaus ntawv nws tus kheej, suav nrog huab cua compressors, suav nrog cov nqi peev txheej,
Txawm li cas los xij, nws yog undeniable hais tias nws yog tsis yooj yim sua kom tau txais high-purity nitrogen thiab cov khoom siv oxygen thiab chav sov) tseem tsis tseem ceeb.
2 xaiv cov txheej txheem txaus ntawm cov pa sib cais
Cov koog sib cais tau muaj ntau cov ntawv thov thiab muaj ntau hom. Cov kev lag luam sib txawv yuav tsum ua lawv tus kheej raws lawv tus kheej cov kev xav tau. Tom qab nkag siab txog cov ntsiab cai tseem ceeb ntawm cov pa sib cais, nws tseem yuav tsum txiav txim siab seb cov khoom lag luam twg (kua lossis roj xav tsim. Newtek tau ua cov lus pom zoo hauv qab no.
2.1 Txheej Txheem Xaiv Rau Cov Khoom Ua Kua Ntau Lawm
Cov ntaub ntawv raw sib raug rau cov pa sib cais thiab cov txheej txheem yog nyob rau hauv cov roj av, thiab kev kub siab, tsawg dua thiab lwm yam kev mob yuav tsum tau hloov mus rau hauv cov kua. Raws li cov yam ntxwv ntawm cov txheej txheem saum toj no, nws tsis yog qhov nyuaj rau txiav txim tias qhov tsawg-kub-distillation cov txheej txheem yog qhov zoo tshaj plaws kev xaiv kom tau txais cov khoom ua kua. Qhov no yog vim tias, nyob rau hauv tsis muaj qhov kev mob siab, txawm hais tias molecular siieve, nyob rau hauv cov pa roj carecen thiab oxygen molecules, nyob rau hauv cov pa roj carecen thiab oxygen molecranes tuaj yeem siv tau los yog 90.17K ({5}}. 98 degree). Lub qhov cub npau npau ntawm nitrogen (ntshiab nitrogen) yog 77.35K (-195. 80c). Nws yog tsis yooj yim sua kom tsim cov kua ua kua.
Yog li ntawd, kom tau txais cov khoom lag luam, kub yuav tsum tau txiav txim siab. Nyob rau tib lub sijhawm, cov txheej txheem cia ntawm cov kua ua kua kuj yog nruj heev heev, uas yuav tsum ua kom tiav cov docking nrog cov txheej txheem ntau lawm.
2.2 Txheej Txheem Xaiv Rau Gaseous Khoom Ntau Lawm
Cov txheej txheem ntau lawm ntawm gase cov khoom muaj ntau txoj kev xaiv. Ntxiv rau qhov tsis-cryogenic distillation cov txheej txheem, molecular sieves thiab kev sib cais cov tshuaj txhuam feem ntau siv. Ob cov txheej txheem tuaj yeem ua tiav cancol ntau lawm thiab txuag cov nqi. Txawm li cas los xij, qhov tsis zoo yog cov khoom lag luam nrog kev coj dawb huv siab dua. Txog qee cov khoom lag luam uas xav tau ntau dua, tag nrho cov kev sib cais muaj cua ntau dua-kub. Qhov laj thawj yog tias tseem muaj kev kos duab, kev sib cais thiab lwm yam kev kawm
tuaj yeem ua tiav lub hom phiaj ntawm huab cua sib cais, muaj cov kev tsis ncaj ncees ntuj (cov txheej txheem kev txwv) nyob rau hauv extraction ntawm kev ua kom siab siab. Cov tag nrho cov cua sib cais me me
3 Xaus
Los ntawm cov lus qhia saum toj no, Newtek tau tshuaj xyuas cov txheej txheem huab cua tseem ceeb. Ntawm ib sab tes, rov tshwm sim ntawm cov txheej txheem tshiab tau nce ntxiv cov zis ntawm cov txheej txheem sib cais, cov nqi cawm cov nqi thiab txhim kho kev ua tau zoo; Tab sis ntawm qhov tod tes, cov txheej txheem tshiab tsis tuaj yeem hloov cov txheej txheem ib txwm ua. Txhawm rau muab cov khoom lag luam siab, cov txheej txheem ib txwm muaj tseem muaj kev txhim kho cov kev cia siab. NewTek pab pawg yuav pib nrog cov txheej txheem kev txhim kho ntawm cov txheej txheem sib cais kom tau raws li qhov xav tau ntawm kev lag luam kev lag luam thiab ecology ib puag ncig.
