Cov pa nkev hluav taws xob tsob nroj

Nws ua haujlwm li cas

●Siab viav vias Adsorption (Psa) Txuj

Tom qab -}} kev kho thiab kev tshem tawm tshem tawm, huab cua nkag mus hauv cov adsorption ntauwd. Nyob rau hauv ib lub siab ntawm 0.6-0.8 MPa, cov molecular sab cib nqus cov pa nqus dej nitrogen, thiab cov pa (90% -99.5% purity) tau sau thiab tso zis. Tom qab adsorption saturation, lub siab yog txo thiab ua kom tau dua tshiab, siv ntau tus yees nyob rau lwm lub tsheb mus los ua kom tiav kev siv oxygen.

●Cryogenic Distillation Txuj Ci

Huab cua yog nias (0.5 -}}} → → ua ntej txias rau -170 degch nyob rau hauv lub ntsiab kev hloov pauv rau liquefaction. Cov huab cua tau nkag mus rau lub pej thuam distillation, uas cov pa (-183 degree) thiab muaj peev xwm sib cais los ntawm cov pej thuam hauv qab thiab tuaj yeem tso tawm raws li cov roj lossis muab tso rau ntawm daim ntawv liquefied.

●Membrane Sib Cais Qauv

Pretreated compressed huab cua (0.3-0.5 MPa) tau pub rau hauv hollow fiber membrane module. Oxygen Permeates sai (3-5 zaug uas ntawm nitrogen) los ntawm daim nyias nyias, yielding 30% -90% cov pa ntshiab. Nitrogen yog khaws cia thiab tso tawm nrog lub pa. Kev tswj hwm siab thiab ntws tawm tuaj yeem siv los kho qhov huv thiab tawm los.

●Tshuaj lom neeg pa yeeb yam khoom

Oxygen -} Muaj cov ntsiab lus (xws li sodium pectening thiab sodium peroxide) deciumen, lossis dej, sodium chlorate yuav tsum muaj 250-300℃nrog mnoos). Cov pa oxygen yog qhov tso zis ntawm tus nqi txaus. Hom no yog tsim nyog rau cov xwm txheej kub ntxhov thiab yuav tsum tau hloov cov ntaub ntawv raw.
 

Dab tsi yog cov pa hluav taws xob cog, thiab nws txawv li cas los ntawm cov pa oxygen?
Nws yog qhov loj - nplai zog tsim high {{1} {{1} {{1} {1} { Cov neeg hauv tsev neeg cov ntsiab lus yog me ({{5} {% purity) rau kev kho mob rau tus kheej / kev saib xyuas kev noj qab haus huv me thiab yooj yim dua.
 

Dab tsi yog cov ntsiab lus tseem ceeb ntawm cov pa roj teeb, thiab siv dav?
Peb cov ntsiab cai tseem ceeb rau kev sib cais oxygen los ntawm huab cua:
PSA: Siv Adsorbents cais cov n₂ / o₂ ntawm lub siab pauv; Cauj pib -} li, tsawg zog, rau nruab nrab- ntsuas kev xav tau.
Qis - kub distillation: liquefies huab cua, cais tawm ntawm kev npau taws me ntsis; Muaj siab dawb huv (txog li 99.999%), tso zis loj, rau loj- nplai kev lag luam.
Membrane sib cais: siv cov plaub hau permebranes; low purity (30% - 50%), small output, for low - demand scenarios.
Siv dav siv: PSA thiab qis - kub distillation.

Dab tsi cov teeb meem tseem ceeb thaum xaiv cov pa hluav taws xob cog?

Kev thov: Tshaj tawm cov sijhawm teev cov qhab nia thiab kev ua kom dawb huv (muaj: 95%- 99.5}}}}}}}}}
Tus nqi: Sib piv kev siv hluav taws xob (hluav taws xob rau PSA, ntuj roj rau distillation) kom tswj tau ntev {}} cov nqi siv.
SITE: Ua kom muaj chaw txaus thiab txhawb nqa cov chaw (fais fab, dej).
Kev ntseeg tau: Xaiv cov khoom siv ruaj khov (piv txwv li, dual - portters nrog zoo tom qab {3} kev muag khoom.

Yuav ua li cas kev ntsuas kev nyab xeeb uas xav tau rau cov oxygen tshuab cog?
Cov kauj ruam kev nyab xeeb tseem ceeb:
Kev Tiv Thaiv Hluav Taws / tawg: Tsis muaj qhib nplaim taws hauv thaj chaw; Siv oxygen - siv cov ntaub ntawv tshaj (stainless hlau) rau cov kav dej, thiab cov kav dej tshiab / derust, cov kav dej tshiab.
Kev Ntsuam Xyuas: Nruab O₂ cov kev ntsuas pom thiab kev ntsuas siab; Lub tswb thiab Nres ua haujlwm yog tias muaj nqi yog txawv txav.
Kev Txij Nkawm: Tsis tu ncua huv si / hloov Psa Adsorbents, Kuaj cov kaw lus Distillation nruj nreem, thiab cov neeg qhia ua haujlwm ntawm kev kub ceev.
Cia / Thauj: Chaw tso tsheb hlau luam hauv ventilated, chaw txias kom deb ntawm flammables; Siv cov tsheb tshwj xeeb rau kev thauj.
 

Dab tsi yog cov qauv yav tom ntej ntawm cov pa hluav taws xob cov nroj tsuag?

Lub zog siab dua: Tsim zog - kev txuag tech thiab siv lub zog txuas ntxiv mus txiav cov pa roj carbon emissions txuas ntxiv.
Modular tsim: Prefabricate Cheebtsam rau nrawm rau -}}}} chaw sib dhos; Kho cov zis ntawm modules.
Digitalization: Siv ITOT / Ai rau tiag {{0} Lub sijhawm ua ntej soj ntsuam, thiab kev ua txhaum kev ua txhaum.
Cov ntaub ntawv nthuav tawm: nthuav dav rau hydrogen zog (co-}}}}}}}) thiab kev nrhiav chaw (me me, cov khoom siv tau zoo rau cov astronoms).
