Khoom Description
Cryogenic kua oxygen tsob nroj (tseem hu ua cryogenic kua oxygen ntau lawm cov cuab yeej) yog ib tug loj - teev ua tiav cov cuab yeej tsim los ntawm lub hauv paus ntsiab lus ntawm cryogenic huab cua sib cais, nrog kua oxygen raws li cov khoom tseem ceeb.
Nws cov txheej txheem tseem ceeb yog kom compress, purify thiab txias txias, ces cais oxygen thiab nitrogen los ntawm ob-theem distillation, thiab thaum kawg liquefy lub cais siab - purity oxygen thiab khaws cia rau hauv ib qho qis - kub cia tank.
Nws tuaj yeem ua tsis tu ncua thiab ruaj khov ua tau siab -purity kua oxygen, thiab yog cov khoom siv tseem ceeb rau cov khoom loj - cov pa oxygen mov hauv kev lag luam thiab pej xeem.
Txoj cai ua haujlwm
Cov txheej txheem ua haujlwm ntawm cov nroj tsuag tau muab faib ua xya qhov txuas: cua compression → ua ntej - txias → purification → txias txias → distillation sib cais → oxygen liquefaction → kua oxygen cia & tso zis
Cua compression:Lub atmospheric cua yog nqus mus rau hauv cov cua compressor thiab compressed rau 0.6 ~ 1.2 MPa. Cov cua compressed yog txias los ntawm lub aftercooler kom tshem tawm cov cua sov uas tsim los ntawm compression, nteg lub hauv paus rau tom ntej no low-kub kev kho mob.
Cua ua ntej- cua txias:Cov cua compressed nkag mus rau hauv chav ua ntej- cua txias (suav nrog lub tshuab ua kom txias thiab lub tub yees). Cov huab cua kub yog txo mus rau 5 ~ 10 degree, thiab feem ntau ntawm cov dej noo nyob rau hauv cov huab cua yog condensed rau hauv dej tee dej thiab sib cais, txo cov load ntawm lub tom ntej purification system.
Cua purification:Lub ua ntej- cua txias nkag mus rau ob -ntauwd adsorption purification system (pw nrog molecular sieve). Cov molecular sieve adsorbs thiab tshem tawm impurities xws li residual noo noo (cov ntsiab lus Tsawg dua los yog sib npaug rau 0.1 ppm), carbon dioxide (cov ntsiab lus tsawg dua los yog sib npaug rau 0.1 ppm) thiab hydrocarbons (cov ntsiab lus tsawg dua los yog sib npaug rau 0.01 ppm) nyob rau hauv cov huab cua kom tsis txhob khov thiab thaiv cov khoom qis {{6} xws li explosion thiab hatemperion. tshwm sim los ntawm hydrocarbon tsub zuj zuj.
Kev sib sib zog nqus cua txias:Cov huab cua huv huv nkag mus rau hauv lub tshuab hluav taws xob tseem ceeb thiab sib pauv cov cua sov nrog qhov qis -kub reflux gas (nitrogen, oxygen-cov roj nplua nuj) los ntawm ntauwd distillation. Cov huab cua kub yog maj mam txo los ntawm ib txwm kub mus rau ze liquefaction kub (-170 ~ -175 degree), thiab ib feem ntawm cov huab cua yog liquefied.
Distillation sib cais:Cov cua liquefied ib nrab nkag mus rau ob-theem distillation ntauwd (tsawg pej thuam: siab- siab ntauwd, kev khiav hauj lwm siab 0.5 ~ 0.6 MPa; lub siab tshaj: qis- siab ntauwd, kev khiav hauj lwm siab 0.12 ~ 0.15 MPa):
● Tsawg ntauwd distillation: Cov huab cua sib cais rau hauv oxygen- huab cua nplua nuj ua kua (oxygen ntsiab lus txog 38 ~ 40%) thiab crude nitrogen (nitrogen purity txog 95 ~ 98%) los ntawm ntau yam evaporation thiab condensation. Cov roj nitrogen yog rub los ntawm sab saum toj ntawm cov pej thuam qis thiab nkag mus rau lub ntsiab cua kub hloov pauv rau reheating, thiab ib feem ntawm nws yog siv los ua cov roj regeneration rau molecular sieve;
● Upper tower distillation: Cov pa oxygen- huab cua nplua nuj yog throttled thiab txo mus rau saum pej thuam, thiab ntxiv distillation yog ua. High-purity oxygen (purity Ntau dua lossis sib npaug li 99.6%) tau txais nyob rau hauv qab ntawm cov pej thuam sab sauv, thiab cov nitrogen ntshiab (purity Ntau dua lossis sib npaug li 99.999%) yog tau nyob rau saum toj siab (raws li ib qho los ntawm - khoom).
Oxygen liquefaction:Lub siab -purity oxygen nyob rau hauv qab ntawm lub tsev siab tshaj yog muab faib ua ob qhov chaw: ib feem nkag mus rau lub condenser- evaporator nyob rau hauv lub hauv qab ntawm lub qis pej thuam, exchanges tshav kub nrog cov kua nitrogen los ntawm lub hauv qab pej thuam, yog liquefied rau hauv cov kua oxygen (kub -183 degree) thiab ntws rov qab mus rau hauv qab ntawm lub sab sauv pej thuam li reflux kua. lwm qhov yog kos tawm raws li cov pa oxygen, nkag mus rau hauv cov kua oxygen condenser, thiab yog txias thiab liquefied los ntawm qhov kub-kub nitrogen los ntawm cov pej thuam saum toj kom tau cov khoom ua kua oxygen.
Ua kua oxygen cia & tso zis:Cov kua pa oxygen yog khaws cia rau hauv qhov qis -kub ua kua oxygen cia tank (tso los ntawm lub tshuab nqus tsev vacuum, nrog cov evaporation txhua hnub tsawg dua lossis sib npaug li 0.3%). Thaum cov zis xav tau, cov kua oxygen yog nias tawm ntawm lub tank los ntawm cov kua oxygen twj tso kua mis, thiab tuaj yeem xa ncaj qha mus rau tus neeg siv qhov qis - kub cia tank los ntawm cov kua oxygen tanker, los yog vaporized rau hauv gaseous oxygen los ntawm lub vaporizer thiab ces muab rau tus neeg siv raws li qhov yuav tsum tau ua.
