Cryogenic huab cua sib cais tshuab yog ib txoj hauv kev tseem ceeb rau kev tsim cov nitrogen thiab oxygen hauv kev lag luam niaj hnub no. Cov tshuab no tau siv dav hauv ntau yam lag luam xws li metallurgy, chemical engineering, thiab tshuaj. Tsab ntawv xov xwm no yuav tshawb nrhiav tob txog yuav ua li cas cryogenic huab cua sib cais ua rau muaj siab purity nitrogen thiab oxygen, nrog rau cov kauj ruam tseem ceeb thiab cov khoom siv koom nrog hauv cov txheej txheem.

1. Lub hauv paus ntsiab lus ntawm cryogenic cua sib cais

Cryogenic huab cua sib cais yog txheej txheem uas cais cov khoom tseem ceeb ntawm huab cua los ntawm kev txo qhov kub. Cua tsuas yog muaj nitrogen, oxygen, thiab ib qho me me ntawm argon. Los ntawm compressing thiab txias huab cua mus rau qhov tsis tshua muaj kub, huab cua yog liquefied, thiab ces qhov sib txawv boiling ntsiab lus ntawm txhua roj yog siv rau distillation cais nitrogen thiab oxygen. Qhov kub ntawm nitrogen yog -195.8 ℃, thiab cov pa oxygen yog -183 ℃, yog li lawv tuaj yeem ua kom huv si sib cais los ntawm cov txheej txheem distillation.

2. Kev kho mob ua ntej: Cua purification

Hauv cov txheej txheem kev sib cais huab cua cryogenic, kev kho cua ua ntej yog thawj kauj ruam tseem ceeb. Cua muaj impurities xws li plua plav, carbon dioxide, thiab ya raws, uas yuav khov nyob rau hauv ib puag ncig uas tsis kub, ua rau cov khoom thaiv. Yog li ntawd, huab cua yog thawj zaug pom, compression, thiab ziab cov kauj ruam kom tshem tawm impurities thiab ya raws. Feem ntau, cov tshuab ziab khaub ncaws thiab molecular sieve adsorbers yog cov cuab yeej tseem ceeb siv los tshem tawm cov impurities ntawm huab cua, ua kom muaj kev ruaj ntseg thiab ua haujlwm ntawm cov txheej txheem sib cais cryogenic tom qab.

3. Cua compression thiab txias

Cov cua purified yuav tsum tau compressed, feem ntau yog los ntawm ntau lub compressors kom lub siab ntawm huab cua mus rau 5-6 megapascals. Cov cua compressed ces txias los ntawm tshav kub exchangers nrog cov roj rov qab los ntawm qhov kub thiab txias, maj mam txo qhov kub kom mus txog qhov liquefaction point. Hauv cov txheej txheem no, cov khoom siv hluav taws xob sib hloov ua lub luag haujlwm tseem ceeb, vim tias lawv tuaj yeem txo qis kev siv hluav taws xob thiab txhim kho kev ua kom txias, kom ntseeg tau tias huab cua tuaj yeem ua kua dej hauv qhov kub thiab txias, muab cov xwm txheej rau kev sib cais tom qab distillation.

4. Cua liquefaction thiab distillation

Nyob rau hauv lub cryogenic sib cais ntauwd, cov cua compressed thiab txias yog ntxiv txias rau lub xeev liquefied. Cov huab cua liquefied raug xa mus rau ntauwd distillation rau kev sib cais. Lub distillation ntauwd tau muab faib ua ob ntu: lub siab-siab ntauwd thiab lub siab-siab ntauwd. Nyob rau hauv lub siab-siab ntauwd, cov huab cua yog sib cais rau hauv crude oxygen thiab crude nitrogen, thiab ces cov crude oxygen thiab crude nitrogen yog ntxiv distilled nyob rau hauv lub low-pressure pej thuam kom tau high-purity oxygen thiab nitrogen. Kev sib cais ntawm nitrogen thiab oxygen feem ntau yog siv lawv lub cev sib txawv ntawm cov ntsiab lus kub, yog li kev sib cais muaj peev xwm ua tiav hauv ntauwd distillation.

5. Kev ua kom huv huv

Cov pa oxygen thiab nitrogen sib cais nyob rau hauv lub distillation ntauwd tseem muaj me me ntawm impurities, yog li lawv yuav tsum tau ua kom huv ntxiv kom tau raws li cov qauv kev lag luam thiab kev kho mob. Lub purity ntawm nitrogen tuaj yeem txhim kho los ntawm hydrogen deoxygenation catalysts, thaum lub purity ntawm oxygen tuaj yeem ua tiav los ntawm cov txheej txheem rov ua dua. Txhawm rau txhim kho qhov purity ntawm cov khoom siv roj, cov khoom siv xws li nitrogen purifiers thiab oxygen purifiers feem ntau yog siv, thaum kawg tau txais cov khoom siv oxygen thiab nitrogen siab.

6. Kev siv cov nitrogen thiab oxygen

High-purity nitrogen thiab oxygen ua los ntawm cryogenic cua sib cais tshuab yog dav siv nyob rau hauv ntau yam lag luam. High-purity nitrogen yog siv nyob rau hauv cov tshuaj lom neeg kev lag luam raws li ib tug tiv thaiv roj thiab carrier gas, nyob rau hauv cov zaub mov kev lag luam rau preservation thiab ntim, thiab oxygen yog dav siv nyob rau hauv kev kho mob thiab vuam industries. Hauv kev lag luam metallurgical, cov pa oxygen kuj tseem siv los txhim kho kev sib xyaw ua ke thiab txo cov pa roj carbon emissions. Hauv cov ntawv thov no, qhov purity ntawm cov pa roj yog tus yuam sij rau kev txiav txim siab nws qhov kev siv tau, thiab kev siv tshuab cryogenic cua sib cais tau txais kev lees paub dav rau nws qhov kev sib cais zoo thiab cov txiaj ntsig siab.

7. Qhov zoo thiab cov kev sib tw ntawm cov tshuab cua cryogenic

Cryogenic cua sib cais tshuab yog nyiam nyob rau hauv kev lag luam sector vim nws siab purity thiab high efficiency. Txawm li cas los xij, cov thev naus laus zis no tseem ntsib qee qhov kev sib tw, xws li kev siv hluav taws xob siab thiab cov nqi kho khoom siab. Txhawm rau txo kev siv hluav taws xob, cov cuab yeej siv hluav taws xob sib cais niaj hnub no feem ntau tuaj nrog cov txheej txheem txuag hluav taws xob, xws li cov khoom siv hluav taws xob rov qab thiab ntau theem compression txias tshuab. Tsis tas li ntawd, daim ntawv thov ntawm automation tswj thev naus laus zis tau txhim kho kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov cua sib sib zog nqus cryogenic cua sib cais. Los ntawm kev txhim kho thev naus laus zis thiab kev txhim kho cov cuab yeej siv, lub zog ua haujlwm thiab kev ruaj ntseg ntawm kev sib sib zog nqus cryogenic cua sib cais tshuab tau raug txhim kho tsis tu ncua, ntxiv kev txhawb nqa lawv daim ntawv thov hauv ntau qhov kev lag luam.

Sib sib zog nqus cryogenic huab cua sib cais tam sim no yog ib txoj hauv kev zoo tshaj plaws los tsim cov nitrogen thiab oxygen. Nws zoo cais thiab ntxuav cov pa oxygen thiab nitrogen los ntawm huab cua los ntawm ntau cov kauj ruam xws li kev kho cua ua ntej, compression, txias, liquefaction, thiab distillation. Txawm hais tias cov txheej txheem sib sib zog nqus cryogenic huab cua sib cais muaj lub zog siv zog thiab cov cuab yeej nyuaj, nws cov txiaj ntsig sib cais tau zoo thiab cov khoom lag luam siab purity ua rau cov cuab yeej no tseem ceeb hauv ntau qhov kev lag luam.
