High purity nitrogen cov nroj tsuag tau dhau los ua qhov tseem ceeb hauv ntau qhov kev lag luam xws li tshuaj lom neeg, hluav taws xob, thiab kev siv kho mob. Nitrogen yog ib feem tseem ceeb ntawm yuav luag tag nrho cov kev lag luam no, thiab nws cov purity thiab zoo ua lub luag haujlwm tseem ceeb hauv kev ua kom cov khoom zoo kawg nkaus. Yog li ntawd, kev tsim cov khoom zoo nitrogen yog qhov tseem ceeb tshaj plaws.
Siab viav vias adsorption (PSA) yog ib lub tshuab uas siv tau los ntxuav cov nitrogen los ntawm kev tshem cov pa thiab lwm yam impurities. PSA yog ua raws li lub hauv paus ntsiab lus ntawm cov pa adsorption ntawm cov khoom siv adsorbent. Lub adsorbent yog xaiv tau xaiv raws li nws lub peev xwm los adsorb cov roj molecules ntawm kev txaus siab, thaum tso cai rau lwm cov pa tawm mus.
Hauv cov nroj tsuag siab purity nitrogen, PSA thev naus laus zis tuaj yeem siv los tsim cov nitrogen lossis oxygen los ntawm kev tswj cov adsorption thiab desorption ntawm cov roj molecules. Cov txheej txheem cuam tshuam nrog compressing huab cua mus rau qhov tshwj xeeb siab thiab dhau los ntawm lub txaj ntawm cov khoom adsorbent. Cov khoom siv adsorbent yuav adsorb cov pa oxygen thiab lwm yam impurities, thaum nitrogen dhau los ntawm lub txaj thiab sau rau hauv lub tank cia.
Cov khoom siv adsorbent tuaj yeem rov tsim dua los ntawm kev tso tawm lub siab, uas ua rau cov roj molecules desorb los ntawm cov khoom. Tom qab ntawd cov roj desorbed tau dhau los ntawm lub cev, thiab cov adsorbent yog npaj los adsorb lwm lub voj voog ntawm cov roj molecules.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv PSA thev naus laus zis hauv cov nroj tsuag siab purity nitrogen yog nws cov txiaj ntsig zoo. PSA thev naus laus zis muaj txiaj ntsig zoo thiab tsis xav tau cov cuab yeej siv yooj yim lossis cov neeg ua haujlwm tshwj xeeb los ua haujlwm. Tsis tas li ntawd, nws muaj cov nqi khiav lag luam qis, vim nws tsis tas yuav muaj lub zog sab nraud uas tsis yog compressed cua.
Lwm qhov zoo dua yog nws versatility. PSA thev naus laus zis tuaj yeem tsim cov nitrogen thiab oxygen, nyob ntawm seb cov khoom siv adsorbent xaiv. Oxygen-enriched cua tuaj yeem siv rau hauv ntau qhov kev lag luam xws li kev siv kho mob thiab vuam, uas yuav tsum muaj cov pa oxygen siab.
Txawm li cas los xij, ua kom muaj purity nitrogen los yog oxygen los ntawm PSA thev naus laus zis yuav tsum tau ceev faj xaiv cov khoom siv adsorbent. Cov khoom siv adsorbent yuav tsum muaj kev xaiv siab rau cov roj molecules ntawm kev txaus siab thiab yuav tsum tsim nyog rau kev ua haujlwm ntawm cov nroj tsuag siab purity nitrogen. Tsis tas li ntawd, qhov loj thiab cov duab ntawm cov khoom siv adsorbent yuav tsum tau ua kom zoo kom txo qis kev poob siab thiab xyuas kom zoo adsorption.
Hauv kev xaus, PSA thev naus laus zis yog ib txoj hauv kev ua tau zoo thiab muaj txiaj ntsig ntawm kev tsim cov purity nitrogen los yog oxygen hauv cov nroj tsuag siab purity nitrogen. Nws muaj ntau yam zoo, nrog rau kev siv ntau yam thiab cov nqi khiav haujlwm tsawg. Txawm li cas los xij, ceev faj xaiv cov khoom siv adsorbent yog qhov tseem ceeb los xyuas kom meej qhov xav tau purity thiab zoo ntawm nitrogen los yog oxygen tsim. Nrog nws cov txiaj ntsig ntau, PSA thev naus laus zis yog qhov kev xaiv zoo rau kev lag luam uas xav tau cov khoom zoo, txhim khu kev qha nitrogen.
