Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab hluav taws xob nitrogen (siv tam sim no siv lub zog viav vias adsorption ua piv txwv): Lub tshuab hluav taws xob nitrogen siv cov cua compressed raws li cov khoom siv raw thiab carbon molecular sieve ua tus adsorbent. Nyob rau hauv ib lub siab, lub adsorption ntawm oxygen nyob rau hauv cov huab cua los ntawm carbon molecular sieve yog ntau dua li ntawm nitrogen. Yog li ntawd, feem ntau ntawm cov pa oxygen nyob rau hauv cov huab cua yuav adsorbed, thaum nitrogen yuav raug tso tseg thiab nkag mus rau hauv lub system los ntawm lub tso pa pipeline. Raws li cov yam ntxwv sib txawv ntawm cov pa roj carbon molecular sieves nyob rau hauv cov nqe lus ntawm adsorption muaj peev xwm ntawm adsorbed gases nyob rau hauv txawv pressures, lub adsorption ntawm oxygen ntawm molecular sieves yuav txo nyob rau hauv tsis tshua muaj siab. Los ntawm kev txo qhov siab hauv lub adsorber, qhov adsorption ntawm oxygen ntawm molecular sieves yog txo, tso tawm cov pa adsorbed, uas yog cov txheej txheem rov tsim dua ntawm molecular sieves. Los ntawm kev siv cov programmable tswj ntawm qhov qhib thiab kaw ntawm pneumatic li qub, kev hloov pauv ntawm cov yees A thiab B tuaj yeem ua tiav, nrog rau kev sib zog nqus adsorption thiab decompression regeneration kom tiav oxygen nitrogen cais thiab tau txais nitrogen tsim nyog. Nws yuav tsum tau muab sau tseg tias carbon molecular sieves ib txhij adsorb oxygen thiab nitrogen nyob rau hauv cov huab cua, thiab lawv adsorption muaj peev xwm kuj nce nrog nce siab. Tsis tas li ntawd, tsis muaj qhov sib txawv tseem ceeb hauv qhov sib npaug adsorption muaj peev xwm ntawm oxygen thiab nitrogen ntawm tib lub siab. Yog li ntawd, nws yog ib qho nyuaj rau ua tiav kev sib cais ntawm oxygen thiab nitrogen nkaus xwb raws li kev hloov siab. Yog hais tias ntxiv kev txiav txim siab yog muab rau adsorption ceev, cov yam ntxwv adsorption ntawm oxygen thiab nitrogen tuaj yeem paub qhov txawv. Txoj kab uas hla ntawm oxygen molecules yog me dua li ntawm nitrogen molecules, Yog li ntawd, tus nqi diffusion yog ntau pua lub sij hawm sai dua nitrogen, yog li cov adsorption tus nqi ntawm oxygen ntawm carbon molecular sieves kuj ceev heev, ncav cuag tshaj 90% nyob rau hauv ib feeb; Nyob rau lub sijhawm no, tus nqi adsorption ntawm nitrogen tsuas yog kwv yees li 5%, yog li ntawm lub sijhawm no, feem ntau ntawm cov pa oxygen adsorbed yog oxygen, thaum cov nitrogen ntxiv feem ntau yog nitrogen. Nyob rau hauv txoj kev no, yog tias lub sij hawm adsorption tswj tsis pub dhau 1 feeb, oxygen thiab nitrogen tuaj yeem raug cais ua ntej. Hauv lwm lo lus, adsorption thiab desorption yog ua tiav los ntawm qhov sib txawv ntawm qhov sib txawv, nrog adsorption tshwm sim thaum lub siab nce thiab desorption tshwm sim thaum lub siab txo. Qhov sib txawv ntawm cov pa thiab nitrogen yog tiav los ntawm kev tswj lub sij hawm adsorption, uas yog luv heev. Oxygen tau tag nrho adsorbed, thaum nitrogen tseem tsis tau muaj sij hawm rau adsorb, thiab cov txheej txheem adsorption nres. Yog li ntawd, lub siab viav vias adsorption nitrogen ntau lawm yuav tsum tau hloov lub siab thiab lub sij hawm yuav tsum tau tswj nyob rau hauv 1 feeb 4, Nkag siab rau lwm yam nitrogen generators 1. Sib sib zog nqus cua txias cua cais nitrogen generators: sib sib zog nqus txias nitrogen generators tsis tau tsuas yog tsim nitrogen tab sis kuj ua kua. nitrogen, ua tau raws li cov txheej txheem yuav tsum tau ua rau kua nitrogen. Lawv tuaj yeem khaws cia rau hauv cov kua nitrogen cia tank. Thaum muaj kev sib cuam tshuam ntawm nitrogen lossis kev kho me me rau cov khoom sib cais cua, cov kua nitrogen hauv lub tank cia nkag mus rau lub vaporizer thiab ua kom sov ua ntej xa mus rau cov khoom nitrogen pipeline kom tau raws li qhov xav tau nitrogen ntawm cov txheej txheem. Sib sib zog nqus cua txias sib cais rau nitrogen ntau lawm siv cua raws li raw khoom, uas yog compressed, purified, thiab ces liquefied rau hauv cov kua cua los ntawm tshav kub exchanger. Cov huab cua ua kua feem ntau yog sib xyaw ua kua oxygen thiab kua nitrogen. Los ntawm kev siv cov ntsiab lus kub sib txawv ntawm cov kua oxygen thiab kua nitrogen (ntawm 1 atmospheric siab, qhov qub muaj qhov kub ntawm -183 degree, thaum tom kawg muaj qhov kub ntawm -196 degree), nitrogen yog tau los ntawm kev cais lawv los ntawm distillation hauv cov kua cua. Cov cuab yeej siv cua txias cua sib cais nitrogen yog qhov nyuaj, npog thaj tsam loj, muaj cov nqi tsim kho siab, muaj kev nqis peev loj ib zaug, cov nqi khiav lag luam siab, qis roj ntau lawm (12-24 teev), siab installation yuav tsum, thiab ib lub voj voog ntev. Lub tshuab cua cryogenic sib cais nitrogen tsim khoom yog tsim rau cov chaw uas muaj cov khoom siv nitrogen loj thiab cov kua nitrogen uas yuav tsum tau ua, thaum nruab nrab thiab me me nitrogen ntau lawm zoo li kev lag luam.
