Nyob rau hauv kev lag luam teb, nitrogen generator yog dav siv nyob rau hauv petrochemical, natural gas liquefaction, metallurgy, zaub mov, tshuaj thiab electronics kev lag luam. Cov khoom siv nitrogen ntawm nitrogen generator tuaj yeem siv los ua cov cuab yeej siv roj, tab sis kuj yog cov khoom siv raw thiab cov tub yees, uas yog cov khoom siv tseem ceeb rau pej xeem hauv kev tsim khoom. Cov txheej txheem ntawm nitrogen generator feem ntau muab faib ua peb hom: sib sib zog nqus txias cua sib cais txoj kev, membrane cais txoj kev thiab molecular sieve siab hloov adsorption method (PSA).
Txoj kev sib sib zog nqus cua txias sib cais yog siv qhov sib txawv ntawm cov ntsiab lus kub ntawm cov pa thiab nitrogen hauv huab cua, thiab tsim cov kua nitrogen thiab kua oxygen los ntawm lub hauv paus ntsiab lus ntawm compression, tub yees thiab kub distillation ". Txoj kev no tuaj yeem tsim cov kua nitrogen tsawg thiab cov pa oxygen, cov khoom loj loj; qhov tsis zoo yog kev nqis peev loj, feem ntau siv nitrogen thiab oxygen xav tau hauv metallurgy thiab tshuaj lom neeg kev lag luam.
Membrane sib cais txoj kev yog huab cua raws li raw khoom, nyob rau hauv tej yam kev mob siab, siv oxygen thiab nitrogen nyob rau hauv daim nyias nyias nrog txawv permeability tus nqi los ua oxygen thiab nitrogen sib cais? Cov qauv no muaj qhov zoo ntawm cov qauv yooj yim, tsis muaj qhov hloov pauv, ntim me me, thiab lwm yam, tab sis vim tias cov khoom siv membrane feem ntau yog nyob ntawm kev xa khoom, tus nqi tam sim no yog kim thiab tus nqi nkag tau qis, yog li nws tsuas yog siv rau lub hom phiaj tshwj xeeb. me me ntws, xws li mobile nitrogen ua tshuab.
Molecular sieve siab adsorption method (PSA) yog huab cua ua raw khoom, carbon molecular sieve li adsorbent, siv lub siab adsorption txoj cai, siv carbon molecular sieve rau oxygen thiab nitrogen adsorption thiab oxygen thiab nitrogen cais txoj kev ". Txoj kev no muaj cov yam ntxwv ntawm cov txheej txheem yooj yim ntws, qib siab ntawm automation, tsawg zog noj thiab siab nitrogen purity, thiab nws yog cov cuab yeej siv dav tshaj plaws. Ua ntej huab cua nkag mus rau tib neeg adsorption ntauwd, cov dej hauv huab cua yuav tsum tau qhuav kom txo cov dej yaig ntawm cov molecular sieve thiab txuas ntxiv lub neej kev pab cuam ntawm molecular sieve. Nyob rau hauv cov txheej txheem PSA nitrogen ntau lawm, lub tshuab ziab khaub ncaws feem ntau yog siv los tshem tawm cov dej noo hauv huab cua. Thaum lub tshuab ziab khaub ncaws yog saturated nrog dej, lub tshuab ziab khaub ncaws yog tshuab rov qab nrog cov cua qhuav kom paub txog kev rov tsim dua tshiab ntawm cov tshuab ziab khaub ncaws.
