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 lub ntsiab lus sib txawv ntawm cov pa oxygen 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 tsis kub distillation ". Txoj kev no tuaj yeem tsim cov kua nitrogen thiab kua oxygen tsawg, cov khoom loj loj; qhov tsis zoo yog peev loj, feem ntau siv nitrogen thiab oxygen thov 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, qhov 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 kim thiab qhov nkag mus tau qis, yog li nws yog siv rau tshwj xeeb lub hom phiaj me me, xws li mobile nitrogen ua tshuab.
Molecular sieve siab adsorption method (PSA) yog huab cua raws li raw khoom, carbon molecular sieve li adsorbent, siv lub siab adsorption txoj cai, siv cov pa roj 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, high degree ntawm automation, tsis tshua muaj zog purity siv tshuab ua ntej siv nitrogen siab. tib neeg adsorption ntauwd, cov dej hauv cov huab cua yuav tsum tau qhuav kom txo cov dej yaig ntawm cov dej molecular sieve thiab txuas ntxiv lub neej kev pab cuam ntawm lub molecular sieve nyob rau hauv cov pa 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 kom qhuav rov qab.
