300NM3 /, 99.99 purity nitrogen generator

Nitrogen, raws li cov pa ntau tshaj plaws nyob rau hauv huab cua, yog inexhaustible thiab inexhaustible. Nws yog xim tsis muaj ntxhiab, tsis muaj ntxhiab, pob tshab, subinert thiab tsis txhawb lub neej. High purity nitrogen feem ntau yog siv los tiv thaiv cov pa hauv qhov chaw uas cov pa oxygen lossis cua cais tawm. Cov ntsiab lus ntawm nitrogen (N2) nyob rau hauv huab cua yog 78.084% (lub ntim ntawm ntau yam gases nyob rau hauv cov huab cua muab faib ua N2: 78.084%, O2: 20.9476%, Argon: 0.9364%, CO2: Lwm yam H2, CH4, N2O, O3, SO2, NO2, thiab lwm yam, tab sis cov ntsiab lus me me), molecular hnyav yog 28, boiling point: -195.8, condensation point: -210.

Siab viav vias adsorption (PSA) nitrogen ntau lawm txheej txheem yog siab adsorption, atmospheric desorption, yuav tsum siv compressed cua. Qhov zoo tshaj plaws adsorption siab ntawm carbon molecular sieve siv tam sim no yog 0.75 ~ 0.9MPa. Cov pa roj hauv tag nrho cov nitrogen ntau lawm yog nyob rau hauv siab thiab muaj kev cuam tshuam lub zog. Ob, PSA nitrogen ntau lawm txoj cai: JY / CMS siab hloov adsorption nitrogen tshuab yog carbon molecular sieve raws li adsorbent, siv siab adsorption, kauj ruam-down desorption txoj cai los ntawm huab cua adsorption thiab tso tawm oxygen, thiaj li mus cais cov khoom siv tsis siv neeg nitrogen. Cov pa roj carbon molecular sieve yog ib yam ntawm cov thee ua cov khoom siv tseem ceeb, tom qab sib tsoo, oxidation, molding, carbonization thiab ua tiav los ntawm cov txheej txheem tshwj xeeb zawv zawg, nto thiab sab hauv cylindrical granular adsorbent uas yog tag nrho ntawm qhov pores, hauv cov xim dub, cov groove faib li. qhia hauv daim duab hauv qab no: carbon molecular sieve pore loj faib cov yam ntxwv ntawm O2, N2, yog li nws tuaj yeem paub qhov sib cais dynamic. Qhov pore qhov loj me no tso cai rau cov pa sib txawv kom sib txawv rau hauv qhov pores ntawm molecular sieve ntawm tus nqi sib txawv yam tsis muaj kev tawm tsam ib qho ntawm cov pa roj hauv qhov sib tov (cua). Cov nyhuv ntawm cov pa roj carbon molecular sieve ntawm kev sib cais ntawm O2 thiab N2 yog raws li qhov sib txawv me me ntawm lub kinetic txoj kab uas hla ntawm ob gases. O2 muaj qhov me me kinetic txoj kab uas hla, yog li nws muaj qhov nrawm nrawm dua nyob rau hauv micropores ntawm carbon molecular sieve, thaum N2 muaj qhov loj kinetic txoj kab uas hla, yog li tus nqi diffusion qeeb dua. Lub diffusion ntawm dej thiab CO2 hauv huab cua compressed zoo ib yam li cov pa oxygen, thaum argon diffuses maj mam. Qhov kawg concentration ntawm adsorption kem yog sib tov ntawm N2 thiab Ar. Cov yam ntxwv adsorption ntawm carbon molecular sieve rau O2 thiab N2 yuav intuitively qhia los ntawm equilibrium adsorption nkhaus thiab dynamic adsorption nkhaus: los ntawm ob lub adsorption curves, nws yuav pom tau hais tias qhov nce ntawm adsorption siab tuaj yeem ua rau lub peev xwm adsorption ntawm O2 thiab N2 nce. tib lub sijhawm, thiab qhov nce ntawm O2 adsorption muaj peev xwm loj dua. Lub siab viav vias adsorption lub sij hawm luv luv, thiab lub peev xwm adsorption ntawm O2 thiab N2 nyob deb ntawm kev sib npaug (qhov siab tshaj plaws), yog li qhov sib txawv ntawm qhov sib txawv ntawm O2 thiab N2 ua rau lub peev xwm adsorption ntawm O2 zoo heev tshaj li ntawm N2 nyob rau hauv luv luv. lub sijhawm. Siab viav vias adsorption nitrogen ntau lawm yog siv cov pa roj carbon molecular sieve xaiv adsorption yam ntxwv, siv lub siab adsorption, decompression desorption voj voog, kom compressed cua hloov mus rau hauv lub adsorption ntauwd (tseem tuaj yeem ua tiav los ntawm ib tus pej thuam) kom ua tiav huab cua sib cais, thiaj li mus txuas ntxiv tsim cov khoom purity siab nitrogen.
