Nitrogen Generating Device

Nitrogen generating ntaus ntawv

Txoj kev no siv cov huab cua ua raw khoom, siv carbon molecular sieve raws li adsorbent, siv lub hauv paus ntsiab lus ntawm siab viav vias adsorption, thiab siv cov kev xaiv adsorption ntawm oxygen thiab nitrogen los ntawm carbon molecular sieve cais nitrogen thiab oxygen. Nws feem ntau hu ua PSA nitrogen ntau lawm. Txoj kev no yog ib qho tshiab nitrogen ntau lawm technology uas tsim sai heev nyob rau hauv lub xyoo 1970s.

Muaj peb hom kev lag luam, xws li kev sib cais huab cua cryogenic, molecular sieve cua cais (PSA) thiab membrane cua sib cais.
Cryogenic cua cais nitrogen ntau lawm
Cryogenic huab cua sib cais nitrogen ntau lawm yog ib txwm siv nitrogen ntau lawm txoj kev nrog keeb kwm ntawm ntau xyoo lawm. Nws siv cov huab cua ua raw khoom, compresses thiab purifies nws, thiab tom qab ntawd siv cov cua kub pauv los liquefy huab cua ua kua. Cov huab cua ua kua feem ntau yog sib xyaw ua kua oxygen thiab kua nitrogen. Ua kom zoo dua ntawm qhov sib txawv ntawm cov ntsiab lus kub ntawm cov kua oxygen thiab kua nitrogen (ntawm 1 cua, qhov kub ntawm qhov qub yog -183 degree thiab tom kawg yog -196 degree), los ntawm kev kho cov cua ua kua, ua rau lawv sib cais kom tau nitrogen. Cryogenic huab cua sib cais cov khoom siv nitrogen yog qhov nyuaj, npog thaj tsam loj, muaj cov nqi tsim vaj tsev siab, kev nqis peev ib zaug hauv cov khoom siv, cov nqi khiav lag luam siab, qis roj ntau lawm (12 mus rau 24 teev), kev tsim kho siab, thiab lub voj voog ntev. Siv rau hauv cov khoom siv, kev teeb tsa thiab kev tsim vaj tsev, cov peev txheej ntawm PSA cov cuab yeej siv nrog tib cov kev qhia tshwj xeeb rau cov khoom siv qis dua 3500Nm3 / h yog 20% ​​mus rau 50% qis dua li cov khoom siv cua sib cais. Cryogenic cua sib cais cov khoom siv nitrogen yog tsim rau cov khoom loj hauv kev lag luam nitrogen ntau lawm, tab sis nruab nrab thiab me me nitrogen ntau lawm yog uneconomical.
Molecular sieve cua cais nitrogen ntau lawm
Piv nrog rau cov txheej txheem nitrogen ntau lawm, nws muaj qhov zoo ntawm cov txheej txheem yooj yim ntws, qib siab ntawm automation, ceev roj ntau lawm (15 mus rau 30 feeb), qis zog noj, khoom purity tuaj yeem hloov kho ntau yam raws li cov neeg siv xav tau, yooj yim khiav lag luam thiab tu, thiab ua haujlwm ceev. Nws muaj cov yam ntxwv ntawm tus nqi qis thiab muaj zog adaptability, yog li nws yog qhov sib tw ntawm cov khoom siv nitrogen hauv qab 1000Nm3 / h. Nws zoo siab txais tos los ntawm cov neeg siv nruab nrab thiab me me nitrogen. PSA nitrogen ntau lawm tau dhau los ua thawj qhov kev xaiv ntawm nruab nrab thiab me me nitrogen cov neeg siv. txoj kev.
Membrane cua sib cais nitrogen ntau lawm
Siv cov huab cua ua raw khoom, nyob rau hauv tej yam kev mob siab, gases nrog txawv zog xws li oxygen thiab nitrogen muaj ntau permeability tus nqi nyob rau hauv daim nyias nyias kom cais oxygen thiab nitrogen. Piv nrog rau lwm cov khoom siv nitrogen-tsim, nws muaj qhov zoo ntawm cov qauv yooj yim, ntim me me, tsis muaj qhov hloov pauv, kev saib xyuas tsawg dua, kev tsim roj sai dua (tsawg dua lossis sib npaug li 3 feeb), thiab yooj yim nthuav dav. Nws yog tshwj xeeb tshaj yog haum rau nitrogen purity Tsawg dua los yog sib npaug rau 98% ntawm cov neeg siv nruab nrab thiab me me nitrogen muaj qhov zoo tshaj plaws ua haujlwm-tus nqi piv. Thaum cov nitrogen purity siab dua 98%, nws tus nqi yog ntau tshaj 15% siab dua li ntawm PSA nitrogen ua cov cuab yeej ntawm tib lub ntsiab lus.
