Yuav ua li cas xaiv lub tshuab hluav taws xob nitrogen uas tsim nyog

Ua ntej txiav txim siab txog cov qauv tshwj xeeb (piv txwv li Kev Tsim Khoom Nitrogen ib teev, nitrogen purity, qhov hluav taws xob tawm, dew point), peb yuav tsum tsom mus rau kev sib piv kev ua tau zoo thiab cov yam ntxwv ntawmlub tshuab hluav taws xob nitrogen, thiab ua qhov kev xaiv zoo raws li peb cov xwm txheej ib puag ncig uas twb muaj lawm.

Cov kev cai rau nitrogen hauv ntau yam lag luam

A, Metallurgy thiab kev lag luam ua hlau

Qee cov lag luam no xav tau nitrogen uas muaj qhov huv siab tshaj 99.5%, thaum lwm tus xav tau nitrogen zoo uas muaj qhov huv siab tshaj 99.9995% thiab qhov dew point qis dua -65°C. Qhov no yuav tsum tau txiav txim siab raws li cov xwm txheej ntawm tus neeg siv khoom.

B, Kev lag luam tshuaj lom neeg thiab cov ntaub ntawv tshiab

Feem ntau, qhov yuav tsum tau ua kom nitrogen purity tsis siab, thiab ntau yam purities ntau dua 98% siv tau. Txawm li cas los xij, qhov tseeb xav tau nyob ntawm tus neeg siv khoom tus kheej cov txheej txheem tsim khoom.

C, Kev lag luam zaub mov thiab tshuaj

Feem ntau cov lag luam zaub mov tsis muaj qhov yuav tsum tau nitrogen ntau, thiab 99.5% ~ 99.9% purity tuaj yeem ua tau raws li qhov yuav tsum tau ua. Muaj ob peb lub lag luam zaub mov yuav tsum xaiv 99.99% purity vim yog cov txheej txheem xav tau. Kev lag luam tshuaj feem ntau xav tau nitrogen purity ntawm 99.99% thiab xav kom nws ua los ntawm stainless hlau.

d Kev lag luam hluav taws xob

Feem ntau, qhov yuav tsum tau muaj nitrogen yog qhov siab heev, thiab feem ntau yuav tsum muaj nitrogen purity ntawm 99.99% lossis siab dua.

Kev sib piv ntawm ntau yam Cov Pa roj Generators

A, Cryogenic cua sib cais nitrogen generator

Kev tsim cov nitrogen los ntawm cua cryogenic yog ib txoj kev tsim cov nitrogen ib txwm muaj uas muaj keeb kwm yuav luag ntau xyoo lawm. Nws siv cua ua cov khoom siv raw, nias thiab ntxuav nws, thiab tom qab ntawd siv kev sib pauv cua sov los ua kom cov huab cua ua kua. Cov huab cua ua kua feem ntau yog kev sib xyaw ntawm cov pa oxygen thiab cov pa nitrogen ua kua. Cov ntsiab lus kub sib txawv ntawm cov pa oxygen thiab cov pa nitrogen ua kua (ntawm 1 huab cua, qhov kub ntawm thawj zaug yog -183 ℃ thiab qhov kawg yog -196 ℃) yog siv los cais lawv los ntawm kev sib cais cov huab cua ua kua kom tau txais nitrogen. Cov khoom siv tsim cov nitrogen los ntawm cua cryogenic yog qhov nyuaj, nyob hauv thaj chaw loj, muaj cov nqi tsim kho vaj tse siab, xav tau kev nqis peev ntau dua ib zaug hauv cov khoom siv, muaj cov nqi ua haujlwm siab, kev tsim roj qeeb (12 txog 24 teev), muaj cov kev xav tau kev teeb tsa siab, thiab lub voj voog ntev. Xav txog cov yam ntxwv ntawm cov khoom siv, kev teeb tsa thiab cov khoom siv, qhov ntsuas kev nqis peev ntawm cov khoom siv PSA nrog tib cov lus qhia qis dua 3500Nm3 / h yog 20% ​​txog 50% qis dua li cov khoom siv sib cais cua cryogenic. Cov khoom siv tsim cov nitrogen los ntawm kev sib cais cua cryogenic yog qhov tsim nyog rau kev tsim cov nitrogen hauv kev lag luam loj, thaum kev tsim cov nitrogen nruab nrab thiab me me tsis pheej yig.

B, PSA siab viav adsorption nitrogen generator

Txoj kev siv cua ua cov khoom siv raw, carbon molecular sieve ua adsorbent, siv lub hauv paus ntsiab lus ntawm kev siab nrawm adsorption, thiab siv cov kev xaiv adsorption ntawm oxygen thiab nitrogen los ntawm carbon molecular sieve los cais nitrogen thiab oxygen feem ntau hu ua Kev tsim cov pa nitrogen PSATxoj kev no yog ib txoj kev siv tshuab nitrogen tshiab uas tau tsim sai sai hauv xyoo 1970. Piv nrog rau cov txheej txheem tsim nitrogen ib txwm muaj, nws muaj cov yam ntxwv ntawm cov txheej txheem yooj yim, qib siab ntawm kev ua haujlwm tsis siv neeg, kev tsim roj sai (15-30 feeb), kev siv hluav taws xob tsawg, kev huv ntawm cov khoom tuaj yeem hloov kho hauv ntau yam raws li cov neeg siv xav tau, kev ua haujlwm yooj yim thiab kev txij nkawm, tus nqi ua haujlwm qis, kev hloov kho tau zoo, thiab lwm yam. Yog li ntawd, nws sib tw heev hauv cov khoom siv tsim nitrogen hauv qab 1000Nm3 / h, thiab tau txais tos los ntawm cov neeg siv nitrogen nruab nrab thiab me. Psa Nitrogen kev tsim khoom tau dhau los ua ib txoj hauv kev rau cov neeg siv nitrogen nruab nrab thiab me.

C, Lub tshuab ua pa nitrogen sib cais membrane

Siv cua ua cov khoom siv raw, nyob rau hauv qee qhov xwm txheej siab, oxygen thiab nitrogen raug sib cais los ntawm kev siv cov pa roj sib txawv nrog cov khoom sib txawv xws li oxygen thiab nitrogen hauv daim nyias nyias. Piv nrog rau lwm cov khoom siv tsim nitrogen, nws muaj qhov zoo ntawm cov qauv yooj yim dua, me dua, tsis muaj lub qhov hloov pauv, tsawg dua kev saib xyuas, tsim roj sai dua (≤3 feeb), thiab nthuav dav peev xwm yooj yim. Nws yog qhov tshwj xeeb tshaj yog rau cov neeg siv nitrogen nruab nrab thiab me me nrog nitrogen purity ≤98%, thiab muaj qhov sib piv zoo tshaj plaws ntawm kev ua haujlwm-tus nqi. Thaum nitrogen purity siab dua 98%, nws tus nqi ntau dua 15% dua li ntawm PSA nitrogen generators ntawm tib cov lus qhia.

Cov yam tseem ceeb uas cuam tshuam rau tus nqi ntawm cov tshuab hluav taws xob nitrogen

1. Tus nqi yuav ib zaug xwb rau tag nrho lub tshuab. Tam sim no, muaj ntau hom lag luam hauv khw, thiab qhov zoo yog sib npaug rau tus nqi.

2. Kev ruaj khov ntawm kev ua haujlwm ntawm cov khoom siv thiab lub neej kwv yees.

3. Cov nqi khiav lag luam thiab kev saib xyuas txhua xyoo.

4. Cov nqi dej thiab hluav taws xob txhua hnub.
