Raws li cov khoom siv tseem ceeb hauv kev lag luam niaj hnub no, cov tshuab hluav taws xob nitrogen tau siv dav hauv kev ntim khoom noj, kev ua hlau, kev tsim hluav taws xob thiab lwm yam haujlwm. Nws lub luag haujlwm tseem ceeb yog cais siab -purity nitrogen los ntawm huab cua los ntawm cov txheej txheem ntawm lub cev. Kab lus no yuav piav qhia cov ntsiab lus tseem ceeb ntawm cov tshuab hluav taws xob nitrogen hauv cov khoom siv nitrogen rau koj thiab txheeb xyuas lawv ua ke nrog cov ntaub ntawv tshwj xeeb.
1. Cua pretreatment: tso lub hauv paus
Cov txheej txheem tsim cov nitrogen ua ntej yuav tsum tau cov cua compressed tuaj kom huv thiab qhuav. Qhov no yog vim huab cua muaj cov dej noo, roj thiab lwm yam impurities, uas ncaj qha cuam tshuam cov nyhuv ntawm cov kauj ruam tom ntej thiab qhov kawg purity ntawm nitrogen. Raws li kev lag luam cov qauv, qhov zoo ntawm compressed cua nkag mus rau hauv lub nitrogen ntau lawm system yuav tsum mus txog rau chav kawm ntawv 4 los yog siab dua nyob rau hauv ISO 8573-1: 2010, uas yog, cov dej ntsiab lus tsis pub tshaj 3g / m³ thiab cov roj cov ntsiab lus tsis tshaj 1mg / m³. Cov theem no feem ntau suav nrog kev siv cov khoom siv xws li cov cua txias, cov lim dej thiab cov tshuab ziab khaub ncaws.
2. Nitrogen-Kev cais cov pa oxygen: core technology
Tom ntej no yog qhov txuas tseem ceeb ntawm lub tshuab hluav taws xob nitrogen - nitrogen thiab oxygen sib cais. Tam sim no, ob lub thev naus laus zis tseem ceeb tau siv hauv kev ua lag luam kom ua tiav lub hom phiaj no: siab- hloov pauv adsorption (PSA) thiab kev sib cais ntawm daim nyias nyias. Ntawm lawv, PSA thev naus laus zis siv qhov kev xaiv adsorption muaj peev xwm ntawm cov ntaub ntawv carbon molecular sieve cais cov pa roj hauv qhov sib txawv. Ib qho PSA nitrogen ntau lawm system tuaj yeem ua tiav nitrogen purity txog 99.999% thaum lub zog siv qis, nrog hluav taws xob siv li ntawm 0.6 txog 1.2 kWh ib cubic meter ntawm nitrogen. Nyob rau hauv sib piv, membrane sib cais tshuab cia siab rau tshwj xeeb tsim semipermeable daim nyias nyias, tso cai rau nitrogen kom dhau los ntawm daim nyias nyias txheej sai dua, yog li ua tiav kev sib cais ntawm oxygen. Txawm hais tias kev ua haujlwm ntawm kev sib cais tshuab yog yooj yim dua, nws cov nitrogen purity feem ntau tsuas yog ncav cuag li ntawm 95% thiab 99%.
3. Nitrogen rov qab thiab khaws cia: Txhim kho kev ua haujlwm
Txhawm rau txo qis kev siv hluav taws xob thiab txhim kho kev tsim khoom, ntau lub tshuab hluav taws xob siab siab nitrogen tau nruab nrog cov txheej txheem nitrogen rov qab. Lub kaw lus muaj peev xwm ntes tau cov nitrogen uas tsis tau siv thiab rov qhia nws rau hauv cov txheej txheem tsim khoom. Nws tau kwv yees tias cov chaw tsim khoom siv nitrogen rov ua haujlwm tuaj yeem txuag tau tsawg kawg 10% ntawm tag nrho cov kev siv hluav taws xob. Tsis tas li ntawd, nws yog ib qho tseem ceeb sib npaug rau cov tuam txhab uas xav tau cov khoom ruaj khov ntawm siab - zoo nitrogen. Feem ntau hais lus, nws raug nquahu kom teeb tsa lub tso tsheb hlau luam nrog lub peev xwm ntawm 10% -20% ib hnub los tiv thaiv qhov kev xav tau hloov pauv lossis kev xav tau roj txuas ntxiv thaum lub sijhawm tu khoom.
4. Kev soj ntsuam zoo thiab kev ua kom zoo: kev txhim kho tsis tu ncua
Thaum lub sij hawm tag nrho lub voj voog nitrogen, nws yog ib qho tseem ceeb los saib xyuas ntau yam tsis nyob hauv lub sij hawm xws li kub, av noo, siab thiab nitrogen purity. Nrog rau niaj hnub sensing technology thiab automated tswj systems, cov neeg ua hauj lwm yuav kho cov txheej txheem tsis ntau yog kom paub tseeb tias cov khoom ua tau raws li cov kev xav tau zoo qauv. Piv txwv li, qee qhov siab -kawg nitrogen- ua cov cuab yeej siv tau siv lub peev xwm daws teeb meem uas tuaj yeem teeb tsa lub tswb tam sim thiab muab cov kev daws teeb meem thaum muaj xwm txheej txawv txav. Qhov no tsis tsuas yog pab txo cov nqi khiav lag luam, tab sis kuj tseem txhim kho kev ntseeg siab thiab kev nyab xeeb.
Nitrogen generators muaj cov kev cai nruj thiab kev txiav txim siab hauv txhua qhov txuas hauv lub voj voog nitrogen. Txawm hais tias nws tau ua kom ntseeg tau qhov zoo ntawm cov khoom siv hauv huab cua pretreatment theem, kev xaiv tau zoo thaum lub sij hawm nitrogen thiab oxygen cais cov txheej txheem, los yog txawm tias tom qab nitrogen rov qab, kev cia thiab kev soj ntsuam zoo, txhua qhov kev nthuav dav yog ncaj qha ntsig txog cov txiaj ntsig zoo thiab kev lag luam ntawm cov khoom kawg. Yog li ntawd, hauv kev siv tswv yim, cov tuam txhab lag luam yuav tsum nkag siab thiab paub cov ntsiab lus tseem ceeb no kom siv tag nrho cov peev txheej ntawm nitrogen generators thiab ua tau raws li kev lag luam loj hlob. Nyob rau tib lub sijhawm, nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev siv cov khoom siv tshiab, nitrogen ntau lawm technology yuav txuas ntxiv rau kev tsim kho tshiab rau yav tom ntej, coj ntau qhov muaj peev xwm thiab kev loj hlob rau cov lag luam.
