Yog tias koj tau siv sijhawm txaus nyob ib puag ncig cov cuab yeej siv khoom lag luam, koj yuav pom qee yam nthuav. Qee tus neeg xav tias lub tshuab hluav taws xob nitrogen tsuas yog xav tau ua haujlwm, thaum lwm tus tsom mus rau txhua tus lej lej. Hauv daim ntawv, 99 feem pua thiab 99.9 feem pua purity txawv ntawm tsuas yog cuaj. Tab sis qhov sib txawv tiag tiag hauv kev xaiv cov khoom siv, kev siv hluav taws xob, thiab cov nqi tu lub sij hawm ntev yog ntau dua li cov neeg feem coob xav tau. Ntawm Shenger Gas, peb tau ua haujlwm nrog ntau tus neeg siv ntsib qhov kev txiav txim siab no, thiab ntawm no yog qhov kev paub meej ntawm cov nqi tiag tiag.
Purity Definition tsis yog ib qho kev ua si xwb
Ntau tus neeg pom kev txav los ntawm 99 feem pua rau 99.9 feem pua raws li qhov yooj yim 0.9 feem pua nce ntxiv. Tab sis hauv kev siv tiag tiag, kev sib raug zoo tsis yog linear. Nitrogen purity feem ntau txhais tau tias yog qhov hloov pauv ntawm cov pa seem seem . 99 feem pua purity txhais tau hais tias txog 10000 ppm ntawm cov pa los ntawm ntim, thaum 99.9 feem pua purity txhais tau hais tias txog 1000 ppm, thiab 99.99 feem pua hais txog 100 ppm.
Txhua zaus koj ntxiv ib cuaj, qhov seem oxygen concentration poob los ntawm kaum zaug. Kev ua tiav siab dua purity yuam cov txheej txheem roj sib cais hauv lub tshuab hluav taws xob ua haujlwm hnyav dua. Qhov no cuam tshuam ncaj qha rau peb qhov tseem ceeb: tus nqi khoom siv, kev siv hluav taws xob ua haujlwm, thiab tus nqi nitrogen rov qab.
Qhov twg cov cuab yeej nqis peev sib txawv nyob
Rau PSA (siab viav vias adsorption) nitrogen generators, purity yuav tsum txiav txim siab tus nqi thiab hom carbon molecular sieve xav tau. Ntawm 99 feem pua purity, tus qauv carbon molecular sieve ua tau zoo nyob rau hauv qhov tsim nyog airflow. Lub adsorption ntauwd loj thiab valve specifications nyob rau hauv tus nqi zoo.
Tab sis thaum koj tsiv mus rau 99.9 feem pua, txhua yam hloov. Lub micropores ntawm molecular sieve yuav tsum cais cov pa oxygen thiab nitrogen ntau dua. Qhov no txhais tau tias rau tib cov pa tawm, lub sieve ntim yuav tsum tau nce los ntawm 20 mus rau 35 feem pua. Lub adsorption ntauwd yuav tsum loj dua, thiab cov pneumatic li qub, silencers, thiab tswj cov lus teb raug yuav tsum tau txhim kho. Rau lub tshuab hluav taws xob nitrogen ntsuas ntawm 10 Nm³ ib teev twg, 99 feem pua purity system yuav raug nqi ntawm 50000 thiab 70000 RMB, thaum 99.9 feem pua tau dhia mus rau 80000 txog 110000 RMB. Tus nqi sib txawv ntawm 30 mus rau 50 feem pua yog ntau heev.
Rau membrane cais nitrogen generators, qhov xwm txheej zoo sib xws. Cov purity siab dua yuav tsum tau ntev dua membrane modules thiab ib tug ruaj khov compressed cua pretreatment system. Cov kev xaiv ntawm daim nyias nyias kuj hloov los ntawm lub hom phiaj dav dav mus rau qib siab xaiv, thiab cov khoom siv tau txais txiaj ntsig qee zaum txawm tias pom tseeb dua nrog PSA.
Ob qhov tseem ceeb sib txawv hauv cov nqi zog
Qhov sib txawv tseem ceeb ntawm cov nqi khiav haujlwm yog los ntawm ob yam: compressed cua noj thiab nitrogen rov qab tus nqi.
Lub tshuab hluav taws xob nitrogen tsis ncaj qha tig cua rau hauv nitrogen. Nws cais thiab tso cov pa oxygen tawm. Qhov siab dua qhov xav tau purity, qhov tsawg nitrogen koj tuaj yeem khaws cia rau ib chav tsev ntawm lub sijhawm. Ntawm 99 feem pua purity, tus nqi rov qab feem ntau nce mus txog 40 mus rau 50 feem pua, lub ntsiab lus rau txhua 100 qhov chaw ntawm huab cua uas tau kos rau hauv, koj tau txais 40 mus rau 50 feem ntawm cov nitrogen siv tau. Ntawm 99.9 feem pua, tus nqi rov qab poob rau 25 mus rau 35 feem pua.
Kev rov qab qis dua txhais tau hais tias huab cua compressor yuav tsum ua haujlwm tsis muaj txiaj ntsig ntau dua. Rau tib qhov tso zis nitrogen ntawm 10 Nm³ ib teev twg, 99 feem pua purity system xav tau li 20 Nm³ ib feeb ntawm cov pa kom tsawg, thaum 99.9 feem pua qhov system yuav xav tau ntau tshaj 30 Nm³ ib feeb. Lub compressor feem ntau yog cov neeg siv hluav taws xob loj tshaj plaws hauv lub tshuab tsim nitrogen. Ntawm tus nqi hluav taws xob ntawm 0.7 RMB ib kWh, khiav tsis tu ncua rau 8000 teev hauv ib xyoos, tus nqi hluav taws xob txhua xyoo sib txawv ntawm ob txoj kev xaiv purity tuaj yeem nyob nruab nrab ntawm 15000 thiab 25000 RMB.
Ntau tus neeg siv saib dhau ib qho tseem ceeb. Lub tshuab hluav taws xob siab purity nitrogen tsis tas yuav khiav ntawm nws hom purity siab tshaj txhua lub sijhawm. Yog tias koj daim ntawv thov tiag tiag tsuas yog xav tau 99 feem pua purity tab sis lub tshuab tau teeb tsa rau 99.9 feem pua, koj tsis yog tsuas yog siv hluav taws xob xwb tab sis kuj tseem ua kom lub zog degradation ntawm molecular sieve los ntawm ya raws thiab roj. Ntawm qhov tod tes, yog tias koj cov txheej txheem qee zaus xav tau kev purity siab tab sis feem ntau khiav ntawm cov theem nruab nrab, ib qho kev hloov dual purity hloov tau zoo sib npaug tus nqi thiab kev thov.
Ncua Kev Saib Xyuas Qhov txawv
Cov tshuab purity qis dua muaj kev ua siab ntev dua rau kev hloov pauv huab cua zoo. Raws li ntev raws li lub siab dew point tswj ntawm 2 thiab 5 degrees Celsius thiab cov roj cov ntsiab lus nyob qis dua 0.01 mg ib cubic meter, lub molecular sieve tau yooj yim nyob rau 8 mus rau 10 xyoo.
Cov tshuab purity siab dua xav tau kev saib xyuas ntau dua. Carbon molecular sieve yog heev rhiab heev rau roj pos huab thiab dej vapor. Txawm tias cov kab ntawm lubricating roj vapor nkag mus rau hauv lub adsorption ntauwd yuav maj mam thaiv cov micropores thiab ua rau qeeb qeeb hauv purity. Txhawm rau tiv thaiv molecular sieve, koj yuav tsum tau ntxiv cov ntxaij lim dej kom meej thiab qhib cov pa roj carbon ntau rau cov cua compressed. Tus nqi ib zaug rau cov khoom siv ntxiv no yog kwv yees li 10000 txog 20000 RMB, thiab cov ntsiab lus lim yuav tsum tau hloov ntau zaus, ntxiv 2000 txog 3000 RMB ib xyoos rau cov nqi siv tau.
Lub purity analyzer configuration kuj txawv. Rau 99 feem pua purity, koj tuaj yeem siv lub tshuab hluav taws xob hluav taws xob uas raug nqi txog 1000 RMB, thiab calibration ib xyoos ib zaug feem ntau txaus. Rau 99.9 feem pua purity, feem ntau koj xav tau ib tug zirconia los yog paramagnetic analyzer raug nqi 5000 rau 10000 RMB, nrog rau kev nruj me ntsis rau kev teeb tsa txoj hauj lwm thiab cov qauv roj pretreatment, thiab kev siv zog ntau dua.
Daim duab Tus nqi tag nrho ua kom pom tseeb dua
Piv txwv li kev lag luam me me rau nruab nrab kev lag luam siv nitrogen txuas ntxiv 24 teev hauv ib hnub nrog tus nqi ntws ntawm 5 Nm³ ib teev thiab cov khoom siv lub neej ntawm 8 xyoo.
Rau 99 feem pua purity txoj kev npaj: cov cuab yeej peev nyiaj yog 60000 RMB, hluav taws xob txhua xyoo yog 30000 RMB, tus nqi tu txhua xyoo 4000 RMB, thiab tag nrho 8 xyoo raug nqi txog 330000 RMB.
Rau 99.9 feem pua purity txoj kev npaj: cov cuab yeej siv peev yog 90000 RMB, hluav taws xob txhua xyoo raug nqi txog 50000 RMB, tus nqi tu txhua xyoo 7000 RMB, thiab tag nrho 8 xyoo raug nqi txog 550000 RMB.
Qhov sib txawv ntawm ob yog 220000 RMB. Txawm hais tias qhov sib txawv no tsim nyog nws tag nrho nyob ntawm koj txoj kev xav tau. Rau vuam shielding, ntim zaub mov nitrogen, thiab tshuaj blanketing, 99 feem pua purity twb ruaj khov thiab txaus. Rau cov ntawv thov xws li laser txiav kev pab, hluav taws xob tivthaiv reflow soldering, thiab kev hloov tshuaj tsis muaj menyuam, 99.9 feem pua lossis ntau dua purity yog tsim nyog los xyuas kom meej cov txheej txheem tawm los.
Peb Cov Lus Qhia rau Cov Neeg Yuav Khoom
Ua ntej, tsis txhob blindly caum siab purity. Txaus purity yog zoo txaus. Cov npoo ntxiv tsuas yog ua rau cov nqi hluav taws xob ntau dua. Koj tuaj yeem ua ntej kuaj qhov tseeb oxygen kam rau siab tshaj qhov txwv ntawm koj qhov kev siv, thiab tom qab ntawd tawm ntawm qhov kev nyab xeeb ntawm 1 mus rau 2 feem pua cov ntsiab lus.
Thib ob, them sai sai rau qhov dej lwg point specification. Ntau tus neeg siv tsuas yog saib purity thiab tsis quav ntsej cov dej noo hauv cov nitrogen. Rau precision vuam lossis kev tsim khoom siv hluav taws xob, kev puas tsuaj los ntawm cov dej noo yog qee zaum ntau dua li ntawm cov pa oxygen. Yog tias koj cov peev nyiaj tsawg, ua qhov tseem ceeb ua tau raws li qhov xav tau ntawm cov dej lwg, thiab koj tuaj yeem txo qis qhov xav tau purity.
Thib peb, tawm hauv chav rau kev hloov kho tshiab yav tom ntej. Yog tias koj tam sim no xav tau 99 feem pua purity tab sis tuaj yeem ntxiv cov cuab yeej siv siab tshaj peb xyoos tom qab, nws raug nquahu kom khaws 20 mus rau 30 feem pua ntawm qhov chaw ntxiv nyob rau hauv lub ntim ntauwd adsorption thaum xaiv, thiab xaiv cov kev tswj hwm nrog cov txheej txheem programmable. Kev siv nyiaj me ntsis ntawm kev rov ua dua tshiab yog qhov txiaj ntsig zoo dua li hloov tag nrho lub tshuab hluav taws xob tom qab.
