Cov lus qhia thiab kev ceev faj rau Molecular Sieve Hloov PSA Nitrogen Generator

Thaum ib los sis ntau qhov teeb meem hauv qab no tshwm sim hauv lubPSA nitrogen tiam system, carbon molecular sieve yuav tsum tau hloov:

• Lub purity thiab ntws tus nqi ntawm cov khoom nitrogen ob qho tib si txo qis thiab tsis tuaj yeem tswj tau ntawm qhov teeb tsa.
• Muaj qhov txawv txav hauv kev hloov pauv siab.
• Lub dew point kub nce.
• Lub sijhawm adsorption ntawm lub adsorption ntauwd yuav luv dua.
• Lub molecular sieve yog ib nrab darkened mus rau tsaus xim av los yog stained nrog roj.
• Cov molecular sieve hais yog obviously tawg los yog hmoov.
• Cov khoom siv tau ua haujlwm rau ntau tshaj 10 xyoo.

Npaj ua hauj lwm ua ntej hloov

Kaw thiab Kev Ruaj Ntseg

Nres cov khoom cua compressed, tos kom txog thaum lub siab ntsuas ntawm lub tshuab hluav taws xob nitrogen tag nrho poob rau xoom, ces txiav tawm lub zog hluav taws xob; ua haujlwm tom qab cov cuab yeej txias mus rau chav sov.

Ib puag ncig thiab kev npaj cuab yeej

Ua ntej pib lub molecular sieve filling ua haujlwm, siv cov kev tiv thaiv kev nyab xeeb, xws li cov kaus mom hlau, lub qhov ncauj qhov ntswg, thiab lwm yam.

Npaj cov cuab yeej tshwj xeeb rau molecular sieve funnels thiab molecular sieve filling chim hau.

Yuav tsum tsis muaj sundries muab tso rau hauv av nyob rau hauv lub molecular sieve filling cheeb tsam.

Xaiv qhov qhuav thiab plua plav- ib puag ncig sab hauv tsev dawb rau kev ua haujlwm. Tsis txhob kis tus kab mob tshiab molecular sieve.

Paub meej tias Matching Degree ntawm Molecular Sieve

Cov pa roj carbon molecular sieves nrog tib qhov tshwj xeeb raws li cov khoom qub (xws li qhov loj me, qauv, thiab lwm yam) yuav tsum tau siv, thiab lawv tsis tuaj yeem hloov lossis sib xyaw ntawm qhov xav tau.

Tshem tawm Cov Qub Molecular Sieve

Dismantle Adsorption Ntauwd

Tshem cov bolts thiab txuas cov kav dej raws li cov lus qhia, thiab ua tib zoo tiv thaiv lub sealing nto los ntawm kev puas tsuaj.

Ntxuav cov hmoov seem nyob rau hauv lub pej thuam kom tsis txhob muaj plua plav tawm thiab ua rau tsis zoo tom qab txhaws.

Tshawb xyuas Cov Qauv Sab Hauv

Saib xyuas seb puas muaj xeb lossis puas rau ntawm phab ntsa sab hauv ntawm lub adsorption ntauwd, thiab xyuas seb cov hlau mesh thiab xibtes pad hauv cov khoom ntim puas puas. Kho lossis hloov raws li qhov tsim nyog.

Sau nrog Tshiab Molecular Sieve

Cov av noo rau molecular sieve filling yuav tsum yog <60%, thiab kev tsim kho tuaj yeem ua tiav tom qab kev pom zoo.

Qhib molecular sieves yuav tsum tau siv tam sim ntawd tom qab qhib, thiab lub sij hawm rau sau ib chim ntawm lub tshuab hluav taws xob oxygen yuav tsum tsis pub dhau 8 feeb.

Thaum lub sij hawm molecular sieve filling txheej txheem, siv> 95% inert gas rau purging tiv thaiv nyob rau hauv lub adsorption tank.

Tom qab cov khoom siv oxygen generator tau ntim rau hauv ib zaug, co nws ntawm lub platform kev co lossis los ntawm khob lub tank nrog rauj kom txog thaum lub sieve molecular tsis tso dej.

Nws yog nruj me ntsis txwv tsis pub sib tov sundries thaum sau.

Tom qab sau, ntsuas qhov kev ncua deb ntawm lub dav hlau molecular sieve thiab flange circumferential weld.

Qhov kev ua yuam kev ntawm qhov tseeb sau nyiaj thiab tus nqi sau npe yuav tsum tsis pub tshaj ± 5%, thiab qhov ua yuam kev ntawm kev sau cov nyiaj ntawm ob lub adsorption yees yuav tsum tsis pub tshaj ± 2%.

Tom qab lub molecular sieve filling ua tiav, nws yuav tsum tsis txhob tshaj lub taub hau kab. Yog tias muaj teeb meem tshwm sim, lawv yuav tsum tau tshaj tawm thiab daws raws sijhawm.

Nruab cov txiv maj phaub lev, sab sauv faib phaj, lub caij nplooj ntoos hlav, thiab sab sauv flange npog nyob rau hauv ib ntus, thiab ceev cov bolts.

Tsawg-Kev sim ua haujlwm siab

Thaum pib thawj zaug, thawj zaug ua qhov kev ntsuas siab tsawg -, maj mam nce mus rau qhov ua haujlwm siab, thiab saib xyuas cov kev hloov pauv ntawm lub ntsuas siab kom paub meej tias qhov kev ua haujlwm ruaj khov ntawm lub kaw lus. Yog tias muaj kev hloov pauv txawv txav, lub tshuab yuav tsum raug tso tseg tam sim ntawd rau kev daws teeb meem.

Cua Tightness Test

Tshawb xyuas seb puas muaj qhov xau hauv qhov txuas flange.

Cov Qauv Ntsuas Kev Ua Haujlwm

Tom qab 24 teev ntawm kev ua haujlwm, xyuas seb cov nitrogen purity thiab ntws npaum li cas raws li cov qauv. Yog tias tus nqi xav tau tsis ncav cuag, yuav tsum tau hloov kho ntxiv thiab tshuaj xyuas.

Pov tseg cov khib nyiab Molecular Sieve

Cov pa roj carbon molecular sieves siv hauv PSA nitrogen tiam, txawm tias tshiab, qub, lossis tsis siv, yuav tsis tso cov khoom tsis zoo nyob rau hauv kev ua haujlwm ib txwm muaj, thiab lawv yuav ua rau muaj kev hem thawj rau kev noj qab haus huv lossis ib puag ncig. Yog li ntawd, qhov tsis raug molecular sieves tuaj yeem muab pov tseg los ntawm lawv tus kheej.

Lawv kuj tseem tuaj yeem muab pov tseg los ntawm cov tuam txhab kev tshaj lij cov khoom pov tseg pov tseg, uas yuav ua haujlwm zoo raws li kev tiv thaiv ib puag ncig hauv zos, cov cai thiab cov cai kom tsis txhob muaj kev cuam tshuam rau ib puag ncig.
