PSA chav tsev rau nitrogen ntau lawm: Daim ntawv thov Scenarios hauv Pipeline Purging & Gas Displacement - Cov Ntsiab Lus thiab Cov Lus Qhia Txog Kev Kho

Dab tsi yog aPSA Nitrogen Generator?

A PSA Nitrogen Generatoryog ib qho ntawm -site siab-purity nitrogen ntau lawm ntaus ntawv raws li covSiab Swing Adsorption (PSA)txoj cai. Nws cov khoom tseem ceeb muaj xws li cua compressor (kom muab cov cua compressed), lub tshuab ziab khaub ncaws (kom tshem tawm cov dej noo los ntawm cov cua compressed), ob lub adsorption yees (nrog raumolecular sieve- cov khoom siv tseem ceeb rau cov pa oxygen- cais cov nitrogen), thiab kev tswj xyuas ntse.

Txoj Cai Ua Haujlwm

CovPSAtxheej txheem cia siab rau lub molecular sieve lub xaiv adsorption muaj peev xwm rau oxygen thiab nitrogen:

Adsorption Phase: Thaum compressed, qhuav huab cua nkag mus rau hauv ib tug adsorption ntauwd, lub molecular sieve adsorbs oxygen (thiab kab impurities) nyob rau hauv siab. Nitrogen (uas yog tsis yooj yim adsorbed) dhau los ntawm tus pej thuam thiab tau sau ua cov khoom siv roj.

Desorption Theem: Thaum cov molecular sieve nyob rau hauv thawj pej thuam yog saturated, lub kaw lus hloov mus rau lub thib ob pej thuam (uas txuas ntxiv nitrogen ntau lawm). Thawj tus pej thuam yog depressurized tso tawm adsorbed oxygen thiab impurities, regenerating molecular sieve rau lub voj voog tom ntej.

Qhov kev hloov pauv adsorption no - cov txheej txheem desorption ua kom muaj kev ruaj khov, ruaj khov ntawm siab -purity nitrogen.

Core Zoo

Piv nrog rau cov khoom ntim hauv lub raj mis inert gases,PSA Nitrogen Generatorskev muab: ntawm- qhov chaw tsim khoom (tshem tawm kev thauj mus los / khaws cia txaus ntshai), kho tau nitrogen purity (feem ntau 95%-99.999%), tsis tshua muaj nqi khiav lag luam mus sij hawm ntev, thiab hloov tau yooj yim rau ntau hom kev lag luam xav tau scenarios.

Hauv kev tsim khoom lag luam, kev huv thiab kev nyab xeeb ntawm cov raj xa dej ncaj qha cuam tshuam rau kev tsim khoom lag luam - thiab cov kav dej purging & roj xa tawm yog qhov tseem ceeb ntawm kev sib txuas.PSA Nitrogen Generators, nrog rau lawv cov peev txheej ruaj khov nitrogen, ua lub luag haujlwm tseem ceeb hauv cov kev sib txuas. Tsab ntawv xov xwm no yuav nthuav dav lawv cov ntawv thov tshwj xeeb los muab cov lus qhia rau cov kws kho mob.

I. Cov kev txwv ntawm txoj kev kho cov kav dej li qub

Ua ntej siv davPSA Nitrogen Generators, kev lag luam feem ntau siv compressed cua, chav, los yog yuav inert gases los kho cov kav dej, tab sis cov txheej txheem no muaj qhov tsis zoo:

Compressed cua muaj impurities, uas yooj yim uapipeline corrosionthiab nce kev nyab xeeb;

Chav ua haujlwm tsis zoo rau lub siab- cov kav dej rhiab thiab yuav tsum tau ua kom qhuav ntxiv;

Kev yuav cov roj av inert muaj cov khoom siv qis, muaj peev xwm cia kev nyab xeeb, thiab tsis ruaj tsis khov roj purity.

II. Daim ntawv thov ntawmPSA Nitrogen Generatorshauv Pipeline Purging

Pipeline purging yuav tsum tshem tawm cov khoom seem sab hauv thiab tsis txhob muaj cov kab mob sib kis. Nitrogen tsim los ntawmPSA Nitrogen Generatorsyog qhuav, impurity -dawb, thiab ruaj khov hauv cov khoom, ua tau raws li cov kev xav tau no. Nws qhov zoo muaj xws li:

Nitrogen muaj qhov qis qis qis qis (txog -40 degree), tsis txhob muaj cov kav dej xeb;

Adjustable purity (99.9% -99.999%), yuav tsum tsis muaj kev ntxuav ntxiv tom qab purging;

Adjustable siab (0.6-1.6MPa), yoog raws cov kav dej ntawm cov khoom sib txawv.

Hauv kev ua haujlwm: Teem lub nitrogen ntws tus nqi (50-200m³ / h) thiab siab raws li cov kav dej; rau cov kav dej ntev, segmented purging yog pom zoo. Purging tiav tuaj yeem txiav txim siab los ntawm cov ntawv lim thiab cov dew point detectors.

III. Daim ntawv thov ntawmPSA Nitrogen Generatorshauv Gas Displacement

Kev hloov pauv roj yog siv los hloov cov xov xwm hauv cov kav dej, tiv thaiv kev nyab xeeb.PSA Nitrogen Generatorsleverage nitrogen lub inertness kom ua tiav kev nyab xeeb hloov chaw. Tej yam xwm txheej muaj xws li:

Kev lag luam tshuaj: Hloov cov huab cua hauv cov kav dej uas muaj cov khoom siv hluav taws xob / hluav taws xob tawg, txo qishydrocarbon concentrationqis dua 1%;

Kev lag luam zaub mov: Hloov cov huab cua hauv cov kav dej kom ncua kev tshaj tawm tsis zoo thiab tiv thaivmicrobial kev loj hlob;

Kev lag luam hluav taws xob: Siv nitrogen los ntxuav cov pa thiab cov pa roj hauv cov kav dej.

Kev ua haujlwm yuav tsum muaj ib qho - hloov pauv, nrog nitrogen siab tswj ntawm 0.2-0.5MPa. Cov kev cai ntawm qhov chaw suav nrog kev saib xyuas cov pa roj thiab cov ntsiab lus oxygen (nrog nitrogen purity Ntau dua lossis sib npaug li 99.9% lossis 99.99%).

IV. Cov Lus Qhia Txog Kev Kho Mob rauPSA Nitrogen Generators

Txhawm rau kom ntseeg tau ntev - lub sijhawm ua haujlwm ruaj khov thiab zoo ib yam ntawm nitrogen zoo, cov kev saib xyuas niaj hnub no tau pom zoo:

Tsis tu ncua hloov cua lim: Hloov lub tshuab cua compressor ua ntej- lim thiab lim lim txhua 1,000-2,000 teev ua haujlwm kom tsis txhob muaj impurities los ntawm kev sib kis ntawm molecular sieve.

Tshawb xyuas Molecular Sieve Performance: Tshawb xyuas nitrogen purity txhua hli; Yog tias purity poob qis, tshuaj xyuas cov molecular sieve rau kev nqus dej los yog kev laus (hloov yog tias tsim nyog).

Clean Adsorption Ntauwd: Ua kev tu sab hauv ntawm adsorption yees txhua 2-3 xyoos kom tshem tawm cov plua plav thiab ua kom cov roj ntws zoo.

Tshawb xyuas Pipeline Sealing: Tshawb xyuas kev sib khi ntawm cov kav dej sib txuas hauv peb lub hlis twg kom tsis txhob muaj nitrogen to thiab tswj cov khoom siv tau zoo.

Calibrate Cov Cuab Yeej: Calibrate siab ntsuas, ntsuas ntsuas, thiab purity detectors txhua 6 lub hlis los xyuas kom meej parameter xyuas.

Kev tshuaj xyuas txhua hnub: Sau cov ntaub ntawv ua haujlwm (siab, ntws, kub) txhua hnub; tam sim ntawd daws teeb meem txawv txav (xws li, txawv txav siab hloov pauv).

PSA Nitrogen Generators, nrog rau lawv qhuav, impurity -dawb, thiab inert zog, hais txog qhov tsis zoo ntawm txoj kev kho cov kav dej ib txwm muaj. Lawv ua kom cov kav dej huv huv, txo cov kev pheej hmoo ntawm kev nyab xeeb, thiab tau siv dav hauv ntau qhov kev lag luam. Hauv kev siv cov tswv yim, cov kws kho mob yuav tsum ua raws li cov kev xav tau ntawm kev khiav hauj lwm, ua purging / tshem tawm raws li nyob rau hauv - xwm txheej ntawm qhov chaw, thiab ua raws li kev saib xyuas niaj hnub - txhua yam kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm cov kav dej.
