Cov pa hluav taws xob muaj ntau cov pa khib nyiab nrog ntau yam hydrogen.Kev sib cais thiab kev ua kom huv ntawm hydrogen kuj yog ib qho ntawm cov kev lag luam ntxov tshaj plaws ntawm PSA thev naus laus zis.
Lub hauv paus ntsiab lus ntawm PSA kev sib cais ntawm cov roj sib tov yog tias lub peev xwm adsorption ntawm adsorbent rau cov khoom siv roj sib txawv hloov nrog kev hloov siab.Cov impurity Cheebtsam nyob rau hauv lub inlet gas raug tshem tawm los ntawm high-pressure adsorption, thiab cov impurities yog desorbed los ntawm kev txo siab thiab kub nce.Lub hom phiaj ntawm kev tshem tawm impurities thiab rho tawm cov khoom ntshiab yog ua tiav los ntawm kev hloov siab thiab kub.
PSA hydrogen ntau lawm siv JZ-512H molecular sieve adsorbent cais cov nplua nuj hydrogen los tsim hydrogen, uas yog ua tiav los ntawm kev hloov siab ntawm adsorption txaj.Vim tias hydrogen nyuaj heev rau adsorb, lwm cov roj (uas tuaj yeem hu ua impurities) yog ib qho yooj yim los yog yooj yim rau adsorbed, yog li hydrogen nplua nuj roj yuav raug tsim thaum nws nyob ze rau qhov nkag siab ntawm cov pa kho.Cov impurities raug tso tawm thaum lub sij hawm desorption (regeneration), thiab lub siab maj mam txo mus rau desorption siab
Lub adsorption ntauwd hloov ua cov txheej txheem ntawm adsorption, siab.equalization thiab desorption kom ua tiav kev tsim cov hydrogen tas li.nplua nuj hydrogen nkag mus rau hauv lub cev nyob rau hauv ib tug tej yam siab.Cov nplua nuj hydrogen hla dhau lub adsorption ntauwd uas muaj qhov tshwj xeeb adsorbent los ntawm qab mus rau sab saum toj.Co / CH4 / N2 yog khaws cia rau saum npoo ntawm cov adsorbent raws li qhov muaj zog adsorption tivthaiv, thiab H2 nkag mus rau hauv txaj raws li cov khoom siv adsorption.Cov khoom siv hydrogen sau los ntawm sab saum toj ntawm lub adsorption ntauwd yog tso tawm sab nraud ntawm ciam teb.Thaum cov adsorbent hauv txaj yog saturated nrog CO / CH4 / N2, cov nplua nuj hydrogen hloov mus rau lwm cov adsorption yees.Nyob rau hauv tus txheej txheem ntawm adsorption desorption, ib tug tej yam siab ntawm cov khoom hydrogen tseem tshuav nyob rau hauv lub adsorbed ntauwd.Qhov no ntawm cov ntshiab hydrogen yog siv los sib npaug thiab yaug lub siab sib npaug ntawm cov yees cia li desorbed.Qhov no tsis tsuas yog ua rau kev siv cov hydrogen ntxiv nyob rau hauv lub adsorption ntauwd, tab sis kuj ua rau lub siab nce ceev hauv lub adsorption ntauwd, ua rau lub zog qaug zog hauv lub adsorption ntauwd, thiab ua tiav lub hom phiaj ntawm kev sib cais hydrogen.
JZ-512H molecular sieve tuaj yeem siv tau kom tau txais cov purity siab hydrogen.
