VPSA oxygen ntau lawm txheej txheem

Raws li keeb kwm yav dhau los tam sim no ntawm kev thov kom siab purity thiab siab txaus oxygen, cov txheej txheem sib sib zog nqus cua txias oxygen thiab cov txheej txheem PSA tau ntsib ntau yam teeb meem ntawm kev siv hluav taws xob, kev nqis peev thiab kev ua haujlwm hauv av, thiabVPSA (Nqus Siab Swing Adsorption) tshuab, los ntawm kev tsim txiaj ntawm nws qhov qis -siab inlet, lub tshuab nqus tsev daws teeb meem, lub zog-txuag thiab siab-efficiency, tau maj mam hloov cov txheej txheem ib txwm ua raws li cov kev xaiv loj rau nruab nrab thiab loj kev lag luam tej yaam num thiab regional centralized oxygen mov systems.

Nyob rau hauv niaj hnub nruab nrab thiab loj -scale oxygen mov scenarios, VPSA (Vacuum Pressure Swing Adsorption) thev naus laus zis tau dhau los ua txoj hauv kev thev naus laus zis tseem ceeb rau kev hloov pauv cov txheej txheem PSA thiab kua oxygen mov vim nws qhov kev siv hluav taws xob tsawg, roj ntau lawm thiab kev ruaj ntseg.

Kev soj ntsuam ntawm txoj haujlwm ua haujlwm

VPSA txheej txheem yog qhov tseem ceeb ntawm kev paub txog kev sib cais ntawm cov pa thiab nitrogen hauv huab cua nyob rau hauv cov xwm txheej qis -siab adsorption thiab lub tshuab nqus tsev daws teeb meem:

Adsorption theem: nyob rau hauv atmospheric siab los yog me ntsis zoo siab, huab cua yog xa mus rau lub adsorption ntauwd tom qab pretreatment, thiab molecular sieve (xws li, LiX) adsorbs nitrogen nyob rau hauv cov huab cua nyob rau hauv nyiam rau cov pa enriched thiab ces nkag mus rau hauv cov kav dej ntau lawm;

Resolution theem: lub adsorption ntauwd yog hloov mus rau lub xeev ntawm suction ntawm lub tshuab nqus tsev twj tso kua mis (-0.05 rau -0.09%), uas yog thawj theem ntawm cov txheej txheem . 0.05~-0.09MPa), lub adsorbed nitrogen yog daws thiab tso tawm, thiab lub molecular sieve yuav tsum regenerated;

Adsorption ntauwd alternating ua hauj lwm: feem ntau yog siv ob lub pej thuam los yog plaub ntauwd qauv kom paub tas mus li thiab ruaj khov oxygen tso zis.

Qhov tseem ceeb sib txawv nrog cov txheej txheem PSA

Xaus: VPSA thev naus laus zis tshwj xeeb tshaj yog tsim nyog rau qhov siab txaus, cov pa oxygen txuas ntxiv, lub zog- qhov xwm txheej ceev, xws li smelters, cov chaw kho mob hauv cheeb tsam oxygen, loj - cov nroj tsuag kho dej thiab lwm yam.

Lub luag haujlwm tseem ceeb ntawm cov khoom siv molecular sieve

Molecular sieve (xws li LiX lithium{0}}raws li molecular sieve) yog "cov khoom siv tseem ceeb" ntawm VPSA thev naus laus zis, thiab nws lub peev xwm xaiv adsorption ntawm nitrogen txiav txim siab qhov ua tau zoo ntawm cov pa oxygen tsim:

Qhov zoo ntawm kev xaiv LiX:

Muaj zog nitrogen adsorption muaj peev xwm, siab oxygen throughput tus nqi;
