I-VPSAO vacuum pressure swing adsorption imishini yokukhiqiza umoya-mpilo

I-VPSAO vacuum pressure swing adsorption imishini yokukhiqiza i-oxygen Isithombe esifakiwe

Incazelo emfushane:

Izingxenye eziyinhloko ezisemoyeni i-nitrogen ne-oxygen, zisebenzisa izinga lokushisa elizungezile, i-nitrogen nomoya-mpilo emoyeni ku-zeolite molecular sieve (ZMS) ukusebenza kwe-adsorption kuhlukile (i-oksijini ingadlula kanye ne-nitrogen adsorption), iklame inqubo efanele, futhi yenza ukuhlukaniswa kwe-nitrogen nomoya-mpilo ukuze uthole umoya-mpilo.

Isimiso sokusebenza

Izingxenye eziyinhloko emoyeni i-nitrogen ne-oksijeni, kusetshenziswa izinga lokushisa elizungezile, i-nitrogen nomoya-mpilo emoyeni ku-zeolite molecular sieve (ZMS) ukusebenza kwe-adsorption kuhlukile (i-oksijeni ingadlula kanye ne-nitrogen adsorption), iklame inqubo efanele, futhi yenza ukuhlukaniswa kwe-nitrogen nomoya-mpilo ukuze uthole umoya-mpilo. lapho ingcindezi yomoya esesimweni esinombhede we-adsorption we-molecular ye-zeolite, i-nitrogen nge-molecular sieve adsorption, umoya-mpilo omncane nge-adsorption, ukugxila kanye nokugeleza kumbhede we-adsorption wesigaba segesi, ukuhlukaniswa komoya-mpilo kanye ne-nitrogen ukuze uthole umoya-mpilo. i-adsorption nitrogen change ixazululiwe, i-molecular sieve regeneration futhi ingaphinda isetshenziswe.Lapho imibhede emibili noma ngaphezulu ye-adsorption ishintsha umsebenzi ngokushintshana, umoya-mpilo ungakhiqizwa ngokuqhubekayo.

I-oksijeni ne-nitrogen zinamaphuzu abilayo afanayo, okwenza kube nzima ukuhlukana, futhi ahlanganiswe ndawonye emkhathini.Ngakho-ke, imishini yokukhiqiza umoya-mpilo ye-psa ngokuvamile ingathola kuphela i-90-95% ye-oksijeni (i-oksijini engalungile ngokweqile i-95.6%, enye i-argon), eyaziwa nangokuthi i-oxygen ecebile.Uma kuqhathaniswa namayunithi okuhlukanisa umoya we-cryogenic, ukuhlushwa kwe-oksijini kwe-99% okungaphezu kwe-99.5.

Inqubo yedivayisi

I-adsorption bed ye-psa air separation oxygen plant kumele ibe nezinyathelo ezimbili zokusebenza.I-Adsorption ne-resolution.Ukuze uqhubeke uthole igesi yomkhiqizo, ngokuvamile imibhede ye-adsorption engaphezu kwemibili ifakwe kudivayisi yokukhiqiza umoya-mpilo, futhi ngokombono wokusetshenziswa kwamandla nokuzinza, ezinye izinyathelo zokusiza ezidingekayo ziyamiswa.I-adsorption ne-resolution. ukuvuselelwa, ukushintshwa okuguquguqukayo kanye nezinyathelo zokuqinisa ukulinganisa kwengcindezi, ukusebenza okuphindaphindiwe ngezikhathi ezithile. Ngesikhathi esifanayo, umbhede ngamunye we-adsorption ngokulandelana kwezinyathelo zokusebenza ezahlukene, ngaphansi kokulawulwa kwe-PLC yokushintsha isikhathi, ukuze ukusebenza okudidiyelwe kwe-adsorption eminingana, ekusebenzeni kuyaphazamiseka komunye nomunye, ukuze idivayisi yokukhangisa yokushintsha ingcindezi ikwazi ukusebenza kahle, iphinde ilandelele izingxenye zomoya ukuze kucatshangelwe ukufinyelela okuqhubekayo. inqubo yokuhlukanisa.I-Carbon dioxide namanzi kumthamo ovamile we-adsorbent adsorption ngokuvamile kukhulu kakhulu kune-nitrogen nomoya-mpilo, angagcwaliswa embhedeni we-adsorption nge-adsorbent efanele (noma ukusetshenziswa kwe-oxygen adsorbent ngokwayo) ukuze ayenze i-adsorption futhi isuswe.

Inani lemibhoshongo ye-adsorption edingwa idivayisi yokukhiqiza umoya-mpilo lincike esikalini sokukhiqizwa komoyampilo, ukusebenza kwe-adsorbent kanye nenqubo yokuklama imibono. Ukuzinza kokusebenza kokusebenza kwemibhoshongo eminingi kungcono uma kuqhathaniswa, kodwa ukutshalwa kwezimali kwemishini kungaphezulu.Inkambiso yamanje ukusebenzisa ama-oxygen sorbent asebenza kahle kakhulu ukuze kuncishiswe inani lemibhoshongo ye-adsorption nokusebenzisa imijikelezo yokusebenza emifushane ukuze kwandiswe ukusebenza kahle kwezitshalo nokunciphisa ukutshalwa kwezimali.
