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

Incazelo emfushane:

Izingxenye eziyinhloko emoyeni i-nitrogen ne-oxygen, 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), dweba inqubo efanele, futhi wenze i-nitrogen. kanye nokuhlukaniswa kwe-oxygen ukuze uthole umoya-mpilo.

Isimiso sokusebenza

Izingxenye eziyinhloko emoyeni i-nitrogen ne-oxygen, 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), ukuklama inqubo efanele, futhi wenze i-nitrogen. kanye nokuhlukaniswa komoya-mpilo ukuze kutholwe umoya-mpilo.I-nitrojeni ku-zeolite ikhono le-molecular sieve adsorption lingcono kune-oxygen (i-nitrogen ion kanye ne-molecular sieve surface force force strong), lapho umfutho womoya usesimweni esinombhede we-adsorption we-zeolite molecular adsorbent, i-nitrogen nge-molecular sieve adsorption , i-oksijini encane ngokukhangisa, ukugxila kanye nokugeleza kumbhede we-adsorption wesigaba segesi, ukuhlukaniswa komoyampilo ne-nitrogen ukuze uthole umoya-mpilo.Lapho isisefo se-molecular adsorption nitrogen ukuze sigcwale, misa umoya futhi unciphise ukucindezela kombhede we-adsorption, i-molecular sieve adsorption nitrogen ishintshashintsha, i-molecular sieve regeneration futhi ingaphinda isetshenziswe.Lapho imibhede emibili noma ngaphezulu ye-adsorption ishintsha umsebenzi ngokushintshana, umoya-mpilo ungaqhubeka ngokuqhubekayo.kukhiqizwa.

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 u-90-95% we-oxygen (i-oksijeni embi kakhulu ingu-95.6%, enye ingxenye i-argon), eyaziwa nangokuthi i-oxygen rich.Uma kuqhathaniswa namayunithi okuhlukanisa umoya we-cryogenic, lokhu kungakhiqiza okungaphezu kwe-99.5% okuhlushwa kwe-oxygen.

Inqubo yedivayisi

Umbhede we-adsorption we-psa air separation oxygen plant kumele ube nezinyathelo ezimbili zokusebenza.I-Adsorption ne-resolution.Ukuze uqhubeke nokuthola igesi yomkhiqizo, ngokuvamile imibhede engaphezu kwemibili i-adsorption ifakwa emshinini wokukhiqiza umoya-mpilo, futhi ngokombono wokusetshenziswa kwamandla kanye nokusetshenziswa kwamandla. Ukuzinza, ezinye izinyathelo ezisizayo ezidingekayo ziyamiswa. Umbhede ngamunye we-adsorption ngokuvamile kufanele udlulele kwi-adsorption, ukukhululwa kwengcindezi, ukuphuma noma ukuwohloka kabusha, ukushintshwa okushaywayo kanye nezinyathelo zokuqinisa ukulinganisa kokucindezela, ukusebenza okuphindaphindiwe ngezikhathi ezithile. Ngesikhathi esifanayo, umbhede ngamunye we-adsorption ungaphakathi ngokulandelana kwawo. izinyathelo ezahlukene zokusebenza, ngaphansi kokulawulwa kwe-PLC ukushintsha isikhathi, ukuze ukusebenza okudidiyelwe kombhede we-adsorption, ekusebenzeni kuyanyakaziswana, ukuze idivayisi ye-adsorption swing yokucindezela isebenze kahle, ukufinyelela okuqhubekayo kwegesi yomkhiqizo.Ezinye izingxenye zokulandelela emoyeni. kumele futhi kucatshangelwe inqubo yokuhlukanisa yangempela.I-Carbon dioxide namanzi ku-adso evamileumthamo we-rbent adsorption ngokuvamile mkhulu kakhulu kune-nitrogen nomoya-mpilo, ungagcwaliswa embhedeni we-adsorption nge-adsorbent efanele (noma ukusetshenziswa kwe-oxygen adsorbent ngokwayo) ukuze uyenze 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 kuphezulu.Inkambiso yamanje ukusebenzisa ama-oxygen sorbent asebenza kahle kakhulu ukuze kuncishiswe inani lemibhoshongo esetshenziswayo futhi kusetshenziswe imijikelezo yokusebenza emifushane ukuze kwandiswe ukusebenza kahle kwezitshalo nokunciphisa ukutshalwa kwezimali. .
