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), dweba inqubo efanele, futhi wenze i-nitrogen. kanye nokuhlukaniswa komoya-mpilo ukuze kutholwe umoya-mpilo.Ikhono le-nitrojeni ku-zeolite i-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 , umoya-mpilo omncane ngokukhangisa, ukugxilisa ingqondo nokugeleza kumbhede we-adsorption wesigaba segesi, ukuhlukaniswa komoya-mpilo ne-nitrogen ukuze uthole umoya-mpilo.Lapho isisefo se-molecular adsorption nitrogen ukuze sigcwale, misa umoya futhi unciphise ukucindezela kombhede wokukhangisa, i-molecular sieve adsorption nitrogen ishintshile, 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 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

I-adsorption bed ye-psa air separation oxygen plant kumele ibe nezinyathelo ezimbili zokusebenza.I-Adsorption ne-resolution.Ukuze uqhubeke nokuthola igesi yomkhiqizo, ngokuvamile imibhede engaphezu kwemibili ye-adsorption ifakwa kudivayisi yokukhiqiza 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 okuguquguqukayo kanye nezinyathelo zokukhulisa ingcindezi, ukusebenza okuphindaphindiwe ngezikhathi ezithile. Ngesikhathi esifanayo, umbhede ngamunye we-adsorption ungaphakathi ngokulandelana kwawo. izinyathelo zokusebenza ezahlukene, ngaphansi kokulawulwa kwe-PLC yokushintsha 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. kufanele futhi kucatshangelwe inqubo yangempela yokuhlukanisa.I-Carbon dioxide namanzi kumthamo we-adsorbent adsorption evamile ngokuvamile inkulu kakhulu kune-nitrogen nomoya-mpilo, ingagcwaliswa embhedeni we-adsorption nge-adsorbent efanele (noma ukusetshenziswa kwe-oxygen adsorbent ngokwayo) ukuze ikwenze. i-adsorption nokususwa.

Inani lemibhoshongo ye-adsorption edingwa idivayisi yokukhiqiza umoya-mpilo lincike esikalini sokukhiqizwa komoyampilo, ukusebenza kwe-adsorbent kanye nenqubo yokuklama imibono.Ukuqina 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. .
