Umgaqo wokusebenza

Amacandelo aphambili emoyeni yinitrogen kunye neoksijini, kusetyenziswa ubushushu be-ambient, initrogen kunye neoksijini emoyeni kwi-zeolite molecular sieve (ZMS) ukusebenza kwe-adsorption yahlukile (i-oksijeni inokudlula kunye ne-nitrogen adsorption), ukuyila inkqubo efanelekileyo, kwaye wenze i-nitrogen. kunye ne-oksijini yokwahlula ukufumana i-oksijeni.I-nitrojeni kwi-zeolite i-molecular sieve adsorption ingcono kune-oksijini (i-nitrogen ion kunye ne-molecular sieve surface force force strong), xa uxinzelelo lomoya kwindawo ene-zeolite molecular sieve adsorbent bedsorption bed, i-nitrogen nge-molecular sieve adsorption. , ioksijini encinci nge-adsorption, i-concentration kunye nokuhamba kwi-gas phase adsorption bed, i-oksijini kunye ne-nitrogen yokwahlukana kwe-oxygen. ukuvuselelwa kwe-molecular sieve kwaye ingaphinda isetyenziswe.Xa iibhedi ezimbini okanye ngaphezulu ze-adsorption zitshintsha umsebenzi ngokulandelelana, ioksijini inokuveliswa ngokuqhubekayo.

I-oksijeni kunye ne-nitrogen zineendawo zokubilisa ezifanayo, ezenza kube nzima ukuhlukana, kwaye zityetyiswe kunye emoyeni.Ngoko ke, izixhobo zokuvelisa i-psa oxygen ngokuqhelekileyo zinokufumana kuphela i-90-95% ye-oksijeni (i-oksijini embi kakhulu yi-95.6%, intsalela yi-argon), eyaziwa ngokuba yi-oxygen rich.Xa kuthelekiswa neeyunithi zokuhlukana komoya we-cryogenic, le yokugqibela inokuvelisa ngaphezu kwe-99.5% yoxinaniso lwe-oxygen.

Inkqubo yesixhobo

Ibhedi ye-adsorption ye-psa air separation oxygen plant kufuneka ibe namanyathelo amabini okusebenza.I-Adsorption kunye nesisombululo.Ukuze ufumane igesi yemveliso ngokuqhubekayo, ngokuqhelekileyo iibhedi ezingaphezu kwe-adsorption zifakwe kwisixhobo sokuvelisa i-oksijeni, kunye nombono wokusetyenziswa kwamandla kunye Uzinzo, amanye amanyathelo ayimfuneko ancedisayo asetyenzisiwe.Ibhedi nganye ye-adsorption kufuneka ingene kwi-adsorption, ukukhululwa koxinzelelo, ukukhutshwa okanye ukuvuselelwa koxinzelelo, ukutshintshwa kokugungxulwa kunye namanyathelo okunyusa ukulinganisa uxinzelelo, ukusebenza ngokuphindaphindiweyo okuphindaphindiweyo. Ngexesha elifanayo, ibhedi nganye ye-adsorption ngokulandelelana amanyathelo ahlukeneyo okusebenza, phantsi kolawulo lwe-PLC yokutshintsha ixesha, ukuze ibhedi ye-adsorption isebenze ngokulungelelaniswayo, ekusebenzeni iyagxadazela, ukuze isixhobo soxinzelelo lwe-adsorption siqhube kakuhle, ukufikelela ngokuqhubekayo kwimveliso ye-gas.Other amacandelo omkhondo emoyeni. Kufuneka kwakhona kuqwalaselwe inkqubo yokwahlula yokwenyani.Ikhabhon diokside kunye namanzi kwindawo yesiqhelo adsorbent adsorption umthamo jikelele mkhulu kakhulu kunenitrogen kunye neoksijini, inokuzaliswa ebhedini adsorption efanelekileyo adsorbent (okanye ukusetyenziswa oksijini adsorbent ngokwayo) ukuyenza i-adsorption kunye nokususwa.

Inani leenqaba ze-adsorption ezifunwa sisixhobo sokuvelisa i-oksijini kuxhomekeke kwisikali semveliso ye-oksijini, ukusebenza kwe-adsorbent kunye neengcamango zokuyila inkqubo.Uzinzo lomsebenzi wokusebenza kwe-multi-tower lungcono kakhulu, kodwa utyalo-mali lwezixhobo luphezulu.Intsingiselo yangoku kukusebenzisa i-oxygen sorbents ephezulu yokunciphisa inani leenqaba ze-adsorption kunye nokusebenzisa imijikelo emifutshane yokusebenza ukwandisa ukusebenza kakuhle kwezityalo kunye nokunciphisa utyalo-mali. .
