Kugadzirwa kweokisijeni inzira yakakosha mumaindasitiri akasiyana, kubva kukurapa kusvika kumaindasitiri ekushandisa. Nzira mbiri dzakakurumbira dzinoshandiswa pachinangwa ichi ndedzePSA (Pressure Swing Adsorption) uye VPSA (Vacuum Pressure Swing Adsorption). Nzira mbiri idzi dzinoshandisa sefa dzemamorekuru kuparadzanisa okisijeni kubva kumhepo, asi dzinosiyana mumashandisirwo adzo nemashandisirwo.
PSA Oxygen Production
PSA okisijeni jenaretainosanganisira kushandiswa kwema molecular sieves kusarudza adsorb nitrogen kubva kumhepo pasi pekumanikidzwa kukuru uye kuisunungura pasi pekumanikidzwa kwakaderera. Iyi nzira ndeye cyclical, inobvumira kuenderera mberi kwekugadzirwa kweokisijeni. Iyo sisitimu inowanzo sanganisira mhepo compressor yekupa inodiwa yakakwirira-kudzvanywa mhepo, molecular sieve mubhedha, uye yekudzora sisitimu yekutonga adsorption uye desorption kutenderera.
Izvo zvakakosha zvePSA system zvinosanganisira air compressor, molecular sieve bed, uye control system. Iyo compressor yemhepo inopa iyo yakanyanya-kudzvanywa mhepo, iyo inopfuura nepakati molecular sieve bed. Iyo molecular sieve inoshambadza nitrogen, ichisiya oxygen kuti iunganidzwe. Mushure mokusvika pakuzara, kudzvinyirirwa kunoderedzwa, zvichiita kuti nitrogen isunungurwe uye sieve idzokororwe patsva kutenderera kunotevera.
VPSA Oxygen Production
VPSA, kune rumwe rutivi, inoshanda pasi pevacuum mamiriro ekusimudzira kushanda kweiyo molecular sieve's adsorption uye desorption maitiro. Iyi nzira inoshandisa musanganiswa wemamolecular sieves uye vacuum pombi kuti uwane yakakwirira kuchena mazinga eokisijeni. Iyo VPSA oxygen chirimwa chinosanganisira vacuum pump, molecular sieve bed, uye control system.
Iyo VPSA maitiro anotanga nemhepo inodhonzwa musystem pasi pevacuum mamiriro. Iyo molecular sieve inoshambadza nitrogen uye kumwe kusvibiswa, ichisiya oxygen. Kamwe sieve yazara, vacuum inoshandiswa kusunungura magasi adsorbed, kudzorerazve sieve kuti iwedzere kushandiswa.
Kuenzanisa uye Zvikumbiro
Ose PSA uye VPSA anoshanda mukugadzira yakakwira-kuchena okisijeni, asi inosiyana mune yavo yekushandisa zvinodiwa uye chiyero. Masisitimu ePSA anowanzo madiki uye anotakurika, zvichiita kuti akwanise kunyorera uko nzvimbo ishoma, senge zvivakwa zvekurapa kana madiki maindasitiri. VPSA masisitimu, nepo akakura uye akaomarara, anokwanisa kuburitsa yakakwira mavhoriyamu eokisijeni uye anowanzoshandiswa mumaindasitiri makuru ekushandisa.
Panyaya yekushanda, VPSA masisitimu anowanzo wedzera simba-rinoshanda nekuda kwevacuum mamiriro, ayo anoderedza simba rinodiwa pakubvisa. Nekudaro, yekutanga kuseta uye mutengo wekushandisa weVPSA masisitimu wakakwira uchienzaniswa nePSA masisitimu.
Mhedziso
PSA uye VPSA maindasitiri okisijeni jenareta inopa yakavimbika uye inoshanda nzira dzekugadzirwa kweokisijeni, imwe neimwe iine zvayakasiyana zvakanakira uye mashandisiro. Sarudzo pakati pezviviri izvi kazhinji zvinoenderana nezvinodiwa chaizvo zvekushandisa, kusanganisira huwandu hweokisijeni inodiwa, chiyero chekuchena chinodiwa, uye nzvimbo iripo uye bhajeti. Nzira mbiri idzi dzinobatsira zvakanyanya kune zvakasiyana-siyana zvinodiwa zvemaindasitiri uye zvipatara, kuve nechokwadi chekugadzika kweokisijeni kwainonyanya kudiwa.
