Wumgaqo wokusebenza
Isixhobo sokuvelisa i-VPSA vacuum desorption i-oksijini ikakhulu yenziwe nge-blower, i-vacuum pump, i-valve yokutshintsha, i-adsorber kunye ne-oxygen balance tank.Umoya okrwada ucinezelwa ziingcambu zokuvuthela kwi-adsorber egcwele i-oxygen molecular sieve, apho amanzi, i-carbon dioxide kunye ne-nitrogen zibhengezwa khona ukuvelisa i-oksijini.Xa i-adsorption ifikelela kwinqanaba elithile, i-vacuum pump isetyenziselwa ukucoca amanzi adsorbed, i-carbon dioxide, i-nitrogen kunye nenani elincinane lamanye amaqela egesi ngokulandelelanayo akhutshwe kwaye akhutshwe emoyeni, kwaye i-adsorbent ihlaziywa.La manyathelo enkqubo angentla alawulwa ngokuzenzekelayo yi-PLC kunye nenkqubo yevalve yokutshintsha.

Umsebenzi wokuvuthela ioksijini kwiziko elivulekileyo lomlilo kukuxhasa ukutsha.Injongo yalo kukomeleza inkqubo yokunyibilikisa, ukunciphisa ixesha lokunyibilikisa kunye nokwandisa imveliso yentsimbi yesithando somlilo esivulekileyo.Kuye kwangqinwa ukuba ukuvuthela kweoksijini kwiziko elivulekileyo lomlilo kunokunyusa imveliso yentsimbi ngaphezu kwexesha elinye kwaye kunciphise ukusetyenziswa kwamafutha ngama-33% ~ 50%.
Ioksijini esetyenziswa kwiziko lombane inokukhawulezisa ukunyibilika kwentlawulo yesithando somlilo kunye ne-oxidation yokungcola, oku kuthetha ukuba ukuvuthuza kweoksijini kwisithando sombane akunakuphucula kuphela umthamo wokuvelisa kodwa nokuphucula umgangatho okhethekileyo.Ukusetyenziswa kwe-oksijeni ngetoni nganye yensimbi yesithando sombane kuyahluka ngokweentlobo ezahlukeneyo zetsimbi eziza kuncibilika, umzekelo, ukusetyenziswa kwe-oksijini ngetoni ye-carbon structural steel yi-20-25m3, ngelixa i-alloy iron ephezulu i-25-30m3.I-oxygen concentration efunekayo yi-90% ~ 94%.
Ukuqhuma kwesithando somlilo esineoksijini ephuculweyo kunokunciphisa kakhulu i-coking kunye nokwandisa imveliso.Ngokutsho kwezibalo, xa i-oxygen concentration inyuswe nge-1%, i-iron imveliso inokunyuswa nge-4% - 6%, kwaye i-coking ingancitshiswa nge-5% - 6%.Ngokukodwa xa intsimbi esekwe emalahleni yenza iqondo lokutofa kwamanzi lifikelela kwi-300kg, isixa seoksijini esihambelanayo yi-300m3 / intsimbi.
Xa ioksijini ingeniswa kwinkqubo yokunyibilika kwezinyithi ezingenayo i-ferrous, isulfure inokutshiswa ngokupheleleyo, ubushushu obunyibilikayo bunokugcinwa kwaye isantya sokunyibilika sinokunyuswa.Ukuthatha ubhedu njengomzekelo, i-oksijini ephuculweyo ye-copper smelting ingagcina amandla angama-50%, oko kukuthi, phantsi kokusetyenziswa kwamafutha afanayo, ukuveliswa kobhedu kunokuphindwa kabini.
