Kugadzirwa kweokisijeni mumaindasitirimidziyo, sezvinoreva zita, midziyo inoshandiswa mukugadzira maindasitiri kugadzira oxygen.
Saka ndeipi nzira yekugadzirwa kweokisijeni mumaindasitiri?
Kazhinji isu tinowanzo shandisa nzira yekugadzira okisijeni nekuora hydrogen peroxide kana potassium permanganate murabhoritari, ine maitiro ekukurumidza kuita, kushanda kuri nyore uye kuunganidzwa kuri nyore kwemaindasitiri ekugadzira okisijeni muchina, asi mutengo wakakura uye haugone kugadzirwa muhombe. uwandu, saka inogona chete kushandiswa murabhoritari.Kugadzirwa kwemaindasitiri kunoda kufunga kuti iyo mbishi jenareta yeokisijeni ndeipi mhando iri nyore kuwana, kana mutengo wakachipa, kana mutengo wakaderera, ungave uchigadzirwa muhuwandu uye kukanganisa kwezvakatipoteredza.
Izvi zvinotevera zvinotsanangura nzira dzakananga dzekugadzirwa kweokisijeni mumaindasitiri.
1. Mhepo inotonhora yekuparadzanisa nzira
Zvinhu zvikuru zvemhepo iokisijeni uye nitrogen.Kushandiswa kweokisijeni uye nitrogen yekubikira nzvimbo kwakasiyana, kugadzirira kweokisijeni kubva kumhepo kunonzi nzira yekuparadzanisa mweya.Chekutanga, mhepo pre-kutonhora, kucheneswa (kubvisa hunyoro hushoma, carbon dioxide, acetylene, hydrocarbons uye mamwe magasi neguruva uye mamwe tsvina mumhepo), uye ipapo kumanikidzwa, kutonhora, kuitira kuti gumi. mhando dzemajenareta eokisijeni mumhepo yemvura.
Zvino, uchishandisa mutsauko pakati penzvimbo dzinofashaira dzeokisijeni nenitrogen, mhepo yemvura inoputika uye inomisikidzwa kakawanda mushongwe yedistillation kuti iparadzanise oxygen nenitrogen.Kana iwe ukawedzera mamwe maturusi ekuwedzera, unogona zvakare kubvisa argon, neon, helium, krypton, xenon uye mamwe asingawanzo inert magasi ane zvishoma mumhepo.Iyo okisijeni inogadzirwa nemudziyo wekuparadzanisa mhepo inotsikirirwa necompressor, uye pakupedzisira iyo okisijeni yakamanikidzwa inotakurwa mumasilinda ane simba rekuchengetedza, kana kutakurwa zvakananga kumafekitori nemashopu kuburikidza nemapaipi.
2. Molecular sieve okisijeni nzira yekugadzira (adsorption nzira)
Uchishandisa hunhu hwemamorekuru enitrogen akakura kupfuura mamorekuru eokisijeni, okisijeni iri mumhepo inopatsanurwa kunze pachishandiswa sefa yakanyatsogadzirwa.Chekutanga, compressor inomanikidza mweya wakaoma kuburikidza nesefa yemamorekuru kupinda muvacuum adsorber, mamorekuru enitrogen ari mumhepo anovharirwa nesefa yemamorekuru, okisijeni ichipinda muadsorber, kana okisijeni iri mu adsorber yasvika imwe chiyero (kumanikidza kunosvika level), unogona kuvhura vharuvhu yeokisijeni kuburitsa okisijeni.
Mushure menguva yakati rebei, iyo nitrogen yakashongedzwa nesefa yemamolecular inowedzera zvishoma nezvishoma, iyo adsorption simba inopera, uye kuchena kweiyo okisijeni inobuda, saka iyo nitrogen yakashambadzirwa pa molecular seeve inoda kupomba kunze nepombi yevacuum, yozodzokorora. nzira iri pamusoro.Iyi nzira yekugadzirwa kweokisijeni inonziwo adsorption nzira.
