Samar da iskar oxygen na masana'antukayan aiki, kamar yadda sunan ke nunawa, kayan aiki ne da ake amfani da su wajen samar da masana'antu don samar da iskar oxygen.
To, menene hanyar samar da iskar oxygen na masana'antu?
Kullum muna amfani da hanyar yin iskar oxygen ta hanyar lalata hydrogen peroxide ko potassium permanganate a cikin dakin gwaje-gwaje, wanda ke da halayen saurin amsawa, aiki mai sauƙi da kuma tarin kayan aikin oxygen na masana'antu, amma farashin yana da girma kuma ba za a iya samar da shi da girma ba. yawa, don haka za a iya amfani da shi kawai a cikin dakin gwaje-gwaje.Samar da masana'antu yana buƙatar yin la'akari da ko injin samar da iskar oxygen abin da ke da sauƙin samu, ko farashin yana da arha, ko farashin yana da ƙasa, ko ana iya samar da shi da yawa da kuma tasirin muhalli.
Mai zuwa yayi bayanin takamaiman hanyoyinmasana'antu oxygen samar.
1. Hanyar daskarewa iska
Babban abubuwan da ke cikin iska sune oxygen da nitrogen.Yin amfani da iskar oxygen da nitrogen na tafasa ya bambanta, shirye-shiryen oxygen daga iska ana kiran hanyar rabuwar iska.Da farko, da iska pre-sanyi, tsarkakewa (don cire karamin adadin danshi, carbon dioxide, acetylene, hydrocarbons da sauran gas da ƙura da sauran ƙazantar a cikin iska), sa'an nan matsa, sanyaya, sabõda haka, a saman goma. nau'ikan masu samar da iskar oxygen zuwa iska mai ruwa.
Sa'an nan kuma, ta yin amfani da bambanci tsakanin wuraren tafasa na oxygen da nitrogen, iska mai ruwa yana ƙafe kuma yana daɗaɗa sau da yawa a cikin hasumiya na distillation don raba oxygen da nitrogen.Idan kun ƙara wasu ƙarin na'urori, zaku iya fitar da argon, neon, helium, krypton, xenon da sauran iskar gas ɗin da ba kasafai ake samun su ba waɗanda ke ɗauke da kaɗan a cikin iska.Oxygen din da na’urar kera iskar ta ke samarwa, na’urar kwampreso ta nannade ta ne, sannan a karshe ana loda iskar oxygen din a cikin manyan injinan matsa lamba don adanawa, ko kuma kai tsaye zuwa masana’antu da wuraren bita ta hanyar bututun mai.
2. Hanyar samar da iskar oxygen (hanyar adsorption)
Yin amfani da halayen ƙwayoyin nitrogen da suka fi ƙwayoyin iskar oxygen girma, iskar oxygen da ke cikin iska ta rabu ta amfani da siffa ta musamman da aka ƙera.Na farko, compressor yana tilasta busasshiyar iska ta hanyar sieve na kwayoyin zuwa cikin vacuum adsorber, kwayoyin nitrogen da ke cikin iska ana tallata su ta hanyar sieve na kwayoyin, oxygen cikin adsorber, lokacin da iskar oxygen da ke cikin adsorber ya kai wani adadi (matsi ya kai wani adadi). matakin), zaku iya buɗe bawul ɗin oxygen don sakin iskar oxygen.
Bayan wani ɗan lokaci, nitrogen ɗin da ke daɗaɗɗen ƙwayar ƙwayar ƙwayar cuta a hankali yana ƙaruwa, ƙarfin tallan yana raguwa, kuma tsarkin iskar oxygen ɗin da ake fitarwa yana raguwa, don haka nitrogen ɗin da aka toka akan simintin kwayoyin yana buƙatar fitar da shi ta hanyar famfo, sannan a maimaita. tsarin da ke sama.Wannan hanyar samar da iskar oxygen kuma ana kiranta hanyar adsorption.
