PSA matsa lamba lilo adsorption nitrogen samar da manufa
Carbon molecular sieve can adsorb oxygen and nitrogen in the air at the same time, and its adsorption amount also increases with the increase of pressure, and there is no obvious difference in the equilibrium adsorption amount of oxygen and nitrogen at the same pressure. Sabili da haka, yana da wahala a kammala ingantaccen rabuwar iskar oxygen da nitrogen ta canjin matsa lamba kadai. Idan an ƙara yin la'akari da ƙimar talla, ana iya bambanta halayen haɓakar oxygen da nitrogen da kyau. Diamita na ƙwayoyin iskar oxygen ya yi ƙasa da na ƙwayoyin nitrogen, don haka adadin yaɗuwar ya ninka sau ɗaruruwan sauri fiye da na nitrogen. Saboda haka, gudun carbon molecular sieve adsorbing oxygen shi ma yana da sauri sosai, kuma tallan ya kai fiye da 90% a cikin kimanin minti 1; yayin da adadin adadin nitrogen ya kasance kusan kashi 5% a wannan lokacin, don haka tallan a wannan lokacin shine mafi yawan iskar oxygen, sauran kuma yawanci nitrogen ne. Ta wannan hanyar, idan an sarrafa lokacin adsorption a cikin minti 1, ana iya fara raba oxygen da nitrogen. A wasu kalmomin, adsorption da desorption ana samun su ta hanyar bambancin matsa lamba, adsorption lokacin da matsa lamba ya karu, da lalata lokacin da matsa lamba ya ragu. Bambance-bambancen da ke tsakanin oxygen da nitrogen ya dogara da bambanci a cikin adadin adsorption na biyu, wanda aka samu ta hanyar sarrafa lokacin talla. Idan an sarrafa lokacin ya zama ɗan gajeren lokaci, oxygen an cika shi sosai, kuma nitrogen ba ta rigaya ba, an dakatar da tsarin tallan.
Ka'idar Cryogenic Air Rabe Nitrogen Samar da
Cryogenic nitrogen samar iya samar ba kawai nitrogen amma kuma ruwa nitrogen, wanda ya gana tsari bukatun na ruwa nitrogen, kuma za a iya adana a cikin ruwa nitrogen ajiya tankuna. Lokacin da aka sami nauyin nitrogen mai tsaka-tsaki ko kuma an gyara kayan aikin raba iska, nitrogen na ruwa a cikin tanki na ajiya ya shiga cikin vaporizer kuma an yi zafi, sa'an nan kuma aika zuwa samfurin nitrogen bututun don saduwa da buƙatar nitrogen na sashin tsari. Zagayowar aiki na samar da nitrogen na cryogenic (yana nufin tazara tsakanin manyan dumama guda biyu) gabaɗaya ya fi shekara 1, don haka samar da nitrogen na cryogenic gabaɗaya ba a ɗaukarsa azaman jiran aiki. Duk da haka, matsi na matsa lamba samar da nitrogen zai iya samar da nitrogen kawai, ba tare da jiran aiki ba, kuma saitin kayan aiki guda ɗaya ba zai iya ba da garantin ci gaba da aiki na dogon lokaci-.
Ka'idar Samar da Nitrogen Rabewar Membrane Air
Bayan an matsa kuma tace ta hanyar kwampreso, iska ta shiga cikin tace polymer membrane. Saboda daban-daban solubility da watsawa coefficients na daban-daban iskar gas a cikin membrane, da dangi permeation rates na daban-daban gas a cikin membrane sun bambanta. Bisa ga wannan sifa, ana iya raba iskar gas iri-iri zuwa "gas mai sauri" da "gas mai jinkirin".
Lokacin da gauraye gas ne a karkashin mataki na matsa lamba bambance-bambance a bangarorin biyu na membrane, gas da in mun gwada da sauri permeation rates, kamar ruwa, hydrogen, helium, hydrogen sulfide, carbon dioxide, da dai sauransu, wuce ta cikin membrane da aka wadãtar a kan permeation gefen na membrane, yayin da iskar gas tare da in mun gwada da jinkirin permeation rates, kamar methane, carbon monoxide, carbon monoxide da argon a can retained da nitrogen da argon. manufar cakuda gas rabuwa.
