Cholinga: Sieve ya Carbon Molecular ndi chopangira chatsopano chomwe chinapangidwa m'ma 1970, ndi chinthu chabwino kwambiri chosakhala polar carbon, Carbon Molecular Sieves (CMS) chomwe chimagwiritsidwa ntchito kulekanitsa nayitrogeni wowonjezera mpweya, pogwiritsa ntchito kutentha kwachipinda chotsika kutsika kwa nayitrogeni, kuposa kuzizira kwanthawi yayitali. Kuthamanga kwa nayitrogeni kumakhala ndi ndalama zochepa zogulira, Kuthamanga kwakukulu kwa nayitrogeni komanso mtengo wotsika wa nayitrogeni. Chifukwa chake, ndi makampani opanga uinjiniya omwe amakonda kukakamiza kugwedezeka (PSA) kupatukana kwa nayitrogeni wolemera, nayitrogeni uyu amagwiritsidwa ntchito kwambiri mumakampani opanga mankhwala, mafuta ndi gasi, mafakitale amagetsi, mafakitale azakudya, mafakitale a malasha, mafakitale ogulitsa mankhwala, mafakitale a chingwe, zitsulo. kutentha mankhwala, mayendedwe ndi kusunga ndi zina.

Mfundo yogwirira ntchito: Sieve ya carbon molecular ndikugwiritsa ntchito mawonekedwe owunikira kuti akwaniritse kulekanitsa kwa oxygen ndi nayitrogeni. Mu molecular sieve adsorption ya gasi wodetsedwa, yayikulu ndi mesoporous imangosewera gawo la tchanelo, ma molekyulu adsorbed amatengedwa kupita ku ma micropores ndi ma submicropores, ma micropores ndi ma submicropores ndiye kuchuluka kwenikweni kwa adsorption. Monga momwe tawonetsera m'chithunzi chapitachi, sieve ya carbon molecular ili ndi ma micropores ambiri, omwe amalola kuti mamolekyu okhala ndi kukula kochepa kwa kinetic afalikire mofulumira mu pores, ndikulepheretsa kulowa kwa ma molekyulu akuluakulu. Chifukwa cha kusiyana kwa chiwerengero cha kufalikira kwa ma molekyulu a gasi amitundu yosiyanasiyana, zigawo za mpweya wosakaniza zimatha kupatulidwa bwino. Chifukwa chake, kugawa kwa ma micropores mu sieve ya carbon molecular kuyenera kuyambira 0.28 nm mpaka 0.38nm malinga ndi kukula kwa molekyulu. Mkati mwa kukula kwa ma micropore, mpweya ukhoza kufalikira mofulumira ku pore kupyolera mu pore orifice, koma nayitrogeni ndi yovuta kudutsa pore orifice, kuti akwaniritse kulekanitsa kwa mpweya ndi nayitrogeni. Micropore pore kukula ndi maziko a mpweya maselo sieve kulekana kwa mpweya ndi nayitrogeni, ngati pore kukula ndi lalikulu kwambiri, mpweya ndi nayitrogeni mosavuta kulowa maselo sieve micropore, nawonso sangakhoze kuchita mbali ya kulekana; Kukula kwa pore ndi kochepa kwambiri, mpweya, nayitrogeni sungathe kulowa mu micropore, komanso sangatenge gawo la kulekana.

Mpweya wolekanitsa mpweya wa carbon molecular sieve nitrogen: chipangizochi chimadziwika kuti makina a nayitrogeni. Njira yaukadaulo ndi kukakamiza swing adsorption njira (njira ya PSA mwachidule) pakutentha koyenera. Pressure swing adsorption ndi njira yotsatsira ndi kupatukana popanda gwero la kutentha. Kuchuluka kwa ma adsorption a carbon molecular sieve to adsorbed components (makamaka ma oxygen molecule) amadsorbed panthawi ya pressurization ndi kupanga gasi chifukwa cha mfundo yomwe ili pamwambayi, ndi desorption panthawi ya depressurization ndi utsi, kuti apangenso mpweya wa carbon molecular sieve. Nthawi yomweyo, nayitrogeni wolemera mu bedi gasi gawo amadutsa bedi kukhala mankhwala mpweya, ndipo sitepe iliyonse ndi ntchito cyclic. Kugwira ntchito mozungulira kwa njira ya PSA kumaphatikizapo: kuthamangitsa kuthamanga ndi kupanga gasi; Kupanikizika kwa yunifolomu; Kutsika pansi, kutopa; Ndiye kuthamanga, kupanga gasi; Magawo angapo ogwira ntchito, kupanga cyclic operation process. Malingana ndi njira zosiyanasiyana zotsitsimutsa ndondomekoyi, ikhoza kugawidwa mu njira yotsitsimutsa vacuum ndi ndondomeko yokonzanso mlengalenga. PSA nayitrogeni kupanga makina zipangizo malinga ndi zosowa za owerenga angaphatikizepo mpweya compression kuyeretsedwa dongosolo, kuthamanga swing adsorption dongosolo, valavu dongosolo ulamuliro dongosolo (vacuum regeneration amafunikanso kukhala vacuum mpope), ndi nayitrogeni dongosolo kupereka.
