Nkhani

Oxygen ndi mpweya wosanunkha, wosakoma, wopanda mtundu womwe umapezeka pozungulira ife mumpweya womwe timapuma.Ndilo chofunikira chopulumutsa moyo kwa zamoyo zonse.Koma Coronavirus yasintha zinthu zonse tsopano.

Mpweya wamankhwala ndi chithandizo chofunikira kwa odwala omwe mulingo wa okosijeni m'magazi awo ukuchepa.Ndiwofunikanso kuchiza malungo oopsa, chibayo ndi mavuto ena azaumoyo.Komabe, nthaŵi zimene sizinachitikepo n’kale lonse zatiphunzitsa kuti kaŵirikaŵiri simapezeka kwa anthu amene amafunikira kwambiri.Ndipo, ngati ikupezeka kwinakwake, nthawi zambiri imakhala yokwera mtengo kwa omwe ali ndi mwayi ndipo nthawi zambiri imakhala yovuta.

Kufalitsa nkhani za mliri wa COVID-19 kwachititsa mantha chifukwa cha kugwa kwa chipatala ku India.Kuperewera kwa mabedi a ICU kapena ma ventilator ndi enieni koma kuwonjezera mabedi osakonza mpweya sikungathandize.Ichi ndichifukwa chake zipatala zonse ziyenera kuyang'ana kwambiri pakupanga makina a okosijeni azachipatala ndikuyika majenereta apamalo omwe amapereka mpweya wosadukiza pakafunika.

Ukadaulo wa PSA (Pressure Swing Adsorption) ndi njira yothandiza yopangira mpweya wa Oxygen pazachipatala ndipo ikugwiritsidwa ntchito kwa zaka zopitilira 30 m'makampani azachipatala.

Kodi ma Medical Oxygen Generator amagwira ntchito bwanji?

Mpweya wozungulira uli ndi 78% Nitrogen, 21% Oxygen, 0.9% Argon ndi 0.1% trace ya mpweya wina.Ma MVS omwe ali pa malo Opangira Oxygen Oxygen amalekanitsa mpweya uwu ku Compressed Air kudzera mu njira yotchedwa Pressure Swing Adsorption (PSA).

Pochita izi, nayitrogeni imasiyanitsidwa, zomwe zimapangitsa kuti 93 mpaka 94% ya oxygen ikhale yofanana ndi mpweya wotuluka.Njira ya PSA imakhala ndi nsanja zodzaza zeolite, ndipo zimatengera kuti mipweya yosiyanasiyana imakhala ndi malo oti akopeke ndi malo olimba osiyanasiyana mocheperapo kapena kwambiri.Izi zimachitika ndi nayitrogeni, nawonso-N2 amakopeka ndi zeolite.Mpweya ukakanikizidwa, N2 imatsekeredwa m'makola a crystalline a zeolite, ndipo okosijeniwo sakhala otsatsa pang'ono ndikupitilira malire a bedi la zeolite ndipo pamapeto pake amabwereranso mu thanki ya okosijeni.

Mabedi awiri a zeolite amagwiritsidwa ntchito palimodzi: Imodzi imasefa mpweya pansi pa kupanikizika mpaka unyowe ndi nayitrogeni pamene mpweya ukudutsa.Fyuluta yachiwiri imayambanso kuchita chimodzimodzi pomwe yoyamba ikubwezedwa pamene nayitrogeni imatulutsidwa pochepetsa kupanikizika.Mpweyawu umabwerezabwereza, ndikusunga mpweya mu thanki.
