vpsa yomphakathi wokuhluhluza amonyaniso
Umvuselelo waseVPSA (Vacuum Pressure Swing Adsorption) yekuphakamisa okugcinwa kweoxyjeni ukuchasenqanawe lokungabhedwayo kwiqhutyandzelo lwezi zilondaweni zezi gasi. Umsebenzi omusho olunovutho ungene ngokusebenzisa amathuluzi amahluke amasiphephe esikhoyo ukususa i-oxyjeni kumoya wesintu, ukuze kube ngepurity ephakeme ku-95%. Isistimu sikusebenza ngokubheka kwezinye ezimbili zezindlela zokuhlola nokuhlola ngokwesikhumbuzo, ukuvamukela uphakamiso lwalo we-oxyjeni. Ngokwesiphakamiso sokuncedisiyo, umvuselelo waseVPSA usetyenziswa amakhompi egciniwe nezi vessel ezifilled nge-zeolite, ozicatshulwa ngokubhekelwa i-nitrogeni ngelixa li-oxyjeni lichaze phakathi. Umlilo uqala ngokuba imoya yesintu uzihlola kunye nokudibana ngaphandle kwezi vessel, apho umthuluzi wase-zeolite uzihlola i-nitrogeni, i-carbon dioxide kunye nomoya wesintsi, ukucacisa okanyeleyo lo-oxyjeni. Isistimu sithatha isikhumbuzo sokuhlola ukusetha umthuluzi wase-zeolite, ukwenza ukuba kuhlatywa kwindlela elandelayo. Izisistimu zesikhatsi somlando zazizityenziswa ngokusebenzisa izindaba ezincane ezinikezeli ukuthi ziyongezelele amanani akhothani nokuphakamisana, ukusure ukuba kube kuhlinzekile kunye nokuphakamisana kweoutput. Lezi zisistimu zinezisekelo ukuba zikhethe amandla angcono, kwiqhutyandzelo leyi-000 kunye nesiya lesikhulu lesi-sekhemikali, uzokusetyenziswa amafowethi amaningi kwi-hour, phakathi kokufumaneka kwezingane ezimediwene kunye nemiseko yeminingi. Ukuphakamisana nokuhlinzekile kwe mvuselelo wenziwe ukuba kuhlonishwe ngokupheleleyo kwi-industri yokuthi kudinga uphakamiso olungcono, loku-oxyjeni, njenge-healthcare, uphakamiso lwemita kunye nokuphakama kwamoya wesintsi.
