Sisebenza Njani Isityalo se-Oxygen seVPSA?

I-VPSA, okanye i-Vacuum Pressure Swing Adsorption, iteknoloji entsha esetyenziselwa ukuveliswa kwe-oksijeni ephezulu. Le nkqubo ibandakanya ukusetyenziswa kwesefa ekhethekileyo yemolekyuli ekhetha ngokukhetha ukungcola okufana nenitrogen, ikharbon diokside, namanzi aphuma emoyeni kuxinzelelo lweatmospheric. Emva koko i-sieve ihlanjululwe phantsi kweemeko ze-vacuum, ikhupha ezi zinto zingcolileyo kwaye ivelise i-oksijeni ngezinga lokucoceka kwe-90-93%. Le nkqubo ye-cyclical iyasebenza kakhulu kwaye ihambelana nokusingqongileyo, iyenza ibe yinto ekhethwayo kumashishini afuna umthamo omkhulu we-oksijini ecocekileyo.

IIsityalo se-oxygen seVPSAisebenza ngoluhlu lwamacandelo antsonkothileyo, kubandakanywa isivuthelo, impompo yokufunxa, ivalve yokutshintsha, i-adsorption tower, kunye netanki yokulinganisa ioksijini. Inkqubo iqala ngokungena komoya okrwada, ohluzwayo ukususa amasuntswana othuli. Lo moya uhluziweyo ucinezelwa yi-Roots blower kuxinzelelo lwe-0.3-0.5 BARG kwaye uqondiswe kwenye yeenqaba ze-adsorption. Ngaphakathi kwinqaba, umoya udibana nezixhobo ze-adsorbent. Emazantsi enqaba, i-alumina esebenzayo idsorb amanzi, ikharbon diokside, kunye nezinye iigesi zomkhondo. Ngaphezulu kwalo maleko, iisefu zemolekyuli ze-zeolite zibhengeza initrogen, ivumela ioksijini kunye ne-argon ukuba idlule njengegesi yemveliso. Le gesi eneoksijini etyebileyo ke iqokelelwa kwitanki yokulinganisa ioksijini.

Njengoko inkqubo ye-adsorption iqhubeka, izinto ze-adsorbent ngokuthe ngcembe zifikelela kwi-saturation. Ngeli xesha, inkqubo itshintshela kwisigaba sokuvuselela. I-valve yokutshintsha iqondisa ukuhamba kwelinye icala, kwaye ipompo yokucoca iyancipha uxinzelelo kwinqaba ukuya kwi-0.65-0.75 BARG. Le meko yokucoca ikhupha ukungcola kwe-adsorbed, ethi ke ikhutshwe emoyeni, ihlaziye ngokufanelekileyo i-adsorbent kumjikelo olandelayo.

IIjenereyitha ye-oxygen yeVPSAyenzelwe ukusebenza ngokuqhubekayo, ukubonelela ngokuzinza kwe-oksijeni ephezulu. Ukusebenza kakuhle kunye nokuthembeka kwayo kuyenza ibe yinxalenye ebalulekileyo kumashishini ahlukeneyo, kubandakanywa ezonyango, ukuvelisa, kunye nesinyithi. Ukukwazi ukuvelisa i-oksijini kwi-site kunciphisa imiceli mngeni kunye neendleko ezinxulumene neendlela zendabuko zokubonelela nge-oksijini, ezifana nokuhanjiswa kwegesi yolwelo okanye ecinezelweyo.

Ngaphezu koko, itekhnoloji yeVPSA iyancipha, ivumela uhlengahlengiso ukuhlangabezana namanqanaba ahlukeneyo emfuno ye-oxygen. Oku kuguquguquka, kudibene neenzuzo zayo zokusingqongileyo kunye nokusebenza kakuhle kweendleko, kubeka iVPSAO₂indawo yokuvelisanjengesisombululo esikhokelayo sokuvelisa ioksijini kwindawo yale mihla yoshishino. Njengoko amashishini aqhubeka efuna iindlela zokuvelisa ezizinzileyo nezisebenzayo, isityalo se-oxygen ye-VPSA sibonakala njengeteknoloji yokucinga phambili ehlangabezana nale migaqo ngelixa iqinisekisa ukunikezelwa okuhambelanayo kwe-oksijeni ephezulu.
