Kodi Chomera cha Oxygen cha VPSA Chimagwira Ntchito Motani?

A VPSA, kapena Vacuum Pressure Swing Adsorption, ndi luso lamakono lomwe limagwiritsidwa ntchito popanga mpweya wabwino kwambiri. Kuchita zimenezi kumaphatikizapo kugwiritsa ntchito sefa yapadera ya mamolekyu omwe amatchinjiriza zonyansa monga nayitrogeni, mpweya woipa, ndi madzi ochokera mumpweya pamphamvu ya mumlengalenga. Sieveyo imaphwanyidwa pansi pazimenezi, ndikutulutsa zonyansazi ndikupanga mpweya wokhala ndi chiyero cha 90-93%. Njira yozungulira iyi ndiyothandiza kwambiri komanso yogwirizana ndi chilengedwe, ndikupangitsa kuti ikhale chisankho chokondedwa m'mafakitale omwe amafunikira mpweya wambiri wa oxygen.

TheChomera cha okosijeni cha VPSAimagwira ntchito kudzera m'magulu angapo apamwamba kwambiri, kuphatikiza chowombera, chopopera chopukutira, valavu yosinthira, nsanja ya adsorption, ndi tanki yoyendera mpweya. Njirayi imayamba ndi kulowetsa mpweya wosaphika, womwe umasefedwa kuchotsa tinthu ta fumbi. Mpweya wosefedwawu umakanikizidwa ndi Roots blower mpaka kukanikiza kwa 0.3-0.5 BARG ndikulunjikitsidwa mu imodzi mwa nsanja zotsatsira. Mkati mwa nsanjayo, mpweya umakumana ndi zida za adsorbent. Pansi pa nsanjayo, aluminiyamu yoyendetsedwa imatulutsa madzi, mpweya woipa, ndi mpweya wina wotsatira. Pamwamba pa wosanjikiza uwu, ma sieve a molekyulu a zeolite amadsorb nayitrogeni, kulola mpweya ndi argon kudutsa ngati mpweya wamafuta. Mpweya wochuluka wa okosijeni umenewu umasonkhanitsidwa mu thanki ya oxygen.

Pamene njira ya adsorption ikupitirira, zipangizo za adsorbent pang'onopang'ono zimafika pa machulukitsidwe. Panthawiyi, dongosololi limasinthira ku gawo lokonzanso. Valavu yosinthira imawongolera kuthamangira kwina, ndipo pampu ya vacuum imachepetsa kuthamanga kwa nsanjayo ku 0.65-0.75 BARG. Izi vacuum chikhalidwe kumasula zonyansa adsorbed, amene kenako kutayidwa mu mlengalenga, bwino regenerating adsorbent kwa mkombero wotsatira.

TheVPSA mpweya jeneretalapangidwa kuti lizigwira ntchito mosalekeza, kupereka mpweya wokhazikika wa okosijeni woyeretsedwa kwambiri. Kuchita bwino kwake komanso kudalirika kumapangitsa kuti ikhale yofunika kwambiri m'mafakitale osiyanasiyana, kuphatikiza zamankhwala, kupanga, ndi zitsulo. Kutha kupanga okosijeni pamalowo kumachepetsa zovuta zogwirira ntchito komanso ndalama zomwe zimayenderana ndi njira zachikhalidwe zoperekera okosijeni, monga kuperekera mpweya wamadzimadzi kapena woponderezedwa.

Komanso, luso VPSA ndi scalable, kulola kuti zosintha kukumana osiyana mpweya kufunika milingo. Kusinthasintha uku, kuphatikizidwa ndi mapindu ake azachilengedwe komanso kutsika mtengo, kumayika VPSAO₂kupangamonga njira yotsogola yopangira mpweya wa okosijeni m'mafakitale amakono. Pamene mafakitale akupitiriza kufunafuna njira zopangira zokhazikika komanso zogwira mtima, chomera cha okosijeni cha VPSA chikuwoneka ngati luso lachidziwitso chamtsogolo lomwe limakwaniritsa izi ndikuwonetsetsa kuti mpweya wabwino umakhala wokhazikika.
