Kumvetsetsa PSA ndi VPSA Njira Zopangira Oxygen

Kupanga okosijeni ndizovuta kwambiri m'mafakitale osiyanasiyana, kuchokera ku zamankhwala kupita ku mafakitale. Njira ziwiri zodziwika bwino zomwe zimagwiritsidwa ntchito pazolinga izi ndi PSA (Pressure Swing Adsorption) ndi VPSA (Vacuum Pressure Swing Adsorption). Njira zonsezi zimagwiritsa ntchito masieve a mamolekyu kuti alekanitse mpweya ndi mpweya, koma amasiyana m'machitidwe awo ndi momwe amagwiritsira ntchito.

PSA Oxygen Production

PSA mpweya jeneretaKuphatikizira kugwiritsa ntchito sieve ya mamolekyulu kuti azitha kutengera nayitrogeni kuchokera ku mpweya wopanikizika kwambiri ndikuumasula pansi pa kupsinjika kochepa. Izi zimachitika mozungulira, zomwe zimalola kuti mpweya wa okosijeni ukhale wopitilira. Dongosololi limaphatikizapo makina opangira mpweya kuti apereke mpweya wofunikira kwambiri, bedi la molecular sieve, ndi dongosolo lowongolera kuti azitha kuwongolera kuzungulira ndi kusokoneza.
Zigawo zazikulu za dongosolo la PSA ndi monga chopondera mpweya, bedi la molecular sieve, ndi dongosolo lowongolera. Mpweya wa compressor umapereka mpweya wothamanga kwambiri, womwe umadutsa pabedi la sieve ya maselo. Sieve ya molekyulu imadsorbetsa nayitrogeni, kusiya okosijeni kuti asonkhanitsidwe. Pambuyo pofika kukhuta, kupanikizika kumachepetsedwa, kulola kuti nayitrogeni itulutsidwe ndipo sieve ibwezeretsedwenso pamzere wotsatira.

VPSA Oxygen Production

VPSA, kumbali ina, imagwira ntchito pansi pa vacuum kuti ipititse patsogolo luso la masieve a molecular adsorption and desorption process. Njirayi imagwiritsa ntchito ma sieve a ma molekyulu ndi mapampu a vacuum kuti akwaniritse mpweya wabwino kwambiri. The VPSA mpweya zomera zikuphatikizapo vacuum mpope, molecular sieve bedi, ndi dongosolo ulamuliro.
The VPSA ndondomeko akuyamba ndi mpweya kukokedwa mu dongosolo pansi zingalowe mikhalidwe. Sieve ya molekyulu imadsorbetsa nayitrogeni ndi zonyansa zina, ndikusiya mpweya. Sieve ikakhutitsidwa, chopukutira chimagwiritsidwa ntchito kutulutsa mpweya wa adsorbed, ndikubwezeretsanso sieve kuti igwiritsidwe ntchito.

Kufananiza ndi Kugwiritsa Ntchito

Onse PSA ndi VPSA ndi ogwira popanga mkulu-kuyera mpweya, koma amasiyana zofuna zawo ntchito ndi lonse. Makina a PSA nthawi zambiri amakhala ang'onoang'ono komanso osunthika, kuwapangitsa kukhala oyenera kugwiritsa ntchito pomwe malo ali ochepa, monga zipatala kapena mafakitale ang'onoang'ono. Machitidwe a VPSA, ngakhale akuluakulu komanso ovuta, amatha kupanga mpweya wambiri wa okosijeni ndipo nthawi zambiri amagwiritsidwa ntchito m'mafakitale akuluakulu.
Pankhani yogwira ntchito bwino, machitidwe a VPSA nthawi zambiri amakhala osagwiritsa ntchito mphamvu zambiri chifukwa cha malo opanda mpweya, omwe amachepetsa mphamvu zomwe zimafunikira kuti ziwonongeke. Komabe, ndalama zoyendetsera ntchito za VPSA ndizokwera kwambiri poyerekeza ndi machitidwe a PSA.

Mapeto

PSA ndi VPSA mafakitale mpweya jenereta kupereka njira odalirika ndi kothandiza kwa mpweya m'badwo, aliyense ndi ubwino wake wapadera ndi ntchito. Kusankha pakati pa ziwirizi nthawi zambiri kumadalira zofunikira zomwe zimagwiritsidwa ntchito, kuphatikizapo kuchuluka kwa mpweya wofunikira, mlingo wachiyero wofunikira, ndi malo omwe alipo ndi bajeti. Njira zonsezi zimathandiza kwambiri kuti pakhale zofunikira zosiyanasiyana za mafakitale ndi zipatala, kuonetsetsa kuti mpweya umakhala wokhazikika kumene ukufunikira kwambiri.
