Kungani kuthatha isikhathi ukuqala nokumisa ijeneretha ye-nitrogen ye-PSA? Kunezizathu ezimbili: eyodwa ihlobene ne-physics kanti enye ihlobene nomsebenzi wezandla.

1.Ukulingana kwe-Adsorption kudinga ukusungulwa.

I-PSA inothisa i-N₂ ngokukhangisa i-O₂/ umswakama kusisefo samangqamuzana. Uma isanda kuqaliswa, isisefo se-molecular kufanele sifinyelele kancane kancane kumjikelezo we-adsorption/desorption ozinzile ukusuka endaweni engagcwele noma engcoliswe isimo somoya/umswakama ukuze kukhishwe ubumsulwa obuqondiwe phakathi nomjikelezo ozinzile. Le nqubo yokufinyelela esimweni esingaguquki idinga imijikelezo eminingana ephelele ye-adsorption/desorption (imvamisa esukela emashumini amasekhondi ukuya kumaminithi ambalwa/amashumi emizuzu, kuye ngevolumu yombhede kanye nemingcele yenqubo).

2.Ingcindezi kanye nezinga lokugeleza kwesendlalelo sombhede kuzinzile.

Ukusebenza kahle kwe-adsorption kwe-PSA kuncike kakhulu kumfutho wokusebenza kanye nesivinini segesi. Lapho uqala, i-compressor yomoya, isistimu yokomisa, ama-valve namasekhethi egesi adinga isikhathi sokucindezela isistimu kungcindezi eklanyelwe futhi azinzise izinga lokugeleza (okuhlanganisa ukubambezeleka kwesenzo se-stabilizer yokucindezela, isilawuli se-stabilizer kanye ne-valve yokuqala ethambile).

3.Ukutholwa kwemishini yokwelapha ngaphambi kwesikhathi

Ukuhlunga komoya kanye nezomisi eziqandisiwe/ama-desiccants kufanele kuqala kuhlangabezane nezindinganiso (izinga lokushisa, iphuzu lamazolo, okuqukethwe kwamafutha); uma kungenjalo, izisefo zamangqamuzana zingangcoliswa noma zibangele ukushintshashintsha kokuhlanzeka. Isomisi esiqandisiwe kanye nesihlukanisi samanzi samafutha nazo zinesikhathi sokubuyisela.

4.Ukubambezeleka kwenqubo yokukhipha kanye nokuhlanza

Ngesikhathi somjikelezo we-PSA, kukhona ukushintshwa, ukukhipha kanye nokuvuselelwa. Ukushintshwa kokuqala nokuvuselela kufanele kuqedwe ekuqaleni ukuze kuqinisekiswe ukuthi ungqimba lombhede “luhlanzekile”. Ngaphezu kwalokho, abahlaziyi bokuhlanzeka (abahlaziyi be-oksijeni, abahlaziyi be-nitrogen) banokubambezeleka kwempendulo, futhi uhlelo lokulawula ngokuvamile ludinga ukufaneleka okuqhubekayo kwamaphuzu amaningi ngaphambi kokukhipha isignali "yegesi efanelekayo".

 5.Ukulandelana kwama-valve kanye ne-logic yokulawula

Ukuze uvimbele ukulimala kwe-sieve yamangqamuzana noma ukukhiqizwa kwegesi ephezulu yokugxila ngokushesha, uhlelo lokulawula lwamukela ukushintshwa kwesinyathelo ngesinyathelo (ukuvula / ukuvala isigaba ngesigaba), okuyinto ngokwayo eyethula ukubambezeleka ukuze kuqinisekiswe ukuthi isinyathelo ngasinye sifinyelela ukuzinza ngaphambi kokudlulela kwesinye.

6.Inqubomgomo Yezokuphepha Nokuvikela

Abakhiqizi abaningi bahlanganisa amasu anjengesikhathi esincane sokusebenza kanye nokubambezeleka kokuvikela (ukubuyisela emuva ukuvuthela/ukunciphisa ingcindezi) ku-software yabo kanye nehadiwe ukuze bavimbele ukuqala nokuyeka ukulimaza amathuluzi nama-adsorbent.

Sengiphetha, isikhathi sokuqalisa asisona isici esisodwa kodwa sibangelwa ukunqwabelana kwezingxenye ezimbalwa, okuhlanganisa ukwelashwa kwangaphambili + ukusungulwa kwengcindezi + ukuqina kombhede we-adsorption + ukulawula/ukuhlaziya ukuqinisekiswa.
