Industrial oxygen jeneretatengerani zeolite molecular sieve ngati adsorbent ndikugwiritsa ntchito kuthamanga kwa adsorption, kuthamanga kwa desorption mfundo kuchokera ku air adsorption ndikutulutsa mpweya. Zeolite molecular sieve ndi mtundu wa spherical granular adsorbent yokhala ndi ma micropores pamwamba ndi mkati, ndipo ndi yoyera. Makhalidwe ake odutsa amathandizira kuti akwaniritse kulekanitsa kwa kinetic kwa O2 ndi N2. Kulekanitsa kwa zeolite molekyulu sieve pa O2 ndi N2 kutengera kusiyana pang'ono kwa kinetic diameter ya mipweya iwiriyi. Molekyu ya N2 imakhala ndi kufalikira kwachangu mu ma micropores a zeolite molekyulu sieve, pomwe molekyulu ya O2 imakhala ndi kufalikira pang'onopang'ono. Kufalikira kwa madzi ndi CO2 mu mpweya woponderezedwa sikusiyana kwambiri ndi nayitrogeni. Zomwe zimatuluka mu nsanja ya adsorption ndi mamolekyu a okosijeni. Pressure swing adsorptionkupanga mpweyandikugwiritsa ntchito mawonekedwe a zeolite molecular sieve kusankha adsorption, kugwiritsa ntchito kuthamanga kwa adsorption, desorption cycle, mpweya woponderezedwa mosinthana mu nsanja ya adsorption kuti mukwaniritse kulekanitsidwa kwa mpweya, kuti mupitirize kutulutsa mpweya.
1. Wopanikizika mpweya kuyeretsa unit
Mpweya wopanikizidwa woperekedwa ndi kompresa ya mpweya umadutsa kaye mu gawo loyeretsera mpweya, ndipo mpweya woponderezedwa umachotsedwa koyamba ndi sefa yamapaipi ambiri amafuta, madzi ndi fumbi, kenako amachotsedwanso ndi chowumitsira amaundana, fyuluta yabwino. pochotsa mafuta ndikuchotsa fumbi, ndipo fyuluta yabwino kwambiri imatsatiridwa ndikuyeretsa kwambiri. Malinga ndi momwe dongosolo limagwirira ntchito, TCWY idapanga mwapadera seti yoponderezedwa ya mpweya woponderezedwa kuti ateteze zotheka kulowa mafuta ndikupereka chitetezo chokwanira cha sieve yama cell. Zopangidwa mwaluso zida zoyeretsera mpweya zimatsimikizira moyo wautumiki wa sieve ya maselo. Mpweya wabwino wopangidwa ndi gululi ukhoza kugwiritsidwa ntchito ngati mpweya wa zida.
2. Tanki yosungiramo mpweya
Udindo wa thanki yosungiramo mpweya ndi: kuchepetsa kuthamanga kwa mpweya, kuchitapo kanthu; Choncho, kuthamanga kusinthasintha kwa dongosolo yafupika, kotero kuti wothinikizidwa mpweya akudutsa wothinikizidwa mpweya kuyeretsedwa chigawo chimodzi bwino, kuti mokwanira kuchotsa mafuta ndi madzi zosafunika, ndi kuchepetsa katundu wotsatira PSA mpweya ndi nayitrogeni kulekana chipangizo. Pa nthawi yomweyi, pamene nsanja ya adsorption imasinthidwa, imaperekanso mpweya wambiri woponderezedwa kwa PSA mpweya ndi nayitrogeni kulekana chipangizo kuti mofulumira kuonjezera kuthamanga mu nthawi yochepa, kotero kuti kuthamanga mu nsanja adsorption mwamsanga limatuluka. kupanikizika kwa ntchito, kuonetsetsa kuti zida zodalirika ndi zokhazikika.
3. Chipangizo cholekanitsa mpweya ndi nayitrogeni
Nsanja ya adsorption yokhala ndi sieve yapadera ya maselo imakhala ndi ziwiri, A ndi B. Pamene mpweya woyera wothinikizidwa umalowa kumapeto kwa nsanja A ndikudutsa mu sefa ya maselo mpaka kumapeto, N2 imadsorbed ndi iyo, ndipo mpweya wa okosijeni umatuluka. kuchokera kumapeto kwa nsanja ya adsorption. Patapita nthawi, sieve ya molekyulu mu Tower A inadzazidwa ndi adsorption. Panthawiyi, nsanja A imangoyimitsa kukopa, mpweya woponderezedwa umalowa mu Tower B kuti mutenge nayitrogeni ndi kupanga mpweya, ndipo sieve ya molekyulu ya Tower A imapangidwanso. Kusinthika kwa sieve ya maselo kumatheka ndikugwetsa mwachangu nsanja ya adsorption ku kuthamanga kwa mumlengalenga kuchotsa adsorbed N2. Zinsanja ziwirizi zimasinthidwa mosinthana ndikusinthidwanso kuti amalize kulekanitsa mpweya ndi nayitrogeni komanso kutuluka kosalekeza kwa mpweya. Njira zomwe zili pamwambazi zimayendetsedwa ndi programmable logic controller (PLC). Pamene kuyeretsedwa kwa okosijeni kumapeto kwa chotulukako kukhazikitsidwa, pulogalamu ya PLC imagwira ntchito, valavu yotsegulira yokha imatsegulidwa, ndipo mpweya wosayenerera umatulutsidwa kuti zitsimikizire kuti mpweya wosayenerera suyenda kumalo a mpweya. Gasi akamatuluka, phokoso limakhala lochepera 75dBA pogwiritsa ntchito silencer.
4. thanki ya okosijeni
Tanki ya okosijeni imagwiritsidwa ntchito polinganiza kupanikizika ndi kuyera kwa mpweya wolekanitsidwa ndi njira yolekanitsa mpweya wa nayitrogeni kuti zitsimikizire kukhazikika kwa mpweya wopitilirabe. Pa nthawi yomweyo, pambuyo ntchito adsorption nsanja anazimitsa, izo adzadzaza gawo la mpweya wake kubwerera ku nsanja adsorption, pa dzanja limodzi kuthandiza adsorption nsanja kuthamanga, komanso kuchita mbali kuteteza bedi, ndikugwira ntchito yofunika kwambiri yothandizira njira pakugwirira ntchito kwa zida.
