Zowunikira:
1, Chigawo cha ASU chokhala ndi okosijeni chochepa kwambiri chopangidwa ndi Shanghai LifenGas chakwanitsa maola opitilira 8,400 ogwira ntchito mokhazikika komanso mosalekeza kuyambira Julayi 2024.
2, Imasunga milingo yoyera ya okosijeni pakati pa 80% ndi 90% ndi kudalirika kwakukulu.
3, Imachepetsa kugwiritsa ntchito mphamvu zonse ndi 6% -8% poyerekeza ndi machitidwe azikhalidwe olekanitsa mpweya.
4, Makina okhazikika bwino amaonetsetsa kuti ntchitoyo ikugwira ntchito mosavuta ndipo imapereka mpweya wodalirika wa O2ndi N2ndi zofunika zosamalira zochepa.
5, Pulojekitiyi imathandizira makasitomala kupititsa patsogolo mphamvu, kuchepetsa mpweya, ndi kulimbikitsa chitukuko chokhazikika.
Cryogenic low-purity oxygen-enriched air separation unit (ASU) imagwiritsa ntchito ukadaulo wolekanitsa wocheperako kutentha kuti ichotse mpweya ndi nayitrogeni mumlengalenga kudzera munjira zopondereza, zoziziritsa, ndi distillation, zomwe ndizofunikira kwambiri pakuyaka kwa okosijeni. Machitidwewa amatha kutulutsa mpweya wabwino kwambiri wosinthika pakati pa 80% ndi 93%, pomwe nthawi yomweyo amatulutsa mpweya wabwino kwambiri (99.6%), nayitrogeni yoyera kwambiri (99.999%), mpweya wa zida, mpweya wothinikizidwa, mpweya wamadzimadzi, nayitrogeni wamadzimadzi, ndi zinthu zina. Amagwiritsidwa ntchito kwambiri posungunula zitsulo zopanda chitsulo, kubwezeretsa zitsulo zamtengo wapatali, kupanga magalasi, mafakitale amagetsi, ndi mafakitale.
Ubwino waukulu wa njira ya okosijeni ya cryogenic yotsika kwambiri imaphatikizapo kutulutsa kwazinthu zambiri, kutsika kwaphokoso-makamaka ma frequency otsika-komanso kusinthasintha kwa magwiridwe antchito kuyambira 75% mpaka 105%, kufalikira mpaka 25% -105% ndi masinthidwe apawiri a kompresa. Ndi mphamvu ya unit imodzi yofikira 100,000 Nm³/h, imapereka 30% yotsika mtengo yamtengo wapatali ndi 10% yocheperako kuposa machitidwe a VPSA a mphamvu zofanana, pamodzi ndi kuchepetsedwa kwa ndalama zogwirira ntchito ndi kukonza.
Chitsanzo chabwino cha ukadaulo wapamwambawu ndi ntchito ya ASU yopangidwa ndi Shanghai LifenGas ya Ruyuan Xinyuan Environmental Metal Technology Co., Ltd. Kuyambira pomwe idakhazikitsidwa mu Julayi 2024, makinawa akwanitsa maola opitilira 8,400 akugwira ntchito mosasunthika, akusunga nthawi zonse kuyeretsedwa kwa oxygen, kuyeretsa mpweya ndi 900%. 6% ~ 8% poyerekeza ndi machitidwe achikhalidwe olekanitsa mpweya-kukwaniritsadi ntchito yabwino komanso yotsika mpweya.
Pogwiritsa ntchito njira zapamwamba za cryogenic ndi luso lapamwamba lapamwamba la mkati, lophatikizidwa ndi machitidwe anzeru olamulira ndi zida zopulumutsira mphamvu, dongosololi limachepetsa kwambiri mphamvu yogwiritsira ntchito mphamvu pa unit ndikuwongolera kupanga gasi. Makina okhazikika, osavuta kugwiritsa ntchito, komanso ndi zofunikira zocheperako, amapereka makasitomala ndi mpweya wokhazikika komanso wodalirika.
Masiku ano, ASU iyi yakhala maziko ofunikira a Ruyuan Xinyuan, kupititsa patsogolo zokolola ndikuthandizira zolinga zochepetsera utsi. Imakhalanso ndi zinthu zamadzimadzi zodzipangira zokha zomwe zitha kugwiritsidwa ntchito m'makina osunga zobwezeretsera, kuthetsa kugula kwakunja ndikuwongolera kudalirika kwamagetsi.
Shanghai LifenGas ikupitiriza kupatsa mphamvu makasitomala amakampani ndi njira zothetsera gasi zokhazikika komanso zotsika mtengo. KDON-11300 yathu yayikulu yoyera ya oxygen ASU ya ng'anjo yosungunula yowomberedwa ndi okosijeni ya Guangxi Ruiyi ikugwiranso ntchito mokhazikika.

Xiaoming imayang'anira chitetezo cha projekiti ndi kasamalidwe ka ntchito zophatikizika. Pokhala ndi chidziwitso chochuluka mu machitidwe olekanitsa mpweya wa cryogenic, amazindikiritsa ndi kuthetsa zoopsa zomwe zingatheke, amathandizira kukonza zipangizo, ndikuonetsetsa kuti ntchito yokhazikika, yogwira ntchito, komanso yotsika kwambiri ya mpweya wa mpweya.
