Isitshalo se-Cryogenic oxygen sibiza isitshalo se-oxygen esiwuketshezi
Izinzuzo Zomkhiqizo
- 1:Umgomo wokuklama walesi sitshalo ukuqinisekisa ukuphepha, ukonga amandla kanye nokusebenza okulula nokunakekelwa. Ubuchwepheshe buhamba phambili emhlabeni.
-
- IMP: Umthengi udinga uketshezi oluningi olukhiqizwayo, ngakho-ke sinikezela ngenqubo yokuvuselela umoya ophakathi nendawo ukuze konge ukutshalwa kwezimali kanye nokusetshenziswa kwamandla.
- B: Samukela i-recycle air compressor kanye nesilingo esiphakeme, esiphansi. inqubo yokwandisa ukonga ukusetshenziswa kwamandla.
- I-2: Yamukela ubuchwepheshe bokulawula ikhompyutha ye-DCS ukulawula iphaneli eyinhloko, iphaneli yendawo ngesikhathi esifanayo. Lolu hlelo lungakwazi ukuqapha yonke inqubo yesitshalo.
Izinkambu Zokusebenza
I-oksijeni, i-nitrogen, i-argon kanye nenye igesi engavamile ekhiqizwa iyunithi yokuhlukanisa umoya isetshenziswa kabanzi ensimbi, kumakhemikhali.
imboni, indawo yokucwenga, ingilazi, irabha, i-electronics, ukunakekelwa kwezempilo, ukudla, izinsimbi, ukukhiqiza ugesi nezinye izimboni.
Ukucaciswa komkhiqizo
Isitshalo sokuhlukanisa umoya sisekelwe kumaphuzu ahlukene abilayo ezingxenyeni ngayinye ezisemoyeni. Umoya uqala ngokucindezelwa, upholile, bese ukhishwa i-H2O ne-CO2. Ngemva kokupholisa kumshini wokushisa ophakathi nendawo kuze kufinyelele izinga lokushisa loketshezi oluncibilikayo, ilungisa kukholomu ukuze ithole umoya-mpilo owuketshezi kanye ne-nitrogen ewuketshezi.
Lesi sitshalo sihlanza umoya we-molecular sieve ngenqubo ye-turbo expander.
Ngemva kokukhishwa uthuli nokungcola kwemishini kusihlungi somoya, umoya ongahluziwe uya ku-compressor ye-turbine yomoya ukuze ucindezele umoya uye ku-1.1MpaA, futhi upholiswe kuze kube ngu-10℃ kuyunithi yokupholisa kuqala komoya. Bese ingena kwesinye i-molecular sieve absorber esebenzayo ukuze isuse i-H2O, CO2,C2H2. Umoya ohlanzekile ucindezelwa yi-expander bese ungena ebhokisini elibandayo. Umoya wokucindezela ungahlukaniswa ube izingxenye ezi-2. Ngemva kokupholiswa ku-256K, ingxenye eyodwa idonselwa kuyunithi eqandayo engu-243K, bese ipholiswa ngokuqhubekayo kusishintshisi sokushisa esikhulu. Umoya opholile uzodonselwa ku-expander, futhi ingxenye yomoya owandisiwe ingena emshinini wokushisa oyinhloko ukuze ushise kabusha, bese uyaphuma ebhokisini elibandayo. Futhi ezinye izingxenye ziya kukholamu engenhla. Esinye isigaba sipholiswa ngokugeleza kwekhawunta, futhi siya kukholomu ephansi ngemva kokunwetshwa.
Ngemva kokuba umoya usulungisiwe ngokuyinhloko, singathola umoya owuketshezi, simoshe i-nitrogen ewuketshezi kanye ne-nitrogen ewuketshezi emsulwa kukholamu ephansi. Umoya owuketshezi, i-nitrogen ewuketshezi oluwuketshezi kanye ne-nitrogen ewuketshezi emuncwa ohlwini oluphansi iya kukholomu engenhla ngemva kokupholisa uketshezi olupholile kanye nesipholile se-nitrogen esiwuketshezi. Ngemva kokulungiswa kukholamu engenhla, singathola u-99.6% we-oksijini yoketshezi ehlanzekile ngaphansi kwekholomu engenhla, uphuma njengomkhiqizo. Ingxenye ye-nitrogen emuncwa phezulu kwekholomu yokusiza iphuma ebhokisini elibandayo njengomkhiqizo.
I-nitrogen eyimfucumfucu emuncwa phezulu kwekholomu engenhla iphuma ebhokisini elibandayo ngemva kokushisisa kabusha i-cooler kanye nesishintshi sokushisa esikhulu. Imunce ingxenye yayo, iya ohlelweni lokuhlanzwa kwe-molecular sieve njengomthombo womoya ovuselelayo. Ezinye zikhishwa umoya.
