Incazelo Yomkhiqizo
Umshini we-nitrogen oketshezi oxubekile we-liquid usekelwe kumjikelezo wefriji wokuphinda uvuseleleke. Kusukela ekushiseni kokushisa ukukhomba ukushisa kwefriji, izingxenye ezibandayo eziphakeme, eziphakathi nendawo kanye neziphansi zibunjwe ngamafriji amaningi ahlanganisiwe, ukuze izindawo zokushisa ezipholile ezisebenzayo zihlangane. Ngale ndlela, ukufaniswa kokusabalalisa indawo yokushisa okupholile kuphelelisiwe, futhi ukufaniswa okuphumelelayo kokushisa kwendawo yokushisa yendawo ngayinye ebilayo kuyabonakala, ngaleyo ndlela kuqaphele ukusebenza kwefriji okusebenza kahle nge-span enkulu yokushisa, kanye nomphumela wefriji ophakeme kakhulu ongatholwa ngaphansi komehluko omncane wokucindezela. Ngakho-ke, i-compressor efriji esiteji esisodwa esivuthiwe enkambeni ebandayo ejwayelekile ingasetshenziselwa ukushayela ifriji elixubekile elixubene nesiqandisi sokufeza ifriji esezingeni eliphansi.
Ubuchwepheshe obubizwa ngenhla obuhlanganisiwe bokuqandisa amafriji busetshenzisiwe kuzinhlelo eziningi kanye nemikhakha yezimboni. Isibonelo, embonini yokuqothula igesi yemvelo, inqubo yokuxuba isiqandisi esihlanganisiwe ithatha isikhundla esikhulu. Okwezinga lokushisa lesicelo kanye nesikali esithintekayo kule phrojekthi, imishini evuthiwe efana ne-compressors kanye ne-heat exchange emkhakheni obandayo jikelele kungamukelwa ukuze kuthuthukiswe kakhulu ukuthembeka kohlelo, futhi imithombo yemishini ibanzi futhi izindleko ziphansi kakhulu.
Izici zesifriji esixubene nesiqandisi
1) Ukuqala okusheshayo nokuphakama kokupholisa okusheshayo. Ngokuxubana kwesilinganiso sokuhlushwa esiqandisini, ukulungiswa kwesibali se-compressor nokulawula ukuvulwa kwe-valve mpintsha, izidingo zokupholisa ngokushesha zingatholakala;
2) Inqubo ilula, inani lemishini lincane, futhi ukuthembeka kohlelo kuphezulu. Izingxenye eziyinhloko zohlelo zisebenzisa ama-compressors avuthiwe, ama-heat exchangers neminye imishini ensimini yefriji. Uhlelo lunokwethenjelwa okuphezulu kanye nemithombo ehlukahlukene yemishini.
Izinkomba zobuchwepheshe nezidingo zokusetshenziswa
Izinga lokushisa elifanele: kufika ku-45 ℃ (ehlobo)
Ukuphakama: amamitha ayi-180
Okukhipha i-nitrogen oketshezi: 3L / h kuye ku-150L / h
Umkhiqizi we-PSA nitrogen usebenzisa umoya njengezinto ezingavuthiwe, ikhwalithi ephezulu yekhabhoni yesisefo njenge-adsorbent, isebenzisa umgomo wokucindezela ukukhishwa kwe-adsorption, isebenzisa i-sieve yamangqamuzana egcwele ama-micropores ukukhetha ngokukhangisa umoya ukufeza injongo yokwehlukaniswa kwe-oxygen ne-nitrogen, futhi khiqiza ubumsulwa obuphezulu i-Nitrogen ikakhulukazi ifaka imishini efana ne-air compressors, izihlungi, amathangi wokuqhuma, ama-dryer omisa, imibhoshongo ye-adsorption, namathangi wokugcina i-nitrogen amsulwa.
Ama-MRC liquefaction units ikakhulukazi afaka amayunithi we-compressor wangaphambi kokupholisa, ama-coolers wangaphambi kokupholisa, amayunithi we-compressor aphambili, amayunithi we-compressor aphambili, ama-coolers aphezulu okupholisa umoya, amabhokisi abandayo, amathangi we-nitrogen wamanzi, amasistimu wokutakula we-BOG nezinhlelo zokulawula. I-main / pre-cooling compressor unit ifaka i-compressor eyinhloko / ebandayo ne-separator yamafutha e-lubricating, i-lubricating oil precision filter, i-activated carbon adsorber, i-lubricating oil circulating pump kanye ne-tank yokugcina isitoreji esihlanganisiwe, njll. ukusebenzisa umgomo wokuxuba oketshezi olusebenzayo lokuvuselela uketshezi ukuhlinzeka ngefriji yokuqothulwa kwenitrogen. Izinga lokushisa eliphansi leyunithi lingafinyelela ku -180 ° C.
