Ukusasazwa kobushushu bangaphakathi be-plate fin heat exchanger kwinkqubo yolwelo

Ukusasazwa kobushushu bangaphakathi be-plate fin heat exchanger kwinkqubo yolwelo:
1） Umjikelo wokwandiswa kweNitrogen: umahluko wobushushu botshintshiselwano lobushushu kwiziphelo ezimbini nakwindawo ephakathi yesitshintshiselwano sobushushu mncinci kakhulu, kwaye umahluko wobushushu botshintshiselwano lobushushu kwezinye iindawo mkhulu kakhulu. Nangona kunjalo, kukho iimfuno ezithile zomahluko omncinci wobushushu botshintshiselwano lobushushu kuyilo lwesitshintshiselwano sobushushu, esingenakuba mncinci kakhulu. Ngokubanzi, ukusasazwa komahluko wobushushu botshintshiselwano lobushushu akulunganga, umahluko wobushushu mkhulu, kwaye ilahleko engenakuguqulwa inkulu, ngoko ke imfuno yamandla eshaft yecompressor ehambelana nayo iya kuba nkulu;
2） Umjikelo wokwandiswa kwe-nitrogen methane: amandla okupholisa kwindawo eshushu ephantsi ye-heat exchanger anikezelwa yi-throttle valve. Umxube we-nitrogen kunye ne-methane throttles kwaye uyaphola. Ngenxa yomxholo ophezulu we-methane, umahluko wobushushu ekupheleni kokubanda emva kokubhoboza umncinci. Emva kokuba ubushushu bunyukile, i-methane kunye ne-nitrogen ziyabila ngokukhawuleza, zibonelela ngomthamo omkhulu wokupholisa, nto leyo ebangela umahluko omkhulu wobushushu kwi-heat exchanger kwaye igesi exutyiweyo evuthuzayo iyaqhubeka nokunyuka. Ubushushu obuqondayo busetyenziselwa ukubonelela ngomthamo wokupholisa kwigesi yendalo yolwelo olunoxinzelelo oluphezulu, kwaye umahluko wobushushu uqala ukusebenza. Emva kokuba uncitshisiwe ukuya kwixabiso elithile, ulwelo olubandayo luxutywa negesi eshushu ephantsi kwindawo yokukhupha i-expander ukuze kuqhubeke ukubonelela ngomthamo wokupholisa kwinkqubo. Umahluko omncinci wobushushu ngaphakathi kwebhokisi ebandayo ukwisiphelo esishushu kakhulu, isiphelo esibandayo kunye nokudibana kolwelo olubhobozekileyo kunye nolwelo lokwandisa, Ngaphezu koko, umahluko ophakathi wobushushu be-heat exchanger nawo ungaphantsi kunowomjikelo wolwelo lokwandisa i-nitrogen;
3） MRC: umahluko wobushushu botshintshiselwano lobushushu kwisiphelo sobushushu esiphantsi ngaphakathi kwe-heat exchanger mncinci, kwaye umahluko wobushushu mkhulu xa usondele kubushushu obuqhelekileyo. Oku kungenxa yokuba i-isopentane isetyenziselwa ukuthatha indawo ye-butane kwi-refrigerant. Emva kokuba i-compressed mixed refrigerant ipholiswe ngamanzi olwandle, i-isopentane kwi-refrigerant ifakwa kulwelo. Kwi-throttled mixed refrigerant, i-isopentane iqala ukufuma kubushushu obuphezulu, ngobushushu obukhulu obufihlakeleyo bokufuma. Le nxalenye yomthamo wokupholisa ayinakusetyenziswa xa igesi yendalo kunye ne-high-pressure mixed refrigerant kwi-heat flow zipholile, ngoko ke, umahluko wobushushu botshintshiselwano lobushushu kweli candelo mkhulu. Nangona kunjalo, ukusebenzisa i-isopentane endaweni ye-butane njenge-high boiling point refrigerant akunakunciphisa ukusetyenziswa kwamandla kuphela, kodwa kwanokwandisa umahluko wobushushu botshintshiselwano lobushushu, nto leyo eluncedo kakhulu kwinkqubo yonke;
Njengoko inani lezigaba zomjikelo wokukhenkceza lisanda, ukusetyenziswa kwamandla kwenkqubo yokukhenkceza kuyancipha, kwaye i-coefficient yokukhenkceza kunye nokusebenza kakuhle kokuzivocavoca kuyakhula, kodwa impembelelo yokwanda kwenani lezigaba ekusebenzeni kokukhenkceza iyancipha. Ukwanda kwezigaba zomjikelo wokukhenkceza kuya kwandisa ubunzima benkqubo kwaye kunciphise ukusebenza. Amanqanaba afanelekileyo eenkqubo zokukhenkceza ezinezikali ezahlukeneyo ahlukile. Okukhona isikali sikhulu, kokukhona amanqanaba afanelekileyo;

I-MRC ibandakanya umjikelo onokuphola kwangaphambili kunye nomjikelo ngaphandle kokupholisa kwangaphambili. Umjikelo wokuphola kwangaphambili uquka ukupholisa okumsulwa kwefriji kunye nokupholisa okuxutyiweyo kwefriji. Iifriji ezixutyiweyo kwezi zigaba zahlulwe ngokwamanqanaba ahlukeneyo. Ulwelo olwahlulwe kwinqanaba ngalinye luyaphola kwaye lufakwe i-throttle ukuze lufrijiwe, kwaye igesi ehlukanisiweyo iyaqhubeka nokuphola kwaye yahlulwe. Amanqanaba okwahlula ahlukile, ubunzima benkqubo buhlukile, kwaye ukusebenza kakuhle komjikelo wokuphola kwahlukile;
37, Kuyilo lwenkqubo ye-MRC, kuyimfuneko ukwenza ngcono ulwakhiwo lwenkqubo kwaye ukhethe inombolo yomjikelo efanelekileyo. I-MRC ibandakanya i-MRC yesigaba esinye, i-MRC yesigaba esibini, i-MRC yesigaba esithathu kunye ne-MRC yesigaba esininzi. Le mijikelo yokukhenkceza isetyenziswa ngoku. Izigaba ezahlukeneyo zomjikelo wokukhenkceza, ukusetyenziswa kwamandla okukhenkceza ahlukeneyo kunye nobunzima obahlukeneyo benkqubo kufuneka zikhethwe ngokwezinga ezahlukeneyo zokucubungula. Ukulungiswa kwe-MRC kubandakanya ukwenziwa ngcono kwesakhiwo kunye nokulungiswa kweeparamitha zenkqubo;
