Kugoverwa kwekupisa kwemukati kweplate fin heat exchanger mu liquefaction system

Kugoverwa kwekupisa kwemukati kweplate fin heat exchanger mu liquefaction system:
1） Kutenderera kwekuwedzera kweNitrogen: musiyano wekupisa kuchinjana kwemhepo pamativi maviri nepakati pemuchina wekupisa mudiki kwazvo, uye musiyano wekupisa kuchinjana kwemhepo pane zvimwe zvikamu wakakura. Zvisinei, kune zvimwe zvinodiwa kuti pave nemusiyano mudiki wekupisa kuchinjana kwemhepo mukugadzirwa kwemuchina wekupisa, uyo usingakwanise kuva mudiki zvakanyanya. Kazhinji, kugoverwa kwemusiyano wekupisa kuchinjana kwemhepo musanganiswa hakuna kuenzana, musiyano wekupisa wakakura, uye kurasikirwa kusingadzoreki kwakakura, saka simba remubato wecompressor rinoenderana richave rakakura;
2） Kutenderera kwekuwedzera kweNitrogen methane: kugona kutonhora muchikamu chekupisa chakaderera chinopihwa nevharuvhu yethrottle. Musanganiswa wenitrogen nemethane unodzikisa uye unotonhorera. Nekuda kwehuwandu hwakawanda hwemethane, musiyano wekupisa pamucheto wechando mushure mekukanda unenge mudiki. Mushure mekunge tembiricha yakwira, methane nenitrogen zvinopera nekukurumidza, zvichipa huwandu hwakawanda hwekutonhodza, zvichikonzera musiyano mukuru wekupisa muheat exchanger uye gasi rakasanganiswa rinopfungaira rinoramba richikwira. Kupisa kunoshandiswa kupa kugona kutonhodza kwegasi rechisikigo rine pressure yakawanda, uye musiyano wekupisa unotanga kushanda. Mushure mekunge yaderedzwa kusvika kune imwe kukosha, mvura inotonhora inosanganiswa negasi rekupisa rakaderera paexpander outlet kuti irambe ichipa kugona kutonhodza kwesystem. Musiyano mudiki wekupisa mukati mebhokisi rinotonhora uri pamucheto unopisa, mugumo unotonhora zvakanyanya uye kusangana kwemvura yakapfungaira uye mvura yakapfungaira, Uyezve, musiyano wepakati wekupisa weheat exchanger zvakare wakaderera pane we nitrogen expansion liquefaction cycle;
3） MRC: musiyano wekupisa pakupera kwekupisa kwakaderera mukati meheat exchanger mudiki, uye musiyano wekupisa wakakura kana uri pedyo nekupisa kwakajairika. Izvi zvinonyanya kuitika nekuti isopentane inoshandiswa kutsiva butane mufiriji. Mushure mekunge firiji yakamanikidzwa yatonhodzwa nemvura yegungwa, isopentane mufiriji inosanganiswa kuita mvura. Mufiriji yakasanganiswa yakakandwa, isopentane inotanga kupwanyika pakupisa kwakakwira, nekupisa kukuru kwekupisa. Chikamu ichi chekukwanisa kutonhora hachigone kudyiwa kana gasi rechisikigo nefiriji yakasanganiswa yakamanikidzwa zvakanyanya mukupisa zvatonhodzwa, Saka, musiyano wekupisa pakupisa muchikamu chino wakakura. Zvisinei, kushandisa isopentane panzvimbo pebutane sefiriji yepamusoro hakungoderedzi kushandiswa kwesimba chete, asiwo kunowedzera musiyano wekupisa pakupisa, izvo zvinobatsira zvikuru kune system yese;
Nekuwedzera kwehuwandu hwematanho ekutenderera kwekutonhodza, kushandiswa kwesimba kwesystem yekutonhodza kunoderera, uye coefficient yekutonhodza uye kushanda nesimba kunowedzera, asi simba rekuwedzera kwehuwandu hwematanho pakushanda kwekutonhodza rinoderera. Kuwedzera kwematanho ekutenderera kwekutonhodza kuchawedzera kuoma kwemaitiro uye kuderedza kushanda. Matanho akanakisa esystem yekutonhodza ane zviyero zvakasiyana akasiyana. Kana chiyero chakakura, matanho akanakisa anowanda;

MRC inosanganisira cycle ine precooling uye cycle isina precooling. Precooling cycle inosanganisirawo pure refrigerant precooling uye mixed refrigerant precooling. Ma mixed refrigerants mu cycle idzi akakamurwa kuita nhanho dzakasiyana. Mvura yakaparadzaniswa kubva padanho rega rega inotonhodzwa uye inokandwa kuti itonhore, uye gasi rakaparadzaniswa rinoramba richitonhodzwa uye richiparadzaniswa. Matanho ekuparadzanisa akasiyana, kuoma kwemaitiro acho kwakasiyana, uye kushanda zvakanaka kwe friji cycle kwakasiyana;
37, Mukugadzira maitiro eMRC, zvakakosha kugadzirisa chimiro chemaitiro uye kusarudza nhamba yakakodzera yedenderedzwa. MRC inosanganisira MRC ine nhanho imwe chete, MRC ine nhanho mbiri, MRC ine nhanho nhatu uye MRC ine nhanho dzakawanda. Aya madenderedzwa edenderedzwa ari kushandiswa parizvino. Matanho akasiyana ekutenderera kwedenderedzwa, kushandiswa kwesimba remufiriji kwakasiyana uye kuoma kwakasiyana kwemaitiro kunofanirwa kusarudzwa zvichienderana nehukuru hwakasiyana hwekugadzirisa. Kugadzirisa MRC kunosanganisira kugadzirisa chimiro uye kugadzirisa maparamendi emaitiro;
