Kugovera kwemukati tembiricha yeplate fin heat exchanger mu liquefaction system

Kugovera kwemukati tembiricha yeplate fin heat exchanger mune liquefaction system:
1) Nitrogen yekuwedzera kutenderera: mutsauko wekupisa wekupisa pamigumo miviri nepakati penzvimbo yekupisa idiki kwazvo, uye musiyano wekupisa wekupisa kune dzimwe nzvimbo wakakura. Nekudaro, pane zvimwe zvinodikanwa zvehushoma hwekupisa kupisa mutsauko mukugadzirwa kweanopisa kupisa, izvo zvisingagone kuve diki zvakanyanya. Kazhinji, kugoverwa kwekupisa kwekushisa kwekushisa kwakasiyana hakuna kuenzana, kusiyana kwekushisa kwakakura, uye kurasikirwa kusingadzoreki kwakakura, saka shaft simba rinodiwa recompressor rinoenderana richave rakakura;
2） Nitrogen methane yekuwedzera kutenderera: iyo inotonhorera inotonhorera mune yakaderera-tembiricha chikamu chekupisa chinopihwa neiyo throttle valve. Musanganisi wenitrogen uye methane anofenda uye anotonhorera pasi. Nekuda kweiyo methane yemukati, mutsauko wetembiricha pakupera kwechando mushure mekugwinha mudiki. Mushure mekunge tembiricha yakwira, methane nenitrogen zvinonyunguduka nekukurumidza, zvichipa huwandu hukuru hwekutonhodza, zvichikonzera musiyano mukuru wetembiricha mumoto wekupisa uye gasi rakasanganiswa rinoputika richiramba richikwira, Kupisa kunonzwisisika kunoshandiswa kupa kutonhora kwepamusoro-kudzvanywa. liquid gasi rechisikigo, uye musiyano wetembiricha unotanga kushanda. Mushure mekunge yaderedzwa kusvika kune imwe kukosha, mvura inotonhora inosanganiswa neiyo yakaderera-tembiricha gasi pane inowedzeredza yekubuda kuti ienderere mberi nekupa kutonhora kweiyo system. The shoma tembiricha musiyano mukati inotonhora bhokisi iri panopisa kuguma, kunotonhora kuguma uye confluence throttled fluid uye kuwedzera mvura, Uyezve, avhareji tembiricha musiyano wokupisa exchanger zvakare shoma pane kuti nitrogen kuwedzera liquefaction cycle;
3） MRC: mutsauko wekupisa wekupisa wekushisa pane yakaderera-tembiricha kupera mukati mekupisa yekupisa idiki, uye mutsauko wetembiricha wakakura kana uri padyo neyakajairwa tembiricha. Izvi zvinonyanya nokuti isopentane inoshandiswa kutsiva butane mufiriji. Mushure mekunge yakaomeswa yakasanganiswa refrigerant yakanyoroveswa nemvura yegungwa, isopentane mufiriji inonyungudutswa kuita mvura. Mu throttled yakavhenganiswa refrigerant, isopentane inotanga kunyunguduka pane imwe tembiricha yepamusoro, ine hombe yakadzikama kupisa kwemhepo. Ichi chikamu chekutonhodza simba hachigoni kupedzwa kana gasi rechisikigo uye high-pressure yakavhenganiswa refrigerant mumhepo inopisa inotonhora, Nokudaro, kusiyana kwekushisa kwekushisa muchikamu ichi kwakakura. Zvisinei, kushandisa isopentane panzvimbo yebutane seyepamusoro yekubikira firiji haigoni kuderedza kushandiswa kwesimba chete, asiwo kuwedzera kupisa kwekushisa kwekushisa kusiyana, iyo inobatsira zvikuru kuhurongwa hwose;
Nekuwedzera kwenhamba yematanho ekutenderera kwefiriji, kushandiswa kwesimba kwefiriji system kunoderera, uye coefficient yefriji uye exergy exergy inowedzera, asi simba rekuwedzera kwenhamba yematanho pakushanda kwefriji inoderera. Kuwedzera kwemafiriji kutenderera matanho kuchawedzera kuomarara kwemaitiro uye kuderedza kushanda. Iwo akanakisa matanho efiriji masisitimu ane zviyero zvakasiyana zvakasiyana. Iyo yakakura chiyero chiri, ndipo zvakanyanya matanho akakwana ari;

MRC inosanganisira kutenderera ne precooling uye kutenderera pasina precooling. Precooling cycle inosanganisira yakachena refrigerant precooling uye yakasanganiswa refrigerant precooling. Mafiriji akasanganiswa muzvikamu izvi zvakakamurwa kuita zvikamu zvakasiyana. Mvura yakapatsanurwa kubva pachinhanho chimwe nechimwe yakanyungudutswa uye yakanyungudutswa kuitira firiji, uye gasi rakapatsanurwa rinoramba richinyoroveswa uye rakaparadzaniswa. Matanho ekuparadzanisa akasiyana, kuoma kwemaitiro kwakasiyana, uye kushanda kwefiriji kutenderera kwakasiyana;
37, Mukugadzira dhizaini yeMRC, zvinodikanwa kukwidziridza chimiro chemaitiro uye sarudza yakakodzera nhamba yekutenderera. MRC inosanganisira imwe-nhanho MRC, mbiri-nhanho MRC, nhatu-nhanho MRC uye dzakawanda-nhanho MRC. Aya mafiriji kutenderera ari kushandiswa parizvino. Matanho akasiyana efiriji kutenderera, akasiyana mashandisirwo emagetsi efiriji uye kuomarara kwakasiyana kwemaitiro kunoda kusarudzwa zvinoenderana neyakasiyana chiyero chekugadzirisa. MRC optimization inosanganisira optimization yemaitiro uye process parameter optimization;
