Iyo cryogenic yekuchengetedza tangi yakashongedzerwa neyakaviri-level alarm interlock system

Cryogenic kuchengetedza matangianoshandiswa zvakanyanya muminda yemaindasitiri. Kuti kuve nechokwadi chekushandiswa kwakachengeteka kwematangi ekuchengetera cryogenic, chisimbiso che nitrogen chinofanira kuiswa pakati pemukati nekunze kwepakati petangi rekuchengetedza cryogenic kuchengetedza kudzvanywa kwakanaka kwepakati nepakati kudzivirira mhepo yakanyorova kuti isapinda uye kuve nechokwadi chakanaka chekupisa kupisa kuita kwemakemikari zvigadzirwa. Uye zvakare, ndeapi matanho ekuchengetedza ekuchengetedza anodiwa kune cryogenic kuchengetedza matangi?

Semuenzaniso, tangi yemukati ye cryogenic yekuchengetera tangi inofanirwa kunge ine seti yemvura level alarm inopindirana system. Kana iyo yemvura mwero weiyo cryogenic yekuchengetedza tangi yakakwira kupfuura kukosha kweseti, iyo yakakwira yemvura level alarm inomiswa, uye kana yakakwira yemvura level yasvika, iyo interlock system inomiswa. Dzima vharafu papombi yekupinza ye tanki yekuchengetera cryogenic.

Kana iyo yemvura nhanho mu cryogenic yekuchengetera tangi yakadzikira pane yakatarwa kukosha, yakaderera mvura level alarm inokonzereswa. Kana iyo yakaderera yemvura mwero yasvika, iyo interlock system inogadziriswa, vharafu pamvura yekuburitsa pombi ye cryogenic yekuchengetedza tank inogurwa, uye pombi yekurodha yakavharwa. Pamusoro pezvo, pachave nemaseti maviri ekudzvanywa kwekutarisa uye alarm inopindirana masisitimu. Kana kudzvinyirirwa kwetangi yekuchengetera cryogenic kwakakwira kupfuura kukosha kweseti, alarm-yekudzvanya inokonzeresa, iyo interlock system ichaitwa, uye otomatiki valve paLNG yekuchengetera tank pressurization system pombi ichagurwa. , Rega kuwedzera.Apo iyo cryogenic storage tank pressure yakaderera kudarika kukosha kwakatarwa, iyo yakaderera-yekumanikidza alarm ichagadziriswa uye kudzoka kwevhavha yeBOG compressor ichazarurwa kuti ione kuti kumanikidzwa mutangi yekuchengetedza hakuzogadziri kudzvinyirira kusina kunaka. Kana iyo yakaderera kudzvinyirirwa yasvika, iyo interlock system inogadziriswa, iyo otomatiki valve pane pombi ye cryogenic yekuchengetedza tank pressurization system inovhurwa, uye iyoliquid cryogenic storage tankinomanikidzwa kupinda mukati mekuchengetedza tangi.

Kwete izvozvo chete, iyo cryogenic storage tank inewo yakakwana yekuchengetedza hurongwa, kureva, maviri-boka rekuchengetedza valve uye maviri-boka rekufema valve, uye nzira nhatu inoshandiswa pakushandura. Kana iyo yemukati tangi yekumanikidza inodarika 25kPa, vharafu yekudzivirira inoburitsa uye kusunungura kumanikidza; apo tangi yemukati inodzvinyirira yakaderera kupfuura -0.5kPa, valve yekufema inovhura uye mhepo inopinda mukati me tank kuti ione kuti kukuvara kwemidziyo nematambudziko zvinodziviswa.
