lng ukuhlelwa kwetanki yokugcina i-cryogenic

I-tank yokugcina i-LNG cryogenic ifunyenwe ngokucoca igesi yendalo, ukuyicinezela kunye nokufudumeza kwayo, kunye nokususa i-N2, i-CO2, i-H2O, i-sulfide, ukungcola okuqinileyo, njl njl phantsi kwesenzo se-refrigerant edibeneyo, kwaye ekugqibeleni ifumane i-LNG kwindlela yolwelo -162 ° C. Emva kwenkqubo ye-liquefaction engentla, umthamo wegesi yendalo uncitshiswe ngamaxesha angama-600. I-LNG idla ngokugcinwa kwitanki yokugcina i-cryogenic kwi--162 ° C kunye noxinzelelo malunga ne-0.1 MPa.

(1) Ukuhlelwa kweIitanki zokugcina i-LNGngokomthamo
①Itanki yokugcina encinci: Umthamo yi-5 ~ 50m³. Ihlala isetyenziswa kwiindawo zokuzalisa izithuthi zeLNG kunye nezikhululo zokunyibilikisa irhasi.
② Iitanki zokugcina ezinobungakanani obuphakathi: 50 ~ 100m³, ubukhulu becala zisetyenziswa kwizikhululo zokunyibilikisa igesi kwimizi-mveliso.
③Itanki enkulu yokugcina: Umthamo yi-100 ~ 1000m³, ilungele izibonelelo ezincinci zemveliso ye-LNG.
④Itanki enkulu yokugcina: umthamo we-10,000 ukuya kwi-40,000 m³, esetyenziselwa uhlobo lomthwalo osisiseko kunye nesixhobo sokunyibilikisa sohlobo lolawulo oluphezulu.
⑤ Itanki enkulu yokugcina enkulu: Umthamo yi-4 ~ 200,000 m³, kwaye isetyenziselwa isikhululo sokwamkela i-LNG.
Ngo-1995, umthamo wetanki yokugcina wagqitha kuma-200,000 m³, kwaye waphuhlisela umthamo omkhulu wetanki yokugcina.

(2) Ukuhlelwa kweetanki zokugcina i-LNG ngokwemilo
① Itanki engqukuva: Iqhele ukusetyenziswa kwiitanki zokugcina umthamo omncinci naphakathi (kodwa iitanki ezinkulu zokugcina zikwasebenzisa iitanki ezingqukuva).
② Itanki yeCylindrical: isetyenziswa kwiitanki zokugcina izinto ezahlukeneyo.

(3) Iitanki zokugcina i-LNG cryogenic zinokwahlulwa kwakhona zibe ziindidi ezimbini: uhlobo olungaphezulu komhlaba kunye nodidi oluphantsi komhlaba (a. Uhlobo olungaphantsi komhlaba; b. Uhlobo olupheleleyo lwangaphantsi komhlaba; c. Uhlobo lomngxuma ongaphantsi komhlaba) ngokwendawo apho zibekwe khona.(4) Ukuhlelwa kweetanki zokugcina i-LNG ngokwezinto zabo zokwakha
① Uhlobo lweBimetal: Itanki yangaphakathi kunye neqokobhe langaphandle zenziwe ngezinto zetsimbi. Itanki yangaphakathi yenziwe ngentsimbi engatyiwayo ye-cryogenic okanye i-aluminium alloy, kwaye i-casing yangaphandle yenziwe ngentsimbi.isitya soxinzelelos.
② Uhlobo lwefilimu: I-cylinder yangaphakathi yolu hlobo lwetanki yokugcina yenziwe nge-36Ni yensimbi enobunzima be-0.8 ~ 1.2mm.
③ Uhlobo lwekhonkrithi olugxininisiweyo: I-cylinder yangaphakathi yolu hlobo lwetanki yokugcina yakhiwe ngezinto zetsimbi ze-cryogenic, kwaye i-casing yangaphandle yakhiwe ngekhonkrithi egxininisiweyo.

(5) Isakhiwo setanki yokugcina i-LNG cryogenic
①Itanki yokugcina ethe nkqo: itanki encinci ethe nkqo ye-LNG ye-100m³ isetyenziswa njengesixhobo sokutofa igesi kwiimoto.
②Itanki yokugcina uhlobo lonyana-umama: Ngokwesiqhelo, iitanki zentombi ezintathu okanye ngaphezulu ziqhagamshelwe ngokunxuseneyo ukwenza itanki yangaphakathi ukuhlangabezana neemfuno zokugcina umthamo omkhulu wokugcina ulwelo. Ukwakhiwa kwayo kukuba iitanki zabantwana ezininzi (ngokuqhelekileyo ezi-3 ukuya kwi-7) zihlanganiswe ecaleni kwitanki enkulu yangaphandle (ekwabizwa ngokuba yitanki yomama). Amatanki angaphantsi aqhele ukuba nkqo kwitanki, kwaye umthamo wetanki encinci nganye ungaphezulu kwe-100 ~ 150m³. Itanki yangaphandle inemilo yecylindrical ene-arch ephantsi ethe nkqo ephantsi, kwaye uninzi lwazo ziitanki ezinkulu zokugcina ezinomthamo we-300 ~ 1000m³ kunye noxinzelelo olusebenzayo lwe-0.2 ~ 1.2MPa.
③ Itanki yokugcina engqukuva: iitanki zangaphakathi nezingaphandle zingqukuva. Uninzi ngama-200 ~ 1500m³, kwaye uxinzelelo lokusebenza yi-0.2 ~ 1.0MPa.
④ Iitanki zogcino oluqhelekileyo oluvalwe ngokupheleleyo: Iitanki zokugcina ngaphezulu komhlaba ezinomthamo wama-80,000 m³, ubukhulu becala zisetyenziselwa iitheminali zokufumana i-LNG (ubukhulu bomthamo wama-200,000 mm³)
