Vacuum Insulated Amapayipikanye Negesi Yemvelo Encibilikisiwe: Ubambiswano Oluphelele

Imboni ye-liquefied natural gas (LNG) ikhule kakhulu ngenxa yokusebenza kahle kwayo ekugcinweni nasekuthuthweni. Ingxenye ebalulekile ebambe iqhaza kulokhu kuphumelela ukusetshenziswa kwamapayipi afakwe ivacuum (I-VIP). Lamapayipi adlala indima ebalulekile ekugcineni i-cryogenic edingekayo ku-LNG. Lesi sihloko sihlola ukubaluleka kanye nokusetshenziswa kweI-VIPemkhakheni we-LNG, okugqamisa izici ezithuthukile nezinzuzo abazinikezayo.

Iqhaza Elibalulekile Lamapayipi Afakwe I-Vacuum Ezokuthutha ze-LNG

I-LNG kumele igcinwe emazingeni okushisa aphansi kakhulu, cishe -162°C (-260°F), ukuze ihlale iwuketshezi.Vacuum amapayipi afakiwezenzelwe ukuphatha lezi zimo ze-cryogenic. Lawa mapayipi ahlanganisa insimbi engagqwali ezungezwe ibhantshi langaphandle, elinesikhala phakathi esinciphisa kakhulu ukudluliswa kokushisa. Lo mklamo uqinisekisa ukuthi i-LNG ihlala ezingeni lokushisa elizinzile ngesikhathi sokuthutha, inciphisa ukulahlekelwa kwe-boil-off gas (BOG) futhi ithuthukisa ukuphepha nokusebenza kahle.

Izici Eziyinhloko Zamapayipi Afakwe I-Vacuum

Vacuum amapayipi afakiwe, njengalezo ezikhiqizwe nguI-Holy Cryogenic Equipment Co., Ltd., bonisa izici ezimbalwa ezibalulekile:

● Material: Amapayipi angaphakathi enziwe kusukela ku-300 uchungechunge lwensimbi engagqwali, eyaziwa ngamandla ayo kanye nokumelana nokushisa kwe-cryogenic.
● I-insulation: Isikhala sevacuum sivame ukugcwaliswa ngezendlalelo eziningi zezinto ezibonisa ukukhanya njenge-aluminium foil, enciphisa nakakhulu ukudluliswa kokushisa ngemisebe. Ukwengeza, lesi sikhala siqukethe ama-adsorbent kanye nama-getter okugcina i-vacuum futhi amunce noma imaphi amagesi ayinsalela.
● Ukuxhuma: Lawa mapayipi angaxhunywa kusetshenziswa kokubili ama-flange kanye nokushisela, okuhlinzeka ngokuguquguquka ekufakeni nasekugcinweni.
● Ukusebenza kahle: Ukufakwa kwe-vacuum kuqinisekisa ukungena okuncane kokushisa, kunciphisa isidingo sokuphindaphinda kaningi noma ukukhishwa kabusha kwe-LNG.

Izicelo Nezinzuzo Embonini ye-LNG

Ukusetshenziswa kwama-VIP embonini ye-LNG kusabalele ngenxa yezakhiwo zawo eziphakeme zokuvikela ukushisa. Lawa mapayipi anenzuzo ikakhulukazi kulezi zindawo ezilandelayo:

● Amatheminali e-LNG:Ama-VIPusizo ekugcineni i-cryogenic edingekayo yokugcina i-LNG nokudlulisa, ukunciphisa izindleko zokusebenza ezihambisana nokulahlekelwa ukushisa.
● Ezokuthutha: Kungakhathaliseki ukuthi ngomkhumbi, iloli, noma ujantshi,Ama-VIPqinisekisa ukuthi i-LNG ihlala isesimweni esiwuketshezi kulo lonke uhambo, ivimbela ukulahlekelwa futhi igcina ukuphepha.
● Ukusetshenziswa Kwezimboni: Ezikhungweni lapho i-LNG isetshenziswa khona njengophethiloli noma njengesitoko, ama-VIP ahlinzeka ngezindlela ezithembekile zokuthutha igesi ezingxenyeni ezihlukene zesikhungo ngaphandle kokuguquguquka okukhulu kwezinga lokushisa.
