Twubaka imiyoboro yacu ya helium y'amazi dukoresheje uburinzi bwa azote y'amazi kugira ngo tugabanye ubushyuhe buva mu bushyuhe bw'icyumba kugeza ku murongo wa helium ya 4 K. Uburinzi buri kuri 77 K, bukora nk'uburinzi bw'ubushyuhe; bufata ubushyuhe bwinshi bw'imirasire n'ubuyobora mbere yuko bugera kuri helium. Muri HL Cryogenics, ubu buryo bwongera ingufu, burinda helium kubira vuba cyane, kandi bugafasha imiyoboro miremire yo kohereza ibintu gukora neza kandi neza. Uzasanga uburinzi bwa LN₂ buri mu mwanya wacu.Umuyoboro urinda ubushyuhe mu cyumagushyiraho, ikikijwe n'ahantu ho gucukura umwuka neza.
Mu miyoboro minini ikoresha amashanyarazi, gusimbuka iyi nganzo yo hagati ntabwo ari amahitamo. Iyo bitabayeho, ubushyuhe buturuka ku mirasire n'umwuka utemba mu gice cy'amashanyarazi byakwibasira urusobe rwa helium, bigatuma habaho guhumeka vuba kandi bigatuma imikorere ihamye idashoboka.
Igishushanyo cyacu cyibanda ku buryo bw'ingenzi bwo kohereza ubushyuhe—imirasire, kohereza, n'ingufu nke zisigaye. Ingufu ikuraho konveksiyo, ariko imirasire iracyasunika ubushyuhe mu bice bikonje cyane. Niho ubwikingo bwa azote bwinjirira. Kuri 77 K, ifata ingufu nyinshi, bityo igice gito gusa kigera kuri heliyumu. Ku miyoboro ifite ubwikingo buhanitse—cyane cyane muri sisitemu zisaba kohereza amazi ashyushye—iyi ngafu ya azote ntabwo ari ingirakamaro gusa; ni igice cy'ingenzi cy'ubuhanga. Ni yo ituma sisitemu igumana umutekano, ikora neza, kandi ihendutse mu gihe cyose cy'akazi kayo.

Ariko, mu buhanga bwacu, LN2 Shield ubwayo si igice cyigenga ahubwo ni igice cy’imiyoboro yose ya cryogenic. Ubusanzwe, iyi subsystem ikoreshwa hamwe n’imiyoboro yacu.Umuyoboro urinda ubushyuhe mu cyuma, Inzu yoroshye ifungishwa ibyuma bishyushyae, naValve ikingira umwukasisitemu zo gukora sisitemu yuzuye yo kugenzura ubushyuhe. Bitewe n'icyiciro cy'umushinga n'ibisabwa n'umuvuduko, uruziga rw'inkingo rushobora gushyirwa ku murongo umwe cyangwa ugororotse.
Mu gihe ikoreshwa mu buryo buhindagurika cyangwa igihe kirekire,Sisitemu yo gupompa ikoresha umwuka ushyushyeikoreshwa mu kurinda ko umwuka uva mu miyoboro ukomeza kubaho. Izatuma imiterere y’uburinzi bw’umuyoboro itazahungabana bitewe n’amazi make cyangwa imyuka isohoka mu gihe runaka. Gukoresha uburyo bwa LN2 bwo kurinda no gukwirakwiza umwuka uva mu miyoboro biduha ubushobozi bwo kohereza ubushyuhe buke cyane.
●Imikorere y'ubushyuhe n'imyitwarire yo gukingira umwuka uva mu cyuma gishyuha
Mu guhuzaSisitemu yo gupompa ikoresha umwuka ushyushye, Valve ikingira umwuka, naIgitandukanya Icyiciro, tuguha uburyo bwo gutwara heliyumu y'amazi neza kandi bugabanye ibiciro.Ikigega gitonaImiyoboro yoroshyereka dukore akazi kagendanwa n'ako mu buryo buhamye.
Mu rwego rw'ubuhanga, ubushobozi bw'ingabo ishingiye kuri azote y'amazi buterwa n'umwuka uva mu kirere, umwuka uva mu bikoresho, n'imiterere y'ubushyuhe bufata. Umuyaga uri mu bikoresho byacu bya HL Cryogenics wagenewe gukora hagati ya 10⁻³ - 10⁻⁶ Pa. Mu gihe cy'umuvuduko nk'uwo, gazi ishobora kwirengagizwa, kandi imirasire ni yo nzira nyamukuru yo kohereza ubushyuhe.
Iyo ukoresheje urwego rw'uburinzi bwa azote bukonje, ubushobozi bwo kohereza ubushyuhe bugabanuka kugeza kuri 70-90% ugereranyije n'uburinzi bumwe bw'umwuka. Ibyo bituma habaho imikorere myiza yaUmuyoboro urinda ubushyuhe mu cyumano kugabanuka k'ubushyuhe mu bijyanye na sisitemu za helium. Mu mishinga minini, ndetse no kwiyongera gato k'ubushyuhe bugabanuka bituma habaho kuzigama ku buryo bugaragara mu bukungu bitewe n'igiciro cya helium kiri hejuru.
Guhitamo ibikoresho nabyo ni ingenzi. Dukoresha icyuma kitagira umugese (304L na 316L nizo zikunzwe cyane), kubera ko gifite ubushyuhe buke n'imbaraga nke mu bushyuhe bukabije ndetse n'ubushobozi bwo guhuza ibikoresho. Ibikoresho byacu byose byujuje ibisabwa bya ASME, CE, na ISO ku byerekeye imiyoboro y'umuvuduko w'amashanyarazi ndetse n'ubuhanga bwa cryogenic.
●Uruhare rwo gushyigikira sisitemu nto zitera indwara z’umwijima
Agakingirizo ka azote ntigakora neza nta buryo bwa cryogenic. Tubifashijwemo n'umuryango wacu wa HL Cryogenics, kimwe mu bikoresho twakoze cyitwaIgitandukanya cy’imashini gikoresha amashanyarazi ashyushye.Ni ingenzi cyane mu gutuma amazi atemba mu byiciro bibiri kandi akarinda umwuka gufunga imiyoboro ikwirakwizwa.
Byongeye kandi, igishushanyo mbonera cyaValve ikingira umwukaigamije gutanga uburyo bworoshye bwo kugenzura ubushyuhe ariko igakomeza kugenzura neza uburyo amazi anyuramo mu gihe ubushyuhe buri hejuru butandukanye. Gukoresha ibikoresho nk'ibi biba ingenzi cyane mu miyoboro ya azote y'amazi n'imiyoboro ya heliyumu y'amazi ifite imitwaro itandukanye.
Ikindi gikoresho gikunze gushyirwa mu miyoboro ya cryogenic y'ingano nini niIkigega gitosisitemu. Hamwe n'uburyo bwacuSisitemu yo gupompa ikoresha umwuka ushyushye, bitanga uburinganire hagati y'umuvuduko, ubushyuhe, n'ikwirakwizwa ry'ibice.
Imiterere y'ibikorwa by'ubwubatsi mu buryo bufatika
Mu mushinga umwe wa LNG mu majyepfo y'uburasirazuba bwa Aziya, twagombaga kwimura heliyumu y'amazi mu ntera ndende—kandi kugabanya igihombo cy'ubushyuhe byari ingenzi cyane. Uburyo bwo kugarura heliyumu bwari buke, bityo gutakaza n'umutungo muto byasobanuraga ubusa. Kugira ngo tubikemure, twubatse sisitemu yo gukingira imyuka ifite ibyiciro bibiri: twakoreshejeUmuyoboro urinda ubushyuhe mu cyumakandi hongewemo uburyo bwo kurinda azote y'amazi.
Ikirere cyo mu majyepfo y'uburasirazuba bwa Aziya ntigikunda abantu barwaye indwara ziterwa n'izuba. Ubushyuhe bwakundaga kuzamuka burenga dogere selisiyusi 35, kandi ubushyuhe bwari bwinshi, ariko sisitemu yakomeje gukora neza. Ibintu byose bimaze gukora, twabonye igabanuka rikomeye rya helium rigabanuka ugereranije n'uko twari twiteze tudafite ubwishingizi bwa azote y'amazi.Sisitemu yo gupompa ikoresha umwuka ushyushyeyakoze akazi kayo—urugero rw’imyanda rwagumaga ruhamye mu gihe cyose twakoraga tudahagarara. Igihe cyose twakeneraga gukora isuku, Valves zikingira imyanda zatwikirije umwuka zatumaga dushobora gutandukanya ibice by’imiyoboro mu buryo butekanye.
Urebye imibare, biragaragara: gukoresha ubushyuhe mu byiciro byinshi si inyigisho gusa. Mu bice nka za terminal za LNG n'inganda za semiconductor, ni ngombwa. Guhagarara kw'imikorere si ikintu cyo ku ruhande—bigaragaza uburyo ibi bikoresho bishobora gukora neza.
Muri HL Cryogenics, twubaka sisitemu zo kurinda azote y'amazi zigira uruhare runini mu buhanga bwa cryogenic bw'iki gihe—cyane cyane iyo bigeze ku miterere ya heliyumu y'amazi aho kubungabunga ubushyuhe mu buryo buhamye ari ingenzi cyane. Dushyiraho uburyo bwo gukingira bugezweho, ibice byakozwe neza, kandi dukurikiza amahame akomeye yo gukora, bityo sisitemu zacu zigakora neza mu mishinga ya gaze y'inganda ku isi yose.
Buri gihe duhora dutunganya imiyoboro yacu ikoresha amashanyarazi ashyushye, imiyoboro yoroshye, kandi dushyigikira sisitemu nto zikoresha amashanyarazi kugira ngo zikore akazi katoroshye mu nganda za LNG, mu nganda zikora ibikoresho bya semiconductor, no mu mishinga y’ingufu za hydrogen hirya no hino mu Burayi, muri Aziya no mu Burasirazuba bwo Hagati.
Niba ukeneye igisubizo cy’ikoranabuhanga gihuye n’umushinga wawe, cyangwa niba ushaka kuvuga ku bijyanye no gushushanya sisitemu, twiteguye kuganira ku bya tekiniki na ba rwiyemezamirimo ba EPC, injeniyeri, n’amatsinda ashinzwe gutanga amasoko.
