I-oxygen ewuketshezi, i-nitrogen eyi-liquid, i-liquid argon vacuum cryogenic liquid tank storage

Incazelo Yomkhiqizo:

Amathangi okugcina uketshezi lwe-Cryogenic ahlukaniswe ngohlobo lokufakwa kwe-vacuum powder kanye nohlobo lokufakwa kwempushana yasemkhathini.I-powder insulation isebenzisa impushana ephansi yokushisa eshisayo, i-fiber noma impahla yegwebu ukunciphisa okokufaka ukushisa.Kunezinhlobo ezimbili: enye iwukusetshenziswa kwe-powder ejwayelekile (ukufakwa enqwabelanisiwe) ngaphansi kwengcindezi yomoya, ungqimba lokufakelwa lushubile, futhi lugcwele i-nitrogen eyomile ukuze kugcinwe ukucindezela okuhle ukuvimbela umswakama ukuthi ungangeni kanye nokufiphala, futhi ilungele i-nitrogen ewuketshezi ngaphezu kwezinga lokushisa;Olunye uhlobo lwe-vacuum powder insulation ukususa isikhala esigcwele impushana ukunciphisa ukudluliswa kokushisa kwegesi.Ngesikhathi esifanayo, izinhlayiya ze-powder nazo zenza buthaka ukudluliswa kokushisa kwemisebe, okwenza ukushisa kokushisa kube ngcono.

Izinzuzo zomkhiqizo:

1. Iningi le-tank esezingeni eliphansi yokugcina ithangi lensimbi engagqwali lenziwe nge-TISCO, i-Baosteel noma abakhiqizi bekhwalithi efanayo, isilinda sangaphakathi namapayipi zonke zenziwe ngensimbi engagqwali ye-austenitic, futhi igobolondo langaphandle lenziwe nge-Q245R noma i-Q345R noma izidingo eziphakeme. , konke kuthengwe kwa-Anyang Iron and Steel, Handan Iron and Steel Kanye namanye amaqembu amakhulu okukhiqiza insimbi yasekhaya.Amapuleti amaningi agxilile futhi aboshwe kusukela esitshalweni sensimbi ukuze kuncishiswe izixhumanisi eziphakathi, futhi izinga lomkhiqizo lingaqinisekiswa.Ngenxa yokuthi umthamo wokuthenga mkhulu, izindleko zethu kufanele zibe ngaphansi ngokufanelekile.

2. Izinto ezisetshenziswayo ziphinde zihlolwe ngokuhambisana ne-GB150-2011 "Imikhumbi Yokucindezela", ukujiya, ukucaciswa nokubukeka, njll., kanye nokuqukethwe kwensimbi kwezinto ezingavuthiwe njengamathuluzi okuhlola ama-spectroscopic asetshenziselwa ukuhlaziywa kwe-spectral nokuhlola.Eminye imikhiqizo ikhiqizwa njengamaphaneli okuhlola umkhiqizo kanye nokuhlolwa kokusebenza kwemishini kwenziwa..

3. Inqubo entsha yokushisela, imishini yokushisela yokungena ejulile, ukushisela ohlangothini olulodwa kanye nokwakheka okuhlangene kabili kuthuthukise ukusebenza kahle komsebenzi, ukubukeka kuhle kakhulu, izinga lokufaneleka liphezulu kakhulu, futhi izinga lokuthola amaphutha liyisisekelo.Yonke i-welding ye-seams ye-circumferential isebenzisa i-welding ezenzakalelayo noma i-welding yokungena ejulile, futhi yonke i-welding seams yomkhumbi osezingeni eliphansi ihlolwe nge-radiographically ngokusho kwezinga.

4. Ukugoba kwepayipi kwenziwa emshinini wokugoba wepayipi we-CNC, oqinisekisa ngokuqinile usayizi wejometri wokugoba kwepayipi.Alikho ilunga lendololwane elisetshenziswayo, okunciphisa kakhulu ukumelana namapayipi futhi kuthuthukisa ubuhle besistimu yamapayipi angaphandle.

5. Ngaphambi kokulayisha isihlabathi, umswakama kanye nokungcola kungqimba lokufakelwa kushintshwa yi-nitrogen yokushisa eyomile ukuze kuqinisekiswe indawo eyomile futhi kunciphise umthombo wokukhipha umoya.

6. Thumela isihlabathi se-pearlescent esisanda kunwetshwa kusuka kumkhiqizi siye embonini ukuze sigcwaliswe, uqinisekisa ukoma kwesihlabathi se-pearlescent kanye nokwenza ngcono ukusebenza kahle kwe-vacuuming.Ukugcwaliswa kwesihlabathi separele kusebenzisa ubuchwepheshe bokugcwalisa i-high-frequency vibration, isilinganiso sokugcwalisa isihlabathi se-pearl siphakeme izikhathi ezingu-1.5, isihlabathi separele sifana futhi sigcwele, futhi umphumela wokulondoloza ukushisa muhle.

7. I-tank yokugcina ithatha inqubo yokushisa ukuze kuqinisekiswe ukuthi izinga lokushisa le-cylinder elingaphakathi lingaphezu kwama-degree angu-100.Ngokushisa ngaphakathi, igesi ikhishwa kusengaphambili, ukuze iqhwa elakhiwe esimweni se-vacuum lifakwe ngaphansi kwe-sublimated kusengaphambili futhi impilo ye-vacuum inwetshiwe.

8. I-Paint spray anticorrosion, sebenzisa i-epoxy zinc-rich primer, fafaza kabili, ubukhulu bufinyelela kuma-microns angu-80, bese upende ophakathi, sisebenzisa upende ophakathi kwensimbi yefu, futhi ngemva kokufafaza ama-microns angu-80 kabili, bese sifafaza i-acrylic polyurethane kabili Ngaphezulu. ijazi lihlanganisa ubuso;ukushuba okuphelele kwezingqimba ezintathu zopende cishe kungama-microns angu-240;iphakeme kakhulu kunenqubo yokufafaza upende yabakhiqizi abajwayelekile.

9. Izindawo zangaphakathi nezangaphandle zethangi langaphakathi lensimbi engenasici ziyawohloka futhi zivuthwe yi-pickling passivation.Igobolondo lensimbi ye-carbon steel liphathwa nge-shot blasting grit steel grit ukususa ukugqwala.Konke ukugqwala okungaphezulu kwethangi lokugcina kuyalahlwa, futhi ukugqwala okuningi kufakwa ebusweni bepuleti lensimbi.Imigodi emincane inokunamathela okuqinile ngemva kokufafaza upende ophansi ovimbela ukugqwala, okuthuthukisa kakhulu ikhwalithi yokulwa nokugqwala kapende.Akuqinisekisi kuphela ukubonakala kwe-tank yokugcina, kwandisa impilo yepende, kodwa futhi iqinisekisa impilo ye-vacuum.

10. Amavaluvu, ama-level gauge kanye nama-vacuum valves konke kwenziwa ekhaya, futhi i-Rosemount yamazwe ngamazwe, i-Wika, i-Helos, i-Best, njll. nayo ingakhethwa.

11. Ithangi lokugcina lamukela idizayini yevalvu yokuphepha ekabili, eyodwa eyokugcina ikhophi kanye neyokusetshenziswa;kukhona ama-valve okuphepha phakathi kwama-valve amabili epayipi ukuze kuqinisekiswe ukuphepha komkhiqizo.

12. I-cryogenic liquid oxygen enkulu, i-argon eyi-liquid, amathangi okugcina i-nitrogen ewuketshezi, amathangi okugcina e-LNG, namathangi okugcina i-carbon dioxide emakethe anenani elithile lemikhiqizo eqediwe nesiqediwe esitokweni, eqinisekisa izidingo zomsebenzisi ekwakheni. isikhathi ngokwezinga elikhulu.
