1. Chidule cha zida za nayitrogeni zoyera kwambiri
Zida za nayitrogeni zoyera kwambiri ndiye gawo lalikulu la njira yolekanitsa mpweya wa cryogenic (cryogenic air separation). Amagwiritsidwa ntchito makamaka kulekanitsa ndi kuyeretsa nayitrogeni kuchokera ku mpweya, ndipo potsirizira pake amapeza zinthu za nayitrogeni moyera mpaka **99.999% (5N) kapena kupitirira apo**. Zipangizozi zimachokera ku teknoloji ya ** cryogenic distillation **, pogwiritsa ntchito kusiyana kwa kutentha pakati pa nitrogen (boiling point -195.8 ℃) ndi oxygen (boiling point -183 ℃) mumlengalenga, ndipo imakwaniritsa kulekanitsa koyenera kupyolera mu kutentha kochepa komanso kugawa.
Mkulu-chiyero nayitrogeni zida chimagwiritsidwa ntchito pa zamagetsi, makampani mankhwala, mankhwala, processing zitsulo, kusunga chakudya ndi madera ena, makamaka m'mafakitale apamwamba chatekinoloje monga semiconductor kupanga ndi lifiyamu batire kupanga, amene amafuna kwambiri mkulu nayitrogeni chiyero, ndi luso cryogenic mpweya kulekana ndi njira khola kwambiri ndi ndalama.
2. Zinthu zazikuluzikulu za zida za nayitrogeni zoyera kwambiri
1). Kutulutsa kwa nayitrogeni kopitilira muyeso
- The multistage distillation tower ndi luso lapamwamba la ma molecular sieve adsorption limatha kupanga mokhazikika 99.999% ~ 99.9999% (5N~6N) nitrogen yoyera kwambiri kuti ikwaniritse zofunikira za semiconductor, photovoltaic ndi mafakitale ena.
- Kufufuza mpweya, chinyezi ndi ma hydrocarbons amachotsedwanso kudzera mu cryogenic adsorption (PSA) kapena ukadaulo wa catalytic deoxygenation kuwonetsetsa kuti kuyera kwa nayitrogeni kukugwirizana ndi muyezo.
2). Kupulumutsa mphamvu ndi kothandiza, ntchito yokhazikika
- Zida zolekanitsa mpweya wa cryogenic zimagwiritsa ntchito chowonjezera + chotenthetsera kutentha kukhathamiritsa kuzungulira kwa firiji ndikuchepetsa kugwiritsa ntchito mphamvu. Poyerekeza ndi ukadaulo wolekanitsa wa membrane kapena ukadaulo wa pressure swing adsorption (PSA), mtengo wogwiritsa ntchito nthawi yayitali ndi wotsika.
- Dongosolo lodzilamulira lokha limayang'anira kutentha, kupanikizika ndi chiyero mu nthawi yeniyeni kuti zitsimikizire kuti zida zikuyenda bwino ndikuchepetsa kulowererapo pamanja.
3). Mapangidwe amtundu, kusinthasintha kwamphamvu
- Zing'onozing'ono (<100Nm³/h), zapakati (100~1000Nm³/h) kapena zazikulu (>1000Nm³/h) zida za nayitrogeni zitha kusinthidwa malinga ndi zosowa zamakasitomala, kutengera zosowa zamafakitale osiyanasiyana.
- Yoyenera kupanga nayitrogeni pamalo (On-site Generation), kuchepetsa mtengo wamayendedwe ndi kusunga wa nayitrogeni wamadzimadzi.
4). Otetezeka komanso odalirika, okonda zachilengedwe komanso otsika kwambiri
- Landirani mapangidwe osaphulika ndi chitetezo chambiri (monga kuwunika momwe mpweya uliri, chitetezo chambiri) kuti muwonetsetse kupanga bwino.
- Magetsi okha ndi mpweya zimadyedwa panthawi yosiyanitsa mpweya wozizira kwambiri, popanda kuipitsidwa ndi mankhwala, mogwirizana ndi miyezo yopangira zobiriwira.
3. Malo ogwiritsira ntchito kwambiri zida za nayitrogeni zoyera kwambiri
1). Makampani opanga zamagetsi ndi semiconductor
- Imagwiritsidwa ntchito popanga zowotcha, zoyika za LED, kupanga ma cell a photovoltaic, kupereka nayitrogeni yoyera kwambiri ngati gasi woteteza kuteteza okosijeni ndi kuipitsa.
- Mu semiconductor etching, chemical vapor deposition (CVD) ndi njira zina, nayitrogeni imagwiritsidwa ntchito ngati chonyamulira mpweya kapena kuyeretsa mpweya kuti zitsimikizire kukhazikika kwadongosolo.
2). Chemical ndi Energy Viwanda
- Amagwiritsidwa ntchito poteteza gasi wa inert m'mafakitale amafuta amafuta ndi malasha kuti apewe ngozi zoyaka komanso kuphulika.
- Imagwiritsidwa ntchito popanga batire ya lithiamu (monga kuyanika kwachidutswa, kuyika jekeseni wamadzimadzi) kuteteza chinyezi ndi mpweya kuti zisakhudze magwiridwe antchito a batri.
3). Makampani a Chakudya ndi Mankhwala
- Kupaka zakudya kumagwiritsa ntchito nayitrogeni woyengedwa kwambiri (woposa 99.9%) kuti atalikitse moyo wa alumali ndikuletsa makutidwe ndi okosijeni ndi kuwonongeka.
- Amagwiritsidwa ntchito m'makampani opanga mankhwala podzaza aseptic nayitrogeni komanso chitetezo cha biological agents, motsatira miyezo ya GMP.
4). Chithandizo cha Kutentha kwa Zitsulo ndi Kusindikiza kwa 3D
- Perekani malo osagwira ntchito mu annealing, quenching, brazing ndi njira zina kuti mupewe okosijeni wazitsulo.
- Amagwiritsidwa ntchito posindikiza zitsulo za 3D (ukadaulo wa SLM) kuti achepetse makutidwe ndi okosijeni a ufa ndikuwongolera mawonekedwe.
5). Kafukufuku wa Sayansi ndi Laboratory
- Perekani chilengedwe cha nayitrogeni chapamwamba kwambiri pakuyesa komaliza monga zida za superconducting ndi nuclear magnetic resonance (NMR).
4. Zochitika zachitukuko chamtsogolo
1). Intelligence ndi Internet of Zinthu (IoT) kuphatikiza
- Kupititsa patsogolo mphamvu zamagetsi zamagetsi ndi luso lokonzekera zolosera kudzera pakuwunika kwakutali komanso kukhathamiritsa kwa AI.
2). Green ndi otsika mpweya luso
- Kuphatikizika ndi mphamvu zongowonjezwdwa (monga mphamvu yamphepo, photovoltaic) mphamvu yamagetsi yochepetsera mpweya wa carbon.
3). Miniaturization ndi kupanga mafoni a nayitrogeni
- Pangani zida zopangira nayitrogeni za cryogenic zoyenera kugawa mphamvu ndi mafakitale ang'onoang'ono.
Chidule
Monga ntchito yofunikira yaukadaulo wolekanitsa mpweya wa cryogenic, zida za nayitrogeni zapamwamba zakhala zida zoyambira zaukadaulo wapamwamba wopanga komanso kupanga mafakitale ndi zabwino zake zachiyero chapamwamba kwambiri, kupulumutsa mphamvu ndi kukhazikika, chitetezo ndi chitetezo cha chilengedwe. Ndi chitukuko chofulumira cha mafakitale monga zamagetsi ndi mphamvu zatsopano, zida zoyera za nayitrogeni zidzapitirizabe kusinthika ku nzeru, mphamvu ndi kubiriwira, kupereka njira zodalirika za nayitrogeni pamakampani amakono.
