HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Ukadaulo wolekanitsa mpweya wa cryogenic ndi njira imodzi yofunika kwambiri yopangira nayitrogeni ndi mpweya wabwino kwambiri m'makampani amakono. Ukadaulo uwu umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga zitsulo, uinjiniya wa mankhwala, ndi zamankhwala. Nkhaniyi ifufuza mozama momwe kulekanitsa mpweya wa cryogenic kumapangira nayitrogeni ndi mpweya wabwino kwambiri, komanso njira zazikulu ndi zida zomwe zimagwiritsidwa ntchito pankhaniyi.

1. Mfundo yofunikira yolekanitsa mpweya wa cryogenic

Kulekanitsa mpweya wa cryogenic ndi njira yomwe imalekanitsa zigawo zazikulu za mpweya pochepetsa kutentha. Mpweya umakhala ndi nayitrogeni, mpweya, ndi argon pang'ono. Mwa kukanikiza ndi kuziziritsa mpweya kufika kutentha kochepa kwambiri, mpweyawo umasungunuka, kenako malo osiyanasiyana owira a mpweya uliwonse amagwiritsidwa ntchito poyeretsedwa kuti alekanitse nayitrogeni ndi mpweya. Malo owira a nayitrogeni ndi -195.8℃, ndipo a mpweya ndi -183℃, kotero amatha kuyeretsedwa padera kudzera mu distillation yokonzedwa pang'onopang'ono.

2. Gawo loyambirira la chithandizo: Kuyeretsa mpweya

Mu njira yolekanitsa mpweya wa cryogenic, kukonza mpweya wa preheat ndi gawo loyamba lofunika kwambiri. Mpweya uli ndi zinthu zosafunika monga fumbi, carbon dioxide, ndi chinyezi, zomwe zimaundana pamalo otentha kwambiri, zomwe zimapangitsa kuti zipangizo zitseke. Chifukwa chake, mpweyawo umayamba kusefedwa, kuponderezedwa, ndi kuuma kuti uchotse zinthu zosafunika ndi chinyezi. Nthawi zambiri, zowumitsira ndi zotsukira ma molecular sieve ndi zida zofunika kwambiri zomwe zimagwiritsidwa ntchito kuchotsa zinthu zosafunika mumlengalenga, kuonetsetsa kuti njira yolekanitsa cryogenic ikuyenda bwino komanso moyenera.

3. Kupondereza ndi kuziziritsa mpweya

Mpweya woyeretsedwa umafunika kuponderezedwa, nthawi zambiri kudzera mu ma compressor angapo kuti mpweya uwonjezere kuthamanga kwa mpweya kufika pa ma megapascal 5-6. Mpweya woponderezedwawo umaziziritsidwa kudzera mu ma heat exchanger ndi mpweya wobwezedwa pa kutentha kochepa, zomwe zimapangitsa kuti kutentha kuchepe pang'onopang'ono kuti kufikire pa liquefaction point. Munjira imeneyi, ma heat exchanger amagwira ntchito yofunika kwambiri, chifukwa amatha kuchepetsa kugwiritsa ntchito mphamvu bwino ndikuwonjezera mphamvu yozizira, kuonetsetsa kuti mpweya ukhoza kusungunuka pansi pa kutentha kochepa, zomwe zimapangitsa kuti pakhale njira yopatukana ndi distillation.

4. Kutulutsa madzi ndi kusungunula mpweya

Mu nsanja yolekanitsa cryogenic, mpweya wopanikizika ndi wozizira umazizidwanso mpaka kufika pamlingo wamadzimadzi. Mpweya wosungunuka umatumizidwa ku nsanja yosungunuka kuti ulekanitsidwe. Nsanja yosungunuka imagawidwa m'magawo awiri: nsanja yosungunuka ndi mpweya wochepa. Mu nsanja yosungunuka, mpweya umagawidwa kukhala mpweya woipa ndi nayitrogeni wosaphika, kenako mpweya woipa ndi nayitrogeni wosaphika zimathiridwanso mu nsanja yosungunuka kuti zipeze mpweya woipa ndi nayitrogeni wosaphika. Kulekanitsidwa kwa nayitrogeni ndi mpweya makamaka kumagwiritsa ntchito mawonekedwe awo osiyanasiyana a malo otentha, kotero kulekanitsidwa kogwira mtima kumatha kuchitika mu nsanja yosungunuka.

5. Njira yoyeretsera

Mpweya wa okosijeni ndi nayitrogeni wolekanitsidwa mu nsanja yoyeretsera akadali ndi zinthu zochepa zosafunika, kotero amafunika kuyeretsedwa kwambiri kuti akwaniritse miyezo ya mafakitale ndi zamankhwala. Kuyera kwa nayitrogeni kumatha kuwongoleredwa kudzera mu zoyambitsa mpweya wa hydrogen deoxygenation, pomwe kuyera kwa mpweya kumatha kupezeka kudzera mu njira zoyeretsera mpweya. Kuti mpweya wa chinthucho ukhale woyera, nthawi zambiri amagwiritsidwa ntchito zipangizo monga zoyeretsera nayitrogeni ndi zoyeretsera mpweya wa okosijeni, zomwe pamapeto pake zimapeza zinthu za mpweya wa okosijeni ndi nayitrogeni woyeretsedwa kwambiri.

6. Kugwiritsa ntchito nayitrogeni ndi mpweya

Nayitrogeni ndi mpweya wabwino kwambiri zomwe zimapangidwa ndi ukadaulo wolekanitsa mpweya wa cryogenic zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Nayitrogeni wabwino kwambiri amagwiritsidwa ntchito m'makampani opanga mankhwala ngati mpweya woteteza komanso wonyamula mpweya, m'makampani ogulitsa chakudya kuti asungidwe ndi kupakidwa, ndipo mpweya wabwino kwambiri umagwiritsidwa ntchito kwambiri m'makampani azachipatala ndi osokerera. M'makampani opanga zitsulo, mpweya umagwiritsidwanso ntchito kukonza bwino kuyaka ndikuchepetsa mpweya woipa wa kaboni. Mu ntchito izi, kuyera kwa mpweya ndiye chinsinsi chodziwira momwe ungagwiritsidwire ntchito, ndipo ukadaulo wolekanitsa mpweya wa cryogenic wadziwika kwambiri chifukwa cha kulekanitsa kwake bwino komanso kutulutsa kwake koyera kwambiri.

7. Ubwino ndi zovuta za ukadaulo wolekanitsa mpweya wa cryogenic

Ukadaulo wolekanitsa mpweya wa cryogenic umakondedwa kwambiri m'mafakitale chifukwa cha kuyera kwake kwakukulu komanso kugwira ntchito bwino. Komabe, ukadaulo uwu umakumananso ndi mavuto ena, monga kugwiritsa ntchito mphamvu zambiri komanso ndalama zambiri zosamalira zida. Pofuna kuchepetsa kugwiritsa ntchito mphamvu, zida zamakono zolekanitsa mpweya wa cryogenic nthawi zambiri zimakhala ndi njira zapamwamba zosungira mphamvu, monga zida zobwezeretsa kutentha ndi njira zoziziritsira zopondereza zambiri. Kuphatikiza apo, kugwiritsa ntchito ukadaulo wowongolera zokha kwawonjezera kwambiri magwiridwe antchito ndi chitetezo cha mayunitsi olekanitsa mpweya wa cryogenic. Kudzera mu kukonza ukadaulo ndi kukonza zida, kugwiritsa ntchito mphamvu bwino komanso kukhazikika kwa machitidwe olekanitsa mpweya wa cryogenic kwakhala kukusintha nthawi zonse, zomwe zikulimbikitsa kugwiritsa ntchito kwawo m'mafakitale osiyanasiyana.

Kulekanitsa mpweya wozama ndi njira imodzi yothandiza kwambiri popanga nayitrogeni ndi mpweya wozama. Kumalekanitsa ndikuyeretsa mpweya ndi nayitrogeni kuchokera mumlengalenga kudzera m'magawo angapo monga kukonza mpweya, kupondereza, kuziziritsa, kusungunula madzi, ndi kusungunula. Ngakhale njira yolekanitsa mpweya wozama ndi wozama imagwiritsa ntchito mphamvu zambiri komanso zida zovuta, mphamvu yake yolekanitsa bwino komanso kutulutsa zinthu zoyera kwambiri kumapangitsa ukadaulo uwu kukhala wofunikira kwambiri m'mafakitale osiyanasiyana.
