Ndi chitukuko chachangu cha mafakitale a mankhwala, mphamvu, zamankhwala ndi ena, kufunikira kwa mpweya wabwino kwambiri wamafakitale (monga mpweya, nayitrogeni, argon) kukupitilira kukula.Ukadaulo wolekanitsa mpweya wa Cryogenic, monga njira yokhwima kwambiri yolekanitsa mpweya waukulu, yakhala yankho lalikulu la makampaniwa chifukwa cha kugwira ntchito bwino komanso kukhazikika kwake. Nkhaniyi isanthula mfundo zake zaukadaulo, kusiyana kwa mitundu yosiyanasiyana ya ntchito ndi zofunikira zoyambira.
Poyerekeza ndi zida zolekanitsa mpweya wa gasi, zida zolekanitsa mpweya wamadzimadzi zimafuna mphamvu zambiri zoziziritsira. Malinga ndi mphamvu zosiyanasiyana zolekanitsa mpweya wamadzimadzi, timagwiritsa ntchito njira zosiyanasiyana zoziziritsira:kuziziritsa kwa turbine yowonjezera, kuziziritsa kwa precooler yotsika kutentha, kuziziritsa kwa compressor yozungulira kwamphamvu komanso kotsika kwa expander, ndi zina zotero, kuti akwaniritse cholinga chochepetsa kugwiritsa ntchito mphamvu pogwiritsa ntchito njira zosiyanasiyana. Dongosolo lowongolera limagwiritsa ntchitoDongosolo lowongolera la DCS kapena PLC, ndipo zimathandiza zida zakumunda kuti zida zonse zikhale zosavuta kugwiritsa ntchito, zokhazikika komanso zodalirika.
Zinthu zaukadaulo: Kupambana kwaukadaulo kwa cryogenic distillation
Ukadaulo wolekanitsa mpweya wamadzimadzi ozizira kwambiri umakanikiza ndi kuziziritsa mpweya kufika kutentha kochepa kwambiri (pansi pa -196°C) ndipo umagwiritsa ntchito kusiyana kwa kutentha kwa gawo lililonse kuti ukhale wosiyana. Ubwino waukulu ndi monga:
- Kutulutsa koyera kwambiri:Imatha kupanga 99.999% ya okosijeni woyera, nayitrogeni woyera ndi argon woyera kwambiri kuti ikwaniritse zosowa zapamwamba monga ma semiconductors ndi chithandizo chamankhwala.
- Kuchuluka kwa kupanga:Mphamvu yotulutsa ya tsiku ndi tsiku ya chipangizo chimodzi imatha kufika matani masauzande ambiri, zomwe ndizoyenera mafakitale olemera monga mafakitale achitsulo ndi mankhwala.
- Kukonza bwino mphamvu:Zipangizo zamakono zolekanitsa mpweya zimaphatikizapo ma compressor, ma expander ndi ma heat exchanger omwe amagwira ntchito bwino kwambiri, zomwe zimachepetsa kugwiritsa ntchito mphamvu ndi zoposa 30%.
Kusiyana kwa ntchito: Kufunika kwa mafakitale kumayendetsa kusiyana kwa ukadaulo
Makampani osiyanasiyana ali ndi zofunikira zosiyanasiyana pamakina olekanitsa mpweya wozizira kwambiri, omwe amagawidwa m'magulu otsatirawa:
Mtundu wa mafakitale wachikhalidwe
- Madera ogwiritsira ntchito:zitsulo, mankhwala a petrochemical.
- Mawonekedwe:Yang'anani kwambiri pa mpweya wothamanga kwambiri (monga chothandizira kuyaka chopangira zitsulo) kapena nayitrogeni (monga mpweya woteteza mankhwala), wokhala ndi matanki akuluakulu osungiramo zinthu ndi njira zoyendera mapaipi.
Mtundu wamagetsi wa kalasi yapamwamba kwambiri
- Madera ogwiritsira ntchito:semiconductors, photovoltaics.
- Mawonekedwe:Mpweya woyera kwambiri (zonyansa ≤ 0.1ppm) umafunika, ndipo nsanja zoyeretsera zinthu zokhala ndi magawo ambiri ndi ma module oyeretsera molondola amakonzedwa.
Mtundu wa chisamaliro chaumoyo
- Madera ogwiritsira ntchito:zipatala, mankhwala achilengedwe.
- Mawonekedwe:Kugogomezera kwambiri chitetezo ndi kupezeka mwachangu, nthawi zambiri kumakhala ndi matanki osungira mpweya wamadzimadzi ndi makina otenthetsera mpweya.
Mtundu watsopano wothandizira mphamvu
- Madera ogwiritsira ntchito:mphamvu ya haidrojeni, kugwidwa kwa kaboni.
- Mawonekedwe:krypton, xenon ndi ntchito zina zochotsera mpweya wosowa, zomwe zimagwirizana ndi unyolo wamakampani opanga mphamvu zobiriwira.
Kapangidwe koyambira: gawo loyambira la dongosolo lolekanitsa mpweya
Zida zonse zolekanitsa mpweya wozizira kwambiri nthawi zambiri zimakhala ndi zinthu zofunika izi:
1. Dongosolo lopondereza mpweya
Chokometsera cha centrifugal chokhala ndi magawo ambiri, chomwe chimapereka mphamvu yofunikira pakulekanitsa (0.5-1.0MPa).
2. Chipinda choziziritsira ndi kuyeretsa
Chotsukira cha molecular sieve chimachotsa zinthu zodetsa monga chinyezi ndi CO₂.
3. Zipangizo zapakati zoziziritsa kukhosi
- - Chosinthira kutentha chachikulu: kusinthana kutentha pakati pa mpweya ndi mpweya wa chinthu.
- - Nsanja yothira madzi yokhala ndi magawo awiri: kulekanitsa okosijeni/nayitrogeni mu nsanja yapansi, kuyeretsa kwina mu nsanja yapamwamba.
4. Firiji yowonjezera
Amapereka mphamvu yoziziritsira nthawi zonse kuti asunge malo otentha kwambiri.
5. Njira yosungira ndi kutenthetsa mpweya
Matanki osungira mpweya wa okosijeni/madzimadzi a nayitrogeni, mapampu a cryogenic ndi ma vaporizer.
Zochitika zamtsogolo: nzeru ndi kuchepa kwa mpweya woipa
Ukadaulo wapadziko lonse wolekanitsa mpweya ukupita patsogolo m'mbali ziwiri:
- Luntha:Konzani bwino momwe mphamvu zimagwiritsidwira ntchito pogwiritsa ntchito ma algorithms a AI ndikuwunika kuyera kwa mpweya nthawi yeniyeni.
- Zobiriwira:Gwiritsani ntchito mphamvu zongowonjezwdwanso kuti muyendetse ma compressor unit kuti muchepetse mpweya woipa.
Ngati mukufuna mpweya/nayitrogeni/argon, chonde titumizireni uthenga:
