Kuwonongeka kwa Ammonia

Kupanga kwa hydrogen kwa kuwonongeka kwa ammonia kumatenga ammonia yamadzimadzi ngati zopangira.Pambuyo pa vaporization, mpweya wosakanikirana womwe uli ndi 75% haidrojeni ndi 25% nayitrogeni umapezeka mwa kutenthetsa ndi kuwola ndi chothandizira.Kupyolera mu kugwedezeka kwachitsulo, hydrogen yokhala ndi 99.999% yoyera imatha kupangidwanso.

Kuwonongeka kwa Ammonia

Kupanga kwa hydrogen kwa kuwonongeka kwa ammonia kumatenga ammonia yamadzimadzi ngati zopangira.Pambuyo pa vaporization, mpweya wosakanikirana womwe uli ndi 75% haidrojeni ndi 25% nayitrogeni umapezeka mwa kutenthetsa ndi kuwola ndi chothandizira.Kupyolera mu kugwedezeka kwachitsulo, hydrogen yokhala ndi 99.999% yoyera imatha kupangidwanso.

Mfundo ya Kuwonongeka kwa Ammonia

Kutentha kwa Ammonia
Madzi ammonia otuluka mu botolo la ammonia amalowa mu vaporizer ya ammonia poyamba.Kugwiritsa ntchito madzi osamba kutentha kwa vaporization, ndi vaporizer ndi chubu-mapepala kutentha exchanger.Ammonia amaperekedwa kumbali ya chubu, ndipo mbali ya chipolopolo ndi madzi otentha otenthedwa ndi chowotcha chamagetsi.Madzi otentha ndi ammonia amadzimadzi amasinthanitsa kutentha kuti asungunuke ammonia amadzimadzi kukhala ammonia agasi ndi 1.5MPa ndi 45 ℃.Ammonia wa gaseous amachepetsedwa kuchokera ku 1.5MPa kupita ku 0.05Mpa ndi kukakamiza kuchepetsa valavu kuti asinthe kutentha ndi mpweya wotentha kwambiri kuchokera ku ng'anjo yowonongeka, ndiye ammonia wotenthedwa amalowa m'ng'anjo yotentha kwambiri.

Kuwonongeka kwa Ammonia
Ng'anjo yowonongeka imapangidwa ndi ng'anjo yamagetsi ndi ng'anjo yowonongeka.Ng'anjo yamagetsi imaphatikizapo zinthu zotenthetsera zamagetsi, zida zokanira, zida zotchingira matenthedwe, ma thermistors ndi zida zamagetsi zamagetsi.Mwa njira, magetsi Kutentha zinthu faifi tambala chromium aloyi Cr20Ni80, amene ndi yabwino magetsi Kutentha aloyi zakuthupi.Zida zopangira matenthedwe zimapangidwa ndi njerwa zodziwika bwino za aluminium silicate fiber.
Kuwonongeka kwa ng'anjo yamoto ndiye gawo lalikulu la kuwonongeka kwa ammonia.Ammonia amaphwanyidwa mu hydrogen nitrogen osakaniza pa kutentha kwakukulu ndi chothandizira mu ng'anjo yowola.Mng'anjo ya ng'anjo imatha kupirira kutentha kwanthawi yayitali kwa 900 ℃ ndi dzimbiri kuchokera ku ammonia.Chifukwa chake, pogwiritsa ntchito aloyi yosagwirizana ndi kutentha kwambiri monga cholumikizira cha ng'anjo, ndipo choyatsira ng'anjo chimapanga mawonekedwe a U okhala ndi nickel chothandizira kwambiri.Ammonia amawola kukhala mpweya wosakanikirana wokhala ndi 75% haidrojeni ndi 25% wa nayitrogeni wokhala ndi chothandizira kutentha kwambiri.
The chemical equation ndi 2NH3 → 3H2 + N2 - Q

Kuyeretsa kwa PSA / PSA Hydrogen Production
Mpweya wosakanizikawo umadutsa muchotenthetsera kutentha ndi kuzizira kwamadzi, kenako umalowa mu hydrogen purifier kuti uyeretsedwe.Kuyeretsedwa kumapangidwa ndi deaerator, cooler, molecular sieve adsorption dryer, gulu la valve ndi magetsi.
Malinga ndi mfundo ya pressure swing adsorption(PSA), pali zowumitsira ma molecular sieve adsorption, ndipo zowumitsira ma molecular sieve adsorption zimasinthidwanso.Wina ndi wokometsa zonyansa ndipo wina ndi wothira ndi kutulutsa zonyansa.

Njira Yakuwola kwa Ammonia

Zotsatira za Kuwonongeka kwa Ammonia

☆ Mtengo wotsika, kugwiritsa ntchito mphamvu ndi ndalama, kukula kochepa komanso kuchita bwino kwambiri.
☆ Kutentha kumayendetsedwa ndi wowongolera kutentha ndipo kutuluka kumayendetsedwa ndi valve.Choncho, ntchitoyo ndi yodalirika.
☆ Gwiritsani ntchito chothandizira chapamwamba kwambiri, chitsulo chosapanga dzimbiri chosatentha, nickel chromium alloy magetsi otenthetsera zinthu ndi ma valve zitsulo zosapanga dzimbiri.
☆ Zosavuta kugwiritsa ntchito ndikuyika popanda kumanga likulu, mawonekedwe ophatikizika ndi malo ang'onoang'ono apansi ngati mtundu wophatikizidwa wa skid.
☆ Mpweya ukhoza kugwiritsidwa ntchito momasuka mkati mwa magawo opangira gasi wokhala ndi chitetezo chokwanira.Nthawi zambiri, palibe chifukwa chosungira haidrojeni mu thanki yosungirako.
