Nayitrogeni wamadzimadzi ndi chinthu chopanda mtundu, chosanunkha, chosapsa, chosapsa komanso chozizira kwambiri chomwe chimapeza ntchito zambiri kuphatikiza kafukufuku ndi chitukuko.

Liquid Nayitrogeni Liquefaction:

Chomera cha Nayitrogeni chamadzimadzi (LNP) chimatulutsa mpweya wa nayitrojeni mumlengalenga wa mumlengalenga kenako ndikuwusungunula mothandizidwa ndi Cryocooler.

Pali njira ziwiri zomwe nayitrojeni imatha kusungunuka:

Pressure Swing Adsorption ndi Cryogenerator.

Distillation wa mpweya wamadzimadzi.

Mfundo yogwira ntchito ya Liquid Nitrogen Plant

Muchomera cha Liquid Nitrogen, mpweya wa mumlengalenga umayamba kupsinjidwa mpaka 7 bar pressure kukhala kompresa.Mpweya wozizira kwambiri uwu umakhazikika mufiriji yakunja.Kenako, mpweya wokhazikika wokhazikikawo umadutsa mu cholekanitsa chinyezi kuti mutseke chinyezi kuchokera mumlengalenga.Mpweya wouma wowumawu umadutsa m'masefa a carbon molecular sieves pomwe Nayitrojeni ndi Oxygen zimalekanitsidwa ndi mpweya.Nayitrojeni wolekanitsidwa ndiye amaloledwa kudutsa Cryocooler yomwe imaziziritsa mpweya wa Nitrogen kukhala wamadzimadzi pamalo owira a Nitrogen (77.2 Kelvin).Pomaliza, Nayitrogeni ya Liquid imasonkhanitsidwa muchombo cha Dewar komwe imasungidwa pazinthu zingapo zamafakitale.

Kugwiritsa Ntchito Nayitrogeni Yamadzimadzi

Nayitrogeni wamadzimadzi amagwiritsidwa ntchito pazinthu zambiri chifukwa cha kutentha kwake kotsika kwambiri komanso kutsikanso kwamphamvu.Zina mwazomwe zimagwiritsidwa ntchito ndi izi:

Amagwiritsidwa ntchito mu cryotherapy kuti achotse zovuta zapakhungu

Amagwira ntchito ngati gwero la gasi wouma kwambiri

Kuzizira ndi kunyamula zakudya

Kuzizira kwa ma superconductors monga mapampu a vacuum, ndi zida zina

Cryopreservation wa magazi

Cryopreservation of biological samples ngati mazira, umuna, ndi ma genetic zitsanzo za nyama.

Kusunga umuna wa nyama

Kuyika chizindikiro cha ng'ombe

Cryosurgery (kuchotsa maselo akufa mu ubongo)

Kuzizira mwachangu kwa madzi kapena mapaipi kuti ogwira ntchito azigwira ntchito pamene ma valve palibe.

Kuteteza zinthu ku okosijeni.

Kutchinjiriza kwa zinthu kuti zisakhale ndi mpweya.

Ntchito zina zomwe zimaphatikizapo kupanga chifunga cha nayitrojeni, kupanga ayisikilimu, kuzizira kozizira, maluwa omwe amasweka akagundidwa pamalo olimba.
