Cryogenic air separation tekinoroji ndiyo imwe yenzira dzakakosha dzekugadzira yakakwirira-kuchena nitrogen uye oksijeni muindasitiri yemazuva ano. Iyi tekinoroji inoshandiswa zvakanyanya mumaindasitiri akasiyana senge simbi, makemikari engineering, uye mushonga. Ichi chinyorwa chichaongorora zvakadzama kuti kupatsanurwa kwemhepo kwe cryogenic kunobudisa sei-yakachena nitrogen uye oksijeni, pamwe chete nematanho anokosha uye midziyo inobatanidzwa mukuita.

1. Nheyo yekutanga ye cryogenic air separation

Cryogenic air separation inzira inoparadzanisa zvikamu zvikuru zvemhepo nekudzikisa tembiricha. Mhepo inonyanya kuve nenitrogen, okisijeni, uye shoma shoma yeargon. Nekudzvanyirira nekutonhodza mhepo kusvika kune tembiricha yakaderera zvakanyanya, mhepo inonyungudutswa, uye ipapo nzvimbo dzekufashaira dzakasiyana dzegasi rega rega dzinoshandiswa kuita distillation kuparadzanisa nitrogen neokisijeni. Nzvimbo yekuvira yenitrogen ndeye -195.8 ℃, uye iyo yeokisijeni i -183 ℃, saka vanogona kucheneswa zvakasiyana kuburikidza nekuita distillation.

2. Pre-kurapwa danho: Kucheneswa kwemhepo

Mune cryogenic mhepo yekuparadzanisa maitiro, mweya pre-kurapwa inhanho yekutanga yakakosha. Mhepo ine tsvina yakaita seguruva, carbon dioxide, uye mwando, izvo zvinozoomesa nechando munzvimbo yakaderera-tembiricha, zvichikonzera kuvharika kwemidziyo. Nokudaro, mhepo inotanga kuiswa pasi pekusefa, kudzvanywa, uye kuomesa matanho ekubvisa tsvina nehunyoro. Kazhinji, dryers uye molecular sieve adsorbers zvakakosha zvinoshandiswa kubvisa tsvina kubva mumhepo, kuve nechokwadi chekugadzikana uye kushanda kweiyo inotevera cryogenic separation process.

3. Kudzvanywa kwemhepo uye kutonhora

Mhepo yakanatswa inoda kudzvanywa, kazhinji kuburikidza nemacompressor akawanda kuti uwedzere kudzvanywa kwemhepo kusvika ku5-6 megapascals. Mhepo yakamanikidzwa inobva yatonhodzerwa kuburikidza nezvinopisa zvinopisa negasi rakadzoka pane tembiricha yakaderera, zvishoma nezvishoma ichideredza tembiricha kuti iswedere kune liquefaction point. Muchiitiko ichi, zvinopisa zvinopisa zvinoita basa rakakosha, sezvo zvichikwanisa kuderedza kushandiswa kwesimba uye kuvandudza kutonhora, kuve nechokwadi chekuti mhepo inogona kunyungudutswa pasi pemamiriro ekunze ekupisa, zvichipa mamiriro ekuzotevera kuparadzaniswa kwe distillation.

4. Air liquefaction uye distillation

Mune cryogenic separation tower, mweya wakamanikidzwa uye wakatonhodzwa unowedzera kutonhodzwa kusvika kune liquefied state. Iyo liquefied air inotumirwa kune distillation tower kuti iparadzane. Iyo distillation tower yakakamurwa kuita zvikamu zviviri: iyo yakakwirira-yekumanikidza shongwe uye yakaderera-kumanikidza shongwe. Mune iyo yakakwirira-kudzvanywa shongwe, mhepo inopatsanurwa kuita isina kuchena okisijeni uye isina kuchena nitrogen, uye ipapo iyo isina kuchena okisijeni uye isina kuchena nitrogen inowedzerwazve mushongwe yakaderera-kudzvanywa kuti iwane yakakwirira-kuchena oksijeni uye nitrogen. Kupatsanurwa kwenitrogen neokisijeni kunonyanya kushandisa zvakasiyana-siyana zvemuviri zvemapoinzi ekuvira, saka kupatsanurwa kwakanaka kunogona kuwanikwa mushongwe yedistillation.

5. Kuchenesa nzira

Iyo okisijeni nenitrogen zvakapatsanurwa mushongwe yedistillation zvichine hutsvina hudiki, saka dzinoda kucheneswa kuti dzisangane nemaindasitiri nemishonga. Kuchena kwenitrogen kunogona kuvandudzwa kuburikidza nehydrogen deoxygenation catalysts, nepo kuchena kweokisijeni kunogona kuwanikwa kuburikidza ne-re-distillation maitiro. Kuti uvandudze kuchena kwegasi rechigadzirwa, midziyo yakadai senitrogen yekuchenesa uye okisijeni yekuchenesa inowanzoshandiswa, pakupedzisira ichiwana yakakwirira-kuchena okisijeni uye nitrogen zvigadzirwa.

6. Kushandiswa kwenitrogen neokisijeni

Yakakwirira-kuchena nitrogen uye okisijeni inogadzirwa ne cryogenic air separation tekinoroji inoshandiswa zvakanyanya mumaindasitiri akawanda. Yakanyanya-kuchena nitrogen inoshandiswa muindasitiri yemakemikari segasi rinodzivirira uye gasi rinotakura, muindasitiri yezvekudya kuchengetedza uye kurongedza, uye okisijeni inoshandiswa zvakanyanya muindasitiri yezvokurapa uye welding. Muindasitiri yemetallurgical, okisijeni inoshandiswawo kuvandudza kugona kwekupisa uye kuderedza kuburitsa kabhoni. Mumashandisirwo aya, kuchena kwegasi ndiyo kiyi yekuona kushanda kwayo, uye tekinoroji yekuparadzanisa mhepo ye cryogenic yakawana kucherechedzwa kwakakura kwekupatsanurwa kwayo kwakanaka uye kuchena kwepamusoro.

7. Zvakanakira uye zvinonetsa zve cryogenic air separation technology

Cryogenic air separation tekinoroji inofarirwa muindasitiri yeindasitiri nekuda kwekuchena kwayo kwakanyanya uye kugona kwakanyanya. Nekudaro, tekinoroji iyi inotarisanawo nemamwe matambudziko, akadai sekushandiswa kwesimba rakawanda uye mitengo yakakwira yekugadzirisa michina. Kuderedza kushandiswa kwesimba, yemazuva ano cryogenic mhepo yekuparadzanisa michina inowanzouya neyepamberi-ekuchengetedza simba masisitimu, senge maturusi ekudzoreredza kupisa uye akawanda-nhanho compression kutonhora masisitimu. Uyezve, kushandiswa kweautomation control tekinoroji kwakawedzera zvakanyanya mashandiro ekushanda uye kuchengetedzeka kweyakadzika cryogenic mhepo yekuparadzanisa zvikamu. Kuburikidza nekugadzirisa tekinoroji uye kuvandudzwa kwemidziyo, simba resimba uye kugadzikana kweyakadzika cryogenic mhepo yekuparadzanisa masisitimu zvakaramba zvichivandudzwa, zvichiwedzera kukurudzira kushandiswa kwavo mumaindasitiri akasiyana.

Deep cryogenic air separation iye zvino ndiyo imwe yenzira dzakanakisisa dzekubudisa high-purity nitrogen uye oksijeni. Inonyatsoparadzanisa uye inonatsa okisijeni uye nitrogen kubva kumhepo kuburikidza nematanho akawanda akadai sekutanga kurapwa kwemhepo, kudzvinyirira, kutonhora, liquefaction, uye distillation. Kunyangwe iyo yakadzika cryogenic mhepo yekuparadzanisa maitiro ine yakakwira simba rekushandisa uye yakaoma midziyo, yayo inoshanda yekuparadzanisa mhedzisiro uye yakakwirira-kuchena kwechigadzirwa kubuda kunoita kuti tekinoroji iyi ive yakakosha mumaindasitiri akawanda.
