Liquid nitrogen uye liquid oxygen zvinhu zviviri zvinowanzo shandiswa cryogenic zvinwiwa muindasitiri nekutsvaga. Imwe neimwe ine yayo yakakura-siyana uye yakasarudzika maapplication. Ose ari maviri anogadzirwa kuburikidza nekupatsanurwa kwemhepo, asi nekuda kweakasiyana makemikari uye emuviri zvimiro, ane akasiyana hunhu mukushandisa zvinoshanda. Ichi chinyorwa chichaongorora mashandisirwo chaiwo emvura nitrogen uye mvura okisijeni uye mutsauko wavo.

I. Kushandiswa kweLiquid Nitrogen

Liquid nitrogen inowanikwa nemhepo inotonhodza kusvika pazasi penzvimbo yekuvira yenitrogen. Chinhu chayo chikuru initrogen gasi (N₂). Iyo yakaderera-tembiricha midziyo yenitrogen yemvura inoita kuti ishande zvakanyanya, kunyanya kusanganisira zvinotevera zvinhu:

Kutonhora kwepasi-tembiricha uye kuchengetedza

Imwe yeanonyanya kushandiswa emvura nitrogen ndeyekutonhora-kutonhora uye kuchengetedza, kunyanya mumunda webiomedicine. Tembiricha yenitrogen yemvura yakadzikira se -196 ° C, inogona kukurumidza kuomesa zvipenyu, masero, uye embryos uye kuzvichengetedza kwenguva yakareba, kuve nechokwadi chekuita kwavo. Zvikumbiro izvi zvine kukosha kukuru mukutsvaga kwekurapa, kuisirwa nhengo, uye kuedza kubereka mhuka.

Chikafu chinotonhora

Mundima yekugadzira chikafu, mvura ine nitrogen inoshandiswa kukurumidza kuomesa chikafu, sehove dzemugungwa, nyama, uye michero. Liquid nitrogen yechando inogona kukurumidza kudzikisa tembiricha yechikafu, nekudaro ichideredza kuumbwa kwemakristasi echando uye kuchengetedza kuravira uye kukosha kwekudya kwechikafu.

Kutonhodza uye firiji

Liquid nitrogen inowanzo shandiswawo kutonhodza uye tembiricha yekudzora midziyo yemuchina. Semuyenzaniso, mvura nitrogen inogona kushandiswa senge yekutonhodza svikiro kuderedza kukweshera uye kupisa mukugadzira mechanika, nekudaro kunatsiridza kurongeka nekunyatsoshanda.

Zvishandiso zvegasi nitrogen: Liquid nitrogen inogonawo kupa yakakwira-kuchena nitrogen gasi mushure mekuputika, iyo inoshandiswa zvakanyanya muindasitiri yemakemikari segasi rinodzivirira kudzivirira kuita oxidation yezvinhu zvinokuvadza.

II. Zvishandiso zveLiquid Oxygen

Chinhu chikuru cheokisijeni yemvura ndeye okisijeni (O₂), iyo inowanikwawo kuburikidza neyakadzama cryogenic yekuparadzanisa tekinoroji. Okisijeni, sechinhu chakakosha chekutsigira hupenyu uye kuita kwemakemikari, ine akasiyana maapplication, anonyanya kuratidzwa mune zvinotevera zvinhu:

Mushonga weokisijeni wekurapa

Liquid okisijeni inoshandiswa zvakanyanya muzvipatara uye nekuchengetedzwa kwekukurumidzira, kupa yakakwira-concentration oxygen kuvarwere kuti vabatsire kufema. Kunyanya mukurapa kwezvirwere zvekufema, kupihwa kweokisijeni kwakakosha. Liquid okisijeni idiki muhukuru, ine yakakwira okisijeni yemukati, yakanakira kuchengetedza uye kutakura, uye ndeimwe yemhando dzinofarirwa dzekurapa okisijeni.

Industrial oxidant

Liquid oxygen inowanzoshandiswa seoxidant muindasitiri, kunyanya mukunyungudutsa simbi uye kugadzira makemikari. Liquid okisijeni inogona kushandiswa kubatsira kupisa, kuwedzera kupisa kwekushisa uye kuita zvakanaka. Somuenzaniso, mukugadzira simbi, okisijeni inoiswa mumvura yesimbi yakanyunguduka kuti ibvise tsvina uye kunatsiridza kuchena kwesimbi.

Aerospace uye rocket propulsion

Liquid okisijeni imafuta ekubatsira anowanzo shandiswa mumaroketi propulsion masisitimu, akasanganiswa nemafuta emvura (semvura yehydrogen) pakupisa, achigadzira simba rakawandisa rekusunda maroketi mudenga. Yayo yakanaka yekubatsira inopisa zvivakwa inoita kuti okisijeni yemvura ive yakakosha propellant muindasitiri yezvemuchadenga.

III. Kusiyana pakati peLiquid Nitrogen neLiquid Oxygen

Kunyangwe mashandisirwo enitrogen yemvura uye okisijeni yemvura achisiyana, ane misiyano yakakura mumasikirwo nemashandisirwo. Zvakananga:

1. Maumbirwo: Liquid nitrogen ine nitrogen gasi (N₂), nepo okisijeni yemvura ine okisijeni gasi (O₂).

2. Density: Liquid nitrogen deser pane liquid oxygen.

3. Boiling point: Liquid nitrogen ine pakadzikira pakufashaira pane liquid oxygen.

4. Kushandiswa: Liquid nitrogen inowanzoshandiswa kuomesa nekuchengetedza, nepo okisijeni yemvura ndiyo inonyanya kushandiswa seoxidant uye propellant. Chemical properties

Liquid nitrogen inert inert, ine yakagadzika mamorekuru chimiro chinoita kuti isaite machemical reactions nezvimwe zvinhu. Ichi chivakwa chinobvumira kuti chishandiswe segasi rekudzivirira uye kuiswa mune akawanda emakemikari nemaindasitiri maitiro. Kune rimwe divi, okisijeni yemvura ndeye yakasimba oxidizer ine yakakwira kemikari reactivity, uye inowanzoitika kune yakanyanya oxidation maitiro nezvimwe zvinhu, zvichiita kuti ishandiswe zvakanyanya mukupisa uye oxidation maitiro.

Tembiricha maitiro

Kuvira kwemvura yenitrogen yakadzikira pane yemvura yeokisijeni (mvura nitrogen -196°C, liquid oxygen -183°C), zvichiita kuti ikwane pakutonhodzwa nekuchengetedzwa patembiricha yakaderera. Kunyangwe okisijeni yemvura zvakare iri yekirasi yezvinwiwa zvecryogenic, kuita kwayo kuderera-tembiricha hakuna kunaka seyemvura nitrogen. Nokudaro, okisijeni yemvura ndiyo inonyanya kushandiswa kupisa uye oxidation pane kuchengetedza cryogenic. Safety

Liquid nitrogen haina kuchengetedzeka kushandisa nekuti haina kujaira kuita kemikari. Njodzi huru kukuvara kunotonhora kubva kune yakaderera tembiricha uye kutsiva okisijeni munzvimbo, izvo zvinogona kukonzera asphyxiation. Nepo okisijeni yemvura, seoxidizer, inofanirwa kuchengetedzwa kure nezvinhu zvinopfuta semafuta kudzivirira kupisa uye tsaona yekuputika. Nokudaro, zvinoda kuchenjerera zvakanyanya panguva yekushandiswa.

Liquid nitrogen uye liquid oxygen zvinwiwa zviviri zvakakosha zvekudzikira. Kunyangwe iwo ese ari maviri akagadzirwa kuburikidza nekuparadzaniswa kwemhepo, nekuda kweakasiyana makemikari uye emuviri zvimiro, minda yavo yekushandisa ine maonero akasiyana. Liquid nitrogen, ine inertness uye yakaderera-tembiricha maitiro, inoshandiswa zvakanyanya mukuchengetedza chando, kugadzira chikafu, uye kutonhora kwemaindasitiri, etc. Nepo okisijeni yemvura, ichitsamira pane yayo oxidizing maitiro, inonyanya kushandiswa pakupihwa kweokisijeni yekurapa, maindasitiri oxidation, uye aerospace propulsion, etc. Mukushanda kweaerospace, kushandiswa kweiyo nitrogen yemvura uye kutonhora kwemaindasitiri kunoda kuchengetedzwa kwakazara kweokisijeni yavo.

Isu tiri mugadziri uye mutengesi wemhepo yekuparadzanisa unit. Kana uchida kuziva zvakawanda nezvedu:
