Ndeapi minda yekushandisa yeokisijeni jenareta?

Pakangotanga nhanho yekutanga yekuvandudza tekinoroji yekugadzirwa kweokisijeni, huwandu hwemidziyo yemajenareta eokisijeni hwakanga hwakakura, uye chikumbaridzo chekushandisa cheokisijeni chaive chakakwira zvakanyanya.

Wnekuvandudzwa kwePSA okisijeni chizvarwa tekinoroji, zvakava nyore uye nyore kuwana nekushandisa oxygen.Maindasitiri mazhinji kana minda yatanga kuve neyawo okisijeni masisitimu,zvakadai,

 

1. Metallurgy

Muindasitiri yesimbi nesimbi, okisijeni kana mhepo yakawedzerwa neokisijeni inotumirwa kuchoto chekugadzira simbi kuburikidza nemhepo inoputika, iyo inogona kunyatso kuvandudza kubuda kwesimbi uye kuderedza kushandiswa kwesimba.

 

2. Mining uye mineral processing

Sechinyakare, mweya wakatsikirirwa unoshandiswa kuvandudza mwero wekutorwa kwezvigadzirwa zvemamineral.Sezvo kune chete 21% okisijeni mumhepo, iyo oxidation mhedzisiro inogumira.Kunyange zvazvo migodhi iyi iri munzvimbo dziri kure dzine zvinhu zvishoma zvekutakura zvinhu, vacheri vakawanda nemakambani emigodhi vanoshandisa PSA (pressure swing adsorption) tekinoroji yekugadzirwa kweokisijeni yekugovera okisijeni panzvimbo nekuda kwekushanda kwayo uye kuita kwakavimbika.

 

3.Kurapwa uye mukoti

Chipatara ichi chinorapa varwere vanenge vasina mweya wekufema nevarwere vari panjodzi.Imba inochengeterwa vakwegura inoshandisa okisijeni yekuyamwisa uye hutano, uye kudiwa kweokisijeni yekurapa kwemotokari dzekukurumidzira.

 

4.Indasitiri yemakemikari

Inogona kushandiswa kugadzira zvigadzirwa zvemakemikari, zvakadai semishonga, dhayi, zvinoputika, etc. Kutora kugadzirwa kweammonia yakagadzirwa semuenzaniso, okisijeni inogona kuita oxidize gasi rekudya kuti riwedzere kubuda kweammonia fertilizer.

 

5.Michina indasitiri

Okisijeni inogona kushandiswa seyamuro yekupisa yakabatana neacetylene, propane uye mamwe magasi anopisa, anogona kuburitsa tembiricha inodarika 3000 ° C uye kuita basa rekutambisa nekucheka simbi.

 

6.Aquaculture

Nekuwedzera huwandu hweokisijeni mudziva rehove, hove dzinogona kudya zvakanyanya uye kukura nekukurumidza.

 

8. Furnace combustion support

Kupisa kwechoto kunotsigira kunowanzo kunzi oxygen inopfumisa kupisa.Oxygen enriched combustion imhando yemhando yepamusoro-yepamusoro-inochengetedza simba-inopisa tekinoroji, umo ine okisijeni-ine gasi ine okisijeni inokwira kupfuura iyo yemhepo (20.947%).Simba rekuchengetedza simba rinoshamisa, hupenyu hwevira hunobudirira hurefu, kunyunguduka kunovandudzwa, nguva yekupisa inopfupiswa, uye kubuda kunowedzera;Chiyero chakakanganisika chinoderedzwa uye chiyero chakapedzwa chechigadzirwa chinovandudzwa.Iyo yekuchengetedzwa kwemamiriro ekunze yakatanhamara.

 

9. Metal welding nekucheka

Muwelding, okisijeni inogona kuita kuti mafuta awedzere kutsva, tembiricha yakakwira, uye welding inokurumidza uye zvirinani.Mukucheka oxyfuel, torch chubhu inoshandiswa kupisa simbi kusvika pakupisa kwayo.Zvadaro, mukova weokisijeni gasi unobaiwa pasimbi kuti uipise musimbi okisidhi, inoyerera ichibuda kubva pakatsemuka muchimiro che slag.

 

10. Fermentation process

Mune aerobic yakadzika tsika, kupihwa kweokisijeni kunogara kuri chimwe chezvinhu zvakakosha zvinomisa zvekubudirira kwekuvirisa.Iyo yakagadziridzwa mhepo inoshanda inoderedza huwandu hwemhepo inoshandiswa uye inowedzera kuderedza mukana wekuumbwa kwefuro kana kusvibiswa kwebhakitiriya.
