I-nitrogen ewuketshezi, enefomula yamakhemikhali i-N₂, iwuketshezi olungenambala, olungenaphunga, nolungenabo ubuthi olutholakala ngokucwilisa i-nitrogen ngenqubo yokupholisa okujulile. Isetshenziswa kabanzi ocwaningweni lwesayensi, kwezokwelapha, embonini, nasekuqandeni ukudla ngenxa yokushisa kwayo okuphansi kakhulu kanye nezicelo ezihlukahlukene. Ngakho-ke, i-nitrogen ewuketshezi yakhiwa kanjani? Lesi sihloko sizonikeza impendulo eningiliziwe yalo mbuzo kusuka ezicini eziningana: ukukhishwa kwe-nitrogen, indlela yokuhlukanisa umoya opholile ngokujulile, inqubo yokukhiqizwa kwe-nitrogen ewuketshezi, kanye nezicelo zayo ezingokoqobo.

Ukukhishwa kwe-nitrogen

Ukukhiqizwa kwe-nitrogen ewuketshezi kudinga isinyathelo sokuqala sokuthola i-nitrogen emsulwa. I-nitrogen iyisakhi esiyinhloko somkhathi woMhlaba, esibalelwa ku-78% womthamo womoya. Ukukhipha i-nitrogen kuvame ukwenziwa kusetshenziswa ubuchwepheshe bokuhlukaniswa komoya obandayo noma izindlela zokudonswa kwe-pressure swing (PSA). Ukuhlukaniswa komoya obandayo ojulile kuyindlela yezimboni esetshenziswa kakhulu. Ngokucindezela nokupholisa umoya, kuhlukanisa umoya-mpilo, i-nitrogen, nezinye izingxenye zegesi emazingeni okushisa ahlukene. Indlela yokudonswa kwe-pressure swing isebenzisa izakhiwo ezahlukene zokudonswa kwe-adsorbents zamagesi ahlukene, okufeza i-nitrogen emsulwa kakhulu ngomjikelezo wokudonswa kwe-adsorption kanye nokudonswa kwe-desorption. Lezi zindlela ziqinisekisa ubumsulwa kanye nekhwalithi ye-nitrogen njengezinto zokusetshenziswa zenqubo yokukhiqiza i-nitrogen ewuketshezi.

Indlela yokuhlukanisa umoya obandayo ojulile

Indlela yokuhlukanisa umoya obandayo ojulile ingenye yezinyathelo ezibalulekile ekukhiqizweni kwe-nitrogen ewuketshezi. Le ndlela isebenzisa amaphuzu abilayo ahlukene amagesi emoyeni ukuze i-nitrogen, i-oxygen, nezinye izingxenye zegesi zincibilike futhi ziqhume kancane kancane. Indawo yokubilisa ye-nitrogen ingu-195.8℃, kanti eye-oxygen ingu-183℃. Ngokwehlisa izinga lokushisa kancane kancane, i-oxygen iyancibilika kuqala bese ihlukaniswa namanye amagesi, kushiye ingxenye esele ibe yi-nitrogen emsulwa kakhulu. Ngemva kwalokho, le nitrogen ipholiswa ngaphansi kwendawo yayo yokubilisa ukuze incibilike ibe yi-nitrogen ewuketshezi, okuyisimiso esiyinhloko sokwakheka kwe-nitrogen ewuketshezi.

Inqubo yokukhiqizwa kwe-nitrogen ewuketshezi

Inqubo yokukhiqiza i-nitrogen ewuketshezi ihilela izinyathelo eziningana eziyinhloko: Okokuqala, umoya uyacindezelwa futhi uhlanzwe ukuze kususwe ukungcola okufana namanzi ne-carbon dioxide; bese kuba umoya opholile kusengaphambili, ngokuvamile ube cishe ku--100℃ ukuthuthukisa ukusebenza kahle kokuhlukanisa; okulandelayo, kwenziwa ukuhlukaniswa okubandayo okujulile, kupholiswa kancane kancane igesi ibe yizinga lokushisa loketshezi lwe-nitrogen ukuze kutholakale igesi ye-nitrogen ewuketshezi. Kule nqubo, ama-heat exchanger kanye nemibhoshongo yokuhlukaniswa idlala indima ebalulekile ekuqinisekiseni ukuhlukaniswa okuphumelelayo kwezingxenye ezahlukene emazingeni okushisa afanele. Okokugcina, igesi ye-nitrogen ewuketshezi igcinwa ezitsheni ezifakwe umswakama eziklanywe ngokukhethekile ukuze kugcinwe izinga lokushisa layo eliphansi kakhulu futhi kuvinjelwe ukulahleka komswakama.

Izinselele zobuchwepheshe ekwakhekeni kwe-nitrogen ewuketshezi

Ukwakheka kwe-nitrogen ewuketshezi kudinga ukunqoba izinselele eziningana zobuchwepheshe. Okokuqala ukugcinwa kwendawo ephansi yokushisa, njengoba izinga lokubila le-nitrogen ewuketshezi liphansi kakhulu. Ngesikhathi senqubo yokuncibilikisa uketshezi, kuyadingeka ukugcina izinga lokushisa lingaphansi kuka-195.8℃, okudinga imishini yokuqandisa esebenza kahle kanye nezinto zokuvikela. Okwesibili, ngesikhathi senqubo yokubanda okujulile, ukuminyana ngokweqile komoya-mpilo kumele kugwenywe ngoba umoya-mpilo owuketshezi unezakhiwo ezinamandla zokuncibilikisa futhi ubeka izingozi zokuphepha ezingaba khona. Ngakho-ke, ngesikhathi senqubo yokuklama, inqubo yokuhlukanisa i-nitrogen-oxygen kumele ilawulwe ngokunembile, futhi izinto ezifanele kumele zisetshenziswe ukuqinisekisa ukuphepha nokuzinza kwesistimu. Ngaphezu kwalokho, ukuthuthwa nokugcinwa kwe-nitrogen ewuketshezi kudinga ama-flask e-Dewar aklanywe ngokukhethekile ukuvimbela ukunyuka kwezinga lokushisa kanye nokulahleka kokuhwamuka kwe-nitrogen ewuketshezi.

Ukusetshenziswa kwangempela kwe-nitrogen ewuketshezi

Izakhiwo ze-nitrogen ewuketshezi ezisezingeni eliphansi ziyenza isebenze kabanzi emikhakheni eyahlukahlukene. Kwezokwelapha, i-nitrogen ewuketshezi isetshenziswa ekuhlinzeni izicubu kanye nokulondolozwa kwezicubu, njengokuqandisa izilonda zesikhumba kanye nokugcina amasampula ezinto eziphilayo. Embonini yokudla, i-nitrogen ewuketshezi isetshenziselwa ukuqandisa ukudla ngokushesha, njengoba indawo yayo esezingeni eliphansi kakhulu ingaqandisa ukudla ngokushesha, inciphise umonakalo esakhiweni samaseli futhi ngaleyo ndlela igcine ukunambitheka kokuqala kanye nokudla okunomsoco kokudla. Ensimini yocwaningo, i-nitrogen ewuketshezi isetshenziswa kabanzi ocwaningweni lwe-superconductivity, ukuhlolwa kwe-physics esezingeni eliphansi, njll., okuhlinzeka ngendawo yokuhlola esezingeni eliphansi kakhulu. Ngaphezu kwalokho, ekukhiqizweni kwezimboni, i-nitrogen ewuketshezi isetshenziswa ekucubungulweni kwensimbi, ekwelashweni kokushisa, kanye nanjengegesi engasebenzi ukuvimbela ukusabela okuthile kwamakhemikhali ukuthi kwenzeke. Isiphetho

Inqubo yokwakheka kwe-nitrogen ewuketshezi iyinqubo eyinkimbinkimbi ebonakalayo, etholakala kakhulu ngezindlela zokuhlukanisa umoya obandayo ojulile kanye nobuchwepheshe bokuncibilikisa uketshezi. Impahla ephansi ye-nitrogen ewuketshezi yenza idlale indima ebalulekile emikhakheni ehlukahlukene njengemboni, ezokwelapha, kanye nocwaningo. Kusukela ekukhishweni kwegesi ye-nitrogen kuya ekuncibilikiseni uketshezi olubandayo ojulile futhi ekugcineni kuya ekusetshenzisweni kwayo, isinyathelo ngasinye sibonisa amandla obuchwepheshe obuphambili bokuqandisa nokuhlukanisa. Emisebenzini engokoqobo, ochwepheshe badinga futhi ukuthuthukisa inqubo yokukhiqiza njalo ukuze banciphise ukusetshenziswa kwamandla futhi bathuthukise ukusebenza kahle kokukhiqizwa kwe-nitrogen ewuketshezi.

Singabakhiqizi kanye nabathumeli beyunithi yokuhlukanisa umoya. Uma ufuna ukwazi kabanzi ngathi:
