I-HANGZHOU NUZHUO TECHNOLOGY GROUP CO., LTD.

I-Liquid oxygen iwuketshezi oluluhlaza okwesibhakabhaka oluphaphathekile emazingeni okushisa aphansi, olunomthamo omkhulu kanye nezinga lokushisa eliphansi kakhulu. Indawo abilayo yomoya-mpilo owuketshezi ngu -183℃, okwenza izinze ezindaweni ezinethempelesha eliphansi uma kuqhathaniswa nomoya-mpilo wegesi. Ngokwesimo esiwuketshezi, ukuminyana komoyampilo cishe ku-1.14 g/cm³, okwenza umoya-mpilo owuketshezi ube lula ukuwugcina nokuthutha kunomoya-mpilo wegesi. I-oksijini yoketshezi ayigcini nje ngokuba ne-oksijeni ephezulu kodwa futhi inezindawo eziqinile ze-oxidizing, ezikwazi ukusabela ngokushesha ngezinto eziningi eziphilayo.

Isici sezinga lokushisa eliphansi le-oksijini ewuketshezi sidinga okokusebenza okukhethekile kanye nezilinganiso ngesikhathi sokugcinwa nokuthuthwa, njengokusebenzisa iziqukathi ezifakwe izinga lokushisa eliphansi ukuze kuvinjelwe ukudluliswa kokushisa. Ayinaphunga futhi ayinambala, kodwa ngenxa yokushisa kwayo okuphansi kakhulu, umoya-mpilo owuketshezi ungase ubangele isithwathwa nezinye izingozi emzimbeni womuntu, ngakho ukunakekelwa okukhethekile kuyadingeka ngesikhathi sokusebenza.

Ukukhiqizwa kanye nenqubo yokukhiqiza ye-oxygen ewuketshezi

Ukukhiqizwa komoya-mpilo owuketshezi kuvame ukusebenzisa ubuchwepheshe obujulile bokuhlukanisa umoya we-cryogenic, okuyindlela yokuhlukanisa izingxenye zomoya ngokusebenzisa ukupholisa okuphansi kwezinga lokushisa nokucindezelwa okuphumelelayo. Isimiso esiyisisekelo sokuhlukaniswa komoya okujulile kwe-cryogenic ukuhlukanisa izingxenye ezihlukahlukene zomoya ngokusekelwe kumaphuzu azo ahlukene abilayo. Okokuqala, umoya uyacindezelwa, bese kuthi ngezigaba eziningi zokunwetshwa nokupholisa, umoya kancane kancane ufinyelele izinga lokushisa eliphansi kakhulu, futhi ekugcineni umoya-mpilo uyahlukaniswa nomoya futhi ufakwe uketshezi. Ukukhiqizwa komoya-mpilo owuketshezi kudinga amasistimu okupholisa asebenza kahle kanye nemishini yokuhlanza ukuze kuqinisekiswe ukuhlanzeka nokuzinza komoyampilo owuketshezi.

Ubuchwepheshe bokuhlukaniswa komoya obujulile be-cryogenic abukwazi nje ukukhiqiza umoya-mpilo owuketshezi kodwa futhi ngesikhathi esifanayo bathole amanye amagesi angamazinga okushisa aphansi njenge-nitrogen ewuketshezi kanye ne-argon ye-liquid. Le mikhiqizo iphinde ibe nokusetshenziswa okubanzi embonini. Ukuhlanzeka okuphezulu nezici zokushisa eziphansi ze-oksijini ye-liquid kwenza kube okubalulekile ezinhlelweni eziningi ezikhethekile zezimboni.

Izinkambu eziyinhloko zesicelo se-oxygen ye-liquid

I-oxygen ewuketshezi isetshenziswa kabanzi emikhakheni eminingi yezimboni. Okokuqala, endimeni ye-aerospace, i-oxygen ewuketshezi ingenye ye-rocket oxidants evame ukusetshenziswa, njengoba inokuqukethwe okuphezulu komoyampilo kanye nekhono lokusiza ukusha, elingasabela ngophethiloli ngokushesha ukuze kukhiqizwe inani elikhulu lamandla ukuze kuqhutshwe amarokhethi. Inhlanganisela yomoya-mpilo owuketshezi kanye ne-hydrogen ewuketshezi ibizwa ngesinye seziphehli zamarokhethi ezivame kakhulu, futhi ukusunduza kwayo okunamandla nokusebenza okuhle kakhulu kuyenza ithandeke kakhulu kubuchwepheshe be-aerospace.

Okwesibili, emkhakheni wezokwelapha, umoya-mpilo owuketshezi usetshenziswa njengomthombo obalulekile womoya-mpilo. Umoya-mpilo owuketshezi ugcinwa emazingeni okushisa aphansi bese uhwamuka ukuze usetshenziswe njengomoya-mpilo wezokwelapha, kusiza iziguli ezinobunzima bokuphefumula zithole umoya-mpilo owanele. Ngaphezu kwalokho, i-oksijeni ye-liquid idlala indima ebalulekile ku-metallurgy, ubunjiniyela bamakhemikhali, nakweminye imikhakha, ikakhulukazi emazingeni okushisa aphezulu kanye nezinqubo ze-chemical synthesis, lapho ikhono layo eliqinile le-oxidizing lisetshenziswa kabanzi.

Izinyathelo zokuphepha zomoya-mpilo owuketshezi

Nakuba umoya-mpilo owuketshezi unemisebenzi ebanzi, ngenxa yokuphinda usebenze kabusha kwawo okuphezulu nezici zezinga lokushisa eliphansi, kunezingozi ezithile zokuphepha. Okokuqala, i-oxygen ye-liquid iyi-oxidant enamandla, engasheshisa inqubo yokuvutha, ngakho-ke kufanele igwenywe ukuthintana nezinto ezivuthayo ngesikhathi sokugcina nokusebenzisa. Ngesikhathi esifanayo, izinga lokushisa eliphansi kakhulu lomoya-mpilo owuketshezi lingase libangele isithwathwa, ngakho-ke izinto zokuzivikela ezifanele njengamagilavu ​​ukumelana nokubanda namamaski kufanele zigqokwe ngesikhathi sokuhlinzwa komoyampilo owuketshezi ukuze kugwenywe ukulimala kwesikhumba namehlo.

Ukugcinwa komoyampilo owuketshezi kudinga iziqukathi ezikhethekile eziklanyelwe izinga lokushisa eliphansi, ngokuvamile ezinezici ezinhle zokuvikela ukuvimbela ukushisa kwangaphandle ukuthi kungangeni futhi kubangele izinga lokushisa lomoya-mpilo owuketshezi likhuphuke. Ukwengeza, ngesikhathi senqubo ye-vaporization ye-oxygen ye-liquid, izokhula ngokushesha futhi ikhiqize inani elikhulu le-oksijeni, okungase kuholele ekwandeni kokuhlushwa komoya-mpilo emvelweni, okwandisa ingozi yomlilo. Ngakho-ke, ngesikhathi sokugcinwa kanye nokuthuthwa kwe-oksijini ewuketshezi, imithethonqubo yokuphepha efanele kufanele ilandelwe ngokuqinile ukuze kuqinisekiswe indawo ephephile yokusebenza kanye nokuhlala komoya.

Ukuqhathanisa umoya-mpilo owuketshezi namanye amagesi ezimboni

I-oxygen ewuketshezi, njenge-nitrogen eyi-liquid ne-argon eyi-liquid, yabelana ngezici ezithile zomzimba ezifanayo, kodwa kunomehluko omkhulu ekusetshenzisweni nasezimpahleni. Iphoyinti lokubilisa le-nitrogen ewuketshezi ngu--196℃, ephansi kunaleyo ye-oksijini ewuketshezi, ngakho-ke i-nitrogen ewuketshezi ivamise ukusetshenziswa njengesipholisa, kuyilapho i-oxygen ewuketshezi, ngenxa yezakhiwo zayo eziqinile ze-oxidizing, ivamise ukusetshenziswa njengesilekeleli sokuvutha noma i-oxidant. Ngaphezu kwalokho, i-argon ye-liquid, njengegesi ye-inert, ayijwayele ukusabela nezinye izinto ngesikhathi sokuphendula kwamakhemikhali futhi isetshenziselwa ukuvikela umkhathi. Nakuba i-oxygen ewuketshezi, ngenxa yokuphinda isebenze kabusha, ivame ukusetshenziswa ekuhlanganiseni kwamakhemikhali nasezinqubweni zokuvutha.

Phakathi kwala magesi ezimboni, umoya-mpilo owuketshezi uhlukile ngenxa yesakhiwo sawo esiqinile se-oxidizing, ikakhulukazi ezimeni ezidinga ukushiswa okuphumelelayo nokusabela kwe-oxidation okukhulu. Izici zamagesi ezimboni ahlukene zibenza bakwazi ukudlala indima ebalulekile emikhakheni ehlukene yokusetshenziswa kwabo.

Ubungane bemvelo kanye nokusimama kwe-oxygen ye-liquid

Nakuba umoya-mpilo owuketshezi, njengegesi yezimboni, unokuphinda usebenze kabusha okuphakeme uma kuqhathaniswa, awukubangeli ukungcoliswa kwemvelo empeleni. Umoya-mpilo, njengengxenye ebalulekile yomkhathi, imikhiqizo yawo yokugcina enqubweni yokusabela ngokuvamile iyizinto ezingenabungozi njengamanzi noma isikhutha. Kodwa-ke, inqubo yokukhiqiza umoya-mpilo owuketshezi idinga inani elikhulu lamandla, ikakhulukazi enqubweni yokuhlukanisa ukupholisa okujulile, ngakho-ke ukwenza ngcono ukusebenza kahle kwamandla okukhiqizwa komoya-mpilo owuketshezi kubaluleke kakhulu ekuvikelweni kwemvelo.

Ngokusebenzisa imishini esebenza kahle kakhulu kanye nokwenza ngcono ukugeleza kwenqubo, kungenzeka ukunciphisa ukusetshenziswa kwamandla ngenkathi kunciphisa umthelela wemvelo wokukhiqizwa komoya-mpilo owuketshezi. Ngokuthuthukiswa kobuchwepheshe bamandla aluhlaza, ukukhiqizwa komoya-mpilo owuketshezi kulindeleke ukuthi kube nobungane ngokwemvelo futhi kusimame esikhathini esizayo, kuhlinzeke ngomthombo ohlanzekile womoya-mpilo wokukhiqizwa kwezimboni nokuphila komuntu. Isiphetho

I-oksijini yoketshezi, njengendlela yoketshezi lomoya-mpilo, isetshenziswe kabanzi ezimbonini, emkhathini, nasekunakekelweni kwezempilo ngenxa yezakhiwo zayo ezihlukile zomzimba kanye nemvelo eqinile yokwenza i-oxidizing. Nakuba ukukhiqizwa nokusetshenziswa komoyampilo owuketshezi kudinga izinyathelo zokuphepha eziqinile, indima yawo ebalulekile emikhakheni eminingi ayinakushintshwa. Ngokuzayo, ngokuthuthuka okuqhubekayo kobuchwepheshe, ukukhiqizwa nokusebenzisa umoya-mpilo owuketshezi kulindeleke ukuthi kusebenze kahle futhi kuhambisane nemvelo, ngaleyo ndlela kuhlangatshezwane nezidingo zomphakathi kangcono.

Singabakhiqizi nabathekelisi beyunithi yokuhlukanisa umoya. Uma ufuna ukwazi okwengeziwe ngathi:
