Ukupheka Amalahle Ekwenziweni Kwensimbi: Umhlahlandlela Ophelele

Lesi sihloko sihlola indima ebalulekile ye ukupheka amalahle ekwenzeni insimbi, ichaza izici zayo, inqubo yokwenza insimbi, ukucatshangelwa kwemvelo, kanye nezitayela zesikhathi esizayo. Sihlolisisa ukusabela kwamakhemikhali, izinselelo imboni ebhekene nazo, kanye nezixazululo ezingaba khona zekusasa elisimeme ekukhiqizeni insimbi.

Ukuqonda Iqhaza Lokupheka Amalahle

Ukupheka amalahle iwumshini wamalahle ensimbi akhethwe ngokukhethekile ngenxa yekhono lawo lokukhiqiza i-coke, uphethiloli onezimbotshana obalulekile enqubweni yesithando somlilo sokwenziwa kwensimbi. Ngokungafani nezinye izinhlobo zamalahle, amalahle okuphekela anezinto eziyingqayizivele ezenza alungele le njongo. Lezi zakhiwo zihlanganisa okuqukethwe okuphezulu kwe-volatile, okuqukethwe kwesibabule esincane, kanye nohlu oluthile lokuqukethwe komlotha. Okuqukethwe okuphezulu kwento eguquguqukayo kubalulekile ekukhiqizeni isakhiwo se-coke esiqinile futhi esinezimbobo, esidingekayo ukuze kuncishiswe insimbi yensimbi esebenza ngempumelelo esithandweni somlilo. Okuqukethwe kwesibabule esiphansi kubalulekile ukuze kuncishiswe ukungcoliswa kwesibabule ensimbi ewumphumela, kugcinwe ikhwalithi yayo kanye nezinto ezifiswayo.

Izici Zokupheka Amalahle

Izakhiwo eziningana ezibalulekile zihlukanisa amalahle okupheka kwamanye amalahle. Lokhu kufaka phakathi okuqukethwe kwayo kwekhabhoni ephezulu, uhla lwento ethile eguquguqukayo, kanye nomlotha ophansi nesibabule. Ububanzi obunembile balezi zakhiwo buyahlukahluka kuye ngekhwalithi ye-coke efunwayo kanye nenqubo ethile yokwenza insimbi. Izici ze- ukupheka amalahle ithonya ngokuqondile ikhwalithi ye-coke ekhiqiziwe, ebuye ibe nomthelela ekusebenzeni kahle nokukhishwa kwenqubo yokwenza insimbi. Ukukhethwa kwe ukupheka amalahle kuyisinyathelo esibalulekile ekuqinisekiseni ukukhiqizwa kwensimbi yezinga eliphezulu. Abahlinzeki, njengaye I-Inner Mongolia Xinxin Silicon Industry Co.,Ltd, zihlole ngokucophelela lezi zakhiwo ukuze zihlangabezane nezidingo zamakhasimende.

Inqubo yokwenza insimbi kanye namalahle okuphekela

Inqubo yokwenza insimbi ihlanganisa izinyathelo ezimbalwa, kanti isithando somlilo esiqhumayo siyisiteji esimaphakathi lapho ukupheka amalahle idlala indima ebalulekile. Esithandweni somlilo, i-coke isebenza njengophethiloli kanye ne-ejenti yokunciphisa. Inikeza ukushisa okudingekayo ukuze kuncibilike insimbi futhi yehlise ama-iron oxides abe yinsimbi eyinsimbi. Isakhiwo se-porous se-coke siqinisekisa ukugeleza kwegesi okuphumelelayo nokusabalalisa ukushisa ngaphakathi kwesithando somlilo. Umsebenzi we-blast furnace udla amandla ngendlela emangalisayo, okwenza ukusebenza kahle kwe- ukupheka amalahle ukukhathazeka okuyinhloko kubakhiqizi bensimbi.

Ukusabela kweBlast Furnace

Ukusabela kwamakhemikhali ngaphakathi kwesithando somlilo kuyinkimbinkimbi futhi kuhilela ukuncishiswa kwama-iron oxides (Fe2O3 kanye ne-Fe3O4) abe yinsimbi eyinsimbi (Fe) kusetshenziswa i-carbon monoxide (CO) ekhiqizwa ekushisweni kwe-coke. Le nqubo incike kakhulu kumazinga okushisa, idinga ukushisa okuphezulu okukhiqizwa ukushiswa kwe-coke. Izinga le-coke lithinta ngqo izinga nokusebenza kahle kwenqubo yokunciphisa kanye nekhwalithi yensimbi ephumela. Ukuze usebenze kahle, kufanele kucatshangelwe ngokucophelela ekukhetheni nasekuxutshweni kwezinhlobo ezihlukene ze ukupheka amalahle ukufeza izakhiwo ze-coke ezifunayo.

Ukucatshangelwa Kwemvelo Nokusimama

Imboni yensimbi inomlando obalulekile wemvelo, nge ukupheka amalahle ukushiswa okunomthelela ekukhishweni kwesisi esibamba ukushisa. Imboni izama ngenkuthalo ukunciphisa umthelela wayo kwezemvelo ngamasu ahlukahlukene, okuhlanganisa nokwenza kahle ukusebenza kwesithando somlilo esiqhumayo, ukuthuthukiswa kwezinye izinto zokubasa, kanye nokusetshenziswa kobuchwepheshe bokubanjwa kanye nokugcinwa kwekhabhoni. Ucwaningo luyaqhubeka kwezinye izindlela zobuchwepheshe zokukhiqiza insimbi nensimbi, njengezinqubo ezisekelwe ku-hydrogen, ukuze kuncishiswe ukuthembela kumafutha ezinto ezimbiwa phansi njenge ukupheka amalahle. Le ntuthuko ibalulekile ekuqinisekiseni ikusasa elisimeme lokwenziwa kwensimbi.

Amathrendi Azayo Ekuphekeni Amalahle Nokwenza Insimbi

Ikusasa lokwenza insimbi kungenzeka libandakanye ukushintshela ezinqubweni ezisimeme kakhulu nezinobungani nemvelo. Lokhu kubandakanya ukugxila okukhulu ekuthuthukisweni kokusebenza kahle ngaphakathi kobuchwepheshe obukhona, ukuhlola amanye ama-ejenti anciphisayo ukuze kuncishiswe ukuthembela ukupheka amalahle, kanye nokuthuthukisa izindlela ezintsha zokwenza insimbi ezinomthelela omncane kwezemvelo. Ukuhlolwa kwamanye amafutha kanye nezinqubo kubalulekile ekufezeni lezi zinhloso. Lokhu kuhlanganisa uphenyo kanye nokuqaliswa kobuchwepheshe bokubanjwa kwekhabhoni, okuhloswe ngayo ukunciphisa kakhulu izinga lekhabhoni lokukhiqizwa kwensimbi.

Qaphela: Lobu bubanzi busondele futhi bungahluka kuye ngomthombo othile wamalahle kanye nezidingo zekhwalithi.

Lolu lwazi olwezinjongo zolwazi olujwayelekile kuphela. Hlala uthintana nochwepheshe bemboni abafanelekile kanye nemithombo esemthethweni yezicelo ezithile kanye nezinyathelo zokuphepha.
