Izindlela Zokukhiqiza I-Metallurgical Coke

I-coke ye-Metallurgical, ingxenye ebalulekile ekwenziweni kwensimbi, ikhiqizwa ngenqubo ebizwa ngokuthi i-coking. Le nqubo iguqula amalahle e-bituminous abe yikhabhoni ephezulu, izinto ezimbotshana ezinezakhiwo ezithile ezilungele iziko eliqhumayo. Lesi sihloko sihlola izindlela ezihlukahlukene ezisetshenziselwa ukukhiqiza i-coke ye-metallurgical, eqokomisa izinyathelo eziyinhloko nokucatshangelwa okuhilelekile kuleyo naleyo.

Inqubo Yokupheka Yendabuko: Ukusuka Elahleni Kuya Ku-Coke

Ukukhetha Amalahle Nokulungiselela

Uhambo oluya i-coke ye-metallurgical iqala ngokukhetha amalahle e-bituminous afanelekile. Akuwona wonke amalahle adalwa alingana; amalahle akhethiwe kufanele abe nezici ezithile, okuhlanganisa okuqukethwe okuphezulu okuguquguqukayo kanye nenkomba ye-caking efanele ukuqinisekisa ukwakheka okufanele kwe-coke. Ukulungiselela kuhlanganisa ukuhlanza amalahle ukuze kukhishwe ukungcola okufana nesibabule nomlotha, okungaba nomthelela omubi kwikhwalithi yomkhiqizo wokugcina. Le nqubo ngokuvamile ihlanganisa ukuchotshozwa, ukuhlola, nokuhlanganisa izinhlobo zamalahle ezihlukene ukuze kuzuzwe izakhiwo ezifiselekayo. Ukunaka lesi sigaba kubalulekile ekukhiqizeni izinga eliphezulu i-coke ye-metallurgical.

Ukushaja kanye nokupheka kuma-Coke Ovens

Amalahle alungisiwe ashajwa kuhhavini be-coke, emakamelweni amade, amancane ashiselwe ekushiseni okuphezulu kakhulu (okungaba ngu-1000°C). Inqubo yokushisisa, engathatha amahora angu-18-24, isusa izinto eziguquguqukayo emalahleni, ishiye insalela yekhabhoni eqinile: i-coke ye-metallurgical. Ohhavini ngokuvamile bakhiwa ngezitini eziphikisayo ukuze zimelane nokushisa okukhulu nokusabela kwamakhemikhali ngaphakathi. Inqubo yokupheka iphinde ikhiqize imikhiqizo etholakalayo efana negesi ye-coke oven, engasetshenziswa njengomthombo wamafutha. Ohhavini besimanje be-coke bavame ukufaka izinhlelo zokulawula ezithuthukile zokuqapha nokwenza kahle inqubo yokupheka, okuholela ekusebenzeni okuthuthukisiwe kanye nekhwalithi ye-coke.

Ukunciphisa nokulinganisa

Uma inqubo yokupheka isiqedile, ukushisa i-coke ye-metallurgical lucinywa—lupholiswe ngokushesha—ngokuvamile ngamanzi. Lesi sinyathelo sibalulekile ukuvimbela ukusha okuzenzakalelayo. Ngemva kokucisha, i-coke ilinganiswa ukuze ihlangabezane nezidingo ezithile zokusebenza kwesithando somlilo. Lokhu ngokuvamile kuhilela ukuchotshozwa nokuhlolwa ukuze uthole ukusabalalisa usayizi wezinhlayiyana oyifunayo. Izidingo zosayizi othize zingahluka kuye ngomklamo wesithando somlilo kanye nemingcele yokusebenza.

Alternative Coking Technologies

Ngenkathi ama-oven wendabuko e-coke ehlala eyindlela evelele i-coke ye-metallurgical ukukhiqizwa, kucutshungulwa ezinye izindlela zobuchwepheshe ukuze kuthuthukiswe ukusebenza kahle, kuncishiswe ukukhishwa kwezinto ezikhishwayo, futhi kusetshenziswe amalahle ekhwalithi ephansi. Lokhu kubandakanya:

Ifomu Coking

Ukupheka kwefomu kuhilela ukwelapha kusengaphambili amalahle abe yisimo esithile ngaphambi kokupheka, okuholela kumkhiqizo we-coke omfaniswano owengeziwe kanye nekhwalithi ephezulu. Lobu buchwepheshe buvumela ukulawula okungcono kwenqubo yokupheka, ukuthuthukisa isivuno jikelele kanye nezakhiwo ze-coke. Le ndlela inenzuzo ikakhulukazi uma usebenzisa amalahle anezakhiwo ze-caking ezifiselekayo kancane.

Amanye ama-Emerging Technologies

Ucwaningo nokuthuthukiswa kuyaqhubeka nokuhlola ubuchwepheshe obusha obuhlukahlukene okuhloswe ukuthuthuka i-coke ye-metallurgical ukukhiqizwa. Lokhu kuhlanganisa ukuhlola izindlela ezisebenzisa i-biomass noma imfucumfucu njenge-feedstock, enikeza ezinye izindlela ezisimeme emkhiqizweni ongokwesiko osuselwa kumalahle. Ukuthuthukiswa kwalobu buchwepheshe kuvame ukuthola uxhaso lukahulumeni nokubambisana kwezimboni, okuqhutshwa isidingo sokusimama kwemvelo kanye nokusetshenziswa kwezinsiza okuthuthukisiwe. Okunye kugxile ekwehliseni ukukhishwa kwekhabhoni nasekuthuthukiseni ukonga kwamandla.

Izakhiwo ze-Coke kanye Nokulawulwa Kwekhwalithi

Izinga le i-coke ye-metallurgical ihlolwa ngokusekelwe kumapharamitha ahlukahlukene, okuhlanganisa amandla ayo, i-porosity, i-reactivity, kanye nokuqukethwe kwesibabule. Lezi zakhiwo zinethonya ngokuqondile ukusebenza kwayo esithandweni somlilo, okunomthelela ekusebenzeni kahle kokukhiqizwa kwensimbi nensimbi. Izinyathelo eziqinile zokulawula ikhwalithi zisetshenziswa kuyo yonke inqubo yokukhiqiza ukuze kuqinisekiswe ikhwalithi ye-coke engaguquki, ehlangabezana nezidingo ezidingekayo zemboni yensimbi.

Ukuze uthole ulwazi olwengeziwe ngekhwalithi ephezulu ye-metallurgical coke, cabanga ukuthintana I-Inner Mongolia Xinxin Silicon Industry Co.,Ltd umkhiqizi ohamba phambili embonini.

¹ Idatha yezakhiwo ze-coke nokubaluleka kwazo ingatholakala ezincwadini ezihlukahlukene zobunjiniyela be-metallurgical kanye nokushicilelwe kwemboni. Idatha ethile izohluka kuye ngohlobo lwamalahle nenqubo yokupheka esetshenzisiwe.
