Iindlela zeMetallurgical Coke Production

Icoke ebizwa ngokuba yiMetallurgical coke, eyona nxalenye ibalulekileyo kwintsimbi nokwenza intsimbi, iveliswa ngenkqubo ebizwa ngokuba yicoking. Le nkqubo iguqula amalahle e-bituminous ibe yikhabhoni ephezulu, izinto ezirhabaxa ezineempawu ezithile ezifanelekileyo kwiziko lokuqhushumba. Eli nqaku liphonononga iindlela ezahlukeneyo ezisetyenziselwa ukuvelisa coke metallurgical, ibalaselisa amanyathelo aphambili neengcamango ezibandakanyekileyo kwisifundo ngasinye.

Inkqubo yokupheka yesiNtu: Ukusuka kwilahle ukuya kwi-Coke

Ukukhethwa kwamalahle kunye nokuLungisa

Uhambo oluya coke metallurgical iqala ngokukhetha amalahle ebhituminous afanelekileyo. Ayingawo onke amalahle adalwe alinganayo; amalahle akhethiweyo kufuneka abe neempawu ezithile, kubandakanywa umxholo ophezulu oguquguqukayo kunye nesalathisi esifanelekileyo se-caking ukuqinisekisa ukubunjwa okufanelekileyo kwe-coke. Ukulungiselela kubandakanya ukucoca amalahle ukususa ukungcola okufana nesalfure kunye nothuthu, ezinokuchaphazela kakubi umgangatho wemveliso yokugqibela. Le nkqubo ihlala ibandakanya ukutyunyuzwa, ukuhluzwa, kunye nokudibanisa iindidi zamalahle ezahlukeneyo ukufezekisa iipropati ezifunwayo. Ukuqwalaselwa ngenyameko kweli nqanaba kubaluleke kakhulu ekuveliseni umgangatho ophezulu coke metallurgical.

Ukutshaja kunye nokuphekwa kwiiOveni zeCoke

Amalahle asele elungisiwe agalelwa kwii-onti ze-coke, ezinde, kumagumbi amancinci afudunyezwe kumaqondo obushushu aphezulu kakhulu (malunga ne-1000°C). Inkqubo yokufudumeza, enokuhlala iiyure eziyi-18-24, igxotha izinto eziguqukayo kumalahle, ishiya ngasemva intsalela yekhabhoni eqinileyo: i coke metallurgical. Ii-oveni ngokwesiqhelo zakhiwa ngezitena ezikwaziyo ukumelana nobushushu obugqithisileyo kunye nokusabela kweekhemikhali ngaphakathi. Inkqubo yokupheka iphinda ivelise iimveliso ezivela kwi-oven gas ye-coke, enokusetyenziswa njengomthombo wamafutha. Ii-ovens ze-coke zanamhlanje zihlala zibandakanya iinkqubo zokulawula eziphambili zokubeka iliso kunye nokwandisa inkqubo yokupheka, ekhokelela ekuphuculeni ukusebenza kakuhle kunye nomgangatho we-coke.

Ukucima kunye nobukhulu

Emva kokuba inkqubo yokupheka igqityiwe, ishushu coke metallurgical lucinywa—lupholiswe ngokukhawuleza—ngokuqhelekileyo ngamanzi. Eli nyathelo libalulekile ukuthintela ukutsha okuzenzekelayo. Ukulandela ukucima, i-coke ilinganiswe ukuba ihlangabezane neemfuno ezithile zokusebenza kwesithando somlilo. Oku kubandakanya ukutyumza kunye nokuhlola ukufumana ukuhanjiswa kobungakanani besuntswana elifunekayo. Iimfuno zobukhulu obuthile zinokuhluka ngokuxhomekeke kuyilo lwesithando somlilo kunye neeparamitha zokusebenza.

IiTekhnoloji ezizezinye zokuCoka

Ngelixa ii-ovens ze-coke zemveli zihlala ziyiyona ndlela ibalaseleyo coke metallurgical imveliso, iindlela ezininzi zobuchwephesha ziyaphononongwa ukuphucula ukusebenza kakuhle, ukunciphisa ukukhutshwa kwezinto ezikhutshwayo, kunye nokusetyenziswa kwamalahle akumgangatho ophantsi. Ezi ziquka:

Ifomu Coking

Ukupheka ifom kubandakanya ukunyanga amalahle kwangaphambili kwimilo ethile ngaphambi kokupheka, okukhokelela kwimveliso efanayo kunye nekhwalithi ephezulu ye-coke. Le teknoloji ivumela ukulawula okungcono kwinkqubo yokupheka, ukuphucula isivuno esipheleleyo kunye neempawu ze-coke. Le ndlela inenzuzo ngokukhethekileyo xa usebenzisa amalahle aneempawu ezinqwenelekayo ze-caking.

Ezinye iiTekhnoloji ezisakhulayo

Uphando nophuhliso luyaqhubeka nokuphonononga iindlela ezahlukeneyo zobugcisa ezijolise ekuphuculeni coke metallurgical imveliso. Oku kubandakanya ukuphonononga iindlela ezisebenzisa i-biomass okanye inkunkuma yemathiriyeli njenge-feedstock, enikezela ngeendlela ezizinzileyo ngakumbi kwimveliso esekwe kumalahle emveli. Uphuhliso lobu bugcisa luhlala lufumana inkxaso-mali karhulumente kunye nentsebenziswano yoshishino, oluqhutywa yimfuno yozinzo lokusingqongileyo kunye nokusetyenziswa okuphuculweyo kobutyebi. Abanye bagxila ekunciphiseni ukukhutshwa kunye nokuphucula ukusebenza kakuhle kwamandla.

Iimpawu zeCoke kunye noLawulo loMgangatho

Umgangatho we coke metallurgical ivavanywa ngokusekelwe kwiiparamitha ezahlukeneyo, kubandakanywa amandla ayo, i-porosity, i-reactivity, kunye nomxholo wesulfure. Ezi zakhiwo zichaphazela ngokuthe ngqo ukusebenza kwayo kwisithando somlilo, esichaphazela ukusebenza kakuhle kwesinyithi kunye nemveliso yentsimbi. Amanyathelo okulawula umgangatho ongqongqo aphunyezwa kuyo yonke inkqubo yokuvelisa ukuqinisekisa umgangatho we-coke ongaguqukiyo, ukuhlangabezana neemfuno ezifunekayo kwishishini lensimbi.

Ngolwazi oluthe kratya malunga nekhwalithi ephezulu ye-metallurgical coke, cinga ngokuqhagamshelana I-Inner Mongolia i-Xinxin Silicon Industry Co.,Ltd umvelisi ohamba phambili kushishino.

¹ Idatha kwiipropati ze-coke kunye nokubaluleka kwazo kunokufumaneka kwiincwadi ezahlukeneyo zobunjineli be-metallurgical kunye nokupapashwa kweshishini. Idatha ethile iya kuhluka ngokuxhomekeke kuhlobo lwamalahle kunye nenkqubo yokupheka esetyenzisiweyo.
