Tlhahiso ea Metallurgical Coke: Tataiso e Feletseng

Tataiso ena e fana ka kakaretso e qaqileng ea tlhahiso ea coke metallurgical, e koahelang ts'ebetso, lisebelisoa tsa bohlokoa, taolo ea boleng, le maikutlo a tikoloho. Ithute ka lisebelisoa tse tala, mekhoa ea tlhahiso, le karolo ea bohlokoa eo coke e e bapalang ho etseng tšepe le ho etsa tšepe. Hape re tla hlahloba mekhoa le liphephetso tse tobaneng le indasteri ena ea bohlokoa.

Mokhoa oa ho etsa Cokemaking: Ho tloha Leshala ho ea ho Coke

Khetho ea Lintho tse tala le Tokisetso

The tlhahiso ea coke metallurgical e qala ka khetho ea mashala a loketseng a ho pheha. Mashala ana a na le thepa e ikhethang, ho kenyeletsoa litaba tsa ona tse feto-fetohang, index ea caking, le litaba tsa molora, tse amang boleng ba sehlahisoa sa ho qetela. Ho kopanya ka hloko ha mefuta e fapaneng ea mashala hangata hoa hlokahala ho fihlela thepa ea coke e lakatsehang. Tokisetso e kenyelletsa ho pshatla, ho hlahlobisisa, le ho kopanya ho netefatsa hore lijo li lula li le teng bakeng sa lionto tsa coke.

Ts'ebetso ea Oven ea Coke

Leshala le kopantsoeng le tšeloa ka har'a lionto tsa coke, e leng likamore tse telele, tse tšesaane tse futhumatsang mocheso o phahameng. Leshala le na le carbonization, e leng mokhoa o lelekang ntho e sa tsitsang, e siea ka morao masala a porous, a thata a carbon - coke metallurgical. Li-ovine tsa sejoale-joale tsa coke hangata li kenyelletsa mahlale a tsoetseng pele bakeng sa phetisetso e nepahetseng ea mocheso le taolo ea ts'ebetso ea carbonization. Ts'ebetso hangata e nka lihora tse 18-24, ho latela moralo oa onto le maemo a ts'ebetso. Joale coke e hlahisoang e tingoa ka metsi ho e pholisa le ho thibela liphetoho tse ling.

Coke Quenching le Screening

Ka mor'a carbonization, coke e chesang e tima ho e pholile ka potlako, hangata e sebelisa metsi kapa mekhoa e omileng ea ho tima. Ho tima ho omisa ho baballa tikoloho, ho fokotsa tšilafalo ea metsi le ho fana ka melemo ea ho khutlisa matla. Ka mor'a ho tima, coke e hlahlojoa ho tlosa likotlo le likotoana tse kholo ho feta tekano, ho netefatsa boholo bo tsitsitseng ba sehlahisoa bakeng sa ho sebelisoa libōping tsa mollo. Sehlahisoa sa ho qetela, coke ea metallurgical, ke karolo ea bohlokoa tlhahisong ea tšepe le tšepe.

Taolo ea Boleng le Litlhaloso

Boleng ba coke ea metallurgic ke ea bohlokoa bakeng sa ho etsa tšepe hantle. Thepa ea bohlokoa e kenyelletsa: M10, M25, li-indices tsa matla a M40; khanyetso ea abrasion; reactivity; le dikahare tsa molora. Mehato e tiileng ea taolo ea boleng e sebelisoa hohle tlhahiso ea coke metallurgical ho etsa bonnete ba boleng bo tsitsitseng ba sehlahisoa le ho fihlela litlhoko tse khethehileng tsa mabili a tšepe. Ho etsoa tlhahlobo le tlhahlobo ea kamehla ho lekola thepa ena.

Mehopolo ea Tikoloho Tlhahisong ea Coke

The tlhahiso ea coke metallurgical e na le litlamorao tsa tikoloho, haholo-holo tse amanang le mesi ea moea (joalo ka benzene, toluene, xylene, le particulate matter) le ho lahla litšila. Limela tsa sejoale-joale tsa coke li sebelisa mahlale a fapaneng a taolo ea tšilafalo, ho kenyeletsoa lits'ebetso tsa ho hloekisa khase le ho tima ho omella ho fokotsa tšusumetso ea tikoloho. Mekhoa ea moshoelella, joalo ka ntlafatso ea ts'ebeliso ea matla a matla le ts'ebetso ea litšila, le tsona li ntse li amoheloa ka ho fetesisa. Liphuputso tse ling le nts'etsopele li tsepamisitsoe mekhoeng ea tlhahiso ea li-coke e seng kotsi tikolohong.

Mekhoa le Mathata a Kamoso

Bokamoso ba indasteri ea coke ea metallurgic e tobane le liqholotso tse 'maloa, ho kenyelletsa le ho eketseha ha melao ea tikoloho, litheko tse feto-fetohang tsa mashala, le tlhoko ea ntlafatso e tsoelang pele ea ts'ebetso ea matla le ts'ebetso e tsitsitseng. Boiteko ba lipatlisiso le nts'etsopele bo tsepamisitse maikutlo ho ntlafatseng boleng ba coke, ho fokotsa mesi, le ho lekola mekhoa e meng ea ho etsa cokemaking, e ka kenyelletsang tšebeliso ea biomass kapa lijo tse ling tse tšoarellang. Indasteri e sebetsa ho netefatsa phepelo e tsoelang pele ea thepa ena ea bohlokoa bakeng sa tlhahiso ea tšepe le tšepe ha e ntse e fokotsa sebaka sa eona sa tikoloho.
