Izixhobo eziphambili zokwenza i-graphitized petroleum coke yi-continuous graphitization furnace. Iingenelo zayo zobuchwepheshe kunye neempawu zenkqubo zenze ukuba ibe lukhetho oluphambili kushishino, njengoko kuchaziwe ngezantsi:

I. Indawo ephambili yeeFurnaces zeGraphitization eziqhubekayo

1. Umgaqo weNkqubo

Izitofu ze-graphitization eziqhubekayo ziguqula iimolekyuli zekhabhoni kwi-petroleum coke ukusuka kwilungiselelo elingacwangciswanga ukuya kwisakhiwo se-lattice esinama-hexagonal, esicwangciswe ngokulinganayo ngokusebenzisa ubushushu obuphezulu (malunga ne-3000°C) kunye nonyango lombane. Le nkqubo inika i-petroleum coke amandla aphezulu ombane kunye nokuzinza kobushushu, okwenza ukuba ibe sisixhobo esihle kakhulu sekhabhoni kunye nezinto eziluhlaza kwii-electrodes ze-graphite.

2. Iingenelo zokuthelekisa ishishini

• Isithando somlilo sendabuko saseAcheson: Sifuna ukulayishwa kweebhetshi, ukufudumeza, kunye nokupholisa, nto leyo ebangela ukusetyenziswa kwamandla aphezulu kunye namaxesha amade okujikeleza (malunga neentsuku ezili-15-20). Ukongeza, kufuneka ubungakanani obukhulu bezinto zokukhusela (ezifana ne-coke) ukuze zizaliswe, nto leyo ekhokelela kwiindleko eziphezulu kunye nokusebenza okuphantsi.
• Isithando Somlilo Esiqhubekayo Sokugalela Imifanekiso: Sivumela ukondliwa okuqhubekayo, ukwenziwa kwemifanekiso, kunye nokukhupha izinto ezikrwada, kunye nesithando esinye esikwaziyo ukuvelisa iitoni ezingama-50-100 ngosuku. Ukusetyenziswa kwamandla kuncitshiswa ngama-30%-50%, kwaye akukho mfuneko yokuzalisa, nto leyo enciphisa ukuveliswa kwenkunkuma.

II. Iimpawu zobuchwepheshe zeZithando eziQhubekekayo zeGraphitization

1. Ukusebenza kakuhle kakhulu kunye nokugcinwa kwamandla

Umzimba wesithando usebenzisa isakhiwo sokukhusela esineeleya ezininzi (umz., i-carbon felt, i-graphite felt) ukunciphisa ukulahleka kobushushu, okunyusa ukusebenza kakuhle kobushushu ukuya kuthi ga kwi-80%. Inkqubo yokufudumeza ukumelana inika ulawulo oluchanekileyo lobushushu, ithintela ubushushu obugqithisileyo okanye ubushushu obungaphantsi kobushushu kwaye iqinisekisa umgangatho ozinzileyo we-graphitization.

2. Ulawulo Oluzenzekelayo

Ixhotyiswe ngenkqubo yolawulo ye-PLC, isoloko ijonga iiparameter ezifana nobushushu, uxinzelelo, kunye nombane, ilungisa ngokuzenzekelayo amandla okufudumeza kunye nesantya sokondla. Amandla okujonga kude axhasa izilumkiso zempazamo kunye nokwenza ngcono inkqubo, okunciphisa ukungenelela ngesandla.

3. Ukusebenza kokusingqongileyo

Uyilo lwesithando esivalekileyo lunciphisa uthuli kunye nokukhutshwa komoya ophumayo, ngelixa iiyunithi ezihlanganisiweyo zokususa i-sulfurization kunye nokususa uthuli zihlangabezana nemigangatho yokusingqongileyo. Inkqubo yokubuyisela ubushushu benkunkuma isebenzisa ubushushu bomoya ukufudumeza kwangaphambili izinto ezikrwada, nto leyo enciphisa ukusetyenziswa kwamandla ngakumbi.

III. Izixhobo ezingundoqo kunye nemisebenzi yazo

1. Ulwakhiwo lweSithando somlilo

• Indawo Yokufudumeza: Yenziwe ngee-electrodes ze-graphite okanye iintambo zokumelana, inika indawo enobushushu obuphezulu.
• Umaleko wokukhusela: Usebenzisa i-carbon felt okanye i-graphite felt ukunciphisa ukulahleka kobushushu.
• Inkqubo Yokutya: Ii-screw conveyors okanye ii-feeders ezingcangcazelayo ziqinisekisa ukunikezelwa kwezinto eziluhlaza rhoqo nangokulinganayo.
• Inkqubo Yokukhupha: Izixhobo ezipholiswe ngamanzi okanye ezipholiswe ngumoya zipholisa ngokukhawuleza iimveliso ezinegrafiti ukuthintela i-oxidation.

2. Izixhobo ezincedisayo

• Umatshini wokutyumza nokuhlola: Uqhekeza i-petroleum coke eluhlaza ibe ngamasuntswana angama-1-6mm ukuqinisekisa ukufudumeza okufanayo.
• Inkqubo yokususa uthuli: Izihluzi zeengxowa okanye ii-precipitators ze-electrostatic ziqokelela uthuli kwaye zicoce iigesi zokukhupha uthuli.
• Inkqubo yoLawulo: Iinkqubo ze-PLC okanye ze-DCS zivumela ukusebenza ngokuzenzekelayo kuyo yonke inkqubo.

IV. Amatyala okusetyenziswa kunye neenzuzo zoqoqosho

1. Iiprojekthi eziqhelekileyo zasekhaya

Inkampani yamkele isithando somlilo esiqhubekayo sokuvelisa izongezo zekhabhoni ze-petroleum coke carbon, nto leyo eyafikelela kwimveliso yemihla ngemihla yeetoni ezingama-80 ngesithando somlilo. Ukusetyenziswa kombane ngetoni nganye kwehle ukusuka kwi-6000 kWh kwizithando zomlilo zemveli ukuya kwi-3500 kWh, nto leyo eyasindisa ngaphezulu kwezigidi ezilishumi zeeyuan kwiindleko zombane zonyaka. Umxholo wekhabhoni ozinzileyo wemveliso yi-≥98.5%, kwaye umxholo wesalfure yi-≤0.05%, ufikelela kwimigangatho yamazwe ngamazwe ephucukileyo kwaye uthatha indawo yeemveliso ezingenisiweyo.

2. Iindlela zoPhuhliso lwaMazwe ngaMazwe

Itekhnoloji ye-graphitization eqhubekayo yamkelwe ngokubanzi eYurophu nase-United States, idibene neenkqubo zolawulo ezikrelekrele zemveliso engenamntu. Iinkampani zaseJapan zilungiselele izakhiwo zesithando ukulawula ukulingana kobushushu be-graphitization ngaphakathi kwe-±5°C, nto leyo ephucula ukuhambelana kwemveliso.
