Uhlalutyo lweNdlela:
Isiganeko Sokuqhuma (Ukuqhuma):
- Ukuphuma ngokukhawuleza kwezinto eziguquguqukayo: Xa umxholo oguquguqukayo kwi-petroleum coke uphezulu, njengoko ubushushu bunyuka ngexesha lokuqala kwe-calcination, izinto eziguquguqukayo ziphuma ngokukhawuleza. Ukuba izinga lokuphuma likhawuleza kakhulu, uxinzelelo olukhulu lomphunga luyaqokelelana ngaphakathi kwamasuntswana e-petroleum coke, nto leyo ekhokelela ekuqhumeni.
- Ulawulo lobushushu olungafanelekanga: Ubuninzi bezinto eziguquguqukayo ziyaphuma kumaqondo obushushu e-calcination aphakathi kwama-600–700°C. Ukuba ubushushu bunyuka ngokukhawuleza kakhulu ngeli nqanaba, izinto eziguquguqukayo ziyaphuma ngamandla, nto leyo eyonyusa ukuqhuma.
Ingxaki yokutyibilika:
- Ukutsha okungaphelelanga kwezinto eziguquguqukayo: Ngexesha lokutsalwa kwe-coke ye-petroleum eguquguqukayo ephezulu, ukutsha okungaphelelanga kwezinto eziguquguqukayo kuvelisa inani elikhulu le-carbon black kunye nezinto ezingatshiyo.
- Ukunyibilika kothuthu: Uthuthu olukwi-petroleum coke luyanyibilika kubushushu obuphezulu kwaye ludibane nezinto ezingatshiyo ukuze zenze imixube ye-eutectic ene-low-melting-point enamathela eludongeni okanye kwizixhobo ze-oven, nto leyo ekhokelela ekuqhekekeni.
- Ubushushu obugqithisileyo: Xa ubushushu be-calcination budlula ubushushu obuthambileyo bothuthu, uthuthu luyanyibilika luze lunamathele, lwenze i-slag.
Amanyathelo okuthintela:
Ulawulo lobushushu beCalcination kunye nesantya sokufudumeza:
- Ukufudumeza ngokwezigaba: Ngexesha lokuqala kwe-calcination, sebenzisa izinga lokufudumeza eliphantsi ukuvumela i-volatile matter ukuba iphume kancinci, uphephe uxinzelelo olugqithisileyo lomphunga wangaphakathi. Umzekelo, ukufudumeza kancinci ngaphambi kwe-900°C kunokuphucula isivuno sokwenyani.
- Ulawulo lobushushu obuphezulu kwinqanaba lobushushu: Kubushushu obuphezulu (umz., 1240–1300°C), nciphisa ngokufanelekileyo izinga lokufudumeza ukunceda ukuphucula uxinano lokwenyani kunye nokumelana ne-oxidation kwe-calcined coke, ukunciphisa umngcipheko we-slagging.
Ukuphucula ukusebenza kwezixhobo zeCalcination:
- Gcina umgangatho wezinto ezisetyenziswayo uphantsi: Kwii-ovens zeembiza, gcina umgangatho wezinto ezisetyenziswayo uphantsi ukuvumela i-petroleum coke eyongeziweyo ukuba ikhuphe ngokukhawuleza izinto eziguquguqukayo, inciphise ixesha lokuhlala kwayo kwi-oven kwaye inciphise amathuba okutsalwa yi-slagging.
- Yongeza uxinzelelo olubi: Gcina uxinzelelo olubi oluphezulu ukuze kube lula ukukhupha izinto eziguquguqukayo kunye nokuthintela ukuqokelelana kwazo ngaphakathi kwesithando somlilo.
- Coca rhoqo iindawo zokukhupha izinto eziguquguqukayo: Coca rhoqo iindawo zokukhupha izinto eziguquguqukayo kunye neendlela zokuqokelela izinto eziguquguqukayo ukuze uthintele ukuvaleka nokuqinisekisa ukuba izinto eziguquguqukayo zikhutshwa ngaphandle kokuphazamiseka.
Uhlengahlengiso lweeRatios zezinto eziluhlaza:
- I-Mixed calcination: Yongeza i-coke ye-petroleum eguquguqukayo kancinci okanye i-coke ene-calcined kwi-coke ye-petroleum eguquguqukayo kakhulu ukuze unciphise umxholo we-volatile iyonke. Qinisekisa ukuba ulungelelwaniso oluchanekileyo kunye nokuxuba okufanayo ukuze uphephe umxholo we-volatile ophezulu kwindawo ethile.
- Lawula ubungakanani bamasuntswana ezinto ezikrwada: Susa izinto ezinkulu kakhulu kunye nokungcola kwesinyithi ukunciphisa umxholo wezinto ezingaphiliyo kunye nokunciphisa imithombo ye-slagging.
Ukuphuculwa kweeParamitha zeNkqubo:
- Ulawulo olufanelekileyo lomxholo weoksijini: Gcina umxholo weoksijini ofanelekileyo ukuze uphephe ukunciphisa imozulu ehlisa inqanaba lokunyibilika kothuthu. Umzekelo, xa umxholo weoksijini ungaphantsi kwe-5%, inqanaba lokunyibilika kothuthu liyancipha nge-100–150°C, nto leyo enyusa umngcipheko wokutsalwa yi-slagging.
- Lungisa usasazo lomoya: Lungisa umlinganiselo wosasazo lomoya ngokwesigaba se-calcination ukuqinisekisa ukutsha ngokupheleleyo kwezinto eziguquguqukayo kunye nokunciphisa ukuveliswa kwe-carbon black kunye nezinto ezingatshanga.
Ukulungiswa kunye nokugcinwa kwezixhobo:
- Guqula izixhobo ze-calcination: Kwi-petroleum coke ene-volatile ephezulu, tshintsha ngokukodwa ii-rotary kilns okanye ii-pot furnitures, njengokongeza iziteshi zokukhupha izinto eziguquguqukayo kunye nokwenza ngcono ukusasazwa komoya wangaphakathi, ukuze kuhambelane neemfuno ze-calcination zezinto ezine-volatile ephezulu.
- Ukuhlolwa kwezixhobo rhoqo: Qinisekisa ukuba izixhobo zisebenza ngendlela eqhelekileyo ukuthintela ubushushu obuphezulu okanye ukuhamba komoya okungahambi kakuhle okunokubangela ukubola. Umzekelo, hlola izitshisi kunye nemijelo yomlilo kwaye ucoce ngokukhawuleza uthuthu kunye nenkunkuma eqokelelweyo.
