Njengesixhobo esibalulekileyo semveliso yeekhemikhali zangoku, inkqubo yokubala yobushushu obuphezulu bepetroleum coke inefuthe elibalulekileyo kumgangatho kunye nesivuno sepetroleum coke. Kweli phepha, iteknoloji yokubala ukushisa okuphezulu kwe-petroleum coke ixutyushwa ngokudibanisa nokubaluleka kwemveliso. Ngokubhekiselele kumashishini.
Ukubaluleka kokuveliswa kwe-petroleum coke ngokubalwa kobushushu obuphezulu
I-calcination ye-petroleum coke yenye yeenkqubo eziphambili ekuveliseni i-anode ye-aluminium. Injongo yalo kukususa i-volatiles kwizinto eziluhlaza kunye nokuphucula ukuxinana, amandla omatshini, ukuhanjiswa kombane kunye nokuzinza kweekhemikhali zezinto eziluhlaza. Ngethuba lenkqubo yokubala, ukubunjwa kwe-elemental kunye nesakhiwo sombutho we-petroleum coke sitshintshile, kwaye iimpawu ezibonakalayo kunye neekhemikhali zezinto eziluhlaza ziphuculwe kakhulu emva kokubala.
Le propati ikhethekileyo yemveliso inokuhlangabezana nemveliso yeekhemikhali ngakumbi, ukuze amanye amashishini amashishini aphinde asebenzise. Kwinkqubo yokubala, ukucokiseka kwe-calcination degree kunye ne-pertinence yenkqubo yokubala kuya kuchaphazela ukukhutshwa kunye nokuchaneka kwe-petroleum coke. Ke ngoko, kubaluleke kakhulu ukufunda itekhnoloji yokubala ubushushu obuphezulu bepetroleum coke.
Uhlalutyo lobuchwephesha be-calcined petroleum coke kwiqondo lokushisa eliphezulu
Ukudibanisa kunye norhwebo lweekhemikhali zelizwe lethu kwi-calcine ifikelela kwiimfuno ezahlukeneyo zomgangatho, ukhuseleko, izinga lemveliso kunye nokunye kwemveliso ye-petroleum coke, iindlela ezikhoyo zobushushu obuphezulu belizwe lethu zezi: i-rotary kiln, i-oveni ye-coke, isithando somlilo setanki. , njl. Umgaqo, iimpawu, ukusetyenziswa kunye nezalathi zezoqoqosho zetekhnoloji ezininzi zokubala zithelekiswa ukwenzela ukubonelela ngereferensi yemveliso yeshishini.
(1) Iteknoloji ye-Rotary kiln calcining
1. Uhlalutyo lwemigaqo: Itekhnoloji ye-rotary kiln edibeneyo kunye nesakhiwo esikhethekileyo somzimba we-rotary kiln inokufikelela kunyango olusebenzayo lobushushu lwe-coke eqinile ye-petroleum. Umgaqo wetekhnoloji ye-rotary kiln kukuxhomekeka ekunyukeni kwamaqondo obushushu angaphandle kwinkqubo yepetroleum coke calcination kunye nesenzo sekhemikhali ngaphakathi kwisantya sokujikeleza, ukuze kukhawuleziswe izinga lokutsha kwepetroleum coke kunye nokwenza icoke yepetroleum eveliswe ngubushushu obuphezulu. calcination.
2. Itekhnoloji yerotary kiln ikakhulu inezi nkqubo zilandelayo:
I-1) Ukufudumala: ngokujikeleza ngokukhawuleza i-cylinder kunye nokongeza izinto ezithile ezivuthayo ukwenza i-petroleum coke yangaphakathi ifikelele kwindawo yokutshisa kwaye itshise ngokukhawuleza;
I-2) Ukubala: ukukhawulezisa kwangaphandle kokujikeleza kwe-cylinder, ngelixa ukwandisa ukushisa kwe-calcination, i-petroleum coking chemical reaction yangaphakathi iqiniswe;

I-3, iingenelo kunye nokungalungi kunye nohlalutyo olusebenzayo: kudityaniswe nemveliso yemizi-mveliso emikhulu, i-rotary kiln ineempawu zokusebenza okulula, imveliso enkulu, ixabiso eliphantsi, ukugcinwa okufanelekileyo, njl., Inokusebenza ngokufanelekileyo kumashishini iminyaka engama-20 ukuya kwe-30, ilungele iintlobo ezahlukeneyo zokusetyenziswa kwe-carbon petroleum coke. Ngelo xesha, i-rotary kiln ngokwayo isebenzisa umgaqo wokujikeleza kunye nekhemikhali yokusabela kwezinto zangaphakathi zokutsha ukugcina ixabiso lezinto ezivuthayo. Nangona kunjalo, xa i-petroleum coke ijikeleza kwi-cylinder axis, ukushisa okuphezulu kulula ukubangela ukugqoka kunye nokuwa kwe-refractory, okubangelwa umgangatho ongazinzanga wemveliso ye-calcined, phakathi kwayo ukuveliswa kokuchaneka okuphezulu malunga ne-10% kuphela. .
Ngoko ke, kudityaniswe neempawu ze-rotary kiln, amashishini kufuneka aqhube unyango olujoliswe kuyo lwezixhobo zokwakha eziko kunye neenkqubo ngexesha lokusebenza, ukuze kuhlangatyezwane neemfuno zokuphucula ukusebenza kakuhle kwemveliso yemizi-mveliso, ukomeleza ukuqina kwe-calcination kunye nokuphucula ukuchaneka kwemveliso kangangoko kunokwenzeka.
(2) Itekhnoloji ye-coke ye-oven calcination
1. Uhlalutyo lomgaqo: I-coke ye-oven calcination calcination i-coke eye yaphathwa ngokukodwa ngeziko lobushushu eliphezulu le-calcination eyenziwe ngeebhloko zezitena ezinokumelana nomlilo ophezulu, kwaye i-coke eveliswayo iphantsi kwaye iphathwa ukwenza iimveliso ezintle ezifunwa lishishini ukuvelisa i-coke. . Kule nkqubo, kukho iimfuno ezingqongqo kakhulu kwi-batching ye-coke eluhlaza kunye nobushushu kunye nexesha lokubala kwe-coke.
I-2, inzuzo kunye nokungonakali kunye nohlalutyo olusebenzayo: xa kuthelekiswa neteknoloji ye-rotary kiln, i-oven ye-coke inemveliso ephezulu kunye neempawu ezichanekileyo. Ikhetha ukujongana noluhlu olubanzi lwezithako, inokufezekisa ulawulo oluzenzekelayo ekusebenziseni, inokuvelisa umgangatho ophezulu we-coke ogqityiweyo kumashishini. Ngelo xesha, imveliso ye-oven ye-coke nayo ijongene neengxaki ezithile zokwakha, iimfuno eziphezulu zokwakhiwa kwe-oven ye-coke, ukuchaneka okuphezulu kokulawulwa kokushisa kwesithando somlilo, iindleko eziphezulu zokugcina iindleko ziya kuchaphazela izinga lokungena kwegalelo lokuvelisa i-oven coke.
Nangona kunjalo, kuphuhliso lwetekhnoloji ye-petroleum coke calcination kwixesha elizayo, ukubalwa kwe-oven ye-coke kunokuqonda indima yokonga amandla kunye nokunciphisa ukukhutshwa, kwaye kunokwenza igalelo elithile kukhuseleko lokusingqongileyo kunye nokusetyenziswa okubanzi kwamandla, i-coke oven calcination inethemba lophuhliso olubanzi. .
(3) iteknoloji ye-tank calciner
1. Uhlalutyo lwemigaqo: Izakhiwo eziphambili ze-canne-type calcination furnace zibandakanya: itanki yokutya, i-passage yomlilo, igumbi lokutshintshiselana ngobushushu, ukondla kunye nokukhupha isixhobo, isixhobo sokujikeleza kwamanzi okupholisa, njl njl. Kwinkqubo yokubala ukushisa okuphezulu, i-petroleum coke yongezwa. ukuya kwitanki iqonda ukusabela okuqhubekayo kwezinto zekhabhoni zangaphakathi ngokusebenzisa izinto zangaphakathi ezisisigxina, ukuze kugqitywe ukubala kobushushu obuphezulu. Itanki yokubala eqhelekileyo inokwahlulwa ibe yi-downflow calcination kunye ne-counterflow calcination ngokweqondo kunye necala lokuphuma komsi.
I-2, uhlalutyo oluluncedo kunye nolungalunganga kunye nohlalutyo olusebenzayo: uhlobo lwe-canner calcination furnace lusetyenziswa kakhulu kwilizwe lethu, yeyona ndlela iphambili yeshishini lelizwe lethu lekhabhoni, ngonyango olukhethekileyo lwepetroleum coke inokuhlangabezana nobushushu ngokupheleleyo, iimfuno zokufudumeza ngokuthe ngqo, kwaye indawo yangaphakathi inokunqanda ukudibana komoya, ukunciphisa izinga lokulahleka kwe-oxygen, ukuphucula imveliso kunye nomgangatho weemveliso ezigqityiweyo. Nangona kunjalo, xa usamkela itekhnoloji ye-canister calciner, zininzi iinkqubo zokusebenza ngesandla, ezinyusa umngcipheko wokhuseleko. Ngelo xesha, i-tank calciner ngokwayo ineemfuno ezininzi zemingxuma, ezibangela ubunzima bokugcinwa.
Kwixesha elizayo, amashishini angakwazi ukufunda ngakumbi itekhnoloji ye-canister calcination ukusuka kubuninzi bokukhupha, uphando lwengozi yeempazamo kunye neminye imiba, ukuze kuphunyezwe injongo yokunyusa imveliso ye-petroleum coke yokubala ubushushu obuphezulu.
Ukushwankathela, ukushisa okuphezulu kwe-petroleum coke calcination kunempembelelo enkulu kwishishini lemichiza kunye ne-aluminium yelizwe lethu. Amashishini anokukhetha itekhnoloji efanelekileyo yokubala ubushushu obuphezulu ngokweemfuno zabo zemizi-mveliso, kwaye ekugqibeleni baqonde ukuncitshiswa kweendleko kunye nokunyuka ngokufanelekileyo kwamashishini.
