Ese ubushuhe buri muri coke mbisi bugomba kumywa ku ngufu mbere yo gukaraba?

Muri rusange, ni ngombwa kumisha ku ngufu ubushuhe buri muri coke mbisi mbere yo kuyitera calcium, cyane cyane mu bihe bikurikira aho kumisha ari ingenzi:

I. Ingaruka mbi z'ubushuhe ku buryo bwo gukaranga

1. Ingaruka ku mikorere myiza y'ibintu bihindagurika

Iyo coke mbisi (nka peteroli coke na anthracite) irimo ubushuhe bwinshi, amazi ahinduka mu kirere atwara ubushyuhe bwinshi, bigatuma ubushyuhe buhindagurika mu itanura rya calcination mu cyiciro cya mbere. Ibi bigira ingaruka ku gusohoka neza kw'ibintu bihindagurika (nk'ibinyabutabire bya sulfur na hydrogen). Urugero, coke ya peteroli ahanini isohora ubushuhe buri munsi ya 200°C. Iyo ubushuhe budakuweho neza, icyiciro cyo gusohora ibintu bihindagurika (500-700°C) gishobora gutinda bitewe n'ubushyuhe budahagije, bigatuma ibikoresho fatizo bigabanuka ku buryo butari bumwe ndetse n'ibyago byo kwangirika kw'ibicuruzwa.

2. Kugabanya imiterere y'ibikoresho fatizo

Ubushuhe bugabanya imikoranire hagati y’uduce tw’ibikoresho fatizo, bigatuma ibikorwa byo gutunganya mbere nko gusya, gupima no gusya bigorana. Urugero, peteroli coke ifite ubushuhe burenga 10% ikunze kuziba ibikoresho mu gihe cyo gusya kandi igatanga uduce duto tudahuje nyuma yo gusya, ibyo bigira ingaruka ku bwiza bw’ibikorwa byo kuvanga no gukora nyuma.

3. Kongera ikoreshwa ry'ingufu n'ibiciro

Guhindura ubushuhe bisaba ubushyuhe bwiyongereye. Iyo butamaze kuyumishwa, itanura rya calcination rigomba gukoresha lisansi nyinshi kugira ngo ubushyuhe bukomeze kugumana. Dufashe urugero rwa peteroli coke, kugabanya ubushuhe ku kigero cya 1% bishobora kuzigama kilojoule zigera kuri 20 kuri kilo imwe y'ubushyuhe, kandi uburyo bwo kumisha bushobora kugabanya cyane ikiguzi cy'umusaruro.

II. Kongera Ubwiza bwa Calcination binyuze mu Kumisha

1. Kunoza Ubucucike n'Imbaraga by'Ibikoresho Bisanzwe

Nyuma yo kuma, ubushuhe bw'ibikoresho fatizo bugabanuka munsi ya 0.3%. Mu gihe cyo gukaraba, isohoka ry'ibintu bihinduka rirushaho kuba ryiza, kandi ingano y'ibikoresho fatizo iba ingana. Ubucucike nyakuri (urugero, kwiyongera kuva kuri 1.42-1.61 g/cm³ kugeza kuri 2.00-2.12 g/cm³ kuri peteroli) hamwe n'imbaraga za mashini z'ibikoresho fatizo birarushaho kwiyongera, bigabanya igabanuka ry'ibicuruzwa mu gihe cyo guteka.

2. Kongera ubushobozi bwo gutwara ibintu no kurwanya ogisijeni

Mu gihe cyo gukaranga, imiterere ya molekile y’ibikoresho fatizo irahinduka, kandi ubushobozi bwo kugabanya ingufu bugabanuka (urugero, ubushobozi bwo kugabanya ingufu za peteroli coke bugabanuka uko ubushyuhe bwa kalcina bugenda bwiyongera), bigatuma ubushobozi bwo gutwara ibintu burushaho kwiyongera. Hagati aho, agace ka carbonique ka pyrolytic karubone kaba ku buso bw’uduce, kakongera ubushobozi bwo kurwanya oxidation kandi kakongera igihe cyo gukora cy’ibicuruzwa.

3. Kunoza uburyo bwo guhagarara neza

Ibikoresho byumye bifite ubushuhe buringaniye bishobora kwirinda ihindagurika rikomeye ry’ubushyuhe mu itanura rya calcination no kugabanya kwangirika k’ubushyuhe ku bikoresho. Urugero, mu kugenzura ubushuhe bw’amakara yinjira mu itanura rya coke munsi ya 3%, inganda za coke zishobora kongera igihe cyo kubaho cy’amatanura ya coke ku myaka irenga 10 no kugabanya igipimo cyo guhinduka kw’inkuta z’icyumba cy’amatanura ya coke ku kigero cya 90%.

III. Ibisabwa mu buryo bwo kumisha

1. Kugenzura ubushyuhe n'igihe

Ubushyuhe bwo kumisha busanzwe buri hagati ya 110-130°C, kandi igihe kigomba guhindurwa hakurikijwe ingano y'uduce n'ubushuhe bw'ibanze bw'ibikoresho fatizo. Urugero, peteroli coke ifite uduce turi munsi ya mm 3 isaba amasaha agera kuri 2-4 yo kumisha kugira ngo habeho ihuma ry'ubushuhe rimwe.

2. Guhitamo ibikoresho

Ibikoresho bisanzwe byo kumisha birimo amatanura azunguruka n'amatanura yumisha ingoma. Amatanura yumisha akora neza binyuze mu gushyushya hakoreshejwe uburyo bwo kuvura, mu gihe amatanura yumisha ingoma agabanya gufatana kw'ibikoresho kandi akanoza imikorere myiza yo kumisha hakoreshejwe amasahani y'imbere n'ibikoresho byo gusukura.

3. Ingamba zo kubungabunga ibidukikije n'umutekano

Sisitemu yo kumisha igomba kuba ifite ibikoresho byo gukuraho ivumbi (nk'ibikusanya ivumbi ry'inkubi y'umuyaga + ibikusanya ivumbi ry'amazi) kugira ngo igabanye ivumbi ry'imyuka, rifite ubushobozi bwo gukuraho ivumbi kugeza kuri 99% cyangwa birenga. Hagati aho, sisitemu yo gutwika ikoresha icyuma gitwika gikoresha gazi, cyoroshye gukoresha kandi cyizewe.
