Yiziphi izinto ezibamba ulayini zengxenye ngayinye yesitofu somlilo oshisayo?

Ukuhlaziywa kokulungiswa kwe-refractory kwengxenye ngayinye yesitofu somlilo oshisayo kwabelwana ngabakhiqizi bezitini eziphikisayo.

I-blast furnace hot blast stove iyisishintshi sokushisa esivuselelayo, ikakhulukazi ukuhlinzeka ngendawo yokushisa ephezulu yomoya ovuthayo wesithando somlilo ukuze kuzuzwe izinga lokushisa eliphezulu lomoya lokusebenza, ngokuvamile i-1200 ~ 1350 ℃. Izithando zomlilo ezishisayo ezifanayo ezivamile zingu-3~4. Ukuze kuhlangatshezwane nezidingo zomthombo wokushisa okushisa okuphezulu kanye nesikhathi eside sesevisi yezithando zomlilo ezishisayo, izinto eziphikisayo zamaziko okushisa ashisayo kufanele zibe nezici zokumelana nokushisa okuphezulu nokumelana nokucindezela okuphezulu, ukumelana okuhle kokukhasa, umthamo omkhulu wokushisa othize, kanye conductivity ezinhle ezishisayo. .

Ngokwesakhiwo sengxenye ngayinye yesitofu esishisayo esishisayo kanye nomthelela wesimo somlilo, izinto eziphikisayo zesitofu esishisayo zingahlukaniswa zibe izingxenye ezimbili: izinga lokushisa eliphezulu nokushisa okuphansi. Izingxenye zokushisa eziphakeme: kufaka phakathi ingxenye engaphezulu yegumbi elivuthayo, izitini zokuhlola engxenyeni engenhla ye-regenerator, izitini ezinkulu zodonga, phezulu kwesithando somlilo, njll; izingxenye zokushisa eziphakathi nendawo eziphansi: kufaka phakathi izingxenye ezimaphakathi neziphansi zegumbi elivuthayo, izitini ze-checkered phakathi nezingxenye eziphansi ze-regenerator, izitini ezinkulu zodonga, nezingxenye zokuphuma, njll.

Ngokwesakhiwo sesitofu esishisayo, singahlukaniswa sibe: phezulu kwesithando somlilo, udonga olukhulu lwe-regenerator, isitini sokuhlola, udonga lokuhlukanisa, udonga olukhulu lwegumbi lomlilo, umshini wokushisa nezinye izingxenye. .

1. I-Refractory phezulu kwesithando somlilo:

Phezulu kwesithando somlilo kutholakala endaweni yokushisa ephezulu ngaphakathi kwesithando somlilo esishisayo, lapho izinto eziphikisayo zithintana ngokuqondile nomoya oshisayo kanye negesi ye-flue. Izinto eziphikisayo ezinokumelana nokushaqeka okushisayo okuqinile kanye nokumelana nokukhasa kufanele kukhethwe. Ngokuvamile, izitini ze-silica nezitini zobumba ezinwabuzelayo eziphansi zingasetshenziswa. Izitini eziphakeme ze-alumina, izitini eziphakeme ze-alumina ezifaka i-alumina, izitini ze-mullite, izitini zobumba ezilula, izitini ze-andalusite, upende wesifutho ongazweli i-asidi, upende lwesifutho sobumba, njll.

2. Izinto eziphikisayo zodonga olukhulu lweregenerator:

Udonga olukhulu lwe-regenerator luwudonga olukhulu lwesitofu sokushisa okushisayo, lapho izinga lokushisa eliphezulu liphakeme ngokuqhathaniswa, futhi izinga lokushisa lomoya phakathi nezingxenye eziphansi liphansi kakhulu. Ingxenye engaphezulu yodonga olukhulu lokuvuselela kabusha ingasebenzisa izitini ze-silica, izitini ezisezingeni eliphansi ze-alumina ephezulu, kanye nokushisa okuphezulu kwe-aluminium. Izitini, izitini ze-mullite, izitini zobumba olula, upende wesifutho ongazweli i-asidi, upende olula wokufutha, njll.

Engxenyeni ephakathi, izitini eziphansi ze-alumina eziphakeme, izitini ze-mullite, izitini ze-andalusite, izitini zobumba ezilula, upende wesifutho sobumba, upende olula wokufutha, njll.

Ingxenye engezansi ingasebenzisa izitini zobumba, izitini eziphakeme ze-alumina, izitini zobumba ezilula, izitini eziphakeme ze-alumina, izinsimbi zobumba, izifutho zopende ezikhanyayo, ukhonkolo ongashisi, njll.

3. Izinto eziphikisayo zezitini zoshekha:

Indawo ephezulu yokushisa ephezulu yezitini zokuhlola ze-regenerator kufanele yenziwe ngezinto eziphikisayo ezinokuqina okuhle kwevolumu yokushisa okuphezulu, ukubola kanye nokumelana nokukhasa. Izingxenye ezimaphakathi neziphansi zithwala ukucindezela okukhulu okuvela ezintweni eziphezulu eziphikisayo. Ngaphezu kokwanelisa ukusebenza kwayo kokukhasa, idinga futhi ukusebenza kahle kwamandla ayo okucindezela okushisa avamile kanye nokuzinza kokushisa okushisayo.

Ingxenye engaphezulu yezitini zokuhlola ngokuvamile isebenzisa izitini zokuhlola i-silicon nezitini zokuhlola ze-aluminium ephezulu, ingxenye ephakathi isebenzisa izitini zokuhlola ezine-aluminium ephezulu neziphakeme ze-aluminium, kanti ingxenye engezansi isebenzisa okuhlola i-aluminium ephezulu ephansi. izitini nezitini zokuhlola ubumba.

Ngaphezu kwalokho, umshini wokuvuselela isitofu esiyisiyingi se-hot blast ngokuvamile sisebenzisa amabhola aphikisayo esikhundleni sezitini zokuhlola, okuvame kakhulu amabhola aphikisayo e-alumina aphezulu, futhi amabhola aphikisayo obumba angasetshenziswa ezindaweni ezishisayo.

4. Izinto eziphikisayo zezindonga zokuhlukanisa:

Udonga lokuhlukanisa luwudonga lwezitini oluphikisayo oluhlukanisa i-regenerator kanye negumbi lomlilo. Ubude bodonga lokuhlukanisa ngokuvamile buphakeme ngo-400 ~ 700mm kunezitini zokuhlola ze-regenerator ukuqinisekisa ukusatshalaliswa komoya okufanayo. Ngenxa yomehluko omkhulu wezinga lokushisa phakathi kwezinhlangothi ezimbili zodonga lokuhlukanisa, umehluko wokunwebeka okushisayo wodonga uba mkhulu, okubangela ukuthi izinto eziphikisayo zodonga lokuhlukanisa ziwohloke, zigobe futhi ziqhekeke. Ngakho-ke, izitini ze-silica nezitini eziphakeme ze-alumina zingasetshenziswa engxenyeni engenhla yezinto eziphikisayo zodonga lokuhlukanisa.

Izitini eziphezulu ze-alumina kanye nezitini zokufakelwa kwe-aluminium ephezulu zingasetshenziswa phakathi nendawo, futhi izitini ezisezingeni eliphansi ze-alumina ephezulu kanye nezitini zokufakelwa kwe-aluminium ephezulu zingasetshenziswa engxenyeni yokushisa okushisayo.

Izitini zobumba nezitini zobumba ezilula zingasetshenziselwa ingxenye engezansi.

5. Izinto eziphikisayo zodonga olukhulu lwegumbi elivuthayo:

Udonga olukhulu lwegumbi lomlilo ngokuyisisekelo lufana nezinto eziphikisayo ze-regenerator. Ingxenye engenhla ingasebenzisa izitini ze-silica, izitini eziphakeme ze-alumina, izitini eziphakeme ze-alumina zokufaka i-alumina, izitini ezikhanyayo ze-silica, izitini zobumba ezilula, upende wokufutha, njll.

Izitini eziphezulu ze-alumina, izitini ezisezingeni eliphansi ze-alumina ephezulu, izitini zokufakelwa kwe-alumina ephezulu, izitini zobumba ezikhanyayo, upende wesifutho, njll. zingasetshenziswa phakathi.

Ingxenye engezansi ingasebenzisa izitini zobumba, izitini eziphakeme ze-alumina, izitini zobumba ezingasindi, upende wesifutho, ukhonkolo ongashisi, njll.

6. Imbobo yokushisa umlilo:

I-burner nozzle iyisisetshenziswa esithumela umoya oxubile wegesi ekamelweni lokuvutha ukuze ushise. Kukhona izinto zensimbi neze-ceramic. Njengamanje, iningi lama-burners e-ceramic asetshenziswa. Ukuze uqinisekise ukuqina komoya, ubuqotho kanye nempilo yesevisi ye-nozzle yokushisa, kuyadingeka ukuthi i-coefficient yokwandisa umugqa kanye nokumelana nokukhuphuka kwama-refractories lapha kuhle, ngakho-ke i-burner burner ingenziwa nge-mullite, i-mullite-cordierite, ephezulu. -i-aluminium-cordierite, i-high-aluminium castable preforms, njll.

7. Izinto ezizibambisayo zezinye izingxenye zesitofu esishisayo:

(1) Izinto ezibambayo zamapayipi omoya oshisayo, okuhlanganisa amapayipi amakhulu okuhambisa umoya, amapayipi amagatsha kanye namapayipi azungeze umoya oshisayo. Ngokuvamile, yenziwe ngezitini zobumba ezilula, futhi indawo yokukhipha umoya oshisayo kanye ne-interface ye-air duct enkulu ingenziwa ngezitini eziphezulu ze-alumina nezitini ze-mullite. Isitofu esishisayo esizungeze ipayipi kanye nepayipi legatsha lokuphakelwa komoya kungathelwa ngokuhlangene nge-alumina ephezulu yesimende esikhanyelayo futhi esikwazi ukuphonswa nge-phosphate refractory.

(2) I-valve yomoya oshisayo yenziwe ngezinto eziphikisayo, ngakho izinhlangothi zombili ziyafudumala futhi zingaphansi kokudlidliza kwemishini, ukugqwala kanye nokushintsha kwezinga lokushisa. Impilo yokwakhiwa kwezitini zobumba kanye nezitini eziphakeme ze-alumina yi-6 kuya ku-Okthoba, futhi kusetshenziswa izinsimbi eziphezulu ze-alumina ze-samente refractory. Ukuthulula impilo yokubumba ingafinyelela cishe iminyaka eyi-1.5.

(3) Izinto ezikwazi ukuphikisa zisetshenziselwa umshini wokuqhafaza noshimula. Ushimula we-flue usetshenziselwa kakhulu ukukhipha igesi ephumayo. I-flue gas yinde kune-flue gas. Ngakho-ke, izinto ze-flue refractory zingakhiwa ngezitini zobumba, futhi ushimula ungathululwa ngokhonkolo. Ingxenye engezansi ibekwe ngezitini zobumba njengongqimba oluvikelayo.
