Ziziphi isitena esichasayo izinto zokulahla izitshisi zenkunkuma?

Izitshisi zenkunkuma zohlulwe zibe: izitshisi zenkunkuma ezomeleleyo zikamasipala, isiqhumiso esiphakathi, isitshizi sohlobo lwegrate, isitshisi segesi yenkunkuma, isitshisi sokutshisa ibhedi, irotary kiln-type incinerator industrial, uhlobo lwe grate-type incinerator incinerator.

Ku

Ngenxa yokuba kukho iintlobo ezininzi zenkunkuma ezingenako ukuhlelwa ngokupheleleyo, ixabiso le-caloric lenkunkuma likwahlukile. Ukuze kuqinisekiswe ukuba i-incinerator yenkunkuma igcina ukusebenza kakuhle phantsi kwexesha elide lokushisa okuphezulu, kuyimfuneko ukuqwalasela ukukhethwa kwezinto ezichasayo ezivela kwiinkalo ezininzi. Ngokukodwa izitena ze-silicon carbide. Izinto ezichithwayo ikakhulu zisekwe kudongwe, iiplastiki eziphezulu zealumina, ezisekwe ngodongwe, kunye nesilicon carbide-based castables. Ngenxa yokubola okuphezulu kwezinto zokutshisa inkunkuma, ukusetyenziswa kwezinto ezichithwayo zihlala zivela. Ukusetyenziswa kwe-silicon carbide castables kunye ne-phosphates edityaniswe ne-high-alumina castables iyanda ngokuthe ngcembe ngenxa yokuba ezi zimbini ezinqabileyo zinokuxhathisa okulungileyo.

Isiseko sokukhethwa kwezinto ezichasayo: ii-incinerators ezahlukeneyo zenkunkuma zineemeko ezahlukeneyo zokusebenza, kunye namaqondo okushisa ahlukeneyo angaphakathi afuna iimpawu ezahlukeneyo zezinto eziphikisayo. Ke ngoko, izinto eziphikisayo ezineempawu ezahlukeneyo kufuneka zikhethwe ngokwendawo yazo yokusebenza kunye nobushushu bokusebenzisa. Ubushushu bokusebenza kwesitshisi senkunkuma yi-1200℃-1400℃. Irhasi igqwesa kakhulu kwimathiriyeli ye-refractory ngexesha lokutshiswa, kwaye umzantsi wesithando somlilo, i-propellers, kunye neendonga ezisecaleni zigugile kakhulu kwaye zinefuthe. Ngoko ke, ukhetho lwe-lining ephezulu luya kuqhubeka nokuhlaziywa.

Khetha izinto ezichasayo ngokwendawo yokusebenza. Kwinxalenye yegalelo le-incinerator yenkunkuma, ekubeni igalelo kunye nokuwa kwenkunkuma kufuneka idibane nezinto eziphathekayo, kunye nokushisa kwe-port input isoloko itshintsha, i-refractory iyadingeka ukuba ibe nokumelana nokunxiba kakuhle kunye nokuxhatshazwa kwe-thermal. Ukuzinza, izitena zodongwe zingasetyenziswa.

Kwigumbi lokumisa kunye negumbi lokutshisa i-incinerator yenkunkuma, inkunkuma kunye ne-furnace lining idibanisa ngokuthe ngqo kumaqondo aphezulu. Ngakolunye uhlangothi, i-slag iya kubambelela kwisithando somlilo, kwaye ngakolunye uhlangothi, ukungcola kuya kuhlasela umbane wesithando somlilo. Ngexesha elifanayo, igalelo lenkunkuma ngokuqinisekileyo liya kubangela utshintsho lobushushu. Ke ngoko, izinto eziphikisayo ziyafuneka ukuba zinganyangeki kuphela, zikwazi ukumelana nokugqwala, kwaye kunzima ukubambelela, kodwa zikwazi ukumelana ne-alkali kunye ne-oxidation-resistant. Ngokuqhelekileyo, izitena zodongwe, izitena eziphezulu ze-alumina, izitena ze-SiC, i-castables kunye neeplastiki zisetyenziswa.

Khetha izinto ezichasayo ngokweqondo lobushushu bokusetyenziswa, izitshisi zenkunkuma ezahlukeneyo, iindawo ezahlukeneyo zokusetyenziswa, kunye namaqondo obushushu okusebenzisa ahlukeneyo: ubushushu bokusetyenziswa kophahla, iindonga ezisecaleni, kunye nezitshisi zegumbi lokutsha yi-1000-1400, kunye ne-refractoriness ye-1750-1790. inokukhethwa. Izitena eziphezulu ze-alumina kunye nezitena zodongwe, iiplastiki ezine-refractoriness ye-1750-1790 nazo zingasetyenziswa.

Iimfuno zemathiriyeli ye-refractory kufuneka zibe nala manqaku alandelayo:

1. Sebenzisa amandla aphezulu kunye neemveliso ezingagugiyo ukumelana nokunxiba kunye nokuhamba komoya okunamandla;

2. Kufuneka ibe nokumelana ne-asidi kunye nokuzinza ukuxhathisa ukubola kwe-asidi;

3. Ukutshatyalaliswa kwe-thermal kwakhona yinto ebalulekileyo engenakuhoywa;

Okwesine, kufuneka ibe nokukhukuliseka kwe-CO ukukhusela izinto ze-lining ekuqhekekeni;

Okwesihlanu, ukukhethwa kwezinto zokugquma, ngokweemeko ezahlukeneyo, khetha izinto zokukhanyisa ukukhanya ezifanelekileyo ngakumbi kwinxalenye nganye.
