Ukomiswa, ukufudumeza kanye nokugcinwa kwemishini kasimende kuhhavini

I-castable eqinile noma eyomisiwe isenawo amanzi asele ngokomzimba namakhemikhali, bese ishiselwa ku-300 ℃ ukuze ihwamuke futhi ikhiphe amanzi emzimbeni, futhi wonke amanzi azokhishwa. Ngenxa yokuthi i-castable inesakhiwo esiminyene, izinga lokushisa kufanele lihambe kancane ukuze kugwenywe ukunyuka okusheshayo kwezinga lokushisa. Ukucindezeleka okubangelwa ukuhwamuka okusheshayo komswakama ophezulu kanye nomswakama kubangela ukulimala kwe-castable.

Isistimu yokomisa nokushisa yesistimu yeziko ngezinye izikhathi ayikwazi ukuhlangabezana nezidingo zokomisa ze-preheater kanye ne-calciner (i-cooler ye-grate, i-hood hood kanye ne-tertiary air duct ihlangabezana nesistimu yokomisa nokushisa yesistimu yeziko, futhi ayifakwanga ngokuhlukana), ngakho-ke, Isistimu yokushisa yokubhaka yesistimu yeziko okukhulunywe ngezansi kufanele ihlanganiswe nezidingo zalesi sigaba. Uma izinga lokushisa lesistimu yeziko lifinyelela ku-600 ° C (kuncike ekushiseni kwegesi yokukhipha emsileni womlilo), i-preheater eyinhloko ayihlangabezani nezidingo zokomisa, futhi isikhathi sokugcina ukushisa kwesistimu yokushisa ku-600 ° C kufanele. kwandiswe.

Isikhathi sokuphulukisa seqeqebana lokugcina lokuphonswa kwe-refractory asikho ngaphansi kwama-24h ekushiseni okungaba ngu-25°C (kuma-castable usimende aphansi, isikhathi sokuphulukisa kufanele sinwetshwe siye ku-48h ngokufanele). Ngemuva kokuthi i-castable ithole amandla athile, susa i-formwork nokusekelwa. Ukubhaka kungenziwa ngemva kokumiswa kwamahora angu-24. Uma izinga lokushisa lokwelapha liphansi kakhulu, isikhathi sokuphulukisa sidinga ukunwetshwa.

Thatha izinga lokushisa le-exhaust gas emsileni wokushisa njengezinga elijwayelekile, futhi usebenzise izinga lokushisa elingu-15°C/h lize lifinyelele ku-200°C, bese uligcina amahora angu-12.

Phakamisa izinga lokushisa libe ngu-400°C ngezinga lokushisa elingu-25°C/h, futhi ugcine izinga lokushisa lingekho ngaphansi kuka-6h.

Yenyusa izinga lokushisa libe ngu-600°C futhi ugcine izinga lokushisa lingekho ngaphansi kuka-6h. Lezi zimo ezimbili ezilandelayo yizimo ezidingekayo nezanele zokubhaka i-calciner kanye nohlelo lwe-preheater:

Lapho izinga lokushisa le-refractory castable emgodini wokuthela we-cyclone preheater eduze nesembozo se-silicon lifinyelela ku-100 ℃, isikhathi sokumisa akufanele sibe ngaphansi kuka-24h.

Emnyango womgodi we-preheater ye-cyclone yezinga lokuqala, kwasetshenziswa ucezu lwengilazi oluhlanzekile ukuze kuxhunywe igesi ephumayo, futhi akukho ukuvuza komswakamo engilazini okubonwe. Isikhathi sokugcina ukushisa sasingu-6 amahora.
