Abstract

Sposób wytwarzania nisko reaktywnego wapna, charakteryzuje się tym, że kamień wapienny poddaje procesowi wypalania w hybrydowym piecu dwuszybowym do wypalania wapna w cyklach w jednym szybie, podczas którego gorące powietrze powstałe przy grzaniu przekazywane jest do drugiego szybu w celu wstępnego podgrzania kamienia wapiennego, po czym otrzymane w ten sposób wapno o wysokiej reaktywności, w dolnej części pieca poddaje się grzaniu palnikami gazowymi skierowanymi poziomo do szybu pieca, po czym otrzymane w ten sposób wapno o niskiej reaktywności poddaje procesowi studzenia za pomocą powietrza wtłaczanego od dołu pieca, które zarazem wykorzystywane jest do spalania gazu, przy czym spaliny wytwarzane przy wypalaniu gazem ziemnym, zawierające głównie dwutlenek węgla jako produkt kalcynacji i spalania gazu ziemnego, oczyszcza w filtrze workowym i odprowadza do atmosfery, następnie wapno nisko reaktywne podaje się procesowi przesiewania wibracyjnego na przesiewaczu jednopokładowym, separuje na frakcję i poddaje konfekcjonowaniu.The method of producing low-reactive lime is characterized by the fact that limestone is subjected to the firing process in a hybrid double-glass kiln for firing lime in cycles in one shaft, during which hot air generated during heating is transferred to the second shaft in order to preheat the limestone, after which the lime with high reactivity obtained in this way is heated in the lower part of the furnace with gas burners directed horizontally to the furnace shaft, after which the lime with low reactivity obtained in this way is subjected to the cooling process by means of air injected from the bottom of the furnace, which is also used for gas combustion, the flue gas produced during firing with natural gas, containing mainly carbon dioxide as a product of calcination and combustion of natural gas, is purified in a bag filter and discharged into the atmosphere, then low-reactive lime is fed to the screen by vibrating screening single-deck, separates into fraction and subjected to confectioning.
