Изобретение относитс к технологии цемента , в частности к производству цементного клинкера.The invention relates to cement technology, in particular to the production of cement clinker.
Известен способ производства цементного клинкера путем факельного сжигани топ лива в рабочем объеме вращающейс печи и в слое материала по ее длине и подачи части сырьевого материала и минеральных добавок отдельно от основной массы материала вдуванием с гор чего конца печи.A known method for producing cement clinker by flaring the fuel in the working volume of the rotary kiln and in the material layer along its length and feeding part of the raw material and mineral additives separately from the main mass of the material by blowing from the hot end of the kiln.
Однако вдуваемый с гор чего конца печи материал неравномерно присаживаетс к обжигаемому в печи материалу, привод к волнообразному движению последнего; резко ухудщаетс видимость в зоне спекани , что затрудн ет управление печью, снижаетс теплонапр жение в зоне спекани .However, the material blown from the hot end of the furnace unevenly sits on the material to be calcined in the furnace, resulting in a wave-like movement of the latter; visibility in the sintering zone is sharply deteriorating, which makes it difficult to control the furnace, and the heat stress in the sintering zone decreases.
Целью изобретени вл етс стабилизаци режима обжига, дл чего часть сырьевого материала и добавки ввод т в слой мтерила совместно со сжигаемым по длине печи топливом.The aim of the invention is to stabilize the firing mode, for which part of the raw material and the additive is introduced into the layer of material with the fuel burned along the kiln.
Сущность предлагаемого способа заключаетс в том, что вводимое отдельно от осThe essence of the proposed method lies in the fact that the input separately from
новной массы материала вещество в тонкодисперсном состо нии с помощью специальных распределительных форсуночных устройств подаетс в слой материала по длине вращающейс печи вместе со сжигаемым на данном участке печи технологическим топливом . В результате присадка материала сосредотачиваетс в одном участке, он хорошо перемешиваетс , видимость в печи не ухудщаетс , дополнительное введение материала не отражаетс на теплонапр жении зоны спекани .A material in a finely dispersed state with the help of special distribution nozzle devices is fed into the material layer along the length of the rotary kiln together with the process fuel burned in this area of the kiln. As a result, the additive of the material is concentrated in one area, it is well mixed, the visibility in the furnace does not deteriorate, the additional introduction of material does not reflect on the heat stress of the sintering zone.
Предлагаемый способ позвол ет также вводить специальные минерализующие добавки непосредственно в те зоны печи, где их воздействие наиболее значительно, например, ТбрОз зону декарбонизации.The proposed method also allows the introduction of special mineralizing additives directly into those zones of the furnace where their effect is most significant, for example, TbO3 decarbonization zone.
