Two-section type system for suspension calcination of powdery low-speed lime
The invention discloses a two-stage suspension calcination system for powdery low-speed lime. The two-stage suspension calcination system comprises a first-stage suspension preheating light burning unit, a second-stage re-burning unit and a suspension cooling unit, the first-section suspension preheating light burning unit comprises a multi-stage cyclone separator and a decomposing furnace; the multistage cyclone separator preheats the limestone raw material in a suspension manner, and the decomposing furnace performs high-temperature light burning on the preheated limestone raw material to obtain calcium oxide; the second-stage re-burning unit is used for re-burning calcium oxide obtained by high-temperature light burning or calcium oxide mixed with partially preheated limestone; and the suspension cooling unit is used for cooling the reburnt material to obtain the low-speed lime. Through suspension preheating, suspension light burning, re-burning and suspension cooling, the low-speed lime production energy consumption is remarkably reduced, the low-speed lime calcining time is shortened, the product quality is improved, and low-cost and high-efficiency production of the low-speed lime is realized.
本发明公开了一种两段式悬浮煅烧粉状慢速石灰的系统，包括一段悬浮预热轻烧单元，二段重烧单元和悬浮冷却单元；所述一段悬浮预热轻烧单元包括多级旋风分离器和分解炉；所述多级旋风分离器对石灰石原料悬浮预热，所述分解炉对预热的石灰石原料进行高温轻烧得到氧化钙；所述二段重烧单元对高温轻烧得到的氧化钙或混有部分预热的石灰石的氧化钙进行重烧；所述悬浮冷却单元对重烧后的物料进行冷却得到慢速石灰。本发明通过悬浮预热、悬浮轻烧、重烧及悬浮冷却，显著降低了慢速石灰生产能耗，缩短了慢速石灰煅烧时间，提高了产品质量，实现了慢速石灰的低成本、高效率生产。
