Suspension calcining system with CO2 partial pressure reducing function and method for preparing high-activity lime by suspension calcining system
The invention discloses a suspension calcination system with a CO2 partial pressure reducing function and a method for preparing high-activity lime by the suspension calcination system, and belongs to the technical field of limestone calcination. The system comprises a pretreatment unit, a calcination unit, a cooling unit, a dust removal unit, a CO2 treatment unit and a product bin; the method for preparing the high-activity lime comprises the following steps: crushing limestone raw ore, adding the crushed limestone powder into a limestone powder feeding bin, feeding the limestone powder into a cyclone preheater for three-stage preheating, adding the limestone powder into a suspension calcining furnace for calcining, and introducing air into the bottom of the calcining furnace in the calcining process to ensure that the powder is always in a suspension state; and feeding the calcined powder into a cyclone cooler for three-stage cooling to obtain the high-activity lime. In the process of preparing the high-activity lime, the powder is heated more uniformly, the heat transfer efficiency is higher, CO2 generated by decomposition of flowing gas is discharged in time, separation is conducted through the CO2 treatment equipment, limestone decomposition moves in the forward direction, the decomposition speed is increased, and the decomposition efficiency is improved.
一种具有降低CO2分压功能的悬浮煅烧系统及其制备高活性石灰的方法，属于石灰石的煅烧技术领域，其系统包括预处理单元、煅烧单元、冷却单元、除尘单元、CO2处理单元及产品仓；制备高活性石灰的步骤如下：将石灰石原矿破碎后，加入石灰石粉料给料仓，给入旋风预热器进行三级预热，加入到悬浮煅烧炉中进行煅烧，煅烧过程中在煅烧炉底部通入空气，确保粉料始终处于悬浮状态；经过煅烧后的粉料送入旋风冷却器进行三级冷却，得到的高活性石灰。本申请在制备高活性石灰的过程中，粉料受热更均匀，传热效率更高，流动的气体及时排出分解产生的CO2，通过CO2处理设备进行分离，使石灰石分解向正向移动，加快分解速度，提高分解效率。
