目前,中铝山西分公司氧化铝一分厂现有4台混料式机械化竖窑,生产石灰供氧化铝生产配料及制取石灰乳,产生的CO2用于碳酸化分解。因此石灰炉在氧化铝生产中是非常重要的设备,其生石灰的产量、质量及出口CO2的浓度对后续几个关键工序产生直接影响;而石灰炉本身也是耗能量很大的设备,所以对其生产与工艺过程进行全息仿真、监测与有效控制,无论对氧化铝生产的优质高产还是对节能环保均具有重要意义。
At present, a branch of Alumina of Chinalco Shanxi Branch currently has 4 sets of mixed mechanized shaft kilns, which produces lime for the production of alumina and the production of lime milk, and produces CO2 for carbonation and decomposition. Therefore, the lime stove is a very important equipment in the alumina production. The output, quality of the lime and the CO2 concentration in the outlet have a direct impact on the following key processes. The lime stove itself is also a device that consumes a lot of energy. Therefore, Production and process of holographic simulation, monitoring and effective control, both for the production of high-quality aluminum oxide production or energy saving are of great significance.
