Powdery lime slurrying system for Bayer process red mud dealkalization
The invention relates to a powdery lime slurrying system aiming at Bayer process red mud dealkalization, which belongs to the technical field of aluminum oxide production and comprises a lime bin, slurrying reaction equipment, a buffer tank, a settling tank and an overflow tank, a discharging pipe of the metering conveying device and a slurrying water inlet pipe are both connected with the feeding end of the slurrying reaction device, the slurrying reaction device is connected with the buffer tank, the buffer tank is connected with the settling tank through a vertical buffer pump arranged on the top, and the settling tank is connected with the overflow tank through an overflow pipe. The method solves the problems that in the Bayer process aluminum oxide production process, after the red mud dealkalization procedure is added, the dosage of lime milk is sharply increased, and the treatment capacity of a traditional ashing system is insufficient, meanwhile, graded utilization of high-concentration lime milk and low-concentration lime milk is achieved, and the production efficiency of lime milk preparation is improved.
一种针对拜耳法赤泥脱碱的粉状石灰浆化系统，属于氧化铝生产技术领域，包括石灰仓、浆化反应设备、缓冲槽、沉降槽、溢流槽，所述石灰仓的出料端经螺旋闸门与计量输送设备相连，计量输送设备的出料与浆化水进水管道均与浆化反应设备的进料端相连，浆化反应设备与缓冲槽相连，缓冲槽经顶部设置的立式缓冲泵与沉降槽相连，沉降槽通过溢流管与溢流槽相连。本发明解决了拜耳法氧化铝生产过程中，增加赤泥脱碱工序后所带来的石灰乳用量剧增，传统化灰系统处理能力不足的问题，同时实现高低浓度石灰乳的分级利用，提高石灰乳制备的生产效率。
