预焙阳极生产过程收尘粉回收利用技术的开发与应用

针对预焙阳极生产过程中产生的收尘粉,以循环经济3R原则为指导思想,对各点收尘粉的性能进行比较筛选,确定适宜炭生产使用的收尘粉;根据空气动力学和固体颗粒稀相输送原理,成功开发出预焙阳极生产过程收尘回收利用技术,并创新收尘粉进入球磨机给料方式,消除因外来收尘粉对球磨粉的粒度影响,使球磨粉-0.074 mm的纯度稳定控制在68%～75%,实现球磨粉纯度的稳定控制。

The Development and Application for the Technology of Recycle and Reuse of Collected Dust in the Prebaked Anode Production Process

For the collected dust produced from the prebaked anode production process,it is determined that some of the dust collection powder is suitable for carbon production,which is according to the 3R principle guiding ideology of circular economy,as well as the comparison and selection according to the performance of collected dust from each dust collection point;based on aerodynamics and solid particle diluted phase conveying principle,the technology of recycle and reuse of dust from prebaked anode production h...
