提出自焙槽的改造方向应是自焙槽改为预焙槽。改为预焙槽后,可彻底消除铝厂的沥青烟害,有利于采用干法净化的方法解决铝厂的环境保护问题。同时可取得节能降耗,提高机械化、自动化水平,降低工人的劳动强度,实现文明生产等明显的经济效益和社会效益。该文还提出了60～75KA自焙槽改造为预焙槽的方案。 It is suggested that the reforming direction of self-baking trough should be changed from self-baking trough to pre-baking trough. After changing to the prebaked cell, the bitumen smoke in the aluminum plant can be completely eliminated, which is good for the dry purification method to solve the environmental protection problem of the aluminum plant. At the same time, it can achieve obvious economic and social benefits such as saving energy and reducing consumption, raising the level of mechanization and automation, reducing the labor intensity of workers and realizing civilized production. The article also proposed a 60 ~ 75KA self-baking trough into pre-baked tank program.
