电解铝厂烟气污染的有效治理——提高铝电解槽集气效率

Efficient treatment of fume pollution in the smelters——Improving the hooding efficiency of the Al reduction cells

铝电解槽是电解铝厂大气污染的主要污染源 ,提高电解槽的集气效率能够有效降低含氟电解烟气无组织排放对环境的污染影响 ,通过电解槽密团技术现状与问题的分析 ,从而提出提高电解槽集气效率的改进措施。

Aluminum reduction pots are the major source of airpollution in the aluminum smelter. Byimproving the fume gas collecting efficiency for the reduction pots, it is possible to reduce the impact of fluoride bearing gas irregularly emitted on the environment. Through analysis for the pot hooding technology in respect to the status quo and the problem existed, to come up with an improvenent measure for the gas collecting efficiency over the potline.
