摘要
在铝电解生产工艺中,电解槽排放的烟气中蕴藏着大量的低温余热热能。以有机朗肯循环为基础,以水、有机物为传递工质,将此部分热能转化为可驱动风机的动能,实现对低温余热热能能质的提高并有效利用。同时,本文以某800kt/a铝电解工程为例,对铝电解低温余热利用方案展开研究与讨论。
During aluminum reduction, there are a large number of low temperature waste heats from exhausting fume. Based on Organic Rankine Cycle, this part of heat energy could be changed into kinetic energy for the fume fans by the water,organic matter for the working medium,so the low temperature waste heat can be effectively utilized. As an example of an aluminum reduction project of 800kt/a, the utilization scheme of low temperature waste heat from aluminum reduction is discussed in this paper.
