铝电解预焙阳极沥青烟净化技术研究进展

随着我国经济建设的高速发展,建筑行业和日化产业都得到了长足的发展,带动之下,电解铝行业也发展迅速,这也在某种程度上推动了炭素企业的快速发展。但同时一些问题也随之尖锐化,诸如沥青烟的排放,一直是企业和国家相关部门亟待解决的问题。本文对沥青烟的构成和国内外对沥青烟的净化技术进行了阐述,从而对铝电解预焙阳极沥青烟净化技术的发展做了技术性展望,以期能够对国内这一技术的发展有所助益。

Research progress in purification technology of pitch fume from prebaked anode in aluminum electrolysis

With the rapid development of China's economic construction,the construction industry and the daily chemical industry have achieved considerable development,driven by the rapid development of electrolytic aluminum industry,which also to some extent promotes the rapid development of carbon enterprises.But at the same time,some problems are also sharpened,such as the emission of asphalt smoke,which has always been an urgent problem to be solved by enterprises and relevant national departments.In this paper,the composition of asphalt fume and the purification technology of asphalt fume at home and abroad are described,so as to make a technical prospect for the development of aluminum electrolysis prebaked anode asphalt fume purification technology,in order to be helpful for the development of this technology in China.
