Aluminum electrolyzer energy flow optimization and intelligent control technology to achieve industrialization
On April 6, according to the School of Materials Science and Engineering of Zhengzhou University, Professor Liang Xuemin of the institute, Zhengzhou Light Metallurgy Technology Co.
, Ltd.
, Henan Zhongfu Industrial Co.
, Ltd.
, etc.
jointly undertaken the Zhengzhou collaborative innovation major project - aluminum electrolyzer energy flow optimization and intelligent control technology development, has completed basic test research and industrial system development integration, the first system in Zhongfu aluminum officially put into industrial operation
.
Since 2008, Liang Xuemin's team has begun to explore in the field of "energy saving at the output end" of electrolytic aluminum, and has successively broken through technical problems such as the thermal characteristics and energy flow optimization theory of aluminum electrolyzers, and the efficient aggregation of tank heat dissipation, and successfully developed industrial electrolyzer heat collectors and energy flow intelligent adjustment equipment
with independent intellectual property rights.
After the system is officially put into operation, the recovered heat energy, which accounts for about 10% of the total energy consumption of the electrolyzer, will be sent to the first station
of the city heating system through a 3km long thermal pipeline.
Liang Xuemin said that the project team will carry out further research to obtain the best thermal characteristics of the electrolyser through energy flow optimization, explore the extreme optimization process of electrolyzer operation, and further tap the potential of "energy saving at the input end" of
aluminum electrolysis.
At the same time, establish a new concept of aluminum electrolysis "output end energy saving", develop the application field of electrolytic aluminum "output end energy saving" to expand to industrial heat network, thermal power generation system, large industrial refrigeration and other large industrial user systems interconnection new technology and complete sets of industrial systems, in order to finally achieve the overall goal
of electrolytic aluminum energy saving 8%~10%.
