In the development process, the project applied for 11 patents, of which 6 were authorized and 5 received.
The main contents and innovations of this project are: asymmetrical six-terminal power supply for the busbar; optimized design of the magnetic field to make the operation of the electrolytic cell stable; new design of “system heat balance†using the simulation of heat balance of the electrolyzer body and plant ventilation simulation The method has achieved good cell heat balance and plant ventilation design effects; the use of narrow processing surface, tank shell plus fins, large spacing cradle structure, to obtain a small amount of material, compact structure, tank shell deformation is small, thermal stability The good results; The development of three-stage ventilation technology is conducive to improving gas gathering efficiency and improving the environment.
The achievements in the construction of the Province of Investment, with good technical and economic indicators, have significant economic and social benefits.
The results have been used in the 268kt/a new construction project of Lanzhou Aluminum Industry Co., Ltd., and this technology is used for bidding on multiple electrolytic aluminum projects in Saudi Arabia and Iran. Has a good promotion and use value.
