Sustainable Mining and Metallurgy

Using FLUENT to simulate the flue gas flow field and temperature field of electrolytic cell, and combined with the design experience, the multi-stage equal air suction and gas collection flue structure and double flues technology suitable for SY series electrolytic cell were successfully developed. The structure of multi-stage air suction and gas collection flue adopts the form of upper flue gas collection. While strengthening the gas collection effect and balancing the wind pressure distribution in the tank chamber, it can greatly reduce the smoke exhaust volume of the electrolytic tank and reduce the flue resistance by 17%~27%. The double flues technology is improved on the schemes of HYDRO and SOLIOS. The main and auxiliary flues are provided with negative pressure power by the purification fan. During the slotting operation, the main and auxiliary smoke flues collect gas at the same time, and the amount of flue gas can be instantaneously increased by 2~3 times, so as to effectively control the unorganized emission of pollutants in the electrolysis workshop and achieve the purpose of energy conservation and emission reduction.
