However, when the electrolytic cell is subjected to slotting operations such as pole changing and aluminum tapping, the smoke gas amount is greatly increased and is about 2-4 times of the smoke gas amount during closed production of the electrolytic cell. Under the condition, if the gas collection amount is not increased, the tail end electrolytic cell smoke cannot be ensured not to leak, the gas collection efficiency cannot be ensured, and the unorganized emission of an electrolytic workshop is greatly increased. If the whole system is designed according to the smoke volume of the slotting operation, the system needs to provide twice air volume, the whole system is enlarged, the whole system needs to be comprehensively transformed, and the system construction cost and the operation cost are directly and greatly increased. Therefore, there is a need to develop a power double flue pipe configuration method for an electrolytic cell workshop to reduce the unorganized emission during the slotting operation of the electrolytic cell. When the electrolytic cell is subjected to slotting operation, the gas collection efficiency is increased for the electrolytic cell subjected to slotting operation, and the smoke balance of the surrounding electrolytic cells is not influenced. The gas collection efficiency of the electrolytic cell is ensured, the reconstruction cost is reduced, the energy is saved, the construction speed is accelerated, and the influence on the original system is reduced as much as possible.
