Magnesium electrolyzer assembly line and method of merging single cell operation into assembly line

Abstract

The invention belongs to the technical field of magnesium electrolysis and discloses a magnesium electrolytic cell production line and a method of incorporating a singly-operating cell into the production line. The production line comprises a head cell, electrolytic cells and a separation cell which are sequentially connected through a connecting channel. The multiple electrolytic cells are connected in series. A segment of bypass channel is arranged between the two ends of each electrolytic cell. The two ends of each bypass channel are connected with the connecting channel. A pneumatic pump is arranged in the separation cell. The pneumatic pump is used for conveying an electrolyte melt in the separation cell to the head cell to form the circulating production line. One bypass channel is arranged between the two ends of each electrolytic cell. When the single electrolytic cell needs to be incorporated into the production line, the corresponding bypass channel can play a role in auxiliary adjustment, the production line is adopted, in combination with proper adjustment, operations such as feeding and magnesium outlet can be reduced before the single electrolytic cell is not completely incorporated into the production line, meanwhile the operation of incorporating the single cell into the production line is easy, safe and reliable, and the situations that the melt leaks, and the cell condition is abnormal can be avoided.

Description

technical field [0001] The invention relates to the technical field of magnesium electrolysis, in particular to a magnesium electrolytic cell assembly line and a method for merging single cell operation into the assembly line. Background technique [0002] In the production of sponge titanium, in order to realize the cycle of magnesium and chlorine, it is necessary to build a magnesium electrolysis process. The magnesium chloride produced in the reduction process is used as the raw material for electrolysis, and the magnesium produced by electrolysis is used to reduce the production of sponge titanium. The assembly line magnesium electrolysis process generally includes 14 to 30 electrolyzers, and the assembly line is divided into different stages according to the number of electrolyzers started and running. When the magnesium electrolysis line with a certain number of electrolytic cells has been running, after restarting the electrolytic cell, in order to prevent the newly s...
