[0002] In the whole process of titanium sponge production, magnesium electrolysis is one of the main processes. This process is to electrolyze the by-product magnesium chloride obtained by reducing titanium sponge through an electrolytic cell to obtain metallic magnesium and chlorine. The metallic magnesium is used for the reduction of titanium sponge, and the chlorine is used for the chlorination production of titanium tetrachloride. Each electrolytic cell has only one chlorine channel. From the current production technology, this channel is narrow and often blocked, affecting the life and output of the electrolytic cell. With the use of the electrolytic cell, the chlorine channel is seriously blocked, and an external chlorine auxiliary pipeline must be added to ensure the smooth flow of chlorine, which poses a great safety hazard. To this end, in response to the above problems, a high-efficiency magnesium electrolysis anode structure is designed to better meet the actual use needs. Utility Model Content
