Baffleless magnesium electrolytic cell and use method thereof

Abstract

The invention discloses a baffleless magnesium electrolytic cell, and is used for solving the problems that a conventional baffleless magnesium electrolytic cell has relatively small capacity, is not applicable to production of larger metal magnesium plants, the current efficiency is not high and the electrolytic magnesium generation energy consumption is larger. A magnesium collecting chamber and electrolytic chambers are arranged in the electrolytic cell, a gas collecting cover is arranged on the upper part of the magnesium collecting chamber, and a cell lid is arranged on the upper ends of the electrolytic chambers. The magnesium collecting chamber is arranged at the middle of the electrolytic cell, two sides of the magnesium collecting chamber are each provided with the electrolytic chamber, separating walls are arranged between the magnesium collecting chamber and the electrolytic chambers, each separating wall is provided with melt communication passages, and the cell lid at the upper parts of the electrolytic chambers is also provided with chlorine gas discharge outlets communicated with the electrolytic chambers. The baffleless magnesium electrolytic cell is used for electrolytic production of magnesium.

Description

technical field [0001] The invention relates to an electrolytic cell, in particular to a magnesium electrolytic cell without a partition in which a magnesium collecting chamber is arranged in the middle of the electrolytic cell. Background technique [0002] Electrolyzer is one of the key equipments for electrolytic magnesium smelting. Its structure and performance directly affect the product cost, energy consumption and other technical indicators. At present, the electrolytic cells used in the industrial production of magnesium metal are divided into three types: cells with partitions, cells without partitions, and multi-pole cells. The multi-pole tank is mainly used in the magnesium electrolysis system for the production of sponge titanium. It is characterized by low DC power consumption, but has high quality requirements for the electrolysis raw material-magnesium chloride. There are disadvantages such as high power consumption, low concentration of chlorine gas produced...
