Embodiment 1
[0028] Please see attached figure 2 The basic components of a high-efficiency dual-magnesium-collecting chamber electrolyzer structure are an anode 1, a cathode 2, an electrolytic chamber 3 and two magnesium-collecting chambers 4. The distance between the cathode plate and the anode plate is 0.07m, the cathode and the anode are inserted into the magnesium electrolytic cell from the top of the electrolytic cell, the width and height of the cathode and the anode are the same, the width is 1m, the height is 2.2m, and the thickness of the cathode plate is 0.05 m, the thickness of the anode plate is 0.15m.
[0029] Through the analysis of electric field, thermal field, magnetic field and flow field, the thermal balance of the upward inserted cathode magnesium electrolytic cell is good,
[0030] The electrolyte temperature is 700°C, the electrolyte flow state is good, and the separation rate of metal magnesium is greatly improved. The flow field distribution of the electrolyzer i...

Abstract
The invention relates to a magnesium electrolytic cell with high current efficiency and double magnesium collecting chambers, which is characterized in that the magnesium electrolytic cell comprises a cathode plate, an anode plate and a magnesium collecting chamber, and the number of the magnesium collecting chambers is two, which are respectively arranged on the cathode plate and the magnesium collecting chamber. On both sides of the anode plate, and the two magnesium collection chambers are symmetrically distributed. The invention changes the structure of the traditional magnesium electrolytic cell, adopts two symmetrical magnesium collecting chambers, and adopts the method of inserting the cathode and the anode up or down between the two magnesium collecting chambers. The structure changes the flow condition of the electrolyte in the magnesium electrolyzer, makes full use of the flow characteristics of the electrolyte, and improves the separation efficiency of metal magnesium. Compared with the original cell type, the metal magnesium separation efficiency of the high-efficiency double magnesium collecting chamber electrolytic cell is greatly improved, and the effect is obvious.
Description
【Technical field】 [0001] The invention relates to the technical field of electrolytic cells, in particular to a magnesium electrolytic cell with high current efficiency and double magnesium collecting chambers. 【Background technique】 [0002] Magnesium is the lightest non-ferrous metal, which can form high-strength alloys with other metals well, and its continuous improvement of castability makes it more and more widely used, and it is a beneficial supplement to traditional aluminum alloys. In the United States, magnesium alloys have experienced explosive growth in the fields of consumer electronics, automobiles, and medical care, and are likely to replace traditional alloys such as aluminum alloys. Magnesium is not only expected as a lightweight material, but also as an electrode construction material for magnesium fuel cells, which has important applications in the battery industry. [0003] China is a country with large magnesium resources and a large producer of magnesi...
