Abstract
The utility model relates to a magnesium chloride electrolytic cell. A plurality of independent carbon electrodes (4) are equidistantly inserted into an electrolytic chamber formed between a single-set cathode (2) and a single-set anode (3) of the magnesium chloride electrolytic cell; the distances between the independent electrodes (4) and the cathode (2) as well as the anode (3) and the distances among the independent electrodes (4) have to be kept to be more than or equal to 5+/-0.5mm; and the quantity of the independent carbon electrode(s) (4) equidistantly inserted into the electrolytic chamber formed between the single-set cathode (2) and the single-set anode (3) of the magnesium chloride electrolytic cell ranges from one to five. By adopting the structure, the production capacity of the single-electrode electrolytic cell can be theoretically doubled and redoubled under the same current, the production capacity of a single groove can be greatly improved, and the investments of an aluminum bus, an electrolytic cell and a factory can be reduced.
Description
Technical field the utility model relates to a kind of electrolysis of magnesium chloride and extracts the magnesium field, specifically is exactly the electrolyzer that a kind of electrolytic process is produced magnesium.
Background technology magnesium is 21 century " green material ", be widely used in Aeronautics and Astronautics, communications and transportation, electronic communication field and metallic reducing agent with its excellent performance, cause the great attention of various countries, the exploitation of magnesium alloy materials and application also become the field of giving priority to of novel material, and the production of MAGNESIUM METAL causes widely to be paid close attention to.
The process for extracting of MAGNESIUM METAL mainly contains fused salt electrolysis and two kinds of technologies of metallothermics, and wherein fused salt electrolysis technology is used more extensive in magnesium titanium associated enterprises.At present, domestic enterprise all adopts tradition to include partition board electrolytic cell and no partition board electrolytic cell in interior monopolar cell technology, its primary structure is to place many group yin, yang electrodes in same electrolyzer side by side, every group of yin, yang electrode forms a tank room, is relation in parallel between each tank room in same electrolyzer.Sodium-chlor-Repone K-the melting salt of calcium chloride system that magnesium chloride weight percent in the electrolyzer is accounted for 10%-20% is heated to about 700 ℃ and carries out electrolysis with direct current, and negative electrode generates liquid magnesium, and anode generates chlorine.Because the density of MAGNESIUM METAL is lower than melting salt, the MAGNESIUM METAL of generation can float over liquid level, and MAGNESIUM METAL is extracted in electrolysis out.The chlorine emersion electrolyte levels that anode generates produces negative pressure by the chlorine press and extracts out.
This monopolar cell is generally by increase electrolyzer volume, and increase anode and cathode group number realizes increasing single groove production capacity in same electrolyzer, but the anode and cathode group number in this electrolyzer can not be too much, otherwise can cause electrolytic process heat imbalance.This monopolar cell list groove production capacity is low, is generally about 1t/d, and current efficiency is low, and the energy consumption height is 15000-17000kWh/t, and the space effective rate of utilization of electrolyzer is low, and the investment that causes aluminium busbar, electrolyzer and factory building to take up an area of is big, and production cost is higher.
The summary of the invention the purpose of this utility model is exactly for the solution the deficiencies in the prior art, and a kind of electrolysis of magnesium chloride groove is provided, and it can be so that electrolysis of magnesium chloride technique device list groove production capacity increases, energy consumption reduces, less investment.
For realizing technical purpose, the technical scheme that the utility model is taked is: a kind of electrolysis of magnesium chloride groove, it is characterized in that organizing equidistant insertion carbonaceous absolute electrode in the tank room that forms between negative electrode and the anode at the list of electrolysis of magnesium chloride groove, former tank room is divided into a plurality of tank rooms, this absolute electrode is an anode near one side of cathode electrode, the other side is a negative electrode, does not need to be connected with direct current.
Characteristics of the present utility model are that also the distance between absolute electrode and negative electrode and anode and absolute electrode must keep 〉=5 ± 0.5mm.
Characteristics of the present utility model are that also the number of organizing equidistant insertion carbonaceous absolute electrode in the tank room that forms between negative electrode and the anode at the list of electrolysis of magnesium chloride groove is 1-5.
The invention has the beneficial effects as follows: adopt this electrolyzer, in theory, under same electric current, the throughput of monopolar cell can be improved many times.Can improve electrolyzer space effective rate of utilization, improve single groove production capacity greatly, reduce the investment that aluminium busbar, electrolyzer and factory building take up an area of.
