Description
[technical field]
The present invention relates to cell technologies field, specifically, is a kind of slotting cathode type closing down magnesium electrolysis bath.
[background technology]
Magnesium is the most light non-ferrous metal of one, and because it can be good at forming with other metals the high and alloy that density is little of intensity, its Application Areas is more and more wider.Magnesium not only enjoys expectation in fields such as consumer electronics, automobile, medical treatment as lightweighting materials, also as the electrode constituting material of magnesium fuel cell, has important application at battery industry.
China is MAGNESIUM METAL big producing country, and its production method is mainly based on pyrolysis Pidgeon process.The domestic art electrolysis cells produced for electrolytic process falls behind, output and production efficiency is low, energy consumption is high.And external closing down magnesium electrolysis bath strength of current is large, level of automation is high, and unit surface MAGNESIUM METAL output is high, and power consumption is low.China runs the current efficiency of non-inductive windings closing down magnesium electrolysis bath at present only about 76 ~ 78%, and MAGNESIUM METAL separation rate is low, and whole magnesium eletrolysis industry is huge with external gap.
The present invention is by the magnesium eletrolysis technique of research advanced person, and exploitation has the magnesium eletrolysis gordian technique of China's independent intellectual property right.Cell construction is transformed simultaneously, to improve the MAGNESIUM METAL separation rate of electrolyzer, reduce energy expenditure.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, a kind of slotting cathode type closing down magnesium electrolysis bath is provided.
The object of the invention is to be achieved through the following technical solutions:
One inserts cathode type closing down magnesium electrolysis bath, and it comprises negative electrode, anode, tank room and collection magnesium room, and negative electrode is inserted into closing down magnesium electrolysis bath tank room from electrolyzer top, and negative electrode is parallel with anode; Collection magnesium room is positioned at the side of negative electrode and anode.
Described negative electrode and positive electrode distance tank room one side wall surface 0.01 ~ 0.2m.
The upper edge of described negative electrode and positive electrode maintains an equal level, and the bottom of negative electrode and the bottom of anode maintain an equal level or lower than anode 0.01 ~ 0.2m, cathode height is 2 ~ 3m.
Described cathode thickness is 0.05 ~ 0.20m.
Described negative electrode is than anode along collection direction, magnesium room length 0.01 ~ 0.5m, and Cathode width is 1 ~ 1.5m.
Compared with prior art, positively effect of the present invention is:
The present invention changes the structure of traditional closing down magnesium electrolysis bath, employing is inserted the method for negative electrode, optimizes electric current and electrolytical mobility status in closing down magnesium electrolysis bath, take full advantage of the sense of current and electrolytical flow characteristics in electrode, improve the separation efficiency of MAGNESIUM METAL.Compared with former grooved, the MAGNESIUM METAL separation rate of upper slotting cathode type closing down magnesium electrolysis bath increases, simultaneously Structure of the cathode and the anode and arrangement more regular, electrolyzer takes up room reduction.

[embodiment]
The present invention is below provided a kind of embodiment of slotting cathode type closing down magnesium electrolysis bath.
Embodiment 1
Refer to accompanying drawing 3 and accompanying drawing 4, one being inserted the cathode type magnesium electrolytic-bath structure basic element of character is anode 1, negative electrode 2, tank room 3 and collection magnesium room 4.Negative electrode and positive electrode distance tank room one side wall surface 0.02m, the upper edge of negative electrode and positive electrode maintains an equal level, and the bottom of negative electrode and the bottom of anode maintain an equal level, cathode height is 2.2m, cathode thickness is 0.065m, and negative electrode 0.02m longer than collection direction, magnesium room, anode edge, Cathode width is 1.02m.
By electric field, thermal field, magnetic field, flow field analysis, upper slotting cathode type closing down magnesium electrolysis bath thermal equilibrium is good, and it is good that electrolyte temperature remains 700 DEG C of electrolyte flow status, and MAGNESIUM METAL separation rate has obvious lifting.
Comparative example 1
Refer to accompanying drawing 1 and accompanying drawing 2, a kind of magnesium electrolytic-bath structure basic element of character is anode 1, negative electrode 2, tank room 3 and collection magnesium room 4.Negative electrode 2 inserts electrolyzer from closing down magnesium electrolysis bath near tank room 3 side.
Contrast former magnesium electrolytic-bath structure, the collection magnesium room that upper slotting cathode type closing down magnesium electrolysis bath MAGNESIUM METAL flows into along with ionogen, and finally collect in the electrolyte levels of collection magnesium room, MAGNESIUM METAL flash liberation rate is promoted to 23% from 17%, and separation efficiency increases.Upper cathode type closing down magnesium electrolysis bath anode and cathode of inserting is arranged more regular simultaneously, has saved the space needed for producing.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, without departing from the inventive concept of the premise; can also make some improvements and modifications, these improvements and modifications also should be considered within the scope of protection of the present invention.
