Description
[technical field]
The present invention relates to cell technologies field, specifically, be a kind of high current efficiency double collection magnesium room
Closing down magnesium electrolysis bath.
[background technology]
Magnesium is the lightest non-ferrous metal, it is possible to the good and alloy of other metal composition high intensity, and not
The disconnected castability improved makes its application increasingly wider, is the useful supplement of conventional aluminum alloy etc..In U.S.
State, there is explosive growth in fields such as consumer electronics, automobile, medical treatment in magnesium alloy, has greatly replacement aluminum to close
The gesture of the conventional alloys such as gold.Magnesium serves not only as lightweighting materials and enjoys expectation, also as magnesium fuel cell
Electrode constituting material, have important application at battery industry.
China is magnesium resource big country, Ye Shi magnesium metal big producing country, but production method with Pidgeon process is mainly
Main.State's internal electrolysis production process equipment is backward, grooved is little, current efficiency and production efficiency is low, energy consumption
High.External electrolysis installation current intensity is big by contrast, and automaticity is high, and unit are magnesium metal produces
Amount height, power consumption is low.The current efficiency of the non-inductive windings closing down magnesium electrolysis bath that China runs at present is low, only 76~78
About %, magnesium metal separation efficiency is low, and whole magnesium eletrolysis is industrial and external gap is huge.
Based on the research to advanced magnesium eletrolysis technique, design and possess low-energy-consumption, the separation of high magnesium metal
The electrolysis bath of rate.Exploitation simultaneously has a magnesium eletrolysis key technology of China's independent intellectual property right, further with
Gas chemical industry organically combines, and forms every resource such as magnesium, gas chemical industry and mutually relies on, supports mutually
Industry chain of circular economy, reach the maximization of the utilization of resources and the optimization of economic benefit.
[summary of the invention]
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of high current efficiency double collection magnesium room
Closing down magnesium electrolysis bath.
It is an object of the invention to be achieved through the following technical solutions:
A kind of closing down magnesium electrolysis bath of high current efficiency double collection magnesium room, closing down magnesium electrolysis bath comprises minus plate, positive plate and
Collection magnesium room, the number of collection magnesium room is two, is separately positioned on the both sides of minus plate and positive plate, and two
Collection magnesium room is symmetric.
Described minus plate and positive plate spacing are 0.03~0.08m.
Described minus plate is inserted into closing down magnesium electrolysis bath from electrolysis bath top or bottom.

Compared with prior art, the positive effect of the present invention is:
The present invention changes the structure of tradition closing down magnesium electrolysis bath, uses two symmetrical collection magnesium rooms, two collection magnesium
Take between room to insert or the method for lower slotting cathode and anode.This structural change electrolysis mass flow of closing down magnesium electrolysis bath
Emotionally condition, takes full advantage of the flow behavior of electrolyte, improves the separation efficiency of magnesium metal.With former groove
Type is compared, and the magnesium metal separation efficiency of the most double collection magnesium rooms electrolysis bath is greatly improved, and effect is obvious.
