Description
Technical field
The present invention relates to a kind of electrolyzer, be specifically related to a kind of collect magnesium chamber be arranged on electrolyzer middle part without Separating Plate Magnesium Electrolysis Cells.
Background technology
Electrolyzer is one of key equipment of electrolytic method magnesium smelting, its structure formation, every technical indicator such as cost, energy consumption that performance directly affects product.At present, commercial production of metals magnesium use electrolyzer be divided into has septalium, without three kinds of septalium, multipole grooves.Multipole groove is mainly used in the magnesium eletrolysis system that supporting titanium sponge is produced, and is characterized in that direct current consumption is lower, but high to electrolysis raw material-magnesium chloride specification of quality.There is septalium to have the shortcomings such as power consumption is high, institute's producing chlorine concentration is low, leaked chlorine is many, environmental pollution is serious, labor strength is large.Compared with having partition board electrolytic cell, without partition board electrolytic cell there is electrolyzer good airproof performance, the advantage such as to reclaim chlorine gas concentration higher, and ton magnesium direct current consumption is lower, these outstanding advantages make to be widely used in magnesium metal smelting industrial production without partition board electrolytic cell.
At present, China is existing less without partition board electrolytic cell capacity, and current efficiency is generally not high, is about 65～75%.And the collection magnesium chamber of this electrolyzer is positioned at the limit portion of electrolyzer, and negative electrode and positive electrode parallel connection is on the main bus-bar in workshop.For the electrolyzer of this structure, if will increase the group number that the electric current of electrolyzer needs to increase anode and cathode, so just need to increase the length of electrolyzer.Electrolyzer length is long, causes on the one hand the structural strength of electrolyzer to decline, and increases on the other hand area of mill site.Therefore, existing cell construction form makes electrolyzer capacity be not easy to increase, and produces thereby be not suitable for relatively large MAGNESIUM METAL factory.Therefore, develop large capacity, adaptability to raw materials good without Separating Plate Magnesium Electrolysis Cells, can fill up the blank of China's magnesium eletrolysis technology, meet the needs of large-scale electrolysis magnesium factory, for the development of China's magnesium industry from now on provides technical support.In addition, closing down magnesium electrolysis bath maximizes and can make electrolytic magnesium production energy consumption greatly reduce, and reaches the object of energy-saving and emission-reduction, meets the national industry development policies of the national energy-saving and emission-reduction of implementing, recycling economy, the strategy of sustainable development.
Summary of the invention
The object of the invention is to: provide a kind of without Separating Plate Magnesium Electrolysis Cells, existing less without Separating Plate Magnesium Electrolysis Cells capacity to solve, and be difficult for increasing electrolyzer capacity, be not suitable for the production of relatively large MAGNESIUM METAL factory, and current efficiency is not high, the problem that electrolytic magnesium production energy consumption is larger.
The solution of the present invention is as follows: a kind of large-scale baffleless magnesium reduction cell, in electrolyzer, be provided with collection magnesium chamber and tank room, top, collection magnesium chamber is provided with gas skirt, the top of tank room is provided with groove lid, collection magnesium chamber is opened in the middle part of electrolyzer, and the both sides of collection magnesium chamber are provided with tank room, between collection magnesium chamber and tank room, are provided with partition wall, on partition wall, have melt communicating passage, groove covers and also has the chlorine relief outlet being connected with tank room.
Collection magnesium chamber is along the length direction setting of electrolyzer, totally two of tank rooms, and two tank rooms are also all along the length direction setting of electrolyzer.
Described melt communicating passage is arcuate channels, and is opened in the downside of partition wall.
In tank room, be provided with negative electrode and anode.
On partition wall, also offer melt circulation pore.
The medullary ray of melt circulation pore overlaps with the medullary ray of negative electrode.
Melt circulation pore is arranged on the top of melt communicating passage.
The groove that described chlorine relief outlet is opened in tank room top covers, and the groove of each tank room top covers and only offers a chlorine relief outlet.
The present invention compared with prior art, major advantage is the middle part that collection magnesium chamber is arranged on to electrolyzer, tank room is arranged on the both sides of collection magnesium chamber, the tank room of both sides shares a collection magnesium chamber, compared with prior art, in the time that electrolyzer increases equal length, can increase by 2 multiple anode and cathode, thereby be easier to increase the strength of current of electrolyzer; On the other hand, this structure formation makes design of electrolysis cells more compact, has relatively reduced the cooling surface area of electrolyzer, therefore in increasing closing down magnesium electrolysis bath capacity, can reduce the energy consumption of electrolytic magnesium.Between collection magnesium chamber and tank room, partition wall is set, the chlorine producing after electrolysis is isolated in tank room, the magnesium globule producing after electrolysis is circulated to collection magnesium chamber with cyclic high-temperature melt by melt communicating passage, magnesium globule collects in collection magnesium chamber, realize better magnesium chlorine and separate, reduced magnesium chlorine secondary reaction, strengthened the collection of magnesium, the current efficiency 1%～5% that increases magnesium eletrolysis, makes the operation of electrolyzer more stable; The groove of each tank room top covers a chlorine relief outlet only need be set, and has compared with prior art reduced chlorine relief outlet, thereby reduces the leakage point of anode chlorine, and sealing property is strengthened.
