Abstract
The invention relates to a reduction distillation device for producing sponge titanium, mainly comprising a reaction tank (1), a big cover (6) and a sieve plate (2), wherein the sieve plate (2) is arranged in the reaction tank (1), a sealing ring (5) is arranged between the big cover (6) and the reaction tank (1), and a component (3) used for increasing the evaporation surface area of a titanium lump is arranged on the sieve plate. After the invention is adopted to carry out the reduction distillation production of the sponge titanium, the evaporation surface area of the titanium lump can be increased, and the molecular diffusion resistance can be reduced. Because only the component used for increasing the evaporation surface area of the titanium lump is arranged on the sieve plate of the prior art, the invention has simple structure and low execution cost, can effectively solve the problem that sandwich titanium with high content of magnesium chloride in the titanium lump is difficult to distill completely, and greatly reduces the distillation time.
Description
Technical field
The present invention relates to the titanium smelting technology, particularly magnesium reduction is produced the method and apparatus of titanium sponge.
Background technology
The industrial production titanium sponge all adopts magnesium metal reduction titanium tetrachloride method both at home and abroad at present, promptly in the reduction distillation operation, in the reaction unit bottom sieve plate is set earlier, utilize the magnesium metal reduction titanium tetrachloride to obtain titanium sponge and magnesium chloride, magnesium chloride discharges on time, and titanium sponge is deposited on the sieve plate and forms titanium and stick together, after reduction finishes, Impurity removals such as magnesium chloride in employing distillation mode sticks together titanium, thus purified titanium sponge obtained.At present, for reducing production costs, each state all with equipment enlarging as technological development direction, still, to be difficult to distillation clean for the muriate in centre along with the increase of the type of furnace, particularly titanium stick together, sandwich MgCl
2On the high side, lump amount increases, the compact product structure problem, have a strong impact on the qualification rate of product, in when distillation, the stick together muriate in centre of titanium can take a large amount of time, waste power consumption and increased the production cycle, increased the production cost of titanium sponge and operative employee's labour intensity.For this reason, 200810068707.0) and " a kind of heating unit of producing in the titanium sponge distillation reactor " (application number: technology such as 200810067708.5) Zunyi Titanium Industry Co. Ltd. has developed " heat radiation of titanium sponge production reduction process and titanium stick together hole-forming device " (application number: in 2008, though this two technology has solved the problems referred to above to a certain extent, but because technical sophistication, cost is higher during practical application.
Summary of the invention:
At the problems referred to above, the present invention has developed a kind of reduction distillation device of producing titanium sponge on the prior art basis, can effectively solve in the titanium sponge production distillation time long, improve distillation efficiency, problem such as reduce production costs, but also be convenient to operation.
Technical scheme of the present invention is: a kind of reduction distillation device of producing titanium sponge, mainly comprise retort, lid and sieve plate are formed greatly, sieve plate places in the retort, is provided with sealing-ring between lid and the retort greatly, and sieve plate is provided with and increases the stick together parts of evaporation surface of titanium.
After adopting the present invention to carry out titanium sponge reduction distillation production, the titanium sponge that titanium tetrachloride and molten metal reactive magnesium generate can be piled up along increasing the stick together parts of evaporation surface of titanium, after reduction finishes, enter in the still-process, can increase evaporation surface and minimizing molecular diffusion resistance that titanium sticks together.
In the present invention, increase titanium stick together the parts of evaporation surface can be arranged on sieve plate in the heart or on other position of sieve plate.
In the present invention, increasing the stick together parts of evaporation surface of titanium can be any section bars such as plate, rod, pipe, cylindrical shell more than 1, also can be the subassembly of the arbitrary profiles such as plate, rod, pipe, cylindrical shell more than 1.
In the present invention, increase titanium and stick together the parts of evaporation surface when being tabular, its along retort the size on radial and axial all 〉=the titanium size that sticks together.
In the present invention, increasing the stick together parts of evaporation surface of titanium can be titanium or titanium alloy or carbon steel or steel alloy etc.
In the present invention, increase titanium and stick together the parts material of evaporation surface when being carbon steel, go into during titanium sponge sticks together, influence quality product, can be provided with in this member outer surface and ooze titanium layer for preventing to increase the stick together chemical element of parts of evaporation surface of titanium itself.
Advantage of the present invention and positively effect are: the present invention only is provided with on the sieve plate of prior art and increases the stick together parts of evaporation surface of titanium, and it is simple in structure, and implementation cost is low, but has produced unforeseeable remarkable technique effect:
1, the present invention has overcome titanium sponge and has sticked together when distillation, contain the high sandwich titanium of magnesium chloride during titanium sticks together and be difficult to distill clean problem, and Lu Xing more is big, and effect is obvious more, is example with 12 tons/stove, compared with prior art, reduce and to contain the high sandwich titanium 150～250kg/ stove of magnesium chloride, basically eliminate the sandwich product of magnesium chloride, its technique effect and employing " a kind of interior heating unit of titanium sponge distillation reactor of producing " technology is suitable.
2, behind employing the present invention, when distillation, owing to increased evaporation surface and the diffusional resistance that has reduced volatile matter, reduced distillation time significantly, with the 12 tons/type of furnace is example, and compared with prior art, every stove reduces by 2/5～1/2 distillation time, compare with adopting " a kind of heating unit of producing in the titanium sponge distillation reactor " technology, every stove reduces by 1/5～2/5 distillation time.Therefore, the present invention greatly reduces production cost, energy loss, labour intensity.
