Furnace.
Background technique
Industrial production titanium sponge is all made of magnesium-reduced titanium tetrachloride method both at home and abroad at present, which is that heat release is anti-
It answers, when production issues a large amount of waste heat, reactor need to be discharged in waste heat in time.In reduction distillation process, type of furnace majority is used
Inverse u shape combination method produces titanium sponge, and the enlargement of the feature type of furnace, single furnace output are high, the advantage that low energy consumption.But with also
The increase of the original distillation type of furnace, i.e. titanium sponge production equipment reactor and reduction and distillation furnace diameter and height increases, during reduction
Reactor center position is radiated not in time, and centre temperature drift (up to 1200 degree or more) causes centre titanium sponge
Sintering, sandwich MgCl2Distillation is difficult, lump amount increases, climbs wall titanium amount increases, compact product structure problem, to seriously affect
The qualification rate of product, percentage of product influence the product filling rate of titanium sponge.Due to being limited by process conditions and equipment and materials, also
Former heat-sinking capability is limited, and reduction reaction face is little during titanium sponge reduction, leads to material speed less, feed time is long, seriously affects
Entire production cycle.The heating surface area of former heating furnace is limited during distillation, leads to the disadvantages of distillation time is long, power consumption is high.
Titanium sponge production reduction distillation type of furnace structure is well formula circle electric furnace at present, and surrounding and internal furnace are circle
Structure, the use of the structure secure the structure of reactor, with the heat-sinking capability at the enlarged reactor center position of the type of furnace
It is restricted, because the size of reactor is big when distillation, heating furnace is heated to the titanium centre that sticks together and needs a large amount of time, distills energy
Power is restricted.It needs to restore aspect and radiating surface when titanium sponge reduction produces, when distillation needs the heating surface of reduction and distillation furnace
After titanium sponge reduction production, distillation production is carried out, the distillation of Sponge Titanium needs to carry out reactor for a long time
Heating, heating surface (area) (HS is bigger, and distillation speed is faster, save power consumption it is bigger, it is desirable that reduction and distillation furnace have biggish distillation surface area,
Good heat insulation effect and sealing performance.
Though existing circle pit furnace is a kind of heating equipment of maturation, the heat-sinking capability of heating furnace, heating energy
Power, thermal insulation property be not it is highly desirable, when carrying out large-scale joint furnace design, by reasonably calculating and designing, make to restore rank
The heat-sinking capability of section is much higher than original type of furnace, and the heating efficiency for distilling the stage is much higher than original type of furnace.By to guarantor
The redesign of warm layer and heat insulation layer, performance of the heating furnace in the distillation stage are also significantly better than original type of furnace, not only meet
Large-scale reduction distillation combination method produces requirement of the titanium sponge technique to heating furnace, to the single furnace output of raising, increases charging rate, contracting
Short distillation production cycle, the qualification rate of raising titanium sponge and percentage of product have positive effect.
Utility model content
In order to solve the problems existing in the prior art, the utility model design provides a kind of reduction of magnesium processes production titanium sponge
The heat-sinking capability of reduction process and the heating efficiency of distillation process can be substantially improved in retort, so as to shorten the production cycle, reduce
Energy consumption, and can Improving The Quality of Products.
The technical solution of the utility model is:
A kind of reduction and distillation furnace of magnesium processes production titanium sponge, is mainly welded on bottom plate by shell, inner casing and constitutes groined type
Furnace chamber is equipped with insulating layer in furnace wall, cover board is equipped at the top of furnace wall, insulating layer is equipped with heating element, between shell and inner casing
Equipped with gap, it is equipped with securing plate therebetween, the cross section of groined type furnace chamber is rectangle or kidney ellipsoid or ellipse.
Further, the middle part of the reduction and distillation furnace is equipped with 4 or more reduction cold wind inlet pipes, in reduction and distillation furnace
Top sets 6 or more reduction hot gas outlet pipes, and reduction cold wind inlet pipe, reduction hot gas outlet pipe are stretched in burner hearth, steamed in reduction
Distillation hot gas inlet pipe and distillation hot gas outlet pipe are respectively equipped on the shell on furnace bottom and top.
Further, the heating element material is Aludirome, and insulating layer is that compressed fibre brick masonry forms.
In the utility model, the rectangle or kidney ellipsoid or ellipse of the cross section of furnace chamber can increase compared with the existing type of furnace
Add the reaction surface and heat dissipation area of reduction process, and in distillation, then heating evaporation surface area is increased, in reduction phase to anti-
The heat-sinking capability for answering device, the express delivery ability that feeds and distillation ability, the thermal insulation property for distilling stepwise heating furnace are reinforced, and mention
High charging rate and the high constant temperature time of shortening shorten the reduction distillation production cycle, can reduce titanium sponge production power consumption.
In the present invention, reduction and distillation furnace can be passed through cold air using reduction cold wind inlet pipe in reduction phase, and lead to
Reduction hot gas outlet pipe is crossed to shed part reduction reaction heat；In the distillation stage, another reduction is imported using distillation hot gas inlet pipe
The heat of system keeps the temperature furnace shell, thereby saving energy consumption.
Heating element in the utility model replaces existing nichrome material with Aludirome, ensure that and is forcing
Under ventilation and high temperature, heating element is not vulnerable to atmospheric corrosion.
In the present invention, exhausted instead of original toxic asbestos board with the fiber brick building heat insulation layer of compression moulding
Thermosphere, expanded vermiculite, clay brick etc., improved insulating layer thermal insulation property is good, and long service life.
The lower advantage and good effect of the utility model:
1, the heating distance and forced ventilation heat-sinking capability to stick together to reactor center titanium is shortened, is overcome in reactor furnace
Center portion position is radiated not in time, and the sintering of centre titanium sponge, sandwich MgCl are caused2Distillation is not thorough to be caused with lump structure on the high side
Close problem.
2, because of the reduction reaction area and cooling surface area of increase reactor when reduction feeds, reduction charging speed is greatly improved
Degree reduces reduction feed time 35h, drastically reduces the production cycle of titanium sponge, reduces production cost, power consumption loss.
3, surface area is distilled because increasing in distillation, reduces heating furnace and sticks together centre distance to titanium, shorten distillation production week
Phase 40 hours, distillation power consumption is reduced, effect is obvious.
4, using novel furnace structure, utilize reduction waste heat rationally.
5, it uses fiber brick as heat insulation layer and insulating layer, instead of original toxic asbestos board heat insulation layer, expanded vermiculite, glues
Cob brick increases the thermal insulation property of stove, extends the service life of heating furnace.
The advantages that present apparatus equipment is simple, easy to operate, long operational time, heat dissipation, good heat insulation effect is a kind of very real
With effective utility model device.
