Abstract
A reduction device used in magnesium reduction process of titanium sponge mainly consists of a reactor and a big reactor cover. The utility model is characterized in that a radiating component is arranged on the big reactor cover, and a cooling medium inlet and a cooling medium outlet are arranged on the radiating component. The temperature of reaction liquid level in the reactor is relatively high (generally about 950 DEG C) in the magnesium reduction process of titanium sponge, and heat is directly radiated to the big cover. In the utility model, cooling media are continuously filled in the radiating component connected with the big cover, and residual heat is discharged through sufficient heat exchange. Thus, heat is timely and effectively radiated, and the purposes for solving the problem of super-high temperature in the reactor in the reduction period, timely discharging residual heat, realizing compact sponge titanium structure, reducing titanium wall deposition weight, accelerating feeding speed and reducing production period are achieved.
Description
Technical field
The utility model relates to the production unit of titanium sponge, the reducing apparatus of reduction process during particularly titanium sponge is produced.
Background technology
The industrial production titanium sponge all adopts magnesium reduction titanium tetrachloride method both at home and abroad at present, and in the reduction distillation operation, the type of furnace is most to adopt " U " type integrated process to produce, and is characterized in that single furnace output is big, high-grade-goods rate height, the advantage that energy consumption is low.For reducing production costs, each state all with equipment enlarging as technological development direction.But, along with the increase of the type of furnace, between reduction period inside reactor heat radiation untimely, easily cause centre product sintering, sandwich MgCl
2On the high side, lump amount increases, climbs the increase of ancient piece of jade, round, flat and with a hole in its centre titanium, compact product structure problem, thereby has a strong impact on the qualification rate of product, has increased the production cost of titanium sponge.Owing to be subjected to the restriction of processing condition and equipment and materials, the reduction heat-sinking capability is insufficient, and added material speed is little during the titanium sponge reduction, and the reinforced time is long, has had a strong impact on the whole production cycle.For this reason, abroad some producers have adopted the heat radiation of furnace shell forced ventilation, but still can not deal with problems at all.
The utility model content
The purpose of this utility model is to solve producing in the titanium sponge process between reduction period the reactor interior reaction temperature too high, causes problems such as the reduction feed rate can not improve, and has designed the reducing apparatus in a kind of sponge titanium producing process by magnesium method.
Reducing apparatus in a kind of sponge titanium producing process by magnesium method mainly is made up of reactor and the big lid of reactor, it is characterized in that covering greatly at reactor being provided with thermal component, and thermal component is provided with the heat-eliminating medium inlet and heat-eliminating medium exports.
Owing to produce in the reduction process of titanium sponge in the magnesium method, reaction solution surface temperature higher (being generally about 950 ℃) in the reactor, heat is to big lid direct radiation, after adopting the utility model, by continuously to thermal component that big lid links to each other in feed heat-eliminating medium, discharge waste heat by sufficient heat exchange, thereby realize heat radiation timely and effectively, reach the too high timely eliminating waste heat of inside reactor temperature between the solution reduction period, solve the titanium sponge compact structure, reduce and climb ancient piece of jade, round, flat and with a hole in its centre titanium weight, the purpose of increase feed rate minimizing production cycle.
At thermal component described in the utility model, be connected reactor by section bars such as plate, grooves and cover greatly, cover greatly at reactor and form airtight or open topped cavity, be respectively equipped with heat-eliminating medium inlet (4) and heat-eliminating medium outlet (5) at the two ends of cavity
In the utility model, described heat-eliminating medium is argon gas or pressurized air, and is further outstanding radiating effect, goes back water, refrigerated water, liquid metal or liquid alloy etc., to increase radiating effect.
Heat dissipating method of the present invention has following advantage and positively effect:
1, it is untimely to have overcome in the stove centre heat radiation, causes centre titanium sponge sintering, sandwich MgCl
2The compact structure problem on the high side with lump.
2, because of having realized radiating effect, can improve the reduction feed rate greatly,, reduce recovery time 30h, reduce the production cycle of titanium sponge significantly, reduce production cost, energy loss adding under the situation that equates material.
3, because of having realized radiating effect,, significantly reduced the weight of climbing ancient piece of jade, round, flat and with a hole in its centre titanium, increased the percentage of product and the qualification rate of product in the reduction middle and later periods.
4, owing to the structure that sticks together at titanium sponge improves, help Mg and MgCl during distillation
2Volatilization, thereby reduce the distillation time of titanium sponge.
5, present method also has advantages such as simple, easy to operate, long operational time.

Embodiment
With embodiment the present invention is described in further detail in conjunction with the accompanying drawings.
Embodiment 1:
As shown in Figure 1, reducing apparatus in a kind of sponge titanium producing process by magnesium method, mainly be made up of reactor 1 and the big lid 2 of reactor, it is characterized in that covering greatly at reactor and be provided with thermal component 3, thermal component 3 is provided with heat-eliminating medium inlet 4 and heat-eliminating medium outlet 5.
Utilize the utility model, when titanium sponge reduction, because reaction solution surface temperature higher (being generally about 950 ℃), heat mainly by the thermal radiation direct radiation on the big lid 2 of reactor, the temperature of the big lid 2 of reactor sharply rises, and from the heat-eliminating medium inlet 4 continuous heat-eliminating mediums that feed of thermal component 3, heat-eliminating medium flows out from heat-eliminating medium outlet 5, thereby realize effective heat exchange, then reached the radiating effect of reduction process during titanium sponge is produced.
Shown in Figure 2 is that thermal component 2 is connected reactor by sheet material and covers greatly in the utility model, covers greatly at reactor and forms airtight or open topped cavity, is respectively equipped with heat-eliminating medium inlet 4 and heat-eliminating medium outlet 5 at the two ends of cavity.
In actual application, heat abstractor 2 can also be directly connected in reactor by section bars such as channel-section steels and cover greatly, covers greatly at reactor and forms airtight or open topped cavity, establishes heat-eliminating medium inlet 4 and heat-eliminating medium outlet 5 respectively at the two ends of cavity.
