Abstract
A reactor large cover in a process of producing a titanium sponge with a magnesium method is mainly composed of a bottom plate, a cylindrical shell and a cover plate. A heat-exchange device is arranged on the bottom plate and is provided with a medium inlet and a medium outlet which extend out of the cover plate; and a fireproof insulation material is disposed between the heat-exchange device and the bottom plate and between the heat-exchange device and the cover plate. In the reduction process, the reactor large cover continuously feeds a cooling medium into the heat-exchange device so as to radiate heat on the reactor large cover in a forced way and shorten the reduction period; and meanwhile, in the distillation process, the reactor large cover continuously feeds a flowing medium of higher than 400 DEG C into the heat-exchange device so as to guarantee the temperature of the reactor large cover, reduce the blocking ratio of the distillation channel and shorten the distillation period.
Description
Technical field
The utility model relates to the production equipment of titanium sponge, the big lid of particularly using in the titanium sponge production reduction process of reactor.
Background technology
Produce in the production of titanium sponge at existing magnesium reduction titanium tetrachloride, the type of furnace is most to adopt " U " type integrated process to produce, the big lid of reactor mainly is by base plate, cylindrical shell, cover plate is formed, between base plate and cover plate, generally be filled with flame-proof thermal insulation material, see Chinese patent " a kind of big lid of retort that is used for magnesium method production the titanium sponge " (patent No.: 200620109550.8), because reduction process is a strong exothermic reaction, reaction solution surface temperature higher (being generally about 950 ℃), heat is to big lid base plate direct radiation, cause upper cover plate by base plate thermal conduction again, adopt the big lid of this structure, be unfavorable for the heat radiation of inside reactor, easily cause the inside reactor heat radiation untimely, the product sintering occurs, 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.
Summary of the invention
The purpose of this utility model is that design provides the reactor of using in a kind of sponge titanium producing process by magnesium method big lid in order solve to produce in the titanium sponge process problem of the big lid poor radiation of reactor between reduction period.
The big lid of the reactor of using in a kind of sponge titanium producing process by magnesium method, mainly form by base plate, cylindrical shell and cover plate, on base plate, be provided with a heat exchanger, heat exchanger is provided with medium inlet and media outlet, medium inlet and media outlet extend outside the cover plate, are provided with flame-proof thermal insulation material between heat exchanger and cover plate.
In the utility model, described heat exchanger is case shape heat exchanger or tube sheet heat exchanger, and its material is high temperature alloys such as 0Cr18Ni9Ti, 1Cr18Ni9Ti, 1Cr18Si2.
Adopt the big lid of reactor of the present utility model, in reduction process, can in heat exchanger, feed heat-eliminating medium continuously, carry out the forced heat radiation purpose, shorten reduction cycle to reach from the big lid of reactor.
Employing the utlity model has following advantage and positively effect:
When 1, having overcome reduction process, it is untimely to dispel the heat in the stove, causes 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, add under the situation that equates titanium tetrachloride, reduce the reinforced time 1/3 of reduction, reduce the production cycle of titanium sponge significantly, reduce production cost, energy loss.
3, owing to the structure that sticks together at titanium sponge improves, help Mg and MgCl during distillation
2Volatilization, and reduced distillation plugging rate, thereby reduced the distillation time 1/4 of titanium sponge.
4, the utility model is simple, and is easy to operate, advantages such as long operational time.
