Description
Technical field
The invention belongs to titanium sponge production technical field, the reduction and distillation furnace that particularly a kind of titanium sponge is used in producing.
Background technology
Industrial production titanium sponge all adopts magnesium reduction titanium tetrachloride method both at home and abroad at present, and in reduction distillation operation, the most inverse u shape integrated processs that adopt of the type of furnace are produced, and are characterized in that single furnace output is large, and qualification rate is high, the advantage that energy consumption is low.For reducing production costs, each state is all using equipment enlarging as technological development direction.The reaction of magnesium reduction titanium tetrachloride is a thermopositive reaction, on reduction and distillation furnace top and reactor top, in reduction production process, to produce a large amount of waste heats, a part of heat that wherein reaction produces is for the reaction energy of self, other heat must constantly be got rid of, otherwise temperature rising makes reactor wall overtemperature and is shortened the work-ing life of reactor apparatus, also increase iron in reactor to velocity of diffusion in liquid magnesium, product iron content is increased, and feed time is increased, extended the titanium sponge production cycle.In reduction and distillation furnace, bottom and reactor lower part, need external heat to maintain melt temperature to ensure temperature and the magnesium chloride exhaust temperature of liquid magnesium, in inverse u shape produce titanium sponge by combination method, reduction phase need dispel the heat to reduction and distillation furnace top, in the time of distillation, need be incubated whole reduction distillation, in existing reduction and distillation furnace, between reduction period, top heat generally adopts external ventilation to distribute, unrealized recycling.
Summary of the invention
Have problems for solving in prior art, the invention provides the reduction and distillation furnace of using in a kind of titanium sponge production, adjustable upper and lower two temperature at different times of reduction and distillation furnace in process of production, in the time of reduction, can discharge in time a large amount of residual heat of reaction in reactor top, increase feed rate, shorten the production cycle, and the heat energy that utilizes recoverable reduction to discharge in time, supply with reduction and distillation furnace bottom and distillation use, reduce production energy consumption.
Technical scheme of the present invention is as described below:
The reduction and distillation furnace that titanium sponge is used in producing, mainly by furnace shell, heating unit, flange, furnace bottom composition, furnace shell respectively with flange, furnace bottom connects, in furnace shell, be provided with heating unit, external insulation layer, described reduction and distillation furnace is divided into the first half and Lower Half by division board, in the external insulation layer of the reduction and distillation furnace first half, be provided with condenser, heat-eliminating medium inlet pipe is located at the top of division board, heat-eliminating medium goes out pipe through flange, between base insulating layer and condenser, be provided with gap and row's fistulae, in the upper flange in gap, be provided with pressure relief opening, thermal insulation layer in the middle of being provided with between external insulation layer in reduction and distillation furnace bottom and base insulating layer, middle thermal insulation layer is provided with heat exchanger outward, heat inlet pipe is arranged on the top of furnace bottom, heat goes out pipe and is arranged on division board below.
Described heat-eliminating medium goes out pipe and is connected with heat inlet pipe by pipeline.
Described condenser is tubular(surface)condenser.
Described heat exchanger is tubular heater exchhanger.
In the present invention, utilize condenser to carry out forced heat radiation to reduction and distillation furnace top between reduction period, and heat is transported to reduction and distillation furnace by heat exchanger and recycles, having realized the forced heat radiation effect of reduction and distillation furnace top, bottom between reduction period has insulation effect, reaches the object that increases feed rate, reduces power consumption.
Advantage of the present invention and beneficial effect:
The reduction and distillation furnace top problem that the feed time that causes is not in time grown of dispel the heat when the present invention has overcome titanium sponge and produces reduction, can improve reduction feed rate, shorten the production cycle, simultaneously, improve reduction and distillation furnace bottom heat-retaining condition, while having improved distillation, the effect of full stove insulation, can reduce power consumption and production cost.
