Description
Technical field
The invention belongs to technical field of production of sponge titanium, the reduction and distillation furnace particularly in a kind of titanium sponge production.
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, type of furnace majority adopts inverse u shape integrated process to produce, and be characterized in that single furnace output is large, qualification rate is high, the advantage that energy consumption is low.For reduce production cost, each state 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, a large amount of waste heats to be produced in reduction production process, wherein react the reaction energy of a part of heat for self of generation, other heat must constantly be got rid of, otherwise temperature raises and makes reactor wall overtemperature and make shorten 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, extend 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, namely in inverse u shape produce titanium sponge by combination method, reduction phase need dispel the heat to reduction and distillation furnace top, need be incubated whole reduction distillation when distilling, 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 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, the a large amount of residual heat of reaction in reactor top can be discharged in time when reducing, increase feed rate, shorten the production cycle, and utilize the heat energy that recoverable reduction is discharged in time, supply reduction and distillation furnace bottom and distillation use, and reduce production energy consumption.
Technical scheme of the present invention is as described below:
Reduction and distillation furnace in titanium sponge production, primarily of furnace shell, heating unit, flange, furnace bottom forms, furnace shell respectively with flange, furnace bottom connects, heating unit is provided with in furnace shell, external insulation layer, described reduction and distillation furnace is divided into the first half and Lower Half by division board, condenser is provided with in the external insulation layer of the reduction and distillation furnace first half, heat-eliminating medium inlet pipe is located at the top of division board, heat-eliminating medium goes out pipe through flange, gap and row's fistulae is provided with between base insulating layer and condenser, the upper flange in gap is provided with pressure relief opening, moderate soak layer is provided with between external insulation layer in reduction and distillation furnace bottom and base insulating layer, heat exchanger is provided with outside moderate soak layer, heat inlet pipe is arranged on the top of furnace bottom, heat goes out pipe and is arranged on below division board.
Described heat-eliminating medium is gone 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, condenser is utilized 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 recycles, namely achieve the forced heat radiation effect of reduction and distillation furnace top, bottom between reduction period and have insulation effect, reach the object increasing feed rate, reduce power consumption.
Advantage of the present invention and beneficial effect:
Instant invention overcomes the problem of the feed time length that reduction and distillation furnace top heat radiation when titanium sponge production reduces causes not in time, reduction feed rate can be improved, shorten the production cycle, simultaneously, improve reduction and distillation furnace bottom heat-retaining condition, improve the effect of full stove insulation during distillation, power consumption and production cost can be reduced.
