Description
Technical field
It the utility model is related to sponge titanium smelting technical field, and in particular to a kind of pressure for magnesium method titanium sponge production
Heat abstractor.
Background technology
Titanium tetrachloride magnesiothermic reduction is a strong exothermic reaction, in reduction production period, the reactor center highest temperature
Degree is more than 1400 DEG C.Failing in time draining waste heat caused by reduction reaction, the interior external quality of titanium sponge will be influenceed,
Charging and reaction rate are reduced, extends titanium sponge production cycle and increase production cost.Reduction reaction present invention device has following
Several sinking paths, inlet and outlet, great Gai, cooling water, furnace shell and furnace bottom etc..Wherein big lid, cooling water, furnace shell and furnace bottom dissipate
Calorific value is geostationary.Domestic titanium sponge production enterprise reduction radiating mode no matter I types stove or U-shaped stove, be all using leading to
Furnace shell wind band is crossed to forcing drum air discharging and radiating form in reduction furnace, reduces reaction in furnace device temperature；Rapid heat dissipation, but it is uneven to radiate
Even, reduction reaction temperature transient fluctuation is big, and drum exhaust blower starts frequent.Magnesiothermic reduction course of reaction is a strong heat release
Journey, fuel factor is very big, removes that material heat absorption is outer, and the excess heat of release is quite a lot of in adiabatic process, in the reaction not only can be with
By self-heating maintenance reaction.But also waste heat must be excluded, it otherwise can make reactor wall overtemperature, product quality can be influenceed for a long time,
Reduction reaction speed is reduced, so waste heat must be excluded.
A kind of existing Patent No. CN200910102745.8 is entitled《A kind of radiating in sponge titanium producing process by magnesium method
Method》Chinese utility model patent disclose a kind of heat abstractor, the heat abstractor is arranged at reactor and covered greatly, is reducing
When, cooling medium is continuously passed through into heat abstractor, reaches the purpose to be radiated at the big lid of reactor.Utilize above-mentioned side
Method, in titanium sponge reduction, because reaction liquid level temperature is higher, heat is mainly directly radiated by heat radiation in the big lid of reactor
On, the temperature of the big lid of reactor is steeply risen, and cooling medium, cooling medium are constantly passed through from the cooling medium entrance of heat abstractor
Export and flow out from cooling medium, so as to realize effective heat exchange, then reached the radiating effect of reduction process in titanium sponge production
Fruit.But above-mentioned technical proposal Shortcomings, it is only radiated by covering greatly, is radiated the thermal Finite covered greatly first, its
It is secondary limited by covering progress radiating efficiency greatly, therefore effectively the heat in reduction process can not be adjusted with carrying out maneuverability
Section.
