Description
Technical field
The present invention relates to titanium sponge, sponge zirconium production technical field, particularly to a kind of titanium sponge, the energy-conservation reacting furnace of sponge zirconium.
Background technology
At present, sponge titanium smelting all uses Kroll process to produce product.External fused salt chlorimation, I type also steam stove technology, fluidizing chlorination and inverted U also steam stove technology is mainly used to produce titanium sponge, domestic, main use upper row's magnesium chloride Formulas I type and U is small-sized goes back steam stove technology.Along with the development of China's titanium sponge production technology, production technology the most perfect, the most increasingly maximize for improving the cost-effective smelting furnace of production capacity, single furnace output improves constantly.Along with the lasting doldrums of international economy form since 2009, drop in price one tunnel of titanium sponge.How to shorten single stove production cycle and reduce cost raising titanium sponge grade, it has also become each titanium sponge factory urgent problem.
TiCL4Magnesiothermic reduction be a strong exothermic reaction.Measured by reality, at reduction production period, reactor central temperature is the highest exceeds 1400 DEG C, failing to drained by the waste heat that reduction reaction produces in time, will affect the interior external quality of titanium sponge, reduces charging and reaction rate, prolongation titanium sponge production cycle and increase production cost.At reduction production period, usual reactor is mainly by heat radiations such as inlet and outlet, great Gai, cooling water, furnace shell and furnace bottoms.The most most importantly by inlet and outlet reactor reactant liquor worn and dispel the heat.Radiating mode is got involved without external force, and reactor heat is got rid of in gravity-flow ventilation.The mode of unlatching airduct needs workman to climb up the manual flange fastening screw of turning on of furnace shell outer platform and unloads blind plate.
The shortcoming of this radiating mode is as follows:
1, the slow charging rate of radiating rate is low: TiCl4Reduction process be containing Ti, TiCl2 、TiCl3、TiCl4 、Mg、 Mg Cl2Solid, liquid, gas state multiphase coexistence system in carry out, be also an exothermic reaction simultaneously, in order to maintain normal temperature, prevent the generation of ferro-titanium, it is necessary to carry out good heat radiation, and this mode limits reduction reaction rate, reduce TiCl4Charging rate (average material speed 280-320kg/h) reduction cycle long, production cost remains high, and also constrains the maximization of equipment simultaneously.
2, reactant liquor wears the bad control of temperature: easily cause overtemperature or local overheating in production process, and temperature reaches ferrotianium lowest total of the melting point more than 1085 ° of C and generates ferro-titanium titanium sponge iron-holder height, and the decline of product grade causes economic loss.
3, the big potential safety hazard that exists of labor intensity: in production process, the furnace wall outer platform of workman 3-4 to be climbed up rice manually opens or close the blind plate of all in/out air tubes, whole operating process needs 1-1.5 hour, work under bad environment, up to 60 DEG C, easily there is the accident such as heatstroke and burn in the narrow and small ambient temperature of work platforms operations area.
