Description
Technical field
The present invention relates to titanium sponge, sponge zirconium production technical field, particularly a kind of titanium sponge, sponge zirconium variable-frequency ventilation cooling system.
Background technology
At present, sponge titanium smelting all adopts Kroll process to produce product.Mainly adopt fused salt chlorimation, I type also steam stove technology, fluidizing chlorination and the type of falling U also steam stove technology production titanium sponge abroad, domestic, mainly adopt upper magnesium chloride formula I type of arranging to go back steam stove technology with U is small-sized.Along with China's titanium sponge production technology development, production technology constantly perfect, also increasingly maximize for improving the cost-saving 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 shortening single stove production cycle reduces costs and improves titanium sponge grade, has become each titanium sponge factory urgent problem.
The magnesiothermic reduction of TiCL4 is a strong exothermic reaction.Pass through actual measurement, at reduction production period, reactor central temperature is the highest exceeds 1400 DEG C, if fail in time the waste heat that reduction reaction produces to be drained, the interior external quality of titanium sponge will be affected, reduce reinforced and reaction rate, prolongation titanium sponge production cycle and increase production cost.At reduction production period, usual reactor is mainly through heat radiations such as inlet and outlet, great Gai, cooling water, furnace shell and furnace bottoms.Wherein 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 opening airduct needs workman to climb up furnace shell outer platform, and turning on flange holding screw unloads blind plate by hand.
The shortcoming of this radiating mode mode is as follows:
1, the slow charging rate of radiating rate is low: the reduction process of TiCl4 is carried out in the solid, liquid, gas state multiphase coexistence system containing Ti, TiCl2, TiCl3, TiCl4, Mg, MgCl2, also be an exothermic reaction simultaneously, in order to maintain normal temperature, prevent the generation of ferro-titanium, good heat radiation must be carried out, and this mode just limits reduction reaction rate, charging rate (the fast 280-320kg/h of the average material) reduction cycle reducing Ticl4 is 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 it is high that temperature reaches ferrotianium lowest total of the melting point generation ferro-titanium titanium sponge iron-holder more than 1085 ° of C, and product grade declines and causes economic loss.
3, labour intensity is large exists potential safety hazard: in production process, workman will climb up the manual blind plate opening or closing all in/out air tubes of furnace wall outer platform of 3-4 rice, whole operating process needs 1-1.5 hour, work under bad environment, the narrow and small environment temperature of workbench operations area can reach 60 DEG C, easily the accident such as heatstroke and burn occurs.
Summary of the invention
