Description
Technical field
The utility model 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.
Utility model content
The purpose of this utility model makes upper-lower section operating temperature in reacting furnace control in required temperature, can realize cooling faster.
For achieving the above object, the utility model provides a kind of titanium sponge, sponge zirconium variable-frequency ventilation cooling system, comprise body of heater, the upper end of described body of heater is provided with forced ventilation system, described forced ventilation system comprises frequency conversion fan, blast pipe, annular collection wind band, described annular collection wind band be arranged two at least up and down in parallel, be separately positioned on the interior of body of heater, frequency conversion fan is connected to respectively by blast pipe outside each described annular collection wind band, evenly air inlet is provided with inside each described annular collection wind band, multiple air outlet is provided with above the annular collection wind band of described body of heater.A kind of titanium sponge of the present utility model, sponge zirconium variable-frequency ventilation cooling system, arrange annular collection wind band and multiple air outlet, make air intake and air-out very smooth and easy under the power of frequency conversion fan.
As further improvement of the utility model, each described air inlet is all provided with air intake arm, each described air outlet is all provided with discharge pipe, and the outside port of described discharge pipe is provided with blind plate, and described blind plate is fixed on the outboard end of described discharge pipe by holding screw.Air intake arm has the effect of reinforcing and leading, and blind plate is used for the outlet closing discharge pipe.
As further improvement of the utility model, blast pipe described in every root is also provided with valve, described valve is electric butterfly valve, and described electric butterfly valve and frequency conversion fan are controlled by central control system.Electric butterfly valve and frequency conversion fan are controlled by central control system, make the control accuracy of temperature higher.
As further improvement of the utility model, be also provided with at least one circle stopper at the lower semisection of described furnace body inside wall.
A kind of titanium sponge of the present utility model, sponge zirconium variable-frequency ventilation cooling system, forced ventilation system solves 1, the slow charging rate of radiating rate is low, and radiating rate significantly improves, and TiCl4 charging rate strengthens.The original charging rate of TiCl440 ton need be added for the whole reduction process of 10t/ stove 10t stove to need to add material in 133 hours for 300kg/h, now only need 66 hours for 600kg/h feed time.2, reactant liquor surface temperature can be controlled in ± 5 DEG C meet manufacturing technique requirent completely.
