Abstract
The invention discloses a method for increasing the reaction speed and reducing the energy consumption during preparation of titanium sponge from titanium tetrachloride. According to the method, the structures of a reactor and a reduction distilling furnace are correspondingly improved to ensure that the reactor becomes an improved reactor and the reduction distilling furnace becomes an improved reduction distilling furnace which is divided into an upper heating area and a lower heating area; a closed heating area is formed in a gap between a filling round groove of a asbestos cord (8) and a supporting steel hoop (7) to ensure that convection is not generated between the upper heating area and the closed heating area, the cold air conveyed from an air inlet pipe (5) in the upper heating area can not enter the closed heating area, and the heat generated in the closed heating area can not be sucked away by an air outlet pipe (6), so that the heat loss in the closed heating area is reduced, the reduction reaction speed of the titanium tetrachloride in the improved reactor is increased, and the electric energy consumption of a plurality of groups of resistance wires (4) in the lower heating area is reduced; and meanwhile, the magnesium chloride at the lower part in the improved reactor is always in a liquid state and can be smoothly discharged.
