Description
Technical Field
The invention relates to a device for producing titanium sponge, in particular to a large cover with a heat-preservation heating and connecting device for titanium sponge distillation production.
Background
At present, the industrial production of titanium sponge at home and abroad adopts a method for reducing titanium tetrachloride by magnesium. The method comprises the steps of adding liquid magnesium into a reactor, continuously adding titanium tetrachloride to react with the liquid magnesium to obtain granular titanium, slowly forming titanium sponge lump, after reduction charging production is finished, carrying out distillation production to remove a small amount of magnesium and magnesium chloride in the titanium lump, and adopting a distillation furnace type mode to comprise a series furnace and a parallel furnace (an inverted U-shaped combination method). In the reduction distillation production process, most furnace types are produced by adopting an inverted U-shaped combined method, and the method has the advantages of large yield, high qualification rate, low energy consumption, low labor cost and the like compared with a small single furnace. In order to improve the production quality of the titanium sponge and reduce the production cost, the large-scale equipment is taken as a technical development direction in all countries. The combined furnace parallel connection furnace is characterized in that a cold end reaction tank which is the same as a hot end system is connected with a passage (the passage is connected by a transverse pipe and a vertical pipe in a welding way) arranged on a large cover in the prior art by a transverse pipe beside a reduction production furnace, and the joint of the hot end transverse pipe and the cold end transverse pipe is connected with the cold end reaction tank in a welding way. Magnesium and magnesium chloride steam is distilled from a hot end system to a cold end system through a passageway, and in order to ensure that the high-temperature magnesium and the magnesium chloride steam are not condensed in the passageway, a vertical pipe heater and a transverse pipe heater are independently installed on a passageway vertical pipe above a large cover panel. The vertical pipe heater and the horizontal pipe heater are large in size, the overhead travelling crane is required to hoist each time the vertical pipe heater and the horizontal pipe heater are mounted and dismounted, and the operation of workers for butting the passage takes about 2 hours during assembling and dismounting; when heating, the heater is heated to above 850 ℃ to consume electric energy; during distillation, the welding of the vertical pipe and the transverse pipe is easy to generate cracks, and if leakage occurs, production has to be stopped and the product quality is affected; under the high-temperature and high-vacuum environment, the pressure difference between the inside of the passageway and the outside is large, so that the passageway pipe is easy to deform, and the welding line is easily cracked by thermal stress, so that the production is stopped and the product quality is influenced; when the junction of the hot end transverse pipe and the cold end transverse pipe is connected by welding, in order to prevent the hot end titanium sponge lump from being polluted by air inflow, argon gas must be continuously filled into the hot end reactor for protection, the argon gas flows out from the pressure relief port for 3 hours, the welding time is long, the argon gas is wasted, and the possibility of polluting products by air inflow is also caused.
