Automatic magnesium chloride discharging and waste gas collecting device for titanium sponge production and production process thereof

Abstract

The invention discloses an automatic magnesium chloride discharging and waste gas collecting device for titanium sponge production and a production process thereof. According to the device, an electromagnetic valve and a water ring vacuum pump are arranged on a waste gas conveying pipe; a waste gas collecting device is arranged on one end of the waste gas conveying pipe; the outlet end of a magnesium chloride pipe on a reactor is connected with a magnesium chloride conveying pipe through a magnesium chloride conveying branch pipe; a high-temperature valve is arranged on the magnesium chlorideconveying branch pipe; and a baffle is arranged at the bottom of the magnesium chloride conveying pipe. The discharge time of magnesium chloride is determined according to the amount of titanium tetrachloride, when the magnesium chloride needs to be discharged by calculating, the water ring vacuum pump is started five minutes earlier, the high-temperature valve and a pressure charging valve are opened, argon is charged into the reactor for ten minutes, liquid magnesium chloride and flue gas flow into the magnesium chloride conveying pipe under the action of high pressure, the magnesium chloride flows into an electrolytic tank, and the flue gas is pumped into the waste gas collecting device. The magnesium chloride can be automatically discharged during reduction, centralized transportationand waste gas collection are achieved, power consumption is saved, cost is reduced, and labor environment is improved.

Description

technical field [0001] The invention relates to an automatic discharge and waste gas collection device and a biological device for the production of magnesium chloride from sponge titanium. [0002] production process. Background technique [0003] At present, the industrial production of sponge titanium at home and abroad adopts the method of reducing titanium tetrachloride with magnesium, that is, continuously feeding liquid titanium tetrachloride into the closed reactor to react with liquid magnesium to form sponge titanium and magnesium chloride. In order to achieve the continuity and stability of sponge titanium production Yield, in the production process, after feeding for a period of time, the magnesium chloride in the reactor increases and the liquid level rises. The magnesium chloride should be discharged in time. The discharge of magnesium chloride can not only take away the excess reaction heat, but also maintain the continuity of production. However, the current...
