Filtering apparatus of reduction jar and filtering method

Abstract

The invention relates to a field for producing titanium sponge through reducing titanium tetrachloride by magnesium, and especially relates to a filtering apparatus of a reduction jar and a filtering method, and the invention has the purpose that harmful substances in the reduction jar is absorbed and filtered, and then the clean air is discharged. A structure of the filtering apparatus of the reduction jar is characterized in that a left cylindrical shell and a right cylindrical shell are arranged at two sides of the upper part of a chute, an inlet is arranged at the upper lateral part of the left cylindrical shell, an outlet is arranged at the upper lateral part of the right cylindrical shell, a hopper and a filter are arranged in the right cylindrical shell, a cleaning aperture is arranged at the left side of the chute, the left cylindrical shell and the right cylindrical shell are respectively communicated to the chute, so that a U-shaped filter is composed. The filtering apparatus has the advantages that the harmful substances in the reduction jar is absorbed and filtered, and then the clean air is discharged, the environmental pollution is reduced, titanium sponge with high purity can be produced by the reused reduction jar, and the usage life of the reduction jar is simultaneously increased.

Description

Technical field [0001] The invention relates to the field of magnesium-reduced titanium tetrachloride to produce sponge titanium, in particular to a reduction tank filtering device and a filtering method for producing sponge titanium. Background technique [0002] The process of reducing titanium tetrachloride by magnesium to produce titanium sponge is carried out in a reduction tank. When the reduction tank is used again, there are a lot of harmful substances such as water vapor, dust, and hydrochloric acid vapor in the tank. Seriously affect the quality of sponge titanium. At present, the method used is to use a vacuum device to extract these substances and directly discharge them to cause pollution. Summary of the invention [0003] The present invention provides a reduction tank filter device and a filtering method for producing sponge titanium in order to solve the above problems. Its purpose is to absorb and filter harmful substances in the reduction tank to discharge clean...

AI Technical Summary

Problems solved by technology

[0002] The process of magnesium reduction of titanium tetrachloride to produce sponge titanium is carried out in the reduction tank. When the reduction tank is used again, there are a lot of harmful substances such as water vapor, dust and hydrochloric acid gas in the tank. The existence of these substances will cause Seriously affect the quality of titanium sponge

At present, the method adopted is to use a vacuum device to extract these substances and discharge them directly to cause pollution.
