Abstract

The invention relates to the technical field of zirconium and hafnium metallurgy, and discloses a solid-phase condensation recovery device for zirconium and hafnium metallurgy, which includes a base and a dehydration chamber. The upper part of the dehydration chamber is provided with thin tubes, and the inside of the dehydration chamber is fixedly installed with A fixed plate, the outer side of the fixed plate is provided with fine holes, the inside of the fixed plate is provided with a discharge port, the inside of the fixed plate is provided with a rotating plate, the outer side of the rotating plate is provided with a blocking column, the A second spring is fixedly connected below the blocking post. The solid-phase condensation recovery device for zirconium and hafnium metallurgy, when the rotating plate rotates, when the plugging column moves below the fine hole opened on the fixed plate, the blocking column moves up into the fine hole under the elastic force of the second spring, making the powder The water-absorbing agent will not fall, and as the rotating plate rotates, the plugging column squeezes the second spring and leaves the pores, and the water-absorbing agent falls through the pores and swayes to the lower part of the dehydration chamber, so that the powdery quicklime swayes in the dehydration chamber and is fully mixed with the dehydration chamber. The effect of water contact thereby absorbing water.

Description

technical field [0001] The invention relates to the technical field of zirconium and hafnium metallurgy, in particular to a solid phase condensation recovery device for zirconium and hafnium metallurgy. Background technique [0002] Industrial zirconium production The aluminum ash produced in the hydrogen purification process of crude zirconium tetrachloride is treated as industrial waste residue or wet-processed as raw material for the production of zirconium sulfate. It is a pity that hafnium is very rare and is discarded as waste residue or has no reasonable application. Therefore, molten salt recovery and treatment technology is widely used at present, and it is assisted to vaporize purified zirconium tetrachloride and hafnium tetrachloride at high temperature. The difference in boiling point of the alloy is used for step-by-step purification, but this purification method has the following problems. The boiling point of zirconium tetrachloride is 332 ° C, which is much h...
