Liquefying and purifying device for chlorine in electrolytic magnesium chloride

Abstract

The invention relates to a liquefying and purifying device for chlorine in electrolytic magnesium chloride. The liquefying and purifying device consists of a liquefier, a pipeline A, a pipeline B, a pipeline C, a pipeline D, a pipeline E, a pipeline F, a pipeline G, a gas-liquid separator, a liquid chlorine storage tank, an intermediate tank, a tail gas treatment tank, a chlorine inlet pipe and valves, wherein the chlorine inlet pipe is arranged at the top of the liquefier; one side of the upper portion of the liquefier is connected with the gas-liquid separator through a pipeline A, and the other side of the upper portion of the liquefier is connected with the tail gas treatment tank through the pipeline G; one side of the gas-liquid separator is connected with the bottom of the liquefier through the pipeline C; the bottom of the gas-liquid separator is connected with one side of the liquid chlorine storage tank through the pipeline B, and the other side of the liquid chlorine storage tank is connected with the bottom of the tail gas treatment tank through the pipeline F; the bottom of the liquid chlorine storage tank is connected with the top of the intermediate tank through the pipeline D; the pipeline E is arranged on a side of the liquid chlorine storage tank; and the valves are respectively arranged on the pipeline A, the pipeline B, the pipeline C, the pipeline D, the pipeline E, the pipeline F and the pipeline G. According to the liquefying and purifying device disclosed by the invention, liquefying, purifying and collecting of the chlorine in the electrolytic magnesium chloride production are realized, and environmental pollution is avoided.

Description

technical field [0001] The invention relates to a production device for electrolysis of magnesium chloride, in particular to a liquefaction purification device for electrolysis of chlorine in magnesium chloride. Background technique [0002] In the whole process of sponge titanium production industry, electrolysis of magnesium chloride is an essential process. Electrolytic magnesium chloride is to electrolyze magnesium chloride to generate chlorine gas and magnesium. Magnesium is refined and then sent to the reduction distillation process to reduce with titanium tetrachloride to produce sponge titanium, while chlorine gas is sent to the chlorination process to produce crude titanium tetrachloride or as The commodity is processed for export, but the concentration of chlorine gas produced by electrolysis cannot meet the production requirements of crude titanium tetrachloride, and when it is sold as an export commodity, it must be liquefied. While performing liquefaction, it wi...
