Description

Technical Field

[0001] The present invention relates to the technical field of high-purity hydrochloric acid production equipment, in particular to a high-purity hydrochloric acid production condensing device. Background Art

[0002] High-purity hydrochloric acid has the molecular formula HCL, which is a colorless or slightly yellowish volatile transparent liquid with a pungent odor and a relative density (water = 1): 1.20. It is miscible with water and soluble in alkali solution. It is prohibited to mix with alkalis, amines, alkali metals, flammable or combustible materials. It is used as a raw material for the production of chlorides such as ammonium chloride, calcium chloride, zinc chloride, cuprous chloride, basic aluminum chloride, and ferric chloride. It is used in the synthesis of dyes and pharmaceutical intermediates, in the sugar and leather industries, and in metal surface treatment. During the production of hydrochloric acid, the purity of the hydrochloric acid is relatively low. However, some fields require high-purity hydrochloric acid, so it is necessary to purify the low-purity hydrochloric acid. The traditional preparation of high-purity hydrochloric acid is to heat and evaporate the low-purity hydrochloric acid to evaporate the hydrochloric acid into hydrochloric acid vapor, and then cool the hydrochloric acid vapor to obtain hydrochloric acid with higher purity. At this time, a condensing device is required.
