Apparatus for separating hydrochloric acid from germanic chloride for optical fiber

Abstract

The invention relates to a device separating hydrochloride which is mingled with germanium tetrachloride in the production of germanium tetrachloride for optical fibers, and the device belongs to a production device of the germanium tetrachloride for optical fibers. A separating device is mainly composed of a main separation column, a feed pipe, a tail gas discharge pipe, an atmosphere supply pipe, an acid discharge pipe and a discharging pipe. The top of the main separation column is connected with the feed pipe, the lateral part of which is connected with the tail gas discharge pipe, and the upper side of the main separation column is connected with the acid discharge pipe. The intermediate section of the main separation column is connected with the discharging pipe, a pipe orifice of which extends to the bottom of the main separation column, and the feed pipe is connected with the atmosphere supply pipe, the lateral part of which is communicated with the acid discharge pipe and the feed pipe respectively through two independent pipelines. When the device operates, the real-time separation process can be observed, and the hydrochloride and the germanium tetrachloride can be effectively separated. The whole separation process is isolated from air, thereby avoiding the secondary pollution of the product, and the device has the advantages of simple structure, convenience and practicality and high efficiency.

Description

technical field [0001] The invention relates to a device for separating hydrochloric acid from germanium tetrachloride in the production of germanium tetrachloride products for optical fibers, especially capable of completely separating hydrochloric acid mixed in germanium tetrachloride. It belongs to the field of special separation equipment. Background technique [0002] Germanium tetrachloride for optical fiber is an important raw material for the production of optical fiber, and has a good market demand. At present, most germanium tetrachloride for optical fiber mainly relies on foreign imports. The preparation technology of germanium tetrachloride for optical fiber has been monopolized by foreign countries. my country implements a technical blockade. [0003] Hydrochloric acid is used as a raw material in the production of germanium tetrachloride by the classical chlorination method, but germanium tetrachloride products for optical fibers have strict requirements on its...
