Anti-blocking emergency operation type alkali liquid spraying tower for purifying germanium tetrachloride

Abstract

The invention relates to the technical field of chemical production and discloses an anti-blocking emergency operation type alkali liquid spraying tower for purifying germanium tetrachloride. The anti-blocking emergency operation type alkali liquid spraying tower comprises a first-grade spraying tower, wherein the bottom of the first-grade spraying tower is fixedly connected with the ground; the top of the first-grade spraying tower is fixedly connected with an adapting pipe; one end, far away from the first-grade spraying tower, of the adapting pipe is fixedly connected with a second-grade spraying tower; an exhausting pipe is fixedly connected with the top of the second-grade spraying tower; the left side face of the first-grade spraying tower and the left side face of the second-grade spraying tower are fixedly connected with maintenance windows. According to the anti-blocking emergency operation type alkali liquid spraying tower for purifying the germanium tetrachloride, a slidinggroove is arranged so that a liquid receiving plate can slide downward in the sliding groove under the action of gravity; finally, a filler layer at the bottom of the first-grade spraying tower can rapidly fall down to the top of the liquid receiving plate through setting an inserting hole, a safety rod and a pull ring, so that the aim of providing a spraying tower blocking emergency measure is realized.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to an anti-clogging type lye spray tower which can be operated in an emergency and is used for purifying germanium tetrachloride. Background technique [0002] High-purity germanium tetrachloride is one of the important dopants in the production of optical fibers. During the rectification and purification of germanium tetrachloride, waste gas containing chlorine, gaseous hydrochloric acid and gaseous germanium tetrachloride will be produced. Chlorine gas is highly toxic and harmful to humans. There are serious hazards to the environment and the environment. Gaseous hydrochloric acid can produce acid mist to pollute the environment and endanger people’s health. Gaseous germanium tetrachloride meets water to generate hydrochloric acid and release heat, which seriously pollutes the environment and greatly endangers people’s health. If it is directly Emission of these exhaus...
