Abstract
Description
Technical Field
[0001] The invention relates to the technical field of industrial hydrochloric acid preparation, and in particular to a three-in-one synthesis furnace and process for by-product steam hydrochloric acid. Background Art
[0002] Hydrochloric acid is the common name for aqueous solution of hydrogen chloride, which is a monobasic inorganic strong acid and an extremely important industrial raw material. When synthesizing industrial hydrochloric acid, firstly, hydrogen and chlorine generated after electrolysis are passed through a quartz burner in a hydrochloric acid synthesis furnace and ignited to generate hydrogen chloride gas, which is then absorbed by water after cooling to become hydrochloric acid. During the hydrochloric acid synthesis process in a hydrochloric acid synthesis furnace, there is often a certain amount of moisture in the chlorine after electrolysis. If it is directly passed into the mixed combustion, it will not only lead to incomplete combustion, but also cause certain safety hazards.
[0003] After searching, it is found that in the prior art, a drying tower is usually required to dry the chlorine before it is passed into the combustion section for combustion. However, water vapor in the air is everywhere, and the chlorine gas coming out of the drying tower still has a distance to reach the combustion section. Therefore, we propose a new industrial hydrochloric acid synthesis furnace that integrates heating, drying, generation, cooling and absorption to improve synthesis efficiency and energy consumption.

At this time, the hydrochloric acid that has reached the standard concentration can be easily pushed to the finished hydrochloric acid discharge pipe 24, and then the valve can be opened to discharge it. After discharge, fill it with pure water for next use. The whole process can release the finished product and add pure water without stopping.
