Abstract

The invention discloses an anti-fogging system and method used for hydrochloric acid discharge. The system comprises a hydrochloric acid storage tank, a conveying pump, an absorption tower, a circulating pump, a water source device and an overhead tank. Acid mists generated during acid discharge can be exhausted into the absorption tower, and are absorbed by water in the absorption tower; absorption liquor obtained by absorbing the acid mists can be used for preparing diluted hydrochloric acid with concentration being 2 mol / L, so that harms due to the fact that acid mists generated in a hydrochloric acid discharge process are volatilized into air can be effectively avoided; during acid introduction, a fog accommodating space is reserved over hydrochloric acid in the hydrochloric acid storage tank, and acid discharge speed is controlled to be firstly slow and then quick, so that generation amount of acid mists in the acid discharge process can be effectively reduced; and moreover, the anti-fogging system facilities exhausting acid mists into the absorption tower to absorb, so that harms due to that fact acid mists generated in the hydrochloric acid discharge process are volatilized into air can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of unloading hydrochloric acid, in particular to an anti-atomization system and method for unloading hydrochloric acid. Background technique [0002] Hydrochloric acid is an aqueous solution of hydrogen chloride gas, which is a monobasic inorganic strong acid and has a wide range of industrial uses. The properties of hydrochloric acid are colorless and transparent liquid with a strong pungent smell and high corrosiveness. Concentrated hydrochloric acid is extremely volatile, so when the container containing concentrated hydrochloric acid is opened, hydrogen chloride gas will volatilize and combine with water vapor in the air to produce small hydrochloric acid droplets, causing acid mist to appear above the bottle mouth. [0003] In the industrial field, hydrochloric acid is usually transported to the plant by train tanker or car tanker, and the hydrochloric acid is unloaded into the hydrochloric acid storag...
