Description

Technical Field

[0002] Hydrochloric acid is an aqueous solution of hydrogen chloride (HCl) with a wide range of industrial uses. Hydrochloric acid is a colorless, transparent liquid with a strong, pungent odor and high corrosiveness. It is an important industrial chemical widely used in the chemical, metallurgical, pharmaceutical, food, and environmental fields. It plays an important role in metal surface treatment, chemical synthesis, and pH adjustment. The production process of hydrochloric acid typically requires large quantities of storage to meet production line needs. However, during the feeding process of hydrochloric acid into storage tanks, the gas released by the hydrochloric acid may endanger the health of workers. For example, China has disclosed a "feeding device for a hydrochloric acid storage tank" with application number "CN201020540947.9." The feed port is equipped with a delivery pipe extending below the covering layer. This allows the hydrochloric acid to be directly fed below the paraffin covering layer.
