Description

TECHNICAL FIELD

[0001] The utility model belongs to pickling tank technical field, and specifically relates to a pickling tank with acid mist recovery function. BACKGROUND

[0002] Quartz sand is a common mineral and is used in many industries, but it often contains impurities such as iron oxides, other oxides, yellow skin, and water rust. These impurities seriously affect the purity and quality of quartz sand and need to be treated by pickling. Pickling can remove oxides from quartz sand. The acid reacts with the oxides to produce soluble salts, thereby removing the oxides from the quartz sand. In addition, pickling can also remove impurities such as yellow skin, water rust, and organic stains on the surface of quartz sand.

[0003] In the prior art, quartz sand is usually pickled and purified using a pickling device, such as a pickling tank. A large amount of quartz sand is poured into the pickling tank for soaking and pickling treatment. However, strong acid is usually used during the pickling of quartz sand, and acid mist is easily generated during the pickling process. If these acid mists are not promptly recovered and treated, they will spread to the surrounding environment, causing harm to the health of workers and posing a significant safety hazard. Although the utility model with the patent announcement number CN211445912U discloses a pickling tank with acid mist recovery function, it is designed for metals and removes the thin film on the surface of the metal. Therefore, a pickling tank with acid mist recovery function for pickling quartz sand needs to be designed. SUMMARY
