Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pickling equipment, and particularly relates to a pickling tank with acid mist sealing. BACKGROUND

[0002] After heat treatment, a layer of hard and brittle iron oxide scale is formed on the surface of a semi-finished steel pipe. In order to ensure the quality of the steel pipe, the iron oxide scale needs to be removed. At present, the most commonly used method is to remove the iron oxide scale by pickling. However, pickling will produce acid mist and has strong corrosiveness. The emission of acid mist will cause acid mist and acidic gas to diffuse in the air of the workplace, and after being discharged into the atmosphere, it will also cause acid deposition in the atmospheric environment. It not only endangers the health of workers and residents around the factory, corrodes factory equipment and precision instruments, causes production and life losses, but also has adverse effects on the survival of crops and other plants and animals, causes damage to buildings, etc.

[0003] In order to solve the problems existing in the prior art, people have carried out long-term exploration and proposed various solutions. For example, Chinese patent document discloses a steel pipe pickling hydrochloric acid tank [202021658762.8], which comprises a hydrochloric acid tank body arranged on the ground, a cover arranged on the hydrochloric acid tank body, an isolation groove arranged at the outer edge of the upper opening of the hydrochloric acid tank body, and a blocking strip arranged at the lower edge of the cover. The top of the hydrochloric acid tank body is open. The cover completely covers the isolation groove and the hydrochloric acid tank body surrounded by the isolation groove in plan view. The isolation groove is provided with sealing liquid. When the cover is closed to the upper end opening of the hydrochloric acid tank body, the blocking strip is inserted into the isolation groove and contacts the sealing liquid in the isolation groove.

[0004] The above-mentioned scheme solves the problem of existing acid mist emission to the environment to some extent, but the scheme still has many deficiencies, for example, the isolation groove of the hydrochloric acid tank is only sealed by the sealing liquid, which is easy to cause acidification of the sealing liquid and poor sealing effect.
