Problems solved by technology
However, the rust removal operation through the pickling line also has certain shortcomings. During the rust removal process, pollution problems such as acid mist and pickling waste liquid are generated, and the environmental protection is relatively strong. With a greater suppression effect, the generation of acid mist has been greatly reduced, but it is still unable to completely suppress the generation of acid mist. The pickling line is at the exit of the steel strip, and a certain amount of acid mist is often brought out, as well as from the equipment connection. Leakage of acid mist, especially when the acid mist recovery tower fails, a large amount of acid mist will escape from the outlet of the steel belt, causing the surrounding environment and equipment to be corroded to varying degrees

The invention discloses a steel strip purging and pickling device. The device comprises a pickling tank, wherein an opening is formed in one end of the pickling tank, and an outlet is formed in the other end of the pickling tank; a transmission roller set is arranged between the opening and the outlet, and a steel strip is arranged on the transmission roller set; acid mist spraying devices are arranged at the upper end and the lower end of the transmission roller set, and a plurality of acid mist outlets are formed in the pickling tank; the acid mist outlets are connected with an exhaust pipe, and each acid mist spraying device comprises a plurality of mist spraying heads and an air spraying opening; and the mist spraying heads and the air spraying openings are in interval distribution. Through the manner, the steel strip purging and pickling device can comprehensively carry out pickling on the steel strip, and acid mist is prevented from being leaked; and the device is simple in structure, safe and reliable.
Description
technical field [0001] The invention relates to the field of steel strip pickling, in particular to a steel strip purging and pickling device. Background technique [0002] At present, the derusting of steel strip is mainly carried out by physical method and chemical method, among which, the chemical method is used for derusting by pickling line, which has fast derusting speed and thorough derusting, and is welcomed by the steel strip rolling processing industry. However, the rust removal operation through the pickling line also has certain shortcomings. During the rust removal process, pollution problems such as acid mist and pickling waste liquid are generated, and the environmental protection is relatively strong. With a greater suppression effect, the generation of acid mist has been greatly reduced, but it is still unable to completely suppress the generation of acid mist. The pickling line is at the exit of the steel strip, and a certain amount of acid mist is often b...
