Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled acid wastewater, in particular to a cold-rolled acid wastewater treatment device. Background Technique

[0002] Cold rolling uses hot-rolled steel coils as raw materials. After pickling to remove the oxide scale, cold tandem rolling is carried out. Its finished product is cold-rolled hard coil. Due to the work hardening caused by continuous cold deformation, the strength and hardness of the cold-rolled hard coil increase, and the toughness and plasticity indexes decrease. Therefore, the stamping performance will deteriorate, and it can only be used for parts with simple deformation. The cold-rolled hard coil can be used as the raw material of the hot-dip galvanizing plant because the hot-dip galvanizing unit is equipped with an annealing line. The weight of the cold-rolled hard coil is generally 6-13.5 tons. The steel coil is continuously rolled at room temperature for the hot-rolled pickled coil. The inner diameter is 610mm. Acid wastewater is wastewater with a pH value less than 6, mainly from the wastewater discharged by enterprises such as metallurgy, metal processing, petrochemical, chemical fiber, and electroplating; alkaline wastewater is wastewater with a pH value greater than 9, mainly from industries such as papermaking, leather making, oil refining, petrochemical, and chemical fiber. Acid-base wastewater entering the water body will destroy the natural neutralization effect, change the pH value of the water body, affect the normal growth of aquatic organisms, and reduce the self-purification function of the water body.

[0003] However, the existing cold-rolled acid wastewater treatment has the following disadvantages:

[0004] (1) For the existing cold-rolled acid wastewater treatment, the function of filtering and treating impurities is weak. When in use, alkaline substances are usually added during the treatment of cold-rolled acid wastewater, resulting in the generation of precipitates inside the cold-rolled acid wastewater treatment device. Since the precipitates will accumulate more and more, the precipitates inside the treatment device cannot be cleaned, affecting the subsequent wastewater treatment.

[0005] (2) For the existing cold-rolled acid wastewater treatment, the mixing function is weak. When in use, alkaline substances need to be added into the treatment device for reaction to remove the acidity in the acid wastewater so that the wastewater can be treated normally. However, the conventional static mixing reaction time is long and the reaction effect is poor, resulting in low efficiency of cold-rolled acid wastewater treatment. Content of the Utility Model
