[0002] The treatment of waste sulfuric acid mainly includes processes such as waste sulfuric acid concentration, high-temperature pyrolysis, chemical oxidation, extraction, crystallization, production of chemical fertilizers, and neutralization treatment. Each enterprise generally adopts different treatment processes according to the amount of waste sulfuric acid, the concentration of waste sulfuric acid, the composition and content of impurities, and the use of sulfuric acid after treatment. Sometimes, several processes need to be used in combination. Among these methods, only the neutralization treatment method cannot regenerate sulfuric acid. The treatment of waste sulfuric acid is mainly to remove impurities in the waste sulfuric acid and at the same time concentrate the sulfuric acid.

The utility model includes a waste acid tank, a PP bag filter, a cascade nanofiltration membrane, an acid retardation resin tank, and a purified acid tank connected in sequence. A filtration booster pump is connected between the waste acid tank and the PP bag filter. The waste acid in the waste acid tank of the utility model is physically filtered through three levels of a PP bag filter, a cascade nanofiltration membrane, and an acid retardation resin tank. The filtered acid water is stored in the purified acid tank and can be recycled. It can specifically remove metal ions and other impurities in the acid-containing liquid, can be recycled, directly reduce pollutant emissions, reduce the operating costs of enterprises, and save the consumption of non-renewable resources.

[0004] After the waste acid water liquid is treated in the circulation tank, it needs to be cooled down before the next operation can be carried out. However, the natural cooling method is time-consuming and laborious, with low efficiency, and is not conducive to ensuring the treatment effect of waste acid.

[0005] Therefore, a circulation tank with a cooling function for waste acid treatment is proposed. Content of the Utility Model
