Description

Technical Field

[0001] The utility model relates to the field of phosphogypsum washing, in particular to a phosphogypsum washing liquid processing device. Background Art

[0002] Phosphogypsum washing liquid is an important link in the treatment of phosphogypsum. Phosphogypsum is a by-product of the phosphorus chemical production process. Its main component is calcium phosphate, and it also contains a small amount of harmful substances. Under the requirements of environmental protection and resource recycling, phosphogypsum needs to be processed before it can become a usable resource.

[0003] During the washing process, phosphogypsum is mixed with water, and the harmful substances in the phosphogypsum are transferred to the washing liquid through chemical reactions and physical actions, thereby achieving the purification of the phosphogypsum. The washing liquid contains useful and harmful components in the phosphogypsum, such as phosphates, heavy metal ions, etc. Therefore, the washing liquid needs to be treated to facilitate the use of the washing liquid to wash the phosphogypsum multiple times.

[0004] However, the current washing liquid treatment device uses activated carbon for adsorption treatment when treating the washing liquid. After being used for a long time, the activated carbon needs to be replaced. However, the current treatment device has the problem of difficult replacement because the activated carbon is arranged inside the treatment device and is in a fixed installation as a whole, resulting in the adsorption capacity of the activated carbon being reduced after long-term use.
