Technical Field

[0001] This invention relates to the field of detection, and more specifically to an online liquid-solid two-phase detection system for phosphogypsum. Background Technology

[0002] Phosphogypsum is a by-product of the phosphoric acid and phosphate fertilizer industries. With the continuous development of my country's phosphate fertilizer industry, the stock of phosphogypsum is constantly increasing. However, phosphogypsum contains a large number of polluting and harmful substances and cannot be directly recycled. Therefore, the resource utilization of phosphogypsum has become an essential technology.

[0003] The traditional method for recycling phosphogypsum involves washing it multiple times with water to remove soluble phosphorus and soluble fluorine impurities.

[0004] The above-mentioned phosphogypsum recycling and treatment method only separates soluble impurities in phosphogypsum, without separating insoluble eutectic phosphorus, without analyzing the energy consumption required for separating eutectic phosphorus, and cannot accurately determine whether the treated phosphogypsum can be recycled and reused, thus failing to effectively improve the resource conversion rate of phosphogypsum.
