Description

Technical Field

[0001] This utility model relates to the field of phosphogypsum filtrate treatment technology, specifically a phosphogypsum filtrate treatment device. Background Technology

[0002] Phosphogypsum mainly comes in two colors: grayish-black and grayish-white. It is a solid waste generated during the wet-process phosphoric acid production, and its main component is calcium sulfate dihydrate. The composition of phosphogypsum is complex, containing not only calcium sulfate but also incompletely decomposed phosphate rock, residual phosphoric acid, fluorides, acid-insoluble substances, and organic matter. The presence of fluorine and organic matter has the greatest impact on the resource utilization of phosphogypsum. The indiscriminate dumping and accumulation of phosphogypsum severely damages the ecological environment, polluting groundwater resources and wasting land resources.

[0003] Since phosphogypsum contains 20% to 25% water of crystallization, it is necessary to filter the water of crystallization during the treatment of phosphogypsum to prevent environmental pollution. However, most current filtrate treatment devices require frequent replacement of the filter membrane, which involves disassembling and reassembling the filter membrane each time, making the operation time-consuming and labor-intensive. Therefore, it is necessary to design a phosphogypsum filtrate treatment device that allows for quick replacement of the filter membrane to solve the above problems. Utility Model Content
