Applications of industrial filter cloth and filter mesh: Horizontal vacuum belt filter in the phosphate chemical industry, purification of phosphogypsum
Share to
Detailed Description
- Industrial filter cloth Application of filter cloth and mesh in horizontal vacuum belt filter for the phosphate chemical industry, phosphogypsum purification
Filter type: Horizontal vacuum belt filter
Application industry: Phosphate chemical industry
Material description: Phosphogypsum purification
Key applications of industrial filter cloth in the phosphate chemical industry:
—— Horizontal vacuum belt filter promotes efficient phosphogypsum purification
In the phosphate chemical industry chain, phosphogypsum, the main byproduct of wet phosphoric acid production, has long been considered a processing challenge. Today, driven by both comprehensive resource utilization and environmental protection standards, phosphogypsum purification and high-value utilization are becoming the focus of the industry. Horizontal vacuum belt filter with High-performance industrial filter cloth / Filter mesh provides efficient and stable technical support for phosphogypsum purification.
Challenges and needs of phosphogypsum purification
Phosphogypsum often contains impurities such as phosphorus, fluorine, heavy metals, and organic matter, and cannot be directly used in building materials, cement, soil improvement, etc., without treatment. To achieve its purification and dehydration, the following must be met:
- Efficient dehydration : Reduce water content for easy storage and transportation;
- Impurity removal : Reduce harmful components through washing and filtration;
- Continuous and stable process : Adapts to industrial and large-scale processing needs;
- Equipment corrosion resistance, filter material acid and alkali resistance : To cope with harsh chemical environments.
Horizontal vacuum belt filter: Core equipment for industrial purification
This equipment integrates negative pressure filtration, filter cake washing, and continuous operation functions, making it an ideal choice for processing fine-particle, high-water-content materials. Its advantages include:
- Continuous filtration, large processing capacity : Meets the daily output of tens of thousands of tons of byproduct gypsum in the phosphate chemical industry;
- Multi-stage washing : Improves impurity removal rate and promotes gypsum purification;
- Good filter cake formation, high dryness : Easy for stacking or further processing;
- Automatic control, low operating cost : Reduces manual intervention.
Industrial filter cloth and filter mesh: Decisive factors for system performance
In the vacuum belt filtration process, the filter cloth is not only the executor of solid-liquid separation, but also directly affects the filtration efficiency, filtrate quality, and system stability . A filter cloth designed for the phosphate chemical industry environment / mesh should have the following characteristics:
