Application of Industrial Filter Cloth in Horizontal Vacuum Belt Filter —— Phosphoric Chemical Hemihydrate Gypsum Treatment
1. Solid-Liquid Separation Challenges of Phosphoric Chemical Hemihydrate Gypsum
During phosphoric chemical production, a large amount of hemihydrate gypsum ( CaSO ₄ · 0.5H ₂ O ) is produced, with a moisture content generally between 30%-40% Hemihydrate gypsum appears as a fine particle suspension slurry. If not dewatered promptly, it will directly affect subsequent transportation, storage, and utilization. Traditional dewatering methods such as plate and frame filter presses or settling tanks have issues like low processing efficiency, high energy consumption, and large footprint.
The horizontal vacuum belt filter, with continuous operation, automated control, and high dewatering efficiency, has become the ideal equipment for solid-liquid separation of hemihydrate gypsum in the phosphoric chemical industry.
2. Process Principle of Horizontal Vacuum Belt Filter
The horizontal vacuum belt filter mainly consists of the filter main machine, slurry distribution system, vacuum system, filter cloth, and auxiliary equipment. Its core workflow is as follows:
- Slurry Transport and Uniform Distribution
The hemihydrate gypsum slurry is transported by a slurry pump to the distribution trough and spread evenly on the filter cloth surface through a distribution device, forming a stable filter layer. - Vacuum Filtration and Filter Cake Formation
The filter cloth passes through the vacuum zone, where negative pressure draws out the filtrate, and particles deposit on the filter cloth surface to form a filter cake. The pore size and material of the filter cloth directly determine the filtrate permeability and filter cake compactness. - Filter Cake Washing and Dewatering
For processes requiring further removal of impurities or salts, a washing spray device can be installed on the filter cloth to wash the filter cake surface with cleaning liquid while maintaining the filter cake structure intact. - Filter Cake Discharge and Filter Cloth Regeneration
The filter cake is discharged by scrapers, vibration, or airflow. The filter cloth is cleaned by water spray or scraper and reused, enabling continuous production.
The continuity and automation of the horizontal vacuum belt filter process give it significant advantages in high-output phosphoric chemical production lines.
3. Key Role of Industrial Filter Cloth in Gypsum Treatment
As the core component of the horizontal vacuum belt filter, the performance of the filter cloth directly affects the overall dewatering efficiency and economy. For phosphoric chemical hemihydrate gypsum, industrial filter cloth mainly considers the following factors:
- Chemical Corrosion Resistance
The hemihydrate gypsum slurry contains certain acidity and salts; the filter cloth must have excellent acid and alkali resistance to ensure long-term stable operation. - Pore Size and Filtration Precision
The filter cloth pore size is usually selected as 10–50 microns, effectively retaining gypsum particles while ensuring rapid filtrate passage, balancing filtration efficiency and filter cake dryness. - Mechanical Strength and Abrasion Resistance
The filter cloth is subjected to friction and tension during high-speed operation and filter cake discharge. It should have high tensile strength, tear resistance, and abrasion resistance to extend service life. - Filter Cake Release Property
The filter cloth surface must ensure easy filter cake detachment to avoid clogging or production decline due to adhesion.
Based on these requirements, industry-leading companies like Xiamen Citius provide customized filter cloth solutions, including polyester, polypropylene, and composite monofilament filter cloths, to meet different gypsum treatment conditions.
4. Application Advantages and Economic Benefits
The advantages of combining horizontal vacuum belt filters with high-performance industrial filter cloth in phosphoric chemical hemihydrate gypsum treatment mainly include:
- High Dewatering Efficiency
Reasonable filter cloth design and uniform pores significantly reduce filter cake moisture content, improve drying efficiency, and lower subsequent energy consumption. - Continuous Production and Automated Control
Integration of filter cloth and mechanical design enables continuous slurry distribution, dewatering, and filter cake discharge, reducing manual operation and ensuring production line stability. - Durability and Economic Efficiency
High-quality filter cloth materials are wear-resistant and corrosion-resistant, reusable, reducing production costs and equipment maintenance expenses. - Strong Process Adaptability
Customizable design for hemihydrate gypsum with different moisture contents and particle sizes to meet various production line requirements.
5. Industry Practice Case
In the production line of a leading domestic phosphoric chemical enterprise, horizontal vacuum belt filters combined with Citius industrial filter cloth are used for hemihydrate gypsum treatment:
- Production Increase Single machine daily output can reach 50–100 Tons, continuous stable operation.
- Filter cake dryness optimization : Discharge filter cake moisture content below 15% , significantly higher than traditional plate and frame filter presses.
- Filter cloth lifespan extension : Using high wear-resistant monofilament composite filter cloth, the service life is extended compared to traditional filter cloth. 2–3 times.
- Environmental and energy consumption improvement : Reduce emissions and cleaning water usage, lower energy consumption, and achieve green production.
This case demonstrates that the combination of high-performance industrial filter cloth and advanced horizontal vacuum belt filter can significantly optimize the solid-liquid separation process of phosphogypsum in the phosphate chemical industry.
6. Summary and Outlook
The application of industrial filter cloth in horizontal vacuum belt filters not only improves the dehydration efficiency of phosphogypsum in the phosphate chemical industry but also enhances the automation level and economic benefits of the entire production line.
For phosphate chemical enterprises, choosing the right combination of industrial filter cloth and horizontal vacuum belt filter will become an important means to improve production efficiency, reduce costs, and achieve green manufacturing.
