2025-03-17

Construction material fly ash is a fine particulate matter generated during the production process of the construction materials industry. It has a high moisture content and is difficult to dehydrate, which has a certain impact on the environment and production efficiency. In order to efficiently handle this type of material, horizontal vacuum belt filter is favored in the industry due to its continuous operation, efficient dehydration, and high degree of automation, making it a commonly used solid-liquid separation equipment. In this process, the industrial filter cloth is a key factor in determining the filtration effect. Industrial filter cloths suitable for filtering construction material fly ash need to have characteristics such as high temperature resistance, corrosion resistance, good water permeability, and wear resistance, to ensure efficient filtration, low moisture content of the filter cake, and stable operation of the equipment. Xiamen Citius, as a leading brand in the industrial filtration materials industry, researches and provides high-performance filter cloths, specially designed for horizontal vacuum belt filter. Its filter cloth solutions can improve filtration efficiency, extend service life, and reduce operating costs. They have been widely used in the construction materials industry, helping enterprises achieve green environmental protection and efficient production.

I. Sources and Treatment Needs of Building Material Powder Fly Ash

1. Formation of Building Material Powder Fly Ash

Building material powder fly ash is a fine particulate matter generated during the production and use of building materials. It typically originates from the grinding, burning, and drying processes of raw materials such as cement, lime, gypsum, and mineral slag powder. These dusts or ash slags have a small particle size, and some materials may contain incompletely burned carbonaceous substances or other impurities under high-temperature conditions, making their filtration and separation more difficult.

Building material powder fly ash not only affects the cleanliness of the production environment but may also pollute the atmosphere, soil, and water resources. Therefore, efficient filtration and solid-liquid separation processes must be adopted to reduce its water content and improve the efficiency of resource utilization.

2. Key Difficulties in Treating Building Material Powder Fly Ash

  • Fine Particles, Easy Clogging：Building material powder fly ash particles are typically less than100micrometers, easily forming an adhesion layer on the filter medium, reducing filtration efficiency.
  • High-Temperature Characteristics：Some fly ash is formed in high-temperature environments and has a high temperature, requiring filter materials with high-temperature resistance.
  • High Water Content, Difficult Dehydration：Building material powder fly ash produced in certain processes may have a high water content, requiring efficient dehydration equipment to reduce the water content and improve filter cake quality.
  • High Abrasion Resistance Required：The tiny particles in the fly ash cause continuous friction on the filter cloth during filtration, which may lead to wear and tear of the filter cloth, affecting filtration efficiency and equipment life.

II. Application of Horizontal Vacuum Belt Filter in the Treatment of Building Material Powder Fly Ash

1. Working Principle of Horizontal Vacuum Belt Filter

The horizontal vacuum belt filter is a highly efficient solid-liquid separation equipment suitable for solid-liquid separation needs in large-scale industrial production. Its main working principle is as follows:

  • Material Feeding：The fly ash slurry is evenly distributed on the running filter cloth through the slurry distribution device.
  • Vacuum Dehydration：While the filter cloth moves the slurry, the vacuum box at the bottom provides negative pressure, allowing the liquid to quickly permeate the filter cloth to form filtrate, while the solid particles are retained by the filter cloth to form a filter cake.
  • Filter Cake Washing (Optional)：If the material needs further purification, a cleaning liquid can be sprayed onto the filter cake for secondary washing.
  • Filter Cake Discharge：The dehydrated filter cake is automatically peeled off by a scraper or reversing device, thus achieving continuous operation.
  • Filter Cloth Regeneration：During the circulation process, the filter cloth is cleaned by a high-pressure spray or vibration cleaning system to remove the attached fine particles and ensure the filtration effect of the next round.

2. Advantages of Horizontal Vacuum Belt Filter

  • Efficient Dehydration, Reduced Water Content：Vacuum adsorption allows the filter cake to form quickly, while reducing residual moisture and improving the dryness of the building material powder fly ash.
  • Continuous Operation, Improved Production Efficiency：Compared with traditional batch filtration equipment, the horizontal vacuum belt filter can achieve continuous operation to meet the needs of large-scale production.
  • Adaptable to Various Materials：The equipment can adjust operating speed, vacuum degree, and other parameters to adapt to the filtration needs of different building material powder fly ash.
  • Reduced Manual Intervention, Lower Operating Costs：High degree of automation can significantly reduce manual operation costs and improve production stability.

III. The Key Role of Industrial Filter Cloth in Horizontal Vacuum Belt Filter

1. Core Factors Affecting Filtration Effect

In the operation of the horizontal vacuum belt filter, the filter cloth is the key component that determines the filtration effect, filter cake quality, and equipment stability. Selecting the appropriate filter cloth can improve dehydration efficiency, reduce filter cake water content, and extend the service life of the equipment.

2. Performance Requirements of Industrial Filter Cloth in Building Material Powder Fly Ash Filtration

  • High-Temperature Resistance：Some fly ash is formed in high-temperature environments, and the filter cloth needs to have high-temperature resistance to prevent performance degradation due to thermal aging.
  • Chemical Corrosion Resistance：Some building material fly ash may contain alkaline or acidic components, and the filter cloth needs to have strong chemical resistance to prevent performance degradation after long-term use.
  • Excellent Water Permeability and Solid Retention Rate：Reasonable pore size distribution ensures that the liquid passes quickly while effectively retaining fine particles, improving the dryness of the filter cake.
  • High Strength and Abrasion Resistance：Fly ash particles move at high speed on the surface of the filter cloth, easily causing wear and tear of the filter cloth, so high-strength, abrasion-resistant fiber materials are needed to extend the service life of the filter cloth.
  • Good Filter Cake Peelability：The filter cloth should have excellent surface properties to reduce filter cake adhesion, facilitate smooth filter cake peeling, and improve filtration efficiency.
