Product Description Multi-Disc FilterParameterProduct Photo Overview: The multi-disk filter is an efficient solid-liquid separation equipment widely used in the pulp and paper industry, mainly for processes such as pulp washing, concentration, fiber recovery, and black liquor extraction. Its design combines the principles of vacuum filtration and continuous rotation, enabling efficient handling of slurry, improving pulp purity, and enhancing production efficiency.Design Principle: In the pulp and paper process, the multi-disk filter achieves pulp washing and concentration through the following steps:Pulp Filtration: Multiple filter disks rotate around a central shaft, with some of the disks submerged in the slurry tank. Under vacuum pressure, the liquid in the slurry passes through the filter cloth, while solid fibers are retained on the surface of the filter cloth, forming a filter cake.Black Liquor Recovery: As the disks rotate, the black liquor in the filter cake is gradually extracted and enters a vacuum channel for recovery, which is then reused for chemical processes.Filter Cake Removal: After the disk leaves the slurry tank, the filter cake is further dried in a dewatering area, and it is removed by a scraper or a reverse air-blow device, completing the cycle.Technical Features:Efficient Pulp Concentration and Washing: The multi-disk design significantly increases the filtration area, enabling fast slurry concentration and washing, which improves pulp purity.Efficient Black Liquor Recovery: In chemical pulping processes, black liquor chemicals (such as alkali) are effectively recovered, reducing production costs.Vacuum Negative Pressure Operation: Vacuum suction provides stable power, ensuring efficient pulp washing while reducing energy consumption.Continuous and Stable Operation: Filtration, dewatering, and discharge processes occur simultaneously, enabling continuous production to meet the demands of large pulp production lines.Compact Structure and Space Saving: The equipment occupies a small area, making it suitable for new installations or upgrades of pulp and paper production lines.Low Maintenance Cost: Key components are made of wear-resistant, corrosion-resistant materials, extending the service life of the equipment and reducing downtime and maintenance time.Applications:Pulp Concentration: In mechanical pulping, chemical pulping, or waste paper pulp processing, low-concentration slurry is concentrated to the required concentration for further treatment.Pulp Washing: In chemical pulping processes, the pulp is washed to remove impurities and dissolved black liquor, improving pulp quality.Black Liquor Recovery: Efficient recovery of alkaline black liquor chemicals reduces alkali recovery costs and minimizes environmental pollution.Fiber Recovery: Recovering fibers from pulp wastewater reduces fiber loss and enhances resource utilization.Summary of Advantages: In the pulp and paper industry, the multi-disk filter is an indispensable core equipment in the pulping process due to its high efficiency in pulp concentration, washing, and black liquor recovery. Its features, such as large filtration area, low energy consumption, and continuous operation, significantly improve pulp production efficiency and reduce production costs, making it an ideal choice for environmentally friendly and efficient production.Our company also offers semi-customized and fully customized solutions.
