Citius | The application of industrial filter cloth in the steel industry level vacuum filter for processing desulfurization gypsum from sintering plants
Release time:
2024-11-27
1. Background Overview
In the production process of sintering plants in the steel industry, desulfurization processes are usually employed to purify flue gas in order to reduce sulfur dioxide emissions. A byproduct generated during the desulfurization process is desulfurization gypsum, which mainly consists of calcium sulfate dihydrate. Due to the high moisture content and impurities in desulfurization gypsum, efficient solid-liquid separation equipment is required for dehydration and purification treatment to facilitate subsequent resource utilization.
Horizontal vacuum belt filters are widely used in the dehydration of desulfurization gypsum in the steel industry due to their large processing capacity, high degree of automation, and stable operation, while high-performance industrial filter fabrics are the key core components for achieving efficient separation.
2. Equipment and Process Characteristics
1. Characteristics of Horizontal Vacuum Belt Filters
Continuous Operation: It can achieve continuous feeding, filtering, washing, discharging, and filter cloth regeneration of desulfurization gypsum;
High Filtration Efficiency: Quickly removes moisture from gypsum slurry through vacuum suction and mechanical action;
Flexible Adaptability: Operating parameters can be adjusted according to the material properties of gypsum to meet different working conditions.
2. Process Flow
Feeding and Distribution: Uniformly distribute the desulfurization gypsum slurry on the surface of the filter cloth;
Vacuum Dehydration: Utilize negative pressure formed by the vacuum system to separate moisture from the slurry through the filter cloth;
Filter Cake Washing: Further remove impurities to improve the purity of desulfurization gypsum;
Discharge and Cleaning: The filter cake is removed by mechanical scrapers, and the filter cloth is regenerated and cleaned to maintain continuous operation of the equipment.
3. Key Role of Industrial Filter Fabrics
The industrial filter fabrics developed by Xiamen Citius provide an efficient solution for the treatment of desulfurization gypsum in the steel industry.
1. Filter Fabric Performance Requirements
Chemical Corrosion Resistance: Desulfurization gypsum contains acidic or alkaline substances, so the filter fabric must have strong corrosion resistance;
Fine Filtration: Precisely control the pore size of the filter fabric to ensure efficient retention of solids in the slurry;
Anti-Clogging Properties: Use special surface treatment technology to reduce the frequency of filter fabric clogging;
Long Service Life: The material of the filter fabric is highly wear-resistant and can operate for a long time under high load conditions.
2. Product Technical Features
Specialized Weaving Technology: Optimize fiber arrangement to enhance breathability and filtration performance;
Customized Services: Design filter fabric specifications tailored to customer equipment parameters and slurry characteristics;
Efficient Regeneration Cleaning: The filter fabric maintains high filtration efficiency even after multiple cleanings, reducing replacement frequency.
4. Application Case Analysis
In a certain steel enterprise's sintering plant, Xiamen Citius industrial filter fabrics were applied in horizontal vacuum belt filters, successfully completing the dehydration task for desulfurization gypsum, achieving the following results:
Significantly Improved Dehydration Efficiency: The moisture content of the filter cake was reduced from the original 40% to 25%;
Reduced Operating Costs: The replacement cycle of the filter fabric was extended by 30%, saving approximately 20% in annual operating costs;
Promotion of Resource Utilization: The purity of desulfurization gypsum was improved, making it suitable for producing building materials such as gypsum boards and cement retarders;
Enhanced Environmental Benefits: Reduced waste emissions, promoting the achievement of environmental protection goals in sintering plants.
5. Outlook and Summary
: With increasingly stringent environmental regulations, the requirements for desulfurization gypsum treatment in steel industry sintering plants are gradually increasing. The combination of horizontal vacuum belt filters and high-quality industrial filter fabrics not only improves dehydration efficiency but also provides possibilities for comprehensive utilization of byproducts. Xiamen Citius will continue to provide efficient and stable filtration solutions for the steel industry with its leading technology and rich experience, supporting green transformation and sustainable development in the industry.
