Detailed Description
Serving the Green Aluminum Industry —— Xiamen Citius (Xiamen Citius) Filter cloth assists in efficient filtration of gypsum desulfurization in aluminum power plants
In “ Dual Carbon ” Under the guidance of the policy, green development has become the only way for the aluminum industry to transform and upgrade. With the widespread application of supporting self-owned power plants, the flue gas desulfurization system has also become an important environmental protection facility in the aluminum and electricity co-production. Limestone - The gypsum method, as the mainstream desulfurization process, relies on the technical support of the gypsum dehydration process for its efficient and stable operation. Behind this, a seemingly ordinary but highly technical filter cloth —— is the key to ensuring smooth gypsum dehydration and stable equipment operation.
Among many filtration equipment, Horizontal vacuum belt filter ( HVBF ) Due to its continuous and efficient working characteristics, it is widely used in the dehydration of gypsum desulfurization filter cakes. Xiamen Citius (Xiamen Citius) Environmental Filtration Technology Co., Ltd. With its deep technical accumulation and industry experience, it provides customized filter cloth solutions for the aluminum and electricity industry, becoming a stable partner for many aluminum and electricity plants.
Special challenges of desulfurization gypsum dehydration in aluminum power plants
Aluminum and electricity integrated enterprises use coal as the main fuel for their self-owned power plants, and the flue gas SO ₂ concentration is high, and a large amount of desulfurization gypsum is produced during the wet desulfurization process. These gypsum has the following characteristics:
- High water content, fine particles;
- The proportion of impurities fluctuates greatly, and the content of alkali or fluoride may affect the filtration performance;
- The filter cake is easy to cake and difficult to remove, which easily causes blockage or malfunction of the filter cloth;
- High requirements for filtrate reuse, ensuring clarity;
- Long equipment operation cycle, extremely high requirements for filter cloth durability.
Under such operating conditions, traditional filter cloths are difficult to handle for a long time. Xiamen Citius (Xiamen Citius) developed for the aluminum and electricity industry Gypsum desulfurization special filter cloth has shown significant advantages in many projects.
Specifically HVBF designed Xiamen Citius (Xiamen Citius) Filter cloth: Technical highlights
✅ Strong dehydration ability Using optimized pore structure design to achieve rapid filtration and high filter cake dryness (generally controlled at 10-12% ), reducing the energy consumption of subsequent processing;
✅ Excellent stripping performance Smooth surface, moderate fabric density, filter cake can be smoothly removed, reducing scraper wear and filter cloth scaling;
✅ Resistance to chemical corrosion and mechanical fatigue Adaptable to impurities that may exist in aluminum and electricity flue gas, maintaining long-term operation without deformation or damage;
✅ Patented edge structure processing Directional edging and anti-deviation process to improve the running stability of the filter cloth on the belt filter and prevent filter cloth offset or loss;
✅ Customizable filtrate clarity control scheme Combined with the company's needs for filtrate circulating water, optimize the filter cloth weaving density and material combination to improve the clarification efficiency.
Application case: A stable choice for green aluminum plants
A large-scale aluminum and electricity enterprise in the western region produces one million tons of alumina per year. Its self-owned power plant uses a double-tower desulfurization system, with supporting HVBF equipment running continuously. After introducing Xiamen Citius (Xiamen Citius) gypsum desulfurization special filter cloth, the following results were achieved:
- The filter cloth operating cycle is increased from an average of 25 days to 45 days or more;
- The filter cake moisture content is stably controlled at 11% or so;
- The filtrate clarity meets the reuse standard, reducing wastewater discharge;
- Annual filter cloth replacement frequency is reduced by 40% or more, saving a lot of maintenance costs.
Conclusion: Details of the green aluminum industry “ Cloth ”
Against the backdrop of increasingly stringent environmental regulations, the desulfurization gypsum treatment capacity directly affects the environmental performance and sustainable image of aluminum and electricity enterprises. Xiamen Citius (Xiamen Citius) provides professional industrial filter cloth solutions to meet the high standards of the aluminum and electricity industry, not only optimizing process operation, but also helping enterprises achieve green, efficient, and low-carbon development goals.
