Cover filter is a device used to filter impurities in liquids, mainly in the field of water treatment. It has a wide range of applications in industries such as power, chemical, pharmaceutical, and food. The following are some common application scenarios:
1. Power industry
Condensed water polishing: In thermal power plants, covered filters are commonly used for the polishing of condensed water. Steam condenses into water after doing work in a steam turbine, which may contain impurities such as metal corrosion products, colloids, and trace amounts of salts. Covering the filter can effectively remove these impurities, achieving high purity of condensed water and meeting the requirements of boiler water replenishment, thereby ensuring the safe and stable operation of the boiler and improving power generation efficiency.
Supply water treatment: For the supply water of power plants, covered filters can be used as pre-treatment equipment to remove suspended solids, organic matter and other impurities in the water, reduce the burden on subsequent ion exchange resin and other deep treatment equipment, extend their service life, and improve the quality of the supply water to ensure that the water entering the boiler meets the water quality requirements.
2. Chemical industry
Chemical raw material liquid refining: In chemical production, many raw materials need to be refined to remove impurities. Cover filters can be used for filtering various chemical raw materials, such as lubricating oil base oil refining in petrochemicals and polyester raw material liquid filtration in chemical fiber production. By filtering and removing impurities such as solid particles and colloids from the raw material liquid, the purity of the raw material liquid can be improved, which helps to ensure the quality of the product and the stability of the production process.
Chemical wastewater treatment: Chemical wastewater has complex components and contains a large amount of pollutants such as suspended solids, organic matter, and heavy metal ions. Covering filters can serve as an intermediate step in the treatment of chemical wastewater. After preliminary sedimentation, coagulation, and other pretreatment processes, they further remove small particles and some organic matter from the wastewater, creating favorable conditions for subsequent deep treatments such as biological treatment and membrane separation, improving the treatment efficiency of wastewater, and meeting discharge standards or reuse requirements.
3. Pharmaceutical industry
Preparation of injection water: In pharmaceutical production, especially in the production process of drugs such as injections that require high water quality, covering filters are one of the key equipment for preparing injection water. It can effectively remove impurities such as bacteria, viruses, pyrogens, and particles from water, ensuring that the quality of injection water meets pharmacopoeia standards and guaranteeing the safety and effectiveness of drugs.
Liquid filtration: In the process of drug production, various liquid medicines may introduce impurities during preparation, concentration, crystallization, and other stages. Covering filters can be used to filter the liquid medicines, remove insoluble impurities, improve the purity of the liquid medicines, and ensure the stability of drug quality.
4. Food industry
Beverage production: In beverage production, such as mineral water, purified water, fruit juice, carbonated beverages, etc., covered filters can be used to remove suspended solids, colloids, microorganisms and other impurities in water, improve water clarity and hygiene indicators, and ensure the taste and quality of beverages. Meanwhile, in the production process of juice and other beverages, it can also be used to filter impurities such as fruit pulp fibers and pectin in the juice, making the beverage clearer and more transparent.
Brewing industry: In the brewing process of beer, wine, Baijiu, etc., the cover filter can be used to filter yeast, bacteria, protein and other impurities in the fermentation liquid, improve the clarity and stability of the wine, and improve the appearance and taste of the wine. In addition, during the treatment of brewing water, a cover filter can also be used to remove impurities from the water and ensure the quality of brewing water.
