High-temperature resistant and high-efficiency air filter
High-temperature resistant and high-efficiency air filterThe following is a detailed introduction to high-temperature resistant and high-efficiency air filters:Structure and Material Filter material: Usually, glass fiber or superfine glass fiber filter paper is used, which has excellent high-temperature resistance and can effectively intercept particles larger than 0.3μm. It has a good filtering effect on PM2.5, bacteria, cooking fumes, etc. Partition: Generally, aluminum foil partitions are used. Their arc-shaped corrugated grooves and peaks not only protect the filter paper but also allow the wind speed to pass through evenly, reducing resistance. Outer frames: Common types include stainless steel outer frames, galvanized iron frames, and aluminum alloy frames. The stainless steel outer frame has high strength and strong corrosion resistance and is suitable for damp and corrosive environments. Galvanized iron frames have a relatively low-cost and high-cost performance. Aluminum alloy frames are characterized by lightweight and corrosion resistance, making them suitable for places such as laboratories and precision instrument rooms. Sealant: Special high-temperature resistant sealants, such as red high-temperature silicone resistant to 250℃ and black high-temperature inorganic sealant resistant to 350-400℃, can ensure the filter's sealing performance in high-temperature environments and prevent leakage. Working principle Interception and screening: Separation is based on the size of the particles. The pore size of the filter material determines the size of the particles that can be intercepted. When air passes through the filter material, particles larger than the pores are directly intercepted. Surface capture: Even if the particle size is smaller than the pores of the filter material, it may still be captured by colliding with the surface of the filter material due to Brownian motion, van der Waals forces, and other effects. Adsorption effect: Particles adhere to the filter under the influence of chemical/electrical charges, thereby effectively removing pollutants from the air. Performance characteristics High-temperature resistance: It can operate stably in high-temperature environments, with a maximum instantaneous temperature of up to 300 degrees Celsius and a constant temperature of around 260 degrees Celsius. Some specially designed filters can even withstand temperatures ranging from 350 to 400 degrees Celsius. High filtration efficiency: It comes in various efficiency specifications such as H10 to H14, which can meet the air cleanliness requirements of different places. Under the rated air volume, it can achieve a filtration efficiency of 99.99% at 0.3um. Low resistance: The reasonable structural design and high-quality filter material result in relatively low resistance when air passes through the filter, which not only ensures the air flow rate but also reduces energy consumption. Large dust holding capacity: The larger filtration area and excellent filter material performance enable the filter to have more dust particles, extending the replacement cycle and reducing the usage cost. Application field Industrial field: It is used in the chemical industry, high-temperature coating lines, welding workshops, boiler rooms, etc. It can effectively filter high-temperature smoke and dust, harmful gases, etc., protecting the health of equipment and workers. The electronic semiconductor industry: In the processes of semiconductor manufacturing and wafer production, extremely high air cleanliness is required. High-temperature-resistant and high-efficiency air filters can ensure that the production environment is not polluted and improve product quality. Pharmaceutical industry: It is suitable for high-temperature sterilization equipment in pharmaceutical factories, clean baking rooms, drug production workshops, etc., which can prevent contamination by bacteria, viruses, and other microorganisms and ensure the quality of drugs. In the food industry, places such as food baking equipment and food processing workshops can filter out dust, bacteria, and other impurities in the air, ensuring the hygiene and safety of food. In the field of scientific research, high-temperature experimental equipment in laboratories, precision instrument rooms, etc., require the use of high-temperature resistant and high-efficiency air filters to protect the instruments and equipment and ensure the accuracy of experimental results. |
