In industrial scenarios such as steel metallurgy, chemical engineering, and ore crushing, harsh environments with high temperatures, much dust, and high pollution impose strict requirements on equipment filtration systems. This multi-stage industrial filter is specially designed for extreme industrial environments. By combining a stepped filtration structure with high-temperature resistant materials, it efficiently intercepts various industrial pollutants, providing all-round protection for the stable operation of industrial equipment and effectively reducing the risk of equipment wear and failure.
The core advantage lies in the innovative multi-stage filtration system. This system, based on the particle size and characteristics of pollutants, sets up three functional levels: pre-filtration, fine filtration, and deep purification, forming a progressive purification defense line. The pre-filtration stage adopts large-pore stainless steel woven mesh, with the pore size set at 50-100 microns. It mainly intercepts large particle impurities and blocky pollutants in industrial waste gas or fluids, such as iron oxide filings in metallurgical processes and catalyst lumps in chemical reactions, to prevent large particles from impacting and clogging the subsequent precision filtration layer, thereby extending the service life of the entire filtration system. This level adopts a detachable design, which is convenient for regular cleaning and recycling, reducing the cost of use.

The fine filtration stage is the core of the entire system. It adopts a composite filter material structure, which is woven from a mixture of glass fiber and ceramic fiber, and the filtration accuracy can reach 1-5 microns. The addition of glass fiber has enabled the temperature resistance of the filter material to exceed 150℃, while ceramic fiber has enhanced the mechanical strength and wear resistance of the filter material, ensuring stable filtration performance even under the impact of high-temperature gas flow. In response to the common electrostatic adsorption problem in industrial environments, some models incorporate electrostatic separation filtration technology. By setting a 12-kilovolt high-voltage electric field inside the filter material, dust particles become charged and are efficiently adsorbed by the negative electrode plate. The filtration efficiency is 40% higher than that of traditional mechanical filtration, making it particularly suitable for dust recovery and purification treatment in the chemical industry.

The deep purification level is configured with targeted functional filter materials according to the special requirements of different industrial scenarios. In the application of the chemical industry, fiber filter materials impregnated with activated carbon can effectively adsorb volatile organic compounds (VOCs) and toxic and harmful gas components in industrial waste gas, such as benzene, toluene, hydrogen sulfide, etc. In the steel and metallurgical scenarios, the configuration of high-temperature resistant adsorbents can preliminarily adsorb acidic gases such as sulfur dioxide and nitrogen oxides in high-temperature flue gas, reducing the concentration of exhaust gas emissions. In the fluid filtration of the food processing industry, food-grade stainless steel filter materials and food-grade seals are used to ensure that no contaminants are released during the filtration process, meeting food safety standards.
