Working principle of pulverized coal filter

       Xiangye Environmental Protection editor details the working principle of the pulverized coal filter. Although it is compact in size, its design is sophisticated and powerful. It is installed after the air supplement regulator of the pulverized coal main pipeline at the outlet of the injection tank and is a key device to prevent clogging in the pulverized coal conveying pipeline. Through wear-resistant filter plates, this filter separates impurities from the pulverized coal, ensuring smooth pneumatic conveying of pulverized coal.

       The design principle of the pulverized coal filter produced by our company is simple yet efficient. In industrial applications, pulverized coal filters are widely used in blast furnace pulverized coal injection systems and are key equipment to ensure the continuous and stable operation of the pulverized coal injection system. In blast furnace pulverized coal injection systems, the pulverized coal filter can filter out coarse and large particles as well as impurities in the pulverized coal, preventing these impurities from entering components such as distributors, pulverized coal branch pipes, and valves on the branch pipes, which could cause clogging and damage. The use of the pulverized coal filter not only improves production efficiency but also extends the service life of the equipment and reduces maintenance costs.

      Structurally, the pulverized coal filter is made of carbon steel, with an inner wear-resistant layer that enhances the durability of the equipment. The double cone bodies are butt-welded, and the entire shell interior is designed with stable airflow angles, allowing the pulverized coal to pass through more smoothly, reducing resistance and wear. The middle section consists of a wear-resistant manganese steel filter plate, which offers excellent wear resistance and filtration efficiency, effectively filtering impurities from the pulverized coal. The filter plate is designed to be removable, facilitating maintenance and replacement, significantly reducing equipment downtime and maintenance costs.

      The pulverized coal filter equipment is installed after the air supplement regulator of the pulverized coal main pipeline at the outlet of the injection tank. It is used to filter coarse and large particles, as well as other woven fibers, wood chips, and debris from the pulverized coal, ensuring smooth pneumatic conveying of pulverized coal. This prevents clogging in distributors, spray guns, and valves on branch pipes, ensuring continuous and stable pulverized coal injection. Its compact structure, light weight, and reliable performance make it widely used in various dust pipelines in industries such as metallurgy and petrochemicals.
