In the complex and precise pulverized coal injection system, the pulverized coal filter plays a crucial role. If the entire pulverized coal injection system is likened to the circulatory system of a living organism, then the pulverized coal filter is the unsung cleaner, responsible for removing impurities from the system, ensuring the purity and efficiency of coal powder transportation. The blast furnace pulverized coal injection system relies on pneumatic conveying technology to accurately deliver coal powder to its destination. However, during this process, the conveying pipelines inevitably face the challenge of blockage by foreign objects. At this point, the pulverized coal filter acts like a loyal guardian, effectively removing impurities from the coal powder through its precise filtration mechanism, ensuring smooth and uninterrupted pneumatic conveying.

       Our company, Lanhao, as a leader in this field, professionally designs and produces a series of high-performance pulverized coal filters. These filters use high-quality carbon steel as the main material, with a wear-resistant layer embedded inside to enhance the durability of the equipment. Their design is unique, featuring flange connections on both sides and a double-cone butt welding process, making the structure not only compact but also stable and reliable. More ingeniously, the interior of the filter housing forms a stable airflow channel through carefully designed angles, allowing coal powder to pass through more smoothly, reducing resistance and wear.

       At the core of the filter, we use a filter plate made of wear-resistant manganese steel. This filter plate is not only hard in texture but also designed to be detachable, greatly facilitating daily maintenance and replacement. Such a design not only ensures filtration efficiency but also improves the maintainability of the equipment, making the entire pulverized coal injection system more stable and reliable. In addition to its excellent structural design, our pulverized coal filter also features a large filtration area and minimal resistance loss. This is thanks to our careful design and layout of the filter mesh plate. The filter mesh plate is not only easy to inspect but also convenient to replace, providing great convenience for users' daily operations.

      In industrial fields such as metallurgy and petrochemicals, the efficient and stable transportation of pulverized coal is a critical guarantee for production continuity. However, during the transportation process, coal powder often mixes with various impurities, such as coarse particles, woven fibers, wood chips, etc. Once these impurities enter the conveying pipeline, they become sources of blockage, severely affecting production efficiency and safety. Therefore, a seemingly inconspicuous but vital piece of equipment—the pulverized coal filter—has become an essential choice in these industrial sectors.

      Our pulverized coal filter, though compact in size, is exquisitely designed and highly functional. It is typically installed after the air supplement regulator at the outlet of the injection tank's main pulverized coal pipeline, serving as a key device to prevent blockages in the coal powder conveying pipeline. Through its wear-resistant filter plate, impurities in the coal powder are effectively separated, ensuring smooth and uninterrupted pneumatic conveying of coal powder. This not only improves production efficiency but also significantly reduces the risk of equipment failure.

    In terms of technical parameters, the MGQ-type pulverized coal filter is suitable for media environments of coal powder + nitrogen (or air), with a design temperature of up to 100°C and design pressures ranging from 1.0MPa, 1.6MPa, to 2.5MPa, among other grades. Its filtration area is more than four times that of the inlet main pipe, ensuring high filtration efficiency. At the same time, we offer a variety of外形連接尺寸 for users to choose from, meeting application needs in different scenarios.

       In summary, our pulverized coal filters and lance systems have won the favor and trust of a wide range of users with their卓越的性能,精湛的工藝, and貼心的設(shè)計(jì). In future development, we will continue to uphold the principles of innovation, practicality, and efficiency, providing users with even higher-quality products and services.
