Guardian of Pulverized Coal Filtration
In the core area of the coal injection system, a device known as the MGQ-type pulverized coal filter stands like a guardian. It is ingeniously installed after the air supplement regulator in the main coal injection pipeline at the outlet of the injection tank. Its role extends beyond mere filtration, ensuring the smooth and unobstructed pneumatic conveying of pulverized coal.

I. Light of Technology
This equipment is specifically designed to handle pulverized coal, effectively filtering out coarse particles, woven fibers, wood chips, and other impurities. It is suitable for media consisting of a mixture of pulverized coal and nitrogen (or air), with a design temperature of 100°C and design pressures of up to 1.0 MPa, 1.6 MPa, and 2.5 MPa. Notably, its filtration area is at least four times that of the inlet main pipe, ensuring both efficiency and effectiveness in filtration.

II. Form and Character
The MGQ-type pulverized coal filter comes in a variety of外形連接尺寸 (external connection dimensions), with nominal diameters ranging from DN40 to DN150, among other specifications, to meet diverse industrial needs. Its compact structure, lightweight design, and reliable performance make it adept at handling filtration tasks in various dust pipelines and containers, whether in the metallurgical or petrochemical industries.
III. Mission of the Pulverized Coal Filter
Within the entire coal injection system, the pulverized coal filter plays a crucial role. If the blast furnace coal injection system were compared to the human body, the pulverized coal filter would be the internal cleaner. It specializes in removing debris from the conveying pipelines, preventing blockages, and ensuring the smooth pneumatic transport of pulverized coal.

Our company's professionally designed pulverized coal filter is made of carbon steel, with an inner layer equipped with a wear-resistant coating to combat the abrasive nature of coal powder. It features a double-cone butt-welded structure, and the shell interior utilizes specific design angles to create stable airflow. This not only facilitates smoother coal powder passage but also reduces resistance during transit, thereby minimizing wear.
The filter plate is crafted from wear-resistant manganese steel and designed in a detachable format, making daily maintenance and replacement convenient while showcasing unique design and user-friendly considerations. Additionally, its distinctive and compact structural design, large filtration area, and low resistance loss make inspecting and replacing the filter screen remarkably straightforward.

IV. Literary Narration
This device acts like a loyal guardian, silently fulfilling its mission. In the world of coal injection systems, it serves as both a cleaner and an engineer, ensuring the system's normal operation with its unique structure and performance. Whether in a metallurgical workshop or a petrochemical base, it is an indispensable presence.
In summary, the MGQ-type pulverized coal filter has earned widespread acclaim in the industry for its efficient, reliable performance and unique design. It is a faithful partner to the coal injection system and an essential component of industrial production.
