The pulverized coal filter, despite its compact size, boasts an exquisitely ingenious design and should not be underestimated in functionality. It is firmly positioned on the main pulverized coal pipeline at the outlet of the injection tank, specifically behind the aeration regulator, playing a crucial role in preventing blockages in the coal powder conveying pipeline. Equipped with internal wear-resistant filter plates, this filter precisely removes impurities from the pulverized coal, ensuring smooth pneumatic conveying, much like an unobstructed river.

       When it comes to the MGQ-type pulverized coal filter, this equipment also holds significant importance in the coal powder conveying system. It is cleverly installed downstream of the aeration regulator, with the primary task of eliminating coarse particles, woven fibers, wood chips, and other impurities from the pulverized coal. This prevents blockages in distributors, spray guns, and branch pipe valves, ensuring continuous and stable coal powder injection. The MGQ-type pulverized coal filter is renowned for its compact structure, lightweight design, and excellent performance, making it widely used in dust pipeline filtration in metallurgical, petrochemical, and other industries, where it serves as an indispensable key equipment.

       In terms of technical parameters, this filter is suitable for mixed media of pulverized coal and nitrogen (or air), with a design temperature of up to 100°C. The design pressure covers multiple levels such as 1.0, 1.6, and 2.5 MPa, and its filtration area is more than four times that of the inlet main pipe, ensuring highly efficient filtration.

      As for the external connection dimensions, this filter offers a variety of specifications to choose from, such as nominal diameters DN40, DN50, DN65, DN80, DN100, DN125, and DN150, meeting the connection requirements of different pipeline systems. The specific connection dimension data is detailed and precise, ensuring convenient and stable installation.


       In industrial fields such as metallurgy and petrochemicals, the efficient and stable conveying of pulverized coal is vital for maintaining production continuity. However, during the conveying process, pulverized coal inevitably mixes with various impurities, which act like stumbling blocks on a road. Once these impurities enter the conveying pipeline, they can cause blockages, posing challenges to production efficiency and safety. In this context, the pulverized coal filter, though seemingly insignificant, serves as a robust backbone for ensuring smooth production operations with its unique filtration capabilities.
