Fluidizer

      The point-type fluidizer, as an indispensable key component in the blast furnace pulverized coal injection system, plays a pivotal role in the discharge process of powdered materials from the silo. As an aid-flow element, the point-type fluidizer is meticulously designed to optimize the overall performance of the coal injection system.

       During critical moments such as depressurization of the injection tank or pressure release by the safety valve, the point-type fluidizer ensures that the pulverized coal is finely filtered and safely retained within the tank, effectively preventing environmental pollution, reducing wear on pipelines and valves, and avoiding coal powder waste, thereby controlling production costs. Installed below the hopper, it fluidizes the powdered material by introducing air through the porous plate, significantly enhancing the fluidity of the pulverized coal, effectively preventing material bridging, and ensuring smooth material discharge.

       This fluidizer utilizes an innovative irreversible nozzle to construct the distribution plate, with a starting pressure as low as 0.05 MPa, greatly reducing pressure loss and effectively preventing powder-gas backflow. In the blast furnace pulverized coal injection system, the application of the point-type fluidizer successfully addresses the common issue of powder accumulation in multi-cone, multi-pipeline injection tanks. Additionally, the fluidizer can be flexibly connected in series or parallel to build a continuous coal injection system, which features simple processes, compact structure, and high safety and reliability, demonstrating outstanding performance.

      The core component of the point-type fluidizer—the fluidizing plate—is manufactured using advanced high-performance stainless steel sintered mesh material, ensuring high durability and efficiency of the equipment. These fluidizing plates are evenly distributed in the conical section of the injection tank (pulverized coal silo) and in the dead zones of the powder silo and powder conveying pipes, effectively preventing pulverized coal from adhering to the inner walls, agglomerating, or arching, further promoting the fluidization of the coal powder.

      It is particularly noteworthy that the point-type fluidizer not only delivers significant fluidization effects and stable performance but also features low air consumption, enabling maintenance-free operation. Its irreversible nozzle design ensures unidirectional airflow, effectively preventing powder-gas backflow, further enhancing the system's safety and reliability.

      In summary, the point-type fluidizer (also known as a conical fluidizer, fluidizing nozzle, or fluidizer nozzle) has become an indispensable accessory in the blast furnace pulverized coal injection system due to its excellent performance and broad application value. It not only optimizes the fluidization state of pulverized coal and improves material fluidity but also effectively prevents coal powder agglomeration, ensuring smooth material discharge, thereby supporting the efficient and stable operation of the blast furnace pulverized coal injection system.
