The point-type fluidizer, also known as a cone fluidizer, fluidizing nozzle, or jet, is a critical flow-aid component in the discharge process of powdered materials from storage bins. It is not only an important accessory in blast furnace pulverized coal injection systems but also plays an irreplaceable role in the fluidization of materials. The fluidizer is ingeniously installed at multiple points in the conical section of the injection tank (pulverized coal bin) and in dead zones of the powder bin and conveying pipes. This well-designed layout not only effectively prevents coal powder from caking but also ensures smooth fluidization of the coal powder.

       In the operation of blast furnace pulverized coal injection systems, the point-type fluidizer acts like a precise regulator. Air is introduced through the porous plate of the fluidizer, accurately fluidizing the powdered material, significantly enhancing its flowability, and effectively preventing material stagnation caused by bridging. This ensures smooth material discharge. This process not only guarantees the smooth operation of the coal injection system but also ensures that the fluidization state of the coal powder is optimal.
      Under dual considerations of technological innovation and material selection, the fluidizing plate used in the point-type fluidizer is made of high-tech, high-performance sintered stainless steel wire mesh. This material choice not only enhances the durability of the fluidizer but also ensures stable performance even in harsh working environments. The layout design of the fluidizer is equally ingenious, with uniform installation in the conical section of the injection tank and dead zones of the powder bin and conveying pipes. This design fundamentally eliminates the possibility of coal powder adhering to the inner wall of the injection tank, caking, or arching.

       It is worth mentioning that the point-type fluidizer boasts many notable product features. Its fluidization effect is excellent, performance is stable, air consumption is low, and it requires no maintenance. This is thanks to the distribution plate composed of irreversible nozzles, which results in a pressure loss as low as 0.05 MPa upon startup, effectively preventing powder and gas backflow. Additionally, after installing the fluidizer in the injection tank, the issue of powder accumulation in multi-cone and multi-pipe injection tank configurations is fundamentally resolved.
       Moreover, the point-type fluidizer demonstrates significant advantages in system integration. It can be flexibly configured to form continuous coal injection systems for series or parallel bottom discharge. Such systems are not only simple in process and compact in structure but, more importantly, safe and reliable. Its application not only improves the operational efficiency of the coal injection system but also plays a vital role in ensuring production safety and environmental protection.

      Furthermore, the installation and application of the point-type fluidizer reflect a deep commitment to environmental protection. During pressure release from the injection tank or safety valve discharge, the coal powder is finely filtered by the fluidizer and retained in the tank. This effectively prevents environmental pollution from coal powder, reduces wear on pipelines and valves, and avoids waste of coal powder, thereby lowering production costs and contributing significantly to the sustainable development of enterprises.
       In summary, with its unique design, excellent performance, and wide range of applications, the point-type fluidizer has become an indispensable key component in blast furnace pulverized coal injection systems. Its presence not only ensures the smooth progress of the production process but also provides solid support for the long-term development of enterprises.
