Fluidizer

Lanhao Environmental Protection Point-Type Fluidizer Product Overview
● The point-type fluidizer utilizes a fluidization plate made from high-tech, high-performance sintered stainless steel mesh, offering excellent performance.
● This fluidization plate is uniformly installed in the conical section of the injection tank (pulverized coal bin) and in dead zones of the powder bin and powder conveying pipes, effectively preventing pulverized coal from adhering, caking, and arching on the inner walls of the injection tank, enabling smooth fluidization of the coal powder.
● The point-type fluidizer demonstrates outstanding fluidization effects, stable performance, low air consumption, and is almost maintenance-free. Its distribution plate, composed of non-return nozzles, has minimal pressure loss (starting at just 0.05 MPa) and effectively prevents reverse flow of powder and gas.
● Installed on the injection tank, the fluidizer eliminates the issue of powder accumulation in the conical sections of multi-cone, multi-pipeline injection tank configurations. It can be flexibly arranged to form continuous coal injection systems for series or parallel bottom discharge, with the entire system featuring simple processes, compact structure, and high safety and reliability.

The point-type fluidizer (including conical fluidizers, fluidizing nozzles, and fluidizer nozzles) is a critical flow-assisting component in the process of discharging powdered materials from storage bins. In blast furnace coal injection systems, it plays a vital role. This equipment is installed at multiple points in the conical sections of the injection tank (pulverized coal bin), the powder bin, and dead zones of the powder conveying pipes. Its function is to prevent coal powder from caking, enabling it to be conveyed in a fluidized state.
Specifically, by introducing air through the porous plate, the powdered material is fluidized, enhancing its flowability and effectively preventing bridging, allowing the material to be discharged smoothly. Installing fluidizers at the lower part of the hopper not only ensures that pulverized coal is effectively retained in the tank during pressure relief or safety valve operation but also prevents environmental pollution, pipeline and valve wear, thereby avoiding waste of coal powder and increased costs.

      Additionally, the arrangement of fluidizers is flexible and diverse, allowing for multi-point installation based on actual needs to achieve multi-point fluidization of the material. At the same time, there is a wide variety of fluidizers, including bin fluidizers, disc-type fluidizers, and plate-type fluidizers, with bin fluidizers being the primary type. These different types and configurations of fluidizers collectively form an indispensable part of blast furnace coal injection systems.

      Technically, the distribution plate composed of non-return nozzles used in this fluidizer has minimal pressure loss, can start at low pressure, and effectively prevents reverse flow of powder and gas. Furthermore, the fluidizers installed on the injection tank address the common issue of powder accumulation in the conical sections of multi-cone, multi-pipeline injection tank configurations. By appropriately configuring the fluidizers, continuous coal injection systems for series or parallel bottom discharge can be formed, making the entire coal injection system's process simpler, structure more compact, and highly safe and reliable.
      In summary, as a key component of blast furnace coal injection systems, the point-type fluidizer not only assists in the flow of powdered materials during discharge but also provides essential support for the stable operation of the coal injection system and the efficient utilization of pulverized coal.
