Fluidization Artifact
In the field of pulverized coal conveying, the pulverized coal fluidized conveyor plays a pivotal role. This "fluidization artifact" is a key device for pulverized coal transportation, just like the silent yet extremely crucial combustion-supporting wind, hidden at the lower part of the injection tank, quietly exerting its effect.
I. Its Purpose and Characteristics
This artifact is the wing of pulverized coal transportation. It is mainly made of liquid special diffusion metal mesh plate, and is equipped with a gas equalizer inside, ensuring uniform and complete airflow distribution in the fluidized bed. As a result, the pulverized coal can be better fluidized, making its transportation work smooth and efficient.
II. Revelation of Its Performance Parameters
It is like a flexible warrior, capable of handling challenges from various media. Whether it is air or nitrogen accompanying the pulverized coal, it can easily cope. Its working temperature ranges from 0 to 100℃, and the design pressure can be freely adjusted between 0.6 and 1.6MPa.
III. Various Forms to Adapt to Different Processes
According to the process requirements of pulverized coal conveying, this artifact is divided into two forms: "upper discharge" and "lower discharge".
1. SLH-type Upper Discharge Fluidization Device
This device is a combination of an integrated type and a split bed type, designed specifically for the upper discharge of the coal injection tank. Regardless of the flange standard and specification, it can be customized as needed to flexibly meet requirements.
2. XLH-type Lower Discharge Fluidization Device
This is a fluidization device designed for the discharge at the lower part of the pulverized coal bin. It has a wide range of production specifications, with the coal inlet ranging from DN1000 to DN400, and the coal outlet extending from DN600 to DN1500. It can meet any requirements.
IV. Fluidization Injection Technology for Metallurgical Blast Furnaces
In the pulverized coal injection of metallurgical blast furnaces, another fluidization injection device is particularly notable. It adopts 1Cr18Ni9Ti stainless steel plate, on which the long strip-shaped slits are arranged in a cross shape, perpendicular to the center line. The slit gap is only 0.5mm, the length is about 20mm, and the spacing is 10mm. After being chamfered at 1×45°, compressed air can be concentrated in the center of the fluidization injection device, enhancing the suspended fluidization effect of the pulverized coal, making the pulverized coal flow more smoothly and ensuring the stability of pulverized coal injection. This innovative design has greatly improved the working efficiency and effect of the fluidization injection device.
Such fluidization artifacts are truly powerful tools for industrial transportation, being both efficient and stable, and can be regarded as treasures of the industry.
