【考案の詳細な説明】
本考案は、粉粒体流動床炉内における流動状態
を視認するための粉粒体流動加熱実験装置に関す
る。[Detailed description of the invention] The present invention relates to a powder/granular fluidization heating experimental device for visually observing the fluidization state within a powder/granular fluidized bed furnace.
粉粒体を流動状態に保持した流動層は熱交換機
能の外、重質油を熱分解して軽質油ならびに分解
ガスを製造すると共に還元鉄を製造する方法にお
いて熱分解炉,還元炉として重要な役割を有して
いる。 In addition to its heat exchange function, the fluidized bed that holds powder and granules in a fluidized state is important as a pyrolysis furnace and reduction furnace in the process of pyrolyzing heavy oil to produce light oil and cracked gas, as well as producing reduced iron. It has a role to play.
殊に、重質油の熱分解炉,還元炉として使用さ
れる場合には600〜700℃あるいはそれ以上の高温
が必要であり、粉粒体の高温化が要求される。 In particular, when used as a pyrolysis furnace or a reduction furnace for heavy oil, a high temperature of 600 to 700°C or higher is required, and the powder and granules are required to be heated to a high temperature.
ところが、流動層においては一般に使用される

ス流速が制限され、生産性又は還元率に影響し、
又、高温化することにより反応速度が上り、生産
性が向上するとしても余り高温になると、粒子相
互が固着し合い、粒子の運動状態は不良となり、
これをそのまま続行すると、ついには粒子層が連
結体を形成し、シンタリング現象を惹起する。 However, in a fluidized bed, there are restrictions on the particle size of the powder or granules that are generally used, and if they are too fine, the gas flow rate will be restricted, which will affect productivity or reduction rate.
In addition, even though increasing the temperature increases the reaction rate and improves productivity, if the temperature is too high, particles will stick to each other and the state of particle movement will be poor.
If this continues as it is, the particle layer will eventually form a connected body, causing a sintering phenomenon.
しかしながら、流動層はその有用性が認識さ

石粒子の流動層還元時の粉粒体の流動状態に関し
ては殆んど未知の状態にある。 However, although the usefulness of the fluidized bed is recognized and it is widely used, the sintering phenomenon described above and the flow state of powder and granular materials in the fluidized bed have not been fully elucidated to date. In particular, the fluidity state in the pyrolysis furnace during the production of reduced iron, which requires high-temperature operations of over 800°C, and the granules during fluidized bed reduction of carbon-adhered iron ore particles, which are expected to be put into practical use more and more in the future. Almost all of the flow conditions are unknown.
これは流動層内の状態を探知する必要がなかつ
たことにもよるが、実験装置として高温下にある
粉粒体の流動状態を検知し得る適切な装置がなか
つたことによるものである。 This is partly due to the fact that there was no need to detect the state within the fluidized bed, but also because there was no suitable experimental equipment capable of detecting the fluidized state of powder particles under high temperature.
しかして、前記還元鉄製造時に利用する流動層
では軽質油留分、ないし分解ガスと還元鉄を高い
効率で製造するためには流動層の役割は大きく、

It is an important research topic to understand the flow state of powder and granular materials in a fluidized bed at high temperatures.

結合せしめた構成を特徴とするものである。 In view of the above-mentioned circumstances, the present invention addresses the above-mentioned problem by improving the fluidization state of powder and granules in a fluidized bed, especially at temperatures between 600°C and 800°C.
Furthermore, it was devised to understand the flow state at higher temperatures, and the inner tube was a transparent quartz concentric double tube with a heating element interposed in the middle of a Pyrex tube with a thin gold film deposited on the inner wall. Based on the use of multiple transparent tubes, this is used as a vertical cylindrical furnace with a perforated plate placed at the bottom to form a vertical fluidized bed cylindrical furnace, and a hopper-shaped chute is connected to the upper end. , and is characterized by a configuration in which desired mechanical means such as a gas supply means, a gas discharge means, and a powder collection means are attached and connected.

得る。 In this way, when powder and granules are loaded into a cylindrical furnace and gas is supplied from below, the gas passes through the furnace and the flow rate decreases at the upper hopper-like chute, making it easy to discharge the gas. The flow state of the powder and granules was visually observed through the transparent wall, and the state of the sample was checked as appropriate.
By moving the rod member 22 up and down, the lid member 23 is opened at the upper end opening of the collection tube 20, and the sample can be collected for use in experiments.
