Description
以下では、図面を用いて本発明を詳細に説明する。図1〜4は第1実施形態にかかる気固分離器の一形態を示すもので、図1は一部破断斜視図、図2は図1の気固分離器の縦断面図、図3は気固分離機をIII−III面で切断した横断面図、図4は案内羽根付近の流れを示す斜視図である。
内筒10は、鉛直方向に延びる有底円筒状で上端が開口して導入口1を形成しており、この導入口1からは粒子と気体の混合物が導入されることになる。下端は底板11によって封止されている。
また、実用的な長孔4の鉛直方向長さLは、後述する上部外筒2aの高さLa及び下部外筒2bの高さLbを用いて次式で表される。
案内羽根5の最大高さ=外筒2の長さ
好ましくは長孔4の長さL以上かつ0. 8×外筒2の長さである。
外筒2はこの内筒10を外方から覆って同軸状に位置する筒状体である。外筒2は、上から順に、気体案内筒2c、上部外筒2a、下部外筒2b、円錐筒2d、及び、粒子抜出管2eから構成されている。特に、上部外筒2a及び下部外筒2bが、内筒10における複数の長孔4が形成された部分10aを取り囲むように形成されている。すなわち、上部外筒2aは、主として、各長孔4が形成された部分10aの上部を取り囲むように形成され、下部外筒2bは、主として、各長孔4が形成された部分10aの下部を取り囲むように配置されている。下部外筒2bは、内筒10の底板11よりさらに下に伸びていることが好ましい。
次に、第2実施形態について図8を参照して説明する。重質油を原料油としてガソリンを製造する流動接触触媒装置に本気固分離器を再生する際には、粒子抜出口3からの排出される触媒は、粒子群の隙間にガスを含んでいると共に、粒子には重質油が吸着されている。したがって、粒子抜出口3からの触媒は、通常、図示しないストリッピング装置に供給され、スチーム等の不活性ガスによりこれらが除去される。
以下の条件の、図1〜図4のような形態の気固分離器を用いて、平均粒径60μm、粒子嵩密度0.7g/cm3の固体粒子を含む温度20℃の空気の分離実験を行った。気固分離器のスケール及び条件は、図9に示す。長孔(案内羽根)の数は12とした。触媒補修率(単位:%)=(固体抜き出し口から抜き出された固体の重量)/(分離器に供給された触媒の重量)とした。
下部外筒2bの内直径D1を、上部外筒2aの内直径D2と同じにした以外は実施例1とした。
案内羽根の半径方向突出長さPを図10のように代える以外は、実施例1と同様にした。
ポケット高さを代える以外は実施例1と同様にした。
