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。
実用に適する長孔4の水平方向の幅Wは、上述の条件を満たす範囲で、内筒10の円周長さL1を用いて例えば次式で表すことができる。
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、円筒状の中央外筒2a、円錐筒2d、及び、粒子抜出管2eから構成されている。特に、中央外筒2a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。中央外筒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dp=60μmの粒子密度ρp=1.2g/cm3の固体粒子を含む粘度μ=0.000023Pa・sの空気の分離の実験を行った。気固分離器のスケール及び条件は、図7のようにした。すなわち、長孔の各面積は維持しつつ、長孔の長さを変えて、それぞれ、St=0.45,0.32,0.65とした。触媒捕集率(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。
さらに、長孔の長さを代えて、ストークス数St=0.21とする以外は実施例1と同様にした。

前記長孔夫々の一方の長辺縁部には外方に突出すると共に前記各長孔を覆うように周方向に傾斜された案内羽根が設けられた気固分離器の設計方法であって、
前記内筒の開口から下向きに供給する気体及び固体粒子の混合物を断面平均線速度をU[m/s]、前記固体粒子の粒子密度をρp[kg/m3]、前記固体粒子の平均粒径をdp[m]、前記気体の粘度をμ[Pa・s]としたときに、前記長孔の長さLを、
