Description
本例では、従来技術(Aは図1に対応するが、浄化部の高さは図6における高さと同じである)と本発明(Bは図6に対応する)とを比較する。どちらの場合も、基本的な反応炉および作業条件は同じである。2種類の異なる粉末材料を両者に使用する。本発明による反応炉(B)では、円形調整シムの直径はφ=85mmである。これらの異なる4つの例を以下の表に示す。ここで、
A1は、密度ρs=8900kg/m3の銅粉末を工程の初期段階で反応炉に使用した場合の従来技術の反応炉であり、
A2は、浸透反応が起きることで、密度ρs=4450kg/m3の混合物粉末が形成される場合の従来技術の反応炉であり、
B1は、密度ρs=8900kg/m3の銅粉末を工程の初期段階で反応炉に使用した場合の本発明による反応炉であり、
B2は、浸透反応が起きることで、密度ρs=4450kg/m3の混合物粉末が形成される場合の本発明による反応炉である。
すなわち、約1/10になる
− 混合物: 本発明/従来技術=B2/A2=16/68=0.24
すなわち、約1/4になる
本例が示すとおり、本発明による反応炉構造を用いると、反応炉から溶液と共に除去される粉末の量は、ある実施例においては10分の1になり、より困難なケースでは4分の1になる。
図4による装置では、銅粉末をベースとする流動床を使用して、銀を塩化第一銅溶液から除去する。流動床が形成された反応炉の反応部の直径は1.5m、高さは3.5mである。反応部の下層部には、凝集体を粉砕するための4枚羽根のミキサーが備えてあり、このミキサーはピッチ羽根タイプで、直径が0.6mである。
