Description
(実施例1)
内径950mm、高さ2160mmのスラリー室15に設置して図4と同様の商業規模で2種類の液体よりなる液滴スラリー製造装置を用いた。プレートは径509mmのものを使用した。ノズルを設置する場所に内径40mmのノズル穴を持っている。本実施例では37個のノズルを取り付ける構造となっている。ノズルはプレートとOリングでシールし、ボルトで4点締めして取り付ける構造となっている。ノズルは外形70mm(フランジ部幅15mmを含む)、径36mm内に孔を開けることができる。ノズルは内径0.17mmの孔を45個有し、隣同士の孔の距離は4mmとし、孔から噴出する液体の相互作用によって液滴の均一性が乱れないように配列した。このノズルをプレートに37個設置して使用した。全孔数は1665個である。37個のノズル配置は、図5に示すように、プレートの中心に1個、中心から半径78mmの同心円状に6個、半径156mm円状に12個、半径234mm円状に18個を配置した。ノズルは同心円上で均等距離に配置されている。
(実施例2)
プレートは23個のノズルを取り付ける構造とした以外は、実施例1と同様な商業規模の2種類の液体よりなる液滴スラリー製造装置を用いてスチレン液滴スラリーを製造した。ノズルは、内径0.10mmの孔を148個有し、隣同士の孔の距離は2mmとし、孔から噴出する液体の相互作用によって液滴の均一性が乱れないように配列した。このノズルをプレートに23個設置して使用した。全孔数は3404個である。23個のノズル配置は、図6に示すように、プレートの中心に1個、中心から半径78mmの同心円状に6個、半径210mm円状に16個を配置した。ノズルは同心円上で均等距離に配置されている。スラリー室に206リットル/時のPVA水溶液(PVA濃度は320ppmの希薄なもの)を供給しておき、液体導入口から257リットル/時のスチレンを供給し、加振機で1990Hzの振動を与えてO/W型の水溶液/スチレン液滴スラリーを製造した。必要な強さの加振を与えることにより、98%以上の割合で粒子径270μmの均一なスチレン液滴を得た。
(実施例3)
実施例1と同様な商業規模の2種類の液体よりなる液滴スラリー製造装置を用いた。使用したプレート、ノズルは実施例1と同様なものを用いた。プレートには37個のノズルを取り付けることができる。ノズルは内径0.10mmの孔を148個有し、隣同士の孔の距離は2mmとし、孔から噴出する液体の相互作用によって液滴の均一性が乱れないように配列した。このノズルをプレートに22個設置して使用した。残りの15個は閉止板を取り付けた。全孔数は3256個である。22個のノズル配置は、図7に示すように、プレートの中心に1個、中心から半径78mmの同心円状に6個、半径234mm円状に15個を取り付けた。半径156mm円状に12個、半径234mm円状に3個、計15個の閉止板を取り付けた。スラリー室に197リットル/時のPVA水溶液(PVA濃度は320ppmの希薄なもの)を供給しておき、液体導入口から246リットル/時のスチレンを供給し、加振機で1900Hzの振動を与えてO/W型の水溶液/スチレン液滴スラリーを製造した。必要な強さの加振を与えることにより、98%以上の割合で粒子径270μmの均一なスチレン液滴を得た。
(比較例1)
実施例1と同様な商業規模の2種類の液体よりなる液滴スラリー製造装置を用いた。本比較例ではノズルを使用せず、プレートに直接孔をあけて用いた。本比較例で使用したプレートは内径0.10mmの孔を3367個有する。隣同士の孔の間隔は実施例2と同じ2mmとした。スラリー室に204リットル/時のPVA水溶液(PVA濃度は320ppmの希薄なもの)を供給しておき、液体導入口から254リットル/時のスチレンを供給し、加振機で1990Hzの振動を与えてO/W型の水溶液/スチレン液滴スラリーを製造した。必要な強さの加振を与えたが、粒子径270μmの均一なスチレン液滴は65%の割合であった。
