Description
流動床・噴流床方式の造粒器を用いて原料水溶液から顆粒物を製造する造粒法に用いられる原料水溶液噴射用ノズルであって、下記特徴を有するマルチノズル。
(1) 上に凸の三角錐状の本体に、上に凸の三角錐状のノズル端が等間隔で且つ放射状に2〜6個設置され、
(2) 個々のノズル端の噴射角度が15〜45°の範囲内にあり、且つマルチノズル全体の噴射角度が30〜60°の範囲内にあり、
(3) 一つのマルチノズルの処理量が0.6〜2.0t/hrであり、且つ個々のノズル端の処理量が0.1〜0.4t/hrである。
造粒物を流動している流動床に、空気を噴出する空気供給管とその中央部に設けられた原料水溶液噴射用ノズルと、流動床に流動用空気を供給する多孔板からなる造粒器を用いて、上記原料水溶液噴射用ノズルから原料水溶液を造粒部に噴射して造粒する方法において、原料水溶液噴射用ノズルとして下記特徴を有するマルチノズルを用いることを特徴とする顆粒製品の製造方法である。
(1) 上に凸の三角錐状の本体に、上に凸の三角錐状のノズル端が等間隔で且つ放射状に2〜6個設置され、
(2) 個々のノズル端の噴射角度が15〜45°の範囲内にあり、且つマルチノズル全体の噴射角度が30〜60°の範囲内にあり、
(3) 一つのマルチノズルの処理量が0.6〜2.0t/hrであり、且つ個々のノズル端の処理量が0.1〜0.4t/hrである。
参考例1
図3に示す流動床・噴流床造粒器を使い、41.7 トン/時の顆粒尿素を生産する。そのフローを図4に示す。
参考例2
そこで、上記運転状態で流動床用空気を加熱して徐々に流動床温度を上げ、110℃を越したところで製品中の水分が0.3 wt.%を下回るようになった。更に流動床用空気を55℃まで加熱して流動床温度を115℃まで上げた。その結果、得られた顆粒尿素の水分は0.2-0.25 wt.%に低下して、直径3mmサイズ顆粒尿素の荷重強度も3.5-4kgに上昇した。
実施例1
参考例1において、ノズルとして図1に示す本発明のマルチノズルを用いた以外は参考例1と同様にして顆粒尿素を製造した。
実施例2
参考例2において、ノズルとして図1に示す本発明のマルチノズルを用いた以外は参考例2と同様にして顆粒尿素を製造した。
