Claims (3)
- 水中に正多角形状に配置され、それぞれ連続的な上昇水流を発生させる複数の上昇水流発生手段であり、それぞれの上方水面に前記連続的な上昇水流で生起される同心円状に拡散する連続的な拡散流を発生させ、隣り合う拡散流同士の相互干渉により前記正多角形状の中心部に水面から水底に向かう連続的な下降水流を誘起させて、前記連続的な上昇水流と前記連続的な下降水流とによる上下循環流を形成する複数の上昇水流発生手段と、
前記上下循環流の下降水流に向かって被拡散物を放出する被拡散物供給手段と
を含む拡散装置。 - 前記複数の上昇水流発生手段は、開口部が上向きに配置された筒体と、前記筒体内に開口部が前記筒体の中心軸に向かって斜め上向きに配置された複数のノズルであり、その中途部の内側に圧縮空気が噴出される複数のノズルとを備えたものである請求項1記載の拡散装置。
- 水中に正多角形状に配置された複数の上昇水流発生手段によりそれぞれ連続的な上昇水流を発生させて、前記複数の上昇水流発生手段のそれぞれの上方水面に前記連続的な上昇水流により生起される同心円状に拡散する連続的な拡散流を発生させ、隣り合う拡散流同士の相互干渉により前記正多角形状の中心部に水面から水底に向かう連続的な下降水流を誘起させて、前記連続的な上昇水流と前記連続的な下降水流とによる上下循環流を形成すること、
前記上下循環流の下降水流に向かって被拡散物を放出すること
を含む拡散方法。
