Description
1次渦流に加えて、2次渦流が、取付け管の背方と面羽根の自由縁部のところとに発生する。これらの2次渦流は、明らかに局所的な混合に寄与はするが、圧力損失を生じさせ、かつ望ましくない振動を発生させる。2次渦流の発生が少なくとも部分的に防止されれば、好都合だろう。
この静止ミキサは、通過流方向に渦流を発生させるための少なくとも1対の羽根を含んでいる。羽根の前縁は、通過流に対し直角であり、流路の短尺側と平行である。以下、この短尺側を簡単に高さと呼ぶことにする。前縁部から下流方向に続く、流れの当る面は、凹状に湾曲し、反対方向に向いている。各羽根は、空気力学的に設計された体部として形成され、該体部は、端壁と、凸状の側壁と、凹状の側壁とを含んでいる。端壁は、凸状又は前縁の形状を有している。側壁に対し直角の羽根の断面は、特に、航空機の翼の断面に似た形状を有している。
従属請求項2から請求項10には、本発明によるミキサの複数好適実施例が記載されている。
以下で、図面を参照して本発明を説明する。
羽根表面に沿って流れ区域に悪影響を与えるような、又は塵埃が付着してミキサ1の動作を妨害するような外側取付式の補強構造物、例えばリブ等は、不要である。
開口42は添加物用の給送経路に接続できるが、添加物が羽根区域の中空体部へ直接に送られようにすることも可能である。
特に好ましい実施例では、DE−A−195 39 923により公知のように、羽根対2の側壁21,22が、管に対し直角のガセット板(図示せず)によって結合される。ガセット板が直線状の辺を有する3角形の場合、縁部が凹状側壁22を超えて突出する。このガセット板の突出縁部により混合効率が改善され、しかも圧力損失が増すことがない。
本発明によるミキサの使用が特に好ましいのは、流路10の高さ(短尺側)が0.5mを超える場合、好ましくは1mを超える場合である。1段に配置された混合部材2(羽根対)は、流路10の高さを超えて延びるのが好ましい。その場合、混合部材2の数は、結果として、流路の幅/高さの商に事実上等しい。この数の通常の値は、2個‐8個の範囲である。混合部材2の数に応じて−多少の差はあれ効率的な−多くの異なる構成が得られることで、例えば、あらゆる混合部材2が交互の方向に回転するか又は等方向に回転する結果が得られる。したがって、或る状況で初期条件として与えられた温度又は濃度の不一様な分布を結果する対象があれば、それに即して、混合部材2の構成を最適化することが可能である。羽根対2は、また1「段」ではなく、2「段」以上に配置することもできる。これらの「段」は、通例、互いに壁部で隔てられてはいない。
