Description
即ち、別の工程段階から得られ、同時に化学物質の供給に使用することができるすべての液体によって、清水が節約され、例えば製紙工場の清水の消費が低減される。しかし、上述の様々な混合装置の応用例はすべて、ダクト内を流れる加圧された液体への化学物質の添加を扱ってきた。一方、開いた容器内の又は開いたダクト内を流れる液体に化学物質を添加することは、問題であると長い間考えられてきた。この種の問題点の例は、抄紙機のワイヤ・ピット、ワイヤ・スパウト、或いは、製紙業又はその他のいずれかで使用される2次液体ダクト又は濾過ダクトであり、例えば、消泡剤、又は上述の液体の処理に使用される化学物質は、化学物質を、薄いパイプから、ワイヤ・ピット、ダクト、又はチャネル内の液面へと緩やかに流すことを可能にすることによってそれらすべてに最も一般的に投与され、混合は流れの乱流のみに依存する。この種の開空間又はチャネル内の流速は、ほとんどの場合比較的低く、流れの乱流は、非常に弱いので、混合に時間がかかり、長い流れ距離が必要とされる。さらに、一方では流速が非常に低いため、もう一方では流れ体積が大きいことが多いため、いくつかの閉じたダクト流内で乱流を生み出すことを意図して使用される流れ障壁の使用が、かなり無益であることが留意されるべきである。
