- 例えば、活性炭粒子又は残留炭酸塩粒子などの微細物質も含む石膏懸濁液(6)が湿式排煙スクラブのスクラバ(17)において生じ、前記石膏含有懸濁液(6)が少なくとも1つの液体サイクロン(1,1’)によって濃化され、前記濃化された石膏懸濁液(11)が前記液体サイクロン(1,1’)のアンダーフロー(8)を通じて排出される、排煙脱硫プラントの支援により石膏を回収するための方法において、
前記石膏懸濁液(6)に加え、水(5,5’,15,15’)が専用供給ラインを通じて前記液体サイクロン(1,1’)に供給され、それによって、結果的に、前記アンダーフロー(11,11’)中の懸濁液容量に対して微細物質が欠乏することを特徴とする方法。 - 請求項1に記載の方法において、前記液体サイクロン(1,1’)が円筒状インフロー領域(2,2’)と円錐状領域(3,3’)とを有することと、前記石膏懸濁液(6)の中間希釈用の希釈水(15,15’)として前記水(15,15’)が前記円錐状領域(3,3’)内又は前記アンダーフローノズル(8)の領域内に供給されることとを特徴とする方法。
- 請求項1に記載の方法において、前記液体サイクロン(1,1’)が1つの円錐状領域(3,3’)のみを有することと、前記石膏懸濁液(6)の中間希釈用の希釈水(15,15’)として前記水(15,15’)が前記円錐状領域(3,3’)内又は前記アンダーフローノズル(8)の領域内に供給されることとを特徴とする方法。
- 請求項1又は2に記載の方法において、前記液体サイクロン(1,1’)が円筒状インフロー領域(2,2’)と円錐状領域(3,3’)とを有することと、バリア水層(7)を形成するためのバリア水流(5,5’)として前記水(5,5’,15,15’)が前記液体サイクロン(1,1’)の前記インフロー領域(2,2’)内又は前記円錐状領域(3,3’)内に投入されることとを特徴とする方法。
- 請求項1又は3に記載の方法において、前記液体サイクロン(1,1’)が1つの円錐状領域(3,3’)のみを有することと、バリア水層(7)を形成するためのバリア水流(5,5’)として前記水(5,5’,15,15’)が前記液体サイクロン(1,1’)の入口領域内又は前記円錐状領域(3,3’)内に投入されることとを特徴とする方法。
- 請求項1乃至5の何れか1項に記載の方法において、前記バリア水流(7)と前記石膏懸濁液(6)とが、前記バリア水流(7)及び前記石膏懸濁液流(6)が実質的に安定になるまで前記液体サイクロン内においてラメラ(10)によって分離されることを特徴とする方法。
- 請求項1乃至6の何れか1項に記載の方法において、前記水(5,5’,15,15’)が前記液体サイクロン(1,1’)に対して接線方向に供給されることを特徴とする方法。
- 請求項1乃至7の何れか1項に記載の方法において、前記石膏含有懸濁液(6)が直列で連結された2つ以上の液体サイクロン(1,1’)によって濃化され、水(5,5’,15,15’)がいずれの場合においても専用供給ラインを通じて前記液体サイクロン(1,1’)に供給され、それによって、結果的に、前記各々のアンダーフロー(11,11’)中の前記懸濁液容量に対して微細物質が欠乏することを特徴とする方法。
