- ドラムフィルタとして設計されたフィルタ装置(10)を連続的またはほぼ連続的に動作することにより、固形物(23)および懸濁液(32)を含む懸濁物(22)から該固形物(23)を抽出する方法において、
前記フィルタ装置(10)のフィルタドラム(14)は、濾過される前記懸濁物を受ける複数のチャンバに分けられ、一方の側すなわち高圧側(30)が他方の側すなわち低圧側(42)よりも高圧である濾過材(26)であって前記フィルタ装置(10)における複数の作業領域(I−V)を仕事方向(U)において連続的に通過する濾過材(26)を用い、
前記懸濁物(22)は、第1の作業領域(I)において前記濾過材(26)の前記高圧側(30)に供給されて濾過され、前記懸濁液(22)は、前記高圧側(30)と前記低圧側(42)との間の圧力差により前記濾過材(26)を貫流し、前記固形物(23)の少なくとも一部は、前記濾過材(26)に堆積し、
前記仕事方向(U)における前記第1の作業領域(I)の下流に配置される第2の作業領域(II)において、前記濾過材(26)に堆積した前記固形物(23)を前記濾過材(26)から分離することは、前記低圧側(42)から前記濾過材(26)への、ガスと混合された液体によるカウンターフラッシングによって補助され、
前記濾過材(26)から分離された前記固形物(23)は、前記第2の作業領域(II)におけるチャンバの濾過ケークに噴射される洗浄液(50)で再懸濁され、
こうして生成された新しい懸濁物(再懸濁物)(53)は、搬送システムを介して、前記仕事方向(U)において前記第2の作業領域(II)の下流に配置される第3の作業領域(III)におけるチャンバで再び濾過されることを特徴とする方法。 - 前記フィルタ装置(10)の外部に配設された洗浄器(44)であって、前記固形物(23)を収容すると共に、該固形物(23)に前記洗浄液(50)を供給し、該固形物(23)を再懸濁する洗浄器(44)によって、前記固形物(23)は、再懸濁されることを特徴とする請求項1に記載の方法。
- 前記洗浄器(44)は、前記再懸濁物の流れの障害となるように該流れの方向に対して順に続く複数の流れ障害物を有し該再懸濁物を混合する少なくとも一つの静的混合部(56)および/または前記再懸濁物を攪拌することにより該再懸濁物を混合する少なくとも一つの動的混合部(52)および/または前記再懸濁物を前記第3の作業領域(III)における前記チャンバに向けて送出する少なくとも一つのポンプ(54)および/または前記洗浄液(50)と前記固形物(23)との混合を促進し該固形物(23)の再懸濁を促進する少なくとも一つの混合容量部(46)を有する搬送部(56)を備えたことを特徴とする請求項2に記載の方法。
- 前記固形物(23;123)は、フィルタ装置(10;110)で再懸濁されることを特徴とする請求項1に記載の方法。
- 前記固形物(23;123)は、高い流速で送られる洗浄液(50;150)により再懸濁されることを特徴とする請求項1から4のいずれかに記載の方法。
- 前記第1の作業領域(I)において濾過され前記濾過材(26)に堆積した前記固形物は、濾過された後、該第1の作業領域(I)からの前記懸濁液(22)がまだ満ちている少なくとも一つの排出管(28)から、前記懸濁液(22)の一部または全てが排出されるまで処理ガスによりブローされることを特徴とする請求項1から5のいずれかに記載の方法。
- 前記フィルタ装置(10)は、ほぼ水平方向に延びる回転軸(A)の周りを前記仕事方向(U)に沿って回転する前記フィルタドラム(14)を備え、
前記フィルタドラム(14)が前記回転軸(A)の周りを前記仕事方向(U)に沿って回転する場合において、前記仕事方向(U)下流にある前記第1の作業領域(I)の端部(34)が、重力(g)と反対方向に上昇する前記フィルタ装置(10)の部分に位置するごとに、処理ガスがこの端部(34)近傍の前記濾過材(26)に堆積した前記固形物(23)に供給されることを特徴とする請求項1から6のいずれかに記載の方法。 - 前記固形物(123)は、少なくとも一回の更なる再懸濁物洗浄、すなわち前記濾過材(126)から除去され、洗浄液(1503)に再懸濁され、最後に再び濾過材(126)に送られて濾過され、
および/または、
少なくとも一度の貫流洗浄、すなわち前記濾過材(126)の前記高圧側(130)からその低圧側(142)へ流れる洗浄液(150)により洗浄されることを特徴とする請求項1から7のいずれかに記載の方法。
