Title (DE) VERFAHREN UND VORRICHTUNG ZUM WINDSICHTENDEN SEPARIEREN
(EN) AIR SEPARATION PROCESS AND DEVICE
(FR) PROCEDE ET DISPOSITIF D'AERO-SEPARATION
Abstract:
(DE) Es wird ein Verfahren zum windsichtenden Separieren von partikelförmige Verunreinigungen enthaltenden Holzfasern beschrieben, bei dem die Fasern zusammen mit einem Hilfsgasstrom (13) in einem senkrechten Fallstrom einem schräg gegen den senkrechten Fallstrom gerichteten und im wesentlichen wirbelfreien Trägergasstrom (18) zugegeben werden, wobei die partikelförmigen Verunreinigungen sich von den Fasern lösen und zur Abscheidung gelangen, während die gereinigten Holzfasern aus dem Hilfsgas- und Trägergasstrom abgetrennt werden.
(EN) In an air separation process for wood fibres which contain particles of impurities, the fibres are added together with a vertical, descending stream of auxiliary gas (13) to a substantially irrotational stream of carrier gas (18) slanted relative to the vertical, descending stream. The particles of impurities are loosened from the fibres and eliminated, whereas the cleaned wood fibres are separated from the streams of auxiliary and carrier gas.
(FR) Selon ce procédé d'aéro-séparation de fibres de bois qui contiennent des particules d'impuretés, on ajoute les fibres dans un courant descendant vertical de gaz auxiliaire (13) à un courant de gaz porteur (18) sensiblement exempt de tourbillons et incliné par rapport au courant descendant vertical. Les particules d'impuretés se détachent des fibres et sont éliminées, alors que les fibres de bois nettoyées sont séparées des courants de gaz auxiliaire et de gaz porteur.
