DEVICE AND METHOD FOR PNEUMATICALLY CONVEYING BULK MATERIALS IN A DENSE FLOW METHOD

The invention relates to device for pneumatically conveying a free-flowing bulk material in a dense flow method, containing a cross-sectionally closed conveying line (3) with a conveying channel (2), a compressed gas auxiliary line (4) with a compressed gas channel (18), and means (5) which permit the passage of compressed gas and which serve to supply the conveying channel (2) with the compressed gas from compressed gas channel (18). The invention is characterized in that a fluidizing device is assigned to the conveying line (3), and the fluidizing gas and which serve to supply a fluidizing gas from the fluidizing gas channel (8) and into the conveying channel (2). Linvention porte sur un dispositif de transport pneumatique de produits en vrac circulant librement lors dun procédé à flux dense, comportant un conduit de transport fermé à section transversale (3) ayant un canal de transport (2), un conduit auxiliaire de gaz comprimé (4) ayant un canal de gaz comprimé (18) et des mécanismes (5) qui permettent le passage du gaz comprimé et qui servent à approvisionner le canal de transport (2) en gaz comprimé provenant du canal de gaz comprimé (18). Linvention est caractérisée par le fait quun dispositif de fluidisation est associé au conduit de transport (3) et au gaz fluidisant et sert à approvisionner un gaz fluidisant à partir du canal de gaz fluidisant (8) et dans le canal de transport (2).
