Abstract
(EN)
Disclosed is a slurry drying plant (1) comprising a slurry extruder (3) including a slurry inlet (2) and conveying means (4) arranged to convey the slurry through the slurry extruder (3) and force the slurry out of a plurality of exit openings (5) of the slurry extruder (3) to form a plurality of slurry strings (7), wherein the slurry strings (7) are forced out into a drying chamber (8) in which the plurality of slurry strings (7) is dried. The slurry drying plant (1) further comprises slurry heating means (6) comprising flow means for passing superheated steam past the slurry strings (7) in the drying chamber (8), and inlet pressure detection means (9) for detecting a slurry inlet pressure at the slurry inlet (2). The slurry drying plant (1) also comprises control means (17) arranged to control the conveying speed of the conveying means (4) in response to the slurry inlet pressure. Furthermore, a method for drying slurry and use of a slurry drying plant (1) is disclosed.

L'invention concerne une installation de séchage de lisier (1) comprenant une extrudeuse de lisier(3) comprenant une entrée de lisier (2) et un moyen de transport (4) agencé pour transporter le lisier à travers l'extrudeuse de lisier (3) et forcer le lisier à sortir d'une pluralité d'ouvertures de sortie (5) de l'extrudeuse de lisier (3) pour former une pluralité de séries de de lisiers (7), les séries de lisiers (7) étant expulsées dans une chambre de séchage (8) dans laquelle la pluralité de séries de ls (7) est séchée. L'installation de séchage de lisier comprend en outre des moyens de chauffage de lisier (6) comprenant des moyens d'écoulement pour faire passer de la vapeur surchauffée au-delà des séries de lisiers(7) dans la chambre de séchage (8), et des moyens de détection de pression d'entrée (9) pour détecter une pression d'entrée de lisier au niveau de l'entrée de lisier(2). L'installation de séchage de bouillie (1) comprend également des moyens de commande (17) agencés pour commander la vitesse de transport du moyen de transport (4) en réponse à la pression d'entrée de suspension. En outre, l'invention concerne un procédé de séchage de boues et l'utilisation d'une installation de séchage de boues (1).
