Title (EN) METHOD RELATING TO DISCONTINUOUS TREATMENT OF FIBRE MATERIAL
(FR) METHODE DE TRAITEMENT DISCONTINU D"UN MATERIAU FIBREUX
Abstract:
(EN) Method relating to discontinuous treatment of fibre material, where the material after a first treatment (10, 12) is transferred to subsequent treatment (26, 32). A substantial portion of the liquid constituent of the material is separated from the first treatment step in one or several intermediate steps preceding subsequent treatments and conveyed to a pressure accumulator (20) from which the heat energy contained in the liquid constituent is recovered and the liquid constituent subsequently subjected to a continuous treatment.
(FR) Methode de traitement discontinu d"un materiau fibreux selon laquelle le materiau, apres un premier traitement (10, 12), est transfere pour subir un traitement ulterieur (26, 32). Une partie substantielle du liquide constituant le materiau est separee apres la premiere phase de traitement au cours d"une ou de plusieurs phases intermediaires precedant le traitement ulterieur et transportee dans un accumulateur de pression (20) d"ou l"on recupere l"energie calorifique contenue dans le constituant liquide qui est ulterieurement soumis a un traitement continu.
