Title
(EN) METHOD FOR CONVEYING MATERIAL IN A PNEUMATIC MATERIAL CONVEYING SYSTEM, AND PNEUMATIC MATERIAL CONVEYING SYSTEM
(FR) PROCÉDÉ DE TRANSPORT DE MATÉRIAU DANS UN SYSTÈME DE TRANSPORT DE MATÉRIAU PNEUMATIQUE ET SYSTÈME DE TRANSPORT DE MATÉRIAU PNEUMATIQUE
Abstract
(EN)
A method for conveying material in a pneumatic material conveying system, such as a waste conveying system, which material conveying system comprises at least one material, specifically waste material, input point (60), a material conveying pipe (100) which is connectable into medium communication with a feed-in container of the input point (60), means for providing a pressure difference and/or transport air flow in the material conveying pipe at least for the time of transport of the material, which means for providing the pressure difference and/or transport air flow comprise at least one partial-vacuum generator (125A, 125B), and which material conveying system further comprises at least one separator device (90A, 90B), in which the transported material is separated from the transport air at an outlet end of the material conveying system. In the method the material is conveyed in a first stage from the input point (60) to a conveying pipe (100, 100A, 100B, 100C, 100D, 100E), into at least one container space (202, 202A, 202B) of an intermediate container (200, 200A, 200B) arranged between the input point (60) and the separator device (90A, 90B) by means of suction/pressure difference and/or transport air flow provided by the at least one partial vacuum generator (125A, 125B) in a first time period (t1), and that in a second stage of the method the material conveyed in the previous stage into the at least one container space (202, 202A, 202B) of the intermediate container (200, 200A, 200B) is conveyed by means of suction/pressure difference and/or transport air flow provided by the at least one partial -vacuum generator (125A, 125B) to the separator device (90A, 90B) in a second time period (t2). The invention also relates to a system.

L'invention concerne un procédé de transport de matériau dans un système de transport de matériau pneumatique, tel qu'un système de transport de déchets, ledit système de transport de matériau comprenant au moins un matériau, spécifiquement un matériau déchet, un point d'entrée (60), un tuyau de transport de matériau (100) qui peut être raccordé en communication fluidique avec un récipient d'alimentation du point d'entrée (60), des moyens pour fournir une différence de pression et/ou un flux d'air de transport dans le tuyau de transport de matériau au moins pendant la durée de transport du matériau, lesquels moyens pour fournir la différence de pression et/ou le flux d'air de transport comprenant au moins un générateur de vide partiel (125A, 125B), et lequel système de transport de matériau comprenant aussi au moins un dispositif de séparation (90A, 90B), dans lequel le matériau transporté est séparé de l'air de transport au niveau d'une extrémité de sortie du système de transport de matériau. Dans le procédé, le matériau est transporté dans un premier étage à partir du point d'entrée (60) jusqu'à un tuyau de transport (100, 100A, 100B, 100C, 100D, 100E), dans au moins un espace de récipient (202, 202A, 202B) d'un récipient intermédiaire (200, 200A, 200B) disposé entre le point d'entrée (60) et le dispositif de séparation (90A, 90B) au moyen d'une différence d'aspiration/de pression et/ou d'un flux d'air de transport fourni par le ou les générateurs de vide partiel (125A, 125B) dans un premier intervalle de temps (11), et dans un deuxième étage du procédé, le matériau transporté dans l'étage précédent dans le ou les espaces de récipient (202, 202A, 202B) du récipient intermédiaire (200, 200A, 200B) est transporté au moyen d'une différence d'aspiration/de pression et/ou d'un flux d'air de transport fourni par le ou les générateurs de vide partiel (125A, 125B) au dispositif de séparation (90A, 90B) dans un deuxième intervalle de temps (t2). L'invention concerne également un système.
