Abstract

L’invention concerne un type de dispositif d’élimination des cendres à sac composite comprenant un boîtier, des sacs d’élimination des cendres, une trémie à cendres inférieure, etc. Une trémie à cendres supérieure et un conduit à cendres sont agencés dans le boîtier pour le séparer en un compartiment supérieur et un compartiment inférieur. Les compartiments supérieur et inférieur disposent chacun de sacs d’élimination des cendres, d’une entrée de gaz à cendres et d’une sortie de gaz filtré. Une cloison supérieure et une cloison inférieure sont agencées pour séparer respectivement les compartiments supérieur et inférieur en un collecteur de gaz supérieur et un collecteur de gaz inférieur. Dans les compartiments supérieur et inférieur, des systèmes de soufflage à impulsion inversée sont disposés pour ventiler de manière inverse le sac afin d’éliminer les cendres. Le conduit d’amenée de gaz reliant l’entrée de gaz à cendres du compartiment supérieur à celle du compartiment inférieur et le conduit d’évacuation de gaz reliant la sortie de gaz filtré du compartiment supérieur à celle du compartiment inférieur sont disposés à l’intérieur ou à l’extérieur du boîtier. L’invention permet d’accroître la surface de filtration utile du boîtier, d’où une meilleure efficacité de l’élimination des cendres, et de réduire le nombre de compartiments et l’encombrement du boîtier.
