Abstract

L'objectif de l'invention est de produire, à peu de frais d'appareillage et d'énergie, des granules plus grosses à humidité résiduelle réduite, par séchage de liquide épais collants, pouvant être faiblement déshydraté. A cet effet, une centrifugeuse est intégrée dans un logement de séchoir et située dans un dispositif combiné de déshydratation et de séchage, de sorte qu'au moins une partie d'évacuation de déchets de la centrifugeuse est placée directement dans le logement de séchoir et que les particules humides du brouillard de fines gouttelettes de matières projeté de la centrifugeuse atteignent directement, de manière bien répartie dans l'espace, les particules sèches du lit fluidisé à envelopper et à faire circuler, après de nombreux retournements. Le temps d'arrêt momentané dans la zone de pulvérisation des particules, destinées à être grossies par granulation de constitution et à être séchées simultanément, est variable en fonction de la vitesse du gaz chaud. Le flux gazeux chaud est influencé de manière ciblée par des éléments d'impact et des conducteurs, de façon à répartir la matière et le gaz de manière uniforme, ce qui permet d'éviter les zones mortes et de favoriser un contact intensif entre le gaz chaud et les particules de matière qui grossissent continuellement. Selon l'invention, les particules de liquide épais humides, prédeshydratées mécaniquement dans la centrifugeuse, puis dispersées finement, sont réparties uniformément dans le gaz de séchage contenant de la matière, et elles ne sont pas mises en contact prématurément avec les parois du séchoir. Les particules fines, séchées sont grossies par granulation de constitution et le séchoir comprenant une centrifugeuse est protégé de l'encrassement par des produits collants sans reconversion ou par prétraitement des boues.
