The blower is in communication with the surge tank. One end of the two pipelines connected in parallel communicates with the surge tank, and the other end thereof communicates with a fluidized bed. One of the two pipelines is formed by sequentially connecting a first valve, a first flow meter, an air heater and an electric butterfly valve in series, and the other one of the pipelines is formed by connecting a second valve and a second flow meter in series. The moisture detection sensor is arranged within the fluidized bed, and the control device is respectively connected to the blower, the first valve, the first flow meter, the air heater, the second valve, the second flow meter and the moisture detection sensor. Brown coal particles in the fluidized bed are dried first and then separated, making it possible to complete the dewatering, deashing, upgrading and separating of the brown coal particles in one process flow, increasing work efficiency and simplifying the process flow. (FR) L'invention concerne un systeme accouple et un procede permettant de separer et secher de fines particules de charbon humide, le systeme accouple comprenant une soufflante, un reservoir d'equilibre, un capteur de detection d'humidite, un dispositif de commande et deux pipelines. La soufflante est en communication avec le reservoir d'equilibre. Une extremite des deux pipelines raccordee en parallble communique avec le reservoir d'equilibre, et l'autre extremite de ceux-ci communique avec un lit fluidise. L'un des deux pipelines est former en raccordant sequentiellement une premiere soupape, un premier debitmetre, un rechauffeur d'air et une vanne papillon electrique en serie, et l'autre des pipelines est former en raccordant une seconde vanne a un second debitmetre en serie. Le capteur de detection d'humidite est dispose a l'interieur du lit fluidise, et le dispositif de commande est respectivement raccorde a la soufflante, l la premiere vanne, au premier debitmetre, au rechauffeur d'air, l la seconde vanne, au second debitmetre et au capteur de detection d'humidite. Des particules de lignite dans le lit fluidise sont d'abord sechees puis separees, ce qui permet de realiser la deshydratation, le decendrage, la valorisation et la separation des particules de lignite dans un seul flux de traitement, d'augmenter l'efficacite de travail et de simplifier le flux de traitement.
