Title:
COUPLED SYSTEM AND METHOD FOR SEPARATING AND DRYING MOIST FINE COAL PARTICLES
Document Type and Number:
WIPO Patent Application WO/2018/133220
Kind Code:
A1
Abstract:
Disclosed is a coupled system and method for separating and drying moist fine coal particles, the coupled system comprising a blower, a surge tank, a moisture detection sensor, a control device and two pipelines. 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.
