Zusammenfassung:The invention discloses a low-rank coal pulverization-continuous dry distillation system and process, and relates to the technical field of low-rank coal upgrading processing processes. According to the low-rank coal pulverization-continuous dry distillation system and process provided by the invention, the discharge of wastewater in the raw material coal processing process is completely eradicated, the problems of complicated subsequent wastewater treatment and high cost caused by incomplete dehydration of the raw material coal are avoided, the raw material coal resource is fully utilized due to preferential charring of the fine powder semi-coke, and the utilization rate of the raw material coal is improved. The controllable, rapid and uniform pyrolysis reaction is carried out in a normal-pressure system, so that the electric consumption of pneumatic conveying power is reduced, the equipment investment is reduced, no toxic and harmful gas is leaked in the whole process, the possibility that high-temperature
