Beschreibung
Zusammenfassung:	The embodiment of the utility model provides a high-temperature extraction system for low-rank coal, which comprises an extraction tank for extracting the low-rank coal and a solvent in the extraction tank; the settling tank is connected with the extraction tank, so that the extraction liquid and the raffinate in the extraction tank can enter the settling tank together and are settled and separated under the action of weight, the raffinate is settled to the bottom of the settling tank, and the extraction liquid is positioned above the raffinate; the distillation retort is connected with the settling tank, so that the extract liquor separated from the settling tank enters the distillation retort to be distilled; the receiving tank is connected with the distillation tank, so that the solvent steam in the distillation tank enters the receiving tank to be condensed and recycled. The high-temperature extraction system for the low-rank coal disclosed by the embodiment of the utility model is high in extraction rate
