Description

A moisture-containing coal drying and dust removal integrated device

technical field

The invention relates to the technical field of water-containing coal drying treatment equipment, in particular to an integrated device for drying and dust removal of water-containing coal.

Background technique

Coal mines are areas where humans exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally chosen to excavate coal underground, which is an underground coal mine; when the distance between the coal seam and the surface is very close, it is generally chosen to directly strip the surface soil layer to excavate coal, which is an open-pit coal mine. Due to the weather, the coal mines collected after the rain contain a lot of moisture, which will cause the coal to be wet. On the one hand, it will lead to poor quality of coal, and on the other hand, it will increase the weight of transportation, which is very inconvenient. Now Some coal drying equipment does not dry uniformly enough. The drying efficiency of coal with severe humidity is very slow, the work efficiency is not high, and a large amount of dust will be generated during drying, which will aggravate the dust pollution of the outside world and affect the work. There is also a threat to the physical health of personnel.
