The present invention relates to water removal equipment for coal, which is used to reduce the water content of a coal. The water removal equipment for coal includes a microwave heating device. The microwave heating device includes a microwave cavity, a conveying element, and a plurality of microwave generating elements. The microwave generating elements generate microwaves and emit the same into the microwave cavity. The conveying element is arranged in the microwave cavity and conveys the coal from the inlet to the outlet of the microwave cavity. After the coal is microwave-heated by the microwave heating device, the water content of the coal is reduced from the range of 25% to 35% to the range of 10% to 20%, and the coal develops a plurality of cracks. The invention also relates to a water removal process for coal.
