Description

technical field [0001] The invention relates to a coal processing application device, in particular to a coal quality upgrading device for microwave low-temperature dehydration and desulfurization. Background technique [0002] High moisture content of coal will lead to low calorific value and high transportation cost. For example, the moisture content of coal slime reaches more than 25%, and the calorific value is 3000-4000 kcal. The moisture content of lignite is as high as about 33%, and the calorific value is between 3700-4300 kcal. . Therefore, the dehydration and drying of coal has positive significance for improving coal quality and improving transportation efficiency. However, the dehydration methods in the prior art include heating and drying methods. This dehydration and drying method has a relatively large negative impact on the coal itself, such as the natural coal quality reduction caused by the high-temperature heating process of the coal.
