摘要： The present invention relates to a multi baffle dryer increasing drying efficiency because the dryer has multiple zigzag baffles with a downward gradient. According to the present invention, coal is bumped into a baffle and falls down to have a long contact time with air. A warm current is formed from rising air by the baffle and is in contact with the coal to increase drying efficiency. Further, the coal is put into the upper part of the dryer, and air flows from the lower part thereof, so that the temperature is increased while the coal falls down, and the temperature is lowered while air rises. Therefore, the entire dryer has constant driving force required for drying, thereby increasing drying efficiency. Also, the dryer of the present invention further promotes drying by vacuum drying effects by forming a high pressure gradient in the vertical area of the baffle, and thus, the dryer can efficiently dry the coal with a small amount of air flow during a short contact time at relatively low temperatures (200°C or less).

摘要翻译：本发明涉及多挡板干燥器，其增加干燥效率，因为干燥器具有多个具有向下梯度的曲折挡板。根据本发明，煤被撞到挡板中并且落下以与空气具有长的接触时间。暖风通过挡板由升高的空气形成，并与煤接触以提高干燥效率。此外，煤被放入干燥器的上部，空气从其下部流出，使得当煤落下时，温度升高，空气升高时温度降低。因此，整个干燥机具有恒定的干燥驱动力，从而提高了干燥效率。此外，本发明的干燥机还通过在隔板的垂直区域中形成高压梯度，通过真空干燥效果进一步促进干燥，因此干燥器可在短时间接触期间以少量的空气流量有效地干燥煤时间在较低的温度（200℃或更低）。（附图标记）（AA）煤; （BB）干煤; （CC）排放空气; （DD）粉煤; （EE）热风
