Abstract

The present invention relates to a multiple baffle plate drier of enhanced drying efficiency, wherein a plurality of downward-sloping baffle plates are formed in zig-zag fashion inside the dryer. When the present invention is employed, coal falls and strikes the baffle plates and, while so doing, the time spent in contact with the air is prolonged, and upwardly rising air forms turbulent flow before coming into contact with the coal due to the baffle plates and thus the drying efficiency is increased. Also, the coal is introduced into the upper part of the dryer and air flows in from the bottom part, and thus the temperature of the coal rises as the coal falls while the temperature of the air drops as the air rises, such that the drive force required for drying is constant in the dryer as a whole and the drying efficiency is increased. In addition, with the dryer of the present invention, a high pressure gradient is formed in the areas above and below the baffle plates, such that drying is further promoted due to a vacuum drying effect. Consequently, the dryer of the present invention can efficiently dry coal even at relatively low temperatures (of 200°C or below) and even with a small volume of airflow and a short contact time.
