Cooling and drying synchronizing method for rotary hearth furnace

The invention relates to a cooling and drying synchronizing method for a rotary hearth furnace. The method specifically includes the following steps that firstly, red pellets of the rotary hearth furnace uniformly fall on a lower-layer chain plate at a feeding end A2 through a first guiding chute, and meanwhile green pellets of the rotary hearth furnace uniformly fall on an upper-layer chain plate at a feeding end B1 through a first distributor; secondly, it is guaranteed that the rotation direction of the upper-layer chain plate and the rotation direction of the lower-layer chain plate are opposite by adjusting the rotating speed of both the upper-layer chain plate and lower-layer chain plate; thirdly, cold air ascends and penetrates through the red pellets on the lower-layer chain plate so as to cool the red pellets, and meanwhile the temperature of the cold air increases, so that the cold air is changed into pre-heated air; fourthly, the pre-heated air continues to ascend and penetrates through the green pellets on the upper-layer chain plate so as to dry and pre-heat the green pellets, and meanwhile the temperature of the pre-heated air decreases, so that the pre-heated air is changed into hot air containing certain heat; and finally, the hot air is pumped out, enters a dust falling room, then enters a dust removing room from the dust falling room and is transferred into an air pre-heating system in the rotary hearth furnace through the dust removing room for use.
