The wet slime is fed into the slime special dispersing feeder by the forklift, and then the slime is dispersed into small pieces by the belt feeder into the feeding end. The slime goes into the drying cylinder along the guide pipe. The heat generated by the combustion of pulverized coal combustion furnace enters into the main engine under the action of the extraction fan and contacts with the slime. Under the action of the plates in the dryer and the dispersive device, it is evenly dispersed and fully contacts with the hot air, which speeds up the heat transfer and mass transfer of the drying. Slime dryer installation is a slightly inclined drum with the horizontal line, with the rotation of the drum material by gravity to run to the bottom end. Finally, the material is discharged through the discharge valve at the discharge end and transported to the storage place by the conveyor. After the hot gas produced by pulverized coal combustion furnace passes through the slime dryer, the cyclone dust collector is generally needed to collect the material in the gas. If it is necessary to further reduce the dust content of the tail gas, it should also go through the bag dust collector or wet desulfurization and other equipment, which can well achieve the purpose of environmental protection.
