Area buffering and modularization indirect heating fluid -bed coal dryer in cloth district again

The utility model provides an area buffering and modularization indirect heating fluid -bed coal dryer in cloth district again, fluidized drying room front end are provided with buffers, the buffers front end is connected the feeding and is separated formula dispenser, rear end linking module ization indirect heater, the air distribution plate upper surface with there is again the cloth district between the modularization indirect heater bottom, the cloth district is for transversely lining up the structure again, and the export of the thick dry coal of its end -to -end connection separates the formula dispenser, its advantage has improved desiccator production variation in load adaptability, the buffers active absorption flow that causes of feeding pulse stability problem not, the cloth is even rapidly, cloth district has adapted to the characteristic that the coking coal grade differed greatly again, make coarse grain level material can be once more fluidization and pack rapidly to the clearance of the snakelike tube bank of each heating module and abundant heat transfer is difficult to the jamming and hardens the jam again, therefore can reduce fluidization fan consumption about 10%, under the equal -volume condition, the drying process ability can improve 20%, and the dust productivity can reduce by 30%.
