Abstract
Sintered board and porous board was used to be gas distributor of air-dense medium fluidized bed in the experiment, the influence of different gas distributor settings to fluidization and separation characteristics was investigated; The results showed that, under the same conditions, the pressure drop of sintered board gas distributor is greater than porous board gas distributor. The pressure drop of gas distributor is proportional to the layers of filter cloth and air volume. The uniformity and stability of sintered board gas distributor with 1 layer filter cloth is bad, sintered board gas distributor with 2 layers filter cloth and porous board gas distributor with 5 or 6 layers filter cloth can obtain a better fluidizing effect; Conducting separation experiment on fat coal of 50 ~13mm under the suitable air volume, porous board gas distributor with 5 layers filter cloth has the best separation accuracy, and its probable error Ep value is 0.05 g/cm3.
