EXPERIMENTAL STUDY ON FINE PARTICLE CONCENTRATION DISTRIBUTING IN THE JET REGION OF A JETTING FLUIDIZED BED

Experiments were carried out to study the concentration distributing of fine particles in the jet region of a 1 m dia and 8 m high semicircular jetting fluidized bed with a conical distributor.The particle concentration was measured with PC-4 optical fiber probe system and local-sampling.The average size of large particle is 1.2 mm.Fines,-80+160 mesh with an average size of 138 μm,were injected coaxially to simulate fines recycle back to the jet region in an actual operating unit at different fines feed-in quantity.It was found that there is a high fines concentration region existing in the jet region of fluidized bed.The fine particle concentration increases along the radial direction firstly,and then decreases.When reaching certain bed height,the absolute volume fraction of fines begins to decrease along the axial direction.Two kinds of fines with different feed-in quantity,fines concentration in jet region increases proportionally with fines feed-in quantity.When the feed-in quantity of fines is low,its high concentration zone is not obvious and the fines concentration near distributor is higher.Otherwise,high fines concentration in jet region is more significant.
