双円錐付き固液噴流層内における粒子層高さ

抄録

A new apparatus of spouted-bed is proposed, which has a biconical device in fluid inlet. The device is shown to enhance particle-dispersion in the apparatus by controlling the fluid-blowout. Dispersion experiments are carried out using several kinds of solid particles in water flowing at various velocities to obtain the variation in the height of particle-bed with some operating conditions. It is shown that the height increases with increasing both the water velocity and the particle amount but decreases with increasing the particle size and density. By the consideration of such tendencies, a correlation equation is proposed, which expresses the height with water superficial-velocity, particle volume-fraction and particle terminal-settling-velocity.
