The working principle of quality Vibrating fluidized bed

2021-12-07 11:07

The quality Vibrating fluidized bed If a material layer is placed in the vibration space, the following phenomena will occur: as the vibration acceleration increases, the material layer gradually compacts; when the acceleration value is close to the acceleration of gravity (9.81m/s2), the density of the material layer reaches the maximum . If the vibration acceleration of the vibrating fluidized bed is further increased, the material bed will begin to expand and the so-called vibrating fluidized state will appear.

The materials placed on the vibrating surface of the quality Vibrating fluidized bed are strongly mixed and can be easily moved horizontally or obliquely, and can also be transported upward (or downward) along the spiral surface. In this case, if heat is input to the material layer by conduction, convection, radiation, or a combination thereof, the material can be dried.

The quality Vibrating fluidized bed is to increase the vibration of the bed on the basis of the fluidization of the material, so that the material has a dispersion process, and the two organically combine to achieve the fluidization effect of the low bed. Different from the traditional fluidized bed dryer, the material transportation and fluidization of the ordinary fluidized bed dryer is completed by wind (hot air), while the vibrating fluidized bed is mainly completed by vibration. It can reduce the minimum fluidization speed of the material, especially the particles near the bottom fluidize first, which improves the fluidization quality of the bottom particles, so that some materials that are difficult to fluidize can be dried normally.
