1.Description

Bulk solids can be transformed from a fixed bed into a fluidised bed when liquids or gases pass through them. The areas of application of fluidised beds include the drying of solids and a wide variety of chemical processes.

 

A diaphragm pump delivers water from a storage tank into the bottom of the left side test tank. The water flows upwards through a porous sintered-metal plate. On the sintered At the time of the water is less than the so-called fluidisation velocity, the flow only passes through the fixed bed. At higher velocities the bed is loosened to such an extent that individual solid particles are suspended By the fluid. If the velocity is increased further, particles are carried out of the fluidised bed: transport takes place. Transport is only possible with the experimental unit. A filter at the top of the test tank holds these particles back. Water flows back into the storage tank.

 

The right-side test tank is similar to construction to the left-side one. An air flow generated by a compressor flows through it.

 

Manometers are mounted on both test tanks to measure the pressure loss. The flow rates are adjusted by way of valves, and can be read from flow meters. The test tanks are removable. This makes it easy to change the bulk solid filling.

 

Glass-shot beads in a range of particle sizes are provided as the bulk solid filling.
