1. Product Introduction
1.1 Product Description
Flow-through particle beds are widely used in engineering and process technology. In reactors, liquids and gases flow through fixed beds and fluidized beds. Another application area is the separation of solid particles from suspensions through sedimentation and deep filtration.
This experimental setup can be used to study the fluid dynamics principles associated with flow-through of fixed and fluidized beds. For this purpose, the experimental setup provides a fillable glass test tank through which water can flow from both ends. Sintered metal plates serve as supports for the bulk material. Water from a laboratory water supply system enters the test tank.
To study flow-through of a fixed bed, water enters the test tank from above. It flows through the fixed bed and sintered metal plates, then through a distributor to the outlet. The experimental setup can be modified using quick-connect fittings. This also allows reversing the direction of flow through the test tank to study fluidized beds.
Water flows upward through the porous sintered metal plates and the fixed bed. If the water flow velocity is below the so-called fluidization velocity, the water will flow directly through the fixed bed. When the water flow velocity is higher, a fluidized bed is formed. Water then flows from the top of the test tank into the expansion tank and exits from there.
Regardless of the specific configuration, the flow rate is regulated by valves and indicated by a flow meter. To determine the pressure loss in a fixed or fluidized bed, we provide two pressure gauges with different ranges. The required pressure gauge is selected via the valve.
