ALPHA CHEM-1323 Fixed and Fluidized Bed Apparatus

The simutaneous study of air and water systems and the phenomenon of ‘bubbling’ can be observed.

The apparatus comprises three clear acrylic columns mounted above a moulded ABS base. The base contains a water reservoir with a variable speed submersible pump, which pumps water through an electronic flow meter into the base of the left hand column. This column features an overflow pipe, which returns the water back into the sump.

The two air columns are fed by variable pressure regulators, which can be used to adjust the air flow rate through the column. The air flow rate is measured using pressure sensors at discharge orifices at the top of the columns. The integral microcontroller calculates the flow rates from the pressure readings and displays these on the front panel.

Pressure drops on all three columns are measured by differential pressure sensors connected to tapping points at the top and bottom of the columns. All process measurements are displayed simultaneously on the front panel display and are available on the USB output for data logging. The software also provides powerful graph plotting facilities.

Specification :

A benchtop apparatus for the study of fixed and fluidised beds of solid particles

Three cylindrical columns, one for water and two for air, each column with a diameter of 50mm and height of 550mm

Columns mounted above a blue ABS moulded base containing an eight litre water reservoir

Two sizes of bed material supplied, ranges: 0.5 to 0.75mm and 0.2 to 0.3 mm 

Complete with a demonstration of liquefaction and how the properties of liquefied particles change with agitation

Variable speed submersible pump to recirculate water, rate up to 2 l/min

Each column has tapping points and differential pressure sensors

Air flow rate measured by orifice pressure sensors, the flow rate being calculated by an integral microcontroller

Electronic front panel display shows flow rates and pressure drops for all three columns simultaneously

Powered by universal power adaptor with worldwide approvals
