In this paper, a new method
for the improvement of the performance of magnetic filters for the removal of
disperses mixtures with magnetic characteristics from industrial liquids and
gases are investigated. In order to accelerate the reduction of the
concentration of dispersed mixture, it is suggested that the intensity of the
external magnetic field throughout the magnetic filter should be adjusted
regionally. In order to achieve this goal, an intermediate control circuit with
PWM (Pulse Width Modulation) driver capable of driving the external magnetic
fields of magnetic filter regionally based on three regions was designed. The
dsPIC30F2010 Digital Signal Controller (DSC; Microchip^®) is used in
the controller circuit. The experimental results shows that the concentration
of dispersed magnetic mixture contained in the aqueous suspension passed from
magnetic filter is reduced more efficiently. It is claimed that due to the
adjustment of the external magnetic field intensity applied to the magnetic
filters throughout the magnetic filter, the filter performance is increased,
the electrical energy consumption is reduced, and the optimum design of magnetic
filters is achieved.
