Influence of Electric Field Frequency on the Process of Destruction of Water-Oil Emulsions in Electric Dehydrators

详细

The effect of electric field frequency on the processes of destruction of water-oil emulsions in electric dehydrators is investigated. It is shown that the existing theoretical concepts regarding the processes of deformation, destruction, coagulation, and coalescence of droplets, and data available in the literature should be considered for three characteristic cases of an electric field being applied to the emulsion: a constant electric field; an alternating electric field with a frequency below the critical value; an alternating electric field with a frequency above the critical value. It is concluded that the effect of electric field frequency on the process of destruction of industrial water-oil emulsions in electric dehydrators is most pronounced under the influence of an alternating electric field with a frequency below the critical value in the working zone of the electric dehydrator, which has the shape of a confuser or a channel with a constant cross section.
