Abstract:
A system for purification of contaminated fluids by use of non-thermal plasma produced by dielectric gas phase corona discharge, said system comprising:a housing provided with a fluid inlet and a fluid outlet; a corona discharge reactor means arranged in said housing for passage of the contaminated fluids therethrough, said reactor means comprising: upper and lower frame elements, and a plurality of spaced-apart oppositely charged electrodes being supported by said frame elements, arranged as a plurality of adjoining triangular modules, each of said electrodes having a conducting element surrounded by an insulating jacket, said plurality of electrodes being arranged perpendicular to said frame elements in rows of alternate polarity wherein spacing between said electrode rows of alternate polarity is less than or equal to a diameter of said electrodes; and a fluid swiveling means in fluid communication with said corona discharge reactor means for creating and directing a turbulent flow of said fluid through said reactor, such that when an electrical power supply is connected to said electrodes, a substantially uniformly distributed plurality of electrical microdischarges is produced, said electrical microdischarges reacting with constituents of said fluid to produce activated radicals, said fluid swiveling means providing high exposure of said fluid to said electrical microdischarges, such that contaminants contained in said fluid are attacked and decomposed by said radicals.
