DEVICE FOR ELECTROSTATIC DEWAXING OF SUMMER TYPES OF FUEL IN FLOW MODE Russian patent published in 2020 - IPC C10G73/30 

FIELD: fuel industry.

SUBSTANCE: invention relates to a device for electrostatic dewaxing of summer diesel fuel types in flow mode, comprising an electric field source and a cell for electrostatic dewaxing, including first and second cylindrical electrodes connected to electric field source poles, wherein first cylindrical electrode is arranged inside second cylindrical electrode with gap between first and second electrodes, wherein they are configured to form a coaxial system of electrodes isolated between each other and possibility of filling the gap between the first and second electrodes with diesel fuel. Device is characterized by that the first (internal) cell electrode is made mesh and fixed on upper and lower ends of the second cylindrical electrode by means of insulators, wherein in the ends of the first (internal) electrode there are inlet and outlet plugs with through holes in their center along the axis of these plugs, made of electrically insulating material, and on ends of second cylindrical electrode first and second flanges made of metal are installed, wherein inlet and outlet plugs through first and second flanges are respectively inserted inlet and first outlet nozzles, and annular insulator located opposite input plug, is configured to pass through it diesel fuel with paraffin concentrate through holes along its perimeter and first flange, as well as a second outlet nozzle connected to them, wherein the outlet plug has a trapezium or cone shape, the vertex of which is directed inside the volume of the first (internal) cylindrical electrode.

EFFECT: device enables to obtain dewaxed, low-solidified fuel and paraffin components of fuel from summer grades of fuel, by dewaxing said fuel in flow mode in a constant nonuniform electrostatic field, which is created in the disclosed device.
