System to Apply Mainly Phytosanitary Products that use the Principle of Electrostatic Attraction

A high flow electrostatic sprayer comprising:

• a bar comprising a tube defining a hollow internal space that is sealed at opposite first and second ends, said tube adapted to receive pressurized air from an associated source into said internal space;
• a nozzle comprising a nozzle body mechanically and electrically connected to said bar for receiving an electrical charge from said bar, wherein said nozzle body comprises an inlet in communication with the internal space and an outlet located external to said internal space and an internal channel that connects said inlet to said outlet such that pressurized air within said internal space can flow outwardly through said nozzle body;
• a water collector tube located within the internal space of the bar and adapted to be connected to an associated source of water, said water collector tube connected to said bar by a plurality of internal supports, said water collector tube comprising an electrical ground path;
• a capillary tube in fluid communication with said water collector tube and electrically connected to the electrical ground path of said water collector tube, wherein said capillary tube are located within the internal channel of the nozzle body such that liquid ejected by said capillary tube within the internal channel will be micronized into droplets by pressurized air flowing from the inlet of the nozzle body to the outlet of the nozzle body and said micronized droplets will be ejected from said outlet of said nozzle;
• a bar support that is connected to the bar but electrically isolated from the bar, said bar support adapted for connection to an associated sprayer machine structure, wherein said fastening support is electrically connected to said electrical ground path of said water collector tube;
• a dosing system has for injecting chemical products directly into the nozzle body, said dosing system comprising:
• a chemical product conduit located within the internal space of the bar and adapted to be connected to an associated source of chemical product, said chemical product conduit connected to said bar by said one or more internal supports;
• a hollow chemical supply needle associated with said nozzle, wherein said chemical supply needle is in fluid communication with said chemical product conduit at a first end and is in fluid communication with said nozzle body at a second end such that associated chemical products are communicated from said chemical product conduit to said nozzle body.
