Abstract:
A method for spraying crops with an electrostatically charged liquid with an electrostatic spray module, the method comprising the steps:converting a low voltage from a low voltage power source to a high voltage signal, the low voltage power source connected to the electrostatic spray module;delivering the high voltage signal to an electrostatic spray nozzle across a gas delivery pipe made of an electrically conductive material;carrying a ground voltage across a liquid delivery tube made of an electrically conductive material;delivering a liquid to the spray nozzle through the liquid delivery tube, the liquid drawn from a liquid supply connected to the electrostatic spray module;delivering compressed air to the nozzle through the gas delivery tube, the compressed air delivered from a supply of compressed air connected to the electrostatic spray module;mixing the liquid and the compressed air in the spray nozzle to form an atomized liquid;charging the atomized liquid by an electrode in the spray nozzle, the electrode charged by the high voltage signal delivered to the nozzle;spraying the crop with the charged atomized liquid.
