A method for cooling and purifying a bus stop through electrostatic spraying is used for conducting local cooling and local dust removal on the bus stop and is characterized in that the method is applied to an electrostatic spraying dust removal system; the electrostatic spraying dust removal system is installed on the bus stop and composed of a nozzle, an electrostatic device, a liquid conveying pipeline, a pressurizing device, an electric device and a liquid storage tank; the liquid storage tank is connected with the nozzle through the liquid conveying pipeline; water is stored in the liquid storage tank; the pressurizing device is arranged in the position, close to the ground, of an upright of the bus stop and connected with the electrostatic device and the electric device; when external pressure is received by the pressurizing device, starting signals are sent to the electrostatic device and the electric device by the pressurizing device; the electrostatic device is started to conduct local dust removal and the electric device is started at the same time, so that the water in the liquid storage tank is driven to enter the nozzle through the liquid conveying pipeline and water mist is sprayed from the nozzle to conduct local cooling. According to the method for cooling and purifying the bus stop through electrostatic spraying, the requirements for health and the comfort level of people can be satisfied when people are waiting for buses at the bus stop.
