An electrostatic spraying device and electrostatic spraying method provided in the present invention comprise: a glaze storage and adjustment apparatus, used for storing and stirring a glaze; a transfer isolation apparatus, used for receiving glaze from the glaze storage and adjustment apparatus; an electrostatic rotary bell spray gun, used for receiving glaze from a glaze transfer isolation barrel and spraying glaze onto a blank to be glazed located on a glaze line; a smart PLC controller, connected to the glaze storage and adjustment apparatus, the transfer isolation apparatus, and the electrostatic rotary bell spray gun; and a high-voltage electrostatic generator, connected to the electrostatic rotary bell spray gun and used for electrifying the electrostatic rotary bell spray gun. The present invention utilizes the glaze storage and adjustment apparatus to store and stir glaze, uses the transfer isolation apparatus to convey glaze to the electrostatic rotary bell spray gun, and uses the electrostatic rotary bell spray gun for uniformly atomizing and coating a fully-water-based thin-layer glaze onto large-sized glaze product blanks in the architectural ceramics industry. The invention solves the technical problems in the industry whereby, when the traditional water-based electrostatic spraying industry is applied to the field of architectural ceramics, glaze accumulates in the rotary bell, glaze drips down a glaze compartment, dirt and slag fall, and electricity is prone to leakage.
