The invention discloses an electrostatic powder vertical type spraying device. The electrostatic powder vertical type spraying device comprises a powder spraying house, a conveying device for conveying workpieces, a powder spraying device, a powder supplying device and a powder recycling device. The powder spraying house is provided with a workpiece input port and a workpiece output port both of which correspond to the conveying device. The electrostatic powder vertical type spraying device is characterized in that the powder recycling device comprises exhaust pipes arranged at the four corners of the powder spraying house respectively, and each exhaust pipe is provided with a gap for exhausting air from bottom to top, so that air flow in the powder spraying house is uniform and the negative pressure of air needing to be exhausted is reduced; the powder spraying device comprises electrostatic spray gun sets oppositely arranged on the two sides of the conveying device and a lifting device driving the electrostatic spray guns on the two sides to synchronously ascend and descend. The electrostatic powder vertical type spraying device is simple in structure and convenient to use and install; in the powder spraying production process, powder consumption is low, the one-time powder coating rate is high, the time taken to clean the powder house and the time taken to change powder are shortened, electric energy is saved, fewer operating workers are needed, and the production cost is greatly reduced.
