Dual flow velocity high-efficiency electrostatic precipitator

The utility model discloses a dual flow velocity high-efficiency electrostatic precipitator, which relates to a dust removing device for curbing atmospheric dust pollution and solves the problem that dust removing efficiency of flue gas with a high flow velocity is low after the flow section and the electric field length of a line-plate electric dust remover in the prior art are determined. The dual flow velocity high-efficiency electrostatic precipitator comprises a shell with an inlet smoke box and a flow equalizing device, a front stage electric field and a rear stage electric field are arranged in the shell, an electrode plate of the front stage electric field is horizontally positioned, an electrode plate of the rear stage electric field is vertically positioned, a flow guiding and equalizing device is arranged between the front stage electric field and the rear stage electric field, the width of the rear stage electric field is not smaller than that of the front stage electric field, in the rear stage e
