Disclosed are non-closed passage type mechanical energy auxiliary powder zinc impregnation equipment and process. The equipment comprises a non-closed passage type zinc impregnation chamber, a heating and thermal insulation system, a shielding gas application device, a zinc powder application device, a mechanical impregnation auxiliary device and a delivery system, the non-closed passage type zinc impregnation chamber has a passage composed of a plurality of sections, a workpiece inlet is formed in one end of each section, a workpiece outlet is formed in the other end, and one or more sections serve as zinc impregnation sections, wherein there is zinc impregnation space; the heating and thermal insulation system is used for heating the zinc impregnatino space; the shielding gas application device is used for filling gas in the zinc impregnation space to make a metal workpiece to experience zinc impregnation treatment under the atmosphere of gas protection; the zinc powder application device is used for applying zinc powder on the surface of the workpiece; the mechanical impregnation auxiliary device is used for applying particles on the surface of the workpiece, and mechanical impregnation assistance is achieved through impacting the workpiece surface on which the zinc powder is applied by the particles; one part of a preset route on which a workpiece delivery part delivers metal workpieces is distributed along the workpiece inlet, the passage and the workpiece outlet. In this way, continuous zinc impregnation can be achieved, and compared with an existing successive furnace zinc impregnation process, the non-closed passage type mechanical energy auxiliary powder zinc impregnation process is high in efficiency, energy-conserving and environmentally friendly.
