The utility model discloses a high-pressure spray injection dust reducing device which is composed of an air inlet pipe (1), a water supply pipe (2), a throat pipe (5) and a folded plate (3) arranged in the throat pipe (5), wherein a spray head (4) is arranged at a water outlet end of the water supply pipe (2); the spray head (4) is positioned at the middle part of the air inlet pipe (1) and corresponds to the throat pipe (5); the spray head (4) consists of a rotatable core body and a shell; the shell is screwed on the core body; a nozzle of the spray head (4) is a Venturi nozzle. The device disclosed by the utility model is mounted on a cyclone dust remover and forms series connection with the cyclone dust remover so that the air, water mist and fine dust are sufficiently mixed and the dust of different particle sizes is graded; relatively high dust removal efficiency is realized against the dust and particularly fine dust (<10 microns). The device can be widely applied to the purification of the dust-contai
