Spray dust-removing device for pre-classification of silicon carbide micro-powder

The utility model relates to a dust-removing device, in particular to a spray dust-removing device for pre-classification of silicon carbide micro-powder, which is characterized by comprising an air inlet pipe (1), a draught fan (2), a centrifugal fan (3), a water tank (4) and a spray head (6), wherein the air inlet pipe (1) is connected with an air inlet of the draught fan (2), and an air outlet of the draught fan (2) is connected with the centrifugal fan (3) by an air pipe; the centrifugal fan (3) is connected with the water tank (4) by the air pipe; an air outlet pipe (5) is arranged at an opening on the top of the water tank (4); the spray head (6) is arranged above the air outlet pipe (5); and the side of the top of the water tank (4) is provided with a water outlet pipe (7). The spray dust-removing device for the pre-classification of the silicon carbide micro-powder is better in dust-removing effect and saves the production cost.
