Silicon powder processing tail gas washing device

The utility model discloses a silicon powder processing tail gas washing device which is characterized in that a washing structure is assembled on a washing tower, the exhaust end of the washing tower is fixedly communicated with an exhaust pipe with a valve, and the right end of the exhaust pipe with the valve is fixedly communicated with a dust removal mechanism; tail gas entering the washing tower is primarily sprayed and cleaned through the washing structure, the entering tail gas is guided upwards through the inclined plate, the tail gas guided upwards is primarily sprayed through the spraying holes in the arc-shaped cavity plate at the lower end of the inner wall of the washing tower, and then secondary spraying is conducted through the spraying heads on the bottom face of the cavity circular plate above the spraying tower. Upper spraying is pressurized through a booster pump and is intersected with spraying water of high-pressure water supply of the side wall, so that the tail gas which is guided upwar
