Phosphorus fertilizer tail washing fluorine absorption and purification treatment device

The utility model discloses a phosphorus fertilizer tail washing fluorine absorption and purification treatment device which is characterized in that a Venturi absorption tower is connected with a first absorption tower, the first absorption tower is connected with a second absorption tower in series, the second absorption tower is connected with a water mist absorption separator through a pipeline, and the water mist absorption separator is connected with a chimney through a tail washing fan. Fluorine-containing tail gas generated in the phosphorus fertilizer production process is subjected to three-stage washing, then residual moisture in the gas is further removed through water mist separation, finally, the gas reaching the emission standard is discharged through a chimney, and fluorine-containing water generated after washing enters a circulating tank for secondary recycling or enters a fluosilicic acid transfer tank for storage. And further recycling is facilitated. The fluorine recovery device is high i
