| titleOfInvention | A fluorine-containing nitric acid, hydrofluoric acid or ammonium fluoride liquid treatment device |
| abstract | The embodiment of the utility model discloses a treatment device for fluorine-containing nitric acid, hydrofluoric acid or ammonium fluoride liquid, comprising a first reaction kettle, a first precipitation tank and a second precipitation tank respectively connected with the first reaction kettle, The other ends of the first precipitation tank and the second precipitation tank are respectively connected with the second reaction kettle and the third reaction kettle, and the second reaction kettle is connected with a third condenser and a fourth condenser, and the third The reaction kettle is connected with a first condenser and a second condenser, and the condensate produced by the first condenser, the second condenser, the third condenser and the fourth condenser flows to the first distillate tank, In the second distillate tank, then respectively through the first distillate pump and the second distillate pump, the residual tail gas from the second condenser and the fourth condenser is sent to the first-level absorption tower and the second-level absorption tower in turn, The absorption liquid absorbs the tail gas entering the tower through the countercurrent exchange of the primary and secondary absorption circulating pumps, providing a harmless treatment of waste water and reducing waste water discharge and environmental pollution. |
