| titleOfInvention | A kind of method of fuming furnace tail-gas deep purification |
| abstract | The present invention relates to a kind of method of fuming furnace tail-gas deep purification, belong to field of environment engineering technology, the present invention uses ammoniacal liquor hydrogen peroxide as desulfurizing agent, front and rear combined running, to the SO in fuming furnace exhaust gas 2 The deep purifying for carrying out, leading portion SO 2 Absorptive capacity is larger, back segment SO 2 Absorbing reaction is rapid, and by-product propylhomoserin absorption mother liquor and sulfuric acid solution, and propylhomoserin absorption mother liquor is used to produce solid ammonium sulfate, and sulfuric acid solution returns to leading portion flow reuse, do not produce waste liquid, SO in the tail gas after treatment 2 Concentration is less than 50mg/Nm 3 , the qualified discharge of tail gas 100%, raw material is easily purchased, process is simple, easy to operate. |
