| titleOfInvention | Recovery process for purifying waste acid by making acid from smelting flue gas |
| abstract | The invention discloses a recovery process for purifying waste acid by making acid from smelting flue gas, belonging to the field of environmental protection in metallurgical chemical industry, wherein the process has no lime neutralization process and no gypsum waste residue; valuable metal copper is recycled, so that the amount of hazardous waste residues is reduced, and economic benefits and environmental protection benefits are created; waste heat utilization is carried out on the waste heat of the smelting high-temperature flue gas, and the circulating water consumption of the purification process is reduced; the addition amount of the activated sulfur is small, and the operation cost is low; lime or limestone is not added in the sewage treatment process, no gypsum solid waste is generated, and the method is an energy-saving, consumption-reducing and emission-reducing sewage acid purification treatment technology; purifying the waste acid generated by washing in the working procedure by activating sulfur and high-temperature SO 2 The flue gas, selectivity fractional separation deposit copper, arsenic, the dirty sour acid after the separation evaporates out fluorine and chlorine in it through the high temperature flue gas classification that the system produced of smelting, through deposiing and evaporating, separates the harmful impurity in the dirty sour acid, satisfies the requirement that dirty sour direct retrieval and utilization. |
