| titleOfInvention | A system for purifying waste water by utilizing waste heat from smelting flue gas to make acid |
| abstract | The utility model discloses a system for purifying waste water by utilizing the waste heat of smelting flue gas for acid production, comprising a washing tower, the outlet of the washing tower is connected to a storage tank, the storage tank is connected to a cooling tower, the top outlet of the cooling tower is connected to an electric demister, and the electric demister The bottom outlet is connected to the second dilute acid circulating pump, the cooling tower is also connected to the second dilute acid circulating pump, the second dilute acid circulating pump is respectively connected to the plate heat exchanger and the storage tank, the plate heat exchanger is connected to the cooling tower, and the bottom outlet of the storage tank is also connected. It is connected to the first dilute acid circulating pump, and also includes a degassing tower, the top outlet of the degassing tower is connected to the storage tank, the bottom outlet of the degassing tower is connected to the neutralization tank, and the bottom outlet of the neutralization tank is connected to the plate and frame filter press through the slurry pump. The outlet of the frame filter press is connected to the neutralization pool, the neutralization pool is connected to the clean water pump, and the clean water pump is connected to the cooling tower. The system of the utility model makes full use of the limited thermal energy carried by the low-temperature flue gas to evaporate and purify the waste water of lime neutralization and calcium sulfite, and save the energy consumption of the treatment of calcium sulfite waste water. |
