Application Research on High-efficiency Separation Technology for Gas-liquid Two-phase Impurities in Copper Smelting Flue Gas
Efficient separators and filter presses were used to optimize the process flow of copper smelting flue gas acid production system in the purification process,and this technology was applied to project production practice.The application results show that the combination of washing and separation equipment reduces the dust concentration of the first stage power wave circulating liquid from 2000 mg/L to 300 mg/L,reduces the amount of acid discharge by 20％,recovers 1.5 t/d of acid sludge,and achieves efficient separation of gas-liquid two-phase impurities in the copper smelting flue gas acid production process.This technology provides a method and approach for upgrading other purification control technologies.
